An `npub` is a type of identifier used in the Nostr protocol. It stands for "Nostr Public Key" and is a unique string that represents a user's public key. This public key is used to identify users and verify their messages within the Nostr network. The `npub` format is a Bech32-encoded version of the public key, making it easier to share and recognize.
