 So, hi, hi everyone so today I'm going to do the final presentation for my internship over this summer. And my name is Han and I'm from UIUC and for the past summer I work on this hyper ledger project, which is hyper ledger Iroha and cactus integration, and my mentors are Peter and Greg. So, next, I'm going to describe what the project is about. So cactus is actually a blockchain decentralized integration to that allows users to integrate different blockchains. It has a pluggable architectures so that the users can, the members from the community can easily integrate various blockchains by creating plugins. So currently cactus already had plugins for Quorum, Xdai, Fabric, Beisu and so on. And in this way characters can utilize these plugins to transfer both the assets and data between multiple blockchains. But unfortunately previously Iroha didn't have a plugin for cactus project. So, my project is actually creating the Iroha plugin so that the cactus and Iroha can fit perfectly together because in this way cactus can take advantage of Iroha's functionality to store data. The technologies I used are TypeScript, Node.js, Express and Docker. For the project initial objectives, so we define that. So firstly we want a documented Iroha connector plugin based on Iroha version one for the cactus project. And secondly, we also wanted documented example of integration between multiple Iroha networks with cactus. And last but not least, we wanted a documented example of integration between Fabric and Iroha. And in the end, my final deliverables were deliverable number one, a documented Iroha connector plugin for Iroha and cactus integration. And deliverable number two, a modified Iroha all in one Docker file and from the Docker file, we are able to produce a Docker image. And also deliverable number three, so one documented example of integration between two Iroha networks with cactus and more specifically it's like an asset transfer between two distinct Iroha nodes. And regarding my project execution accomplishment, so what I accomplished were the predefined objective one and objective two. So namely the connector plugin for Iroha and also as an example of integration between Iroha networks with cactus. So what I did not accomplish was actually the objective three, the examples of Iroha and fabric integration and that was discussed. And my mentors and I agree that we didn't want to do objective three. What I was most proud of was that I was able to support most of Iroha's commands and queries as well as like use unit testing framework as a way to validate them. And I felt that the most challenging task was understanding cactus full architecture, because cactus, I believe is really a sophisticated framework, such that you could support like all various components and in more details, like how cactus works and how cactus is connected to Iroha specifically. For the recommendation for the future work so currently I only implemented the non TLS communication protocol, and I would suggest in the future people could implement the GRPC TLS secure communication for Iroha ledger. And I would also suggest the parameters should be more generic in the future so that parameter changes can be done dynamically. And also, what I accompanied was somehow based on a third party open source library called Iroha helper TS, but in the future, I believe that if we can build our own Iroha helper TS library, which is going to output the transaction status and hash and just on top of the most recent Iroha JavaScript library. And the task could be like more optimized and more suited for our needs. And I also listed a very detailed and complete list for my recommendations for future work, and it could just be seen on this link listed. So I'm also I'm also happy to share my project output and results. So I had to pull requests. So currently the one of them is still on the review and one of them is a pending in merge status. So my first PR, which is a big PR. So it actually composed of my objective one and objective two, and I can show you that. So the first image and the second image actually correspond to the my objective one and objective two. So the first image shows like some parts of the call that I was dealing with the Iroha commands or queries. And the second image shows the example of multiple Iroha knows just communication with with each other and the most specific So in this case the Iroha note one is trying to transfer asset to Iroha note two. And I also have my second PR which was the deliverable to that I described earlier. So which is the Iroha only one daughter file. So this is just the third image is just the part of the Iroha only one daughter file so that you can see like how the Iroha only one daughter contain container image is built from this daughter file. I believe that my the insights again from this summer was that I was able to learn about the typical workflow of an open source project. And how it is developed and how different developers actually collaborate with with each other to maintain a big project and work together to construct a healthy community and my advice for others. The first one is, I would suggest people should have a solid plan in the beginning so that, like you can follow later on. And I would also suggest people to actively, actively reach out to the mentors to seek advice and feedback. And personally, I consistently reached out to my two mentors, Peter and Greg, over the summer and I would also say that learning from the open source communities really very helpful and I indeed I talked to both the cactus community and Iroha community and I gained a lot of feedback and the question and answers from both communities. And with that said, I would like to say a big thanks to my mentors so Peter and Greg and I would also thank the two communities to support my work. I really appreciate it. And so do you guys have any questions I believe I finished almost everything for my presentation. I would like to hand for presenting on your project and insights that you gained through this experience. We do have your mentors Greg and Peter zoom would both of you or one of you like to, would you like to chime in and comment. I will just say, I'll just say that thank you for hard as well. It was also a great experience for me, and it's really good that the code that was written is most likely going to be merged into cactus, and we'll have a full blown Iroha connector out of this. So thank you very much. That is wonderful. Thank you, Peter. Greg. Yeah, it's the first time I'm, I'm mentor. But, but I'm really happy for what Han did. He was doing really good entire three months. And I'm proud of him. Very positive feedback. Thank you, Han, and hopefully this, this experience will be something you can take back to your studies at the university and we hope that you will continue. I noticed that you have a slide on, you know, future work that you're recommending that will come out of this project. And we hope that you'll continue to be involved and maybe contribute to some of those pieces. Yes, definitely. I'm willing to do that.
