The reason we emphasize the additional message in MLS is because we use postage to solve spam issues, so an extra message means users have to pay for an extra stamp. 

The MLS protocol is very complex, and we need a lot of time to understand it; we haven’t started working on MLS groups yet. Next week, Keychat will support both small and medium groups. Perhaps the medium group will eventually be replaced by a large group based on MLS. Much of what we are doing now is experimental, since Keychat hasn’t been added to the app stores yet, and we can continue to experiment. 

 If you’re asking about the spec for Keychat’s one-on-one chats, we haven’t written it yet. However, the code has already been open-sourced. Regarding one-on-one messages, we want to emphasize that although the nostr protocol and Signal protocol use different encryption suites, when we encrypt messages using the Signal protocol, we do not alter any encryption suites.”
