Empowering Blockchain for Smart Living | Blockchain EXE in Singapore - Aug.16

Blockchain EXE Asia Tour in Singapore
These days the brand-new technology “Blockchain” is being developed by many engineers around the world. One of the Japanese startups Couger inc. is the pioneer of social implementation by using Blockchain. To put Blockchain into practice, we need to meet some problems by discussing or exchanging thoughts with a variety of people, beginner to high level of engineers. This is the reason why the community “Blockchain EXE” was born in Japan. This report is the record of presentations made by some specialized engineers from many different countries.
Data sharing for smartliving | Mike Anderson (CTO at Ocean Protocol’s DEX)

Ocean Protocol is a leading tech company in Berlin
Mike works as CTO at DEX, and DEX is a traditional data marketplace company that opens up data for hackathon or researchers.
He thinks that researchers have many smart algorithms for AI, but not sufficient data. On the other hand, government has tons of individual data but doesn’t have ways to make valuable use of it.
The brand-new technology “Blockchain” is useful for meeting this problem for many reasons.
His main idea for presentation was about “Ocean protocol”. It is explained as “a decentralized data exchange protocol to unlock data for AI”.
“Ocean” enables data with “supply lines,” and the following points are the key features.
・Open standard
・Decentralized responsibilities
・Trusted data
・Orchestration via Ocean Protocol
・Immutable provenance
・Integration with Data Commons
He wanted to make smart living opportunities with Ocean protocol and believed that collaboration of data marketplace and Blockchain technology will make a more trusted system.
GSE Network | Harry Toh (Head of Business Development)

Partnership with Tech Giants
GNE Network has partnerships with many huge companies, such as “ofo”, the biggest bicycle-sharing company in China, “airbnb”, “UBER”, “accenture” and so on.
Thoughts on Global Sharing Economy have been spread, but there are some problems limiting the potential of it. High intermediary fees, trust gaps, monopolistic and fragmented landscape, and lack of risk mitigation are some examples of problems.
To build a decentralized trust network for sharing economies on Blockchain technology, the following technical architecture is needed.
・ Decentralized App Layer (DApp)
・Decentralized Service Layer (DService)
・Public Chain Layer (GSENetwork)
In addition there are 3 pillar infrastructure solutions.
・ Decentralized Service (DService)
Providing robust distributed services infrastructure to support sharing economy business.
・Incentive Model
A revolutionary green-mining approach to mine tokens through user engagement in the sharing economy.
・Trust Network
Trust will be qualified within the trust network. User will be able to build their own trust profile with every interaction within the global sharing economy.
Finally, Harry said that in 2019 he is aiming to launch his public chain to real life.
Biometric verification technology with blockchain | Ken Naganuma(Researcher at Hitachi)

Ken Naganuma from Hatachi Japan introduced his idea of a smart city in the point of key-management technology for blockchain.
His main point was how to solve the inconvenience of key-management in Blockchain, and his solution’s name was called “PBI”(Public Biometrics Infrastructure), which means our bio-info(like fingerprints) are our secret keys.
The problem of traditional bio-autho systems was if you lose your computer device, you couldn’t access your assets in the Blockchain, and other people might steal your secret key.
However, PBI-BC(BlockChain) system is clever in the point of when you scan your bio-info and generate secret key to access the blockchain, the secret key and bio-info will be deleted immediately. The next time you use the blockchain, you should scan your bio-info again and generate different secret key as before to access the blockchain.
Then he did the demonstration of Hyperledger Fabric v1.0
Applying the Autonomous Gateway, “Connectome” to Smart City | Atsushi Ishii(CEO at Couger)

“Connectome” is the brand-new technology of AI×Blockchain combination. Using “Connectome”, they create “Virtual Human Agent”, and also develop “Smart Space” project with KDDI, one of the biggest communication companies in Japan. Singapore is the leading country in developing “Smart Space”, so they discuss about the world’s future concept by reviewing real world problems as a start to the Asia Tour.
At first, developer of Connectome Ishii (CEO at Couger inc.) introduced how the world is going to be Smart city in a few years.
Also he mentioned about structure limits and predictable problems.
Blockchain Giving Credibility to AI | Kazuaki Ishiguro (Lead Blockchain engineer at Couger)

Next speaker from Couger inc. was Ishiguro(Leading Blockchain Engineer). He develops service called “GeneFlow” which make AI’s learning process transparent.
He also has a role in a Japanese regional head of Enterprise Etherum Alliance.
There are some problems with privacy when the Blockchain is used in companies.
He explained about how to protect privacy and manage high transparency at the same time through watching demonstration videos of systems developed.
Pannel discussion

Finally all of the presenters - Atsushi Ishii, Mike Anderson, Harry Toh, Ken Naganuma, Kazuaki Ishiguro (pictured above from left to right) - had a panel discussion about today’s theme of “Smart Living”.
The question was “How do you meet the problem of aging? It might be difficult to catch up latest technology for elderly people.”
Mike and Harry answered “Combination of passive sensing and AI, in terms of data training is sort of the key to solve the aging problem” and “Sharing assistant will help aging people.”
Atsushi said “What we need to do for people who find it difficult to use technology is to develop a more natural interface and that’s exactly what Couger was working on the project of human interface.” Ken commented that “Since Blockchain is decentralized, you can distribute service to all smart contactors and it's very suitable for smart city. ” Kazuaki mentioned about making documents of describing how to use the technologies in easy language.
The next question was “Do you have anything to do with community building or corporate standard?”
Ocean protocol’s Mike said “Making our software open source and encourage different communities to participate in using tools and solving problems and that is the central part of our strategy building ecosystem.” Harry mentioned “The biggest problem in smart city is trust and reputation, so we are basically trying to create entire Blockchain ecosystem which all decks have trusted profile.”
Big potential of Blockchain in Singapore
Blockchain EXE in Singapore had been getting into swing from beginning to the end for some participants were standing to watch. At this time, various AI startups from robotic industry to data marketplace were collaborated into one place, so the event had very rich contents.
