Hyperledger Fabric

Note: This is a read-only mirror of the formal Gerrit repository, where active development is ongoing. Issue tracking is handled in Jira.

This project is an Active Hyperledger project. For more information on the history of this project see the Fabric wiki page. Information on what Active entails can be found in the Hyperledger Project Lifecycle document. Hyperledger Fabric is a platform for distributed ledger solutions, underpinned by a modular architecture delivering high degrees of confidentiality, resiliency, flexibility and scalability. It is designed to support pluggable implementations of different components, and accommodate the complexity and intricacies that exist across the economic ecosystem.

Hyperledger Fabric delivers a uniquely elastic and extensible architecture, distinguishing it from alternative blockchain solutions. Planning for the future of enterprise blockchain requires building on top of a fully-vetted, open source architecture; Hyperledger Fabric is your starting point.
