Depends on how the database and application was set up. In a properly formed ZK application you cannot obtain any reasonable information by brute force hashing names. Edit: I realize you’re probably talking about Callisto which does seems like simple hashing of names, but I wanted to note that this is not always the case in apps using ZK proofs and FHE which the article touches on a bit later.
