Accenture–Fujitsu Project Hopes to Solve Blockchain Interoperability

While interoperability continues to pose serious challenges for enterprises leveraging blockchain networks, companies may be one step closer to breaking down these barriers.

An open-source project initiated by Fortune 500 company Accenture and Fujitsu joined Hyperledger’s Greenhouse on May 13, 2020. The project, formerly known as the “Blockchain Integration Framework,” spent six months in development in the Hyperledger Lab before joining the Hyperledger Greenhouse as the 16th technology code base. Upon joining the Greenhouse, the project was renamed “Hyperledger Cactus” and now sits alongside notable projects including Hyperledger Fabric and Hyperledger Sawtooth.

The director of blockchain technology at Accenture, Michael Klein, told Cointelegraph that Hyperledger Cactus is an open-source software development kit designed to connect distributed ledger technologies through a plugin:

“Hyperledger Cactus serves as an option for enterprises wanting to connect any DLT to other DLTs through a plugin. Cactus can be used on any permissioned DLT network where you have known identities or validators in an interoperability framework.”

Klein noted that Hyperledger Cactus can be executed on Hyperledger Besu, which runs on the public Ethereum blockchain, along with Hyperledger Fabric, R3’s Corda and Quorum (Ethereum-based).

Why is interoperability important?

The executive director of Hyperledger, Brian Behlendorf, told Cointelegraph that there are two layers of interoperability. He explained that the first relates to interoperability within a given blockchain network, noting that everyone on the IBM Food Trust Network, or the Trust Your Supplier network, or other similar networks powered by Hyperledger Fabric, can exchange information efficiently and correctly:

“This is where ensuring everyone is using the same software (e.g., Hyperledger Fabric, or Hyperledger Besu) is the most important piece, as well as setting up a governance structure for the participants on…
