Open Source For You
|May 2025
Explore the key features and use cases of Hyperledger Fabric, the open source blockchain framework for enterprises. Then learn how to get started with it.
-
Hyperledger Fabric is an open source blockchain framework designed specifically for enterprise solutions. It is part of the broader Hyperledger project, which is hosted by the Linux Foundation and aims to advance cross-industry blockchain technologies. Unlike public blockchains such as Bitcoin or Ethereum, Hyperledger Fabric is a permissioned blockchain, meaning that it allows only authorised participants to join the network. This feature provides a more controlled environment for businesses, making it particularly suitable for industries that require strict compliance and security measures.
Key features of Hyperledger Fabric
Modular architecture: One of the standout features of Hyperledger Fabric is its modular architecture. This design allows organisations to plug in their preferred components, including consensus algorithms, membership services, and smart contract languages. This modularity enables customisation based on specific business needs, allowing companies to tailor the blockchain framework to fit their operational requirements.
Permissioned network: Hyperledger Fabric operates as a permissioned network, where participants are known and authenticated. This enhances security and privacy, making it particularly important for enterprises that handle sensitive data and require compliance with regulations such as GDPR or HIPAA. The permissioned nature of the network allows organisations to control who can access the blockchain and what data they can see.
Smart contracts (chain code): In Hyperledger Fabric, smart contracts are referred to as chain code. These contracts define the business logic of applications and can be written in various programming languages, including Go, Java, and JavaScript. This flexibility makes it accessible to a wide range of developers and allows organisations to leverage existing programming skills within their teams.
