Definition ∞ Validator slashing is a penalty mechanism in Proof-of-Stake blockchains that removes a portion of a validator’s staked assets. This punitive action is triggered when a validator acts maliciously, such as signing conflicting blocks, or fails to uphold network responsibilities, like prolonged offline periods. The purpose of slashing is to deter undesirable behavior and uphold the integrity and security of the network’s consensus process. It serves as a critical economic disincentive for validators to deviate from protocol rules.
Context ∞ News about validator slashing frequently surfaces during discussions of network security, validator performance, or protocol upgrades that modify slashing conditions. Instances of slashing can impact market sentiment and validator reputation, especially for large staking pools. The severity and frequency of slashing events are key indicators of a Proof-of-Stake network’s robustness and economic security.
