The DID integration in my mind is orthogonal to this proposal. It will be done at the protocol level and all event kinds will benefit from it.
Discussion
Nice, I would have thought DID would have come first, but I can see the orthogonal approach. Encryption and sovereignty makes sense but privacy could become a concern.
DID is just another NIP-05 field, linking to a DID and not a website.
Yes, but then you can facilitate different identity with different medical providers and your medical data. Nostr clients have a difficult time facilitating the use of multiple accounts let alone a master controlling many identities :)
