## `chat2` message protobuf format
Each `chat2` message is encoded as follows
```protobuf
message Chat2Message {
uint64 timestamp = 1;
string nick = 2;
bytes payload = 3;
}
```
where `timestamp` is the Unix timestamp of the message, `nick` is the relevant `chat2` user's selected nickname and `payload` is the actual chat message being sent. The `payload` is the byte array representation of a UTF8 encoded string.
