Definition
A blockchain is a distributed ledger that records transactions in linked, cryptographically secured blocks maintained by a network of nodes.
Overview
A blockchain is an append-only distributed ledger. Transactions are grouped into blocks, each referencing the previous block by hash, and validated by a consensus mechanism across independent nodes. Public blockchains such as Ethereum are open networks; private or permissioned chains restrict participation.
