I am not nearly as up on the tech as you and @MoonSong are, so much so that I was thinking of "Blockchain" as a generic, when it's actually a specific bit of software.Blockchain isn't even good for that. Unless you want have to patient data be re-identifiable, you'd have to go with a centralized, private blockchain, and private blockchains have none of the advantages of blockchain tech, which by nature is entirely about the advantages of public, decentralized databases.
Please, don't believe the hype. We spent four months straight researching and interview experts about this stuff at my job. Crypto is the only "valid" use of blockchain tech, and we all know how awesome and not-scammy crypto is.
I do think there's a use case for decentralized secure data. I can imagine a future where we fight back against deepfakes, for instance, by having the history of those files spelled out for everyone to see. But we're not at that point yet (I don't think industrialized societies yet realize how much of a problem deepfakes are about to be) and I certainly don't trust any of the crypto-bros to be part of any real solutions to problems they didn't invent themselves.
