Sure. Which is, as the parent comment pointed out, rarely one of the things people trumpeting "blockchain" need in the problem domain they're proposing to deploy it. I don't need global PoW or PoS consensus for my health records. I need something my health providers and I can agree is authoritative and as accurate as the data entry makes possible. The parent comment's "immutable, distributed, cryptographically-verified database". Something like a shared git repo. Not like a crypto currency.
