Blockchain is a decentralized ledger of transactions. Each block contains a list of transactions and a hash of the previous block. Transactions are verified by network nodes through consensus mechanisms. Once added, blocks cannot be altered without changing subsequent blocks. Blockchain ensures transparency and security in data management.
