Why would you use a blockchain? Google “verifiable claims”. I am talking about a completely private and voluntary MECHANISM to have a way to PROVE that you went to a clinic for X and got result Y.

Right now every clinic has its own incompatible way to prove to yourself — and no one else — the results of a test you took a lot effort to get.
