After being nerd sniped by hearing nostr:npub1az9xj85cmxv8e9j9y80lvqp97crsqdu2fpu3srwthd99qfu9qsgstam8y8 mention OTR for the millionth time on the Bitcoin Review podcast, I spent the last few weeks digging into OTR, the Signal protocol, and a grab-bag of other cryptography.

The end result is that I (am pretty sure at least) that I found a way to do E2EE (end-to-end encrypted) DMs on Nostr in a way that is both forward and post-compromise secure AND doesn't require any centralized servers.
