Recomputes every record hash from a canonical JSON representation of id, sequence, timestamp, previous_hash and payload, then checks that each record points to the hash of the record before it. If a root_hash is supplied, the same computed record hashes are folded into a deterministic binary Merkle tree with the last leaf duplicated on odd levels.
