Hyperledger, the Linux Foundation’s open business blockchain consortium, has announced the launch of the first production-ready version of Hyperledger Iroha, a general purpose permissioned blockchain system designed with a focus on simplicity and mobile-oriented business use cases in finance and identity management.

Hyperledger Iroha is the fourth active Hyperledger project to reach 1.0 following Hyperledger Fabric, Hyperledger Sawtooth and Hyperledger Indy. Hyperledger said the release will complement the organization’s projects by providing an alternative solution for implementing blockchain networks to mobile devices.

“It’s extremely gratifying to see another one of Hyperledger’s active projects hit the 1.0 milestone,” said Brian Behlendorf, executive director of Hyperledger.

“This is a huge testament to the strong collaboration of our growing community. I look forward to seeing development efforts around Hyperledger Iroha continue to grow and more and more productions systems powered by the framework later this year.”

According to Makoto Takemiya, a Hyperledger Iroha contributor and the CEO and co-founder of Japanese blockchain company Soramitsu, it takes just ten minutes to begin building a blockchain with Hyperledger Iroha.

“When it comes to solutions for business, it is critical that the technology is fit for the task and easy to integrate. Moreover, it must be reliable and safe so a business can trust it,” Takemiya wrote in a blog post.

“Hyperledger Iroha provides safety with its decentralized consensus algorithm and reliability with a tested set of commands and queries. With them you can be sure that the code will do exactly what it is supposed to do — whether you want to add information to, or get information from, the ledger.”

Hyperledger Iroha has already gained traction with the community and enterprises, Takemiya said. The Moscow Exchange Group’s National Settlement Depository is using Hyperledger Iroha in D3 Ledger, an interoperable blockchain network enabling financial institutions from different markets to issue, store, trade, and exchange digital assets. The platform is also being used in asset management, identity management, and payment systems.

Hyperledger Iroha comes with an easy-to-use API and a universal peer model. It has a modular architecture making it additive to existing projects using other Hyperledger technologies and provides a library of reusable components. Blockchain-powered applications can be written in Python, Java, JavaScript and C++ as well as for the Android and iOS mobile platforms.

Key features of Hyperledger Iroha 1.0 include its Byzantine fault tolerant consensus algorithm, called YAC, that is high-performance and allows for finality of transactions with low latency, as well as fully operational multisignature transactions.

Hyperledger Iroha was contributed by Soramitsu, Hitachi, NTT Data and Colu.
