Fujitsu and Accenture Join Hyperledger Greenhouse with Blockchain Interoperability Project

May 19, 2020

Fujitsu and Accenture have officially joined the Hyperledger Greenhouse with a new project focused on blockchain and distributed ledger technology interoperability. Hyperledger is a global, open source consortium, hosted by The Linux Foundation, and dedicated to advancing cross-industry blockchain technologies.

Formerly known as the Blockchain Integration Framework, the Hyperledger Cactus project has been in development in the Hyperledger Lab for the past six months. It's the 16th technology code base for the Hyperledger Greenhouse, along with other projects like Hyperledger Fabric and Hyperledger Sawtooth.

Hyperledger, which is comprised of more than 250 companies, is focused on developing distributed ledgers and smart contracts to cut the cost, complexity and risk of centralized systems. The organization promotes open, transparent governance, modular technologies and is now focusing on interoperability.

“Hyperledger Cactus serves as an option for enterprises wanting to connect any DLT to other DLTs through a plugin," Michael Klein, director of blockchain technology at Accenture, told Cointelegraph. "Cactus can be used on any permissioned DLT network where you have known identities or validators in an interoperability framework.”

The Cactus Apache V2-licensed open-source software development kit may be executed on Hyperledger Besu, which runs on the public Ethereum blockchain. It may also be executed on Hyperledger Fabric, the Ethereum-based Quorum and R3's Corda platform. It is designed as a pluggable architecture, enabling the execution of ledger operations across multiple blockchain ledgers with support for additional blockchains to be added in the future.

"We live in a world of many networks and databases with differing business requirements," wrote Klein in a blog post announcing the Cactus project. "Some need to be fast, some need to store a lot of data, and some need strong resilience properties. As businesses replace traditional infrastructure with multiparty systems, we need blockchain technology to handle a wide variety of possible use cases and requirements. In other words, there will be no 'one blockchain solution to rule them all.'"

The next step for Hyperledger Cactus will be to gain ideas and support from throughout the blockchain community, and incorporate those ideas into the architecture. The project will also finalize its modular, pluggable interfaces to enable project members, as well as those outside Hyperledger, to take advantage of the solution for blockchain interoperability.
