Being different from the public blockchain, Hyperledger Fabric is a permission-based blockchain network. Here, the identity of each node is known and all participants know each other. Since all nodes can trust each other, mining power is not required in order to build trust. This allows us to select various consensus mechanisms, such as the BFT protocol. In the permission blockchain, more centralized identity management prevents Sybil attacks. Participants in the network can transfer, query, and invoke transactions that are controlled by the chain code. Enterprise applications often require complex enterprise security standards. A permissioned network is highly suitable for this scenario.
