terms, a blockchain is an immutable transaction ledger, maintained within a distributed network of peer nodes. These nodes each maintain a copy of the ledger by applying transactions that have been validated responsible for associating entities in the network with cryptographic identities. • An optional peer-to-peer gossip service disseminates the blocks output by ordering service to other peers. • Smart contracts the consensus protocol: • validates and orders transactions then propagates them to all peer nodes. • each peer then executes the transactions sequentially. The order-execute architecture can be found

It retrieves four platform-specific binaries: • cryptogen, • configtxgen, • configtxlator, • peer • orderer and • fabric-ca-client and places them in the bin sub-directory of the current working needs; from networks that are highly structured in their relationships to those that are more peer-to-peer. We’ll learn more about the Hyperledger Fabric consensus mechanisms, which currently include prior to ordering them enables each peer node to process multiple transactions simultaneously. This concurrent execution increases processing efficiency on each peer and accelerates delivery of transactions
