Welcome to Hyperledger Tokyo Meetup. So this meetup is meant to celebrate the fifth anniversary of Hyperledger. Together with Brian Berendorf, Executive Director of Hyperledger. So this is the kind of schedule. So first of all, you know, Brian will give the brief update of the project, as well as, you know, a brief Q&A session, what we call Ask Me Anything. And then we will have a panel discussion together with Japanese board members of Hyperledger. Suzuki-san from Fujitsu, Shirai-san from NEC, and Chou-san from Hitachi. Then from 2 p.m. in Japan time, we are going to have the presentation from Entity Data for 30 minutes. Then from 2.30, we are going to have a presentation from Sora Mitsu. Then we're gonna be finishing up the event around 3 p.m. So important notice. So I'm gonna be doing this important notice for both in Japanese and English. So first in English. So as I mentioned, this will be the conference-style meetup. So we're gonna be making this more interactive, you know, compared to other virtual Hyperledger meetups we had in the past. So you can use your microphone and camera. And your status will be changed from attendees and panelists as I mentioned. And this will cause the temporary disconnection. But no, don't worry, it will come back. And also please make sure to keep your microphone off as I mentioned. So maybe your microphone will catch some background noise. So please unmute it when you speak up. And also you can ask questions any time by pressing the Q&A button.  In many cases, you know, bottom of the screen. Then type question. And please indicate any past event, additional questions in the discussion section on the Hyperledger meetup page as well. And soon I'm gonna be asking, as always I'm gonna be asking short surveys before the session. And before I get started, I'm gonna be announcing a few news. So Hitachi, a premium member of the Hyperledger has become the latest certified service provider. And in Japan, NEC and Hitachi, the two companies who has become the certified service provider of Hyperledger. And also there are other virtual Hyperledger meetups not other than here. And this week, because now we're going to celebrate 50th anniversary of Hyperledger, we're gonna have three conferences. One is in Sweden and the other is in Atlanta, Georgia. So that's gonna be in the United States. And on Saturday, there is one in Eugene Portland. So for further detail, you can click the link. In the meetup page. So please enjoy the meetup. Thank you so much, Nori. And actually one thing that we might do to capture the same sense of where people are dialing in from is if in the next few minutes inside the chat window, if you could send to all the attendees just a one line of the city or the region in Japan that you're calling from or where else in the rest of the world, the country or the state, that might be a really fun way to see where everyone else here is from just to kind of get that sense of community on the call. Thank you all very much for coming and spending some time in the middle of your day. It's only late evening here, so it's a perfect time for myself as well. And I'm sure here with a couple of other participants from the team, Daniela Barbosa here in San Francisco as well as Julian Gordon, who's based in Hong Kong overseeing the rest of our Asia Pacific community. Hyperledger is really a global effort. And just before I dive in a bit to the content, this has been obviously a really challenging year. I saw the economists call this the year that everything changed and it certainly did. And this has been a year that's been tough from an economic point of view for sure for many companies and for many countries, but it's a year as well where the need for blockchain technology has only gotten stronger. We've seen it called up to serve in the purpose of making our supply chains more resilient and more effective. It's been called up in service of looking at how to manage research and development processes. It's been called up to serve potentially for credentials around vaccination status to make those more digital. We're going to see a lot of additional use cases I think emerge as we all try to build back better to use the words of the next president of the United States. We're all looking forward to that as well. But in the meantime, I think the importance of blockchain technology and the relevancy of it to really building a global ecosystem and making it something that can respond to crises and threats has really emerged out of this past year. And we're really looking forward to applying it not just to the continued fight against this pandemic, future potential pandemics, but also to other major crises out there in the world. From the climate crisis to expanding financial inclusion to all sorts of other ways in which blockchain technology can have a positive impact. So let's spend some time talking a little bit about where the hyperledger community has been not just this year, but for the past five years which has been a really amazing journey. And then I can't wait to jump into our panel conversation and talk about how we're really seeing that apply to Japan and to the opportunities and the circumstances here. So let me just get my mouse in the right place. So our official birthday is actually today, the 17th of December, that was when an announcement was sent out by the Linux Foundation announcing this new project called Hyperledger. And I saw that, I won't go too much back story but I saw that while working at a venture capital firm actually, very skeptical of all the Bitcoin kinds of companies that were coming to seek funding, but recognizing there was something to this idea of the distributed ledger of a single source of truth, of a cooperative network built under just a very different approach than the centralized client server models that we've all grown used to. In the five years since then, we've grown to an amazing family of 16 different projects underneath what we call our greenhouse, right? And this is really to illustrate these projects all have a life of their own but they're also all interdependent and our job at the Linux Foundation and Hyperledger has been to help grow that ecosystem, help provide the nourishment for the plants in the greenhouse and many of them have gone on to amazing things. Four of them have hit a 1.0 production release at the least, a couple of them have actually touched 2.0 as well, one of them has. And this is a sign of production readiness. 1.0 in our world, I think is a sign of much greater conservative like this is really ready for production use rather than say what a typical company might call or a typical project might call it's 1.0. We've been in production now with these blockchain networks for three years of those five, now perhaps even three and a half and really started to see some impact. So we've seen this space really being mature. Another measure of the maturity of the space and really of our ecosystem has been the emergence of what we call certified service providers. These are companies that have qualified their ability to provide products and services around Hyperledger technology by employing people who are certified themselves as administrators and developers around Hyperledger fabric but of course, we're expanding that to other domains as well. We have a very active community working groups and special interest groups and I'll cover those in just a bit, 170 meetup communities worldwide through this pandemic, many of them, perhaps most of them have been holding virtual events, virtual conversations, keeping their local communities together but now using virtual tools to reach out to a global audience and to have global speakers at their local meetups. It's been really amazing to see just this year 70,000 people have participated in a Hyperledger meetup. And we introduced a concept recently called regional chapters for those areas like Latin America and the Indian subcontinent where there are actually a very large number of cities each with their own Hyperledger community and we felt it was useful to bring them together. Many of you have seen this picture. This is really our portfolio. This is the Hyperledger greenhouse and these are the 16 different projects that make us who we are. There are a lot buried inside of Hyperledger labs I'll talk about in a bit but this was really a year for many of the participants of the community to shine as well as for some new projects to join as well and I'll cover some of the new ones. I don't have the time or the opportunity to go in depth on all of these projects. And in fact, one I wanted to spend some more time on was Hyperledger Iroha, but I know that Makoto-san will be speaking to you soon in the next hour about Soromitsu's work with Iroha and their work with the Cambodian government around their central bank digital currency and he'll go into depth on those. But I'll talk about some of the projects in just a bit. One of the things we introduced this year was a weekly newsletter really immersed in the technical details of what's going on every week in the Hyperledger technical community. So changes to code, noteworthy pull requests, technical articles, really a nerd's paradise so to speak, focusing on what's happening and where across the different Hyperledger projects. So really encourage any of you who are developers even if most of them will be on projects you don't touch or work with, it's a great way to get this awareness of what's going on in the community. So the two projects I do wanna focus on as kind of bedrock projects for us. One is of course Hyperledger Fabric. Fabric hit a 2.0 release earlier this year and finished off 2020 just two weeks ago by releasing Hyperledger Fabric version 2.3. And 2.3 is really the latest one it introduces some interesting new features essentially provide better privacy and scalability. Also allows for snapshotting of the ledger to make it easier to bring up new nodes without having to reprocess the ledger, do backups all those interesting kinds of features that really about management of these. 2.2.1 is the latest long-term support release though and it continues the tradition of LTS releases that serve as a bedrock for commercial stable deployments worldwide. And of course Hyperledger Bezu, which is now in its second year of existence as a Hyperledger project. This is the client that's designed to the Ethereum Enterprise Alliance specifications. It also works as an Ethereum mainnet client and they've also recently switched to a different kind of versioning strategy one based more on year and then month something called Calvary, but they continue to post new releases with new functionality improvements, new performance improvements and privacy improvements and staying very closely aligned with the mainnet but really focusing on functionality for permissioned blockchain uses as well. So a great tool for building a bridge between the permissioned and permissionless worlds. We also saw two new projects join this year that are really exciting and worth everyone's attention. Hyperledger Avalon, which is a toolkit for doing confidential transactions using either secure enclave technology available in for example, Intel's chips and other CPUs that to use to store keys and perform operations within a secret kernel or to use zero knowledge proofs and zero knowledge circuits to perform the same thing in a trustless environment. So some really exciting stuff that are happening at a cryptography level to try to really balance out the transparency benefits and traceability benefits from having data on the blockchain with the confidentiality that modern businesses need around their data. I also knew as this year is Hyperledger Cactus and Cactus came to us through a collaboration between Accenture and Fujitsu. It was really great to see those two companies who had also, who had each been working on their own approach to building bridges between networks based on Hyperledger Fabric and other networks based on Corda, other ones potentially based on Ethereum Hyperledger Bezu and Quorum which is another major enterprise blockchain tool. It's really a system for integrating the transactions and business processes that have to exist across these different networks. It is still early days, it is not a one-dotto release just yet. They have done a major re-architecture internally and are really eager for people who are experienced with these different ledger platforms to evaluate it and make sure that it's getting the approach correct. But it's a really exciting approach I think to answering people's concerns about how do we deal with the complexity of a world with many different blockchains out there? And so we're really eager to see it. We also have invested quite a bit this year in building up the accessibility of these communities and new contributor pathways to bring new developers and developers who don't feel confident, getting in the middle of the code in some really highly critical spaces but want to contribute on the periphery, want to help not only fix bugs and add features but also make this more usable for a wider audience. And so one of those projects has been something called the Hyperliter Fabric Documentation Working Group that has worked with a number of teams around the world to improve the access to that content in languages such as Portuguese, Japanese, Malayum, Spanish, Russian, Tanal and French. And this is now making a fabric available to more than a billion people who speak these languages, which is really exciting. And in fact, that's led to the core parts of the Hyperliter Fabric Documentation now being localized and translated to Japanese. Yes, we know there's automated tools to do this and they're certainly helpful but we think it was pretty important to make sure that there was a correct translation and working with teams for whom this is their native language, their local language to make sure it was correct. We've also localized much of the Hyperledger website to Japanese as well, again, to make it more accessible to the audience. So really appreciate all of the collaboration we've had perhaps with some of you out on the phone, out on the call in making these two efforts a reality. Time is short, so I won't go into a lot of depth on some of the projects that are burbling up in Hyperledger labs but there are quite a few that we're excited about that are really about making these technologies easier to integrate with things like Kubernetes with other enterprise systems and represents really the kind of distributed innovation that we're really hoping to see. I did mention the Hyperledger certified service provider program that is now up to actually 21 participants. I needed to update this because we just had one join and qualify this week from China but I'm very much appreciative of NEC and, sorry, I'm blinking, and NEC and was it Hitachi? Hitachi, Hitachi, yeah. Hitachi, yes, thank you. NEC and Hitachi for being certified service providers. Thank you, Daniela. I'm going blind, I was looking for that. As I mentioned, our meetup community is just exploding. We're getting greater regional collaboration now around the world. I mentioned Latin America but Africa has turned on in a big way for us and India has been super participatory. So this is great. Five years in, this is the kind of footprint that we really wanted. We knew that blockchain technology would be a global effort. It's really most applicable to those business processes that cross borders to things like supply chains which have very long distances for almost every product now between where the products start and end and Japan's leadership in this field and in building and managing many of these global networks is unparalleled. So we're really happy to see the adoption there in China.  Lots of community engagement is even beyond the code especially in these things called special interest groups which we'd love to have any of you involved in but nine different topical areas in healthcare and telecom in climate change and social impact and trade finance. My guess is that all of you are in a sector that is touched in one way or another by at least one of these special interest groups. And so if you want to see some conversation and engagement about how hyper-religio technologies are touching that domain, transforming that domain we'd really love to have you. And in fact, it's just one example the climate change special interest group which is really the climate action and accounting one has a number of interesting projects underway that involve collaborating around code to implement all sorts of systems to help us perhaps get back to a point where we can implement the Paris Accords and look at tradeable permits for emissions and that sort of thing that'll help us cut the emissions of carbon globally. That's a really exciting space and I'm so happy that hyper-religio can have an impact there. I'll just end with, we had for many of us the last face-to-face event that many of us went to at least here in the States was the hyper-religio global forum event in March which was a well-attended event, lots of great stories. This is something we hope to do again. We don't know if we'll be able to do this next year. It'll all depend on a lot of different factors of course. We did have a successful virtual member summit in September that was really well-attended and I really reflected again the global nature of the community by rotating the time zones so that we were local to Asia Pacific to Europe and to America. But just the scale of our member community now requires us to go where people are and try to work with them at their time zone and with their culture. So we were really happy to have this face-to-face event but we're also feel in some ways even more productive now that we don't have to all get on planes and fly across oceans to be able to meet people and collaborate and work together. And I think that says a lot for the potential. Let me end with this because at Hyperledger we've really been dedicated to building strong communities and strong communities are made out of diverse participants diverse in all sorts of ways. Geographic, gender, culture, the kinds of businesses they work for and that is a strength and it's a strength that we've championed at Hyperledger. It's one we've focused explicitly on and especially on the geographic and gender diversity topics. We would love participation from those of you out there in the community who have not yet really joined the community in one way or another to participate because this is something growing ever in importance to us and to making sure we're building technology that's appropriate for the world. And in the last five years again just the footprint we've developed I told somebody at the beginning of my stent on Hyperledger which was started about six months after the launch. I said, we will have succeeded if we managed to make blockchain boring. And in some ways, I think we have and we might have over succeeded on that to some degree but it really I think has become accepted as a part of the modern enterprise toolkit. The challenge as always has been enterprises operate slowly they operate carefully, they don't tend to jump just on the latest trend only now are we seeing enterprises really jump on cloud computing for example which is nearly 10 years old. So I think if we look at these technology trends cloud computing or even the internet before that we are right on course for Hyperledger in particular but blockchain technology having the same foundational impact that these others have had all it takes is patience, collaboration and community building and that's why we're here. So why don't we move ahead to the panel then? Okay, great. Well, we've got an amazing panel put together of organizations and individuals who have been major supporters of Hyperledger from really the very beginning and it's really been a pleasure to work with them on the Hyperledger Governing Board and as part of our community. Let me quickly introduce them then allow each of them to introduce themselves and talk a little bit about the role that their company has played in the Hyperledger community but also the blockchain projects that they've undertaken. So first let me just introduce Toshia Choson from, sorry, Toshia Choson from Hutachi. Thank you Toshia. Let me also introduce Hiroki Suzuki-san from Fujitsu. Thank you Hiroki. And let me also introduce Makoto Shiraisan from NEC. Really, thank you, the three of you. I couldn't ask for a better panel to be engaging with the Japan community. Why don't we start with Toshia? If you don't mind, would you tell us a bit more about the work that you've done with the Hyperledger community but also on blockchain technology? All right, thanks for your introduction and I'm Toshia Choson from Hutachi. And it's been five years as a governing board member. Maybe I'm the oldest member in the Hyperledger community in Japan and I'm very pleased to be a part of the community like this. And Hutachi always tried to contribute to the enhancement of the especially Hyperledger fabric and we tried to implement or experiment the blockchain technology in Japanese market or not limited to Japan but in Singapore or somewhere else. And actually it was a little bit tough and from the beginning maybe the former CIO of the Deutsche Bank once told us that it would take the five, 10 years to see the real implementation of the blockchain technology. And five years have passed and we are still looking at the new opportunities to get into the actual implementation of the blockchain technology but we are on the way to the success but maybe we need more time but we will try harder to have a quality enhancement of the Hyperledger and try to find out the actual implementation on the actual business of the blockchain technology. Thank you. Thanks Toshia and then I want to highlight Hutachi was actually the first company to sign up as a Hyperledger member. They signed even before IBM, even before JP Morgan. So that is very cool to note and I just want to give full credit for that. Perhaps Makoto share eyes on. You could also share with us kind of your role at NEC at the work that you've been doing and in the blockchain space, the work you've done with Hyperledger but also what are your customers and clients working on in this field? Okay. Thank you. So I'm honored to be here. My name is Makoto Shirai. I work for NEC as a general manager of enterprise business unit. My responsibility is to provide the digital platform and solution using cloud, AI, biometrics and blockchain, of course blockchain and the NEC joined Hyperledger community from 2016 as a silver member. And next year we changed to the premium member and our contribution is to provide main BFT, Byzantine for Trans, consensus protocol to the lab. And this is achieving a high transaction throughput so yeah. Anyway, congratulations and many thanks to the community for this five year. Thank you. Thank you Makoto. And Hiroki, do you think you could share with us some of the work that Fujitsu has been doing and perhaps some of the work that you've done with your customers to deploy Hyperledger technology out there in the field? Sure. I'm Hiroki Suzuki from Fujitsu and I'm glad to be here for celebrating 5th Hyperledger anniversary and myself I have been joining as a governance post since 2017 meaning that I have four years almost four years of experience in this community. And my role in Fujitsu is providing a software product and also the cloud services. So those are the main roles and some of our product services are also based on the Hyperledger technologies like a fabric. And then providing those software and services, our system engineers team is building the enterprise systems for each of the customers in the variety of the industries. And as Brian mentioned earlier that our company has been contributing especially in the Cactus project which started this year officially and the main reason is that I know that the Hyperledger project has been improving, growing dramatically but I see that some of the most of the use cases is focused on the particular reasons, right? But we realize that by connecting to the different type of blockchain networks we can create much more value for each of the blockchain networks but also we can generate the ecosystem. So for that reason we started the Cactus project with Accentures. So that's the main contribution we have done but as you know that the Cactus project is the very early stage so that in the sense that we don't have any actual use case for the Hub Cactus but we do hope that we can develop some use case in the future. That's all, thank you. Thank you. Thank you. Now I'd love to ask the panel what are the most significant or really promising use cases that you've either seen out there or hopefully directly worked on that involve blockchain technology and hyperledger technology in particular? And it doesn't have to be a lot of them like what's the one that you think is the most interesting and is likely to create the greatest amount of value for everybody in the next year? Why don't I start with Toshia? I think you're on mute Toshia. It's okay. The most significant use case would be supply chain management and we can find out the bunch of use cases for supply chain management but in my sense we are dealing with some projects like information sharing beyond the multi industries and some kind of the information will be shared among the multiple companies to bring the convenience to a more higher level of services and it is not limited to hyperledger but sometimes we are using Ethereum enterprise Ethereum or sometimes we will use R3 Coder but such kind of the information sharing would be promising to us and we are establishing some consortium to deal with such kind of information sharing and I believe that the supply chain management or information sharing would be the most significant use cases for us. That's great and just to follow up on that question we've heard of supply chain use cases in food, in diamonds, in sneakers and apparel is there one product category that the supply chain you think is going to most dramatically like the use of blockchain technology will most dramatically impact? Any kinds of supply chain would be fine and we are dealing with multiple industries and multiple products supply chain management it's quite wide range of products sometimes foods sometimes some kind of materials sometimes pharmaceuticals Yeah, the pharmaceutical one is really interesting now I think why don't I ask Hiroki next for his take on Sir, what do you think are the most impactful use cases out there and perhaps the one you've touched the most? Well, as Toshia-san said that I also think that the cross-intercity use case that would be the well, after people are thinking the same way you know of course at Fujitsu have been starting with the healthcare area distributing the medicines to the doctors then for that reason we use the hyperlature technology but if you think about the inside of the technology or the use cases that is actually the kind of supply chain model we just pick up the medicine but we can change to another good so that the same kind of idea is applicable to the other industries Yeah, it strikes me every industry has a supply chain of one form or another even say music and film there's a supply chain from the raw materials to the finished product so I do think it has the potential to transform every possible industry Makoto, Shirai-san what use case gets you the most excited that you've seen recently and special bonus points if you can say something other than supply chain Yes, I would like to share the finance area so the securities post trade as you may know so 24 companies joined this trial still in the POC so banks, dealers and investors and security companies joined after trade the stock and a lot of paperwork and confirmation by email is running now to apply the supply chain so to the operation efficiency so we are doing the POC and the POC is successfully done and the result was summarized and disclosed as a report on the website you can see the information in Japanese also in English on the JPX Japan exchange homepage who are some of the other partners in that project and the IT vendor any single IT vendor but like any banks or Yes, yes, of course but to move forward we need some collaboration partner that's a challenge when all three of you have started these projects with your customers on these projects what have been the biggest barriers to adoption of blockchain technology on the enterprise is it technological, is it the challenges of governance in these types of initiatives what would you say have been the biggest barriers why don't I start technically we are good not so much issues but the operation and system maintenance system operation who are going to manage the ledger who are going to own the consensus building part such kind of things the role model we are struggling to define the role model so maybe Fujitsu-san and Hitachi-san may know some good use case if you have some I want to know the best practice for delivery and operations so the challenges are operations woven into that is the sustainability model for these networks and the business operation Toshiya, have you seen some positive moves that help make that less of an issue actually to bring up some kind of convenience for some multiple companies sometimes we have so many stakeholders and as Makoto said consensus building is so hard they have different interests they have different intentions it takes so much time to get into the agreement among the stakeholders the time is passing and we cannot get any money it's not the business it's going to be tough for us to get into the consensus building and the agreement among the stakeholders it's a business issue we are facing such difficulties always one challenge in this domain especially when you call yourself an enterprise technology in the United States you think of an aircraft carrier or you think of that ship from Star Trek and both of these seem like massive if you are a software developer on a laptop you don't know where to start you can always do a hello world demo or a proof of concept but where do you start creating value without having to bring half an industry together on to one network have any of the three of you a proof of concept and a pilot starting to create some small scale value that then can grow we also have been struggling with the same program but again we realize that we must propose something else meaning that if a company or enterprise that means that the company is handling a certain product or information let's assume that Bitcoin is managing the money itself so if you think about some token if you buy something you get a token you are managing a token itself in the blockchain networks but then people or customers think that do we need to develop a token system with blockchain technology it might be possible to develop using the database itself then the customers thinking that do we need to invest those projects then our idea is why don't you connect that token networks and let's say the Bitcoin network together then you can exchange the value between among those networks then each of the network or the business has got another value so that's sort of the proposal we would like to start using the interoperability technologies so I would like to ask anybody who has a question for the panel to submit a question in the Q&A box here and we will try to leave some time before the end of the hour to get at least one of those so please vote, perhaps look at others and consider voting them up that sort of thing but we still have about 13 minutes here and how the government specifically the Japanese government views blockchain technology from a regulations point of view or from a infrastructure point of view what have you seen any of the three of you perhaps I'll start with Makoto if anything have you seen anything from the Japanese government that you've seen either as very positive about the engagement with the blockchain community I think yet to start it they talk about the blockchain but still yet to be decided so Japan created some new ministry digital ministry and the government decided to for example the Hanko culture changed to some digital so to do this I think we this is blockchain's good technology for the future to identify and also to some company and individual that we are proposing now but yet to be said they are open to it but still very tentative about it Hiroki have you seen Fujitsu currently the government is more focusing on the COVID-19 stuff but I know that some activity especially in the financial agency they are very keen to the new technology because the fintech technology is very hot so that they are also interested in the blockchain technology as well but because of COVID-19 the activity is somehow slowing down I do think that they are somehow to try to using that technology into the the financial area what we've seen in the United States has been that some parts of the US government and sometimes even local states do see opportunities to use blockchain and distributed ledgers to implement regulations and to help manage markets in a way that makes them automatically conform to regulations from a reporting requirements point of view we've seen very active projects in the insurance industry on this front the insurance regulators are very keen to use it and I believe it was Hiroki who mentioned the pharmaceutical supply chain there is a regulation coming in the United States which requires all sorts of reporting of provenance to pharmaceuticals throughout the supply chain that was intended to be adopted or finalized until 2023 but it is being pressed into service now for tracking the distribution of vaccine credentials and everyone is looking to this technology as an underpinning for doing that in a fair and auditable way so some really exciting things happening there Toshiya have you seen anything around government involvement the Japanese government or even beyond that you've seen as very positive and supportive of the blockchain space it's not a government but the central bank Bank of Japan showed their intention to deal with the CBDC central bank digital currency it's going to be quite possible for them to utilize the blockchain technology for that purpose but you know it is not clear that whether they will use the blockchain technology or not but it's quite possible and it's quite promising for us to deal with the blockchain technology like hyper-leisure fabric or hyper-leisure bezel or whatever so it's going to be quite interesting maybe they will have a POC starting next April or spring time and it's going to be quite interesting to see what's going on I'll open this question to all of you and just say the first thing that comes to mind really what do you think are the one or two things that the hyper-leisure community really must do before in 2021 to accelerate adoption of blockchain technology especially by the economy and the industry in Japan or even globally who wants to take that first okay and you know it is quite important to expand the adoption of the hyper-leisure technology is to let people understand what's going on and what is the most promising use cases so sharing the information about the successful stories of the hyper-leisure technology the members or the community members maybe should distribute such kind of information more aggressively and to let people understand the power of the adoption technology that's my thought let me just know briefly it seems like people are not able to throw the questions over the Q&A button oh wow okay I have seen some questions show up in chat on the channel, on the chat if anyone has any questions on the chat not Q&A I'll go to those next I was thinking that might be happening and I just saw the chat so I appreciate that let me finish off that round though it sounds like we have Toshia's perspective Makoto or Hiroki, do you have anything to add? Well this might be a very small thing but we as a cactus project looking for some contributor because we have just started so that more development people are joining the project I couldn't agree more definitely if any of you are developers this is a project that can help make you famous there's always room for work to be done always room for new contributors to come in and we will reward you with a lot of attention if you're able to come in and make some good contributions and hopefully we'll have some opportunities to get your name out there as well if that matters to you but we could also use any help that we could take Makoto, do you have any thoughts on the topic? Yeah, as I said before so the best practice and very successful use case and role model we need so if you share with us we'll be helpful Okay, great there's a question in chat we'll take the remaining four minutes how do we measure the impact we're having I'll notice the questioner you said how might we evaluate it's how popular it is compared to the Google Trends and I should note Ethereum being a public cryptocurrency has a lot of people talking about it all the time because they own tokens so I have to say this is not quite apples to apples so to speak and even Korda as a word Korda is not quite as unique as hyper ledger is but I think it's important to look at the market how do you understand the weight that hyper ledger carries or the opportunities that we have to grow more or where we should be and we aren't how do you think about our position compared to the competition competition feels so weird in an open source sense we want everybody to be part of hyper ledger so I ask a really long complex question and then I throw to some of the I apologize for putting you on the spot it's really difficult to say well if a customer asked you for a recommendation do you base that on kind of the technical differences or do you kind of say one of them kind of always seems to work best or a customer is coming to you and saying we want to build it on fabric, we want to build it on Ethereum and you kind of go okay here's how we'll make that work well simply we are contributing more more on the fabric base that you know we think that personally we believe that we need to set the public more meaning that the hyper ledger anyway so I don't say any differences between the others you know Toshia or Makoto I would say that you know hyper ledger is good at something and the coder is good at something else but Ethereum is good at something different and you know so maybe it's going to be a combination of the multiple technologies or multiple frameworks in a quite near future and you know but in terms of the implementation I would use the information like a Forbes 50 blockchain 50 and it's a media information and you know hyper ledger is maybe the implementation is the hyper ledger based right so the market itself is recognizing that the hyper ledger is key technology key blockchain technology and I would utilize such kind of information so not the not only Google trends but the mass media information so marketing committee is gathering such kind of information at the hyper ledger and you know you should use such kind of information so much that's what I believe Great and Makoto any final thoughts on this as we wrap up the panel I'm sorry I don't have any green answer about that One of the hardest things I think for us to get across is that hyper ledger is this family of technologies right that fabric has been developed and I think through the Forbes blockchain 50 survey you can see is one of the most widely deployed perhaps the most widely deployed framework out there but I think the real strength of their approach comes from the diversity of different options they're very much like databases right you have my SQL and MongoDB and you know all sorts of different kinds of databases out there even though they all store data and allow you to query data so that's what we're about to hear Iroha is a very important option as well it has been used for a number of interesting projects and there's a lot I think for the other projects to learn from how Iroha is built and managed and the user base out there so we're really proud and and really appreciative of all the support that the Japanese community has given to the hyper ledger project and we hope it's returned in impact and hopefully profit for all of you and profit for others on the call when you decide to use this in your projects so thank you very much Makoto Hiroki Toshia thank you as well to Hitachi Fujitsu and NEC for your support as organizations of hyper ledger and now at this point I'd like to turn it back over to Nori to carry us into the next segment thank you all very much Thank you Brian and the panelists thank you so much Thank you very much The next session is actually in Japanese language although the slides will be in English but the talk will be in Japanese so the speaker is Jin Watanabe from Entity Entity Data and he will be talking about the challenge of applying blockchain to enterprise systems in entity data Thank you Thank you for your introduction. This is the news section of NTTdata. My name is Watanabe Jin. Nice to meet you. Before we start, I'd like to talk about NTTdata and blockchain. I'd like to introduce about two or three slides. I'd like to talk about NTTdata. I'd like to talk about NTTdata. This is NTTdata, which is located in Kotoku, Tokyo, Japan. It's a group of people who work as SIRs. All of them work together. There are 50 locations in the overseas area. I'm a member of NTTdata Blockchain COE. We work together as a blockchain team in the overseas area. The key word is unity in diversity. We're thinking about blockchain technology. We don't want to focus on one thing, but we want to choose a wide range of locations. We're working on a red-brown laser pointer. We're trying to find a variety of areas, and we're looking into that. Maybe we're going to use the Internet and evaluate it, but it's a bit different. We're going to focus on Bitcoin, Ethereum, and Hilary. We're looking at the haparaja fabric. We're looking for projects that offer So, I'm also looking into the depth of that area. Yes. So, I'm especially interested in the ability of the Appleta Fabric, and at this point, there have been a lot of calls as well. This is also a simple project introduction. I'm currently working on a representative project. There are some things that can be named, for example, as a theme, I would like to create a business cooperation cost, and also create something new. I think the project will be divided into two themes. I think the whole project will be divided into two themes. At the time when I was trying to create a business cost, I released a new series about October. There is a project called Trader Astute. This is a platform to circulate the information on the paper of the defense station. You can also use the information as a keyboard reader. The main target is the information on the defense station, the defense station or the workstation. It is a story about the use of paper, paper, and paper in the system, and the use of blockchain. In addition, there is also an overseas JMA. There is a project called Spunta Project in Italy. This is a product that was applied to the commercialization of the bank. This is also a product that has already been used. In addition, there are things related to traceability. On the other hand, it is also a story about creating a new value. This is not a specific use case, but it creates a number of consortiums. In this way, there are several ways to find a use case that can be applied from now on. There are stories and rack chains. This is the main topic from now on. This is the blockchain and enterprise system. In my opinion, I would like to introduce the theme of what I was thinking about when I was actually going to enter the enterprise. First of all, as a small-scale energy challenge, I was thinking about how to use data before thinking about the function. I was looking forward to seeing how we can do the same thing with ordinary RDB. In particular, I wanted to preserve access control and a lot of data, especially about access control. I think it's quite difficult to understand, but at the time when I was working on the blockchain, there was something like, it's not all the same. So I was looking for a way to respond to that. I was also thinking about how to think about information providers and points. Specifically, this is something that I used to cooperate with the NTT data company, rather than the NTT company. But I had to think about how to make a data management mechanism. This is the name of the block trust DMP. I just put the data in the blockchain. I was thinking about how to use IPFS and other data sources as a basic data management mechanism. As for what I'm working on right now, I'm going to use the blockchain, the HyperDubblich 1.4 and 2.2. That's right. The data source, the meta-data block chain, all the other information, the hash, the block chain, that's what I was thinking. So I was thinking about how to use the IPFS and other data sources. I was also thinking about how to use the controllers and see if you can see this information from the user or if you can't see this information. That's what I was thinking. That's all for the DMP. From here, I'm going to talk about what I was thinking about. When I think about enterprise, I don't think it's bad if you have a real-time experience. It's a long-term experience that I've been working on for a long time. What I really need is availability, availability, wind flow, of course as well as maintainance and monitoring. I don't think it's completely out of-chain as well as our network. I might explain lots of different things but using one source on-praise like CloudDev, that's what I'm focused on. I was thinking about that as well. That's right. That's all about evaluation and technology. That's where I started working. At first, I was thinking about what's different about Pock and Production, but in the end, Pock is just a proof of concept. Production is... I don't know how to say it, but I was thinking about what's going to be produced, and what's going to be a new value. As an enterprise, we need to make sure that the value is maximized. I was thinking about what I could do for that. I was thinking about the capacity, performance, and so on. In this slide, I focused on the Infra-area instead of the Business-area. Let's take a closer look. For example, the Maximizer-Value, what we can, is here. Production is... In Japanese, there's a special requirement grade, so I'd like to talk about it in detail. For the requirement grade, if you take a look at the page, it says Non-Functional Requirement Grade. In this slide, I'm going to take a look at the operational ability. In the long term, it may be called operational maintenance ability, but this time, I'm going to take a look at the operational ability. Then, the operational ability, and the operational and operational ability. Then, the security. Then, the performance and performance and so on. In the long term, I'm going to take a look at this slide. Yes. Of course, it's all important, but in this session, I'd like to focus on the operational ability and talk about it. For the operational ability, in other words, the ability to keep the system green, to keep the system clean, I think it's a great opportunity. This slide is also a lot of things that are important for the requirement grade, but this time, I'm going to take a look at the daily maintenance of the system, and the support of the system. I'm going to talk about the maintenance of the system, and the support of the system. I'm going to talk about the operational ability. In general, the daily operation is the same, but the way to do it is monitoring, loading, and the backup of the system. I'm going to take a look at this slide. On the other hand, the support of the system is related to the incident handling and the trouble shooting. Yes. First, I'm going to take a look at the daily operation, and the monitoring, loading, and the support of the system. Yes. In general, I'm going to talk about the project, and I'm going to talk about the problem of the system, and the support of the system. First, I'm going to talk about the log pattern. In the POP, it's not a simple process, but it's a process that we have to think about until three years later. In that case, there will be an upgrade on the way, and not only in-flat, but also on the application, and on the application, there will be an upgrade. So I'm careful not to change the log pattern, or the size of the log, or the size of the log. In the case of the log, it may not be the same as AWS, but I'm careful not to change the upgrade after the log collection. This is the only blockchain product, and it's not limited to the blockchain, but I've been working on POP for a while, but I don't have much experience with it, so I'm aware of it. Next is Job Scheduler, and what I'm talking about is, in a few projects, I've forgotten the name of the product, but I don't have to include the Job Scheduler agent, and in the daily backup, there are a lot of things that need to be considered, so I'm thinking about that. As for the specific terrain, the blockchain system, and the report bound for the agent, are pretty much the same, and if it didn't work out well, it might have been a bit of a mess, but that's what happened. It's the same, but as for the project conflict, I think there's an appearance policy for the customer, so when you're on the side of the existing system, there should be an appearance policy, so I think you should check it out and see if it works. That's what happened. As for the customer, in the security policy, for example, if you have to include all of the virus types, you should include the virus types of software. For example, if you don't have to include an ordinary orderer or PR, if you don't have to, it might be a bit of a mess, but at least you should include all of the PR, but when you're on the side of the market, you don't have to think about it when you're on the side of the market. If you're an enterprise, you have to think about it. For example, if you don't have anything in the company, the security team will get angry and you have to include it. At that time, the system test was that while the Antivirus agent was moving, it was easy to see whether or not the lead and light performance was quite low. Of course, it's not limited to the blockchain, but especially in our team, the blockchain and the lead light performance were correct. In terms of IPFS, if you have a place to write a database, please take it out from the beginning. But it wasn't very detailed, and there was a place where the performance was down. There was a place like that. Willis monitoring, that's right. That's where it is. I've experienced it around the time. In terms of performance, it's performance, but it wasn't 100% accurate. And back-up. Back-up, I've written a list, but the system probably won't break, I feel. For example, Audair's project crashed all of a sudden. It was a system test on the list, and it was a day before when I had to do a sample test on the list, but when it crashed, it broke the left index. So I think I'll probably do the same. At that time, I had to add a new model, but in the end, I had to think of a normal way of doing recovery. This may be good, but back-up doesn't mean there's no way of recovery. I think that's right. Especially, new OSS, of course, but there might be things that we didn't do well. In that case, I didn't think there would be any, but I thought there would be, so I had to think of other ways of doing recovery. That was the point. Next, I'll talk about support. This might be maintenance-easy architecture, I thought. First, in the technical part, I used reference architecture this time, but I used Kubernetes. However, in the business unit of some regions, there's no one who can use it. It's a non-resource, and it costs a lot of money, and it's expensive for the members. That's what I did. I removed the Kubernetes and used it somewhere else. There's a new technology based on blockchain, and I have a technology button, so I want to use it. It's useful, but in the business unit, when you're trying to make a profit, I don't think there's any way to do it. Of course, if it's a reasonable project, I think the members can use it properly and use it for single-use. That's what I thought. And open source support. I've lost my words, but in my company, there's a part that looks like a good support, but there's no merit in making a profit. For example, the IPFS and the blockchain technologies are not in the OSG team. In fact, when it comes to the business unit, when it comes to the business unit, it's hard to keep the skillful OSGS engineer. For example, when it comes to trouble shooting, when it comes to the business unit, it's hard to keep the skillful OSGS engineer. And in our team, in the entity data, we're trying to make a profit as a pool. We're making a profit. That's it. That's the end of my main project. I'm thinking about what we should do in the future. What I was thinking was that we should connect the multiple companies and the multiple organizations. That's what I'm talking about. There's a lot of information about the business unit. I'm thinking about what we should do and the protocol. I'm thinking about whether or not we must be able to explain the general standard for the company. And there's a bit of the difference now. Not just the blockchain, I'm also thinking about what we can do with the blockchain. I'm already thinking about what's already lacking in the application, so I'm thinking about Last but not least, I'd like to add something to this. In terms of the existing Applite Enterprise, if you connect something, you can understand that blockchain is useful, but I think you have to keep talking about what you should use. 最後になりましたからはパラジャー5周年おめでとうございます ありがとうございました あの Thank you so much Watanabe-san それでは本日最後のセッションに入らせていただきます 本日最後のスピーカーは 以前も何度かこのHyper Ledger Tokio Meetupで I'm Takemiya Makoto, and I'm the CEO of Solamitsu. I'm a project called Iroha, and I'm the one who created Iroha. Today, I'm going to talk about the story of Iroha. The next speaker is Makoto Takemiya. He is the creator of Hiperreja Iroha, and he will be talking about Hiperreja Iroha itself, as he will be talking about Cambodia Central Bank. So, Takemiya-san, please welcome Takemiya-san. I'm a little shy, so can you see it? Yes, you can see it. I will speak in Japanese today, but the slides are in English, so please feel free to also ask questions in English if you'd like. Today's Iroha is all in English, so please watch it. I don't think it's necessary to introduce myself, but I'm Takemiya Makoto, the CEO of Solamitsu, and I'm the CEO of Ken Group. Hiperreja Iroha has been active for about 5 years, but it was established in 2016, and it has been active in several countries. Just 4 years ago, before 3 months, Hiperreja Iroha was officially recommended to the Technical Stealing Committee. With that, the company of the military and the Israeli company called Japan's HITACHI and Entity Data-san, we had a meeting in Tokyo, and about 4 years ago, we officially became incubators. After that, about 3 and a half years later, we were able to use it in real time. We have also developed several applications and companies using Hiperreja Iroha, but among them, we would like to talk about the project called Backon, which is mainly done with the Chinese bank in Cambodia. After that, I would like to talk a little about the future development of Hiperreja 2.0, which we are currently developing. In terms of the Chinese bank itself, I think many people are talking about it and many countries are also considering it. Currently, the countries that actually operate are only Cambodia and Bahama. Other than that, China, of course, is doing the pilot of the Chinese digital currency, but the block chain is currently using Bahama and Cambodia, which is the best example. The project called Backon, which has a number of companies, is a retail system that can be used for anyone with just a phone number. What the block chain is holding is that it is the first rate in the world. Currently, there are hundreds of thousands of users, and 18 companies are participating in the system. The Chinese bank doesn't have a lot of retail, but this is an impressive thing. The mobile app is also provided and if the user has a Cambodian phone number, the Chinese phone number can be used to complete the decision in a few seconds. As a result, the Cambodian Chinese bank has been working on the block chain system and the company has been operating since 2017. After that, last July, the pilot that anyone can participate in started, and this October 28th, the White Paper was launched. There are a lot of details, so I think you can also participate in the White Paper. There are a lot of features of the system, but using Il-Hao, the Bank of China has the Finality system, and the block chain of Il-Hao has all the nodes, the Chinese bank, and the private bank bank is participating in the API business. This may be better, but the private bank runs the gateway, and the mobile app sets up the payment gateway, and the decision can be made. Of course, not only the mobile app, but also the desktop app is also set up. For compliance, the price of the block chain is about 250 dollars a day, and it's a system aimed at the private bank where you can actually go to the bank and do a lot of special KYC, and you can get these conditions. There are a lot of articles written in this system, but I think it was published several times in Japanese newspapers. These systems are, well, well, of course, the Chinese bank runs all the nodes, so all the database can be used without any use. However, all the funds and customers can participate in this, and the decision-making architecture will be easier. With that, the new application design can be developed very easily, and the trust will also rise. In other words, with all the mobile apps and desktop apps, the secret key is the user's personal device, and all the transactions are displayed in the user's device, and then thrown into the network. In the first place, there is no money, so it is very difficult to make money. For example, if you want to make a lot of money, you need to use all the user's device to make money. I think it is easy to understand the need for money. In Cambodia, there are very few people who have money. Currently, about 2% of adults only have money. In Cambodia, there are very few people who have money. In the big cities, there are people who go to work abroad, and they spend a lot of money. In Cambodia, there are very few apps. They just spend the money by booths, and then send SMS. The service doesn't realize that internet service is bad. Backvacom can improve the number of friends. about 1% of the GDP is available. So, for example, in Cambodia, it is available for about 1 billion yen a day. For example, you can save money, for example, you can live in Malaysia, and then save money to your family. So, you can save money easily. It is very easy to save money. I don't have many people here. Especially for women, it is difficult to access the money. So, you can easily use the back home system. You can save money anywhere you want. For example, when you work in a station, you can save money to go to school or to the hospital. You can see that. You can save money directly to the hospital. So, you can become a better society. Cambodia doesn't have a lot of digital resources. So, there are very few countries with digital resources. So, when the digital resources are collected, more people will be able to create new services. The question is often asked about digital resources. According to the design of the back home system, there is almost no effect on the digital resources. The reason is that the money from the back home system starts from the cash. So, the digital resources from the back home system are all connected to the cash. So, the same as the cash, you can get the money from the back home system. So, you can decide on the amount of money you want.  So, the number of dollars you want is about 20 million. So, the amount of money that you want is about 20 million. Well, basically, for example, in a place like Suika or Eddy or something like that, I think that the customers are very expensive, and they charge their own courses. And then they go to the convenience store, buy a tea, and then send me a message. But the fact that the actual money comes into the store takes a little time, and the price is also high, so the price of the store is relatively high. With a system like this, the customers first take the energy and give it to a company that supports them. And then they take the money from the back-con. And then, when they decide, the decision is completed just by investing in it. Well, the president is running the money, so the decision-making finality is accepted, so if the store is charged with this kind of back-con, then you can use it already. You can use it for cash, and you can use it for other decisions. Well, you don't need credit or anything like that. All of that is done by the block chain of Hyper-Edge Ilha, and you can use it for instant payments. Well, I think the same system can be applied to other countries, but basically, the structure is the same, and the block chain core system can be applied to other countries. So, in particular, Hyper-Edge Ilha has a system that is easy to manage with digital identity. All of these structures are easy to put in metadata, so it is a system that is easy to use with verifiable claims and digital identifiers. So, if the money is invested in the U.T.O.D., it will be very easy to use these systems, and it can be applied to other countries as well. Well, the same system can be applied to several apps, for example, the old screen is a bit slow, but the system called BIACCO is based in Fukushima Prefecture, in Aizu Wakamatsu City, and the system called GAKUNAI TSUKA has been applied since April this year. So, it is the same system as the BIACCO system, so this system uses Hyper-Edge Ilha to build a mobile app on it. Well, Hyper-Edge Ilha is a system that is easy to use with the U.T.O.D. because the core command is provided, and the U.T.O.D. has a system that is easy to use with the U.T.O.D. It has a very simple data model, and the domain is like a box, so you can have two assets and accounts in the domain. Now, in order to recognize security, there are a number of signatures, which means that the multi-signatory is very easy to use. Well, in terms of Hyper-Edge Ilha, there are commands like this, for example, if you make a Brian coin, you can create an asset command, and you can add a Brian coin and a row, and then you can create a new asset. So, if you import these coins to the north, you can create a transfer asset command and then you can transfer it to another asset. It's a very simple logic, but it has a lot of permissions and details, so you can create a very complicated system. Ilha has a branch-type permission model, and it has a lot of details, but for example, for all commands, you can set who can execute these commands. For example, you can use the permission of a coin or a token to transfer the third asset. You can grant permission, and you can create a complicated system. Before we talk about version 2, Ilha has recently released a new release. This is Ilha's GitHub page, and Ilha 1.2 has just been released a month ago. This is the latest release. This has a lot of features, so for example, if you don't know about Hyperledger Ulsa, this is a library with a high-pressure project, so it has a lot of trust. It uses Ulsa from 1.2. It also supports multi-hash, and the very interesting thing is that the integration of Hyperledger Bolo is also possible. If Ilha's commands are not enough, you can develop smart contracts and execute them. There are a lot of details. That's very important. Other than that, there are a lot of speed improvements and various improvements, so if you are interested, please take a look. Basically, Ilha is an open source, so we have all the information about development on Hyperledger Wiki. For Israel's sake, if you would like to experience it, you can start with the Hyperledger Wiki from the Wiki page of Hyperledger Ilha. All of the chat is connected via the web browser, so even if you go back to Israel's chat, you can transfer it to everyone. There are a lot of issues for beginners, so please take a look. In the first minute, Ilha is currently developing a new version of Ilha 2.0, so I would like to explain about it. The link is a bit slow, but it's in Docs. The Hyperledger Ilha 2.0 is a time when you can see Ilha 2.0. In Docs, there is white paper, so if you look at it, there are a lot of things about design. The details are written, so please take a look. The feature of Ilha 2.0 is that Ilha 2.0 wasn't a totally smart contract, but Ilha 2.0 has event triggers, and when the training is complete, it will be able to perform. It will be able to perform the function of all the movie concepts. Now, the speed is improving a lot. The database is on memory, so the speed is very fast. Ilha 2.0 is written in C++, but Ilha 2.0 is written in Rust, so if you are interested, please look forward to it. It's a bit long, but it's over. Thank you for your question. There is a question in the chat. What happens if the device in the secret key is broken or the secret key is lost? Will you answer it? That's a good question. Especially in Cambodia, if anyone can use it, the device will definitely be lost as usual. In that case, I will use the 1.0 permission to exchange my secret key with the add signatory and remove signatory. There is a command that allows you to exchange the key. I will grant this permission to the private bank that has been stolen from me. If my device is lost, I will go to the bank and show my secret signatory. I will exchange my key. However, if you don't get full KYC, if you don't get full KYC, if you don't get full KYC, if you don't get full KYC, if you don't get full KYC, any other questions for English speakers? You are also able to ask questions in English. I have another question. I know that you have a question. Do you have any other technology aspects for IoT? What do you use on this? Well, I think the thing about IoT is that it's probably developed on C++, so even if you work hard on an embedded system, there are times when you can't do it. I think the question is whether you should use blockchain on your device. Well, I think it's possible.  If you want to record only data information, it's very easy to record. If you don't have any questions, we'll end your session here. Thank you very much. Thank you very much. Thank you. Well, that's it for today's session. This time, it's Hyperledger's 5th anniversary anniversary, so we're going to hold it in a different format than usual. Thank you very much. It's been more than 50 years since Hyperledger, but I think it's going to be more interesting from now on. I'd like to ask everyone who's been working on Hyperledger's project for a long time to come. If you still want to work on Hyperledger in the future, if you're in such a situation, please work on Hyperledger more. I think it would be nice if you could actually work on it and contribute to the project, because there are various projects such as Fabric, Ilha, and Kaktas. I think it would be nice if you could actually work on it and contribute to it. I think it would be nice if Hyperledger's products and services were available in Japan. Thank you very much for the 5th anniversary. Thank you very much for the 5th anniversary. Thank you very much for the 5th anniversary. For English speakers, we are wrapping up the session now. This has been the 50th anniversary type of the meetup, but it has been wonderful 5 years. I hope everyone will stick around with Hyperledger project from now on as well. Thank you so much for joining. I hope you will have a wonderful holiday season. Bye-bye.
