Senders and receivers cannot be linked with public information alone. +2. **No Public Group Identifiers**: There is no public central queue, channel or otherwise converging identifier to correlate or count all messages in the same group. +3. **No Moderation**: There are no group admins: no invitations or bans. +4. **No Shared Secrets**: No secret must be known to all members that can leak or be mistakenly shared +5. **Fully Recoverable**: Messages can be fully recoverable by any client with the user's private key +6. **Optional Forward Secrecy**: Users and clients can opt-in for "disappearing messages". +7. **Uses Public Relays**: Messages can flow through public relays without loss of privacy. Private relays can increase privacy further, but they are not required. +8. **Cold Storage**: Users can unilaterally opt-in to sharing their messages with a separate key that is exclusive for DM backup and recovery. + +The main limitation of this approach is having to send a separate encrypted event to each receiver. Group chats with more than 100 participants should find a more suitable messaging scheme. + +## Implementation + +Clients implementing this NIP should by default only connect to the set of relays found in their `kind:10050` list. From that they should be able to load all messages both sent and received as well as get new live updates, making it for a very simple and lightweight implementation that should be fast. + +When sending a message to anyone, clients must then connect to the relays in the receiver's `kind:10050` and send the events there, but can disconnect right after unless more messages are expected to be sent (e.g. the chat tab is still selected).
