This project is a Graduated Hyperledger project. For more information on the history of this project, see the Fabric wiki page. Information on what Graduated 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.
Fabric provides periodic releases with new features and improvements. Additionally, certain releases are designated as long-term support (LTS) releases. Important fixes will be backported to the most recent LTS release, and to the prior LTS release during periods of LTS release overlap. For more details see the LTS strategy.
Current LTS release:
Historic LTS releases:
- v2.2.x (maintenance ended in February 2024 with the delivery of v2.2.15)
- v1.4.x (maintenance ended in April 2021 with the delivery of v1.4.12)
Unless specified otherwise, all releases will be upgradable from the prior minor release. Additionally, each LTS release is upgradable to the next LTS release.
Fabric releases and release notes can be found on the GitHub releases page.
