NEO DevCon 2019 DAY 2 Live Streaming 2019/02/17

Coindesk. Everybody makes that mistake every time. Thanks

everyone for coming so early in the morning. The title of the

talk is cryptoeconomics and data metrics for the next market

cycle. The purpose of it is to give you guys an insight on how all of your is going to be interpreted when the market shifts in the next year or two There is a lot of data projects going on right now, so this is a bit on after overview of that as well as friends, but anytime we are talking about the future, it’s a pretty good lesson to go into the past to find out about the trends and the reasons thing s happen. We will start this with the original 2013 price spike and the companies that won. Coindesk was one of them. We said there is spot market prices in London, Tokyo, Hong Kong and a lot of people were making money tread ing trading these those cities and we said let’s try to shrink that arbitrage and let’s shrink the price. It did set the trend for global pricing. The other important data service that set the mark was This data service was foe focused on the performance of the blockchain. They look looked at mem pool size and others. These are really the two winners and the two things they achieveed with global index pricing and blockchain performance metrics. Not much ended up happening in the bare market after. We saw in 2017 with the crypt to currency proliferation was that coin market cap became the Big Data winner. They were offering something no one else was, showing the market and exchange activity across a broad section of coins that a lot of people weren’t paying attention to Even at Coindesk, we said it’s so deep how are we going to pay attention to more than 100 coins , and these guys did. It was a really big innovation and we were checking it every day constantly and that led to a powerful base and powerful platform and product, so the three things that has been done, with the global index price — ex exchange and showing the flows from each asset and trade pair. What we are seeing now is a pretty interesting thing. So after all the ICOs and races, there is a premium on seeing what is being delivered, so we are seeing a lot of development theater and data services are springing up around GitHub. GitHub code trackers have become a very important service This one is tracking what is going on in different repos and different chains. Crypt meso is very much the same. That has become the definition of orphan ed and abandoned project when the GitHub goes dead. We can see exchange data what coin market cap did. These are important and lots of people are covering them. Important to think of what is happening next Exchange data is a part of it, hashrate not so interesting in this room of course but for a lot of platforms very, very important, social data, more and more important you are seeing a lot of services measure measuring who is chats about a thing, what platform is it, is it Reddit, is it Twitter Development data is a big one When you start putting these data services together we arrive in a point where we are out in the industry measuring how these networks grow. This is where we get into the field of cryptoeconomics. It is economics like we all know, making decisions and it is a subcategory of service design

and engineering and how decentralization decentralization networks through grow through the network s that shape their growth. If you combine them all, they give a topographical map of these what data services can look like and they end up being five pillars of this. We did a Coindesk because we added all these five together and turned it into a cryptoeconomics explorer, a way to judge the different networks. This is NEO from January 1-February 14. We took all the data points and measureed them across five different axe a different axis. We are measureing repo for the core property tol. It’s not necessary a sign of progress if you are going back and thee tet ry scaling — is a good sign We see important networks like network important networks gaining steam. This is the five point product we createed at Coindesk to measure all of these forces Now, this one is a little bit heavy on hashrate for network score so that is why NEO doesn’t have a very high score on this, but the methodology is still in beta, so still trying to find a comfort zone and adding more data points and points of reference. That is why we need your help. We have open sourc ed this entire methodology and data sources on GitHub and in the spirit of cryptoeconomics we are opening it to everyone especially the NEO community and other the other communities. We want to track dap accommodate D ap activity and wag let activity wag let activity activity. Tell us the data points that we are missing and we will start adding those into our database, so the cryptoeconomics part is through GitHub all of people’s contributions are tracked, so we will be offering a coin and that will only betrayedable for tickets to our events and things like that, not looking for a secondary trading of the coin, we are the sole buyer of the coin but it will go to tickets and fun services. Just the main GitHub repo you can see NEO there and we are looking for help to expand and that further What we really see is the trend going forward will be these five bucket buckets, these five pillars are going to be thousand data how the data service services come together and measure the growth of a decentralized network. What is going on social media, who is using it, are they trading on ex changing, who is working on and building on the GitHub, these five things become a way collect collectively a way to measure the cryptoeconomics forces and conjure up these project, so we hope all of the work will come into your platform and we will be able to measure your product and it will come out in the find product. It won’t just be us Lots of people in the industry are trying to find a way to come wine these data points points Cain point. Coingecko is doing the same thing. They are tracking things that are going on the in the network. This is what the market is going to use to measure growth in the next market cycle and looking for the new big winner on data services as we have seen before. That is the presentation and we would love for you to contribute to the project, so whatever you are going please go on our GitHub and open up a pole request and let us know what we should be tracking. Thanks so much >> Thank you Nolan

Sorry about screwing up the very first part of the day. Next up we have — I am going to screw up err time I come up here Buoying buoying he is the co- founder and technical Director of NSPCC. I need the clicker I think we have lost it already Thank you very much (applause) >> Hello everyone. My name is Anatoly. I am glad to be here today. I will tell you about our core project and our activities. L we are the NEO group in St. Petersburg NEO SPCC you can find detailed information about our company and activity on our website NEO NSPCC has been founded by — and experienced engineers with great technical background, and over the past five months we have put together a strong team capable to solve complex research and development tasks and have established several partners with different companies, universities, and communities We are a development storage platform integrated with NEO blockchain that allows users to store their data without the relyiance on a third party provider. Our goal is to provide users with full control of their data. According to development system of architecture of user controls, where is data stored and how, and who can get access to it NEO smart economy, storage, DApps, SMEs, and loT Use case in external use case, can secure a platform for storing data from DApps and final users. Minor modification s in the NEO protocol. We hope to discuss — it allow us to store data in our system for smart contracts, for example, in the blockchain we can store all block data in our system not but full — as in now. It can increase NEO blockchain activity All very good things. Our system is interesting for SMEs aspirate distributed storage and can store archived data in public storage. We are a flexible control system of storage policyies which I will discuss later We store data and distribute it through different devices. I will discuss about it To make our storage platform efficient in the use cases, we have set the following goals. In order to achieve the goals and solve the correspond ing problems, we have proposed a set of novel approaches and solutions. First of all, let’s see how the network is organized Three network node roles Host Host, publisher, and

client. Host is part of the network map, a set of knowledge about network and provides disaster for public sort. Publisher shows data in the network. Client is not a part of the network map and also not a part of accoun accounting system. Client can receive data from the network and in and out can combine different roles We have two layers of our network, inner and outer nodes Inner nodes are responsible forl maining accountability — to solve these protocol is used Information about outer ring nodes and network map with some additional information and they are responsible for keeping the map up to daddy and distribute it over all network Network map contains information about a group of nodes, their allocation and for correct data search and place ment. Bucket in our terms is a vertex of the grab and our system keeps the network map up-to-date and distributed over all network nodes. E-book is a time period when a network map is unchangeable. There is a demo you can find by the link on the slide. Instead of maintain ing a core database, information , additional information our system uses consistent placement function. We can place and get information to such party storing information and payer information. Doing so we don’t have to keep a huge amount of metainformation. How does it work? A user can define a storage policy by placement rule It consists of a set of applications replyied to the network map. The separations will be subject of the network map. A separation is applied to the network map. It takes input number of necessary buckets and bucket time. The separation take this this important information and forms sub graph and using for rendezvous and selective algorithm. If we select two locations sub graph will be selected by the high highest weight. In this example two buckets have been selected Separation inputs budget bucket type, bucket value and separation and we will get a sub graph. If you want to store data on SSD disk only you can sub graph will be selected which contains only buckets fulfill fulfilling the condition When the op patience operation of the next step will be performed for all buckets. For example, for the plac placement rule, when we want to store our data, disk in two different locations with three nodes in each location we can declare this placement rule as in the slide and one set of nodes will be accepted no matter who and where it performs the ap application. Absolutely any storage policy can be declared The store objects and work with them, we want to limit the sub graph on the network map in order to maintain scalability

This sub graph of the network map, in am ma zone, the closest is a bucket On this slide, container with two locations and two nodes in each location and redundancy factor per container is two Exactly the same placement rule is used to place an object in the container. Placement rule is applied to its placement in the graph Object intelligent device instead of container intelligent device. The result is consistent and placement group can do this without storing a huge amount of metainformation We have create add novel approach On this link you can find information about and we will announce our novel approach soon So we can put our get an object from the network and verify that the object is stored correctly. What will happen in case of nodes failing Storage nodes control the replication storage node yets availability of object replicas and where they are stored and that replication uses replacement function and ignores failing nodes, so same process as data replacement. This allows to allow our approach to scalable data placement, storage policy rule for object replaitment, allow minimal movement in case of storage node failures, so we are planning to support video from our system. About privacy In our systems data publisher is responsible for that encryption Control O. of encryption keys is assigned by the publisher. A principle task for us About payment, as a common solution of our storage, payment by guest token and based on NEO smart contract. It is controlled by inner link nodes and it can be used to convert payments into guest token so it would be possible for bank and Fiat and cryptocurrency for cost nodes We have a road map published on the website and planning to release the prototype of our system in the summer. So we are happy to hear your feedback regarding our project and develop development and also we are hope for open for discussion about potential clap collaborations. Thank you for your attention (applause) >> Thank you. So we have a slight change in the order. The next two squeakers are flipped flipped, so we have Liu Yongxin >> Liu Yongxin: Thank you everyone. I will share with you what NEO has achieveed over the past year

I founded NEL because my English is poor. Just kidding (laughter) Important reason. First technical Evan evangelism. I will elaborate on these points A QQ group with 1,000 people We also built a Chinese related technology exchange on the forum , and we held a series of face -to-face open con councils on related technology In the year 2018, we hosted the first new blockchain development competition. More than 100 team s registered and 40 games were submitted and 8 mayor 8 major games awar awarded. This has promoted new gaming infrastructure and technology infrastructure. In terms of infrastructure build building, we mainly develop the projects and we developed a high performance network databaseed called — and we developed multilanguage for interacting with new nodes and provided the rehappied API There are the API. I will highlight some of our projects. The first is light DB Transform the storage part of the NEO into network storage and the light node to directly find the network database to execute invoke script. Light DB is a modification based on the — it is difficult to understand what is the data presence At the same time different types of data are stored in different tables. Such as the transection s, Light DB is a da to storage location without having to go through the service layer and requiring firewall and data verification It makes the data synchronization very convenient This is Light DB makes it easy to develop in explorer and Dam

p. Let me introduce NEO Ray Integrate s deplete, compiling and debugging of the NEO smart contracts. NEO Ray is online version Here is a interface of the newest interface. On this page loin by line with line by line with excushion an execution to meet the requirements of debugging NEO name service. As of now they are already 25,000. We have gained a lot of value such as O3, SEA wallet , and others We assign a name to each new user, so that they can easily large. There will be more wallets in if future Do main names and holders can receive the dividend from the domain auction, and you can purchase in the second day market The first of three steps is applied to name service and the second is applied to other DApps and the other is based on diverseified DApps. It will be more stable because it’s not bound to one single DApps anymore Regarding the future plan of NEO Ray, chrome extension monitor, which will have the open APS to interact the monitor , and token ly token liquidity protocol — what is currently lacking in your ecosystem. Okay, I hope through the work of NEO Ray we can bring this one step closer to the users. Thank you (applause) >> Thank you very much. So one more talk and then we are going to have a little break. I would like to introduce Igor and vie tor Vitor Coelho (applause) >> Good morning everybody. Let’s do a double presentation, as usual >> As usual >> Here it is We are from Brazil. My brother is professor in the field of

computer science and we have been investigating during our life things related to optimization and high performance computing. Here it is >> So first of all, our presentation today is a more technical than usual, but still we are going to try to put this as easy as possible so for everybody to understand how is the security on the network and how the consensus works basically, and our perspectives on high performance improvements >> Perhaps some the difference between classic and modern cryptography. An example typical from one thousand years before was Caesar Cipher and he was trying to communicate and only wanted to wanted to make sure only his generals got the information The letter D to A scrambled in his manuscript and the few people that knew his logic could read his manuscript. Anybody who knows the roles can take his manuscript and decrypt it, so nowadays that we have computers, we have strong Erma sheen machines we cannot do such simple things. The most important things regarding cryptography is digital signatures. Usually we don’t do a lot of description of. Blockchain usually is digital signature and now we use this standard here, which is very secure for classic computer s Every type of cryptography depends on having a hard mathematical problem. Two problems here are integer factorization is like combining two numbers together to build a bigger number and trying to reverse this is really hard for classic computers and discrete logarithm. For classic computer s computers, now we are going to enter era of quantum commuter computers. They can do things that we couldn’t before. Is there problems much harder than this too? Well we have problems that are even more harder. Just to show how classic computers work. You have this shelf and our books organized, so I ask you the book R is here in this list yes or no? No. You can lock on the list but you can be smart and it’s organized after the P and before the Q Q, so more or less how computers do this minor search. Don’t need to look at all the data you can do like smart search Everything is scrambled, so the book R is here, but how can we make sure it’s not here, so have to look one by one to make sure it’s not there. How can you do this faster? It can be in any position. So this is what you call loin linear time. If you double the size of the input it will double the time to search Quan tom computers can do this search in the square root of this time It’s the So So for 100 books quantum computer would only need to look ten times and this changes how we do security. Integer factor factorization and factorization discrete logarithm become easy. We are on the road to build them. So in 1994, the algorithm which is quite similar guaranteed that we can really solve this problem, so these are

not hard anymore for quan tom computers to make sure our cryptography will be strong enough. Right now we don’t have quantum computers to solve this, but people perceive in ten yea years we will have Vitor Nazario Coeljo in 1963, some guys came and started to design things for complex optimization problems and base it on the nature, which is something that is natural to all of us because we imagined species and you are crossing and you can use that to find solutions that in each generation they are better than the previous one in the same way that species evolved so we like to show this example because it inspired a lot of different kind of metarisk. Simulated a search. That is this famous problem called eternity. In this problem we have a puzzle and each spes piece has four colors if you want to solve it with 16. There was a price of $1 million for who could solve this problem and anybody was able to solve it, but they thought maybe they designed a puzzle that is unsolvable unsolvable, but it is not. You can draw it in your home and cut the pieces yourself and you can see that after your shuffle that, you won’t be able to put the pieces together again , so that is our example of simple problems that are like finding specific ity in the universe. Igor Machado Coelho looks easy but it is hard. It is like a millennium prize problems People believe it’s different which means >> Vitor Nazario Coeljo: We believe this is a path for even a change in the way that we can mine hashes. We can have useful computation for solves these kinds of problems instead of just wasting energy to find a hash function to meet this, but this is another discussion >> There is a standard going on, and less than one month ago the report was relet ted with candidates for quantum security and one thing we need to worry when designing new cryptography is that is it strong enough because all the standards we have were tested for many years and there was a candidate like that was supposed to be strong and was patented, and after people discovered flaw s that could leak information, so it wasn’t secure. People argue now that one solution that we could adopt is like using two cryptographyies If it happens to be weak on the quantum side because it’s new, at least the classical part will be safe. Even if the quantum computers got accessible in the few years, we have time to make it safe at the same time Wes we don’t destroy the security that we have >> Vitor Nazario Coeljo: You can create a smart contract with a specific puz that needs to be solved and decrypted, but it’s going to be costly, so each time we want to design a specific cryptography we have two paths NEO VM, we give users flexibility to choose their own

cryptography. To allow users to pick their own and then this has a path of given flexibility and pass in this layer of safe to another level where users user it is user-specific >> Igor Machado Coelho: This is our vision that instead of bringing the full cryptography, just pieces that people can view view. For example, you can use bitcoin cryptography, just build the code like smart account contract and it works and you can build quantum security. We are in a few weeks I hope, going to finish up a prototype of quantum security and using the code we have, it will be costly, but it works, I hope >> Vitor Nazario Coeljo: In the white paper there was a proposal about NEO QS. In the white paper it was talking about two different problems, that is the shortest and closest vector problem which is going to have a space of integer numbers and want to find a vector that disclose enough to specific vector, but for example, you need to minimize the distance but you need a vector that is not zero, but reaches that criteria, that problem is hard to solve, but it was later show ed as we present presented in the last slide that was based on such concepts, so after you start to find a lot of different transactions, another idea came learning with errors. You have a space of integer numbers and you have a vector and you have also another vector of errors With both of them you have the prove key private key, so the idea is to play with these concepts for generating. There is a report going on about the N SA, and they are trying to pick the best safe forward for quantum safety. We keep studying that and keep connected with state of the art and think ing about good implementations and updates that should go on the protocol >> Igor Machado Coelho: We need four volunteers Because of time we have four trained volunteers. Usually like we need a multiple of three plus one, there is the rule to guarantee that you have resistance to one evil entity The evil is green here. So how the new consensus work, we have a speaker which is the node that is selected to proposal propose the transactions. This is this squeak speaker. The speaker proposeed a block so the others can follow the decisionment we don’t need all the signatures, but we need at least two F plus one meaning we are resistant to one fault. One fault there The network has seven nodes so we can resist your two faults This is a regular situation Another situation, it is not proposing the block in time The time passes and after the time passes the others request a change view, so that agree to change the speaker. So the speaker has changed. Now the speaker can propose the block and the others follow and we have a new block, so we are resistant to one fault fault Thanks This is like how consensus work but we have many options in improving the consensus >> Vitor Nazario Coeljo: This was a die Didactic example. When they were praising

raising their raids hand we don’t want to expose that because it is exposing your signature We want it to be redundant, and recovered, and we want it to be resistant to hardware female fails. Now we are calls dBFT2. The first one was proposeed in 2014, 2015. In a couple of months we could have a second version of that considering these papers that have been done in the literature. We have different ideas Something for perspective it has not been easy. We have block finality in the really of con sense sus itself, we don’t have block finality in the really of nodes. nod level of nodes That is not easy to achieve They check if more than one consensus is sending the same block. When you have block finality in the census layer that means from the consensus below it, we can never send two signage blocks and that is a channel challenging and very useful feature. If we keep this idea of keeping the consensus in that level of block finality, and we have also for that the perspective is that we can break partial sin kronicity synchronicity. In a specific time we should time out then We cannot wait infinitely so we believe that recover mechanism SSP something that could break and partial synchrony having new consensus. The the consensus is able to be adopted we just need to change the way that each of the nodes are sign signing and communicating between them >> Igor Machado Coelho: Another thing we do is dealing with high performance computing and the conclusion is we all have a supercomputer now. Like smartphones today is much more powerful than the top super computer 20 years ago. We have geo computing and different hardware that can be explored to improve the speed of the network and the processing of the network. We did experience on elliptic curves done on G.Us which are faster processors are parallel data. We could calculate more than one million signatures per second, which is much more than the network needs and the in terms of cryptography and the network could do many other things, storage, and other types of calculation, but still we have many tools to make the network must faster, so it’s possible to improve a lot. This is a picture of the guide that did the experiments, and that is it. Thanks to all our volunteer s (applause) >> Thank you >> So we are running early, I can’t imagine that actually happening at an event, that almost never happens, but the food is ready. We will take our break now and we will be back in about 20 minutes. We will see everybody at 5 to 11:00 Thank very much >> It’s important to consider the security of a

project from the beginning

If you are going to build a NEO smart contract or blockchain or

any kind of project, security must be an important factor to

keep in mind when you are start Agnew development process

>> Talking about security practices, one of the most

important aspects in secure development is to verify all the possible inputs and return value s Which is important to know which information we will receive and how we should treat it and very important to perform unit testing so make sure that all the code works as suspected Equally important is to perform unit tests for cases that are not expected. For example, if you have a smart contract that has a transfer function that you receive a 20 address Lent, important to analyze what would ap happen if it receives a 10 byes 10 byte analysis length. This is a way to know what vulnerabilityies appear in a project. It is important to perform tasks in a real environment, for example private. It is very easy to set up a controlled environment using docker. This will help us with compilers and operational filers. Do not forget in a project that uses a third party library, this also should be updated periodically. If your project requires cryptographic function, we must analyze it and see what information is more secure and more reliable >> Now we are going to

show you public examples that you may know. Example of what we have seen in our security audits. The first example is a bug that procowsed one extra argument proproduced one extra bub from exextra bug from the stack Here in this slide, you can see the technicality of the bug in case someone wants to investigate more about it >> Okay, another common case last year ether eth theorem abinexpersonsed developer costed a loss of $300 million. This is an error that could have been avoided by following good practices because they didn’t utilize a library that was initial initialized by the contract. The developer dezoid ed to initialize it and became the owner of the library contract. Once the user one the owner of the contract he had the mistake to call the kill function and all the contracts that were using this library was gone and their balances were gone forever >> In this case, the CEO unfortunately died He didn’t have a multisign wallet, and all of the customers meres were lost and the company closed. Now we are going to see the storage of — this is what we found in implementations in NEO. In the case of NEO it is important to know that storm works as key value, so if you are able to control the key you are able to write in any place of the storage and compromise the smart contract. in this code you can see the parameter is not controlled. You can see the parameter so used key as written to the storage without being validated. The correct way would be to check the input to en ensure that it fits the entire format and another good practice is to use a storage map It is a function which is assigned to avoid this kind of failures. A problem that is also seen very often is the use of hard coded variables on administrator accounts that would not be modified. What would happen in case you would have to remove one of the admin strays or revoke one of his permissions. We must prevent these situations as we saw in the case of the CEO who died Not everything is blockchain When we out did any project we recommend to our clients to perform penetration testings over assets. In some websites and services that we have been auditing in the last year and we have a lot of experience in performing this kind of test All the examples you will see now are real and found in the projects we were doings have year and of course all these vulnerabilityies have been solved. The first one is STMH This allows us them to sandfishing campaigns In this issue the issues was locate intelligent device on the one functionalities of their

main well well, a website subscription functionality. If we were able to send any e-mail to servers using the e-mail serveer of the company. This would least to loss of fund or at least loss of reputation This will allow us to modify functionality of the users or for example, modify their token balance. We were able to modify the token balance that appears in the token distribution platform used by the client. By just mod modifying their — request and parameters as we were talking previously Another common July vulnerability is SQL statements Depending on the database configuration we can also modify the information that is stored in database or even gain full control of the systems. Of course we can also see all the personal information of the users and modify whatever we want. As we can see to test this vulnerability, we just modifyied the request and tried to execute a sleep of five second over the server. If you look at the response, you can see how the server takes five seconds to respond. This is just like a proof of concept that we used to test that the server was ver vulnerable to SQL. Another one that we will see today is cross-site script ing He will automatically send us the code via the authorization cookie. This is something we tested with own of our clients and this is evidence that we prepared of how we received the administrator cookie when the malicious code is executed With this cookie we can log into the application as if we were the administrator This is the last vulnerability we will show you today This main one is the to force the using to use one — in the web application. For example, in this case we were able to prepare a request that modifyies the address or password when used by user or admin. This is the end of our presentation. I know that was very brie brief, but hope you liked it and thank you very much for your attention >> Thanks, guys. Next up as we continue our deep dive We have a panel to talk about user experience and security enhance enhancements of neo wallets. Our pan lists are coming up Nicholas Merten is our moderator Give these guys a round of (applause) As they perform manual labor >> Just a real quick introduction. My name is Nicholas Mert Merten. I run data dash. I love learning what

is going on in the tools that we are using for cryptocurrencies We have Maxwell Lapsky, Alex Knight, and Alex DiCarlo. Three developers working in different projects like the the neowallet The first thing I mentioned was user experience and the problem I find a lot is most wallets over the past decade has been QT wallets, very inefficient to work with, and something that I don’t think we can see 99% of the world that haven’t adopted cryptocurrencies using. What are you working on at the moment to better user experience and better simplify the process? I think in general often we get pretty wrapped up in the applications that we are build ing, but unrelated to blockchain , I think it’s important to step out of that role and just think about interfacing with the application with someone for lack of a better word is a total idiot. It goes a long way and kind of just interfacing with DApps and to neowallet. I took a look at it and I thought there was a lot of things that could be done to the app to make it more user friend friendly, and that has been my vision for the past year -and-a-half or so. You lock look at applications like — and it is the most popular one used today and it is confusing even coming from someone that knows a lot about NEO and blockchain in general and look at the app through the ey eyes of someone who has no excue at all, and I think that has been a proven and sound technique >> Nicholas Merten: Alex , what about you? >> Alex Knight: We released it over a year ago, but we haven’t made too much updates, but we are working on a full redesign We are really focused on making it super simple to uses. Today when you go to NEO tracker if you have no cryptic experience. You would go to NEO tracker and see this page of like a blockchain explorer and log in with your private key and it’s not very friendly and people don’t understand what’s going on there What we are trying to do is to echo what max is saying is if now have experience, you can come to NEO tracker and leadership about blockchain and how well it works and get comfortable with using the wallet. Some of the things that we are experimenting with is to make it so that you are comfortable with transferring your fund. I think one of the things that scares people the most object using about using their wallet is the active transferring fund. It’s a very daunting task because you are like if I mess up, this is it, I lose my funds forever, so we want to make that process more seamless so that you are more comfortable with transferring found so every time you need to transfer to an app, you are not feeling like this anxiety that you are about to lose your money. That is one of the things that we are working on in the redesign >> Nicholas Merten: Does your wallet allow for contacts or being able to list an address, like by Bin as address >> Alex Knight: Making it we can integrate with exchanges rather than going to your exchange and say let me copy my address, just have it transfer to my account that I have already prelinked with my wallet. I think that would be interesting to pursue and something that we will look at in the near future. The knee

tracker wall eat is something that is old and redesign is what we are work oging on >> Nicholas Merten: Even just the simple copying and paste pasting I find myself double checking the address and that can be daunting >> We are always trying to improve and remove the technical jargon that people who don’t use these sorts of wallets might be uncomfortable with. We are looking at having better on- on-ramps. We have released a cryptoswap. It’s all integrated to Zhao don’t have to worry about it, you send bitcoin and it will pop up there. We are working on improving the developer experience, so we have released API for developers who don’t know much about blockchain or how it works so they can integrate their apps without that knowledge and they can just basically use our wallet as a gateway to make payments and sign contracts and things like that, so that is a big part of getting new developer developers into the space without needing to have the technical knowledge to do it >> Nicholas Merten: I was fortunate to go around the boot boothings at the conference , I was watching the employees show showing off the 03 wallet This is something that I am curious about and want to get opinion on what you are doing I saw in the 03 wallet, not doing you not have to manage a lot of technical jargon, but within the wallet with the applications, I could instantly start swapping knee token sey swappingee token swapping NEO tokens — so I would love to hear from you, you talked a little bit on the 03 platform are you doing anything as well in that regard with the NEO wallet >> Alex Knight: I think what 03 is doing is really great Something for a long time I push ed for is that decentralized app apps should not also be wallets It makes no sense. If I am work ing with ten different apps, I shouldn’t have ten different wallets. I have to trust ten different places with my prove private key, that is crazy What 03 is doing is something that we have been wanting to do for a long time, is a way to integrate with apps is something that was a core tenet of another product that we are working on called NEO 1, it’s a development platform. The way you work with NEO 1 in such a way that you end never createing a wallet. By default it integrates with deferent wallets and you shouldn’t be createing a wallet as part of your application so I feel it’s critical something we are doing with NEO 1 as well as NEO tracker >> Nicholas Merten: We have been hering hearing store story stories — it tur turns up most people report bugs to the team off bug bounties on wallets given out before they become issues to others. What have you en you have been doing on the side of security and new areas to improve security on the exist ing wallets that that you are working on >> Maxwell Lapsky: I am sure NEO tracker and securityies as well, it is at the forefront of everything that we do. We definitely take security extreme ly seriously. Recently before the launch of V2 of NEO wallet, we had a rigorous audit on the entire application top-down by a cryptosecure firm in Germany, A Acure53. Our manual test

basically covered all of the issues that we had before, but that really thorough audit did expose some minor issues that we were able to cover up, but basically when we take on new feature work it’s at the forefront of what we do, and we have a pretty large automateed test southeast as well as rigorous manual QA process before we put out any release and before we put the wallet out in front of consumers >> Alex Knight: I think for right now we support a few ways to dog into the log into the wallet. A plain encrypted prove key. In th private key. In the redesign we are going to try to reduce — let me take a step back, the main way peopleize people lose their funds is they get fished and they go to a side and end up entering their private key that they shouldn’t have. We almost want to make it so our users can’t make that mistake, so exmerrimenting with different log in experiences and registering and people log in with e-mail and password and maybe adding a layer of 2fac on top of that. We are not going to be an exchange where we own the private key, we are going to hold the private key for them in an encrepted form so there is less of a chance that they could take the private key and put it somewhere they shouldn’t >> Nicholas Merten: If I gate right same scenario , what you can do is by building a log in system by then plugs in the correct log in information they could access a file where their operate key is storeed in their device, but it’s an encrypted way way, sumphishing site would not know how to access that information >> Alex Knight: Similar to, effect effectively kind of like an encrypt encrypted develop box service that they can only access with log in and e-mail password >> Nicholas Merten: That sounds good >> Alex Knight: We offer backup options with the encrypt ed version where they can keep it on the computer or something like that, but also we offer these services that you can connect to without needing your private ke key to con NTSB it, so the service would send you a raw transaction where it would be signed into the wallet and returned to the private service so the prove key is never ex posed to other services so when you are trading you don’t need to access your prove private key >> Nicholas Merten: So its all done in the wallet, interesting. A lot of interesting things. One thing I am curious to talk about is with the standard for tokens coming ou out, a lot of people are talk ing about nonfundable tokens NEO is focused on building a digital economy. Are you goys optimistic for the potential of nonfundable tokens and do you think it will play a role of what is stored on these digital wallets >> Maxwell Lapsky: I can’t see that we are actively developing futures to incorporate them, but in general they have a huge potential feature in the NEO blockchain I think the thing that comes up for me time and time again, is there potential application in gaming where we can have multiple applications interfacing with the same NFTs and rendering them in different context, and I think gaming is

something where unique, digital things of value happen time and time again, so it’s not a very specific answer, but in general the digital scarcity that NFTs proride provide has a huge potential >> Alex DiCarlo: At NEO tracker we thinking along the same lines and watching the space closely and see what NFTs start to pop up, but as soon as we see the standard finalized and NFTs start to pop up, we will support them within the NEO tracker wallet >> Maxwell Lapsky: We are pretty >> Alex Knight: We are pretty much on the same level and we are exciteed to get something happening. One thing about the NFT NFTs too it is an interesting design problem because your wallet is going to be full of lots of stuff potential so we need to figure out how to show those in different stats where you have one for each project so that is one we are thinking about heavily but still haven’t put anything together >> Nicholas Merten: One good last question and I would like to get an pen opinion from each of you guys on this one. I would say that 90 to 95 percent of users and less than 1% of global adoption of the world that own cryptokeep their money on ex exchanging exchanges Right now you are focusing on building the wallet experiences For someone like me that got on cryptofor the ability to own your own bank. Do you feel in the future more and more people will want to own their own bank What are you doing to make the ultimate change that will lead the other 90% of the world to becoming their own bank in that case? >> Maxwell Lapsky: A lot of people are willing to invest in blockchain but then not willing to use the technology It is the antithesis of the en tire thing that we are trying to do, so I think driving people towards trusting the ownership of their assets and prove sees is super important, and it can be achieveed through IU and front-end development that is self-explanatory and easy to interface with and just really straightforward, so that is something that the NEO wallet team is going to keep harp harping on and driving towards and hopefully keep increasing adoption and having people trust themselves is our goal >> Alex DiCarlo: I think it is an interesting issues with the exchanges and that really what it comes down to is users, it’s almost too much responsibility to be their own bank current currently and what we need to do with UI and design and wall let lets is make sure that they have less responsibility, less of a big leap. Today its a big leap to go from my bank that I trust and if something goes wrong I can call them and they will probably get it reversed whereas today if it goes wrong, there is no reverse. If I lose my private keys, there is no reversing it, so there is this huge responsibility gap between trust ing a third party to kind of handle things for you, and like trusting they will probably be able to reverse things if they go wrong, versus doing it all yourself and we need to bridge that gap making people more comfortable comfortable with being their own bank >> Alex Knight: I think I reflect exact think same. It’s about safety of losing your private keys and not being able to access your fund too much anymore is just too much responsibility especially if they have a lot of money in therem there, and everyday time people don’t want to think about this thing, so we need to have a way to find fullbacks for situations. I don’t know what that is yet. I think we will

see companies build these new services that will help you manage your tripe crypto. At this point it’s still a bit too dangerous for most to deal with that responsibility and would rather pay the $5 a month for the bank to look after it and deal with it all, so that is something that we have to do a lot of work on to make it more mainstream >> Nicholas Merten: I wish you all the best of luck I hope you can take that challenge on and make it better working with exchanging and above all build a good user experience. I have used neon tracker and you are doing good stuff. Thanks for taking the time to speak. Appreciate it >> Thanks everyone (applause) >> So I have a few T-shirts here I have been told they need to be thrown into the crowd. I’ll see if I can do a better job of this than I did yesterday Slightly better. There are more for later I would like to invite Dr. Junda Liu Give him a round of applause >> Dr. Junda Liu: You may have heard about this different terms of chain and layer two, channels, generic channels We might need a blockchain for a consensus on the term, but on a high level, what is the Celer network. We consider it more like coherent off-chain platform with the primary target on scale scalability, and the scalability has two parts of the problem that we are going to go into more details later. There is a layer between the underlying blockchain and the applications But why we need it? The blockchain has been pretty good If you want to do something with what we call layer 2 state channel of development, it has been available for a while and there are already very exciting projects based on, built on top of that. It’s available native ly, mobile, Android, iOS and web. Has been doing part of the application for user s and the other part is trying to form this layer 2 standard ization body, so basically we work with all the different projects in the same directions that instead of everyone making your own design proposal, how about we come together. We have a weekly call on that about generic state channels and we have the virtual list together to go over what should be the interface and what is the trade off between the security and performance. What is the best user experience. We work with several projects in Europe This is kind of what we have been as part of the fundraising and technical partnership we have been working with different teams and different public blockchain and we are in the middle as a new platform, so we have to work with different blockchain projectses, and other applications at the same time on top of that The blockchain I remember hearing somebody was asking why he fells it’s a little bit confusing and more people would invest in this thing rather than using it Our own view of the information in information transfer Imagine just a hundred years ago you want to send a message to someone else across the world, how long would it take? How

long expensive it has to be, pigeons, postman, whatever, but now with internet it’s instant, almost close to light of speed, and also it’s more like a stream streaming experience instead of every individual chunked up envelope, you have screaming across scream streaming across the world instantly. Same thing could happen with value transfer How about we target 500MTPS. On blockchain alone this can never happen. Imagine the physics. It’s not about technology. Can a public blockchain support this number? The answer is no, so that is why we say solution has it’s value for mass adoption and part of it is for the raw TPS and the other part is for the latency, so for err every fully decentralization decentralized blockchain, there could be people overriding the different blocks and you could run into the risk of duplicate translation in different blocks If you ask the user to wait, the user is used to the internet latency. When doing a Google search if you tell me come back in ten minutes, it would never work. The latency part is also key for aoption Off chain can solve this. On a high level it’s pretty simple and you can find similar idea in real life. Before the off-chain payment channel can happen, there , Alice and Bob deposit ten token into this smart contract After this, what can happen? They can effectively only between them send back and forth off off-chain transactions without any commitment needed from the blockchain. You get this instant finality. The moment I send it to you and you sign it and get the transaction back, and it is fine. For all the finished. For payment alone, it’s just like how many money I owe you and how much you owe me In the beginning each deposit 10 Drs. In the end, it could be millions of whatever or trillion s of transactions between them back and forth, but in the end the only thing that matters to the off-chain contract is what is the final number that Alice and Bob should have. In this case after 47 transactions, Alice said this is our latest result between me and Bob. This is the token distribution fate fates First thing is to set up the channel. One of them will say this is our latest distribution of what should be sent to me and to the other party, and in this case let’s say Bob degree agrees which is the right balance on whatever they agreeed upon. What if one party tried to play with the system? What if they tried to submit something incorrect, or not exactly incorrect but intentionally submitted submitting outdated agreement, what can the other party do? Using same example when Alice was submitting 47, actually bob has newer proof between them saying Alice should on the get 2 and Bob should get 18, so the smart account has this logic to say whichever is the latest take s the priority

You could have malicious user try to submit outdated proof, as long as the other users have the newest proof, and can submit to make sure there is no security sacrifice. In this case, the contract will always be follow ing whatever is the latest agreement between the parties This construct can be extended to the network. Another problem initially people say before I even want to have a transaction with some other random address, do I have to always set up a channel with it? No, because with some term call called hash time lock, in general hash lock you could send up the path as long as there is a source between you and the final destination. A path to a network. That is base collthat basically what it started as payment-focused lay 2 network, hub-to-hub payment channel and when ever you send something it will be related by the node in the middle. Does it solve all the problems? The short answer is it is a ways from done There is some security channels that we have to handle in off- chain. If it’s payment only it’s still missing the power of smart accounts. Saying I am trying to dopa DApps develop a DApps game. If you ask someone to play, imagine how long that would take It is slow and every single move would cost you traunch fee Codes are relaying all the payments, what would be the reasonable incentive, and what is the problem for so, I have to to pay a fee per hop fee per hop. Just by doing off- chain alone it solves some of the problem, yes, but it also has it’s own set of problem because the — was started to say off-chain is the right direction to cut down the latency and also improve the scaleability in terms of TPS, but at the same time we are not claiming it’s the holy grail and solves everything by itself, so we see new problems arise by chooses this direction and also to see what is the right solution for new problems The example earlier I gave is two parties agree on a number, and now you can say, what if this number can be something arbitrary. Say, just like a less board. chess board There are many smart accounts that implement this on-chain games, but of course the user would be very small because imagine every single move. You have to wait for the move to be confirmed by the blockchain. In the end, hopefully when they are both still alive you can get the result of the game and let’s say one party wins, but the user experience many of the panelists talk about this a lot earlier You could say the users have been spoiled by the internet, right? Actually we have done some user study and even if you show a spinning wheel the user is likely to quit your app Every single move I have to wait for the spinning while. Again with wheel. In the beginning of the game there is a powerful construct we call conditional payment, so if you go back to the original all the payment happens in lighting network, it solves the payment itself which should only happy, let

only happen, say you buying coffee and then you send payment. I am sending the payment right now, but this payment cannot happen until the attached condition is true, so this is what gen generic state channel with label. In the beginning of the game both parties say I will pay this amount of stake if you win Alice says to Bob $5 if you win and bob of course sends one to Alice saying if you win, you will take my money. At this time, neither party can actually take away the payment because the condition by itself is false Then this comes just like the earlier off-chain payment, the off-chain back in the force saying this is my move and this is your move back and forth The latency and commitment happens instantly between both parties and nothing needed for blockchain to confirm Let’s say the game ends and Alice one, now the seller network enabled is kind of when do you resolve a condition This is a virtual contract and it’s not even deployed on a blockchain, so there is the off -chain message in protocol that says when the condition is true we can confirm the payment Remember there was another payment from Alice to Bob, that payment condition would be false , so the payment is canceled Nothing like rocket sign, but en ables us to say it could be an arbitrary action state. We have interesting projects based on some Oracle tol say I am doing streaming payment for a subscription, so every second I am sending you a payment with the condition your service is up As long as your service is not up, the payment itself is invalid, so all of these things can be enabled by conditional payment Now the c economy part. We talk about about the benefit of off- off-chain. We put too much burden on user. Not only do they have to manage their private key and also be aware that at any moment someone that has played a game with me sudden ly wants to dispute, I need to react or what if I am traveling in the forest or I want to — to solve the centralization risk showing to the people that it will be more and more central >> Dr. Junda Liu: Ed season trallize centralized. As long as you are comfortable to run a node you can get what you need What if myself is going offline and basically disconnect from the internet, and at the same time what if my county party tried to submit earlier state proof that was benefit to them and actually would hurt me, I have the latest proof, but I do not have the opportunity to submit it to the blockchain, so I would loose and this is where we would have a special — guard your state If you know you are traveling and won’t have internet, you tell the state guardian, this is my state. Help me to sub submit if needed for two days. This actually goys the time ly goes actually goes by the time time. They will have the

probability to do the work for you based on their seller tokens In this case, if someone states a little bit, they will be more likely to be chosen, yes , number 2 you will take care of Bob cease’s state proof. If anybody tries to submit incorrect one, it’s your responsibility to submit what Bob told you. There is this penalty mechanism a little bit like the POS mechanism, so if you didn’t do your work, your deposit will be basically crash ed A seller token translates to in a state guardian network to user income flow. This is my willingness to pay you if you do the work What is picked is based on the state CELR token. You can say I will be back in two hours so only need the state CELR to forward for like two hours How do you optimize the payment routing and the new word is different from the public blockchain to so we have but the layer to itself has its own set of problems. For anyone you are welcome to check out our website s and white paper we can discuss offline. Thank. + >> We have one more presentation before we break for lumping lumping. I would like to bring to the stage Fu Xiang He is the architect on chain Please give him a round of applause (applause) >> Fu Xiang. : Hello everyone. First of all, what is ONI? It is independent protocol layer between the application and the — we use it to build up platform to decentralize the storage and the sharing service In my opinion, most of the blockchain of the word can use this platform to serve their user and the user don’t need to exchange token or coins and they don’t need to know how many nodes on the surface and which consensus is use using. They are just protocol API directing one advantage is structure Therefore several problems in this environment. There are Privacy security is being channeled all the time. If the people have the same poppy right data they can copy the data and share it to each other For a service provider, if you want a better user experience you should buy expensive hardware, software, and network bandwidth different application providers require redundant storage and

CDN for the same copyright content. Which benefit can we earn from this OMI protocols? First of all the data for storageing the networks and people can decide no host server and data is shared at high speed between the loT device devices. Transaction fee can be paid automatically to copyright owner and last one is user can benefit from sharing downloaded data and apps reduce storm and storage and network bandwidth The next question is why is layer2 based protocol only layer of the platform. and have many different blockchains and different consensus , different confirmation time, different gaps gaps, but all are used to send protocol AP I and the layer 2 is the only platform. It will provide decentralized storage to other blockchain and it’s using the cross-happy protocol to manage pub-chains For the application layer, the faster data transfer and the transaction confirmation improve s the user experience and the uniform decentralized access pro coland multiple token interface interface much easier and pay data sharing service will more quickly and zero transaction fee will encourage use enter in different blockchain economy. I will introduce the ONI frameworks what can we get from these frameworks? We will provide SDKs , we will give you browser, DNS node, FS node, wallet, and other s use need to integrate into this platform. Now I will explain how the O (I platform works. For these networks there are several nodes which we call decentralized storage for these networks. It provides data slicing and redundant storage. It is also using up PD P to check if data are stored in different. If S nodes and different FS node It also has the content contract property tol contract protocol. Along with this, we will set up a knew network few networks which we call decentralized networks. We

will have P2P sharing information between the clients and FS node and the state channel we will be running on these networks and DNS and route proxy and stuff like this, which makes running on these networks quickly and smart Next, I will give you a steps to show how the sharing stuff is running. At first, the client will set up and it will connect to the dns node, then we will create a safe change between open other, and then the clients will send the request refor DNS node. Maybe get from website or any social network The DNS node will be translated URL to the hash screen in pairs including the FS node Then they will hand shape with each other and begin to transform the data slice After clients receive the first data slice, it will push the slights slice information to DNS nodes and helps client receive slice push info to dns or wait for other clients Now we have done the PDP algorithm, the P2P module, the smart contract, and we want to test on it at the end of last month. Also, at the end of Q2, we will start to open source and I believe that more public blockchains will join in this and that we will start to copyright contract, and at the end of Q3, Q3 — will be released and the more bub public blockchain will join in this and we will — the DNS. That is all. Thank you for your attention. Thank you (applause) >> So with that, we are at lunch and we are running a little bit ahead of SQL, so I don’t thinks the quite set up out there. We will be back here in the main room here at 1:30, and I will sea you see you then. There will be T-shirts given out then, so make sure you come back on time >> Okay, I hope essential had everybody had a good lunch

We have a few T-shirts to toss into the audience

Where you know without further adieu I would like to bring up

Fabio Canesin. I am beginning to mess up your name. He is the

cofounder of city of Zion and Nash. The morning was all about

blockchain deep dive and this afternoon we are talking about

DAppss practices and patterns (applause)

Fabio Canesin

>> Fabio Canesin: It’s great to be here one year after

we started everything in San Francisco, that was the first

event of NEO U.S., so a long journey and so happy to be here

again. I want to talk about distributing finance to everyone

here. Everybody knows that both from city of Zy yon and

Nash we have been driving this different way of thinking about

blockchain, so we are trying to take it from a business

perspective where blockchain is the business structure where we

build this financial system of the future, so we believe that

blockchain is going to be the infrastructure for digital asset s and the way we go forward on society is increasing how society is digital I want to talk about Nash for you guys and what is actually is because there is a lot of confusion talking about Nash is an exchange but it is a financial platform for the future when the economyies are digitalized. NEO is a great partner because NEO is a great about a smart economy. The first thing is most people are already familiar with our project called NEO exchange which it has the token NEX. We did a re-brand, but came the name for the token. We have a new brand. We have a new look and feel that I think is great Nash is going after one major problem of cryptocurrencies. If this is going to be the background of the economy, we need to solve the problem of self-custody 99% of cryptocurrency training takes place on centralized ex changes and your assets on these exchanges are not crypto anymore but mere representation of what cryptois. We wanted you to be able to still use your fund while still being in

crypto. We need a DEX if we are going to be able to get there, we need to be able to trade assets. Next is an exchange where users are in control of their assets at all times. It offers the same user experience as the best central Lized experiences. Everybody today has some banking app, maybe Venn mo Vemnmo or whatever There is a lot of promises and it is very hard to achieve, so how do we get there? We get there with revolutionary UI. To do revolutionary UI, you need revolutionary technology. It is based on what we call off-chain and on-chain. What does off- off-chain mean. Means some computation, the matching outside the chains but we need to assign contracts and do hand shakes in the platforms that people hold their assets. This is deemployed in NEO and bitcoin and elsewhere, so this contract descriptions hold the state channel system with matching managers and interactive user wallets. I’m going to show you guys what is revolution ref rev revolutionary for DEX and for wallet. This will be on going security tests now and for a while. These are new protocols. We are not talking about just one, but about one for state channel math, for zero management of keys and one protocol for interacting with the case management to the state channel management. To be secure of it, we need to have many testings. User testing is more regarding UI and UX. We have always been saying that next that we will launcher when we are happy with the interchange and how can we say that we are happy with the users are not using it, so that is why we want to get more passionate users, so some very wise business people said you need to find passionate users about your product and listen to them, and that is what we want to do. Revolution air Revolutionary UI, if you think about the best systems that are centralized They look exactly like this and that is what we want and we want to push forward. You are a website that you are logs in with your e-mail and password and through a complicated management you get yourcos from your client and it looks like you are logging into any centralized service that you know. After that you have your wall let here for bitcoin and NEO and wallet and what we want to support in the future that you can manage your transaction s, see your assets and manage your coin coins. The technology behind the protocols are there, implemented and solid, but we want to work with the users how this is beginning to lock like and this is how an inveigh invasive ex exchange at Nash looks like. You have a very fast interface and you can do cross chain chain as if you are doing it in a centralized ex change. You are trading F for F and F for NEO as if nothing was holding you back. How do we do that? Using state channels This is how we are going to buy

crypto Partners are behind clear and they are deemploying to the client. Our client is coded as adversarial, so they don’t no trust where they are sending from the front end This is something that we haven’t seen done in this place A great wallet for funds math, a great exchange for trading and a great way to go in and out of crypto. They are ready for launch on March 31 (applause) We invite every member on your community to trade, pay, invest, in many chain and cross-chain with no latency. Our goal is to provide revolutionary UI and we continue to strive with technology how to get there and how to bring everybody to a digital economy. If we move forward in this future, how people are going to interact with digital assets should be as natural as using centralized service today. I am very happy that we are going to support U.S. at launch. I am Brazilian, and I can say this, U.S. is not going to win a Brazilian bureaucracy. I know bureaucracy , I can play that game. So we have the licenses for material loy sense licenses in every state and we are going after every license to allow us to do the user experience we want to provide. We are not only follow ing compliance, we want to push it forward, so same way we worked with the European union to launch the first public offering of a security token We want to help every other place that we work to have more forward-thinking digital economy launch This is how Nash is going to look like and this is how Nash is looking like now. This is just the launch of our NEO UI or how our brain looks like. You can enter gnash I have to thank the team on their amazing innovation We are going to give away 100,000 in bitcoin and 46,000 Nash tones. Turing is easy. You need to have a referral code and this is by invite only until we open it to everyone. To wait on the referral code you can use one of the cards that we are contributing distributing here and it has a code on the back, or you can be a member of our community where we will send a message with a code for your to join our referral program. I want to show a video (applause) Yeah The more people you invite to be part of the digital revolution the better we are. We want to continue to work together with the community to refine the project and continue to work with the community to give the most value we can to our investors. Nash loves developer s. We have dev. con. I need to

have a few slides about developers. Everybody knows that the five founders of Nash came from city of Zion. We tried to put a lot of code up in neon Python and neon wallet, so we continue to love developer s. We are developers at heart, so to be developers at heart we want to provide the best user experience for developers also It is not enough for us that the user has the best user experience when we trades — we also want that people who build on top of platform have the best tools to build also. Three Ex change made by three complex protocols is as easy as coding any centralized servers. So you can easily port your current to it. Web prosecute voiding Python SDQ, go SDK, and type script SDQ. We knee you as a Python developer that Python is API, I will show why This is a graph dealing with three complex things to list all the balances in your account With ten lines of code code, six of those comments and definition you can list all your assets in five different chains in a decentralized manner manner That’s how you bring best user experience with developers and that will be launched on March 31. We are going to open source preSDKs for everyone. Thank you very much (applause) >> Thank you very much We have a video coming up next are Steven and Alex the CEO and CTO from bridge protocol Identity is what makes us all unique from the way we shop, travel, and connect with the world around us. It allows us to identify with one another and maneuver through both physical and digital worlds, however this interconnectivity comes with its own set of challenges. People no longer have control over their sensitive information The more data we share, the less control we have over it. We no longer get to decide who sees or profits from it, and that opens the door for bad actors. Our identity is our unique DNA It’s what sets us apart from one another, but in this digital world, our identityies are more vulnerable than ever. We regularly disclose more information than we need to for services that we deem free These services can come at a very high cost, but luckily bridge protocol strives to reduce this cost createing a world where you decide who sew sees your data and you determine the data you want to be seen. A world where you control your identity. Bridge protocol is the future of digital identity Utilizing blockchain technology, bridge’s safe and secure identity verification for users and businesses alike. Users can digitize their identity with the bridge passport without having to share sensitive information Keeping your sensitive information securely off off the blockchain and establishing point points of trust for the user and the business. Preserve ing anonymity. Bridge delivers comprehensive compliance checks through trusted verifyiers. The bridge extension allows users to send their NEO address along with their verifyied identity

ensuring businesses get what they need to be client and nothing more. Take control of your identity. Bridge identity secureed >> Can you hear me? How is everybody doing. I am Stephen Hyduchak and I’m here with Alex Guba he is our CTO Hopefully we won’t bore you too much. NEO is throws a great throwing a great event. We drank lots of Starbucks and tried those new Seattle hot dog dogs and that was pretty cool too. The first thing we wanted to tackle was the blockchain development. When wu pull that back, that is where is the problem and we saw the traditional KYC and it was expensive $2 up to $60 for credit investor checks. That is what you are see you are snig the STOs now. It limbs this whole space on what it was supposed to do. This is one of the things we wanted to tackle with this solution. It’s a compliance tool out of the box That means the business doesn’t have to go in and try to figure outdo I need this watch list or do I need to certify this passport, how do I do this credit investor check and it’s already done for them and ex plained easily. With our system the users only verify once, but I’m sure we have all been there, multiple exchanges, send your passport with a selfie. By doing this one time through a trusted party, it elem Nate Nate elimb eliminates that element There has been transaction additional securityies regulation and financial instruments that need these things. We are just standard izing that and that means we found that a croak extension regardless ex chrome extension no matter what you are using — businesses are coming to us and saying what do we need. Do we do a regular D or regS credit investor investors. How do I certify the documents. We need a streamline to do that. Do I need facial recognition? What is a due diligence and those are seeing that out of the box. There is a business need, so we are see ing a lot of different companies come in with social media scoring, transaction history intelligent device, companies like chain analysis will track them, blacklist them white list them, but the social media scoring is in my opinion not a good way tooidfy to to identify someone. There is a lot of bots on linked in and Twitter and you need a safer on boarder to bring them into the digital world We here there is multiple dock trends and it is expensive and that is one of the things with the blockchain identity and the way we architected this, the business doesn’t need to worry about G.DR. When we use bridge we shift the power back to the user, once your idea is scour secured you go through the process and you get a bring passport and you get these claim s that allows them to say hey, I can control my identity that ex exchange doesn’t hold that information anymore and that means you don’t need to deal with regulators hitting you with a big fee. The cost is almost three times as much to be out of compliance than in compliance That will give them the tools to say hey, if easier and cheaper, we will hit it from the get-go

>> Alex Guba: There is three elements of the bridge protocol network. When we are talking about identity, our identity is made up of a collection of claims around us Are we over 18, what is our name and what is our Social Security number. These are for peer -to-peer fashion. It’s also a network of trusted partners on the bridge protocol network we are verifying that when you go to submit those claims about yourself you know who you are submitting them to. It’s a data verifycation market plic Verifyiers want different types of information. Third parties can offer your services on the bridge protocol network for a fee to extend the marketplace and extend the things you can put in a passport and build out the ecosystem. We have decided on a web brower browser ex tension based interface that will allow uses with no ripe cryptoexperience to take l take advantage. Users are in control and user data security is a big issues these days and users manage their own payload and they send that data only to the people they choose when they choose. For the it’s folks it is containerized As some of you might know in Q4 Q4 we did community beta and with that we launched the final version of the bridge protocol key server contract under the NEO main net. We launched our production service and APIs and our bridge protocol on chrome exclusively and we had over one hundred community members go through the process and take their real world identity. For all of those out here who participated thank you, we heard your feedback. We have heard your feedback and now we are announcing in March 2019 we are doing the bridge protocol open launch. We are going to be doing version one. We have done extensive upgrades, based on your feedback we took the ex extension experience and revised it and now support chrome, Firefox and opera. We will release documentation and integrate into your DAppss and websites. We are going to be open sourcing the critical components of the bridge protocol, the SDK, extension client, integration modules so the community can get in here and help us extend the protocol In addition to that launch, we are talking about verification providers and types of claims on the network, our major initiative 2019 is announcing project Aver that is using intelligent identity processing. We are going to do digital and document verification for all government identities worldwide with advanced detection. Real time image analysis and pull information like age, gender, native language detection to get a good picture of who is sitting behind the computer and get that into the digital world and really identify them >> Stephen Hyduchak: You look at all these stokeen econom economies and we want to bring stray transportation additional businesses and players in here and we pulled back that layer and we were trying to offer this service and garner adoption

The businesses are looking for this service and this allows us to say hey we offer the service for half the cost. Trust me we have talked over ten providers in this space. This will also compliment the bridge protocol network. Besides basic due diligence, we have Geo location tracking through browsers and some of the best new technology that you can get when it comes to facial recognition and identity verification, so it’s pretty tool. Not only will this help STOs and exchanges but Medicare, finance, as you can see it’s a broad spectrum. In terms of adoption, the sky is the limit as far as we can sell it. Pretty excited about that It is going to reduce time. The bridge extension, I hope some of you guys have checked out out, if not, please do. It’s a very easy process. This will help speed that up as well I think that’s it. We really appreciated being here hope you enjoyed the video and our talk + >> Next up, I would like to bring Alan Fong he is the co- founder of city of Zion and moonlight (applause) >> Alan Fong: Hey guys thanks for being here for my talk about moonlight. There is a lot of cover so I might be going a bit quick I am the Co-founder of moonlight I have been part of the city of Zion. What is my business case? Now last year in order illustrate your business case I made a fun example you might recognize. I have been reading the YouTube chat, so I will give you a hey, hey, hey, just for fun. Anybody recognize this photo (fire alarm) Fes photo Frye fest cal. It was a 2016 luxury festival that promised everything, gourmet meals and you got to hang with celebrityies, but we all know how that turned out. Don’t see any celebrityies there. It was run by Billy McFar land and J a rule. This guy was such a scammer they put it next to his name on Wikipedia. He caused a lot of pain to some people. If you don’t know who this guy is, ask someone next to you. How did he manage to get so many people to guy into their scheme Turns out it was easy they promoted using social media influenceers, and they believed them by virtue of being famous None of these people had any qualifications unless Snapchat costs. Peopl People’s trust was bought and paid through these Chesapeake Bay celebrity influenceers. I got to say it’s not to be really embarrassing getting scammed because you didn’t watch the ” notebook To north Cree yeahs North Korea ‘s professional basketball player (laughter) It isn’t just celebrityies that people assign arbitrary qualification to. A huge number of people do it all over the

world. It’s just so easy for people to do If you know exaggeration, it’s a big word and it makes it seem harmless, I was just exaggerating, how many times have you heard that in your life? All the time. Sometimes they use a small word they say it’s inflation. But at the core these are lies. Even if place you go first for information, the places you trust still have no guarantee of the truth. A lot of people will take advantage of this for personal gain we call this fraud despite what Ja Rule calls this. These figure figures are just foreth they are for ether Ethereum alone. The Super Bowl champions are worth just $3.8 million, which is a lot but compared to the amount you are losing in fraud, you could buy the patriots over and over every single year, so it’s accurate to say we have an issue on our hand and our graphic designer did put other 1100 of those individually up there so, round of applause for that guy (applause) There you go. Good job, James. How do we take a step towards eliminating our reliance on true faith into something we believe in which isn’t just words. We call these ka per any cus Copernic Copernicus. Let’s start with this. With moonlight we allow anonymity and optional KYC s so you know if you are dealing with a specific person an you can log in with your favorite platforms and our headline feature is called creation of trus trustless digital resumes The trustless resume is why you can be anonymous. Trusting or faith is not the same as trus trusting what you are getting The work you do is published to a blockchain. Program For example, if you are a JavaScript God instead of just saying it, it’s possible to show people real proof of how quickly you have done your work and what skills you have shown and over time you will build up this resume. Right now people try to gauge competency by doing interviews and are terrible if you want to get a candidate of a person’s capability. Young to Yale study, interviews allowed participant s to make worse prediction Our second part is Kepler and it’s about recruiting people with trustless resumes resumes You can pay them in whatever way you want including crypto. I don’t know if you are aware of the gravity of this, but there is really nothing like this yet on the market and it will one hundred percent be a game changer. If you want to create a start up, getting the right people together is half the battle, so we are providing amazing capability that really hasn’t been seen before. People bid on task. You bid with how long you think it will take since the price is already set for the job issuer. People are incentiveized to create complete jobs quickly. If you keep promises work done faster than you do i it, people will be able

to see that and our system can adjust for thatment you can accurate a more accurate time estimate. To make it simple, the platform lets you know how well the result will probably do and how long it will take you. We support task dependencies. If you want to build a car, you have to assemble wheels before you assemble the car and these are taken care of by different people with different assets Before giving someone a task you can experience with what-if scenarios by swapping different candidates in an out. You can project the impact through a project cease completion window, so super convenient if you don’t know exactly who you need for the job. Our third part is call ed Galileo, and it’s all about project management. So project management might be some way the most important part of getting jobs done. We will off a full suite of PM tools and off the ability to clap collaborate with other teams and take samples from external testimonies testimony exsystem external systems It takes VB mapp of a whole lot of things for max activity That is not the only type of system that it’s limited to. We are partnered with VDT right now to help provide that. The last important thing I would like to reinforce is moonlight scales Every platform out there, fiber, freelanceer, Uber, Lyft, a person will drive you from here to there. Always one task a at time. It’s hard enough already to trust one random person with multiple people you don’t know. Even one bad egg can spoil a God thing good thing. You can hire, one, ten, or twenty people at the same time while knowing how they will interact and their timeline and knowing they are skilled No other project on the earth that can do this right now. So we have another initiative that we call constellation, which is not part of the moonlight platform per se, but will benefit the ecosystem it will be in. It is a decentral >> Dr. Junda Liu: Ed identity decentralized — we think it would be really important to get people to adopt these products, so think of it as invasive consortium for blockchain intelligent device. We are not the only member. You may have seen some of our members present ing today. You can find this graphic that summarizes everything on your website. So where are we now? Well, we are pretty far along with our first iteration Galileo With the platform you will log in with a simple beautiful home screen with a number of options and you can see those below. Simple contract creation You can start off by entering your previous work experience like with any other web so it This kind of self input information isn’t validated by our system. It’s not literally the work you have done, and confirmed. This is a way for people to get started and provide information before they do the trus trustless resume. That is always going to be our base and we can always go higher than that. You can define what

skills you want to advertise as having You will have easy way to view and manage your data and profile s. You can create more than one provile. It’s really cool Say you are great at dog training training and a great dog trainer and bulldozer operator. If you saw this dog train training, bulldozer operating photographer, you would see this guy doesn’t know what he is doing or a joke account and you might end up looking for someone with only one type of expertise. You know what I mean? It’s the way people’s minds work. You can split these up and reduce the bias and reduce that down to what each person is proven to they can provide for each skill set. No other platform provides this Another view of what you can do and this focuses on your education. It’s not validated In the future there may be a way to do that. Of course you can edit your information anytime you wants the really detailed so be prepared to spend as much time as you want. You can get really specific about everything you have done We give you ability to maintain your data and your account and you can see exactly what is available about you and we make it easy to deactivate your account if you don’t want it anymore, unlike some companies that like to bury that ability under 20 menus you have to go through. Security is also super port to us important to us. Especially if you hold any cryptotoe crypto crypto. You can see your activity from the dashboard, unlike some other companies like to bury this information. There is no reason to bury that by the way, so I have no reason why they do that. I think it is a nice looking platform don’t you think? Round of applause to our designers by the way. Thank you (applause) Our designers will thank you That is all I will show you guys today. We have a lot of amazing stuff cooking, so why don’t you keep your eye out our tine white paper or you can go to our website. Thanks i Thank Thank s for being here Next up is coil coil to talk about Blacat (applause) >> Sean Chen: Good evening ladies and gentlemen, sorry that this is my second English speech , so bekind to me okay. Thank you. Here is the thing. How many players, gameers in this room? Can you raise your hand? Okay, thank you. Let’s dive into the gaming industry I want to introduce our team, gaming industry almost over 15 years and we make successful games in China, maybe 60 million. You must think I’m rich, but most of it goes to the

publisher and the channels, so there is a few left to us, so I am still poor What is Blacat Blacat? At the end of 2017 we engageed the blockchain. Can we do games on blockchain and most of the revenue goes to the developer, right? Then we had this game called cryptokitty. If there is a centralized gaming platform that don’t count any revenue then they will go bankrupt, but we can do this in blockchain way because ec have the developers put it there in game assets like tokens, coins, and inventories and make their own chain and become digital assets So we decided to build Blacat I will give you some details after. This is the overview Basically we have the developers building the game on the blockchain, and then many of the issues that blockchain like slow and hard to use and expensive, many things of that we have established with NEO. I will give you more details after. We have the Blacat. We don’t have the revenue and worry transparency of the data to the users This is the game platform and we also have a market where players can trade with each other, right, then it comes to the developers and they get all of the revenue and to players they are holding their assets in their own hand that no one can take from them and they can make benefit from trading them. In our opinion this is good to the develops and MRIers MRI players You don’t want want to play games that most of the revenue comes to publisher and channel and it creates little value of the industry which the developers carry most of the value and they get less so, maybe when the revenue goes to the developers they can make quality and better games because they are well funded Fistfirst off, we embed the wallet. It can be embedded in the game, in the app. You so once you have to game you have your wallet, right, and then — sorry you can purchase coins inside the wallet. You can use bitcoin or NEO 3.0 or fat money. We also have the SDK interface and thicketsly embed the wallet in the game We have an SDK tool set Here is the other two. One is the game platform. As I mentioned that our game platform is different from this because — all the game data. Each kind of game data like the user

activities, the transactions and access and active users you can find the data in this platform and we are offering progress on the platform. You can come out with idea and set up a website or page on our platform if your idea is good and we are supporting you then you can raise fund like Kickstarter or doing some presale, but you need to do this and you need there for more transparency The game market they can trade their game assets I can sell the stuff I guy and get the money back and play another game, so we can make the excess flow and make the currency. In the traditional game in the global market there is $150 billion per year which is huge and if we can cut some revenue from the market and make it gross every year there would be many, many digital assets in in the second tier market. It’s good for the players because maybe they can make benefit from it Eventually they go boom like fortnight fort nite. This is what we do to benefit the player s and support the developers By this I think players will get more willing to play with us because they can keep their assets and nobody can take them by shutting down the server because we are blockchain games and the developers get most of the revenue, so its good for both of the important part of the gaming industry and why we can’t give up this revenue important thing is volume. We can cut out transaction fee, so we can complete with centralized platform. Maybe you know there is a game platform launched now that reduced part of revenue to 20 to 15 percent They have fortnite and many players. As I mentioned we are working on Zorochain. Why we do this? Right. , because for now the NEO chain or other chains maybe they can support the game level from transaction transaction speed is allow. The experience yens of the users is not as good as the centralized game, so I think we maybe need a response real quick I send to the Zoro chain and get my result immediately. The reaction comes in less than 1 second Maybe later in March we will have a test night online online We have multichain structure That means for each app , one chain for one D app So it’s one chain, one app structure. Also we have the guest fee payment from the developer. They can choose The developer can decide if this

— who is going to spend the guest fee for this master call, the user or developer because users can understand why I have taken bay my steel back — also we have the virtual machine. Basically doing this like building in the second lay er into the virtual machine that our own computing and also off-chain computing Off-chain computing is that we approve the cast of the operation but we don’t worry about that. This is called off- off-chain computing. This is the milestone of Zoro chain Q We also changed we are coping improving the response speed in like 200 or 300 mini seconds This is what we are planning, so I would like to introduce the tokens of Blacat. There are t hree kind of Cokeens. tokeens Yes, we are doing the security token offering now and preparing the paperworks in DNS. That came out of BCD which is means Blacat share is a security token The BCP and BCT is the utility platform The BCT is more like the stable coin. One cent, one BCT. Why should we have the BC T, because in traditional game developers don’t know blockchain and they don’t want it it. I receive the bitcoin from the player another have a 50 disdoesn’t count I lose my money. BCP is utility token that you can purchase by the bitcoin, so this is kind of yowl cryptoin our platform Anyone who has access can decide which token I want to charge Here is the picture for the utility token flow The player can purchase the token or game coin can or any other digital asset, but the way that they use ripe currency an use the fate fat coin and tender Once the player gets the BCO and BCT, — when they gave their token to the developer the developer can

redeem the fat money or currency from us. It is a circle like this. We both can serve the praadditional traditional game developer Also we encourage the developers that build blockchain style game s which have the logical on- on-chain, so these are two type of developers that we can serve So how to build and public a game publish a game in Blacat. We are offering our SDK. The dollar happy is on the dollar chain is on GitHub You test it. We supply many templates of the smart contracts like the NEP file and the action like an FT, a nonfundable spoken When you finish the test you can bring it online You just have to set up your game community on the platform and you can start gathering user s. We also have the cham the channel, we have the developers to publish the game — after that you take your game to the audience to the users If you want to know more, there is information on our website Blacat We are building a million NFT partnership for sale and once you buy, you bet a pro promotion code and through promotion code you can se everything from our platform platform. There is millions of dollars of reward during the million certificate sharing If you want to know more about this, you can go to our booth and ask for more information Here is our contact info. If you want to contact us, you can through this Last I want to mention that we have agile — also offering free certificate. If you want to get them you can also go the our booth. Thank you. This is Blacat (applause) >> Thank thanks Sean. We now have a panel. As always they have to bring their chairs up so we will give them a moment to come up Give them a round of (applause) (applause) >> Cole Peterson: I am here at dev. con representing

news BTC. We will talk about two relevant topics in game industry and the blockchain industry. Every day you are hearing about twitch streamers and YouTubeers making millions a month streaming games. It’s just becoming a really huge industry and then offing the blah chain industry i the blockchain is growing by leaps and bounds every day. We have great panelists here in the industry. Let’s start right here if you can introduce user and talk briefly about your project >> Rudy Rong hi everyone. Hi name is rudie, and I from magic cube. We found there is ways of gaming distribution and this made us invent the whole new ecosystem magic cube. We help them gain more users an increase their retentions >> Sean Chen: I am Sean Chen again >> Rayman Yang: We have welcomes over 50,000 users so far far. It is a sandbox game and users can create everything in the game, the buildings and the underlying mechanisms like the economics, the voting system s and it is quite like primitive version of a movie. It’s a read did ready player one, and virtual world with real economic s. Also I would like to clarify something because people are ask ing so many times what is the relationship between NEO and NEO world. NEO world is independent project from NEO. If you are asking the relationship about half a year ago I would like to answer there is no relationship between us and we started the collaboration since the end of last year and we have built a special — called the NEO lens which is a special one that use uses NEO as the main currency as the other economics activities NEO lend and NEO world. That is the response >> We did have one another panel ist, Parimal Deshpande who was unable to attend I want to start with you rudeie from magic cube. You already have a pretty large user base, but you’reous to hear your thoughts about what blockchain game platforms post to users and what they pose to developers >> We have started doing game publishing and we have published 23 games already and we onlily focused on social casino games, black jack, Texas hold em, and this year we are bringing out different games Everyone can search the games that we are bringing out, it is supposed to have 100,000 users on you play Check it out. What we really think it changed and what we are really trying to solve before magic cube we realized in the model there were a lot of users and not that many games, so we the conversion rates are allow in Google and Facebook and all the channels, so apps are not exactly working there are too

many games out there and not too many useers, so retaining the users is a key. When a new game first came out that communities is not out yet and the contents are not out yet. Ask a pl player wild you want to choose a game instead of going to a more mature game in the same genre We introduced initial game offering, so basically the early adopters of game like magic soap if you play it early in the firstmont first month you can gain more tokens with the same amount of time investing it and same amount of game regenerate It is call called game mining Later on when there are new contents that come out, the consumption of these token token s are going to increase so the demand in total are going to increase, so it’s more of a demand driven growing curve compared to the other which I see us and we are selling to the market selling to the mart. We on the other hand are trying to solve problems and create utility tokens that have demands right here and right now now >> Shawn I want to ask you the next question. One concern is what if a group of developers stops developing the game that people have invested and bought the assets within the game and it stops developing >> Sean Chen: You know open source project like Linux people come in and out For the block blockchain go they must go open sourceed and build the project, but they are not like the only one If the core team want to quit, and there must another guy to join buzz there is many investor s and many things, value in the community, so they will Capitol and someone will will continue and someone will come in an maintain this game It’s not a technical problem, it’s how do you — your games within blockchain sort. Okay, thank you >> Rayman, I would like to hear more about the token economy with NEO land and your thoughts on token economyies within these decentralized gameed >> Rayman Yang: NEO land is a part of NEO world and ecosystem is similar to NEO world, so I will start with NEO world token design. We have a three layer token design and the first one is currency, and it is Nash. In NEO land it’s NEO and we use NEO as the main currency The second layer is continental RO, so in each continent we have this specific RO. to represent the user rights. The value of the RO will depend on the economy of the continent very much. If the economy is good the prize will go high and if it is bad, it will be going down, so it’s something like it’s a company stock in the real world, so last is nest which is global rights and a physical tool in the game. When the economy is going too hot, it will provide a buffer, and it will provide a boost if the Citix is going allow. These three layers will work together to help to stabilize total economy of the whole world

>> Would like tommy on to group questions on anyone is able to answer these. If you are a gameer and moving on to a decentralized platform, what is the experience like. How does a decentralization blockchain game affect the user experience. Is it better or worse? >> We at magic cube try to make the user experience as seamless as possible, so — embedded directly inside the games games. The gameers can always open the page and trade their agile tokens inside the game. We try to make the blockchain game a seamless experience for all users I can tell you every new step introduced to the user is one or two dollars more to acquire a new user and this money adds up if you are Troy trying to get more users. You are talking about millions more if you are trying to educate the users. We don’t try to educate them, we try to give them the best experience possible >> Sean Chen: Two perspectives. We try to keep the blockchain game that has the same experience as the centralized game. The MRIer don’t even mind where you are a blockchain game or not. They want to play good games, so from technology part we blockchain must be as fast as centralized game. This is a tech any technical part, and from economic part I think they will be different. There is so much people in the same game and the data is so much excess and even trading so from this point the blockchain may have the economic change like the limited issue of access to have the trading and have the value go up not inplain inflate, inflation, right >> The next thing I want to talk about are what are the next steps from a developer’s perspective that need to be taken to improve the user experience on to blockchain based games >> Sean Chen: I think it depends on the blockchain, like NEO, I wish they would go further and have high TPS and we can build the central >> Dr. Junda Liu: Ed part of decentralized part in there too to achieve the centized game experience >> Do you have any other thoughts on that? Rudy Rong based on our interactions with the gaming developers, I think that is something they would be concerned about our first legal part, so I think that’s really important for us to have a legal team gather all the info and let the game developers know it’s safe to work with us because a lot of games we are working that we publish are from public companies in China like Tansin and perfect world. That is how we are trying to make them more willing to incorporate the blockchain. For the small developers, it’s better for them to work with second lay layer protocol or Blacat or second lay er because it’s easier for them to incorporate and don’t have to go through a hard time of understanding the publishing and all these TPS issues >> The next I want to talk about is what’s commonly known in the gaming industry as the publisher ‘s monopoly where the publishers will take a significant amount of money away from the developer s, blockchain games kind of remove that and allow for freedom and money for the developers. Do you guy want to

talk about that and how blockchain helps save money Rudy Rong e we were taking 80% of the revenue overall and we realized that is not works and why we tried to develop a platform that gives it back The traditional way of publish ing doesn’t work anymore. When is the last time you clicked on your apps on your phone, right? People don’t do it no more, and that is a problem and that is why retaining users and giving back value to the users is key I belief this blockchain game is going to replace as the third biggest gaming revenue. It goes through two stages the 1.0 was you pay to play and you pay for the hours in war of war craft In China, a game revolutionize revolutionized it and put out the — and everyone transferred to 2.0 at the same time, but the 3.0 is when we are really giving it back to the users. You can observe that in the industry in other games >> Sean Chen: I agree with rudeie, and I want to add this. No matter your centralized blockchain, you the public published act you also need Very different from the traditional of the publisher because the information is — you can easily achieve information. Let’s say Fortnite, it’s a boom. If we have some incentive from the game, right, if you found the core of the game earlier than the others and you purchase assets, you get benefit, so this is a different published way I think. This is a whole new thing and we call it community Maybe we invented this word, a community operation. If you mind this game is good, you can tell anybody and they get it, you can get some benefit from it, so I think this the way that we have people that the users publish the game themselves and then they get the benefit, but not some company >> So we only have about a minute left. One last thing S Sean is about blockchain increasing the trance parentcy >> Sean Chen: Everything will go to blockchain this is our purpose The speed is fast enough I think for now so because it’s on chain , we can recognize how many act ive users, how many transactions , how many total users and every detail. You can see which — say the best you can check it on-chain There is more issues about the privacy so maybe something that we need to figure out for that >> I want to thank our panelistst this is a great discussion and there is no discussion that tease two industries are improving by leap s and bounds every day. Thank very much. I hope everyone has a good event (applause) >> Next up Mark Jeffrey, he is the Co-founder and CEO of guardian circle (applause)

>> Mark Jeffrey: So guardian circle is a community emergency response network. It lets friends, family and neighbors help one another in a crisis situation. The big problem that we are solving 6 billion people on earth have no 911. There is no magic numb they can call when bad things happen. If you lif in the quite we do have 911, but when you call from a mobile device, they don’t know where you are which is amazing. Uber can find you easier in 911. Also it doesn’t scale in mass emergencyies. The centers are overwhelmed overwhelmed and they can’t handle the cals Recently in Florida they announced they would not answer the phone. 911 does not find those nearest the emergency because it has no concept of these people. The way the world should work is no matter where you are on earth whenever you are in trouble all you should have to do is presa button and this send the alert up to the cloud and it looks down and sees what resources are near you and pushes this help to you as quick ly as possible You should say we are in the flash mob helper business. It’s edge delivery, we are crediting this new CDN of help. When you are in trouble open the app, broadcast alert by hitting the alert button or you can use one of devices that are associated with your accounts via the guardian circle amount of FIA API. . The alert goes out out It starts with your guardians, those who you have pre preconnected to in the network If you opt into this, it can be nearby citizens, so these are strangers who happen to be nearby who are also running the guardian circle app. Later on we will add in operate response and official response. When the responders get the alert they are brought into your alert room which looks like this. In under 130 seconds everybody knows where everybody else is and everybody can talk to everybody Now they can come up with a plan to help you. Whether they knew each other beforehand and hands are they don’t. Now everyone that responded is on your page and you respond. When you are happy with it, you click to tip Notice this is a one click to tip. We have equated our token guard to safety. It is tieed to tangible real world value. Our users are ripe first world ripe cryptofirst time users. . When we decided we needed to provide this experience to our users we decided it was only possible to do it with NEO because they give the primitives we need to do it The way it works is like this, when you download guardian circle we generate new wallet address and drop you some guard to start you off and we bake guard in. In NEO new wallet generation is free. We did look at iOS, but if we got a million new newers it would cost between a million and two million dollars some benefit that accrues back to NEO. We have a very compelling reason, p mutual

safety for your users to grant access to their contacts and send each other invites. We make this easy through our in in-app contract manage. Each sign-up produce as new wallet and we think the result will be a lot of NEO end user consumer growth. If that is not enough anytime you refer a friend, they earn guard. For people who are unbanked and have no 911 They are earning safe safety by helping us be develop our network. Something else that falls out of all of this. In our universe you can send guard to someone by only their name and don’t need to know their crypto address. This is made possible by in-app wallet and sophisticated in-app manager It was hard to get right and we are there now thank God Privacy is big in our universe You have control over who can get your alert alerts and who can send you alerts, and your location is always, always, always private until you enter an alert room because it’s shared. When you leave an alert room your location is private again. It will scale in an mass emergency. Things like hurricanes, wildfires, where there is a lot of people in trouble at once. It’s like putting calls on hold and jumping in and out of different alertm Roo alert rooms and we provide alert transcripts. This is a chat log with information and time stamped. Useful if you p want to review alerts like you had your phone off and Tim has an emergency and I want to look at what happened with Tim. The transcripts will be immutable and corruption proof. No one can alter the evidence and everyone can be sure this is a true an accurate representation of what happened. A couple week s ago “Newsweek” named us as nominee for blockchain awards We are in a domry called trust call documentary called trust machine. This is in theaters now and will go on strea streaming in about a month. We are in a new television series called the rise of blockchain and executively prosecute executive produced by Leonardo DiCaprio Tarting in Starting in March of 2019 we will be exposed to millions of consumers so we think this will be good for our app Any hardware manufacture er can can connect any divide device to our grid Wander management, where if you are a little older and you get confused and you break a geo fence that can send off the alert. The way it is you stake guard for API access as devoice alert manufacturer. You give us wallet address and we give you back is These are devices that have been added. We have partners with the women’s safety X prize

22 of them went to the final round and we went to Mumbai, India. That is my watch going off like crazy from all the watching generating alerts one of the contest tents move into production. Employs this into assisted living homes in South Carolina. We connect connected Amazon Alexa to our own working grid and this is working today How does official response participate. Basically this is anyone who has a geography within which they are responsible for the safety of people, so the obvious example is a city or a municipality, think smart city initiatives and that sort of thing, hotels, resorts, people parks like Disney land, corporate campuses like Facebook or Google. These organizations stake guard to access all alerts occurring within their geo fence. The bigger area is you want to patrol the more stake forward it guard it costs. We give you access to guardian circle dispatch. This is the God moment that Chris, my partner, and I have access to and we will con train it to the geography your you defined. This is a mock-up , screenshot. Now you have been introduced to the pieces and parts. This is what it looks like from the 5,000-foot view and how the pieces and parts fit together. Guardian circle 3.0 release is coming at the end of February for iOS and Android That’s it thank you for listening (applause) I would like to bring to stage >> Jonathan Meiri: She is the CEO and founder of barrel protocol >> Jonathan Meiri: Hi, everybody. I am standing between you and the last break I am here today as a what is that called, council member of barrel protocol. Barrel protocol is all about compliance and pricy and how privacy. I want to provide you fee feedback on how to interact with NEO just from my own personal story and nobody at NEO asked me to do this, but this helped me about a year ago when I started exploring different blockchains and platforms to work with. My first interaction with NEO was in San Francis so in the first dev. con. I came and signed up and the nice lady asked me for my phone number and I said+972. A man standing next to me said, hey are you from Israel, and I said yes, and here I am today and theing standing on stage and having received funding but it didn’t happen overnight. First after all talk to people and ask them about their platform, beyou’re curious Try to join a hackathon Try to set up your own hackathon Fly around the world with the team and get to know them and the feedback you get is invaluable If you secure funding from a specific team you know you made the right decision on securing a platform. That is what I went through and I would recommend to you to hit a few of those same spots Let’s talk about data You open up the news and it’s all about data. I put on the

screen a few quotes. How many read anything from Nuvai Harari. I would recommend read ing his books. Where is my data , who is using it? What are they doing with it and can I trust them? There is three pool s of consumer data, Facebook world, Google world, and e-mail E-mail is are also partly owned by the GEMO platform So I mentioned this huge amount o amount of anxiety around who is using it on my behalf and why am I not making anything about this and Facebook, giving them information about ourselves and sharing pictures and intimate discussions. Facebook is one of the biggest losing losing 40% of the trust it earned. You learned about the conversation on record that zuck talks about your data you have to right to be con sensed. concerned There is a whole bunch of breaches across almost my brand name if it’s in the travel industry, if it’s software, eBay is here and really huge distrust around data A been and what restaurants I went to Why are people buying and selling your data? Because there is a ton of value in our data. Supposeing Google and the dark weapon dark web, you can pay and get people’s passwords for this services. You can look it up. Google is doing something similar, selling you to an advertiser and getting a lot of money for it, so if you are looking for a mortgage, these are pretty recent numbers Things that go online to do a nice search, but someone is selling that lead and making a lot of money to the tune of $30 million of revenue that Google made last year. What is barrel protocol about? A clear mission to help people people that they are in control of your data You have heard a bunch of people present this. I like to focus on not the privacy component but the monetization. When people talk about this, they think about an app that’s making money off from me. What we are going to do here is show you how you starting today can start making money off this data. How, and if there are developers in the crowd, it’s really a set of API calls for developers that will pay their users for their anonymous data. You say if it’s anonymous, how can I get paid for it? There is a huge, huge market in alternative data. I can talk about the whole arc on the slide, but there is the four horseman of alternative data There is click stream, there is geo location, a anonymize a anonymizeed and there is receipts. These might be Uber or any app you sign up for. If I see all your personal receipts I would know something about you and multiply that by so 10

million and now we have insights on the companies. We care about what that means in a large panel Those insights are being sought after to the point of seven- seven-digit deals with hedge funds and those very much driven by discounts. I know the space well because we recently close closed the deal with a company that lif lives off data They don’t want your personal data but the I will give you a sense of what we believe is the data Bill of Rights. No PII should ever be shareed with everyone. Second ly, what is it worth, every time I want to know it. Who is buy ing it? Maybe I don’t want to sell my data to a certain vendor , and what are they doing with it. Of course on the developer side this is an API and they will be the customers of this In line with the California privacy law, and integration with any AW is.S service. They can choose to pay their user s , and to participate in this alternative data market. The California governor ahead of his time saying we should force Facebook and Google to give a dividend to their customers With that in mind, I would like to launch today a spender track er app. It will start to pay you for every single receipt that you have. We don’t cover tall receipts in the world. We will tart with the popular item s. If you are going to be Pate one of the first 50 oh users five cents for every anonymous receipt you share in per pa Tutti perpetuity. A dollar or three or four or twenty or third. I have about 10 seconds before I finished. Pull your phone and go to spender tracker and sign up, it’s a one click and from this point on forever as long as the company exists and doesn’t go broke, you will be paid in your currency of choice a nickel for every anonymizeed e-mail you care to share. This machine to man type receipts. Nothing personal. We don’t read personal e-mails. This is what the website looks like. You are going to click it. Spender We loaded this up over the weekend Try to use whichever account has the most recents. This is what the signup looks like. Read what you are signing up here Read only access to make sure you know what you did. I am out of time, thank very much much, please sign up >> With that we are on a break. We will be back at 3:30 right? We will be back in 20 minutes As I mentioned before there is one last set of T-shirts that has to go. It’s either that or I bring them home and they won’t fit me. See you back here in a little bit name back to registration, and you will be receiving material

thes after the conference. I would like to bring up Joe, the

co- founder of Jarvis plus (applause)

>> Joe Zhou: Hey, everyone. In the past year we

have been working on many community projects with partners

including the blockchain and nonblockchain projects and we see very interesting change is happening across the industry, so this is the purpose on which this session, and I am going to introduce what we are seeing and it deserves noticing. We attend ed dev. con last year in San Francisco, and this is our partner and AI scientist. Since dove dev. con we have been talking a lot about how AI and off- off-chain with help the project to understand the community and the members and their voice better. After dev. con we built demos into the project, and we are working with many token farm s in China We are helping some of their projects to adopt our technology to work on their community to manage the community economy better. China also came to us an wanted to understand whether our technology can help their communities. They are not blockchain projects but we are highly interested in the community and when we talk close with these partners, we look into different scenarios and the way the corporate goes we see a very interesting change happening in this industries, and this is what I’m going to introduce. We call this any economy. First of all I will talk about bounty programs. If you are a blockchain guy, you should be very familiar with the bounty tram program, it gives out value to your users, and make them work for you and the users will bring you new users and they will bring more new new users I don’t want to talk about names but I know quite a few of them and this is PDD This is

What is special about PDD is it’s business is happening on the mobile internet, more specifically happening on the social network or more specifically happening in the mobile communities This is a screenshot from the mobile community that says that there are more than 800,000 people use this to cut the price Come over here and help me to cut price, so that I can even get something for free is the message from PDD. Let’s remind you of the bounty program to give value to the users to have them bring more users This is a newly Nasdaq listed company. The screenshot is from LAIX user. The Chinese message says I have been in for 49 days. Today ‘s topic is our it should work — I will say the last is more aggressive. The model is very interesting. When the lakes LI AX got new users, it didn’t ask to download first, instead it asked to join the community first, and they even use the community as a classroom to urge its user to post its study progress in the groups to let students choose their friends and they are teachers or volunteers in the last group It helps to answer questions and make comments to the student students, something like that, so I will say this pod El is much more likely to — the users go to the community and actually the things, most of the things are happening in the community instead of (indiscernible), so I think it’s very, very interesting. Then we also say this. This is from many Chinese games. The message it says is like share me to your friends and you will get the gold, or else you will get ten I do Monday. The Tendai ten ten diamonds. Based on our observation, we see that these cases va similar pattern. Traffic means new user , for these projects when there are new users, the first thing in the project we will do is identify users who share the, who will like the its value and who will like the model, and who will accept. We call consensus for blockchain to build consensus it’s the white paper It’s the AMA and the interviews and the Q & A or Mead meetups or even the dev. con we think is to build consensus. For the PDD when the users help their friends to cut a price, the user s will look at at the PDD goods, and the goods have the same standard, it has a very good price, but not that good quality It even has some fake blands on brands on PDD. If you accept a model of good price but less good quality, then you are like

ly to use a PDD and be a part of it. The last consensus is whether you would like to improve your English in the Chinese users or whether you will feel anxiety or curiosity when you see your friend is improving his English English, if yes, you will accept the consensus of LAIX and likely by its useers. If you play a game for 30 second and do not quit and you still play it, that mean s you accept it’s part and it’s game play. You accept the consensus you want to be the game player, so after the consensus disspout, the dispute. We will give out a value for users to do things for them We can see that it will keep circling around those three step s The product grows bigger and bigger bigger and we see successful case like PDD and use the circle to be listed, 30 billion or more something like that Maybe the token economic is part of something bigger called the token economy. It is something special because it gives us token instead of paper money, so in theory money the committee member that accepts token bill lock at look as it a it as a long-term value We the it is a little bit special but it’s not alone. We can see that there are similar things happening in other industries in this blockchain industry, and we believe it will be a global change to ledge a committee and economics based on that. Why do we think that? There are two reasons. The first of all because the growth of the mobile internet. This chart is from the research gate. It’s the growth of smartphone penetration among population. We can see that the smartphone is still growing among population. It helps a lot of mobile users tart to start to use the internet. They were previously not internet users Even narrow sentiment can have its voice spread and can find users to accept it’s sense it’s consensus. That matter how small at at at the beginning it can have a tipping point. That means if we do something around the community community this things becomes possible and there are big brand in why that working on that. Also, we believe it is because of the mobile payment. Why we see these cases happening in other industry. Why do we see these things in China right now? Mobile payment is very advanceed in China right now. In China it’s possible that you do business only on mobile. You accept payment only in the community only on the mobile device. This can grow into a very big business. Whereas in other parts of the world because of the privacy and efficient efficiency, the mobile payment is not adopted yet, but we say we believe these problems could be involved in maybe three or five years When it is solved, we think the community economic might be the trend. Young

people are growing up and the young people, from very young they are living in the communities and are living on mobile, so we think that the community economy will only be changeed in the future. This year what we are working on after we figure out what is happening and we believe this will be aCh’ie achieveed We integrate into different industries. I just want to let you know that there are many things that could be done in the community economy, for example, we are helping these big brand in China to do did tokennization to use token as incentive for communities because we believe that the token will make people look at the long-term value. If these guys don’t want the adopt the blockchain, that is fine we will make the model will work and function in the system. The other thing is that there are a lot of things to be automateed in the system like when you give rewards and incentive to bolster big influenceers or the small users Could be part of the economy, the community economy while we will eliminate the loopholes so that no one can expose the loophole to benefit himself, and like to view the consensus like when you choose a lot of things like customerification with help users to understand the idea and value of the project but in a much easier way, and like we will also do some opinion lead ing to help the user to look at the many aspects of the project instead of looking at something not very important A lot of things need to be done in this very new community Citix, and there are big chunk chunks, big opportunities there, so that is why we want to share what we offer you and urge you to look at at this. We have a channel called the Jarvis plug and plus We will keep updating our progress in the channel and if interested you can follow the channel and understand our recent progress. Thank you, guy s >> Thank you very much (applause) There are projects that will air drop their token to you, so please leave your information at the registration area Eric Wang Archon >> Eric Wang: Hi, everyone I my name is Eric Wang and I am a Co-founder of Archon NEO is a very powerful an influential blockchain and this allows users to develop decentralized applicationings. Storage is a critical component of adapt developers tax about We will begin be bereviewing the two more common options that people use when thinking about implementing storage in adapt tech stock The most obvious application is Amazon S3 and any other central centralized cloud storage platform. Amazon is extremely

powerful and it’s convenient and cheap and been integrated through so many other platforms There is one major issue Amazon suffers from is that others control your data and as a corollary am am my corollary am — results in millions and billions of data loss. Can we find a solution. The short answer is yes. The first solution that does decentralize storage and does it well, which I am sure many of you know about be IPFS. It makes it very, very easy to find files and it’s actually quite powerful and great for many, many files Many developers have implemented it. However upon reviewing IPF is. Further it’s clear that it’s not a perfect solution for decentralized file storage There is no strong incentive mechanism for users to store and deliver their data security as well as the inherent DHT, which is hash table structure renders it susceptible to attacks and these attacks allow any malicious attacker to manipulate the files that people will see with just a small amount of resources, so luckily people have figured that out and developed a temporary solution at least to address this problem. This involves using centralized IPFS nodes wrapped around Amazon S3 instances Because they are by themselves powerful and usey to use easy to use, they don’t suffer from lack of need for any token mechanism or any lack of solid decentralized structure, however , this is not a good long-term solution because once again those solutions will suffer from the fact that others will once again be able to control your own data. The third solution that I’m going to talk be the I believe has the potential to really be the long-term desen that centralized storage solution Companies such as us are using the blockchain in many innovative ways such as and this allows you to not only control your data, but gives benefits such as crypt to graphic and sensorship resistance They are also resistant to black swan events and collective down time. They have helped various small performance benefits over say ma’am Amazon S3. Different companies have useed the blockchain itself for a different technical reasons, such as to coordinate nodes, for smart contracts and these different companies have used the blockchain in different innovative ways However, on this slides I talk about the benefits that it has, but the grim reality is there is a ton of issues that these knees these need need need to overcome A haste ill Hastily done graph that I did a few day ace ago correctly only stored 300 byeses of data

300 Tera bytes of data. Why is there such a wide disparity? There are many issues for blockchain based storage system to overcome before it can be widely adopt adopted. There is really various issues with performance. There is a lack of features for many commercial case uses. The blockchains are not yet scalable and the token economics are not that well DEX fined yet and they are hard to implement and generally have pretty bad UX, etc. To I would say there is two frontiers that blockchain base file sources need to improve on. One is the technology itself and one is the platform for end users. With these ideas in mind that formed the basis of how we in our Archo n wanted to design a close based storage solution that users in my supported blockchain can use We have developed a set of in house erasure codes which alu aallow you code a file and you — these files and contribute it to a custom blank — we are the first storage network with a byzantine — even if a large percent of these storm providers in your storage providers — even if an attacker is very powerful, they are not beginning to be able to take down your file. We have tailored other custom features just as custom name that allows you to search and find your files with a very small over head and over features that creates native blockchain for file storage. If you are a NEO user we have smart contract integration where you can play for NEO tokens to upload any final in a centralized network and make that file decentralization file. And understand you upload it the downloader can download it without having any knowledge of blockchain Integrating with top chains like NEO allows us to — files can be exchanged between different blockchains and that allows to grow within DAppss. Say you wanted to decentralize this image of a dog. This is just a normal picture of a dog, and I want to host it in a decentralized manner it’s pretty straightforward. To upload this file, you put in some various parameters, such as how long you want to upload it for and as an uploader in Archon you pay for the upload and the end user to downloa download. In the H TML code you add one line of JavaScript code and add the URL that is obtain obtained from the upload and the end user will be able to view that file without installing anything, so the end useer experience will be like browsing a decentralized file as if it were from a centralized system. The big picture that we want to bring is that we want to make the decentralized internet just as powerful and reliability as the existing centralized internet with all the benefits that decentralized touts. To conclude my talk, I basically want to give a call to action, so for use users who want to

learn more about our platform we have our first beta March 1 and first public test net on March 31. Please go to www.a Thank you. I would like to bring to the stage Chris Qi he is the CEO of Alchemint >> Chris Qi: Good afternoon everybody and thanks for still being here with us. I am Chris from Alchemint. Today I want to share some opinions about what we think about stable coin To be honest there always exists misunderstanding from bitcoin believer about we already have U.S. dollars and why do we need a crypt currency like U.S dollars. In 1976 the famous economic Frederick Hav Havek aannounceed private money that could compete against government Since two fascinating advances in ripe graphfy grap ripe graphfy It made it possible that anyone should issue private money and what happened afterwards is that bitcoin believer believeed that crypt currency, they can be the equivalent currency and some thought it would replace money in the futures. Many commercial institutions try to offer bitcoin payment service and even got the permission of regulatory authority in some countries. At the same time, entrepreneurial boom of DApps come up , createed their own token and claim that those token are used for in the e ecology they will create later. In the current situation, this experiment doesn’t go well Bitcoin is big in Japan and recognized by government as legal tender. Over 20,000 merchants accept it for that is products and services. In this business, the payment service provide and pay an important rote role They cut down the fee to 1% to the merchant compared to 3% for the service. It eliminate s the volatility risk for merchants. When a customer makes a payment in bitcoin, it converts to Japanese Yen, and merchants receive yen instead of bitcoin, which is indispensable for their acceptance, but unfortunately these advantages haven’t made the bitcoin payment for mop pew popular in Japan We visited restaurants and talk ed to their staff for serving and vetted payment service to figure out the real operation condition and the result is frustrating. In fact, the volume of bit county bitcoin payment is almost negligible. Z

They receive one bitcoin payment per day and the other face the same problem they don’t find customers paying with bitcoin People are not willing to hold bitcoin and just expect to use it at checkout, especially while they have other options without risk How about the situation of DAppss. Let’s like at the statistical data of 1800 DApps coded from a thirds party website. We are disappointed to find out that over has less than 10 active users per day Only three has continuous goys goysing users use continuous growing users. Most never survivorred within the first month or continues The top ten DAppss are mainly distributed in games and gap gambling and they usually leave quickly after a bonus of fresh DApps exhaust. At the moment there is no indication of successful case that would bring investment of real value This lead to bubble burst in the last year which deserves our serious reflection about where did we go wrong. In Among all these problems, I think the — should list as number one and that means if we don’t solve the volatility risks there won’t be any change even if we solve all the rest problem. Let’s just try to imagine such a situation if the user app we are using now , say Uber or air B & B, would it be a killer app or a dead app? I would think it’s probably dead. If you are a driver, are you willing to receive bitcoin or if you are a customer are you willing to spend bitcoin can or just hold some and expect to use it and pay for it for the rent I won’t do that. Holding bitcoin is too risky for me. If there is another another Uber app that supports supports bitcoin, I would rather use that app. If your cush currency has unstable price people will not use it. We consider bit bitcoin as invest ment we will never use it as every day currency There is some fundamental principles of economics that can never be broken. One of those is that the stable purchasing power of currency is most significant quality of currency if modern commodities economy People realize that, so the

stable coin appeared in the blockchain world The most popular stable coin at present is USDT issued by teth er. Each is backed by one U.S dollar in tether’s bank account This is a way of createing stable coin called Fiat- Fiat-back stable coin. Despite the rumors surrounding U SDT, I have to point out that the major problem of USDT is its position to be a crypt to currency. In my opinion, it is more like offshore dollars using blockchain technology as it payment The only purpose of it for the moment is just to let the traditional money enter into the cryptomarket. I didn’t see it make any contribution to the growth and maturity of decentralized economy which deserves more attention in this blockchain revolution, so we are dedicated to make a kind of stable economy which is generated by inherent power of blockchain in a more decentralized way. Our stable coin which really belongs to the centralized community instead of capital predators, so we encourage all communities and crypto- crypto-collateralized stable coin SDUSD is a loan against NEO, so it’s totally different from USDT. U SDT is full reserve We can’t make sure that the dollar reserve is safe or not or issue without real dollars Sorry. Contrary, SDUSD is over collateralizeed. It is backed by more than one dollar worth of crypto locked into a smart contract The risk of these two types of stable coin is different. The risk is caused by individual fallibility which is an inherent quality of human and cannot be avoided. The risk of crypto- collateral crypto-collateralized stable coin is by — of code which can be avoided by script audit and verifyied by long-term operation operations. Anyone who has NEO assert aasset asset can leverage them at smart asset reserve This locking collateral inside the until it is covered by a an equivalent amount of SDUSD It is quote simple and accomplished on the blockchain

without authority to do so. It only takes you three steps to finish generating. Step one, you should send the traunch to Alchemint to create your own account with your new address. Step two, you should send another to NEO as collateral. Step 3, you receive the amount of SDUSD from your is. AR, and in return your SAR will return an equivalent amount of date locking you out of access to the collateral until the outstanding debt is paid If you count feel it’s convenient, Alchemint made a one click function that allows you to make all these steps in one operation. You just decide the amount of NEO that you want to send and the amount of disuse SDUSD. It is available on any NEO wallet On the first stage of application of SDUSD, we were listing on cryptocurrency exchanges and it will be more acceptable in the broad field with our continuous work in the following years When you want to retrieve your NEO, you must pay down your debt first and a service fee that accrues from the date over time Step one, you should send SDUSD to SAR paying down your debt or part of it. With the debt paying down you can freely retrieve your NEO back to your wallet by sending us transaction into Alchemint Stability mechanism is designed to achieve one goal, a token that is approaching the value of $1 USD. Each is always back ed by over collateralized NEO asset and there is always enough to cover the value and this is guaranteed by Smart Contract and independent actors will inten vise incentiveize When NEO prize changes the date, your SAR change changes. As it rises your SAR will be safer There is a bottom line of liquid diagnoses ratio set at 115% of Alchemint so far. Any S AR under liquidation ratio is considered too risky and can be liquidated by any SDUSD holders The holder can pay down your debt and take your cor ponding amount corresponding NEO at a discount ed price, so you will suffer a loss, thus you should always keep your SAR safe. To summarize, original actors are incentiveize to remove rest date

from the system by paying it off Owners who find the date too risky we can see that SDUSD is total decentralization. There is Notre additional bank and SDUSD with U.S. dollars and no Goth governments can shut it down It lives entirely on the newest blockchains. It cannot be controlled by a company or organizations There is a transparent rule of code. The most valuable part of the — I have to emfa size that the exploration of decentralized economy is the most valuable part. Our lives have been ruled by centralized operation for a long long time in enterprise organization, games, banks, securityies exchanges, media currency and everything else of scale or centralized operation operation It has been around and is so pervasive, it’s hard to imagine there is any way it can be organized. Blockchain technologies bring pos be the of ability of createing a brand new form of economy Distributed, encrypted, trust less, border borderless, anticensorship. All these features have never happened in the history of human civilizations which deserves our high expectation about whether it will make your life better or enhance our life Just like to the human body, there is a central intermediary by which everything can be organizeed in a centralized way and it cannot be sub city substituted the decentralized economy is still at it’s — one biggest problem is the shot of qualifyied crypt to asset as , the crypto cryptocurrency is too Naida CI All-in-One Solution generate to neat need of centralized economy, and another problem is isolation of cryptoasset in different public chains which mak makes the liquidity more serious, but tokenization of real asset there is irreversible trend and brings huge value to the blockchain as collateral The technology will be mature in the following two years I think and there are many good teams working op on it including us and fascinating progress like we remove the obstacle in front of us. At that time it will review its great advantages and become the central of

decentralized economic. T at when we talk about cryptocurrency or bitcoin, — laid the foundation for cryptocurrencies we see today, but I want to argue that haikais hey Haye k’s hypothetical currencies — in this book he makes a case that private banks should believe to issue tare their own currencyies createing a private market for the control of these currencyies A bank. Banks will strive to manage the supply more reasonably than governmentsed to. How to keep the stable of our money instead of how to create usage of that. That value is a precondition over all other qualities of wild widely adopted currency. That is the key Maybe the bitcoin in our last ten years was just a prelude It’s the first of decentralized stable coin may be the chapter one of this great blockchain revolution. That is my presentation. Thanks for your presentation >> Thank you very much We now have a panel >> Hello, everyone thank you for sticking around. I think we are beginning to be talking about STOs in this panel which I think is the last panel of the day actually. Before I dive in, I will let the panel introduce themselves >> Angela Tong: I am the CEO of Jinse finance. Jinse finance provides individual interviews and news flash and quick mart cap and we also hold worldwide media events and in this honor of this month I will we will host in Tokyo, so if anyone wants to go there you can contact with me and for coin time. That is the English version of Jinse finance, and also we are launching Japanese version and Korean version in April. Meaningish is not so good >> You are doing well so far >> Angela Tong: Thank you. I was staring at my thank you >> >> Waldemar Scherer: My name is >> Waldemar Scherer: I work with the ecosystem growth department and also working on work in regards to security tokens >> My name is Bryan at a company called republic. Thanks to NEO capital rehave been able

to exist. Nonaccredited tail and not accredited invest to be investors to participate >> Drey Ng: Hi I am Drey Ng, and I am the chief product officer of liquefy >> Sound like we have a broad range of people and sound like you might benefit from STO s, so I will apologize if I do play devil’s advocate at any point A lot of people are starting to say they will fix all the problems of ICOs, which 80% had issues involved with them and they haven’t launched products With them comes the regulatory side of things, which means there is more hurdles to jump through and invest investment opportunities would be taken a way from a lot of people that would be able to invest in I STO s. What are the characteristics of an S. The O that SS STOs that we need to pay attention to >> Waldemar Scherer: If we are creating real securities backed by assets it’s not completely new phenomenon. The ICO market aimed to gain access of who is a credited investor in order to participate in basically what is a crowd sale just using tokens I think security tokens are lock access at the same concept of accredited investors. We are not talking about everybody who passes basic — but credit credited investors but with securityies and through digital ization we have access to dig talart and div vend and by cutting out the middleman, we can ensure that small contracts that are executed in this contract are done in a cheaper, faster, and more transparent way. I think STO will revive the ICO market is misunderstanding the concept of what is a securit security token >> Thank you Bryan, what are the benefits of using blockchain when using STO token tokens >> Just to piggyback off from Tamar was saying. You are just doing an ICO and following security’s laws. What blockchain allows you to do is provide you a quicker path to liquidity and allows you to fractionize and allows more people to own things that are typically aliquid. Good examples are real estate, pieces of art, things not easily tread able, tread tradeable, but if you tokenize it it and provide them to anybody provided you follow the security ‘s laws and maybe in the future when there is more exchanges and liquidity on them, there will be enhanced path to secure based on unlimited amounts to access >> Interesting. I think it would be unargued to say that we have to satisfy a lot of different jurisdictions. One thing that I have spoken about with my Leeings is my colleagues is we look at securityies through end of America. What are these other challenges that we are facing with regulatory challenges or compliance and can you bring a different perspective as well her happens >> Angela Tong: This is the time I was staring at my phone First of all promoting regulatory compliance I think also this might be the challenge that the whole blockchain space

is facing, and also is.. The O should have a regulatory system that belongs to itself. in China we just abandoned everything, but for now, like China and other countries there is no regulation or everything is like shut out, so even if there is a regulation like maybe in America or in other countries for STO, it usually has to comply with the existing securities regulatory system, so in order to develop in a help healthy way, the government is pushing legislation that assumes is assume STO and is.. The O should be more frien friendly to individual investors >> So you think perhapsing being accredit id investors you think those should be changed so it can be open to more people? >> I think it should be more people but the knowledge of what is a security token and they know what is a security supposeen will bring suppos a security token will bring to them >> Drey Ng: I degree with what Angela said. Most can communities are yewsing existing framework to govern existing securityies. In terms of governing the new technology they ma bring in more risks to those types of security. The hurdle for regulation is not from the countryside but from the issuance side. There are not many STOs so far and the reason being for that situation to be happening is because it’s really hard for issuance platform to govern afraiding govern because most people in the U.S. think that S. The Os has been happening and if you think about primary distribution and secondary trading, think about the landscape and countries in Asia. You need to obey or be client with all these countries. a good issuance platform is important because it has to be able to connect with different external legal council s to make sure that the second dare training and primary distribution complete with the laws >> Say I’m baseed in the U.K and I want to buy a security token, Nash issueed one and whose responsibility is it Tokyo ? P >> The issue issuance types of regulations should be in forms of — law. Depending oh wherein where you contribute, for secondary training combining the buyer’s jurisdiction and the issuers because the buyers get protected from their jurisdiction. In terms of tokenization it will be both >> Everything that you mention applyies to the U.S mart and same problems we are having. That’s what makes it really complicated because regulation is the main obstacle to prevent all these STOs from

launching. As a U.S. company you care about U.S. laws but you want to sell to Novembers investor based in Asia and they want to trade with an investor in Europe. It is technology supports all these things but make what makes it hard is the laws and governments move kind of slowly and calculated. That is the main Hurl that Hu hurdle that we need to we face. Don’t have a solution I >> I think if he is saying the technology exists, I assume it exists in blockchain >> Waldemar Scherer: I think something that was lightly touched upon here was there is a problem with lack of information and youris Dix your jurisdiction s moving slowly and I think there is a lot coming out. If it’s other countries that are coming up with more STO friendly regulations and the U.S. is waiting to see what would happen as well is Germany, U.K., etc We have createed a virtual digital asset ashrine where alliance. We are talking to liquidity providers and KML providers and to the issuance platforms and we are understand ing different projects from different reamings and different jurisdictions have a better understanding of what is going on in terms of the local laws At the end of the day the tech is there, but if we are createi ng a standard, everyone is focusing on the same one, two, three, or four concept at the end of the day. How do we translate this into code and into a technical standard, and I think just bringing all of these people together and we have already seen it, we have people from Europe, Asia, and talk about what is happening in their region region, that is will help us prove this forward. If forward >> With those regulations being put in place it creates a precedent to follow for certain things is there a danger that things like ICOs will be viewed as securityies and I have known there are things in the dot-com boom and people were given things for free — >> I can talk from the United States perspective. I would say the FCC has done a few actions as in seen subpoenaing projects that have done it in a questionable manner. I don’t know if they are trying to make a statement, but so far they have only gone for projects that are complet completely like Frank lent. fraudulent. They have gone after products that have done good things. Tor fair there isn’t clear laws in the United States yet, so I would not expect regulators to come down hard on a blanket of projects but by coming down on those that are obviously fraudulent. ICOs that happened in the past, I would say in my opinion they would be gathered in grandfathered in. I don’t think it would be worth it to go back and press charges. They were obviously malicious. Everyone is just testing out the technology. In my perspective not everybody is malicious, so I would give the benefit of the doubt and give those early aCapitollers some freedom

>> That makes perfect sense Moving on from that, one thing that interests me is what role the media has to play being a writer and reporter. We have a lot of swing that in what we get to correspond. I am conscious to bick pick things that are global. What role do you think you have in educations people with STOs. >> Angela Tong: In China we can’t mention any STO at all and we can only report about how the situation in here or other countries. We want to provide knowledge about ICO and the if there is air crop drop of any projects to ICO by ICC, so we can just help projects to know about that in the U.S. We want to tell everybody people and like decentralized these is like important features in blockchain, so I still have the find a balanced way to decentralized and the central ization, and we want to help like our readers and our clients to know how to do S. The O in maybe other countries because you know China >> Did you want to add something >> For the other eco sim players I believe much like applicant republic and lick liquefy we would be happy to work with the public public People are still confused about it, so I feel there is lot ot education to be done I believe that in the future everything should be or will be tokenized. So the sales have to be well educated at the same time >> I think we are running a bit short on time now, but I just wanted to one last question out to everyone if if you want to take a few seconds to answer STO seems like a complex topic one geared towards transaction additional NSPCC traditional NSPCC tors investors. So say I don’t care and we don’t care how the banks do their thing as long as our money is there. Who should be the ones caring about STO, is it one t? >> Waldemar Scherer: You have people who are always interested in investment, work ing in the financial industry or people always attracted to different types of investments, yes yes, they should be interested and following and checking out what is going on because that is kind of their thing just athey have been following the stock exchange When you look at the blockchain technology coming together with this, that’s another sub community and I think it’s interesting from innovation perspective. Allow we How are you using this technology to combine tech and finance. Yes, everyone should be interested in that just like people are read ing what’s going on with AI, and VR and not everyone is playing or using these devices but it’s interesting as a topic If you have been doing invest investment and you follow the

markets because that is your thing and why not, then, yes, you should be following from an education perspective and how you could participate in this in the best way >> Blockchain and to Ken tokenizeing assets and because you are unable to unlock liquid ity for things like games or maybe housing in a city very, very far away from where you live. That is something that you can do with STOs and tokenizeing access. The most secure personal in the world they could trade on it today because you are limited to NASDAQ b wu STOs you can c co tennize everything. te colonize >> If everyone cares about this, it will bring us more readers >> Thank you so much for your input. I It sounds like it will be complicated and confusing and we all need to keep read reading and educates ourselves on the topic. Put your hand together for the great panel there (applause) >> Since we are running behind, we are going to leave the chairs here. I would like to bring >> Alek Tan: To the stage. He is the CEO of InnoDT >> Alek Tan: Hack in there guys while I talk to you about fraud, hacks and scams What you are seeing is things that happen in “Headline News” where we read from coin time or coin telegraph. A lot of things have two types of prongs. You have the customers at risk and institutions that are at risk As you can see some of these labels customer examples can include what we have seen or all the ICOs and then for institutions you have fake identity occurring on their platform, look at exchanges, fake accounts. Now, my theory is a lot of these KYC process where you have to scan your passport, take a selfie, write a name on it, put a date. You can use your relatives, you can use your passport you bought on the dark net, so matter how much analytics that you put behind it is that really true that you are try tied to this address that you are white listing. That is one of my theory. When looking at how much demand in this space , you can see on the chart, we have a lot of ICOs that are just blowing out of control and we seen in in 2018 as well and there was a study with Deloitte 1,000 reupon dents den 1,000 Respondents and 78% of these folks saying they feel like blockchain it’s an advantage we can bring in but 39% is there is not a lot of clarity or visibility for them to build a business case and push this product forward to implement to their company. We serve in term s of transaction studies, we solve these characteristics. We provide the macroview, micro view of transactions. You can see behaviors that go behind it, transaction gaps, fill or failed We can make transaction trail transaction trail there is certain data that happens behind these transaction

s. Doesn’t matter about the IP or the passport identification, it’s transaction digital intelligent device. Where InnoD T we lock at ripe currency ex changes and we try to push this community forward. Traunchs are on a ledger that you can’t change or manipulate. IDs maybe you can One example is visual lie the macro and micro transaction behaviors. You can see money going in and out. From a macro perspective you can start to bring in mapping capabilities and understand these relationships between tall addresses The second piece is because you can look at it from a macro perspective, you can have early detection. Look loose like at one than that has been ineighty enactive for a long time. In terms of these constant patterns you have these digital identity that businesses would be interested should there be activities activities, so we can start groups this into user A, B, C, D You can start applying these type of studyies and molecule mod you’ll modules how you look at history can dictate future habits Another example is relationship between two virtual. If you were curious, what is the most direct path you were keeping this history going. If you want to go user A to B to C to D That’s the most obvious, but what does all these other transactions mean? You don’t know when you are using a blockchain explorer to understand all the letters and how they move around, but at least component you have this tool to visualize your traunch Here is a second example Remember I was telling you about the K.YC portion in terms of opening up a new account. You have an address your interacting with your friend and you receive funds from it. As soon as you want to take your fund to ex change like Bittrex. They would have to identify the source of fund. Is this something that I can accept. Are you part of a money laundering scheme or where is this money from somewhere that was ran some ransom where and this is where they can verify that your fund are safe or not safe. Remember that whale wall address example They can be quiet for a long time and then all of the sudden he is not watching his address anymore, but as soon as there is activity you can have alert that says hey, there is something going on as opposed to watching for a few hours. You can get the instant alert right away There is tools that we are providing. When you look at this entire map of traunchs which we have 10,000 NEO traunch s in this example. You can see there is something going on here. We are going to give you the tools so you can do your own stud does doe Dee studies and understand. We have three different products here. One is for the enterprise. the other one is for the consumers and we have another education program that does a reputation scoring system My name is Alek and I am one of the founders, and my buddy is a

programmer. I handle a lot of fundraising. This is my history back in the corporate world and we have also for you guys to come and sign up for today to try out our dab system it’s invitation code only, and here you can contact us on our website. If you would like please fill out the survey, and we would be happy to address any questions you have. Thank you, everybody. Good luck (applause) >> We are now down to our last speaker who unfortunately could not make it. Some issue fire in a cockpit, he is okay, I am talking about Dr. Brad Mattson. He has recorded a video for us that we will show right now >> Hello NEO community. Thank you for sticking around for my presentation if you are still there. I had plans to come to Seattle, but my plans fell through due to circumstances which I couldn’t control, I am sitting in my hotel room in Louisville, Kentucky right now I am a practicing radiologist and after work on Friday went to the airport, and there was snow that was coming through the area , and we got on the plane plane, and we waited on the Tarmac for like an hour, and final finally the deicing truck showed up and deviced the plane and as we taxi ed out to the runway, there was a fire in the cockpit and we had to evacuate the airplane Normally in situations like that , I tried to keep my cool but I have to say I was getting a little bit nervous when smoke started to fill the cabin and what didn’t help is that I was at the back of the airplane and we were evacuating through the front door and there were people trying to grab their luggage out of the over head compartment, and I was thinking to myself don’t worry about your bags when the plane is about to explode, but anyway everyone made it out safe and we went back to the terminal and waited there are for about six hours, and all of the flights that were going to Seattle were booked and the earlier one I could have made it was on Sunday I would have made it there about noontime on Sunday, and I would have six hours and then had to turn around to go back because I have patients SQLed for procedures on Monday at 8:00 a.m. I will briefly update you on the project. It’s going well. We have a team of four physicians We have a PhD in biophysical chemistry. We have a full developer team. We have a team that’s helping with community, and I will admit that we haven’t been keeping up with the telegram as well as we should and that is somewhat intentional because we were trying to focus on the product and not the community and we really don’t like to release news to type anything. We are under the impression that we have to get a solid working product out and functional in severall hospitals and that the hype is just not going to do us any good. We are trying to get a medical encly encyclopedia out in several hospitals and we are starting with the country of Georgia, and Georgia because spot spy coin is based in Georgia and we met these guys back in September, and they introduced us to the health ministry in Georgia, so the medical encly Kloe peed yeah is basically done and now 80s matter of signing contracts with hospitals and the only thing that we have left to complete is the authoring tool that allow allows physicians to

edit the existing articles and guidelines and also create new guidelines. Aside from that, we have been working on an electronic medical record and if you don’t know what one is It’s sored sort of like in any hospital or clinic that you go into your information will be documented in an electronic chart, and an electronic medical record is the thing that stores this information. There are hundreds of them. It’s always surprising to me that there hasn’t been one market leader that has dom name. dom name dominated that particular market, but there is a lot of politics involves. Every countries that their EMR and the United States the leadingE MR is epic and probably second is — so we are developing an EMR which we hope to integrate with the medical sen cly Kloe peed yeah, integrated support built into the EMR. The EMR was something we started working on before we started working on the the medical encly Kloe peed yeah because we knew it would be a much more challenging project it is a complicated process building an EMR. Anyways the first country we are going to use it is Georgia and then we will test the authoring tool and the difficulty of translateing articles and guidelines into a different language in Georgia because Georgia is not as big of a country as other countries, then we hope to bring the product to China, and that will also depend on the regulations in China and we will have to hopefully participate with the government, maybe we can launch the project a research project in a few major hospitals in China first to get our foot in the door and then later convert this into a commercial product in China The long-term goal is to get the product into the quite. The United States. The United States is if you are trying to have a profitable company in medicine, it’s still better than any place in the world. To do that we would need to create content which fits the recommendations in the United States, so every country will have their own recommendations Some countries have different diseases than others, they will have different treatments than others and different treatments that insurance companies that they will pay for in some countries and they won’t in others, so it’s complicated. In every country you go to you need to adjust your article article articles. That is the complicate complicated part of this. If you remember our project a year ago it was called Bub hr atlas. It would function similar to a Wiki where people would create content and then be reward rewarded in the form of token and by redeeming continuing medical education credits, which doctors need to keep their certification up-to-date, we were going to receive our profit that way, and we will still do that, but in addition to that, we have changed the model slightly and we are going to start small subscription fees for use of the medical encyclo encyclopeed media encyclopedia but not what our competition would charge which is $500. We will try to keep it

lower than that. It’s been a busy year. We visited nigh Nigeria Nigeria. Their place that probably need a medical encyclo peed yeah. It’s more difficult to bring the project there because they don’t have reliable internet wherever you go. That is something that we are going to continue to worken work on, but not bring it there just yet We are going to focus on Georgia I traveled to Malta. I traveled to Italy briefly, which was main ly to meet people interested in investing in the project I guess that’s about it. We will try to keep the telegram community better updated on our progress, but I want everybody to be assured that we are making excellent progress, medical encyclopedia is basically done and we have a few more contracts to sign with people that are supplying the content otherwise I would release a demo URL for you right now. Just wait about a month and we will post it on the telegram and later on this year, we hope to have a basic working EMR: Integrated the medical yeah yeah — so again I’m sorry I couldn’t make it. I hope you guys had a good time. Hope to be there next year and the NEO health project is going well Talk to you later, bye >>> You guys are going to have clap louder than that for him to hear you in Kentucky Congratulations to bringing it to the end of the conference. I would like to bring up Zhao Chen He is the general manage of N GD Shanghai >> Zhao Chen: Thank you for being with us for two days Before we go and before I forget something to mention. There are three projects doing air drop and each participant with leave your badge at the registration desk when you leave and instructions will follow. That is all I want to say in terms of the air drop because I know scam mers will use a lot of Twitter stuff. That is all I want to say go to the desk when we finish. Coming to the closing I think there is so much to say, so much I want to say. Sorry I made a quick script. Let me practice. I am going to say some names. You know English is not my native language. Vitor, Ashley, Fabio, Tyler , Erik Anthony, Ethan, Alex, Jason — that’s the fester part Okay, that’s only a very short list of the names that I can find easily within our communities who are dedicated and true belief believers and contributing hours and days per month in one or two years to NEO That is a very short list, but it’s not all of of our community developers. How many developers are still here? Can I see your hands please? Thank you very much. Have you looked into our GitHub? I think you guys are missing some very important discussions. A thread

is 570 something Go back to check it out. Neo one, NEO more than that , we look forward to seeing more and more developer communities build up Remember to follow Twitter. The Twitter is NEO blockchain. The first presentation I asked everyone to closure eyes. I will not you to do the same. Right now I would like to ask you to open your guy eyes and look at the faces around you who stayed here These are exact exactly the faces, the people, who are part of our communities trying to build it up an build it even stronger. Last night, it was a very late video. Some developer s sent a very interesting developer love from Seattle to Eric. I would like to mention that so some of the people can have it echo. Last Lastly, I would like to extend our thanks to all the hotel staff PSAV and all the working teams who make this conference successful and make this happen, and thanks to our Emcee Ted and Harry, thank you very much. Now I would like to welcome the whole NEO team on to the stage and starting from John and Peng, would you please? Following long Phi Follow ? Longfei, — come on to the stage, let me see you (applause) Charlene, Tamar, grace, Peter you have taking a different route. Dennis, Sara, Lemone, finally Hongfei where are you? (applause) I think probably Eastern think probably everyone has met with the team, and I expect you already know what we are up to Hongfei do you have more word to share with us in >> Let’s do it in to 19 Let’s make NEO the best blockchain in the world (cheers and applause) >> Thank you, guys (cheers and applause) >> See you next year even if I don’t know where it will b be >> Probably Europe >> Maybe >> Maybe I don’t know Thank you guys, thank you Thank you (applause) Sorry, photo where is our lovely photographer
