Mind you, this is very recent and it's in the releases page of their GitHub under a pre-release. It's in the assets of the 5.3-beta release, which, now that I've checked, has packaging for MacOS, Ubuntu and AppImage. They're the ones with the *-desktop affix.

Great info, thank you!!

Yes, I think you've done a better job of explaining it than me. It's impossible, to my knowledge, to communicate without any kind of identifier, but their model is a rather ingenious one for people concerned with privacy. Couple that with onion routing, and I feel very safe talking to people on the app.

First, 🙏

Second, if you generate an entirely new key for every next message, appending it at the end of the current message, while merely depositing the message at a known place (deaddrop), while using tor (or similar), there is literally no way to link two messages without decrypting the first. That would forego any kind of identifier, but if a single message gets lost, communication entirely breaks. So, I'm no a cryptography expert, but I believe there are ways to do a similar design (mitigating the shortcomings), and eliminate identifiers entirely.

You sound more hopeful than I am, lol. But I too hope that technologies such as SimpleX take off, if only because of early adopters such as us.

Yes, maybe, but also, a sudden swing in userbase can happen, look at Reddit and Lemmy. So it is important to have good, usable software (at least moderately) ready to kick in with a sudden increase in adoption (modulo server loads, this can usually be solved with more servers). And that is IMHO where our most important role is: bringing normies to the group, getting their feedback, and relaying that feedback upstream. So that when the user rush happens, the app/platform isn't immediately cancelling the movement due to inaccessibility/poor UX.

Edit: also, something that SimpleX does is markdown editing, which is just… 👌

Yes, it is quite essential, I agree there too. Signal has formatting, but you need to use the UI to set it, and that just doesn't feel as right...
