 Hello Thank you guys to coming. Well, I am Fernando Marino. I am blockchain product manager and self-serve identity product manager at CEPICLD I will tell you a little bit about CEPICLD. CEPICLD is an independent and a private research research research center and development center in Brazil We have almost 1,000 employees nowadays and we act in markets like telco. Actually, we came from telco. We have 36 years old Energy industry defense financial agribusiness and technology and services providers We are also a Brazilian government partner Okay, that's our site in Campinas. Campinas is a city nearby from Sao Paulo Well, I'm here to talk nowadays about the RBB RBB. It's the Brazilian blockchain network. It's an initiative from the The development branch of Brazil, BNDS to create a public infrastructure in Brazil to use it for the public sector Okay First thoughts about the RBB first of all governance We're talking about to create agreements for the constructions and operations of the network with the common standards To there's members In a public and private partnership second network deployment of a common secure and Interoperable technological infrastructure of blockchain for the public sector Infrastructure one that's interoperates for example with the lock chain lock chain is the Latin and America Caribbean blockchain That we have in the South of America and Caribbean government services governments big tax and the start-ups develop applications of Public interesting what it is means it means that these blockchains is related to the Applications and the smart contacts for the public sector and the public interesting you're talking a little bit more about that and The foundation of that is the union between the legislative executive judiciary federal government state state government and the municipal governments Together with the private sector We have We have inspired this Action with another public permission at the network that they have for example Alaska in Spain EBSI in the Europe lock chain in the South of America in Caribbean and actually so bring so bring was The base of the governance model that you are developing Brazil. Okay or Purpose with RBB first of all innovation in the public interest team, okay innovation in the public sector Bring blockchain for the public sector of Brazil. It's very important for we You know try this new technology and try the services that we can offer for our president citizens trust Well, you know nowadays in Brazil have a lack of trust and nothing not even in Brazil actually but In the world as a whole but especially Brazil we are talking about a lack of trust trust in terms of government trust of How this bank it's used the National Brazilian Development Bank How it's being used to you know support Initiatives and offer the product the public in the private sector in Brazil that's the mission of this bank It's a public bank actually so The idea of RBB is and anybody can check the RBB and anybody can audit the blockchain of RBB and verify if the resources in these banks is used in the property manner or not or Why are you looking for we're looking far to first of all first innovation in the use of DLT technology for public interest applications with particular emphasis on Enabling the trust needed for antifraud and broad transfer AC measures Actually, it's it's aligned with our Account court in Brazil the TCU TCU is that card kind of the court of account in Brazil that check the Brazilian account and something like that Because the TCU has a decision in 2020 about regarding the pro-transparency and the antifraud Actors in Brazil, okay the decree 10,032 on April or in 2020 house in its eight goal the future future it talks about the future of the public services and emerging technologies and we have Initiatives to develop at six research development and innovation projects with the partners from the federal government higher education situation private sector and third sector We have also to make at least nine data sets available through a blockchain solutions in the federal public administration by 2022 this year So deploy their Experimentation lab with emerging technologies That's the resolution You are working with the RBB network right now and That's the infrastructure of RBB. We have the RBB lab where we are trying applications and solutions Using the this infrastructure here. You are talking a little bit more about this infrastructure in the technical terms We have in the federal Governments, we have the PNDS the bank that it took a data prep data prep. It's a company to A lot of data from citizens and companies several several is a kind of Public company for technology Technology for formation Brazil the state executive Prodengie and protest Prodengie process is also technology companies from the states the states of Minas Gerais in Brazil R&D and we are here R&D R&D is the network of universities in Brazil as a network for the universities to share researches and to get connected with each other to create infrastructures and Share labs and technologies something like that. So if you could see and the university and the Catholic University in Rio de Janeiro International connections we have a connected with the bid-lab the black chain And the federal legislative the TCU the court of cults, Brazil Okay, applications now which kind of Applications of public interest in we are talking about here Well, we have a lot of interest in application that you can use RBB actually for example Diploma issues. That's a problem that I used that we have in everywhere publicly citation To go post transparency to people to auditor the citations of the Brazilian government Tokens and publicly spending tracking. That's a very very interesting case Actually the BNDS is started with this application here. They create the BNDS token so when BNDS was Financing was Giving sourcing for our organizations public are not It gave these sources using tokens and then the organization has to spend the talking with the you know The companies that they are buying services or materials and then this companies exchange those tokens with the Brazilian currency rail. So doing that you can track Where the money is coming and What the money is using for? Notarization and digital signature for organizations at this time This application the RBB is not looking for to create a solution for Seasons identity. Okay, so it's not being used to identify It's using today for organizations and to Create services for the organization to the public sector But it's a public supervision at network. That's important to say which means that everyone Anybody can synchronize the ledger and object it and verify it Okay In the technical stuff what we are using here is in hybrid BESA permissioned version of it here. They know that You know, it's Mantended by a pleasure Then the nodes the nodes of the hybrid BESA interpret the ethereal virtual machine in the level code The course of our reason that you are using it's the proof of authority. Okay Now we are supporting all the three percent of imposters in our network No mining. I mean, we don't have them We don't have the mining in our network. What do you mean that? And tokens actually are optional. So we're not using at this time power consumption equivalent to normal servers That's a good thing. It's kind of beautiful superior to public ethereal But it is still limited nowadays and instant if in finality Support this network nowadays supports private transactions and maintain but we are not using it at first and to Deploy the network. You are using the script Based on lack chain. Okay. So we are very aligned with the lack chain with the lack chain in this network Lack chain is advancing in supplementary implementations for the network. So, you know, I Will tell you a bit about what CPQG is researching In the RBB and you see that you are actually are looking what lack changes is doing in its own network Well, uh, technical as our technical solution space and elections as I've told we have the boot nodes They are responsible for connecting new nodes The organizations responsible for the node must Electrically sign the terms of use for the network Also, we have the validator nodes. They are responsible to connect the new nodes The args responsible for the node must enter inside. This is a term this term here It's a kind of governance term But we are not counting it as a governance term for political and bureaucracy regions. We are calling it as a Technical agreement among the TCU and the BNDS and the participating we are signing This term as well But in this terms are describing the base of the principles of governance of this network Okay, the right notes the right notes this one here. They Sign in and sensor transactions to the ledger and observe her notes They can only read the information Register as on the network and they can be used by the citizens and organizations to all get to this network as well Well, we have a liability in the right regular notes and it's Scribes in this terms because you know They are writing in the blockchain the ledger so there's a little bit against what they are doing in this network Okay This then agreement that I told you the TCA technology cooperation agreement There is no transfer of funds between BNDS and TCU They are not involving money other ones are joining us at the patrons The main parts in this TCA this agreement in the BNDS and TCU they have rights to a vessel Associated participants in the consensus with the validators and votes They are as the pic of the arm is they have the right to vote in the governance Partners is a cute use the case. So they have the writers They are entitled to a voice in the governance in the future writers will not enter in the settlement I mean in the future writers It will not be necessary for them to sign the technical agreement TCA It's leans as a possible because the idea here is not to create the final governance model because we're learning with the public sector So it's lean as possible Most decision are in governance and are included in the regulations and the governance and regulations of the network are Provided for the TCA document Okay Here, I think it's a slide about challenges that we have first of all financial sustainability I mean a Few organizations as you saw is running these nodes here. So how they are being remunerated How can how they are it would be remunerated with the public sector? It's a leader We are not sure about how we will sustain those network in the long term. We are trying and Creating sites how to do that the long-term Lack chain writes by network sorry for example in the Lack chain writers when they buy a network access, right? Lack chain operates the network and Lack chain is remunerated for these payments Validators also are paid. So we have a business model for validators here We don't have it nowadays in our baby. You are studying how to incentivize like the interest to use to Validating the letter RBB Reducing these arrangements is a legal innovation that can delay the project and make it unfavorable What it means? It means if you we started to discuss in the regiment How to we will do the financial sustainability of the RBB we can Not get an arrangement with the government. Okay, so because of that we're not discussing it initially Participants can individually provide the final services having their own writers. So for example, so people do you Build a solution using RBB a solution that is you know after public interest in Also everything that I told you before then we can Provide these services for the organizations and receive for that Or access via other writers who can use it another writers for example Bucking you bucket you the university the university. They don't have writers. They can use it for example the right of reciprocality Join activities for operation and the volutions of the network. We will have to take a place in collaboratively IDB is open to possible arrangements that make possible a scenario more similar like Chen in the middle term The BNDS is open Okay, next steps network starts with a pilot in 2022 Tc participants only use case was used up nowadays on the participants or on the participants can run use cases R&D is Developing a digital diploma use case developed for Mac Mac. It's the Brazilian education ministry And the book you is Serves to signatures or digital signatures organizations called the subscriber yarn Typical G is studying the JG trust register based on the lock chain JG register SAA for pilots network and data security with a high level of trust Next step looking for full prediction new use cases for one notice he participants I mean another participants that like to use the RBV You are building a new kind of a term of use. It's a similar instrument, but it's It's easier to sign and to get in the network Provision services provision of the services by participants to know participants. I mean The participants of the TCA can provision services for another Companies looking for a typical production as a lead Okay, I think I was Fested hearing my presentation cause we got delayed regarding the Issue on my monitors and I have a minute for a few questions
