Functions

func GetValByIndex

func GetValByIndex(vals []*types.Validator, blockVersion uint64, idx int) *types.Validator

GetValByIndex gets the validator by index depending on tendermint version

func HashCosmosHeader

func HashCosmosHeader(header types.Header) []byte

HashCosmosHeader supports hashing both pre and post stargate tendermint block headers

func HashCosmosValSet

func HashCosmosValSet(valSet *types.ValidatorSet, blockVersion uint64) []byte

HashCosmosHeader supports hashing both pre and post stargate validator sets

func PutEpochSwitchInfo

func PutEpochSwitchInfo(service *native.NativeService, chainId uint64, info *CosmosEpochSwitchInfo)

func RegisterCodec

func RegisterCodec(cdc *codec.Codec)

func VerifyCosmosHeader

func VerifyCosmosHeader(myHeader *CosmosHeader, info *CosmosEpochSwitchInfo) error

func VoteSignBytes

func VoteSignBytes(header *CosmosHeader, valIdx int) []byte

Types

type CosmosEpochSwitchInfo

type CosmosEpochSwitchInfo struct {
	// The height where validators set changed last time. Poly only accept
	// header and proof signed by new validators. That means the header
	// can not be lower than this height.
	Height int64

	// Hash of the block at `Height`. Poly don't save the whole header.
	// So we can identify the content of this block by `BlockHash`.
	BlockHash bytes.HexBytes

	// The hash of new validators set which used to verify validators set
	// committed with proof.
	NextValidatorsHash bytes.HexBytes

	// The cosmos chain-id of this chain basing Cosmos-sdk.
	ChainID string
}
