It seems to me that a better solution for auditing in situations where you don’t need a distributed ledger is using event sourcing. Blockchains are just a data structure after all. You wouldn’t say “just use a b-tree.” Event sourcing databases solve most of the problems blockchain companies seem to think they have. (And the other problems they have probably won’t be solved with Blockchain anyway.)
