Gopherholes served from Nostr relays. Every hole is a set of signed Nostr events. Any bridge that can retrieve a relay copy can serve it.
Any npub works, published or not: profiles, notes and long-form articles are served as a virtual hole.
Traditional gopherspace works in the same box: a gopher:// URL,
or a bare host like baud.baby.
gopherkind is also a gopher client, so old-school holes render here too.
