You can have multiple set up but the one in your kind 0 metadata event (your profile data) is the only one that clients pay attention to.
Is there any reason that a Nostr profile can’t have multiple NIP-05s? Multiple domain verifications?
Discussion
I can think of multiple reasons that I’d want to have multiple set up and working.
Do you think it would be technically possible to have that metadata be one or many instead of just one? Or was it intentionally limited to just one?
I'd actually love to hear more about the reasons for having multiple NIP-05 verifications. For the most part, I think NIP-05 is sort of a shitcoin. It's fairly meaningless and lives outside the actual protocol so it can only sort of be trusted.
It's not technically possible to list multiple, I mean, I guess you could put multiple values in the one NIP-05 field but most clients would just puke when trying to understand it.
I think of NIP-05 basically like how attestations worked in the original Iris (cc nostr:npub1g53mukxnjkcmr94fhryzkqutdz2ukq4ks0gvy5af25rgmwsl4ngq43drvk ) except it can also help your account be to be more discoverable.
Maybe I get an NIP5 from my church, my gym, and my hometown.
Each of these would not only attest my profile as someone that is “known” and (at least somewhat) trustworthy, but it would also help to increase the findability of my profile.
Now it could be that this is better solved by a different method and NIP5 should just go away. Maybe this can be solved by my church, gym, and hometown each just running exclusive relays (write for members, read for all?) and NIP5 usernames aren’t needed?
But if someone can know me by multiple usernames, I think that does help with the discoverability aspect.
