Hyperledger, the open-source, cross-industry collaborative effort focusing on blockchain technology, has advanced the status of its Sawtooth and Iroha blockchain frameworks from “Incubation” to “Active” status.

The green light was given by Hyperledger’s 12-member Technical Steering Committee (TSC), chaired by Christopher Ferris, CTO of Open Technology at IBM. It followed an extensive review period during which each project was evaluated based on exit criteria that include legal compliance, community support, test coverage and continuous integration support, documentation, code reviews and more.

Ray George, senior director of PR at the Linux Foundation, told Bitcoin Magazine that “there is no difference [between Incubation and Active status] when it comes to how the projects are expected to run and how the TSC works with them to ensure a healthy community continues to be built.

“The most tangible difference is how this is presented to the public — not as projects whose communities are still finding their bearings, but as communities ready for new contributors and whose users can depend upon those communities persisting for the long term.”

Hyperledger Iroha, which was initially proposed by Soramitsu, Hitachi, NTT DATA and Colu, is a business blockchain framework inspired by Hyperledger Fabric. It was designed to be simple and easy to incorporate into infrastructural projects requiring distributed ledger technology, and aims to provide a development environment where C++, web and mobile application developers can contribute to the Hyperledger Project.

Hyperledger Sawtooth was initially contributed by Intel and designed to explore scalability, security and privacy questions prompted by the original distributed ledgers.

The modular platform allows organizations to build, deploy and run complex distributed ledgers, and includes a novel consensus algorithm, Proof of Elapsed Time (PoET), which targets large distributed validator populations with minimal resource consumption.

Sawtooth and Iroha follow Hyperledger Fabric, the first project to graduate in March 2017. These projects, alongside five others, all fall under the Hyperledger organization umbrella, which focuses on bringing together software developer communities to develop open-source blockchain and smart contract related technologies.

Projects currently in Incubation include Hyperledger Cello, a blockchain module toolkit; Hyperledger Composer, a set of collaboration tools for building blockchain business networks; and Hyperledger Explorer, a blockchain explorer for viewing, invoking, deploying or querying blocks, transactions and associated data.

Hyperledger’s Membership Expands

The news of Sawtooth and Iroha moving out of Incubation broke on Monday at Consensus 2017, a major blockchain-focused event taking place this week in New York, during which Hyperledger also announced the addition of eight new members, bringing its total membership to 142.

New members joining the Hyperledger Project include Deloitte, Ernst & Young, Schroder Investment Management, AlphaPoint and Change Healthcare, one of America’s largest healthcare IT companies and the first healthcare organization to join at the top membership level.

Change Healthcare’s CTO, Aaron Symanski, will be joining the Hyperledger Governing Board, chaired by Blythe Masters, CEO of Digital Asset, and consisting of representatives from 20 members of the Hyperledger membership.

“Blockchain [technology] is a promising and exciting new technology for secure online transactions,” said Symanski. “But it is crucial that healthcare leaders step up to champion innovation to help take blockchain [technology] from its early implementations to tomorrow’s healthcare IT solutions.”

In October 2016, Hyperledger kicked off a Healthcare Working Group to advance blockchain development in the healthcare industry. The group now has more than 425 technologists and executives representing the likes of Accenture, Gem, Hashed Health and IBM.

Another company that has joined the Hyperledger Project is FZG360 Network Co. Ltd., a leading real-estate portal and trading platform in China, which aims to “enhance the application of [blockchain technology] to a higher maturity level,” particularly in the area of real estate.

Hyperledger was founded in December 2015 by the Linux Foundation and counts among its members leading firms representing various industries including blockchain technology, finance, healthcare, the Internet of Things, aeronautics and real estate, among several others.
