Takuma Takeuchi
Fujitsu Limited, Senior Researcher

Takuma is a Senior Researcher of the Data & Security Research Laboratory within Fujitsu Limited, responsible for blockchain interoperability technologies critical to Fujitsu's Sustainable Manufacturing plays. He also contributes to blockchain open-source software development as a Maintainer of "Hyperledger Cactus," one of the Hyperledger blockchain interoperability projects hosted by the Linux Foundation.

He has researched blockchain interoperability technologies, and he developed "ConnectionChain," a security technology that can safely and facilely execute transactions across multiple blockchains. He loves software development, and he won the best award at Blockchain Hackathon hosted by Smart Contract Japan.

He is now involved in the development of Hyperledger Cactus for achieving token economies society across various industries, including financial and non-financial markets. In his own words, "I'd like to promote a token economy across industries by taking advantage of each blockchain without being aware of its differences." 


For creating a new token economy beyond financial and non-financial areas, blockchain interoperability has an essential role in interacting with multiple blockchains in various industries. But there are two issues on interacting with numerous blockchains. It is challenging to adjust multiple blockchains because each blockchain has different APIs for posting transactions and getting block data. The other issue is that it is difficult to connect various blockchains because their network setting depends on each blockchain platform.

Hyperledger Cactus is an open-source platform for interconnecting blockchains and activating digital transformation to solve the above issues. Key highlights are the following:
* Absorbed operation: Eliminate the differences such as API calls and the timing of transactions between multiple heterogeneous blockchains
* Bi-directional communication: Enable Cactus to post transactions and get block data via firewall-enabled abstracted operation.
* High availability connectivity: Providing ledger connectivity to 9 ledgers including Go-Ethereum, Quorum, Hyperledger Fabric, Hyperledger Indy, Hyperledger Sawtooth, etc.

Explore the blockchain interoperability experience that accelerates token economies beyond various industries for their business needs. In this session, we will explain the importance of blockchain interoperability in the solutions beyond the industry using Cactus demonstrations about car ownership trades and electricity trades with the combination of Ethereum blockchains and other-typed blockchains.
