 Okay. Hello, everyone. I'm Preetam from India. Currently, I'm doing my final year from Indian Institute of Technology, Patna. For the past six months, I have been doing the project under mentorship of Sai, Peter and Kamlesh. And the project involved were carbon accounting project from labs and cactus from the hyperledger. So a little bit about the project description that were involved in my mentorship. So first is a carbon accounting. It involves two components. The first one is a fabric network which converts where an auditor calculates the emission of a customer electricity based on its utility bill. And the second component is Ethereum smart contract that converts the emission audited by the auditor into a tradable emission token. And hyperledger cactus is a pluggable decentralized blockchain integration tool which allow user to securely integrate multiple blockchain. For the mentorship, the tech stack that I used were TypeScript, Node.js, Express, Docker and HashiCop Vault. Initially, we started with the following project objective. The first one was to build a carbon accounting server that would use hyperledger cactus to integrate with hyperledger fabric and Ethereum. The second objective was to have a proper management of fabric client's private key using HashiCop Vault. And last objective was to prevent the doubles minting problem that was there in the code base. These were my deliverables. The first one was to replace the current dependency of fabric node and Ether package with cactus packages. And the second was to add support of hyperledger transaction with private key stored as a transit engine in Vault server. And third was to prevent double minting of emission token. And the fourth was to build a Vault identity management server for carbon accounting application. For the first deliverable, I made one PR to first to the carbon accounting project. And the second deliverable which was to have a proper management of private key. And this is how it looked at the end. So now, instead of storing the private key of client in some database, and whenever that client make a request, rather than fetching the private key and then signing the transaction with that private key, in this approach, we send those transaction payload to the client and then client sends the transaction. That way, the client private key never get exposed or brought to the application. So for this deliverable, I started with creating one proposal request to the cactus. And then I implemented all the, that was there in the proposal and pushed to the cactus. And using the cactus implementation, I used in the carbon accounting application with this pool request. At the end, the new kind of certification was introduced, which only contain the certificate, not the private key. And the private key were stored in the Vault server. And the third deliverable was to have to prevent a double minting problem. Since there were two blockchain involved, Ethereum and Fabric, the previous implementation had a double minting problem, which I solved with the data log chain code implemented in Fabric. And I pushed the implementation with this pool request. And the last deliverable was to have a identity Vault identity management for the carbon accounting application. The most for what I'm most proud of is the second deliverable that was to have a proper management of a private fabric clients identity. The most challenging part that I come across was understanding the cactus architecture because of its large code base, and because of its lot of packages. And the second was to fully understand the HashiCorp Vault server. Another recommendation for the future work that I would give is to design and implement Ethereum transaction, signing with Vault transaction. This is will be similar to what I did for the Fabric. And to have a UI for carbon accounting project, which will use my implementation of carbon accounting application API server. And the project output and result that I that was generated at the end of mentorship work. Firstly, the carbon accounting application was more stable and was ready for production. And the code base of the application API server was more maintainable because I added a lot of test. And there was and with the proper management of clients private key. There was a double and last double minting of token was also prevented with the Fabric data log chain code. And inside inside that I gained was the this was my first contribution at this scale. So I learned how community driven project works, and I get to work with the peers, a peer developer from across the globe. And the first that I would give to new developer or new mentor would be to have a to design and plan before jumping to the coding part and to have a daily or weekly target and document daily progress and to and reach out to the mentors community member to seek advice. Yeah, thank you. Not a question but I just wanted to say that the pool requests that Jack pre submitted to cactus were very high quality and in general very robust so thank you very much for contributing to cactus you're awesome. Thank you. Great to hear the validation from Peter as one of the mentors. Do we have any questions for pretty much you can see this project is a is in our hyper ledger labs. And it's, I will say has many elements and still at the very beginning of the development I hope that you will continue to contribute and stay involved and potential potentially even give some of the advice to new developers who may be interested in contributing to, to this project. Yes, sure. That the project was really nice and I will be contributing more to the cactus and carbon accounting project. Thank you very much.
