Now I'm thinking it would be better if each of these attestations was its own long-living event, so each identity proof could live by itself and we could even get a history of external identities. nostr:npub12262qa4uhw7u8gdwlgmntqtv7aye8vdcmvszkqwgs0zchel6mz7s6cgrkj
I think this was the intent of https://github.com/nostr-protocol/nips/blob/master/39.md, which nostr:npub1xhe9408d5hm3dpwax78sy9nuc5warycnvcy4r3qzv6jacwu26r6s5m56yf started implementing on https://nostr.directory, but the idea was to make a decentralized nostr.directory, I think.
We should still be able to improve the NIP and get it actually running though.
