Hyperledger Wraps up 2016 By Welcoming Eight New Members

By | Announcements

Diverse set of new members joins fastest growing open blockchain initiative

SAN FRANCISCO, CA – (December 28, 2016) – Hyperledger Project, a collaborative cross-industry effort created to advance blockchain technology, announced today that eight new members have joined the project to help create an open standard for distributed ledgers for a new generation of transactional applications. Last month, Hyperledger announced it reached 100 active members in less than one year, a huge milestone for the open source project, hosted by The Linux Foundation.

“This year has been full of growth for the project,” said Brian Behlendorf, Executive Director, Hyperledger. “Not only did we exceed 100 members, Hyperledger met significant development milestones thanks to the community’s hard work. As 2016 was a year of exploration, R&D and prototyping, we’re excited for 2017 to be the year we start to see case studies of the technology in production environments.”

Hyperledger aims to enable organizations to build robust, industry-specific applications, platforms and hardware systems to support their individual business transactions by creating an enterprise grade, open source distributed ledger framework and code base. The latest members include: CA Technologies, Factom Foundation, Hashed Health, Koscom, LedgerDomain, Lykke, Sovrin Foundation and Swisscom.

Hyperledger Welcomes Iroha

By | Blog, Hyperledger Iroha

iroha_3

We’re pleased to announce that the distributed ledger project, Iroha, has been accepted into incubation status under Hyperledger. Originally developed by Hyperledger member company, Soramitsu, Iroha was inspired by the Fabric architecture and aims to provide a development environment where C++, web, and mobile application developers can contribute to the Hyperledger Project.

What is Iroha?

Iroha seeks to complement Fabric, Sawtooth Lake, and other potential projects, by creating reusable components in C++ that can be called from languages such as Go. In this way, Iroha is additive to existing projects and the long term goal is to realize a robust library of reusable components that can be selected and used freely by those running distributed ledgers on Hyperledger technology.

“Iroha allows even more developers to interact with Hyperledger to build infrastructural projects and applications requiring distributed ledger technology,” said Brian Behlendorf, Executive Director of Hyperledger. “It is encouraging to see member companies actively contributing to a diverse and sustainable open source blockchain ecosystem built on cooperation.”

The design and architecture of Iroha is greatly inspired by Fabric, in that blockchain and chaincode services form the overall architecture. Where possible, APIs were made to be similar to Fabric and, rather than competing with Fabric, the goals of Iroha are to:

  1. Provide an environment for C++ developers to contribute to Hyperledger
  2. Provide infrastructure for mobile and web application support
  3. Provide a framework to experiment with new APIs and consensus algorithms that could potentially be incorporated into Fabric in the future.

Why Iroha?

Currently, the Hyperledger Project lacks an infrastructure project written in C++, thus limiting the potential developers who can contribute. Also, there is not currently a strong focus on user interaction or mobile applications, though both are necessary for the realization of the widespread use of distributed ledger technology. Iroha aims to rectify both of these points, bringing in more developers while providing libraries for mobile user interface development.

Iroha is a distributed ledger project that was designed to be simple and easy to incorporate into infrastructural projects requiring distributed ledger technology. Iroha features:

  1. Simple construction
  2. Modern, domain-driven C++ design
  3. Emphasis on mobile application development
  4. New, chain-based Byzantine fault tolerant consensus algorithm, called Sumeragi

Although turing complete smart contracts are available via chaincode in Java (running a sandboxed JVM), users do not need to write chaincode in order to define digital assets in Iroha. Common use cases, such as deploying new currencies and sending text messages, are available as part of the core framework. Iroha is composed of the following:

  • Iroha core
  • Iroha Native iOS Library
  • Iroha JavaScript Library
  • Iroha Native Android Library

Iroha core provides the distributed ledger infrastructure comprising the data membership services, consensus algorithm, peer-to-peer network transmission, data validation, and chaincode infrastructure. The iOS, Android, and JavaScript libraries provide convenience functions for performing common operations, such as digitally signing transactions. Future work will expand these common functions to interoperate with the Fabric ledger.

Who will work on Iroha?

Soramitsu has committed several full time engineers to the project. Makoto Takemiya of Soramitsu is the initial project maintainer, along with six other engineers at Soramitsu. Besides Soramitsu, the co-sponsors of the proposal and other Hyperledger members are considering committing resources to work on Iroha including Toshiya Cho of Hitachi, Takahiro Inaba of NTT Data, and Mark Smargon of Colu.

Soramitsu is also doing collaborative research with The University of Tokyo, The University of Aizu, and Center for Global Communications (GLOCOM, below) of International University of Japan. From the University of Tokyo, Hideyuki Tanaka will consider economics use cases with Iroha. From The University of Aizu, Yasushi Fujii will explore business use cases with Iroha. From GLOCOM, Soichiro Takagi will consider economics and scientific research using Iroha.

“We’re pleased that Iroha has been accepted for incubation into  Hyperledger,” said Makoto Takemiya at Soramitsu. “By creating C++, mobile, and web development environments for Hyperledger, new developers can join the project and help contribute not only to Iroha, but to other sub projects, such as Fabric and Sawtooth Lake.”

Learn more about Iroha

Working with community members and use case partners, we would like to continue to improve upon Iroha and have it reach and active project stage in the future. The end goal is to realize a suite of components that can be freely interoperable with other Hyperledger projects.

The following repositories on github have been created to manage Iroha resources:

  • https://github.com/hyperledger/iroha
  • https://github.com/hyperledger/iroha-ios
  • https://github.com/hyperledger/iroha-android
  • https://github.com/hyperledger/iroha-javascript

Hyperledger Hackathon and Hackfest Recap

By | Blog

The first ever Hyperledger Hackathon took place October 1-2 in Amsterdam. More than 120 developers (20 teams) gathered for the event organized by ABN AMRO, IBM, Holland Fintech and Hyperledger.

During the Hackathon, teams of students, fintechs, start-ups, and staff from IBM and ABN AMRO had 36 hours to build their own application on Hyperledger. As part of their efforts, they were allowed to tap the expertise of  visiting experts from the Hyperledger Technical Steering Committee and others. At the end of the 36-hour period, a jury assessed the teams’ proposals and applications with a focus on application value to clients and business as well as its technical implementation.

The energy and enthusiasm of the teams was incredible to watch. Each team had a deep appreciation of the technology and how it could be applied. A few of the teams even slept at the venue, working through the night to polish their implementation and pitch!

The winning team (pictured below) built a practical application for the storage of medical information, controlled and updated by medical experts and patients as owners of the data. Each team member won an Oculus Rift.

Following the Hackathon was the Hyperledger Hackfest, which took place on October 3-4 in the ABN AMRO Innovation Centre. 60 developers attended. This marked the first time the bi-monthly international Hackfest was held in Europe.

Some of the agenda items addressed at the event included:

  • Overview of consensus model evolution
  • Data confidentiality enhancements (selective distributed ledger)
  • Future support for other chaincode languages
  • Starter kit tutorial
  • Brian and Chris held a session for our ABN AMRO hosts on what the Hyperledger project is all about
  • Brian held a session on new potential projects
  • There were a number of ad hoc breakouts with various maintainers present (Chris, Gari, Binh, Murali, Tamas and Gabor)
  • Fabric maintainers held a meeting to discuss release process
  • Hyperledger Architecture WG also held a session at the Hackfest, led by Ram Jagadeesan from Cisco
