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 tbytes.HexBytes

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

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