So again, good morning, good afternoon, and good evening, everyone. And welcome to Hyperledger India Chapter's hosted event. So today, it's our honor to welcome two of our esteemed guests from Hyperledger Foundation. First off, we have Daniela, who is Executive Director of Hyperledger Foundation. She's also General Manager for Blockchain, and it's a huge title, so I'm going to Yes, Blockchain, Health Care and Identity, head. That's right, you heard it. And then we have Julian, I guess we are all familiar with him. He's always there for us in supporting in any event or any kind of initiative that we bring up. And of course, as you know, Julian is VP of Hyperledger. And also, he leads some other Linux Foundation activities within Asia Pacific, including the public health rights. Correct, LFPH. LFPH, so yeah. And now the stage is set for Daniela to take call from here. And it's our honor to hear from you, Daniela, or to you. Arun, thank you so much for inviting me. And congratulations to everybody on the celebration. So I have a couple of slides to take everybody through. If I can just figure out how to share this. OK, all right. Can you see my slides? Yes. Yes. All right. Excellent. Well, once again, congratulations on your third year anniversary for the India chapter. It has been fantastic to see from my view over the last three years, how the India community has grown, how you've also taken on leadership opportunities. And we'll talk a little bit about that with the TSC and really the amount of community work that I see on a day in, day out basis from the Indian chapter is really unmatched around the world. So congratulations to everyone. And I'm very happy to be here and celebrating with you today. So I put together a couple of slides. There's been a lot of changes. It is my honor to be executive director of the Hyperledger Foundation. For those of you who don't know me, I've been here at Hyperledger for the last four years, a little bit over four years, working with Brian Bellendorf as the vice president of World Wide Alliances, working with our member community and the rest of our ecosystem team and our community architects and of course, Julian Gordon and the rest of the Asia Pacific team who have just been fantastic as the region continues to grow in India, in China and in other parts of Asia. So it is just my honor to be here today. And I want to just congratulate everybody once again for all the work that the Indian chapter has delivered and more importantly has succeeded in. So congratulations. It is a new era. It's a new, you know, Hyperledger is celebrating our sixth year anniversary coming up this at the this December. And there's been a lot of changes, you know, beyond me taking on as executive director, our community continues to grow. And we've really become a diverse ecosystem of special interest groups of different regional sectors and obviously of different technology projects and use cases. So as we think about as, you know, we we surveyed our membership, we surveyed people outside of our membership around what Hyperledger means and what Hyperledger means now and into the future in regards to Enterprise Blockchain. We really got a great feedback about that the the the name Hyperledger was a bit confusing. People didn't understand is Hyperledger a project? Is it a technical project? It is a community? Is it what exactly is it? So one of the things we we did is once again, we surveyed our members and we surveyed the community to understand what would help to have a clear line between Hyperledger as an organization and the individual projects. So the different projects here as well as the different community sectors, whether it's the regional check chapters like the Indian regional chapter or the special interest groups, the public sector interest group, the climate actions special interest group, how would could we define ourselves as a community and over the years, you know, many people thought we were the Hyperledger Foundation under the Linux Foundation, but we weren't. We were the Hyperledger project and within the Hyperledger project, we have many projects and many six, but we just renamed ourselves to Hyperledger Foundation and I think it's going to really help bring forward Hyperledger and the communities that are built around Hyperledger in in our future. So I'm really excited for those of you who haven't perhaps read about it or have seen it, we are now the Hyperledger Foundation. And there's a lot of materials that we've put together and also published out. Let me see if there's a chat. OK, sorry, it's our Julie Julian's chat was not to me. So there's a lot of materials that we put out. There was a blog post that we posted on why we did the name change and why the focus on building a foundation, a foundation, once again, of communities, a foundation of technical projects, a foundation of regional communities like the Indian chapter, etc. So we did publish a Hyperledger Foundation paper and this is an overview of what Hyperledger Foundation is. It is for both business and technical audiences. And it's a great, I think, document. It's simple and easy to read if you want to share with your employees or others that are curious about what Hyperledger is. It defines on why we exist and what we do. Focus on why Enterprise Blockchain, which continues to be an important definition and thing that we need to educate the market on. And we'll talk a little bit about that later. It outlines the Hyperledger technologies, the DLTs, the the tools, the libraries, and also shows Hyperledger in action, where we break out based on use cases where the technology is being applied. So if you haven't seen it, it's on the hyperledger.org site. If you just go to the about, you can download that white paper and we would love feedback from you all about that. So, you know, as we thought about the name of the foundation, it was also time to, you know, to update our mission. So for about six months, there was a task force. This was a community task force that consisted of different community members that were evaluating the original Hyperledger white paper. That task force also came up with suggestions for the name to change to Hyperledger foundation and also had input on that foundation white paper paper that I just reviewed. So a couple of key things that we thought was important to update in the mission as the Hyperledger foundation and community continues to grow. One was to really, you know, put into our mission that we are the premier community of software developers. The language in the previous mission was not as strong, but we can claim to be the premier community of software developers building these open source software tools. And we wanted to make sure that was clear. We also expanded the scope to include multi-party systems. Using blockchain distributed ledger and related technologies. This is important as the different projects within the Hyperledger foundation continue to grow, where we have DLTs, we have libraries and tools. And this allows us more room for different types of projects, potentially in the future that are really Daniela. Yes, there is some technical difficulties. I'm on mute. I think we lost Daniela. So everybody, if you want questions, I think she'll be back in a second. I imagine she's just had a had a had a had a break there, right? I don't know. Sorry, my Wi-Fi broke again. You need to distribute a Wi-Fi system. Exactly. Well, they're working on it. All right. Sorry about that, everyone. I'll complain to my own loss. So yeah, so let's let's continue on. The Hyperledger momentum, for those of you who haven't seen this slide, this is a standard slide. We use this in all our mid-year and quarterly updates that we do for the community as well, and many of the presentations that myself and Julian and others on staff use. We're really trying to benchmark year over year how the growth of our community. Once again, it's six years since we've launched. So half the Indian chapter is three years old and we're six years old. The amount of libraries and tools and distributed ledgers, the different graduated projects that we now have with version one and above. Obviously, some of the projects like Hyperledger fabric that have TLS releases, so really advancing the projects in the community as a whole. We continue to grow from a global membership. We just had some new announcements of new members with companies like Siemens and others like ID Now and Esperio Blockchain of a services firm in Europe. So we continue to grow both at the members and obviously in the regional communities, the working groups, the special interest groups and the meetups. One of the things even during the pandemic period was really our virtual communities continue to grow and really just produce some great content and some great opportunities for people regionally. So we're very happy with that and we continue to be very supportive of those growths on our project landscape. For those of you who have not seen the new landscape view, we're now identifying graduated Hyperledger projects and incubating projects. We're happy to come in and I'm sure Rune would be happy to do an overview of what that means as a project and there's some great conversations going on right now in the technical steering committee about how else to define these projects, how to make it easy for someone who's coming into the community new to be able to select which projects they should explore and they should be using so lots of great work that the TSC along with staff, I think, will be working on over the next few months. Another place that I think is fantastic that I'd like to highlight is our labs. So when we launched our labs, we knew it was a place to allow people to innovate and experiment. And it's been fantastic to see the type of code code contributions that are coming into the labs. Today, we have over 50 different labs all at different stages. Some are pretty active, some are a little bit more dormant, but really it's a place for any of you who have code that wants to bring into hyperledger that you want to build a community around to do so. So if you haven't, please do take a look at the labs and perhaps in the future, we can do a session very specific to the labs that are happening within hyperledger because it is a source of innovation and experiment in our communities. So let's talk a little about adoption and use cases. We continue to see a growth in the enterprise blockchain use cases, a 2021 Deloitte survey basically said that 81 percent of the respondents, this was about 1200 senior executives and practitioners that they surveyed, so 81 percent agree that blockchain technology is scalable and has achieved mainstream adoption. So what that means is that the technology is there and the senior executives know that technology is is available and working and that they believe that they see mainstream adoption across their organizations, which is great to see. We also did a hyperledger brand survey in the end of the summer. So we released this to our members in September and I'll share a couple of slides with you. There's some additional information that we will be making public. And we asked there was about 200 respondents, both business and technical leaders on where do they see business blockchain technology going over the next two years and basically, you know, 87 percent of the respondents that they see it growing rapidly or moderately, which is a fantastic number to see. Fifty two percent of those said that it was growing rapidly, so very quickly within their organization and their ecosystems and 35 percent growing moderately. So that's pretty impressive numbers. If you think about kind of the the the growth that we continue to see on these use cases and we'll talk a bit about that. Another key thing that our brand survey found is that respondents, so these same 200 executives in both business and technical, the survey respondents view open source as the most appealing enterprise blockchain actually and that is just a fantastic stat because that's what we're here for. That is what the Hyperledger Foundation does is creating open source enterprise blockchain projects. And this is important because we continue to see government agencies, for example, talking about how they are making selections and some of the big implications with open source. So that's the survey really validated a lot of the work that Hyperledger has been doing over the last six years to make open source the most appealing enterprise blockchain attribute. There's been a lot of market education and we're starting to see RFPs and different things that basically say open source and Hyperledger is required. A couple other things I want to highlight is when we surveyed the surveys, we talked about what is the best categorization of blockchain application? What is being developed and deployed within their own organization? And the three top blockchain application categories where financial services, supply chain and identity, followed by education or research, government legal, health care and as others, as you see there on the slide. And this aligns very closely to what we here at Hyperledger see as part of the case studies, for examples that we publish and where our members are deploying and bringing solutions to market. So it was great to validate that as well. So some of the key areas are obviously aligned very closely with where we see the growth of Hyperledger technology. So in payments and finance, and these are just some examples, I'm not going to go through them all with you and we'll make these slides available for you after the fact, obviously the Bank of Cambodia's Project Bakon, which now has recorded over 1.4 million transactions just in the first half of 2021, and that is a CBDC, a central bank digital currency retail digital currency built with Hyperledger Iroha. There is multiple CBDC projects that are using Hyperledger fabric as well as Hyperledger based on I have a slide next to show. But we're also seeing continued adoption and production networks reporting on real data, real production data from the likes of GSBN. Which is the Global Shipping Business Network. Trade Lens, they are now recording, they say they've tracked over 42 million container shipments and 2.2 billion events. I love talking billions, but this is real transactions, real systems that are in production with Hyperledger technology. In the case of Trade Lens and Retrade and GSBN, all three of them are with Hyperledger fabric. So we continue seeing and more importantly, we're starting to see those numbers of ROI, efficiency gains, etc. So on the CBDC front, we're happy to talk a little bit about it. We continue to see Hyperledger very much in the forefront of all the central bank projects that we see out there. So these are just some examples in this includes fabric in Bezu and obviously Project Bakon with Hyperledger Iroha. And I think we'll see more, we'll definitely see more. We've been talking to the central banks, the Bank of England, the Monetary Authority of Singapore, and they just announced yesterday, the finalists and we do have Hyperledger finalists in there. And it's just fantastic to see the continued view of central bank digital currencies looking to Hyperledger first. Once again, back to that book and source first, collaboration, regional access and a commercial ecosystem. They know that there's a commercial ecosystem of vendors to support these implementations around fabric, around Bezu and around Iroha as well. So another key area of growth that we're seeing obviously is providence and supply chain and we continue seeing some great data points from circular, from Walmart. This 10 cent application is reporting 50 percent reduction in warehouse documenting and use cases around pharmaceutical supply chain. We continue to invest in making sure that supply chain and providence and sustainability use cases are shared throughout the community. Last one that I had on the list is identity. Identity not only continues to be important, is being targeted in Europe, in Canada, many major initiatives that are government driven have identity and self sovereign identity as a core to what they need to do. And this is important in things like ID Union in Europe out of Germany and where they're creating basically production level infrastructure using Hyperledger Indy to create verification of identity and finance, manufacturing, public sector and health care. IATA is using Hyperledger Indy and Aries to do their COVID credentialing for travelers. So lots of great work that's happening and continues to work in the Hyperledger Indy Aries, as well as Hyperledger fabric. There's some great identity use cases as well that we can attest to fabric. Our members continue to help us tell that story. We are on track to publish 10 case studies. We just published one by Tech Mahindra around a very cool use case around digital transformation for Abu Dhabi's land registry using Hyperledger fabric. Just this week, we published another case study with SMP Global and Splunk around their use cases. Please do take a look at it.  And we welcome anybody who's a Hyperledger member to contribute those member case studies as well. It's not just our members. Our blockchain showcase, which anyone can contribute to, now has over 100 showcase listings across many projects and use cases. So please do take a look at it. And if you have a case study, your own use case with Hyperledger technology, feel free to submit it. It is open for anyone to participate and contribute to as well. Another data point that I think is really important just recently, block data, their research firm just put out a report around the top hundred institutions of the world's largest companies and out of out of them, 30 out of the 30 technologies that they benchmarked or they looked at, Hyperledger fabric was the most preferred of the top 100. So 26 percent of them are currently using Hyperledger fabric. As you can see here, which is just fantastic to see. And there are some Hyperledger Bezu in here in Ethereum. Well, we're going to get them to start breaking those out correctly as well. But this is just a testament to our community. It's a testament to many of you on the phone who support these large implementations and it's just fantastic to see fabric and other or other projects as well. Community growth without all of you on the phone, we couldn't be where we are today in our sixth year. The three years that the Indian chapter has contributed has been amazing. I'm always we always use it as an example. I'll just give you a story. Yesterday, we had our annual governing board meeting in New York City. We met at the J.P. Morgan offices, all our governing board members, including Joe Lubin and Christine Moy and David Treat. So Joe Lubin with the consensus, Christine Moy with J.P. Morgan, Rakesh from IBM, Archana Shritzi from Walmart, who is the general member representative. We all and a bunch of others met in New York City for five and a half hours. And we highlighted the work that the Indian community has been doing to our governing board. And I think it's important to to to acknowledge that to you all because you're all volunteers and it's just amazing. So once again, I want to thank everybody here for your support in that as we do and we continue to model what you've been doing here in India for the last three years across the globe as well. Have a lot of successes in Latin America and Brazil, which is fantastic to see. Another thing I want to just highlight. We are a global community. We have invested a lot of time and effort over the last year in making sure that hyperledger is accessible in multiple languages for multiple regions. We now host meetups in 13 different languages. We've translated the fabric documentation in eight languages, including Tamil. So thank you, if any of you on the phone today were a part of that contribution campaign that was great to see. We have translated the homepage. We have different courses in different languages. And it's really just part of our growing focus on our regional communities as well.  Many of you here on the phone are part of that commercial ecosystem as members and a vendor directory as her certified service providers. That program continues to grow. We have seen RFP that specifically stated that they were looking for hyperledger certified service providers, so the program continues to be important one and mostly we tell end user companies they don't have to go alone. It alone, they have a rich commercial ecosystem of people like you to support them. So how can you help further? You can join us, you contribute, you can share. So obviously you're joining the regional chapter. There's community calls. There are, there have been some recent discussions around having those community calls also have regional time, especially the special interest groups. I'd love to continue in those discussions and see how we can support, contribute to a project or a lab, as I mentioned before, the labs are a great place to start bringing code and innovation. We're happy to provide that writer blog or developer showcase. We're always looking to highlight developers in the ecosystem. So please, you know, join us for that as well. And last, I think that's the last one, I want to congratulate the two members of the Technical Steering Committee. Arun, as going into a second year and has been an amazing leader for the Technical Steering Committee in bringing the voice of the Indian community into the Technological Steering Committee and Kamlesh welcome and congratulations as well as the new Technical Steering Committee member and both of your leaders in the Indian regional chapter as well. So once again, congratulations.  And I honestly cannot wait to have an opportunity to get on a plane and go to India. Excellent. Thank you, Daniel. That was a great, great presentation there. And thank you. We have now probably 10 minutes of a Q&A. So maybe I'll ask the first question, right? So what does it feel to like to be to be the executive director, right? We're all very excited for you to be the new executive director. But what does it feel like to take on this new responsibility? Obviously, I think many whereas you were doing a lot of a lot of hyperledger anyway, right? But what does it feel? What's your last month been like? There hasn't been a lot of sleep. So for those of you, we made the announcement on October 13th, actually. So exactly a month ago when Brian Bellendorf announced that he was going to be the executive director of the new open source strategy project at the Linux Foundation for security. And we had been working on that transition for a while. So it wasn't like he woke up this morning and on October 13th and said, hey, would you like this job? So we did a lot of valuations. We really made sure we discuss this with the board. I've had full board support from the start, which has been fantastic to see. I've been working with the board for the last four years very directly. So obviously, they knew me. Our hyperledger members know me quite well because I've been working with them so so so long. And hopefully many of you do as well. I've tried to be as public as possible. So it feels amazing. It is one of the things that I was kind of just like anybody who's who's about to get promoted. Like I had some apprehension about it and I went and I had a conversation with Jim Zemlin, who is the executive director of the CEO of the Linux Foundation, and I said, Jim, I'm nervous. You know, can I do this? Can do you think I could do this?  So it's been fantastic. You know, we're growing the team. It's important to grow the team. We're going to bring bringing in some new resources and new faces to help support our member community and our global community. So over the next few weeks, you'll start hearing about those new faces. We also just promoted David Boswell, who had been on my ecosystems team and we just promoted him to Senior Director of Community Architecture to really help grow a lot of the developer community aspects. So it's been fantastic. It's been very tiring. I need a vacation and I do hope to get one over the Thanksgiving US holidays here. But, you know, Julian, you, Dorothy and the rest of the staff there in Asia Pacific have just been so supportive. So I want to thank you. I couldn't have done it without you and the rest of the team. So it feels great. It feels great. And I'm really looking forward to making us all proud and continue to grow. Yeah, that's great. And I think that the whole community here is really supportive and very excited. What you call the next chapter, I think it's wonderful. So we've actually just got maybe just five minutes left. So I'm going to ask two different questions. Right. One is basically we have a lot of people here saying, how do I how do I get involved? How do I find out more about hyperledger? So that's kind of one question. And the second question is there's so many new things happening. We've got NFTs, we've got CVDCs, we've got public networks. So there's two kind of how do we get involved? Literally, if you do this in five minutes, how do you get involved? And what do you see as the kind of new, exciting things and how do we as hyperledger engage in those? True. So, you know, and I see a couple of questions that are, you know, like how so how to get involved? So if you want to learn about hyperledger technologies, right? If you're at that stage where you don't have the technical knowledge or even the business knowledge about enterprise blockchain, we have great courses that are free and online and self-paced for you to take advantage of our introduction to hyperledger course has, I think, over one hundred and seventy five thousand people have taken that course worldwide. We just updated it three months ago, so it's very it's up to date about all our projects and kind of where the industry is. So I recommend that and then start dealing it. There's there's courses around hyperledger fabric to learn to get certification to be a fabric developer or an administrator. There is hyperledger Indie Aries and Ursa to learn about digital identity. There's hyperledger Basu. So we just released in June hyperledger Basu training course. Those are free and available for anybody to take. The certification courses do require there's a fee associated with the testing, but there's lots of resources there to get involved. There are a lot of videos. The YouTube library, if you haven't visited the YouTube library and Dorothy, maybe you can pop it into the chat room is a fantastic place to hear what other community members are building using hyperledger. So I recommend doing that. All our special interest groups get presentations presented there to do that. Continue being involved in the hyperledger Indian chapter and, you know, and build, build, build, you know, grab the code and build some solutions and show us what you have. Excellent. And obviously the community here we've had for three years. It's done amazing jobs and can help and support reach out to run Kamlesh and Vikram and everyone else here and many people. And then let me answer the public blockchain question. Right. So one of the key things I think we all need as a community is to to focus on our enterprise blockchain use cases. But it will, you know, we're six years into this, the public blockchain and the different public blockchain networks will be important. So if you think about Ethereum, Hyperledger, Bezu, and we've had access to the Ethereum virtual machine since Borough came into Hyperledger. But Hyperledger, Bezu is the Ethereum client that can either be run as a permissioned network or as a node on the Ethereum mainnet. You're going to hear over the next few weeks, many new use cases and announcements around companies that want to build using Hyperledger technology and want the optionality, maybe not now, but in the future, the optionality to be able to be on the Ethereum mainnet. If you think about others in our ecosystem, for example, Hedera, Hedera is a member of Hyperledger. They have a plug in for Hyperledger fabric that allows Hyperledger fabric networks to communicate with the Hedera public network. We have obviously Indy is a permissionless network. And there's a few permissionless networks that have been built using Hyperledger Indy. We have companies like Quant, for example, who are building solutions for easy access for enterprise implementations. They recently just did a presentation with Oracle Blockchain on how they're doing tokenization using Quant. So there's a lot of experimentation and a lot of opportunity for enterprises to experiment with public blockchains. And I do think there'll be more, even in, for example, the last Hyperledger UI, and they're doing IBC, which is they're doing the connections into Cosmos and then Cactus themselves is doing Substrate, which is Polkadot. So there's connections. There will be optionality and hybrid tools and solutions out there. And I think Hyperledger is well permissioned, positioned to be a leader in that space as well. How do we bridge enterprises into public networks? OK, thank you, Daniel. There is so much. I'll come back. I'll come back. It's very exciting. I think we've come to the point now. We have to hand over to the to the interns. We're going to go through some presentations, right? And then we have a then we have a networking, which I think we're going to be around for so people can still ask Daniela and myself some questions. So I'm going to hand now back to your run. Thank you. Thank you. Thank you, Julian. Thank you, Daniela, for the great presentation and thanks for the Q&A. I know we have so many questions coming in on the chart and we'll continue to answer them. But I guess now it's the time for us to switch over to our next presentation. So we have Pritam, who is one of our Hyperledger mentee. So as many of you know, Hyperledger runs annual mentorship project and we are very glad to have so many representation from Indian region, especially the amount of work or the quality of work that they have been putting into into the open source community. It's really commendable. So without much due, I would welcome Pritam. Hi. So I'll share my screen. OK, please let me know. Is it feasible? Yes, it is. OK, thank you. So for the past little bit about my introduction, I'm Pritam from a small town in Gopal, India, and I am currently doing my final year from IIT Patnipurna. For the past six months, I have been doing the part time internship with Hyperledger Mentorship under the mentorship of Sai from Carbon Action SIG Group and Peter from Cactus and Kamlesh from our India chapter. A little bit about the project, the involved project. The first was the Carbon Accounting project. This was a part, this is a part of a Carbon Action SIG project. It basically contains the two components. First is Utility Emission Channel. It is a permission Hyperledger fabric channel which contains the audited emission record of customer electricity data. And then other component is Emission Token Network. And this is an Ethereum smart contract which converts the emission data present on Utility Emission Channel into a tradable Emission Token. And the second and the Hyperledger cactus is a decentralized integration tool which allows us to integrate multiple blockchain. And for the mentorship, I use the, I use TypeScript, Nodejust, Express, Docker and Volt. And so these were the initial objective of the project. The first was to have Carbon Accounting project to use Hyperledger cactus. And the second objective was the private key of the client should be properly managed with the HashiCorp hold. And the last component objective was to prevent the double minting of Emission Token. And the problem that was there in the existing codebase. And so with that, there was also four deliverables. And the first was to replace all the direct dependency of the Carbon Emission application from Fabric Node SDK and Ether to cactus packages. And the second was to have a implementation so that the Fabric transaction could be signed by a private key stored in a Volt server. And the third was to prevent a double spending problem. And the last was design a Volt identity management for the Carbon Accounting application. So for the first, I have created, for each deliverables, I have committed to several Hyperledger projects. The first was, this was the initial PR to the Carbon Accounting. And the second was to have a mechanism so that the client's private key is securely managed. So now, most of the developer, what we do is like, whenever we want to sign a Fabric transaction, we first fetch the private key onto the server and then sign the transaction and then send it to the Fabric network. So now the mine approach was to have, rather than fetching the private key, why don't we send the message payload that needs to be signed? And then the signature can be sent to the Fabric. This way, the private key of the client will always be stored in a Volt server. So there you have a Volt server, a certificate data stored that will only contain a certificate of the client and not the private component. So you can see that in the Credential component part, we have only certificate, not the private part. So this was a better way than the simple, simply putting the certificate and private key together. So for that, I implemented this logic into the cactus as well as Carbon Accounting project. And the third objective was to prevent a double minting problem. So since we have two blockchain involved, first Fabric and Ethereum, and one of the logic was there to have a token minted corresponding to a data stored in a Fabric network. So this led to the double minting problem. So and you can see like we first get a valid data from the Fabric network and then corresponding to those Fabric data, we mint a token. And during this whole process, there was a problem of double minting. So with this PR, I solved the double minting problem. And about the project execution and accomplishment, the most, the component on which I am most proud of is the proposal and implementation of identity component of with the Volt server. And the most challenging part during my mentorship was to have to understand the cactus integration because it involves a lot of packages and it has a lot of moving parts. And third and the second was the understanding of the Hashiko Volt server. And there was, I completed all the deliverables, but there was some future work that needs to be done. And first one was that to design and implement the same kind of mechanism like for Fabric, signing the transaction with Volt server for Ethereum. That way, the Ethereum private key and the Fabric private key both will be secured. And the second is build a UI, which will use the API server that I built. So after my mentorship completion, these were the output that I was able to come. There was one carbon accounting API server which is now ready for production deployment. And I have also added a lot of test case so that it can be maintainable and other developer can also contribute to it. And there is with the Volt identity component, the private key management is more secured. And the last is a double minting problem was also prevented with my implementation of data lock chain code. And during the mentorship, the insight that I gained was I learned the workflow of a community driven project like of Cactus and the carbon accounting project. And working with peer developer from across the world. And the advice that I want to give for other new developer and the new mentee is to design and plan before jumping into port. Because this was the most crucial part and it helped me a lot. And set a daily or weekly target so that you do not get lost. And document a daily progress which is and the mentors and the community members are always to help you. Thank you. Any questions? Awesome. Yeah, Preetam, this is awesome and your collaboration with Peter and the rest of the team there is just great to see. And I know Arun is putting some notes on the chat as well. The mentorship program here at Hyperledger is critical for a lot of core projects. So next year we'll do the same batch of mentorships. But folks like Preetam, really thank you so much for your contributions. I think it's hopefully you had a good experience. Sounds like you had a great experience and was able to move some of those initiatives forward that the Cactus team was looking for. Yeah, thank you. Awesome. And I guess Preetam, there are questions on the questions asking about sharing the links that you have worked on on the chat. So you can share those. And thanks again Preetam and we know you have a busy schedule today and all the best for your examinations. Yeah, thank you. And we look forward to having great collaboration in future with you and also many more contributions from you at Hyperledger. And now we will switch over to Harish who is another Hyperledger mentee from the India region. And Harish, the stage is set for you. Sure, thanks Harish. Hi guys, I would just present my screen. Is my screen visible? Yes. Hello everyone, I am Harish Multani working as a blockchain developer at Ayaanworks. And my major tech stack is Indie, Ares, Ursa and Fabrik. So I was involved with the Hyperledger community from 2019. I've been working in Fabrik from 2019, started with sample POCs and then shifted to Ayaanworks and started working on production projects. There I got to know about the Hyperledger India chapter calls and started attending that. And when I was involved in this call, then I got to know about various initiatives that Hyperledger India chapter carries out like HyperHack 2021 they did. Then I got to know about the Hyperledger mentorship projects. As you all know that there are various projects under Hyperledger, there are around 16 Hyperledger projects. And the use case that I have seen in these mentorship projects are whenever these 16 projects are being used by businesses, they operate globally and they operate around different parts of the world. So every time there is some or the other new opinion that comes out, which leads to a feature being implemented. So these 22 projects are similar like these are features that we are implement that Hyperledger has seen and they wanted to be implement on different projects like Fabrik, Aeroha, Baro, Cactus, Caliper and Ares stack. So what I got to know about this is whenever these projects are being used by different businesses, they would always come up with some or the other different opinions. That would lead to, you know, new feature being implemented. So similarly, then I was implementing a project on Hyperledger Fabrik and Aeri integration to support Fabrik as a blockchain ledger. A little bit about this project, as we all know that Fabrik is the most used blockchain platform till now, as we just saw the insights from block data. And what they needed is suppose now a business is building a supply chain management solution using Fabrik. Now what they need is, now if they need to verify some or the other identity in that blockchain, they don't want to keep the identity related metadata on a separate ledger, which would be indeed in our case. So the business building the supply chain management solution, they don't want that our supply chain related data should be on Fabrik and the identity related data if we need to verify some identity that should be in indeed. So they wanted that, they wanted that the same data should be there, both data like supply chain management data and identity related metadata like credential definition or schema transactions should be there in Fabrik only. This was the, this was, this way the, this way this project arise, which involves supporting Fabrik as a blockchain ledger from Aries. So now Aries only supports India as a blockchain ledger, but after this need, there was a support to add Fabrik also as a blockchain ledger. So basically what we did here was in India there are three types of transactions that goes to the ledger, domain transactions, pool transactions and conflict transactions. The pool and conflict transactions that goes to the indie ledger are related to the indie network setup. So we don't need to do that at Fabrik because Fabrik there are different transactions that would be, that would play the role similar to what role is being played by the pool and conflict transactions in indie ledger. We only needed to support the six domain transactions that indie supports. Those six transactions that indie supports are the DID transactions, atrip transaction, schema transaction, credential definition, revocation registry entity and revocation registry definition. I would give you a bit about these six transactions. Did is a identity of an issuer that, that is registered to the ledger. It is registered with the public key of the issuer. So in a DID transaction, a DID document goes to the ledger, which includes the ID that is the DID, the public key that is where key and the endpoint of the issuer agent. Any agent for that matter. Then there are schema transactions that goes to the ledger. Now say suppose I am an issuer issuing a credential, an identity credential, where the attributes are name and age. So the schema would contain these attributes, name and age. So this goes to, this is, goes to the ledger from the issuer agent. Then there is credential definition transaction. Credential definition basically includes the public keys of the issuer. The private keys of that correspond to these public keys are in the issuer's wallet, which are used during signing. And the public keys that go, goes to the credential definition that goes in the credential definition to the ledger are used during the verification process. Now, like stop me if you have any questions in between them. The fourth transaction that is. Just one. I was wondering just in case, you know, you are showing a PPD. We are looking at Chrome, right? Yes, yes. Sorry, sorry, don't interrupt that. Okay. I have a presentation lined up maybe on 20th and 27th.  No, thank you. Sorry for it. So the fourth transaction that I was mentioning about is atrip transaction. So here the, and basically atrip transaction is the transaction that updates the DIY document that already went to the indie ledger. The main update that happens here is the end point gets updated of the agent. Then there is revocation registry entry transaction. Here the, here there is one accumulator that goes to the indie ledger, which is used when a user is creating a proof to check whether a particular credential has been revoked or not. The revocation registry entry along with the revocation registry definition transactions is used by the user so that he can make a proof of a particular credential if the credential is not revoked. The entry transaction includes the accumulator and the definition transaction includes the witness delta. I would explain the whole process, maybe in the upcoming demos. And so these are the six transactions that goes to the indie ledger. So what we did here was we set up a fabric network and we make instead of these transactions going to the indie ledger, we directed it. It goes to the fabric ledger. So we didn't do any changes in the payload. Same because we wanted, we took the same payload that indie modules generate and we send it that send that to the fabric ledger because if in future some changes happens to the indie module or those payloads, we won't need to do any changes such that it also supports fabric. So the need won't be there and if in future some changes happens to the indie module, it would be, it would work with fabric also. The thing that I learned that my learnings from here was basically on fabric networks, specifically Docker, Docker network and how hyper ledger fabric is set up on your system and on cloud. And I got to know I got to read a lot about I read the fabric documentation and got to know about how the fabric network operates. We have some future plans for this project. In future we may or may not include support for other ledgers based on the based on the need is the business needs we may we can easily integrate support for sort of any other ledger for that matter. And one more plan that we have for this project is integrating the indie wallet with fabric wallet, such that both credentials related to fabric identity credentials and in the identity in the credential records schema records are kept at the same place. Ask a question. So currently, at the end of this in your architecture today you have both hyper ledger indie and hyper ledger fabric is hyper ledger indie is helping you manage the identity and hyper ledger fabric is helping you manage the business transactions. The question was, do you have now in your architecture you have both hyper ledger indie as well as hyper ledger fabric is. As in, we are integrating the fabric support in areas framework JavaScript, it is, and once that is done, the areas framework JavaScript would be able to support indie and fabric both as a legend. So we can define which we want to use the business that would develop the solutions, SSI solutions using AFJ, they, they can decide whether they want to use indie or they want to use fabric. Got it so basically if I understand this right so today with the solution that you have developed, I can use hyper ledger fabric for both decentralized identity and decentralized business transactions both. Yes, yes, sure. This was the need of the project because businesses like fabric today is being used in major shipping supply chains, textile supply chains. And in PBC projects and then in telecom projects to these businesses wanted to implement the identity verification workflows, mainly the self sovereign identity they wanted to implement. So we wanted we added that support in AFJ for now that would support fabric and India fabric as a legend. Thank you. Any more questions. So you said like you deploy this application in cloud, which cloud provider you're using. We are, we have not yet deployed it on cloud, we are, we are first, we would first demo it on local, and that that works, we would move it to cloud. We would test it with cloud. Okay, which is preferable. I mean, whether AWS or JCP. I have like, I have been whenever I was working in my company project. We are using, we are using AWS. Okay. So I basically use AWS. Thanks. Thanks, Arish. And, and, hey, so Dan, I believe the preferred cloud service provider would be when we deploy these projects. And probably what harsh wanted to say is the mentee project would enable support for a cloud deployment. So thanks, Arish. I guess now we have now reached a time off for networking and also celebrating the third anniversary for India chapters. And we definitely would like to thank all of you who have been supporting us for the last three years and in growing the community. Right. So we couldn't have been here without your support or continued support in terms of any contribution that you have been putting in. Not just the code contribution. So our type of ledger we have any type of contributions that you can possibly put in like you can possibly think of. You can participate in terms of improving the documentation you can participate in reaching out to additional like spreading the word about hyper ledger project or you can even participate in the special interest group if you are a subject matter expert. All ways participate in working groups and which are time bound and which are specialized in certain areas to work on, and you can always contribute to projects that eventually you will end up using. Right. And, yeah, there's a lot more so I would probably welcome Julie and to speak a little bit more about that.  So you want to talk about how people get involved or get involved in projects. Yes, and also Julian if you can bring out the contributions done from India chapter, like starting from the first lead, right, like the way I'm all get got it all started. So you travel to Bangalore, three years ago. So if you can share some memories about that, that would be great. All right, so I got to dig out of my memory lots happened in those three years my goodness. What a journey. I mean this has been amazing I've been hyper ledger since that since I think five, six years now right. When we started off we had a technical working group in China, and I think it was three four years ago, we had this discussion actually Brian and and David Boswell, and a few others are saying how do we, how do we expand to help these communities globally right. And we came, I met up with with the technical steering chair at the time that and I also met up with a mall, I think we met in Switzerland was it a mall. It was right. It was in Switzerland that's why you've got those mountains in the background I didn't think Bangalore right. So we met up there in Bangalore and we thought about we planned this right as a new and decided rather than having a technical steering committee want to have a broader remit right. And they came up with that with the concept of a chapter, and a mall really you took that forward. We took that to the technical steering committee it got passed. And the rest is history, I think. It was launched during Brian's visit to Bangalore. Exactly. We had a lot of the industry leaders here. And that's when we formally floated the idea and we kick started that started off with with a very small initial meeting and look how it's grown and it's really a testament to the community and to folks like Arun and Kamlesh and Vikram and Rajesh and all the others who contributed so much towards towards this, this community in the last three years and of course, a lot of support coming from hyper ledger itself, from Julian and David and and Brian. Okay, I have to thank you more because you really did you took on you took on it it was a it was a new journey, and it was a new, a new construct which we put together right. And I think it's hyper ledger is one of the first kind of big limits foundation profits that's done these local kind of local, because in the end, think local act global, it all makes sense right that's how you scale. And that's how you get deep community. And we've had, you know, in terms of projects in terms of translation. We've had some of the some translation here to some of the local dialects in India. And we've done many, many, many projects and it has grown and grown and grown and then, as you say, you then handed over the mantle to Arun and Kamlesh. And we've had a university chapter. We've had all kinds of interesting kind of subgroups were very active on LinkedIn. We have I said weekly meetings which everyone is welcome to write. We have a lot of mentors mentees people are maintaining projects in India and I think that's grown and grown as well. So I think it's been a very, very successful and obviously as a, and obviously with Kamlesh and Arun they're also a bridge to that technical steering committee. And one of the reasons we really set it up is one obviously India on the prolific developer communities in the world, one of the largest right and great expertise right is time zones. So a lot of these meetings is I think Arun was saying we're going to have the mentees stuff but it's going to be late right. So what can we do in this time zone to get more people, more people involved. It's great. And I would Kamlesh you'd like to say anything as well so Kamlesh is I can see Kamlesh now on camera right. You're in a car. I love this Zoom world. So actually I was driving so I stopped at the highway. So I want to say some words. So, I think I associate with the India chapter from last three years when he started with Amol and Ajay to the community in the global front. And then we, Arun, myself and lots of other volunteers started contributing and helping community to build in a good prison. And then I represent to the Julian Dorothy and the brand is basically coming to the events and make the end of the successful in chapter. So, yeah, thanks to you and everyone and welcome Daniela and we are looking for the similar kind of contributions and stronger community in India. Excellent.  That's excellent. Excellent. So yeah we have a great community activity and I think the platform, we keep them raising the threshold of activity right. So, so thank you Kamlesh and I think Daniela it's great to have you here right. Great connection with Brian I think we're in great connection with what you're going to be doing here. So, I think I celebrate. We are going to be doing here all together. Yes, so we're going to be doing here together. So, you know, it's all about people it's all about community right. What we do here at Hyperlation as we say everyone is welcome so the more people involved the more diversity in our community the stronger the community so and the inner community has really really stepped up. The community I think lots of stuff that Arun did, like we did the, or Arun and Kamlesh did in terms of the hackathon right I think that was an initiative that had not been done before and you had. I think someone from Hong Kong won it in the end right the first, the first hackathon, just to show it's not just about India. It's about also India supporting the community around the world right so it's been an amazing, an amazing journey and we look to continue. Does anyone else want to, to, to reach out anybody else who has a Vikram you'll be involved a lot as well and others. Anybody else want to say anything, or we can go into the, we can go into the, into the network. Yeah. Sorry Vikram, yeah. Yeah, I think you know definitely you know I would definitely like to say that you know I have been associated with you know India chapter for about the last two years. And I think you know the hackathon was the one which got me initiated with this chapter and you know I have been since you know with this chapter since then. And you know we have seen this community grow and you know along with Hyperledger we have seen you know Hyperledger grow a lot. And similarly you know Hyperledger India chapter grew a lot. And you know it is a great place for anyone you know who are today on call to you know so to join our you know it would be great you know if you join our you know weekly calls on Thursday. And you know so we discussed what is happening with Hyperledger and you know what is happening with the community around. And also you know we have used that opportunity to help people who are struggling with Hyperledger fabric or maybe even you know with the technical issues or you know the technical questions. So I think you know it gives a holistic I guess you know support to that community so you know and you know community is as strong as you know the community members I would say so yeah. That's great. That's great and I don't you go do you want to say anything about from chain yard one of our members also she goes been involved a lot. I'm just picking people out randomly it's very cruel. Hey Julian thank you very much. I appreciate your your calling my name and remember me yes, I mean it has been very active in the in overall markets plays as well as I say one of the very first Hyperledger certified service provider. In India, I mean I've been working with, I don't know no more. I think I think the view your first visit to in the light I still recall you and Brian and anything as a mother and everybody. So, I think there's a lot more we can do. I'm sure about that but lot we have done. I think going to have a very, you know, three years of time to set the baseline. And, and there is from that you know you can use as a starting board. I appreciate that. Excellent. I'll stop picking people out now. So, yeah, thank you. Thank you. Thank you everyone and I think for new people here who are not involved reach out to anybody I think everyone is very supportive to help people make that connection into the community. So we're all here here together, a common purpose to help the community advance blockchain and work, you know, and help the Indian community and the global community. So I'm going to hand you back to a rune now I think we're going to do some networking and some fun stuff right. Awesome. And thank you everyone. Thank you, Julian. Thank you, Daniel and thank you all the pre mentees free to mind. And all the other mentees who are going to come and speak to us in the coming weeks. So I'm going to stop recording will venture into networking session. It's going to be open for everyone where we can all join in and random breakout rooms and speak about all the things right so how to get involved in the community will also have volunteers or moderators in each of those breakout rooms just to guide you around. If you're stuck somewhere. And also coming next week on 20th. We have great presentations lined up actually a panel by GGO and and also there are too many great events to look out for including we are going to have a blockchain in agritic space. We are going to speak about blockchain and tokenization space we are going to speak about blockchain and healthcare. So there's so much to learn over the course of next three weeks and we look forward to having similar participation from you in the coming weeks. So I'm going to stop recording now and we'll jump into networking session.
