 So, hello everyone. I think it's about the time to start. So, I'd like to start my presentation titled, Cactus Helps Cross-Industry Collaboration to Tackle the Climate Change. So, first of all, I'd like to introduce myself. I'm a project manager in the Fujitsu, and I also double identity as a governing board member in the Hypervisor Foundations, and that is very my proud to be presented here in such many people in front. So, because of my career in the Hypervisor Foundation was as a maintainer of Cactus, but now that role is taken over by teams and now there are more involvement in the deployment in the real businesses. So, today I will present to you the topic of the talk with our partner, IHI, who is very eager to solve the problem on the climate change as a responsibility of the industry leaders. So, because of the wear comes from the blockchain world. So, many times we are talking about how our technology can be used to the fact. However, to our customer had a different perspective because the problem is always first and the one of the solution could be a blockchain. So, when we need to be involving to such a climate change, first of all we need to be the pathway to them to use the five blockchain is needed to solve the problem. So, this particular problem like the climate change is a simple problem that we need to reduce to the carbon emissions. This is the same of the previous presentation in this room, the SDG 13 was clearly said we need to be tackle the climate change based on the to reduce the impact of the environments. So, because of the Japanese, I'm from Japan, the Japanese government also agreed to achieve to the earlier goal, 2030, to achieve to the GHD emission into the impact zero. So, that is not the meaning of the wear are perfectly working as the emission zero because I will talking about the fire it was, it is very difficult in certain industries. And I also mentioning about the mechanism about the carbon offsetting. So, the carbon set is sometimes misunderstood by the that is only the model of the well trading the variable, that is not. Because of the sometimes for the in Japanese government perspective they encourage to such a trade within the same country. Otherwise, those are only the investment for the another country and that will not contribute to the better environment in our own countries. So, before the jumping to the real problem I will explain about the fire we choose to the partner as IHI because IHI is a heavy industry company and they have a very serious problem to reduce to the other carbon emissions. For the chemical plants and they need to be product of the materials like steels and they create the aircraft they cannot be fly by the electricity. So, those are the heavy industry is the one example of the industry that it always tackling to the unavoidable CO2 emissions. So, they really want to contribute to the other to reduce the CO2 emissions. However, they cannot in directly. So, the another well the scheme for the carbon offset is that is the previous presentation also mentioning that the mechanism is simple. So, that is a balancing mechanism of the who actually producing to the CO2 that is a supposedly evil things but also the another that will be balanced with the good guys that they produced the way to reduce to the emissions like for example keep the mountain for the instead of destroy it. But the both of the other actions are required to the some found to help. So, the carbon offset mechanism is not only the balancing to the such a value other into the zero they need to be collaborate to each other in finally. So, this diagram is showing to the how the other carbon set work. So, the left hand side is let's assume to the that company decided to replace to the boiler from the old one to the new one. And new one is a better quality but still that need to be a higher cost to earlier early adoption or deployment. So, the that company need to be some sort of the assist of the to encourage to the such a new investment. So, the such company like IHI maybe the help in fundamentally in the farm in money. So, the those case as someone in the mentioning the current situation is that we have a public market have the certain the certified environmental values on registered on the central registries and that will be exchange. So, the other but that is still the problem because of the there is a no way to truck into the original value on the market or on the market. That is the merely the measurement of the carbon emissions or the reductions. So, the but the all the company need to be proved that they're good behavior to the their investors or customers. So, the the new aspect of the our mechanism is we need to be the verification mechanism that is executed by the third party that supposedly the trust was the organizations. So, this is the kind of bit technology parts but the fire we need to be using to the blockchain technology for the that model is the blockchain as a nature they have the three functional requirement that is the one of the trade. The first one is the verification. So, the the blockchain is allowing to the not to self prove. That is the proved by the another third party the engineer that record is correct. So, the all record on the blockchain is automatically verified and later on we can check to this that the the truthness. And second thing is the governance. Yeah, because of the environmental trade is the the many people involved many players involved. So, the even the same company are the they have the certain long big supply chain like the companies or partners or supplier and so on. So, the if we need to be the those are the kind of mixture mixed information into the single consistent way we need to the blockchain because of the blockchain is the only way to prove to the other things other and record the those are the original data into the other result data consistently using to the smart contract. And third thing is sustainability because of the other that is dependent on the how the blockchain is managed but most of the blockchain currently is the because of the their trial other private chain is still exist. However, the for the carbon offset is some sort of the public sector or public the services. So, we think to the those blockchain has to be managed and run as a consortium chain which is maybe the governmental or other responsible companies need to be managed. So, the those three aspects will be automatically or other has to be achieved by the design of the blockchain systems. So, the the back to the original field so the other this is a kind of concept of the our idea for the how we need to be changed using to the block chance. So, the other left side is a study with the deployment of the new equipment but that with that will be the creating to the that need to be provide the measurement of the how that equipment to improve to the previous I compare with the previous one. So, the those information will be recorded on the radio on the single company managed but that radio will be managed by the consortium way. But the doesn't matter to the how the radio is managed the the leisure entity should be separated on the each supply chain like the company and company B might be liable do not want to share to the their record on the same leisure. So, the in those cases always happen. So, the we are thinking about to the those leisure record will be a separate rerunning at least. Also, when we need to be executed to the transferring to the such environment value across or the industry or between the companies. That is also needed for the proof of the transfer outside of the those two. So, the other nature we can see the at least the three leaders are the separated but they are connected each other. So, the here's our technology connection chain. That is a well that we design for the public in the back to the 2017. That time we only care about the exchange of the cryptocurrency but now the time is coming and we need to be a this technology into the using of the non-financial asset like the environment values. So, the we did not expecting to the real problem for the interworking of the blockchain. The connection chain is a blockchain to unite or integrate to the multiple blockchain not only the two blockchains but the other frame we started to the project. We need to be implement for the each adapter for the the different regions because of the customer choosing to the free choice like some people like a Ethereum and some people like a public. So, it is that time the other those blockchain cannot be communicate each other securely. So, we are going to start to the the hyper leisure project cactus that is one of the category of the tools currently. The fight was to because of the cactus is not a final product that is a tool to provide to the better interoperability to access to the any kind of the blockchain as a design. So, the cactus has a well had a lot of the interest in the hyper leisure community and many people willing to contribute. So, from the beginning we only had a merely one or two. The blockchain was supported but after the two years during the coronavirus that we had a plenty number of the at least the all the DLT technology within the hyper leisure umbrella is already supported. And we also keep updating for the new technology like Irohore version 2. So, the right hand side is well the because of the concept of the cactus is pretty difficult to understand. The cactus provide to some of the example application like the discounted cut rate. I will explain to you some details for how the cactus can be used. So, the concept is the because of the cactus will provide to the some of the intermediate infrastructure so any application can use to the cross chain or same chain operation will be through the common API. But the cactus did not remove to the difference of the blockchain intentionally because of the difference of the blockchain is always the strength of the DLT technologies. So, we make a choice of the instead of the removing from the abstraction we removing to the communication part only for the inter PPD purpose. So, the some news announcement is as Daniel mentioned this morning yesterday we had well the Hyperledger Foundation make the big press releases and sorry the very almost end of the those good news that we have the small news like about the cactus we have the new name of the cacti that is the new project name so the cacti is using the technical benefit of the cactus and the waiver that has some similarity and now those people are getting together and to create to provide the better inter PPD in the Hyperledger community so the behavior of the cactus is kind of easy or simple that is started with from the user's point of view that looks like one of the web services and that will request to the trade for the well let's say we want to use it to the car for 30 minutes but I want to getting to the corporate discount because of the my company the contract so that case the user will need to be provided their asset key and the credentials and also they want to provide to the identity information to be proved so the cactus application will interact with each chain for the based on the requirement they need to be checked to the identity the cactus will communicate to the and when they need to be withdraw or deposit the money that will access to the financial tokens on the Israel and finally to the right to use was managed by the fabric that will be the interact with the fabric so those combination is freely designed by the programmers the perspective so the I think to the that will be the fulfilled the some application on the net so the I think to the need to be missing part here so I believe to the that is fulfilled by the firefly or some other application layer so that is a just a well information so now back to the original story so the I think to the we need to the unite or integrate the three blockchain that was our previous stories so the other to build to the dot system the interworking with those two and also the because of the our connection chain is designed for the its own the blockchain behaviors we are providing to the other smart contract to which can communicate with another block chance that is extended part so the other result we could build to the whole with the as the consistent way with hi the 30 because of the hi is a company to provide to the information on the the machinery senses sensing data into the block chance and Fujitsu provide to the financial at the tokens which will be the use for the settle the blockchain trading and we also provide to the another blockchain based on the fabric as a imitated trade party that we transfer to the hi is value to the other one so the we are the remarkable because of the we are the same the companies we also discuss with the Japanese government for the other feasibility of the how we can adapt to the current markets so they said to the the central repository is still needed so the we designed to the system with jcredit is a kind of Japan wide the central repository managed to the value for the other value but we also keep the consistent of the original information or keep the those information into the their own private chance and we unite to the how those repository can be referred or created so that way the connection chain Fujitsu will provide the evidence or proof of the transfer and also the proof of the the tokenize the actual made sensor measurement into the environmental values so the other the all the details are described in the joint press releases so the if you are some interest that please look at our press releases in English but beyond the other what we did the we are expecting to the enlarging or enhancing to the community as a more bigger or valuable things because of the we only the tried on the how the carbon emission can be used on the replacement of the equipment however the environmental actions is available like a well let's say we need to be more trees or let's say that we need to be deduced to the vessel or something like that garbage is yeah so the there is a so many the the the climate action the the involving those are the required for the some investment from the other good readings so the we are the reading to creating to the such a bigger the ecosystem not only the simple use but those are the exchange of the those values are the very depend on the realness of the investors like some people said this is a well we need to we need to be invest on the reducing to the carbon offset someone wanted to direct to the contribution like we want to get into more trees so the those are the the diversity of the wheel should be integrated as a blockchain system that is our the concept of the collaboration with the IHI so because of the this is a very the cutting edge the initiative so the we are just started to the with our close partner IHI but the both company agree to the that is not should not be ended up with two companies we really want to join to the many people who are in mind and same the thinking so the other I believe to the other this is a good chance to present to this in the European countries because of the European countries and people are very the sensitive and eager to reduce to the CO2 emissions so the I hope to the my presentation help to the your understanding of the the blockchain potentials and the potential of the CACTI as a new project this is the end of my presentation thank you very much so I think I have some questions Mr. can I have a mic yeah the end room ended thank you for an excellent presentation at a question so you have sensing data coming in feeding a smart contract now usually when you have sensing data translating into a monetary value you need a custody transfer quality metering with accredited meters that have the right certification everything to the actually metering the right way so have you been able to think about how you can integrate that into a smart contract that is actually measured by a certified meter yeah I think that is quite a good question because of the those are very depend on the how the those ledger will be build or design so the we assume to the some variety one of the type will be simply keep the record of the measurement of the sensor however to the another type of the regular smart contract will automatically calculate it based on the GHD protocols that is translated to the based on the measurement into the actual CO2 calculations will be done by the smart contract so the the former part case because of the that is the measurement like the data chain or the representation the previous days that data will be need to be tokenized by the another program or smart contract so that need to be if that is the case that one will be break into the more smaller piece like the simply recording right-weight measure with smart contract can calculate to the environmental values but the other cactus is nicely handled those kind of the varieties because of the that is the application logic need to be the adapt to the such a differences so the what we need is only the how the those are the data or value will be recorded and how the those value can be safely transferred as a contracted way I mean to the that is a human contract I think so the that part is we need to do the some technologies like extended smart contract here thank you Mr I have two questions for you yes correct so the actually to the for the case of the our the case we are technical for the other measurement of the periodically because of the metering is like some sort of the design for the no back way so the other even the those the duration will be let's say one day that could be okay because of the that is consistent with the previous value as a sum up to the other record so the but still that we have the potential problem for the everything on the blockchain using to the smart contract so the other that is not the depicted such a detail but I think to the company need to be subsidiary the block chance as a shading techno at technique record dividing to the small pieces will be integrated to the one the logic some people propose that instead of storing everything on blockchain we can store it on off chain and kind of store a link on the blockchain so do you think that is the right way to go I think to the other I do not say that that is good or that is bad other that the I think to that it depends on the needs so the for the case of the we only require for the evidence of the very scientific things so the that to be okay but I said to the other my customer was willing to getting to the some achievement like a I'm doing good things like a well the how we contributed it should be the visualized so the exact case is the blockchain might be helpful maybe the comment on your on your question I mean what you are trying to say is exactly what addresses the value of blockchain interoperability you can if blockchains can interoperate you can imagine different networks providing dedicated functionality depending on the specific blockchain technology that has been employed like for example you can have a high-performance permission network collecting the data from the sensors and using only a public let's say lower performing non-permission blockchain network like Ethereum for example only for the relevant value exchanges and if you if you can employ different blockchain technologies working together then you can cherry pick the features that you need from the technologies that are really relevant for each let's interface to the outside world I think the similar kind of thing we are doing in this climate action accounting project so for recording a sense sensor data or carbon would pin data in a high-pressure fabric and then using this data in a EVM based blockchain so tokenize it because in the fabric you can use the data because the permission network you on the nodes you can decide the size and everything I think that is the area of the climate change working group I think I'm eager to working with you as a within the same the organization but the unfortunately to the cactus was a new B for the other this community and during to the corner the virus situations so the we had a less opportunity to talk to each other yeah so even we are working with Peter from the cactus team to even using the cactus in the same project there so we ran couple of mentorship programs for that one yeah so that already we implemented the cactus in there in the same project sure so that is a very good news for the we had a new cover for the ecosystems so the basically to the other you the question is a very positive because of the that is the bigger problem for the industries for the to tackle the environment so the but today I will providing to the information about to the why we need to be used to the blockchain as a business logic and also that we need to be we have some tools to help the those initiatives so I think it's almost the time of the ending so I may take one last question so do you have any volunteer to not I think sorry yeah other please give the mic who who we misunderstood okay fine so they thank for the the participating to the discussions and the this is the end of the discussion thank you very much
