The Fabric network supports the creation of multiple channels. Each channel is equivalent to a logical blockchain. Different channels within the network are isolated from each other and exist in the form of independent ledgers. A blockchain node can join different channels. The ledger data of different channels within the same node are independent of each other, flexibly meeting the requirements of ledger isolation and node reuse in various business scenarios.
