It’s the closest NIP (NIP-58) for attestations, where an issuer attests something is true about a recipient.
Discussion
I have a use case for this actually.
Prove that someone lives in a certain area. Mail a code to someone and they enter the code they were mailed, then they get the attestation that they live in a city or state etc. Could do this process once a year to verify.
Then stuff like civil discourse becomes much more meaningful. No bots or people from other locations chiming in.
