Npub and nprofile are both ways to represent user identities in Nostr, but they have different purposes:

npub
• This is your public key.
• It starts with npub1...
• It’s a unique identifier for your account.
• People use this to find or follow you.
• It only contains your public key, nothing else.

nprofile
• This is a more detailed version of your identity.
• It starts with nprofile1...
• It includes your public key plus extra info like which relays you use.
• This makes it easier for apps to find your data on the network.
• It’s basically a “contact card” with more context than just the public key.

In short:
• npub = just your public key (like a username).
• nprofile = public key + relay info (like a full contact).
