NIP-05 - Mapping Nostr keys to DNS-based internet identifiers
In order to allow human-readable aliases to pubkeys (identities on #nostr) or proving association with a domain, #nip 05 defines the method for linking identity with web domains.
The critical part is to host this file on the domain you wish to prove association (not necessarily ownership) of: /.well-known/nostr.json
This JSON returns the pubkey(s) and (optionally) the preferred relays. If the pubkey returned (from the domain to which you are trying to prove association) matches the "nip05" field in a kind:0 event, then nostr clients can link the two.
