 Hello, everybody Marisa, Mauricio mentioned. My name is Diego Fernandez and the secretary of innovation of the city of Buenos Aires and I will show with you basically how we were dealing how we were planning with self sovereign ID approach and How do we got to the point that we are right now? So I'm gonna show with you quark ID, which is a self sovereign ID protocol that we promoted But let me start Thinking about how do we deal with identity in the analog world? Let's think for a second about our wallets In our wallets, we have a chunk of attestations of our identity Maybe we have a driver's license in my case. I have ID from two different countries here in Argentina. I have a credit card from Two different banks. I have a card from my health insurance company I have a card from my football soccer team river all of those institutions gave me at the stations that make my identity All of those institutions don't know that the other institution gave that credential to me Nevertheless, all of them agree on a set of given standards, which is quite basic It's the hate and the way on the width of the credentials and why is that? Because we have our own wallets. We have our wallets. I have a black wallet and maybe Each and every one of you chose a different color of wallet We choose a wallet that we want and we put the credentials in the wallet that we choose and How do the verification of this credential works in the analog world? And follows this triangle over here The most important part of this triangle is the line that says trust in the base of the triangle and why is that because Let's say for example that they want to say the city government issues a driver license on my behalf Stating that I am able of driving a car Then a policeman stops me and say hey show me a driver's license, please That when I showed my credential the policeman needs to trust the one-sided city government needs to know how the one-sided city government Makes credentials in order to be able of verifying that the credential is valid and it's not a forge But let's think of the last 30 years when internet took over and we became digital How do we deal with identity in the digital world? Well, we have a huge problem there why because we don't have yet a digital ID primitive And I'm really excited that I think that this is starting to change that we are starting to build a digital ID primitive but today and we are all familiar with this in order to ensure let's say a bank An insurance company or whatever in order to be sure that the other party is who we think we It is each company needed to make their own security frameworks their own security approach Hence we have tons of apps in our in our cell phones We have an app for the bank and that for the government of the national government and not for the local governments Up for the health companies up for the airlines Taking this into the analog perspective would be the same as Hey, sorry, I don't have a timer here I don't know. I don't have a timer. Sorry going back Comparing this to the analog to the analog model would be the same as if when the Buenos Aires City governments gives you a driver license The driver license came in a wallet that says Buenos Aires City government when visa case gives you a Credit card comes in a physical wallet that says visa and you will we would be carrying a back full of wallets It doesn't make sense in the analog world, but we do it in the digital world We have pages and pages of up in of apps in order to be enabled of interacting with any given organization What is the great? Advantage that the self-slover and digital ID model proposes as you see conceptually is quite the same Model of trust that we have in the analog world but it's much much better why because As you see in the base that trust line is not more solid line And why is that because a blockchain comes into place and we go into in deep into this in the next few slides this sure creates a digital identifier and writes that this is that identifier with its associated cryptographic materials needed to decode it in a public blockchain When the issuer means a verified credential to the wallet of any given holder the holder is first able of Accepting or rejecting the wallet and this is really important in this model Nobody can airdrop or give a credential to a user if the user doesn't accept the credential When the verify requests at this third proof of that credential This request is claims based not credential base. Let's say I have three dollars nineteen seventeen and fifteen years old Of course when I go to a bar and request to be or nobody asks for my ID because anybody assumes that I'm over 18 But does that's not the case of my daughter in today in the analogs world. We have a credential based The Authentification or verification so we give for example my daughter when she requests a beer in a bar She is forced to give all of her information all of the information contained for example her ID card to wait her Handing her a beer in this search over an ID model It's only claims base and you can give proof of certain aspects of your identity without needing to reveal All of the claims contained have given verified credentials. So for example, my daughter could just Send a proof to the waiter that she's over 18 not giving her name not giving her address not giving what any other characteristic of her persona and as that proof contains the digital identifier of the issuer The verifier doesn't need to trust her to make no integration whatsoever with the issuer Because the verifier is able of checking in the blockchain that the verify credential is valid and that They was signed and created with the private keys of the issuer. So what goes on chain and what goes off chain and this is Really really important. The only thing that goes on chain is that this is the identifiers and the associated Cryptographic needed to understand that this is the identifier. They are on your right hand side You can see what's the structure of a any given this to identify the quark ID model has Every verify credential every every personal data goes off chain Every personal data is stored in the user's personal device in the quark ID protocol we are using an open source wallet that open source wallet is non custodial and And everybody asked me in this point. Hey, what happens if I lose my wallet by my phone? Well, you have two choices if we were if you were saving up of storing your private keys and Backing up your confidential storage Then you will be able of recreating your digital identity wallet immediately if you didn't do that You're in the same situation that you are today in the analog world. You need to go Again to each and every institution or organization that gave you a perfect credential and request that credential again I'm gonna do a quick review of the four layers that the quark ID protocol has following the quark the trust over a p-foundation model in the level one is the blockchain level the Distributed ledger levels where we write Every this day identifiers so that is available to anyone in the world that wants to verify it In the later to we deal with a peer-to-peer communication with the Asian communications in this scenario we were thinking before When a waiter comes to my daughter and say hey are you 18 years old? He will establish a peer-to-peer communication with no agent in the middle whatsoever This is based on the did come protocol, which is an evolution of the hyper leisure areas the third level Relates to how do we deal with proofs claims and credentials? What is the way that we interact with those proofs claims and credentials? and the layer four is the ecosystem level is where we store where we sort of announce all of the issuers all of the entities available or Authorize in order to issue credentials one very interesting thing about the trust over a p-model is as each Layer of this technology stack has a governance stack as well I'm not going to go into the governance tagging by you to go into the trust over a p-model Trust over a p-foundation website because it's a really interesting approach So let's go in deep into quark ID How do how would how do we envision quark ID? We had of course the chance of saying hey, let's wear a government Let's go and do this government implementation Let's make the way outside ourselves over an ID protocol, but we're convinced that that's not the way to go Why? because we're convinced that The way that governments interacts today with society need to change we believe in open permissionless blockchains and we believe that Any god any protocol created by the government wouldn't be trusted Just let me ask you a question. Would you trust a protocol created by the government now? Okay, I wouldn't either so what we did is we called Argentina has a very big and very thriving community of developers of companies of projects Most of you for sure know open sepul in this central and sandbox Pull up with Patricia RSK IO laps I mean I can keep on mentioning we have a really strong really strong ethereum community in Buenos Aires So we called all of these guys and say hey, you know what? We're gonna pursue this goal Why don't you help us? Why don't you help us develop and this is and That call was pretty successful and we started building quark ID I wanted the definitions that we did one of the first definitions that we made is this Mustang this shouldn't be a government protocol. This should be a community protocol Do you have a white paper on the internet is an open source protocol? It follows the standards that I mentioned in here the center is identity foundation the w3c trust over every foundation and we decided to implement within the protocol compatibility with the open ID connect because of the huge possibilities that that in that implementation brings us and of course if we are Ambitioning the self sovereign ID model it as a way of identifying ourselves not in Buenos Aires Not in Argentina, but in planet Earth We need to be compatible with all of the implementations that are being developed around the world The most important of them all perhaps the ID union which is the self sovereign ID model that the ID union is proposing with the NGI lab Sovereign which is the perhaps the first self sovereign ID model which was developed an ion Which is an implementation developed by Microsoft over the citrate Modena protocol Work ID is also developed over core a citrate Modena protocol So how does quark ID works? Imagine quark ID as a Self sovereign ID layer. It's like a layer that goes on top of any given blockchain So the first we needed as I mentioned before in the layer one of the trust over every model we needed we need Distributed ledger blockchain the first blockchain in which we anchored the Quark ID product was Ethereum layer one. We made that that anchoring Not envisioning to use really if you must as a security layer because of the gas cost Which will make it impossible to mean for example, you know one million credentials But anchoring the protocol in layer in Ethereum layer one made it Extremely easy to anchor it in any EVM compatible blockchain The second thing that we did is we took the ion implementation that Microsoft made of the citrate Modena protocol Using Bitcoin layer one hence you can use quark ID anchored in Bitcoin layer one And then we started with the layer two world the first implementation that we made is polygon The second one that we made is RSK RSK is an EVM compatible blockchain which anchors itself in Bitcoin and the last one Was stock net as you can see the the vision in quark ID is This protocol needs to be chain agnostic and that is a for us is a crucial definition. We're planning on adding Different anchoring blockchains so that any ecosystem that decides to implement quark ID may choose Whichever security layer they wish we as the sort of Buenos Aires decided that the first implementation that the first anchoring Blockchain that we that we would use is stark net. Why did we chose stark net wall because they're Ck proof technology is pretty sound and it enables us to do a huge Scaling because we can do a quadratic scaling. We told scale transactions in stark net and then we scale transactions in quark ID hence We are able of using the self-sorbent ID protocol quark ID protocol With not even cents on the dollar for minting Hundreds of thousands of credentials that is extremely important for us took So as I mentioned before we developed this and we were able of achieving this with a strong set of partners Extremion which is a depth house located in Gibraltar stark work, which is a Blockchain that you probably all know based from Israel I of laps Which are the creators of RSK beyond always city excap it etc a Very important thing. What is the road map for quark ID in Buenos Aires city? We're rolling out the MVP in November this year We're launching the protocol in January 2023 and What is our adoption plan? We hope to Create 30 different Verified credentials that mean 30 different documents. Let's say birth certificate marriage certificate Driver's license to have a road map of 30 different verified credentials And we plan to mint between 300,000 some 500,000 this identifiers that mean this is our identities within 2023 just to give you an idea Buenos Aires is a free million sorry Free million city three million people city But actually we are seven million people community why because we have nearly between three and four million people that commute Every day to work in Buenos Aires. So we're going to start in 2023 Having between free hangar and five hundred and five hundred thousand sorry. I speak English the second language And We would like as well to have and we are looking forward to that three different private sector Organizations using this security framework to mean their credentials. This is very important Nobody needs to ask permission to any government to use this any given organization made mean their credentials without requesting permission from anyone and any Any community in the world can use this protocol for free because it's an open source protocol So quark idea natural first is an open standard self-serving ID protocol second is multi-chain Third is interoperable with most of the solutions tackling. This is the idea in the world fourth every private private data is off-chain Five it's it's gonna have autonomous governance. I'm gonna do a small point here today The governance is being made by this see ecosystem of partners, but in the protocol roadmap is Generating a DAO in the next 24 months so that the protocol is being able of getting governed by the Ecosystem of I mean communities partners or whatever use the protocol. This of course is a very hard and difficult thing to tackle We have all seen the problems with calling both in etc. And it's something that we're working quite hard on it six We're creating or quark idea is creating a growing public private ecosystem and Seventh and this is the most important point the government is a user We don't want users of the government We want to be users as a government that this is a change of paradigm which for us is quite important So last but not least why did we choose this path? What is the dilemma that we face? When we tackle digital ID Are we gonna prove positives? Where we're gonna prove negatives what I mean by this As all bound token is a negative proof is something that you can You can say no that you receive and that proves certain negative aspects of you I mean for example, you don't have credit You don't have credits outstanding credits. You don't have criminal records or whatever Proving positives is where I just described with in the perfect relations model Which is data that you have in and that you can Show or not according to your will in our view both things are necessary and both things will occur but Self-ownership and positive reputational systems come first We need to develop what I was mentioned before this Identity primitive that we don't yet have on top of that of that identity Negatives will unleash a great power Of course and and that great power would be immense for this in franchise community, which will be able of Requesting loans for example just using the reputation as a collateral But it has certain Potential negative things that we are we don't think that we are yet in a position to Sort of deal with just to give an example If I have post a negative reputation that I am for example a woman or that I am Attending a mosque in United States in United States that person will have 68% chance of not getting a job compared with a Christian woman I took this out of the podcast of Evan Macbillam and Vitalik but then which I strongly recommend you all to hear because it's It's really really interesting So thank you very much. I invite you all to get into the quark ID dot org Website download the white paper and we hope that in the next. I don't know. Let's say 30 days 60 days We will have the code available in GitHub and published in the quark ID website. Thank you very much Thank You Diego We have some time for Questions anyone have a questions? There there is one two questions. Yes three questions come on For who okay the first one can I made you in Spanish or in English? I think okay my friend And I am a Vladimir from Ecuador. I think the concept for a soulboat tokens and so self-sorring Identity will converge in that in some point. What do you think I complete the ring? I complete the ring. I think I think that soulboat tokens and verify credentials Are two different aspects of our of our identity? the positives the verify credentials are the things that I Mean that conform my identity The soulboat tokens rebuild certain certain socials interactions or resultant attestations that of course will unleash a huge potential The thing is that in our view? We need to start with the verified credentials model and then evolve into the reputational Aspects that the soulboat token proposes And then we will because those are all all of those are on chain and Once you write something in a blockchain It's really forever So we need to do first in our view with the verified credentials and they did this identity in a self-sorvorn ID model And then move to the soulboat tokens Proposal proposal next question there, please So great great talk. I really like it very much. Who helped you on building that strategy? Sorry helped you on building this strategy for this project and who helped you on the vendor selection Who have a watch sorry to find the right vendors like Polygon and the others who helped you to find the right protocols and partners well Actually, we did this with the with a set of partners that I mentioned before with the guys with it from Extremion from the gates with Iob elaps from the guys with the guys of our beyond With a lot of help and I want to mention this with a lot of help from the ethereum foundation from Maya from Steven from Skyler and How did we choose in which? Blockchains to anchor of course as I mentioned before we started with ethereum because it was a no-brainer and I was lacking after me. We were lacking enough of being able of chatting and Discussing with I mean and I would say every big player in the blockchain arena And they were more than willing and open to share the details of the protocol and to Offer support for us and I feel very proud about that At the end of the day we decided to anchor The city of Buenos Aires in start met because of the hope that they provided us and because we really believe in their technology And we think that's your knowledge proof technology unleashes a whole deal of implementations in a self-organized model which we want to take Next question here, and there is some hands there and there can you hear me? Yeah So thank you so much for your presentation and then as a Latin American I'm thinking about the user experience So I imagine my family or my friends using very valuable credentials for reputation or Any other use cases, but my question is what is your roadmap or user experience? Like if I lose my phone, are you thinking about other ways that I can recover my wallet? Are you thinking about and other ways to a store the very viable credentials because in Latin America? For example, what's up usage is huge But people sometimes don't have a lot of storage to store different apps, so it's better to just have what's up for them So I'm just wondering what are your thoughts and user experience in general for these use cases, okay? Just I cannot get who's speaking the police race you have. Oh here Well, it's a very good question I mean user experience when you're planning in millions of people implementations are the thing that you need to deal with I always like to say that We're giving you this possibility with this protocol first you can use we're starting with three different wallets the quark ID protocol wallet Excapit is building and which is a crypto wallet is building an implementation for the quark ID protocol and always city has a digital identity wallet that is also being made compatible with quark ID As I said before my talk you are able if you have the technical knowledge I mean if it's not taking that I mean if you go to settings and you explore your private keys So you store your seed phrase in whichever place you wish and you do a backup of your confidential storage And say you put it in your Google Drive or you take it out in a pender or whatever Then if you lose your phone nothing happens you take your private keys You recreate your wallet you take your confidential storage you sign it with your private keys And then you have your wallet you digital wallet Online online in your phone again Of course if you don't have that knowledge You will need to go again to each and every one of the means of the issuers of your credentials and request a reissue the same way That you when you lose a physical wallet today you need to recreate all of those documents in our view we're really focused on giving users the best experience whatsoever and start sort of a Sharing how users may back up and safeguard their own data In our view those I mean the share of people knowing how to back up the data will increase over time and We hope that in the next few years everybody will do it Each time I get this question asked I share a personal experience that I have I have I am 50 years old My mother something like 30 years ago say you know what son he was 60 something. I want to Learn to use the computer would you show me how so I say okay sit with me Grab your mouse and put it in the start bottom. It was a windows 95 So she took the mouth. She did like this in the screen. So, you know what matter now You need to get a you need to get some but I cannot teach you today my if she hears me She will come to that today my 83 year old mother Uses what's up does FaceTime sends mail Configures her own email. I mean 30 years past, but we're positive that people will get to understand web-free and We think that we have the power as a government of Onboarding a lot of people into web-free technologies and that is using the power for good in my humble perspective Thank you very much Diego and thank you all for your questions If you want to ask anything else He likes to talk a lot
