Kate Ugo, you're now live. Feel free to kick it off. Yeah, let's go. Everyone, let me introduce our speaker Eugene. Eugene Asif is a CTO and co-founder of Time Stack. He has a strong roots in engineering, cybersecurity and research with more than 10 years of experience in leading top R&D teams on a global scale. Eugene is a passionate about the driving innovation and building highly sophisticated products and technologies in multi-stakeholder environments. And he will present us to us Hyperledger Fabric on a Time Stack in his presentation, Next Generation Hyperledger Fabric Managed Services. It's a pleasure to have you here. Eugene, please begin your presentation. Likewise. Thanks, Igor, for a very kind intro. Hi, everyone. I assume that you joined us from different parts of the world. This is great. I'm currently based in Singapore, where Time Stack is cut ported. Our team is pretty global, and our customers are also quite global, but we are in this red dot, so live streaming from Southeast Asia right now. Let me share my screen and launch the deck. Yeah, so as Igor mentioned, I'm a founder and CEO of a company called Chainstack. We are building managed services for blockchain for the last three years. We focus on the protocols that are either being adopted already by the development community, or we are focusing on some new protocols that are on the forefront of innovation in the blockchain space, and that we think are gonna be the next big thing in the blockchain space. So one of the protocols that we've been supporting very early on is Hyperledger Fabric. So we're big fans of Hyperledger Foundation, of Hyperledger communities, and Hyperledger Fabric has been clearly one of the biggest protocols that we see people building in the enterprise blockchain space. So we've built our first version of managed services on top of Hyperledger Fabric version two, which introduced a lot of improvements versus version one, and I think we were the first managed service provider who supported version two at that time, which was a bit more than a year ago. So today, apart from just talking a little bit about what our managed blockchain services are, how they work, what are the benefits of using a blockchain managed services versus, let's say, building your own team for operations and developing the blockchain infrastructure solutions, I will also share a short demo of the platform because I love live demos. Our platform is quite robust at this stage already so that I'm very comfortable showing live demos, and I'm doing this all the time on all the events and all the webinars. I will also talk a little bit about the enterprise aspects of our solution, like why big players in the market, in the blockchain space are using Chainstack, what kind of enterprise features we provide on top of the easy to use UIs and APIs to manage and operate and orchestrate your blockchain networks. And we'll be obviously happy to answer any of your questions and dig into more details into how to build the next generation managed blockchain services solution. So a couple of words about Chainstack, as I mentioned, we're headquartered in Singapore. We've been mentioned a couple of times in garden reports about enterprise blockchain as one of the leading managed blockchain services. We have a bunch of patents around orchestration of complex blockchain networks, managing distributed ledgers as part of the solution that we build. And we also have pretty diverse team, which as I mentioned, is distributed currently in a few countries around the globe. Among our customers, we have names like Deloitte, PwC, Fujitsu, Kronis that have been using Chainstack for not only proof of concepts, but also for pre-production and production environments in multiple clouds, using multiple protocols and running everything pretty smoothly with the automation that we provide and also with professional services that we provide on top of the platform that allows more sophisticated customers to customize the platform for their needs. For instance, to host it in multi-cloud or even on premises environment that I will cover a little bit later. So what Chainstack provides in a nutshell is a way to start your blockchain projects very quickly so you can deploy a new blockchain network in 10 minutes, including the time to register on console.chainstack.com. You can use multiple protocols that we support. So they will support around, I think, eight protocols already, both public blockchains like Ethereum and Polygon and Bitcoin and others, as well as enterprise blockchain protocols, the leading one being High-Pledge Fabric but also with Porta and Quorum as part of our solution so that basically you can really quickly experiment with all these protocols, try to build on top of them and then see what works, what doesn't work. Again, some of our companies that I mentioned that we have as customers, they use multiple protocols for different kind of projects in different verticals. So this platform is pretty handy for them to operate multiple networks or nodes from the same environment in different hosting providers as well. So we support today in production three cloud providers, Amazon, Azure and Google Cloud. We support custom deployment in your private Amazon account also out of the box, it's completely automated and we also support different on-prem environments as well as part of our enterprise setup. I think someone had a question, actually I don't mind if we do questions in real time. No, okay, then I will continue. So basically the platform that we built allows us to start really quickly to try different things really quickly then deploy in very different heterogeneous setups and also then scale up because for us, we build the platform in a way that it doesn't matter, you deploy one node or 15 nodes, it's exactly the same process, everything is completely automated. So we don't really care like how many nodes we need to run because everything is being out of scale, everything is being operated not by humans. So in this case, it's really easy to scale up, add new members to your network and to operate in production as well. So having said that, this is only the infrastructure layer that I briefly described, which is not the only thing that we provide. So we also allow more or less full stack whenever you want to build an enterprise blockchain solution with regards to the distributed ledger technology. So we currently don't provide like off chain storage ourselves or we don't provide like something that is not directly related to the actual DLT. For this we have partners and tools and services in the marketplace, which is on the application tier that you see on the top. There we also provide different services on top of the ledger itself, for instance, for Quora, let's say, we support complete suite of Quora app management, which is not available out of the box with the Quora as protocol itself. So we allow you to deploy applications from the console using our UI. You can do the same thing using the API. So some of our most advanced customers build like CI, CD pipelines, we'd like spinning up the new network and then deploying the application on top of this network and then a shutting down this network and so on and so forth. So quite sophisticated pipelines you can build on top of our APIs. And what's also important is the mid tier which we call governance tier where we basically allow you to manage your members in the consortium really effectively by just like inviting them via email and also managing the identities for all participants in the network because we have a separate component called Vault where each member can manage their own identities for a given network and do it in a secure fashion. So the infrastructure tier which I briefly touched the advantages of, you can basically choose how to operate, right? So the easiest way that I will also demo today is to do everything in the cloud. Everything is fully managed by Chainstack. You don't need to run anything on your servers, anything on your laptop, you can just basically run the entire blockchain network in the cloud and also you can use the control panel that we provide, which is also managed and operated by us. Everything is absolutely automated including maintenance installation of the tools on it and you just pay for what you use. So basically you can use a network for a week and you pay for a week, you can use a network for a day and you can pay for a day. So the granularity of our billing is per hour which is very useful for those who wanna try out different things, they wanna move fast and they don't wanna overpay, they don't wanna overcome it to a certain usage for months or years. So we want to be really friendly to the developers. So we don't want to have this burden of agreeing on a contract, et cetera. So you can start building, like again, as I mentioned, you can deploy a network in 10 minutes right away. So then we have most sophisticated options for the deployment of nodes and networks and the control panel itself that we provide with API and the UI. Let's say the hybrid option which has been pretty popular among small, medium-sized consortiums. So basically you choose what to operate yourself. For instance, you want to run the nodes in your own cloud to have complete ownership of data, of the ledger itself, of the keys, et cetera. So you can basically choose to run the nodes of your organization in your own cloud. Let's say you wanna do it in your own Amazon account. It's easy to do. Again, Amazon is completely integrated. For instance, we also can do custom integrations with Azure, GCP or any like bare metal Kubernetes. So as far as the Kubernetes is supported, we can do hybrid deployment, which means that the console we operate so that you don't need to care about it and you basically operate just your core infrastructure which is basically compute and storage and we deploy everything on top of it in an automated fashion. For large and sophisticated and customers who need to conform with certain strict regulation, we also offer a self-hosted option, whereas you host the entire platform, including the orchestration components, including the nodes, as well as the control panel itself. So it's basically a self-hosted solution that we provide for those who want 100% of control and 100% of ownership of everything that is related to the DLT layer of their solutions. So these are a couple of examples of the real deployments that we have. So this is hybrid deployment basically. You have the resource management, the control panel, which is hosted by Chainstack. You have different cloud providers that are integrated into Chainstack out of the box, which you can use for node deployment and you also can connect your own cluster and deploy nodes there. Which is pretty cool. On the demo, I will show you how I just spin up a network in basically like five minutes of HyperLedge Fabric in three different clouds and three different regions and it works like out of the box, like magic. This is an example of self-hosted deployment, whereas you have a control panel hosted by the bank and the bank also has two clusters for node deployment, one in Singapore, one in the UK and they are both plugged into the control panel so that these two clusters can be used as a target for node deployment. So a little bit about the governance tier. Basically the idea is that you can invite as many participants in the network as you want. As I said, it's basically a piece of cake just sending an invitation to an organization administrator via email and then these members of the project. So you can basically have multiple projects on the platform as well as part of your organization and you can invite as many members in each project as you want, which allows you to build pretty interesting solutions on top of basically one platform. You can run different proof of concepts with different organizations within the same account and only those who need access, they will have access to your project. One project can be on supply chain and you have a project for that. One project can be for tokenization on different protocols. Third project can be the document exchange on high pledge fabric and it can be like a private project of one of your departments, let's say, of a bank, right? You can also have multiple networks in the same project, one for production, one for staging. So managing of entities within the network, like all the users or the members, it's very easy and streamlined on the platform. So last but not least, the application tier, you can use multiple partner solutions that we have. So we have partners like Diglessa that provides standardized demo language on top of multiple blockchains including high pledge fabric and Quora. We have like monitoring solutions, explorers. For instance, we have Web Street Labs as our partner who provide pretty sophisticated explorers solutions for different blockchain networks. And we also provide our own solutions in the marketplace like load balancing solution that we offer for public blockchains which is very popular for those who are building like high scale applications on top of public blockchains, for instance. So a couple of words about high pledge fabric support on Chainstack, currently we're on version 2.2. As I mentioned, everything that we do is based on Kubernetes. So all the workloads are containerized. They're segregated from each other so they don't have any access to each other's ledgers, to each other's chain codes, et cetera. To simplify the kickstart on the platform we have one initial channel whenever you create a network that all the member organizations can join and will join by default. Now we have one raft order included per network by default which is also free of charge which is also pretty cool because we know that some other managed blockchain service providers they charge separately for each component they charge separately for Kubernetes as a hosting. So we charge basically only for peer usage and nothing else. So you basically just pay for peer nodes, compute and storage and that's all. Of course in most sophisticated setups when people want like say multiple orders or multiple components that are not provided out of the box it's more like on demand setup and the pricing is discussed separately but out of the box we just charge for peer compute and order and also Hyperledge Explorer that we deploy per each member organization in the network we provide free of charge and you can use it as much as you want. So now let's show a little demo of a platform that we've been building. Let me open the right browser tab for this. So here is how change tag looks like. I'm in my dashboard. I see all my projects here as I see multiple tabs here. I can create a new projects. I can like choose the type of the project as I mentioned we support public blockchain as well as consortium blockchains. So here for Hyperledge fabric you need to choose consortium and just spin up a project that will be created in a second and you can use it to host your own network. So I pre-created a project in advance it's called Next Generation Credentials platform where government agencies and organizations can collaborate on education and training data. Here as I mentioned you can have members in your project. So currently I have a couple I invited MIT using my personal email and I have change tag as my primary organization. So currently I have a small consortium of two members basically that can collaborate and then create notes and then transact on this network. Creating a network as I mentioned is a piece of cake. So let's say we want to create a development network. We basically just select the protocol. So we support Hyperledge fabric raft. We have useful helpers everywhere to explain things that are going on in the platform. For instance, here you can read more about raft is if this word is not familiar to you like what's raft. We support different identity issues. On this plan I have Cryptogen as a basic one we'll support FabricCA as well. Hosting as I mentioned, you can use the change tag hosted nodes or you can also use your own cloud. For this you need to add the integration with your Kubernetes cluster in the integration section. So here you can choose between different clouds whether it's again Amazon Azure or Google Cloud we support different regions. And then basically click next and the network will be deployed with one peer node, two service nodes which is basically a raft order and explore. So that's exactly what I've done before just half an hour before the event. I have a production network running here. I have three nodes, two are operated by me by my organization which is called change tag and the third one is operated by my collaborator which I named MIT in this case. And as you see there are three peer nodes that are hosted in three different clouds in three different regions which is pretty cool and they can transact with each other like that. We also have service nodes here. We can see explore order. We can see the details, how to connect to the order. We can expert all the necessary credentials to connect to the order like TLS certificates and so on. We can also open up the explorer which again as I mentioned we deployed per each member organization to maintain privacy of the Hyperledge Explorer database. And well, it's pretty much vanilla Hyperledge Explorer that you if you're familiar with there's nothing new here. It's just configured automatically. All the members are added in the network automatically. So you will see them immediately. You will see all the chain codes deployed and so on and so forth. So since this is a pretty new network you see just a few blocks and transactions which are more or less about adding new organization into the network, right? So what you can do with this node for instance, I will go to one of my nodes and I can see basically the RPC endpoint. I can expert again all the credentials. I can quickly read up the docs like what do I do with this node? How to connect? And we have pretty sophisticated documentation on the interaction tools with each of the nodes like, okay, how to connect to your peer. We explain everything, all the steps like one by one you can just go through it like a tutorial or rather you can just go to a tutorial section and like choose High Pledge Fabric and basically go through our pretty popular University basic income tutorial which we wrote a blog on top of with the web app included and we used it in multiple boot camps. So it's quite, and also I know the digital asset they basically rebuild this chain code and build it on top of Daml which is also pretty cool. So you can also use the tutorial section to learn more about how to build on each of the protocols that we support. You can also see node logs or of course to understand what's going on with your peer node. You can also see the chain code server logs to understand what's going on with your chain code once you install it. So it's quite, it's quite complete in the sense that you can observe all the things going on on your network from the perspective of your organization which is important because let's say here's my collaborator called MIT and whenever I go to the peer I obviously cannot see the RPC employment for this peer because I'm not from this organization. So what I can see is just peer name so that I can collaborate and I can transact with this particular peer, right? We can also see the network details which contains necessary information like okay, what's my channel ID? What's my membership details on this network like organization name, MSPID and so on. I can also drill down into admin identity which is in the vault section and I can see the details of my identity here like what's the X500 name of this identity. I can see the issuers. So this is what you can do here as well. What is also very convenient you can export connection profile that you can later use in many SDKs that are built for Hyperledge Fabric like Node.js SDK or you can use it as part of amazing IBM blockchain VS code extension that we use a lot in all of our projects and it's very convenient to kickstart your development on top of Hyperledge Fabric. I think it's a great tool and we have complete integration with it. So in our documentation we can read up how to plug in Chainstack network into the VS code extension. So I think that's pretty much it for the demo. Let me get back to slides and taking from there. Yeah, I wanna spend maybe like five minutes about Chainstack Enterprise offerings because I'm sure many of you are interested in, okay, so you have this simple platform what about security, what about privacy, what about a dense management and how you operate things like how we know that the platform is robust, how we know that it's secure. So I'd like to cover a little on that and explain our best practices and how we maintain everything that we do. So we have all the trails enabled on all our systems. We do regular backups and disaster recovery tests for the critical parts of the networks. So for instance, we do backups of the ledger itself, of the database, like order database as well and so on and so forth. So we basically backup and do disaster recovery trials for all the critical components of the network on Chainstack Enterprise plan. So we also enable a role-based access control for all our employees of course and we do storage encryption by default which is conveniently available in all the cloud providers out of the box and we also do it on premise for larger customers. We do all security best practices like vulnerability assessment, patch management for the entire code base for our Docker containers and so on and so forth. We use TLS everywhere. So we cannot connect to our peer without providing TLS certificate because the security and encryption in transfer is also extremely important, especially when you do a distributed ledger technology solution. We also have two factor authentication of course for all our internal systems as well as for Chainstack console as well. So you can enable it in settings. Identity management we have a very careful approach for because in any decentralized solution that requires to use identity, it's the key. So if you lose your identity, if it's compromised then there is a problem all the time. So we want to make sure it's stored in the most secure fashion possible. So our Chainstack vault is basically this solution which is built on top of hash and core code and also storage solutions with encryption that are available in the public cloud providers and which are pretty sophisticated. We also allow you to use external KMS or even HSM for key storage on the press plan as well as an additional option. We have zero data touch points for on-premise deployments. So we basically don't know what's going on there because we just provided the software for hybrid deployment. It's also available basically as soon as the data is in your own cloud like the ledger database, all the compute that is happening on top of the nodes are basically hosted in your own environment and we have no access there which can be leveraged. So we just use it for orchestration. We use least privilege best practice everywhere for all the deployments. So we, for instance, if you integrate with your own Amazon EKS cluster, you will see that the roles we require for the private hosting deployment is minimal and only necessary. So we, for instance, we will obviously not ask you for like admin access into your AWS account which will be ridiculous, right? So as soon as we're using Kubernetes and Docker everywhere, each application process is isolated and the data is also isolated. So there's no way that applications can get access to each other and different nodes can get access to each other. For operations, we have pre-sufficcated dashboards built internally for monitoring and for alerting as well. As a user, again, out of the box in the platform you can use the activity log feature that allows you to read all the events that happened on your projects, on your networks, on your nodes and see the complete audit log. You can also see logs of the node that I just demoed before. And for sophisticated and advanced customers will also provide solutions for on-premise operations with monitoring and alerting to enable the top grade reliability that we provide for our hosted solutions as well. Last but not least, we also provide professional services on top of the platform which are again, pretty popular among advanced customers in banking sector and those who are building large scale consortiums. Whenever the customization is required our professional services team is ready to help which includes basically just recommending where to start, like how to build on top of the protocols that we support, how to choose the right protocol, how to compare like, let's say, performance of fish protocol and so on and so forth, like how to onboard partners in an efficient fashion and also another services related to orchestration of your network or whether it's organizational orchestration or technological orchestration. So that's all about our next generation managed blockchain services that we've built. As I mentioned, we have brief sophisticated documentation for all the protocols, including hyperlatch fabric, of course. We have a lot of articles on our KB. So if you go to support.chainstack.com you will see a lot of questions that you might have and you will get answers there. You can start for free on Chainstack which is pretty cool. So currently we have 14 days free trial for the platform and as part of this event we also provide an offer for growth plan for one month completely for free. Growth plan allows you to deploy up to three peer nodes in your account and create as many projects as you want and you can also create like up to three networks. So it's a good plan to start exploring more in details what the services are available. Because developer plan allows you basically just to deploy one network with one node which is not that cool to see how nodes talk to each other and to build like a viable network, right? So for this purposes we offer the growth plan for all participants of this event here. I think we're right in time. So we have plenty of time for questions. I see there are some in the chat. So I think we can go and look at the questions, right? Okay, I see some questions let me take from the beginning. That's fabric support risk V platform. Actually we're trying to run a risk V based board but unable to do so. I assume it's a question more to hyper legend to change tech, change tech is built on top of traditional architectures. So nothing custom here that we provide at the moment. Does change tech provide a test net? As I mentioned, you can register for free on console.changetech.com and use the platform for free. So usage also is provided for free. So you can run a node for basically 14 days and play with it and go through all our tutorials and so on. How many best are available and most importantly for what type of business cases? Could you show an example for supply chain finance? Great question. Change tech is an infrastructure provider, right? So we don't provide at the moment any industry vertical APIs or use cases out of the box. These are usually built by our platforms, platform partners. So you can think about change tech as AWS of blockchains. So on AWS anybody can build any solution on top whether it's supply chain finance or a new, let's say, Neo banking startup or whatever, right? So you can build any type of solution on top of the infrastructure platform like AWS. Same applies to change tech. You can build anything on top of change there. Only imagination is the limit. But at the moment we don't provide any business case specific APIs or functionality. This is done by our partners that are building this on top of the platform. What version of Hi-Pledge Fabric is this Ryan? I think I covered this already. It's 2.2 and we tend to upgrade to the latest versions. We obviously do a lot of testing before we move the latest version to the production but we try to be on the latest versions as much as possible. Does change the plan to host framework specific webinars to call a startup project for some use cases? We've run a couple of very large boot camps before on Hi-Pledge Fabric and we used some projects like SMS like Universal Basic Income which is not really like very industry specific. So it's more like a tutorial kind of project but it's very real because on the largest boot camp that we ran like a half a year ago we had like a network of 40 nodes running within two hours. It was very massive. I think it was the biggest Hi-Pledge Fabric network built within two hours for sure but within such a short timeframe for sure as well. So we don't really have industry specific webinars or events at the moment. We do run those with our partner. So if you have any ideas or if any suggestions or maybe you even want to run a webinar with us and build on top of and have a showcase solution built on top of Chainstack we'll be very happy to hear from you. Please reach out to me or Alex who's also on this call and we will get it sorted. How do we differentiate your solution from other managed blockchain services like from the IBM Blockchain Service or from Azure Blockchain as a service? Azure Blockchain as a service is discontinued starting from September. So we don't have to differentiate ourselves anymore from Azure. Also Azure never supported Hi-Pledge Fabric and Quarta which are in our opinion top two blockchain protocols for enterprises. So there's not much to differentiate there. On the protocol analytics we also have annual report which is called Enterprise Blockchain Index. It's also pretty popular in the ecosystem. We have a fresh version this year that shows the growth of Hi-Pledge Fabric and Hi-Pledge as a community in particular. So feel free to go to Chainstack.com and find a copy of the report there. From IBM Blockchain Platform, I briefly touched this. We don't require any commitment. We provide free tier. We provide very affordable pricing for all our services. We don't have any hidden costs. Everything that you see on Chainstack.com slash pricing is what you get. So basically you just pay for the plan which is basically a membership cost every month and then you pay for peer node usage. That's all. No other costs, no charges for Kubernetes, no charges for traffic, nothing. And it's also very easy to use. So you can kickstart right away. You don't need to read a lot about Blockchain, about Hi-Pledge Fabric. Of course you need to be aware of distributed solutions but you can generally speaking any developer who is familiar with Linux console a little bit and who used Node.js, you can start building on Hi-Pledge Fabric right away with Chainstack. So very low barrier to entry versus any other players as well. Can we build and deploy solutions or marketplace for consumption by others? Awesome question. You can and you need to do this. The marketplace is currently more or less like a boutique marketplace so it doesn't allow anybody to bring in their solutions at scale but obviously we are happy to onboard partners who have interesting and value-added solutions on top of the platform and we will be happy to integrate with them. So yeah, clearly the answer is yes. It's not a mass market kind of marketplace when everybody can just go and publish their own solutions. So you need to get in touch with us and we will evaluate your solution but we will be happy to hear from you guys. By when would you move to Hi-Pledge Fabric 2.3? Is there any roadmap? Great question. As I mentioned, we try to maintain the latest version all the time. We have this in the backlog for our engineering team. I think it will be completed around Q3 this year. Questions from YouTube? Are all organizations required to host on with Chainstack in order to join a channel? Today, if you want to use the platform as is you would need to have an account on Chainstack and then you don't have to host all nodes on Chainstack because you can host your nodes in private hosting that we have integration with, right? On enterprise plan, frankly speaking, any configuration is available. As I showed, you can start from fully managed, fully hosted solution and go to completely on-premise deployment. We can also add or build a way to add members, not from Chainstack. On top of the network that is built there originally. But again, this is currently available only for enterprise subscribers. So for instance, I think the question is rather if I have a network running on Chainstack and then I want to host my peer on my laptop, can I connect my peer to this network running on Chainstack? Currently, there is no direct way to do this on the platform. However, again, we do this for enterprise subscribers at scale for different setups. What's the process to add new blockchains not supported yet? Awesome question. Basically, we evaluate all the blockchains all the time to some extent. So we analyze the ecosystems of enterprise blockchains of public blockchains and we try to basically support a protocol before it's getting too popular. So because when it's already too popular, it means that there are already people building, there are already tools. And we want to be one of the first platforms on all the emerging protocols to support the growing developer communities there. So again, there is no strict process to add new protocol. At the moment, it's currently being decided obviously by the team. Since we are a private organization, we have some crazy ideas to move to DAO at some point so that our community will decide which protocols Chainstack should support and so on and so forth. But this is a little bit far fetched from now, I think. But we have some serious thoughts about this because we think that the DAO model is very interesting and decentralized decision making is a great idea in general. I think that's all the questions. I think we still have some time so we'll be happy to get more. Yeah, thank you so much. So I have one question here. Can you hear me? Sure, sure. Yeah, go ahead. Yeah, can we host our own orderer for each organization in your platform right now? Yes, it's available only on Enterprise so you cannot do it out of the box like from the UI once you register on the growth plan but we support multiple orders. That's basically because we have the cluster raft deployed by default so adding new order is not very complicated. For instance, we don't use solo ordering service of course or we don't use single raft cluster. We have a clustered mode for orders so it's not complicated to add a new order but it's not the function of a platform that is available to everyone at the moment. Okay, thank you. Alex, there's a question for you. Do we expect to get some fallout communication on the growth here plans? Yes, we do. I will be emailing you guys with more information. If you would like also to email me directly I've posted my email address on the chat and it's just like a straight line to me and we can activate it right away. So it's alex.albano at chinestack.com and I will be posting it again so that everyone has access to it. Okay, thank you so much. Thank you, Ogin. It was a great presentation. Thank you so much. Please reach out to Alex to use China Stack for free and if you want to learn more about the Hyperledger and Hyperledger Fabric please sign up to our newsletter. I will also post the link in the chat. So I checked also YouTube if we don't have any other question. No, this presentation also will be, this recording will be available on YouTube so please also check our YouTube channel. Thank you, Ogin. Thank you for all part of this presentation. Fantastic questions. Thanks all and see you in Chase Tech. Thanks everyone.
