how would you address relays? move everything to tor? can we do some kind of hidden service addresses for nostr too? maybe nip05 should serve as the only anchor to dns and then you can address notes as [email protected]/bookmark (and bookmarks will be listedin .well-known/nostr.json similar to relays but as a key:value pair) ? did someone already do this?
