Quorum Size

Definition

Quorum size refers to the minimum number of participants or votes required in a distributed system to authorize an action, reach a consensus, or validate a transaction. This threshold is critical for maintaining system integrity and preventing malicious actors from unilaterally controlling the network. In blockchain protocols, particularly those using proof-of-stake or delegated consensus mechanisms, a predefined quorum ensures sufficient decentralization and security. It directly influences the system’s resilience against attacks and its operational efficiency.
