Hyperledger Fabric is part of LF Decentralized Trust, which expanded from Hyperledger Foundation into the Linux Foundation's flagship organization for decentralized trust technologies.

LF Decentralized Trust brings together the full Hyperledger ecosystem, Trust Over IP, Hiero, and a growing landscape of ledger, identity, interoperability, cryptographic, privacy, smart contract, and integration projects.

The Hyperledger Fabric name continues as an important project brand within LF Decentralized Trust. 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, offering a unique approach to consensus that enables performance at scale while preserving privacy.

This GitHub organization preserves the Hyperledger namespace and hosts the repositories for Hyperledger Fabric's core platform, SDKs, chaincode libraries, tooling, samples, and documentation, while the current foundation identity, governance, and broader project landscape are represented by LF Decentralized Trust.

The governance repository is the home of LF Decentralized Trust TAC processes, policies, programs, and meeting minutes. These materials can also be viewed at:

https://lf-decentralized-trust.github.io/governance/

The LF Decentralized Trust Landscape provides an overview of projects, technologies, members, and ecosystem participants across the broader decentralized trust community, including Hyperledger Fabric. It can be viewed at:

This is the GitHub organization for Hyperledger Fabric. It is designed to serve as an entry point to the project and a guide to all its repositories and resources.

Hyperledger Fabric is a Graduated project under the Hyperledger umbrella. It provides a modular architecture with high levels of confidentiality, resiliency, flexibility, and scalability. Hyperledger Fabric allows for pluggable implementations of various components, accommodating the complexities of different economic ecosystems.

Hyperledger Fabric provides periodic releases with new features and improvements. Certain releases are designated as Long-Term Support (LTS), ensuring that important fixes are backported during overlap periods.

Hyperledger Fabric is an enterprise-grade permissioned distributed ledger framework. It is designed for use in developing solutions and applications across a broad range of industry use cases.

Key characteristics include:

• Modular architecture — Pluggable consensus, membership services, ledger storage, and chaincode execution.
• Permissioned network — All participants have known identities, enabling regulatory and compliance use cases.
• Confidential transactions — Channels and private data collections enable data isolation between participants.
• Smart contracts (chaincode) — Business logic written in Go, Java, or Node.js, executed in isolated containers.
• Performance at scale — Execute-order-validate architecture separates transaction execution from ordering for high throughput.
• Enterprise readiness — BFT and Raft consensus, certificate authority integration, and LTS release support.
