Today at Consensus in New York, we’re happy to announce that Hyperledger’s Technical Steering Committee (TSC) has granted the Hyperledger Iroha maintainers’ request to advance the project’s status from Incubation to Active. 

While Hyperledger Iroha has not yet reached its v1.0 Production release, the TSC members unanimously agree that the project has satisfied all of the Incubation Exit Criteria. The exit criteria by which projects are evaluated in order to graduate from Incubation include legal compliance, community support, test coverage and continuous integration support, documentation, architectural alignment, published releases, and infrastructure support for such things as requirements and defect tracking, code reviews, continuous integration testing and more.

We’ve often been asked what tangible differences exist between an active project and one in incubation? To be clear, there is no difference when it comes to how the project is expected to run, and how the TSC works with it to ensure a healthy community continues to be built. The most tangible difference is how the project is related to the public – not as a project whose community is still finding its bearings, but as a community ready for new contributors and whose users can depend upon that community persisting for the long term.  

We first welcomed Hyperledger Iroha into incubation back in November 2016. Hyperledger Iroha is designed to be simple and easy to incorporate into infrastructural projects that require distributed ledger technology. It features a simple construction, modern, domain-driven C++ design, emphasis on mobile application development and a new, chain-based Byzantine Fault Tolerant consensus algorithm, called Sumeragi. Hyperledger Iroha was initially proposed by Soramitsu, Hitachi, NTT Data, and Colu.

Hyperledger is an “umbrella” for software developer communities building open source blockchain and related technologies. Hyperledger Iroha falls under that umbrella and is the second of eight Incubator projects to graduate. The first of which was Hyperledger Fabric, back in March 2017.

This is a huge step for the Hyperledger community. The graduation of Hyperledger Iroha represents a milestone for the community as a whole, and I am eager to see the other projects follow suit. As always, we encourage developers to join our efforts on Iroha as well as other projects, via github, Rocket.Chat, the wiki or the mailing lists.
