Slashing module specification

Abstract

This section specifies the slashing module of the Cosmos SDK, which implements functionality first outlined in the Cosmos Whitepaper 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 "slashing" them: burning some amount of their stake - and possibly also 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.
