block

A block is where transactions or digital actions are stored. Once a block is full, it gets linked to the previous one, creating a chain of blocks or a "blockchain".

A block is a bundled unit of information that includes an ordered list of transactions and consensus-related information. Blocks are proposed by proof-of-stake validators, at which point they are shared across the entire peer-to-peer network, where they can easily be independently verified by all other nodes. Consensus rules govern what contents of a block are considered valid, and any invalid blocks are disregarded by the network. The ordering of these blocks and the transactions therein create a deterministic chain of events with the end representing the current state of the network.
