Functions

func ConvertDuplicateVoteEvidence 

func ConvertDuplicateVoteEvidence(dupVote abci.Evidence) exported.Evidence

ConvertDuplicateVoteEvidence converts a Tendermint concrete Evidence type to SDK Evidence using Equivocation as the concrete type.

func ParamKeyTable 

func ParamKeyTable() params.KeyTable

func RegisterCodec 

func RegisterCodec(cdc *codec.Codec)

RegisterCodec registers all the necessary types and interfaces for the evidence module.

func RegisterEvidenceTypeCodec 

func RegisterEvidenceTypeCodec(o interface{}, name string)

RegisterEvidenceTypeCodec registers an external concrete Evidence type defined in another module for the internal ModuleCdc. This allows the MsgSubmitEvidence to be correctly Amino encoded and decoded.
