	// ErrNoProposerAddress is returned when the proposer address is not set.
	ErrNoProposerAddress = errors.New("no proposer address")

	// ErrLastHeaderHashMismatch is returned when the last header hash doesn't match.
	ErrLastHeaderHashMismatch = errors.New("last header hash mismatch")

	// ErrLastCommitHashMismatch is returned when the last commit hash doesn't match.

	// ErrAggregatorSetHashMismatch is returned when the aggregator set hash
	// in the signed header doesn't match the hash of the validator set.

var InitStateVersion = cmstate.Version{
	Consensus: cmversion.Consensus{
		Block: version.BlockProtocol,
		App:   0,
	},
	Software: version.TMCoreSemVer,
}

InitStateVersion sets the Consensus.Block and Software versions, but leaves the Consensus.App version blank. The Consensus.App version will be set during the Handshake, once we hear from the app what protocol version it is running.
