x/slashing

Abstract

This section specifies the slashing module of the Cosmos SDK, which implements functionality first outlined in the Cosmos Whitepaper (opens new window) in June 2016.

The slashing module enables Cosmos SDK-based blockchains to disincentivize any attributable action by a protocol-recognized actor with value at stake by penalizing them ("slashing").

Penalties may include, but are not limited to:

• Burning some amount of their stake
• Removing their ability to vote on future blocks for a period of time.

This module will be used by the Cosmos Hub, the first hub in the Cosmos ecosystem.
