70 Open Source Distributed Ledger Software Projects

Hyperledger Fabric is an enterprise-grade permissioned distributed ledger framework for developing solutions and applications. Its modular and versatile design satisfies a broad range of industry use cases. It offers a unique approach to consensus that enables performance at scale while preserving privacy.

Hyperledger Project is a new Collaborative Project at The Linux Foundation. The technical community is just getting started and will be adding code to the repository in the coming weeks. Check hyperledger.org for more information about joining the mailing lists and participating in the conversations.

Corda is an open source blockchain project, designed for business from the start. Only Corda allows you to build interoperable blockchain networks that transact in strict privacy. Corda's smart contract technology allows businesses to transact directly, with value.
