 So I'm Hart Montgomery and I work for the Linux Foundation where I serve as the CTO of the Hyperledger Foundation and today I think we have a really exciting discussion planned for decentralized technologies. So how this is going to go is we have two fantastic industry players in the space, Shingo Fujimoto from Fujitsu and Tomoko Kondo from Softbank and they are going to present a little bit about what they've done with their respective companies in decentralized technologies and then I'm going to ask them a bunch of hard questions and I hope you all can join in. So we want this to be as interactive as possible so please if you have a question at any point feel free to raise your hand and ask and we'll try to get you a microphone. So fantastic and I will hand it over to Shingo to start. Thank you Hart-san for the introduction. So my name is Shingo Fujimoto of the Senior Research Director of the Fujitsu. So we'd like to have a short presentation to align to the knowledge level for the audience and we would like to share to the floor with the further discussion and questions. So my title of the slide will be a dirty into working with the connection chains that was Fujitsu product using to the hypervisor cacti as an infrastructure. So first of all I would like to start with the question to you for what makes the money in the blockchain world right now is kind of virtual currencies and NFT will be a very short term for the ecosystems. So we would like to have improved the structure while the business model will be a more long-term or sustainable way for that which has to be a circulate to some of the players inside. So in that case this is the kind of target area for businesses we are going to. So the friend we are talking about such a thing because of the nature of the blockchain is a pretty simple that it only managed to the very limited digital assets. So the fact we thought was how we can be in large to the such ecosystem as circulate to circulate we need to be combined to the much block chain into the one. So that was a kind of combination of the order. This is a similar model of the mashup of the web technologies. And we are mashup of the block chains are the concept of the design of the services. So the friend we are talking about the other in my shopping to the such a blockchain had two different issues. One for the transparency and one for the much phase transactions. For the case of the transparency because the blockchain is a kind of parking is always needed for the governance purposes. And the second one is issuing is a much phase transaction because of the most of the businesses had not a single shot. It has to be taken several phases to complete. So the here's the reason to using to the open source. So the because of the blockchain had a multiple choice at this moment. We hyper leisure provide to the multiple blockchain. The solution here on the top at least the five blockchain and the platforms are available with without any fee to use. So the the however to the that is a little bit difficult to the to mash up those in directly because of the there is some sort of the difference of the protocol and the characteristics. The difference. So the the cacti here is a one of the two of the hyper leisure product and now the graduated from the other product ready and the cacti will provide to the some sort of the high level abstraction of the the blockchain networks. So the here's the best short explanation about the cacti as a project. The cacti will provide to the multiple plugins those are the for example that we can be proud for the israel and the fabric for the other combination targets. So that is the same for the corridor or other platform can be any combination can be the probable for the cacti nodes. The cacti node is the vendor specific implementation so that we can be the enjoy their their their all the combat combinations and additional in addition we can be multiple blockchain in the same time like our three or four blockchain can be integrated into the one. So this is a typical use case where it was introduced as a demo application on the GitHub. So the other friend we are thinking about to the three in blockchain technology record in the for the D. I. D. and distributed identity. Go Israel for the stable coins and the fabric could be for the case the car the lock unlocking locking system will be here. So it is assumption so the the indie will be providing to the check of the the employment of the my company for example so the but the my employment the certificate will be endured the privacy with zero knowledge proof for the case of the after the that's check at the discount rate was applied by the smart contract and that the price will be set to the goal is very much at the target of the transfer digital assets and the friend that's at the digital asset was safely or successfully settled the car will be unlocked for the other let's say the one hour from the moment and after that he returned to the car and the the remaining the price will be a cash back to the client. So these are the kind of the the multiple scenario is possible for the using to the cocktail. So that is the meaning of the combination of the web to word for the left hand side and right hand side will be web three because the people think that web three is good enough or worse to use however it is there is some sort of the hard of there. So the one the the we are simply saying to the such a concept so the we are using to the heavily for the hyper as a cocktail as our own product and the connection chain will be extended for the part of the such a business logic part is also implemented as a smart contract the different way. So the what we did is the the smart contract will be executed to the such a scenario as a platform level and all the record will be remained on the blockchain on that was currently implemented on the hyper as a fabric. So this is a cure code for the technical detail but this is a kind of the commercial time. So I would like to share to you here we are using to the best on the such a knowledge that we are providing to the mud to use cases today. One for the financial area like a cross border bond settlement park with Asian developing bank. So the good place was there are the instead of the changing everything we are trying to simulate or emulate the current existing transit financial transaction system like the the finance all the banks and government actually doing. So the in the right side hand side this is a model of the how we can be send them the foreign money to these foreign account. We will be we did not actually send out to the physically for the foreign currency other inside of the other mode system. There is a corresponding bank will be intermediate for those businesses and the intermediate bank accept to the local currency and the foreign currency will be send out from their account. So this kind of the mechanism will be easier to be acceptable for the even the cross border situations. So the other actually we did we implemented those we using to the much proven their solutions. We could connection chain provide to the other interworking for those the different vendors the solutions for example like a green box is implemented for the local country. The local country did the DBP settlements like at the friend the money was successfully paid the ownership of the digital security will be transferred and also the red hand side left hand side and red box one is sending to the foreign currency to the local currency as a combination of those. Those red and green boxes seamlessly that is that we are going to the cross border DBP will be a theory possible. So we actually built to the those patterns for the suit with three vendors. The ceramic consensus and the R3 provided those red and green box pairs for the other part of the partner in the environment. The second we had the use cases here. We were well as showing to the possibility of the how the mashup blockchain could be work because of the many people talking about the CO2 offset reducing to the CO2 emission is always the problem or social problem. However, to the those work will be usually built on the private network because of the they had some sort of the private corporate secrets maybe so the other instead of the unified to the those blockchain into the simple one that we are proposing to the intermediate by the for the case of the other. They need to be here how we can be guaranteed their source of the other such as CO2 offset other effort of the each companies. And once it was tokenized that tokenized the value will be reflect to the another local block chance. However, to the we need to be guaranteed the consistency with the with multiple players in the same country or even the old world that kind of the model need to be the blockchain interwork is needed. So the model was we provided was in the center that we had a common place to be creating to the CO2 offset and exchange and applies. Those are the in the center in the middle of the blockchain is only shared with a multiple block chance, but each blockchain was built by private. That was a model of the proposal. So by the way, the those those are very short example for the possibility of the mashup of the block chance. So the end Fujitsu now provide to the you're the test bet or a playground for the how we can be mashup to the technologies as shown. So the other please the technician for the work graph and the QR code guide you to the demonstration site. That's my the end of my part of the presentation. Thank you. Yeah, so I make an effort to expand the Linux foundation technology. So and I want to make the use case on hyper laser. Thank you. So and today I want to introduce using private blockchain academic data sharing platform. This use case is the first use case for Softbank. Okay. So expectations for use cases in any community where ensuring high security and controlling authentication is a private space and necessary private block chains provide to be highly useful. While we have conducted verification through hyper laser successful from the perspective we anticipate we anticipate that a blockchain based authentication infrastructure for academic information in university would be a very appropriate use case. Concerning academic data in universities there is a desire to make it public. But there is also a risk of leakage balancing the desire to share and involve knowledge with a concern for the risk of leakage process challenges. We believe that blockchain is suitable for addressing the following requirements crucial for resource resolution in a smart way. First, it should be possible to limit the authentication scope for each case of condition. Second, the tracing of access behavior history should be reliable. We will supply this use case by using hyper laser fabric and hyper laser indie. And in future, I want to use a kakutai because each of the university has their different data structure. So I want to connect different blockchain style. Currently, the formation of community comprising active university and student and alumni is sought after in many universities. A company want to laboratory with university student. University student want to challenge the laboratory of company. But we have to protect the data so I want to use hyper laser. So let's introduce issue related to sharing papers. About provider, persons for sharing. I want to researchers working on the same theme to utilize my research findings. I want my results to be widely used in society. I want to know how useful my research is. I want to connect with researchers working on the same theme. Reason for hesitation of share. What if the content is understood without permission? What if it is shared with intended audiences? And about user. User, I want to connect with researchers working on the same theme. I want to know about previous instance of research of similar themes. Reason for hesitation of reference. I cannot evaluate the accuracy of the content. So now we consider about solution overview. I want to introduce three key features. First, user identify verification. Verify the credibility of researchers before sharing retouches by checking qualification information issued by universities. Research loves or participating project. Examples, researchers authenticated by the university or lab or collaboratives, researchers providing authentication. Second, record of starting activitments. Record retoucher registration, reference request, reference permission and reference history over leisure with data and time. So maybe we use hyper leisure fabric for this recording system. And we want to open the recording data to public. So all people check the recording and they get the information. And third, difference of, third, deterrence of unauthorized sharing. Users can report any identified unauthorized use to certifiers. Maintain a state of third party verifiability using the recorded history of sharing achievements. Certifiers have the authority to revoke the authentication of researchers engaged in unauthorized use. Maybe when we start to POC, we have many troubles and we have to consider all error solution. So now I think three points. But if you advise for us, more key point, please advise. So an image of credential for sharing documents, please the diagram. So each of certifier and researcher has several credentials. So for example, digital ID and graduate qualification and authorship of document A. And your qualification of document A and so on. So each of researcher and certifier has several credentials. So and we can check the combination of credentials. This diagram document sharing use case overview. Researcher A registered document A for sharing purposes. And researcher A, registration to document DB, literature A, and we use hash value. So we need not the contents of document. We only record hash value. And we will make the hash value by using the old contents of sentence. So and I think we keep the security. So and registration to document DB return to researcher A, ownership of document A. And literature A send search for document A and become interested. Literature overview public and literature as DID. And if researcher B, B is interested in the researcher A's document. Researcher B request the researcher B check the racial record and researcher B applies for reference to document A. So and researcher B's request accept by researcher A. So and begin to research B access to document A. So and of course we get the recording for accessing from literature B. So and researcher B obtained document and researcher B registered document B created by referring to document A. And literature B, hash B and hash A recording a legacy record. So this is basic mechanism. So and next January we begin to POC at Japanese University. So and first step we check the basic system. And a second step maybe we start to next May. So and I want to try to use a kakutai. So please help me. So thank you so much. My presentation is all I have to learn English. So thank you so much. But I'll ask a general question to start. So to both of you, why do you think enterprises have become more and more interested in decentralization in recent years? And what are some of the sort of broader, larger benefits it brings them? Yeah, can I start from there? As a part of my presentation, so the current public chain is not the mixer money for the businesses. So I think that we want to change the use of the blockchain for more practical or more related to with real businesses. So that is why the people are starting to using the enterprise blockchain because of such a non-cryptocurrency businesses are getting popular. That is my opinion. So about my opinion, there are huge data in the world. And now almost companies want to use huge data. But it is very difficult to correct huge data. So they begin to use data virtualization. So they channel to different data and they can make the original data catalog. And about authentication and the transitability, so all data belongs to each person. So I think it is very useful, a blockchain, a public blockchain and a private blockchain. Thank you. Wonderful. So I know you both talked a little bit about open source in your presentations. So I would like to ask again sort of, you know, what role is it that open source plays in your strategies for bringing decentralized technologies to market? And do you want to comment any more on any other open source technologies you use? I know obviously Fujitsu uses cat die, of course. Okay. Let's start with, well, the five we need to the blockchain as open source is a friend that I provided to use cases. Both of the case, we Fujitsu did not build our own leisure in technical. So those measures are built by the other vendors, like for the ADP case, security token review, managed by the different vendors. Also the money was also. So the such a situation in the legacy system, we need to be sign up to the NDA and we need to be start with how we need to be communicate to their from the beginning. However, we are using to the cacti as the interworking technologies that we can be say, here's are you are you need to be download the components. And there is a know the sign up thing so that you can be obtained your own code and run it. And we just need to be provided the IP address and the pod to be interwork. So that was a very fantastic thing. So I think that that was the most beneficial part of the vendors project. I think so. So and open source about open source. Several countries are engineer correct. So and the similar country has the many use case and data. So and we extended the idea and data structure and so on. So I think I believe we make the data structure distributed data structure and data authentication in common standard. Thank you. Wonderful. And now I guess I have an individual question for each of you. So Fujimaru San Fujitsu has obviously been involved in hyper ledger since the very beginning and has started and maintained the cacti project. So how does being at the forefront of this open source innovation and distributed ledger interoperability help to bring business and decentralized systems to Fujitsu. Yes, I think at the time of the starting of the hyper ledger foundation, there is a big debate to the why we need to be part of the open source community. Because it's free and there is no need to be participate. However, to the at the later on we figure out that it was wrong because of the open source technology is always comes from the needs or their will. So the what we think need to be if we are taking the lead of the some market of especially for the industry markets that we first of all we need to show to the what we thinking about using to the open source code. So that was really work for the cacti case to the now people realize to the what the mashup is and what the interoperability problem is. So the I think that that was a strong reason now from our company to be open source is important as a tool for the to share or to getting the consensus on the ideas. Thanks and condos on I have a question for you. So soft bank is obviously a top global financial institution. What do you think the biggest future opportunities are for decentralization and finance. So about finance. So now with we collaborate on insurance and bank bank and so on about AI solution and data solution. But now a relation of but but I think a relationship of trust between main banks and regional banks as well as cross industry collaboration between insurance and banking is becoming essential. And I think a focus on data authentication on both sides is also becoming necessary. So and in Japan our customer insurance and bank is researching blockchain technology. So I have to supply as soon as thank you. Great. So I'd like to pause now and ask if anyone in the audience has any questions before I keep asking questions. Happy to hand out a mic for people that have questions in the audience. Yes please. Hi. Thank you for your great presentations and discussions. I'm a kind of big fan of decentralized technology and especially decentralized identity. I'm now strongly interested in the proof of concept you mentioned using slide about the academic use case using decentralized identity ID. Are there any kind of detailed information already published we can access to website or documents. So I'm really interested in what kind of decentralized identity are used in that concept or what kind of hyper ledger projects are related to the project or such kind of detailed information is what I want to see. Thank you so much. So maybe I maybe we can open the next year. So now we are now we begin to POC. So but I hear I I was I was hearing several university in Tokyo. So and university person want to make the community of our current university student and I mean I mean I mean it I'm a graduate graduation graduation students. So and they won't come. University university staff want to want to collaborate company company. So they are interested in this case. So if you have a chance I want to discuss with you. So and please advise for me. So thank you. Thank you so much. As I'm talking about the from other the government member of the hyper ledger that we had a special project named at least for the more generic use for the library and we are having a new project and a credit that is more centralized or the focus on the zero knowledge proof other moments. So I think that that will be make a interest to you. So please join us. So that is our kind of presentation. Thank you so much for that. Thank you. Thank you. Put your motor son. You mentioned the security token use case. And so in Japan we obviously have security token regulation now for two and a half years or so. We've got a few platforms in existence. We've got prog met which has by far the largest volume boost trees as other coming. How much space is there for other platforms at this point to still come to market and play a role. I think that I am not the position for the future. But I think that we will be now the unified to the similar platform because of the other. There is no point to the different platform will be kept as a separate. However to the other the concept of the security the management perspective that might be the the isolated from the other competitors even the security companies. So that case is still that they need to be away or they could keep. They want to keep their own solution. That case that we can use to the cacti for the are we into the such a variant and diverse for the interface perspective. So that is our assault or expectation for the how can the security market will be changed by I think we have time for one more question if anyone would like to ask. Hi. Thank you for the great talk. I have a tangential question to this. So many people are concerned about the energy consumption of blockchains. And of course we are looking at a private blockchain which is much smaller. But still is there a way to put those things in perspective when we deploy them in practice. I think to the in general to the enterprise blockchain is designed for the not to use to the proof of work. So the I think to the other it was other we cannot reduce to the other the energy consumption than the legacy system. But that is just better than the ordinary blockchains are public chance. That is our rough assumption for the energy consumption improvement from the current blockchain world. Is that answering your questions. Yeah. Thank you. All right. Well thank you everybody. I think we're out of time. If you have more questions, you know, please find any of us or talk to us. I'm sure you know condos on and Fujimoto son will be around to you know afterwards or you can find them where should people find you for your contact information. LinkedIn or great. Thank you all very much for your time and thank our speakers.
