 Hello, I am Sretish from Ripple. I have recently passed out from National Institute of Technology Ripple and I'm currently working with Samsung Research Institute, Bangalore. So, current I'm working on the project implement cross-chain contract invocation using Service Meshway. So, in this project, I have used Hyperledger Fabric and Hyperledger EBM and Hyperledger Besu. So, my project description goes like this. So, basically, my project aim was to achieve a cross-chain contract interoperability between two or multiple networks. So, let's say we have a Hyperledger Fabric network as a primary network and Hyperledger Besu as a secondary network. So, to standardize these things and in a loosely coupled architecture we have implemented a Sidemesh library and a Vile service which is an event-driven service which is responsible for getting the events from Sidemesh library and simultaneously doing the transaction on other networks. So, in the Sidemesh library, I have used three functions which is prepare, confirm and query the global state which is kind of a two-phase locking mechanism in prepare and confirm functions. So, and the measure is responsible for like invoking the confirm in other networks and querying the global state just like that. So, here is a quick architecture of and a sequence diagram of my project and I don't know if it is visible or not but let's say we have a Hyperledger Fabric, Hyperledger Besu as a primary network and Hyperledger Fabric as a secondary network. So, it just, we have to register and verify some contracts, some Sidemesh libraries which is already deployed in those networks and the measure service is responsible for invoking the transactions on other networks. So, currently my mentor has already implemented the three Hyperledger Fabric networks and achieved a contract interoperability in the chain code. So, I have a project aim of converting this entire ecosystem in solidarity-based smart contracts so that it can support multiple EVM-based blockchains. So, in this project, I have used multiple libraries and framework just like the measure is, measure services built on Spring Framework and for solidarity-based smart contracts, I have used GANARCH for the primary work and for test networks and Interface Root for developing and testing the contracts and Java Web3 WebPers to generate the Web3 Java WebPers for solidarity and the Hyperledger Bureau EVM is running on top of Hyperledger Fabric which is used to deploy the solidarity-based smart contracts in Hyperledger Fabric. So, my project objectives involves first to understand the already built Hyperledger Fabric-based networks and to implement the Sidemesh library in the solidarity and for this library, I have to make a measure Sidemesh Relay which is responsible for invoking and subscribing to the events released by this library and simultaneously executing transactions on some other networks and to make a sample network by using all these libraries and relays. So, these are my project deliverables. It's the same. So, I have accomplished this Sidemesh library and measure service relay with some initial works in the design docs like adding some features or something which is missing in the initial design doc and the entire transaction life cycle is also like a little bit worked so that it can support the solidarity-based smart contracts. So, first I have run into the major challenge of running how to run solidarity-based smart contracts in on Hyperledger Fabric. So, Bureau EVM is the answer. So, I have to continuously use this Hyperledger chain code EVM and Fab3 interface to just building up the EVM on top of Hyperledger Fabric and deploying it, deploying my smart contracts on using the Fab3 in this Hyperledger Fabric and other network would be the Hyperledger Basu and Ganash and Hyperledger Basu is just like giving me the wallets and private keys so that I could interact with the network. So, like another challenge I have gone into like the initial go implementation of chain code is a little bit tough to understand. So, my mentor helped me a lot in this part like building but in the go what there is a kind of Hyperledger Fabric support is there for like integrating with the Spring framework in Java but for the solidarity-based smart contracts I have to generate the wrappers and all these things so that I could just execute one functions on the Spring but it was also a little bit like a little bit difficult part to just without the wrappers and running the functions and so and for the future works I would like to recommend that supporting as many as EVM-based smart contracts, EVM-based blockchains so that to achieve the interoperative between like multiple networks and like for this project I have used only two locks to maintain the states between the networks so it would be better if you could add more locks to the system and giving it a more like stable architecture and finally the service mesh architecture can be used in different contract-based blockchains so that to achieve a contract interoperative between them and here are some outputs and results so entire code has been pushed to this organization it has like separate repositories of relays and smart contracts and here is the design documentation which I followed for the transaction lifecycle documentation and here is my stability-based library and the sample implementation and for the inside scan I have learned a lot to like first of all I have built a library from scratch using in the Solidity so it would be a like I have to add the multiple support for different different type of use cases so it would be a good task for me it would be a and I have learned a lot about the open source development and trying the new things is a bit challenging for me but I would see and thank you and any questions thank you shri tesh I really appreciate your transparency and sharing some of the challenges that you encounter during the mentorship but I'm also just happy to see all the learnings that you gained through this experience so as an overall it's a positive experience I really appreciate your contribution and learning about all these different technologies I don't see all mentors on Zoom it's parallel too late in our time zone I know both of them are from China so they're not here but we will be distributing the final evaluation to the mentors this week so I'll gather feedback from them and but also feel feel free to reach out to them as well for any remaining tasks that you need to complete that you need to complete okay sure sure great thank you yeah thank you
