Stores and verifies the entire chain: downloads every block, validates every transaction.

A validator is a full node + signing authority; an RPC node is a full node + exposed API.

"Full" distinguishes from light clients (which only fetch headers). Besu nodes are always full.

Every node in a private IBFT/QBFT network is a full node by default. The distinction matters more in public chains.
