Hyperledger is an open source collaborative project established in conjunction with the Linux Foundation. It focuses on blockchain and other distributed ledger technologies that are ready for business use. One of the original core technologies is known as Hyperledger Fabric.
Some of its more notable member organizations include American Express, JPMorgan, IBM, ConsenSys, and Intel. Some notable general members include Alibaba Cloud, bloq, Cargill, Huawei, Microsoft, Paxos, Ripple, and Samsung.
The Hyperledger Foundation launched Hyperledger Fabric 1.0, its first blockchain, in July 2017. It included efforts by 150 developers from 28 different organizations.
Collaboration with Enterprise Ethereum Alliance
On October 1, 2018, the Hyperledger project announced that it had begun a collaborative relationship with the Enterprise Ethereum Alliance, formerly one of its biggest competitors. This move was done in the name of "bringing common standards to the blockchain space and cross-pollinate a wider open-source community," as well as foster the development of interoperability between multiple blockchains, especially enterprise-level blockchains.
In December 2018, the Hyperledger project announced Ursa, a modular library of cryptographic algorithms and other development tools that have been previously successfully implemented in blockchain-based projects. Ursa will also include an API that makes it easy for developers to understand how different cryptographic algorithms interact with each other without having to understand the underlying mathematics behind them.
Hyperledger integrates DAML
In June 2019, Hyperledger announced that it had integrated Digital Asset's Digital Asset Markup Language (DAML) with Sawtooth, as well as R3's Corda and Amazon's database service, AWS Aurora. This was done to streamline workflows around some of the world's more widely-used ledgers, according to Digital Asset CEO Yuval Rooz.
Largely at IBM's initiative, Hyperledger was established by the Linux Foundation to fulfill a similar role with blockchain technologies as the Linux Foundation. It was formed with original contributions of blockchain code from Blockstream, IBM, Ripple and Digital Asset holdings. Others among the original participants were ABN Amro, BNY Mellon, Calastone, CME Group, ConsenSys, Guardtime, Hitachi, IntellectEU, NEC, NTT Data, Red Hat and Symbiont.
