slashing

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 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.
