A blockchain is a distributed, append-only ledger replicated across a peer-to-peer network of nodes — no single server owns it, and past records cannot be altered without redoing all subsequent work. Each block contains a cryptographic hash of the previous one, chaining them into a tamper-evident history. Transactions are validated by consensus rather than a central authority, which means settlement is transparent and globally verifiable.
