A blockchain is a type of digital ledger where transactions grouped into blocks are replicated across a network of participants. Blockchains can enable a decentralized ledger system of transactions which do not rely on any central authority or trusted third parties for transaction validationtransaction validation. All participants in the peer-to-peer network are known as nodes, and maintain a full record of all transactions on the blockchain communicating directly following a protocol that forms a distributed consensus on the next valid block in the chain.
