Quorum

A quorum is the minimum number of participants that must agree before a decision or transaction is treated as final. In blockchain systems the term appears in several places: a proof-of-stake network may require a quorum of validators to attest to a block, a multisig wallet needs a quorum of signers, for example three of five keys, before funds can move, and a DAO vote fails if turnout does not reach the quorum set in its governance rules. Quorum rules trade speed for safety. A low threshold makes decisions easy but concentrates control, while a high one resists capture yet can stall the system when enough participants are offline or unwilling to sign.
