Hyperledger incubates and promotes a range of business blockchain technologies, including distributed ledger frameworks, smart contract engines, client libraries, graphical interfaces, utility libraries and sample applications. The Hyperledger greenhouse strategy encourages the re-use of common building blocks and enables rapid innovation of DLT components. 

Distributed Ledgers

Hyperledger Besu is an open source Ethereum client developed under the Apache 2.0 license and written in Java. It can be run on the Ethereum public network or on private permissioned networks, as well as test networks such as Rinkeby, Ropsten, and Görli.

Hyperledger Cello aims to bring the on-demand “as-a-service” deployment model to the blockchain ecosystem to reduce the effort required for creating, managing and terminating blockchains.

» Learn More

Hyperledger Explorer can view, invoke, deploy or query blocks, transactions and associated data, network information, chain codes and transaction families, as well as any other relevant information stored in the ledger.

Significant Open Source software projects must offer developers and end users more than a simple repo, mailing list, and website. Hyperledger, a Linux Foundation Project, offers maintainers the following benefits:

Foundation

As a Linux Foundation project, Hyperledger provides maintainers and their communities direct access to one of the deepest open source brain trusts in the world to help with everything from licensing to governance to release management to ecosystem development. In other words, we let you focus on developing the technology, confident that the legal, technical and organizational infrastructure your project needs for the long run is in place.

Staff

  • Hyperledger leaders bring decades of experience developing and growing transformative open source infrastructure software
  • You and your community will have access to dedicated PR, events and marketing resources to reach the audiences that matter (developers, end users, members) with the right messages. You will be able to plug into our web site and blog, which receive nearly 50,000 unique visitors per month as well as other high-impact promotional programs.

Events

  • Hyperledger has an extremely active industry conference calendar and project leaders are encouraged to participate.
  • So far, Hyperledger has hosted 8 hackfests, averaging 150 attendees – this is a great way to tap into the existing Hyperledger developer community to improve your project and reach new developers.
  • Hyperledger is also active with its own and other hack-a-thon competitions to draw developer attention to our projects.
