Block

Definition of "Block"

A block is a package of data that contains zero or more transactions, the hash of the previous block (“parent”), and optionally other data. The total set of blocks, with every block except for the initial “genesis block” containing the hash of its parent, is called the blockchain and contains the entire transaction history of the network. Note that some blockchain-based cryptocurrencies instead use the word “ledger” for a blockchain; the two are roughly equivalent, although in systems that use the term “ledger” each block generally contains a full copy of the current state (e.g., currency balances, partially fulfilled contracts, registrations) of every account, allowing users to discard outdated historical data.
