The hash function in Git is a cryptographic hash. The reason that Git is not a Blockchain has nothing to do with its choice of hash function. Rather a Blockchain has a procedure through which nodes decide what successor is acceptable, Git doesn't care it allows all successors. Kafka has a procedure for consensus which determines who can declare what the successor is.
