Field notes
Discovery starts with seed relays and follows lists and monitor reports, including NIP-65, NIP-66, and BUD-03 sources. The page reports reading 3,026 user lists and shows protocol support and relay software alongside reachability data. Its Blossom test uses a small signed PNG, then fetches the file back for a SHA-256 check before deletion; the homepage reports that 20 indexed servers accept these test uploads.
