Source on Matrix being "based on signal encryption protocol?" I'm pretty sure that's wildly incorrect

I went digging for information on this because somewhere in my mind this claim was installed as true, but your skepticism re-activated my skepticism.

It seems that the Matrix protocol offers optional end-to-end encryption on a room-by-room basis via Double Ratchet Algorithm that was introduced by the Signal Protocol [0]. This is the academic paper that Wikipedia cites for that claim [1].

[0] https://en.m.wikipedia.org/wiki/Signal_Protocol#Influence [1] https://link.springer.com/chapter/10.1007/978-3-319-45982-0_...

So it uses a part of the Signal protocol. That is interesting, and I did not know that, but that does not mean it uses the Signal protocol in its entirety.

He was talking about the encryption of the Signal eptocol, which explicitly doesn't include stuff like message format.

The core idea of the signal protocol is the ratcheting algorithm, which provides the actual qualitative security benefits, this the only real important thing.

Also he was explicitly stating it is based on it, I feel like you are arguing just, because you were so sure yet so wrong in your previous comment

I see, okay, I suppose you guys are probably right.

I was only "pretty sure" in my original comment, not "so sure!" :)
