NIP-05

Human-readable identifiers

NIP-05 lets a Nostr public key be connected to a human-readable name like [email protected]. Without this, people would have to recognize each other by long public keys, which is a bit like asking everyone to memorize a bank-card number instead of a name.

The identifier does not replace your Nostr key, but it makes discovery and trust easier. When a client verifies a NIP-05 address, it is checking that the domain owner has published a file saying this name belongs to this public key.
