I’m really excited about the idea of someone deploying encrypted DMs on this thing. Need a good plan for key distribution and identity binding (makes me sad Keybase got eaten by Zoom, oops) and then the rest is just Signal protocol?
I love saying things like “then the rest is just…” :)
The two things applied crypto needs in general:
1. Good, reliable identity/key binding and key transparency.
2. Hardware-backed key storage with MPC aimed at consumers, for protecting keys with passwords.
I feel like Keybase got a lot of the way there on (1) but never quite got the whole system running. (2) doesn’t exist yet.
@matthew_d_green Funnily enough a lot of cryptocurrency startups are trying to do 2 to some extent. Would be interesting to see some of the applied work there be used for different contexts.
