Here again:
quoting nevent1q…eta2Have you seen naddr1qv…sfkc?
It's implemented now in Jumble, Yakihonne, Imwald, Hallway, https://github.com/fiatjaf/window.nostr.js, Nostrord and other places. In my experience it works well enough to be used by anyone and solves every concern under the sun.
The only problem that remains is how to do NIP-17 DMs with it, but the Jumble/Coop approach of having a special key only for DM encryption that doesn't go on the bunker seems to be a good enough compromise. I think it's being implemented in Nostrord too now.
DMs are really a very hard issue I wish we didn't have to do (ideally people should just use other protocols, like Simplex or Delta).
