Hyperledger Fabric is an open-source blockchain framework designed for enterprise use. It allows organizations to create private and permissioned networks, enabling secure and efficient transactions among trusted parties. Unlike public blockchains, Hyperledger Fabric offers modular architecture, allowing developers to customize components like consensus mechanisms and smart contracts to meet specific business needs. One of the key features of Hyperledger Fabric is its support for channels, which are private communication pathways between specific network participants. This ensures that sensitive data is only shared among authorized parties, enhancing privacy and confidentiality. Overall, Hyperledger Fabric is a versatile solution for businesses looking to leverage blockchain technology.
