Hyperledger Fabric is an implementation from blockchain framework, hosted by the Linux Foundation. It is an open source enterprise-grade permission that makes use of distributed ledger technology. It is a platform that deploys blockchain networks with the platform providing smart contracts, the ledger, and providing a consensus between the members through maintenance of the Fabric protocols. Fabric is designed for use by businesses with the blockchain itself being operated by a set of known participants. These participants are re-identified and vetted through a concept called the permission blockchain. The blockchain also provides a way of securing an interaction among a group of entities who know each other and have common business interests. These entities are interested in managing a decentralized network instead of turning the management of their ledgers to one party. Through reliance on the identities and peers, the blockchain can use the traditional crash fault tolerant or the Continue reading
