Interesting...but given that "notes" (and other stuff) all goes through relays, how would Nostr keep those records private?

(I can see being able to validate the owner of a note, but not sure I'm connecting the dots on privacy...?)

Can someone school me a bit on this?

I think this would be a great idea...and could potentially get government out of your health care data...
