Abstract
x/evidence
is an implementation of a Cosmos SDK module, per ADR 009,
that allows for the submission and handling of arbitrary evidence of misbehavior such
as equivocation and counterfactual signing.
The evidence module differs from standard evidence handling which typically expects the underlying consensus engine, e.g. Tendermint, to automatically submit evidence when it is discovered by allowing clients and foreign chains to submit more complex evidence directly.
All concrete evidence types must implement the Evidence
interface contract. Submitted
Evidence
is first routed through the evidence module's Router
in which it attempts
to find a corresponding registered Handler
for that specific Evidence
type.
Each Evidence
type must have a Handler
registered with the evidence module's
keeper in order for it to be successfully routed and executed.
Each corresponding handler must also fulfill the Handler
interface contract. The
Handler
for a given Evidence
type can perform any arbitrary state transitions
such as slashing, jailing, and tombstoning.
