Hyperledger Fabric: Enterprise permissioned blockchain framework

Hyperledger Fabric is an open-source blockchain framework developed under the Linux Foundation's Hyperledger project for building enterprise-grade distributed ledger applications. The platform uses a modular architecture with pluggable components including consensus algorithms, membership services, and smart contract execution environments. It operates as a permissioned network where participants are known and authenticated, supporting private channels and confidential transactions between specific network members. The framework is commonly used for supply chain tracking, financial services, healthcare records, and other enterprise use cases requiring auditability and privacy.
