how about publishing name@domain on nostr event instead of dns nip-05? Current flow is 1. Hit the dns server 2. Get npub / relay What if dns server died? I suggest 1. Client req sign abount name@domain 2. Server sign it (with https cert) 3. Publish replaceable event that npub has it (name@domain) So client can find profile using profile focused relay even when nip-05 dns server died
