Martti recently implemented something very cool on iris.to to improve privacy over Nostr DMs.
Last year I wrote something that could be useful in that field: https://github.com/eddieoz/nostr-stealth
It features:
- Metadata Encryption: Sender and receiver metadata is securely encrypted to ensure complete anonymity.
- Channel Mixer: The destination for each message is always the channel. By design, this ensures the real receiver remains undiscoverable.
- Ephemeral Keys: Every message sent uses ephemeral keys, ensuring that tracking a message back to its sender becomes an impossible task.
The main idea is to ensure sender and receiver metadata full anonymity and make use of channel mixers to ensure that individual messages between users cannot be distinguished or differentiated.
