This is one place where blockchain is actually useful. No one entity is responsible for the integrity of the "ledger". Of course it wouldn't be publicly writable so not exactly like the blockchains you normally think of.
I can't see how the blockchain would be particularly useful here either. The security features of the blockchain come at the cost of extreme energy usage. Storing documents using simple public-private key cryptography is waaaay more than enough imo.
You don't have to "mine blocks" to have a blockchain. It's just a continual list of transactions that can't be modified after the fact. So a hacker couldn't wipe out your existence from the chain without controlling the majority of the participants (in a consensus algorithm). Not saying it's an ideal use-case but highlighting that feature. There are many ways to avoid "data wipe" attacks.
So they are immutable basically.
Crypto fellaz always forget that we actually have this solution in most databases, and it's called write-ahead-log.
