Iroha accepted by the Linux Foundation's Hyperledger Project

Soramitsu Co., Ltd. (Co-CEOs: Makoto Takemiya, Ryu Okada; hereafter, Soramitsu) developed an open source distributed ledger (i.e., blockchain [1]) platform, Iroha, and submitted it to the Linux Foundation's Hyperledger Project as an incubation sub-project.

Iroha was accepted into incubation status and will join IBM's Fabric and Intel's Sawtooth Lake as the third distributed ledger project with incubation status.

Iroha is a new distributed ledger platform that was developed from scratch and proposed to the Hyperledger Project by Soramitsu, NTT Data, and Israeli startup Colu, among others, on September 26th, 2016, in Geneva, Switzerland. On October 13, 2016, Iroha was officially accepted into incubation status.

Soramitsu's Iroha Distributed Ledger Platform Accepted by the Linux Foundation's Hyperledger Project as the Third Platform with Incubation Status

Iroha aims to provide a secure and decentralized data management platform for financial institutions, as well as many other fields, such as healthcare and logistics. Using the custom "Sumeragi" consensus algorithm, Iroha aims to provide consistent transaction finality within 2 seconds, making the platform useful for many real-world scenarios. To provide high throughput scaling to thousands of transactions per second, Iroha uses UDP multicast and C++ for data processing.

To explore use cases and work to increase the viability of the Iroha platform, Sompo Holdings Inc. is working with Soramitsu to create derivatives on top of the distributed ledger. The University of Tokyo, the University of Aizu, and the Center for Global Communications (GLOCOM) of the International University of Japan, are also working with Soramitsu to study the economics of local currencies and their effects on regional development. Joint research in the area around Aizu, in Fukushima Prefecture, Japan, will include experiments using local currencies running on Iroha.

In addition, with Rakuten Securities, Inc., Soramitsu has announced that they are working together to develop a KYC [2] system using blockchain technology. Mizuho Information & Research Institute, Inc., is also exploring the use of Iroha.

Soramitsu is committed to the development of blockchain systems that can contribute to society by providing safe and secure data management. Partners who want to contribute to Iroha and also work with Soramitsu on creating services, especially a digital identity KYC service for financial institutions, are invited to contact Soramitsu. Iroha is open source and anyone can contribute to it at
