Retour sur EthCC 2018 chez TalanLabs

So hello everyone, I'm Jimmy Ragozin, a member of the CE (Centre d'Études et d'Informations - Centre ... Also, to retrieve the presentations from the SELA 7 meet-ups, so the Rome Community Conference, which has been the largest European conference to this day, took over from the Delettes Community Conference last summer. The "L'Homme Developers Conference," which was organized by SETTE last year, was somewhat hijacked, and now it's held in China, so a new name was found: "Les Théorèmes Community Conferences au Canada." The next one is in Canada, but it won't be in France anymore. So, a new event is being organized by A7 at CNAM on March 8th, 9th, and 10th, 2018.

It's a four-year parallel event, so there were over 800 people there: 130 speakers, 650 participants, many invited students, and volunteers. There were a huge number of presentations. I'll try to give you some feedback on what impressed us the most, but of course, we won't be exhaustive. So, if you have anything to correct or add, I wanted to do a small survey in the room. Present at the trial, it's already happened, so I invite you to participate and complete at the end if there are things that stood out to you, and also to see the level of the audience who has two or more tokens in the room.

Very good. So I want to warn you that if you went to Maya Terre or the help section this afternoon, you may have lost everything because the DNS was hacked. So it redirects you to a copy of Magneto Wallet which will steal your private keys if you didn't have the Doua Voile. So if I see people running out of the room now, I'll know why. I wanted to warn you.

So one of the topics will be security, which is still complex to manage. So the three of us will give you feedback on these different topics here: what stood out to us from the point of view of protocol, identity, scalability, and so on. And we invite you to participate and ask questions or add to this if you watched the streams or if you were present. So it's 130 speakers, 130 presentations, what is it? that they presented to us in the general theme I like.

I noted two presentations: one by Yvan Jeunesse, who is now at Consensus, and another by the person who does a newsletter, yes, which wasn't Rome, which is very interesting. I invite you to subscribe. It summarizes a week of events for you, and on Thérèse, men in an easily understandable way. So I invite you to subscribe. He gave us a short presentation on the current state of token models, which began with a history of tokens.

So all the first cryptocurrencies, Bitcoin, MasterCoyne, and so on, which were rather, therefore directly mineable. The first wave of tokens, with the first tokens, was a man like Augure Digix Maker, who had fairly similar models, but a small share for a foundation of developers, etc., of the project, and 70% distributed during the SIO. Another wave where we started to see depressions and bonuses appear. The earlier we bought in the year, the more tokens we had, so it was already starting to become less egalitarian.

A third wave where we have Given the initial sales that concluded in five minutes, or simply people who had created scripts or who had nothing better to do all day, managing to acquire tokens, we saw attempts at a German auction to smooth things out. However, this meant that it was mainly the large investors who were able to grab most of the tokens, so not the best model for distributing the project's tokens. A fourth wave followed with huge reductions for the early investors, resulting in a deficit for the large investors, making things even worse. He then gave a brief overview of the future and what is driving this. He said we will see the emergence of many true security tokens, which will be considered as such and will therefore need to comply with regulations.

These will generate dividends, for example, with the real estate sector. He also spoke about projects whose model he liked, such as contribution tokens. As a variable, we have Nathan here who can answer your questions, but who is offering this to real users, beta testers, and others. who promotes the project of earning tokens, so the rates that they are really distributed to people interested in the project, participants who may be led to change in the future, the token of the Ecofont project says that it does something similar, so a model that seeks to distribute the tokens really to the participants, to the people involved in the project rather than to the biggest investors. Another interesting rate was from Rick Dudley, one of the people who was there from the first summer meetups in Rome with the Corps team.

He worked at the beginning on the development of virtual poker apps in Cairo at Consent, if it wasn't called that yet. He is a consultant for many companies. He came to talk about what he is, but not for the sake of the summer meetups, even though in the end he said that he liked many things and that there were very few things that he didn't like. But he said that at the very beginning, the Corps team wanted to do a little bit of everything at once, wanted to be decentralized, efficient, and secure, and that their architecture, their first architecture, was Not perfect, and they could have consulted more experts in decentralized architecture and decentralized systems that existed in other fields, but they wanted to do a little bit of everything. There were some errors, small problems in evaluating the price of the gas that allows us to make our transactions and run the applications.

So it's very difficult to evaluate this gas price, which is why when we make transactions we simply stipulate a maximum limit. It could have been done differently, according to him, if we had thought about the problem better, but it will improve a bit with the transition from the summer to the Rome Virtual Machine to web assemblies. It's also very complex to simply calculate the balance of a account. This is an idea of ​​how the architecture was designed, because if we receive ethers on a transaction, or if we mine them, they don't end up in the account in the same way. We have to take both things into account, and therefore all the applications have trouble simply knowing the balance of an account, and all the governance problems...

We know there's a bit of centralization around the foundation and around Vitalic, who, even though he says he's not really at the head of the project, is culturally ingrained in people's minds. All the problems, especially around the OIP 999 Leaf, which was locked due to bad code in a sports contract, raise questions. Are we going to recover the funds? Does this mean the blockchain is no longer immutable? All these questions came up in this general theme, which really interested me.

The Lightnings Tox was a series of presentations for all the latecomers or people who had a very small project to present for two or five minutes. Many projects were presented, notably Crypto Cup, which will give us a very small demo later, not right away in the presentation. So, I remembered Guette Solide and Hip Hop, as someone who makes a site that wants to document all the smart contracts and Terium. He made a script that retrieves the data from the blocks, which then outputs the code. He dressed it up like the abbey and invited people to come and document it and show how the interfaces work and everything.

There's not much in it yet, but I think it's a good initiative. Vincent, the Gallic, who is hidden by the small photo I put in (which I misplaced), was present in the room. You can ask him questions too. He presented his project, Charity Tschaen Point You. He mainly talked about how it's a little difficult to learn to develop on [platform name].

He was a man who realizes he doesn't know much, but the community is very friendly and helpful. In all the myths up [platforms], you can talk with people, and therefore it's very easy to develop skills on it. Clown Factory was another project that explained that for all the large contracts that require a lot of resources for deployment or use, they found a technique: to concentrate the main logic of the contract on a master copy, then to create proxy contracts that point to this contract, which are based on and function from this contract. This means that all the small deployments of proxies involve very little code and consume less resources, and the transaction functions consume less, so it's very interesting for people who need a high level of scalability. Then, to move on to another topic, the topic of identity and data, we've had a lot of presentations on this as well.

We know it's one of the most interesting use cases of the summer. We're working on one of the biggest projects you might know about; it's Hugh Porte, who's trying to create an open, decentralized identification platform for the web. So, if I had to simplify, it's about replacing the little " Log in with Google" or " Log in with Facebook" buttons that are starting to proliferate on all websites with a solution where you own your identity and your data; you do n't give it to Facebook. You know very well what they do with it; you've seen the news. So, it would be a project, a platform that would allow you to register your identity on various websites and choose what type of information you share.

That is to say, my entire identity belongs only to me. I was going to give her the private key to my account, my identity, and she quoted me. I want to give her my name, my age, my date of birth, my CV, maybe my health record because we're talking about a doctor here. So we choose which facet of our identity we share. It's very interesting; it allows us to regain control of our identity.

They are open, meaning that here you go to developers/support. You can try to interface your application to identify yourself with Newport, which allows you to remain in control of your identity and not use third parties who do whatever they want with Kiehl and monetize it. So then there were many very technical things, a multi-layered architecture. They want it to be used on both blogs, private and public TechNet channels. They're going to have a standard protocol, version 780, to have a registry of identities, and the complete identity will be stored on IPFS.

So they were also centralized on Glider. We had another presentation, which is a bit like the counterpart to the gateways, but on the data side, we're talking about It's not just about identity here, but about all the data we leave lying around on the web throughout our lives while browsing. So, the point is to establish... The architect Claude Chêne is someone we can sense is someone many people know because she participates in many myths. From 2 to 4, she explained that in Web 2.

0, we don't own our data; we leave it everywhere, and it's Google and Facebook that collect and resell it. So, she's looking for a solution, and with the Ligne à project, she's trying to create a decentralized platform in the same way, so that we can store and control our own data and share it, even monetize it for projects, but so that we are the ones who receive the reward for sharing our data. She talked about longitudinal data, that is, all the data we leave on the web. Identity is part of it, but so are the types of sites we visit, the things we buy, and so on—these are longitudinal data. We'll come back to that, but there are many user experience problems to overcome to create something that will see widespread adoption.

It will have to compete with today's simple, centralized solutions. And what's interesting, if there are any developers here in the room, is that they launched a bounty program to develop a first date on this platform. It's definitely a hit, so it's yet another site that allows you to directly respond to a bounty and win ether, but they're also recruiting a lot. That's the identity and some key points I've had from other presentations that were interesting. Well, that's the lot, perhaps.

We had one on the Swarm project, which is a decentralized storage platform. It's part of the great triptych of the decentralized web and theorem. So we're here, blockchains to run decentralized applications, Whisper decentralized messaging protocols, Swarm to store data, so a decentralized Dropbox. So we're scattering the data across many names, on complaints, no, the numbers, it allows us to retrieve them, so they're making good progress. They have a third package released; they also have a messaging application, a file system extension in user space, which is an equivalent of barter, and it's starting to work.

So, interested parties or your projects? Bloc Heidi is a French project on identity; it's the people at Octo Technology who developed France Connect. I know I use it; it's a system that allows you to identify yourself on all French government websites. So, if you already have an account to pay your taxes, you can use it to access URSSAF, health insurance, etc. You can connect with an account at the post office everywhere with your tax number.

They want an interface, and that was with Rome. So they made Bloc Heidi, which allows you to say that an address belongs to a French citizen, and it could be an interface between France Connect and Terium. You could associate your France Connect account with an address and Terium, but we can imagine all the possibilities after that. And lastly, the N S and es men don't like service; we know that addresses and men In hexadecimal it's very complicated to type and copy and paste, so there are services that allow you to bid and win names like website names, but they point out what corresponds to our address. So, for example, I have a giragos address, appoint ems, which allows me to send ethers simply by typing my address, giragos, a period.

These periods, the thc, rather periods, were completed, giragos, a period, and th, which is much easier and avoids errors rather than a long string of characters. So they say that their adoption is growing rapidly. When you type these names on my Tamas, on exploits, a block explorer, it works now for most, and they are trying to improve the process to obtain this address, which is still a bit complicated for newcomers. I'm going to give the floor to Fabien, who will introduce himself. Good evening, I'm Fabien.

So, the topic that spoke to me about topics that will interest you, finally, that I'm going to give you a... A small report: it's the diversity of its 117 features, which is a new standard of the AutoCAD type for 20. So, the idea was to offer new ways of doing things. A serious look, we already have a few, but the RCV standard has already given some problems related to the fact that we can't send tokens, sorry, excuse me, Samuel, can't send tokens on a smart contract. Interjet Avant in a simple way, so they directly offer a new way with also the fact of directly specifying 18 decimal places for targets.

Sorry, I see, you have eighteen decimal places and that's it. On the ground, on the token, it's not a different type of decimal that we can see on other types of tokens. It's also possible to make hearts. It's a little tighter, extensible via a hook system, so you'll have to have a little bit of knowledge about how these things work with the gold on their site. Another topic that I found interesting was Highway Samse, the cell of web use in its bed on sure and Terium.

Why, why, why reinvent the The wheel, actually, because today Vermont has some issues related to the fact that, as I mentioned earlier, they have very few languages ​​currently available on 7 on 7 Stack. We're going to reuse the community's know-how and work by finally using Web Assembly and Terium. So, that's what I took away from this. When we cover a lot of topics, there are no questions on these first points or other points for those who were already there. We'll continue with a short interlude to tell you that the trial is what we're presenting here.

It was mainly large presentations in the lecture halls—four lecture halls running in parallel—but there was also another room where there were workshops in smaller groups and real work. So, a very remote room, very difficult to find, it was hard to get to, but when we got there, there were some interesting things. The biggest thing that came out of it, I think... It's a bit like the creation of the group, the Summer Magicians Community. So it was the big bearded guy who did it, we understand why he's a bit like the Gandalf of the community.

He created this group, so it was Greg Colleville and Jamie Pitt who proposed it, to gather best practices. So it's all those who work on the Higuain Protocol, the clients, and it's the big names of Summer Magicians who created this group to meet up at the various conferences. But they also created a website, a forum where they can continue to discuss their goal, which they defined together. That Kate and Rome remain the best possible technically, they want to foster community consensus on the technical direction and the summer specification, so we encourage all discussions on this and have an effect. Ray Home Improvement Proposal: proposals for higher-quality technical improvements accepted by community consensus.

So perhaps we should consider improving the IP acceptance process. This group talks about very interesting things. You have their brand new website here if you want to participate in the technical discussions; it's very interesting. There were others, see shop, and others. There was a Wolf game with Terium; I took a quick look and found it funny, but I wasn't at the workshop, so I can't say much about it.

There were workshops on the development stage, how to use the toolkits, Remix, etc., and workshops on game theory. It's interesting. I noted workshops simply on Python, so for the devs who were interested in all this, and the Terium Community Conference 2019. If you are interested, you are a developer who does n't want to see that...

PowerPoint presentations are very interesting, and participating in these workshops is a big deal. The big surprise of the community conference was Vitalic's appearance, which he hadn't announced. So, after a bit of persuasion, he managed to get a small slot in one of the lecture halls. I'd never seen a lecture hall so full. I think if there was a fire, half the community would be dead.

(And sorry, it's true, there was a fire, we should n't have told the insurance company, and everyone was on the stairs listening to him.) He shared his new Plasma Cache specifications. After a few jokes, he offered to share 5,000 and 5,000 of them, of course, if we sent him some first, like he does on Twitter. And the second joke: why Plasma Cash? Because it's plasma, but more than that, it's beautiful, as Bitcoin Cash seems to suggest for Bitcoin.

I won't get into that debate. It was very technical; it's difficult to go into detail for those who don't know. Plasma, in three words, is the act of creating child blocks of a root block chain, which would be that of the lands. In this chain, we would have tokens, a point with what circulates on the root block chain, and with marquetry systems. The fact that everything is stored in the parent block chain ( excuse me for the simplifications for those who are very technical here) allows us to be more than just beautiful because we can have many blocks in the child block, even several levels of blocks in the child block.

And on these child block chains, depending on the use case, we can use consensus protocols. It's a bit more than just beautiful, less secure, but as Authority proves, and that's where he invented an update for plasma: Plasma Cache Cache. Each time, we would have seven concrete block chains, and it's suitable to duplicate tokens a bit. A root block on seven blocks in the child block, this time a token with a non-fungible and non-divisible Heidi, unlike plasma. And that means that when we go back and I rechecked all the transactions that have passed through the plasma tree in the root chain.

Before, it was necessary to check the entire tree. Now, like with Heidi, we know that our tokens have only been used and exchanged in certain transactions, so only in certain places. Merkel Trion only has to check our own leaves of the tree where our tokens were changed. This makes it more elegant and has other advantages, notably a complaint system. If our tokens are moved or stolen and we disagree, we will have the possibility to recover them.

One example that illustrates this is that even centralized exchanges of the future will be able to ensure that we retain ownership and private keys of what we have deposited in the exchange account. So, even if the exchanges were hacked, no one would lose their open tokens thanks to this plasma cache system. Because before they actually leave and return to the block, we would have had time to file a claim or complaint, and they are saved. There was an excellent presentation, so like the comment, the amphitheater was full for Vitalic. There was his mini- me, his friend, because the river had gone on the stairs outside in the rain.

The summary of the presentation for those who weren't live was excellent, so it was like a physical stream. He then gave his own presentation. There are versions of it on YouTube too, even before they made it. Aleph CC of plasma and char ding. He had removed the Casper chapter because it was too long, but it's an excellent simplified explanation with lots of diagrams of what plasma is, what char ding is, even plasma cash.

If you watch the other presentations, you'll see Casper. I find it the most understandable for those who haven't necessarily been in the field for a long time, so I invite you to watch this video. There are links at the end of the presentation; you can find it there. There were more technical, more advanced presentations by Ben Laden Fille, who presented Casper for the tech proposal, but the correct version, not construction, so crowd proof of state and He explained how it could work so well with the ch harding casper cbc, so it was quite complicated. He also had another discussion about governance, where we actually spent two hours on his definition of governance in one sentence.

Interesting, but it almost went into philosophy, high- level semantics. In this case, well, Ali, then scalability, lots of things, especially all the projects working on their own Kabyle identity, working on implementations of Peamount, Channel of Shame by Steve Chainel. You have everything that is Cosmos, so blocks, blockchain, chain. It was presented at the last meeting, so I invite you to find the presentation in Slack to learn more. Raiden, so the equivalent of Lightning, let's say of Bitcoin, but for the summer, the team is making progress on its Channel stats.

For now, only Micro Redone is working, so one-way Channel payments for one person, but they are making progress on the rest. So, a lot of things on scalability are progressing, which I invite you to look at for yourselves. We're moving on to what is perhaps the most telling... Cadets use the eydap, I chose a good one for you, so take it. Amine Soleymani told us about spanking.

In this case, the spanking balls, chains, which I think was the third day, he woke us all up because we were starting to fall asleep, starting by saying, "We're told about a man who masturbated for the first time at five years old," so it was information we all needed. Very beautiful too, he had a dressing gown, a bit Asian like yours, I liked that too. So he came to present us with a decentralized streaming application for people over 18, so it's an application that aims to decentralize webcam sites, Heuzé webcam hours x kiki, so those that do live performances with a chat next to it, the possibility of giving tips. So he gave us the example of many actresses and webcams who have their bank accounts closed or their PayPal accounts closed because the banks or PayPal don't accept to linger. In this kind of environment, it's very good that it has uses for decentralization; they can be masters of their money.

So they have two tokens, the SPANC and the Boutis. Very good, too bad, one for pure steak and one for tips. It's more complicated than that, but I simplified it. They tried to involve the minds of the viewers, the users of this open in the system because they will randomly check the identity of the webcams, even verify that they are over 18, and that's partly what it's for. So the fact of being able to steak and earn a little reward for doing this verification, in particular, they made a superb Crypto Tease application.

So for those who know Crypto Tease, instead of collecting cats, you collect pictures of breasts, and in fact, it was for the onboarding of the dukes or the webcam users so that they learn to use the applications. They said if you put your picture of Saint Cyr Crypto Tease, we give you so many men to dig up. Let's get started, and we'll guide you, explain how to install the application, and how to retrieve everything. What's particularly interesting about this project is that it's very advanced. Scalability is limited, but it's hard to say.

They already have operational Chainel payments, so they can make offshore transactions for all the tips given to webcam users. They've improved the user interface and the user experience. As you can see in the screenshot, when people connect to the site, they see something like a bank card displayed. They can load this bank card. Loading this bank card is actually putting ether on the Chainel payment, and this creates an image that resonates with people.

Using these Channelel payments can be a bit complicated; they might think, " I have voters, why can't I give them the data directly?" No, I have to load a Channelel. Here are the 10 BAT cards to load your Spank Chain card to make tips. So I find this very interesting for simplifying the transaction. It's more technically behind them.

They told us they even have a complete Steve Chainel implementation coming, maybe even Plasma. I didn't hear about it at parties, but the guy had a bit more, so I'm patient. Another interesting presentation was on budget DAPs for music, which would replace Spotify. Spotify and all the elites and iTunes are what allow you to get ahead and share your music. So it's been around for four years at Consent 6, it's evolved a lot.

He explained how it works, and licensing in the music industry is a bit complicated, but there were three pillars: you had to be able to distribute it, it's become a bit decentralized with the peak torrent, the worst part is all well and good, but you also had to discover artists and pay them, finance them. For now, it's not centralized or decentralized at all. Apple, Spotify, Deezer control everything, so artists are now able to know that their song is played a million times and they get 10 euros from it, so there's a big gap. They're starting to rebel a little. And so they're looking to decentralize everything so that artists can manage their own songs, their own artist page, and so that we can, with Ms.

[Name], hide the stream. Their music is paid a little per song, even per minute, for what we listen to, and the majority of the money goes to the artist and the actual technicians who made the recording, not to a third party. So they already have an Alfa [platform], you have the address here too. Here, we're using Meet Hamas, which you can use. So you can register as an artist, add an image, create an album, a single.

So their goal is for even the music to be decentralized, stored on IPFS a little bit everywhere, and you can earn badges when you're the first buyer of the album or when you 're a fan of an artist. And they want to use them for promotion, then private concerts. For this, the patch of your artists as tokens, all of this is very interesting. There's a long way to go before killing Spotify, but it's going well. Another key point, and then we'll have a short presentation by [Name].

Klepto Cup, summer, Roma, their Crocs, alarm clock, people trying to create a protocol that allows for scheduling transactions, ensuring they go out at a specific time or frequency. It's interesting, and we have a decade of fun using it to make the most advanced application in terms of decentralized casinos. What was interesting is that they also created their own Chanel-style system for their casino chips, and it works quite well. And then there are those who are trying to create decentralized insurance, like a long-standing alpha project on airline flights, but they have many legal difficulties. So they started with flight delay insurance in airports, and they want to gradually move into crypto wallet insurance.

They're attacking security like that instead of strengthening protocols and reinforcing security at the technical level, like many other developers are doing. They say that some people will want to take out insurance on their wallets, like, "If I get screwed, who am I in the stock market?" And it's not a bad idea. Insurance on agricultural harvests too. They have pilot projects on this with farmers.

If, following a hurricane, we lose everything, it seemed like a good way to be reimbursed, all the farmers would pool their resources. If they have agricultural insurance, then it's insurance that could be customized according to many parameters, depending on what we want to hear from clients. So that's interesting too. There are many other projects, but I've already made some myths. So, I won't go into too much detail, but you have the names.

You can find the video presentations from the meetups, and I'll hand it over in a few minutes. A five-minute presentation was done there. The Crypto Cup project was presented, which is quite interesting, a product that will be released very soon. So, we asked Lucas to become one. We'll give a short demo, a short presentation of this application.

Hello, so Crypto Coop, we're here to present a project that exists today. We presented it at ES6. If it was a PDF then, today it's a real project that exists on the network and Terium. You can test it right away, but I 'll give you a short The demo is on the Robsten test network, and the idea is very simple: it's a prediction game where you can predict the results of the 2018 FIFA World Cup by giving the results of the group stage and then the bracket. You'll see this in the video, which is really interesting in my opinion.

The prediction is yours, and it's written on a token called "No Mercy 721." So, like Rittaud teased, which you might know, you're probably disgusted. It's a token that is precisely yours and only contains your prediction. What's interesting is that once the first football match is on June 14th at noon, let's say, you can no longer make predictions since you'll have more information than those who made them before. However, a market opens up to trade predictions, which increase or decrease in value depending on real-life information from the FIFA World Cup.

I'm answering the question, the first question that always comes to mind is why, why not do this on the blogo chain, why not on Behring? It's because with Bwin, you can't resell your predictions as the information becomes available. So, here's where you'll find the presentation, but this is a link to the site anyway. The link works, so you won't see it today to avoid any disconnections. I've just prepared a video for you that I filmed, no more than 20 minutes long, but basically, what they want to talk about is the valuation.

It's quite good, and it's based on a real spot price. To buy your Kane rate with the prediction, at the beginning, it would be around $30. And so, cumulatively, the cumulative spot price will determine the valuation of your token compared to the evaluation and the real information from beyond the tears of the lakes, the FIFA World Cup block, and of course, compared to your prediction, you'll gain or lose points. You 'll see because Everything that everyone tells me can be predicted, and based on this position, you win or you don't win anything. So, words, times, I need a small browser on YouTube [Music].

So, there you go, Crypto Coop Pouliot, but you'll admit the link on the presentation. So, there we see tokens that I've already created, so CDH and Open with my predictions from a link that settles and some think Ian. I'm Argentinian, otherwise, but otherwise, you can start with Mike. My prediction is there, so you press, you give your predictions regarding everything, all the results of the World Cup. So, you can do this more or less quickly, with more or less awareness, with more or less fanaticism and passion, but basically, you need an effect, you have to give the results of the first 48 matches of the group stage.

So, there you go, it takes a little while, the video isn't long enough to like. There you go, it takes a few minutes, no more. And so, after the group stage, there's the next button that we click and link to The tree structure, based on what you have, is close to 10 in relation to your matches. So there you start selecting, it's no longer based on the result but just on the winner/loser. So you complete a tree structure, so here it's Costa Rica that will win, then Nigeria, Brazil against Belgium, France is added to the web, Germany after Brazil, France, and who's coming next?

It's true, there's quite a bit of France. And so on this, you create your voice, and all the predictions. And we also have, for the sake of differentiation, we also add yellow cards and red cards to prevent them from having as many tokens as possible that are similar. And there we build the token, so in our interest, we need to put a mask because we like Hamas to interact with the internal network. So, as I told you, today the token costs us $49 at validation, 20 minutes ago, but we're going to try to be more precise so that it costs at the beginning Approximately $30 for the first ones to buy, so these aren't initial amounts.

You're buying your token, but it's yours, it's not initial. So we're currently building the token with you, based on your predictions. I tried to speed things up a bit because it took a while, I think the network is a little saturated right now. Prices are rising, and people are starting to get help again. But basically, there you have your new rate, which [Music], and so there you go, it's yours, it's your Skis token.

And my interesting point is that, once again, once the first match is played, we can no longer make predictions, and one day we start to Playing in relation to leases, your exchanges, to value the tokens that appreciate according to FIFA World Cup information, so here's Crypto Cup, which I invite you to go and see for yourself right away. If you see any, if you go to the website or if you send an email to hello@cryptocoop.bio, we can also provide you with the information leading to a good bounty program, but the idea is that everyone participates. It's quite easy, and what we also like to say is that it's a real application that everyone, even your grandmother, can understand. So I invite you to get everyone involved because it's fun, after all.

Thank you very much for this presentation. Just before, I'm going to talk to you about something that is perhaps a little less fun in appearance, but nevertheless, it's necessary. There wasn't much talk on the aspects of using their chains in a corporate environment during the TCC. There were two, to be honest, there weren't many people there. Sheet metal, which is a bit of a shame in my opinion.

There was a Bart Baele debt that was doing a rate that had never been seen before. There were a few more people on Amber's talk, a few less on Jeremy's. We really don't know why, but there you go. So, it's important, so that's why I thought it was interesting to show this tonight. So, Hennebert, she already gave us a presentation on what the use cases are in business, on the right channel.

There's already the question of whether we need chain blocks, in the case of jazz, as we're doing. And then there's the debate between private chain blocks or public chains. We've seen a lot of DAPs, those based on public chain blocks, which is great. There are plenty of things, however, on the corporate side, there's much more interest in private chain blocks because we want to stay in an environment we know and control. However, there are many, especially on the other hand, in Rome, unfortunately, the limitations, both technical, trust, confidentiality, security, things like that.

Scalability, and so that's a problem today regarding the adoption of certain theorems, especially for businesses. Other points she raised with us include the integration of an existing business ecosystem: how do we leverage a new product, a new technology, how do we ensure that the new technology will integrate with other environments, the legacy systems, and so on, and how do we maintain all of that? So, these aren't exactly exciting things, but they're necessary. And today there's an initial response to this called Rome Quorum. It's a strong client gateway that was created by JPMorgan, initially by no bank.

The advantages of this good one are precisely that it tries to address the problems that currently exist with classic, abnormal themes. It provides privacy with a module called Constellation, which provides confidentiality with ADSL, so the SLCs. The implementation of the i-Kass Marx zero- knowledge proof, which has recently been implemented on the highly charged ROME platform in public, and there's also the possibility of having a consensus different from Propofol, particularly from Professor Authority. It's not the only presentation that can do this, but it can be done, notably using the Raft and BFT algorithms, which are very sophisticated, around Aphtes, which is very well-known and widely used for other systems and its predecessors. So, this reassures companies quite a bit when we tell them we're coming with a consensus like this – most of them are familiar with the second volume.

So, it was Jeremy Millar who came to present the related prize alliance and other platforms. It's a foundation whose purpose is, well, I'm trying to summarize it like this, to answer the question, basically, how to deploy ROME on a large scale in large companies. That is to say, today, when we have startups, they typically tend to start on public platforms, which is great for large companies that want to... They want to make decades of use from chain blocks, the trick is more complicated, so Amber presented us with a decade of use rather than a product. How do we technically respond to the time Jeremy Millar with within the Eee and they have a really more global approach, order address, how the rest is problematic there in order to transform it was really a product in place, grills, so that means a lot of things behind that and it also means, in particular, countering the competition.

I don't know if in your respective jobs you have the opportunity to see this debate, whether we were using ROMs or other products whose names I will not mention, but there is really fierce competition because it is happening because behind it it is business and it is revenue all that, so there you go, and so if we want ROMs to be able to penetrate these markets, these are their areas of application, we have to abandon the idea that there is a kind of foundation that oversees all this, which, in quotes, does not bring order but reassures everyone. When we say that, they're not really a foundation, it's something they keep focused on year after year on open source. They especially don't want to sell products or anything like that, unlike consulting firms. The goal is really to unite all the initiatives that exist, and in that respect, they have a rather interesting vision that's somewhat similar to Vitalic's vision. For them, in the future, there will be more private channels that will address certain use cases, certain business games deployed in companies, and the idea is that these private channels can be linked to a public channel in a way that creates a certain homogeneity in the use cases and the data that will pass through them.

One typical example is that someone, an average user, can have their personal information on a public channel, and then, depending on the services they consume from a particular company, this public data will end up on a specific blog or private channel that corresponds to the company providing the service. They need to be able to give up the ability to close The famous Diaba tap isn't given to Ben, it's over, 6th then service, so I'm taking them back. And so, if we have private channels that are linked together via this public channel, it would allow for this type of use. So how are they going to achieve this goal? Well, their first idea is to have an approach...

well, they've made an observation that there's a general lack of standards. So, it's a super boring talk, in a joking tone, but unfortunately, standards need to be created so that cotton can affect companies, on many things. So, linking it... in fact, it was created, I think, a year ago, maybe a little earlier, in that area. And in fact, they did that...

well, they admitted that they hadn't done much in recent years, so we didn't hear much from them. So, they made the observation, now they've taken action, they've found good people for the right positions to revive the momentum, and so now they're proposing a roadmap for... So this year, the goal is indeed to develop open-source standards to accelerate and improve the reliability of development, whether it's for new clients, ROMs, cheap UGG aperitifs (it 's around here), or other things that will come from standards for developing applications, the end of the civil code, all these things, so it's also important to have best practices on this. They're going to deploy internet access for all members of this foundation, so all the people who subscribe to the foundation. They're going to create a repository, a GitHub repository, all that.

It's in the list of objectives. There always has to be something easy to do, so there you go. I think they'll have to manage it. Normally, they're going to offer certification programs, so that's interesting too. He didn't really go into detail about how it would translate, what they're going to certify: people, organizations, or something else.

We don't really know, but it's something to follow closely. If you're a developer and you want to present yourself as a good developer, say IBA, it could be interesting to have a certification. Behind the scenes, they're going to do professional acculturation training sessions, so that's very good, well, in any case, it's great. There's going to be strong marketing to get the word out, so they're going to do... basically, I understand it as lobbying, and that's really something that's still lacking today, compared to the competitors who are also on the market and don't hesitate to lobby hard, so that's very good.

And finally, they're going to engage the community, all that, blogs and spinach, everything you can imagine around that. That's all I can tell you about the corporate facts, thank you. In a way, when I warned you, these dances are long, don't worry, there are only two topics, we'll conclude. So, to relax a little, I remind you that there are also after-parties, it wasn't just presentations, parties throughout the event, things a little more reserved for the speaker, but not just one big party at the end. I have Couldn't be there for everything, so if you're getting a bit fed up, imagine we can also grab a beer right after Semis Top, and it'll look like this now that I've got you back.

A super interesting topic: security and confidentiality. To get to the point quickly, Socrates, is this a project that offers a toolkit to implement the X Marc Surer Teom the Knicks Nate? For now, those originally implemented on this cache in French are an implementation of zero knowledge, therefore succinct proofs, said zero knowledge disclosure. I have the impression that we understand better in English than in French, even if we don't understand English, but it allows us to give proof that a transaction, that a process, has taken place, to be able to verify it without giving more information about the sender, the identity of the person or persons involved, information about what we are trying to hide. So he explained to us that in general, processing transaction chains allows us to improve scalability.

We talked a lot, but also confidentiality also means we hide Identifying them with chains, so there are many implementations, notably too fast to do all the calculations in a chain and avoid wasting a lot of space, a lot of gas doing the calculations. It was a man, and there are many implementations that are a work on heroes, knowledge proof in general, so all the proofs are knowledge disclosure via the ARX icons. So what we're talking about now are ICS and Stark, which would be a kind of input egg, Snax and Bulletproof too, because we're working on it. So before the spinach, it was only implemented on this cache for a short time, since Byzantium, on the very exciting road. We're there, it's possible on the inside, it's still very difficult, it consumes a lot, it's still very difficult, that's why they're trying to work on it.

By releasing this toolbox, it will provide a language to allow the use of these inputs, which mark this with things we recognize from other simpler languages, a compiler and means of verification to precisely check these Xmarks, and he talked to us a little bit about decade usage. So the The desire to prove you know a secret without revealing it, the desire to prove you belong to a group, could allow you to make a transaction to say, "I'm from here, but who I am in the set is unknown, so I can enter the Myth Up with my mask." The threads say, "Okay, well, it would be tokens, for example, paying 20 for any game, Tonsure Terium, but which would be in the transaction would be confidential." So, recreating the cash museum on a more anonymous cryptocurrency was more about confidentiality and security. I remembered the presentation; it's worthy of IS #6, #7, #10, and especially brand prediction projects.

So, they did their presentation on that, but it's not part of what we remembered today. But it's mainly one of the first to have implemented a good multi-signature wallet that is used by a huge number of projects. So, they presented the lessons they learned from this first multi-signature wallet, which has existed since more than 2016 and wasn't simply developed because they needed it for their projects. Marquette's prediction and there wasn't one, so they did it. As a result, it was used by a lot of Dahissiho to do their founding and keep the funds.

It's quite transparent; you can see when the funds are spent. There are currently three billion dollars stored in it, so people have more confidence in this hub than in Parity. I don't know why, but it's a little expensive to use, so it requires a lot of gas to deploy. Then, to make transactions, we can't give them anything. It's there; there wasn't a system that was planned, so it's the contract.

It's deployed; it's the only contract, and the user interface is quite complex to use. So they made a new version that they called SAFE. That's the logo we see here, with a new architecture and improvements. It costs less because they used something similar to what I talked about in the Lightning Toc: an architecture with a smart contracting master that, at peak, has all the functions. We deploy it only once.

It's expensive to deploy them, but... Deployment and then contract proxies and BAT. For some time now, we've had the ability to create delegates, so to point these contracts to a contracted master and call its functions. What does this do? It means that this small contracted proxy, which each wallet user will deploy, is called Bailly.

It's very few lines of code, so it's inexpensive to deploy, saving money. And so, somewhat with the same architecture, well, we can regret that the wall is a bit too easily accessible. In ten years, I've asked the contracted proxies to point to my Safe v2, which allows for updating and improving it. They also said they had no issues with functions on their Bastareaud and the contracted masters, so that reassures us in case of an accident. And so, other services and possible extensions.

We can specify whitelisted contracts and/or whitelisted addresses in our wallet, and where we can send without needing to use multi-site functionality. So just one person can send. That's interesting. They've created a multi-scene library for BAT transactions; that's very interesting. In these times when scalability isn't yet a reality and the blockchain is overloaded, and new services are emerging, including potentially fund recovery services—I didn't quite grasp all the technical details—but since they still control the master contract, there would be the possibility of filing a claim, and after three months, they would verify and release the funds.

So it's not about stealing; it's about if you've lost the keys to the multi-signature, a history and notifications of transactions on applications, and the ability to sign messages in multi-signature mode, if there's gossip. So it's very interesting for projects that will end up manipulating a lot of land. Last topic, very quickly, is chimpanzee, which is very much at the heart of all the topics today. It might not be the most exciting for everyone, but compliance, so everything related to regulation and legal aspects. So, Simon, a little bit about the euro, from there this summer in France, variable, so a little bit everywhere, and who is also a lawyer, so a jack-of-all-trades, explained to us in a very interesting top his vision of legal risks in the Blockchain applications, so it's very complex, they want to move quite fast, so there are more and more of them.

Why? Because institutions are looking more and more closely, especially with the bubble. So the SEC in the United States, regulators in all countries, especially with the bubble and the fact that 99% of projects are scams. So he presented us with a risk scale. If you want to think about your own project, if your APW EHPAD (French acronym for "Assisted Living Facility for the Elderly") exchange of securities, for example, only involves Times New Roman certification—yes, this document existed on such and such a date—there isn't a huge risk.

You should still consult a lawyer, but not too much. If you start doing token exchange against value, it becomes a little more complicated if you do a fairly high one. If you want to create a deco, then it's going to be very complex. You really need to get advice. And the financial stage, for him, is the absolute level of the queues.

We want to make derivatives, to replace certain mechanisms of the stock markets, etc. There we're going to get into the regulations of stocks and all these types of products. It's the most complex. List of things not to do, projects not to Not following them is simply collecting too much money; they have money without doing anything. They are respected here, and so New York remains, therefore, without identifying the people who invest, without having legal structures for their company, without paying their taxes, so not following the projects, for the people too, I suppose, not deceiving people because well, if we deceive them, they will be the first to file a complaint, and you will see the authorities rather than what you had planned.

It seems normal, but when we see the projects, we realize that there weren't many who were present, a stock, and so the conclusion was to ask a lot of advice from people who have already had their projects, other legal values, etc., from lawyers. We asked several because they each have their own vision and almost adopted the most pessimistic vision to be sure to cover all the risks. Last point, last point on compliance, see a presentation by Xavier Lavayssière on the regulatory frameworks for blockchain payments. He explained to us how to identify Respecting regulations means understanding where they come from, because they often stem from a different historical context.

Therefore, it's also important to be proactive, to lobby for their adaptation, because there's always room for improvement. This explains the need for global initiatives, but it was necessary to consider specific regional contexts. regional, so that's what we are in the United States, Canada, and Europe, and the objectives of payment regulation were to guarantee payments. We needed to be able to guarantee our payments, protect user data, and prevent illicit activities. That's easy to ask regulators for, but harder to do.

Promoting an open and fair market is n't the case for some here and now, for example, those that don't open up, like toilets at the beginning. Then he compared the regulatory frameworks of different countries. And lastly, I'm not going to attempt to pronounce Roth Kool Shen, which means robin in German, I think, hence the robin logo. And the risk of limpets rises, which is known for Hayden, who made this open- source tool to calculate taxes. There are already tools like that on the internet, but it's the same thing: giving you all your transaction data and everything else.

This party is n't in the spirit of blockchain. He did something to... Open source that can be downloaded and used locally, so it's better, it's more in line with the spirit of calculating taxes. To conclude, what should we remember? I put four little dots, glass bridges, I put more than bad orange dots because we have to be optimistic.

It's about scalability, and it's underway, it's coming. We see all the projects because they're blocked sometimes, they simply can't deploy on the platform. So, it's Pascale Hebel, they're working on their own solutions, they're implementing their own channel mode, their close associates at Channel, they're working together, and well, everything is moving forward, whether it's on-site, my sweat, the harding, things are progressing, so little by little, from CRM solutions to complex solutions, it's coming, and scalability, so we're less pessimistic than before. We see that the network effect and the developer community is immense. For summer, we're 130 presentations, left some presenters that we didn't like, couldn't participate, others who are simply made of lighting.

So, with so many projects, we see that for each user case, there are three projects tackling it, and for each problem, three projects working on its infrastructure or something else. This is encouraging; we think that all of this will lead to something more and more. We see interfaces and synergy in all the projects, so all of this is accelerating. All the projects communicate with each other, use stablecodes from other projects, and leverage exchanges to help each other and other projects. Each time, they gain value by using the solutions of others, so the ecosystem is forming and the added value is increasing.

However, across all DAPs—and this was the conclusion of all the presentations— they are having a lot of trouble improving the user experience. Nothing is yet as user-friendly as many centralized equivalents. MetaMask needs fixing, but it's still very difficult. Few of you remember your grandmother using MetaMask, so there's a lot to do, whether it's in terms of design or user experience. We need the building blocks so that people can better use all these projects, YouPorn in particular, one for The identification: if you register for the 7th and get the presentation, you'll have all these useful links.

It's full of reports from lots of people, all first attempts, the most interesting ones in French. A little tip: in Toulouse, they did a super interesting job and summarized everything. You have summaries, feedback from Simon, summaries in English, lots of projects that were present gave their own reports on what interested them, so it's interesting. Go check it out if you want to know more about the subject. Even more reports, and at the very bottom, links to YouTube.

Everything was live streamed, so you have either Edith's, the FCC website, or the four YouTube channels that were created, and you have all the streams of the projects we talked about. What did we miss? A lot! There are even people who are here, I see Nicolas from Ledger. We didn't talk about his project, it was too complex for me.

It's for the 7th. Thanks, of course, to Talent for hosting this meetup. The conference sponsors are the supporters of the FCC, so the foundation was there, and the CNAM, which hosted A7, is the most important, along with the volunteers and the community. So, Jérôme de la Scène presents the set; I called them the mastermind because I feel like he organized everything himself. This conference was really the central point; he was everywhere, he organized everything.

He's really the one who deserves the most thanks, after all the volunteers— more than 50 of them—who had his red caps from his Pokémon purchases. I displayed some of them. So, Alexandre, Etienne, Vincent, Scott, who were particularly helped with all this organization, and many people from the whole community. There are people from projects that we had printed, FCC t-shirts at A7. Everyone helped.

But here you have a photo in the room where people are eating, taken by a drone from the Flying Carpets project, which has another very interesting project that you can go see. I'm finished, thank you. It's a bit late, but if you have any of your own... Anything else to add or questions? We can have a short session with everyone who participated in this feedback session.

[Applause]
