Soramitsu Co., Ltd.
Blockchain Platform Initially Developed in Japan Reaches Development Milestone
Hyperledger Iroha V1.0 has been certified as a production-ready Hyperledger platform, offers
simple implementation, advanced permission model, privacy and user protection features
Tokyo, Japan -- ​Hyperledger, a global open source collaborative hosted by theLinux Foundation, announced that it has released a production-ready version
V1.0 of the Hyperledger Iroha blockchain framework​!

Hyperledger Iroha was initially developed and contributed by Soramitsu Co.,
Ltd. (Co-CEOs: Ryu Okada and Makoto Takemiya, Headquarters: Shibuya-ku,Tokyo, hereinafter "Soramitsu"), a key contributor to Hyperledger Iroha
development, end-user applications, and community.
To achieve the 1.0 release, Hyperledger Iroha passed various tests such as
security, stability, and durability audits, as part of the open development andopen governance requirements of Hyperledger, a collaborative with more than
270 members that was created to advance cross-industry blockchain
technologies. As a result, a blockchain platform originally developed in Japan,Hyperledger Iroha, is now the fourth active Hyperledger project to reach 1.0,
following Hyperledger Fabric, Hyperledger Sawtooth, and Hyperledger Indy.
Hyperledger Iroha is designed to allow developers to implement applications
using blockchain in a simple way, yet powerful features such as digital asset
management, multiple signature accounts, and a role-based permission model
provide the tools to realize complex, real-world use cases. Hyperledger Iroha isbeing used by financial institutions such as the Moscow Stock ExchangeGroup’s National Settlement Depository, the Slovenian CSD, KDD, and theNational Bank of Cambodia to build real-world, production applications.
Additionally, a multitude of proof-of-concept applications have been developed
for many institutions, including major banks in Japan and Indonesia, SompoHoldings, Aioi Nissay Dowa Insurance, and Rakuten Securities, among others.
Hyperledger Iroha is already gaining traction, as Alexander Yakovlev from
Moscow Exchange Group’s National Settlement Depository, states: “We looked
for a solution that fits our requirements and is 100% open-sourced and oriented
for the specific needs of our task. Features such as Iroha’s accountmanagement and supportive community, in addition to Soramitsu’s KYC
application, were key factors in our decision to use Hyperledger Iroha for D3Ledger. Iroha’s existing adoption in several countries and the practical use casewith the Cambodian central bank were additional benefits.”
Soramitsu is using Hyperledger Iroha to build innovative, new products, such as
its Sora Identity KYC and user verification application to help financial
institutions with regulatory compliance, its Sora Pay application for
global-interbank payments, and the Sora decentralized autonomous economy,
based around the XOR token.
Soramitsu is confident that, with the release of the production version ofHyperledger Iroha V1.0, it can be a leader in blockchain commercialization, bothin Japan and worldwide. With the aim of being an open source software global
leader, Soramitsu will continue to collaborate with other Hyperledger consortium
members around the world to further the development of Hyperledger Iroha.
[About Blockchain Technology]
Blockchain (distributed ledger technology) forms the basis of distributed
applications, and can be used to safely execute generation, transmission, andreception, of digital currencies and assets on a network, without relying on acentral authority. By using blockchains it is possible to build systems that arerobust against cyberattacks, censorship, and falsification of data.
In particular, the Hyperledger Iroha blockchain is characterized by its modular,command-driven architecture, that allows developers to create complex
business logic, without writing custom code to execute on the blockchain. Thiscan be useful in creating mobile and web applications for digital asset
management, as well as performing applications that require a decentralized
digital identity.
