Definition ∞ A validator response refers to the action or data submitted by a validator node within a proof-of-stake or similar consensus mechanism in reaction to network events. This includes proposing new blocks, attesting to the validity of transactions, or participating in voting processes. The timeliness and correctness of these responses are critical for maintaining network security and finality.
Context ∞ Validator response is a key performance indicator and security consideration in proof-of-stake blockchains. News often discusses validator performance, slashing penalties for incorrect responses, or network upgrades that aim to optimize validator participation and ensure network health.
