Definition ∞ Active Validator Threshold is the minimum number of validators needed for a Proof-of-Stake blockchain to function securely. This parameter is crucial for maintaining decentralization and consensus integrity against potential attacks. It ensures that a sufficient number of participants are validating transactions, thereby securing the network. The threshold directly impacts the network’s ability to process and finalize blocks reliably.
Context ∞ News frequently discusses the active validator threshold in relation to blockchain network security and upgrades. Adjustments to this value can significantly alter a protocol’s decentralization and overall stability. Monitoring this metric offers insight into the health and security posture of Proof-of-Stake systems. It remains a key consideration for network governance and protocol modifications aimed at optimizing performance.
