Slashing refers to punishment for misbehavior within PoS systems. The degree of the punishment as well as what classifies as misbehavior is defined individually for each protocol. In general, slashing results in parts of a validators stake being burned or forfeited. In some protocols, not only the validators' own funds but also delegated stake can be subject to slashing. Slasing is implemented to incentivize validators for availability, security and participation.
