Are private messages end-to-end encrypted in Nostr?

Yes, private messages on Nostr are end-to-end encrypted.

The Nostr protocol uses a system of relays to transmit messages and other data between users, and it does not rely on a blockchain. Instead, it uses private and public keys for identity and message signing.

The NIP-04 protocol, which is a part of the Nostr protocol, defines the process for sending encrypted direct messages between two users[4].

Additionally, the Imp Chat mobile app, which is built on the Nostr protocol, provides end-to-end encryption for individual and group chats, ensuring that only the intended recipients can decrypt the messages[3]. Therefore, Nostr's protocol and related applications prioritize the privacy and security of user communications.

For more technical details, you can refer to the NIP-04 protocol specification on the Nostr Protocol GitHub page[5].

I think who you message isnt private though. Some metadata leakage.

If you care about #privacy you won't have the McDonald's app.

Your internet connected device is a black box.

Good morning.

How do you view Reddit on iPhone without the official Reddit app? Not website either. On Android there are many open source apps that pull from Reddit.
