However, I'd caution that this is not the same at all as cryptographic / blockchain style tamper proofing. I can still go into the database and change things myself, or create a new one altogether.

There are some interesting ideas in the article. I.e. making a peg to a blockchain, but that won't solve the throughput / trust dilemma.
