EEA Member Spotlight with Tetsushi Hisata, Founder and CEO of Datachain

As an EEA member, Datachain is part of the EEA community of organizations working to advance Ethereum and drive industry adoption. In the Q&A below, the EEA interviewed Founder and CEO Tetsushi Hisata about how Datachain is contributing to the ecosystem to help Ethereum reach its full potential.

Please introduce your company and yourself briefly.

I am the Founder and CEO of Datachain, a startup working to solve blockchain interoperability challenges. Datachain decided to join EEA because we want to learn and engage with the community around interoperable technology. We are excited to join the EEA’s Cross Chain Interoperability Working Group to learn more and discuss how interoperability can be advanced.

Datachain has been working on an interoperability effort called YUI. “YUI” is the Japanese word meaning to knot, join and connect, and the YUI project is a Hyperledger lab to achieve interoperability between multiple heterogeneous ledgers. The YUI project provides modules, applications, and middleware for cross-chain communication and development, including an explorer to track status and events for cross-chain environments. Since YUI supports both Enterprise Ethereum (e.g. Hyperledger Besu) and Public Ethereum, it can connect the Ethereum blockchain with other blockchains to expand the possibilities.

How will end-users benefit from your Ethereum interoperability work?

Among the modules of the YUI project, which applies Cosmos’ IBC Protocol to the enterprise space to enable interoperability between various blockchain platforms without relying on third-party trust, we are focusing on implementing IBC-Solidity, a Solidity implementation of IBC (Inter-Blockchain Communication), with a grant from the Interchain Foundation. With the implementation of IBC-Solidity, the Ethereum blockchain will interoperate with other blockchain infrastructures using IBC. We are also working on the Cross Framework, which enables Cross-Chain transactions between different blockchains.

How will the EEA enhance your organization’s current efforts?

By participating in the EEA’s Cross Chain Interoperability Working Group and connecting with EEA community members, we would like to consider the commercialization of Datachain technology in specific projects. In Japan, we have been working with a number of companies such as NTT Data and Hitachi on interoperability, and the EEA will help us expand our efforts globally.

What about the EEA are you most excited about?

The Ethereum blockchain, both enterprise and public, is being used in various projects worldwide, and we believe that new value will be created when such projects connect with projects built on other blockchain platforms.
