Method Hash

types/block.go:440–475

Hash returns the hash of the header. It computes a Merkle tree from the header fields ordered as they appear in the Header. Returns nil if ValidatorHash is missing, since a Header is not valid unless there is a ValidatorsHash (corresponding to the validator set).
