That’s an absolutely insane proposition.
@algol @daniel Signal has previously announced, which information the server has: "Unix timestamps for when each account was created and the date that each account last connected to the Signal service."

Feel free to check that in the client's source code.

It’s the first half of 2021 – nearly five years since the “first half of 2016” – but in many ways not much has changed. The United Kingdom is still trying to figure out Brexit, another Justin Bieber song hit #1 on the charts (is it too late now to say sorry?), and Signal still doesn’t really know...
@daniel it'll be a lot easier to convince people to use something else than signal once "everyone" has signal.
Right now "everyone" has whatsapp, and going from 1 to 2 is the hardest thing.
No one I know only has telegram, they already have at least 2 of them.
Once people have two of them, they'll be easier to get a 3rd one etc.
You cannot get diversity out of inaction.
Whatapp has not replace emails, Discord didn't replace emails or whatsapp or twitter, etc.
Signal will not replace whatsapp, even if "everyone" had signal installed.
No one went from emails to mastodon in one go.
No one will go from whatsapp to decentralised signal in one go if it existed today (it does not).
@daniel Imagine if a nonprofit could become ipso facto of communications.
I think assuming Signal advocacy being so successful that it eliminates all other communication systems is just as an insane proposition. But versus what we’re doing right now? Still better, and it means that one could advocate for even better solutions.
@lutindiscret
What do you mean with legal basis?
Signal is not named "Gatekeeper". The DSA doesn't apply to them.
Or I missed a point??
@daniel hypothetis is "Imagine your Signal advocacy is successful and we replace WhatsApp, Telegram, iMessage and Kik with Signal"
If Signal replace all thoses services, the userbase will be so huge that Signal will atrain the user count threesold abive which you become a GateKeeper according to the legal criteria. So, legally enforced interoperability with spywares.
Signal can't win.
Can matrix.org scale?
Push seems to be the problem for most messaging apps.
Is it possible to make a matrix client that can use Google services as push provider on Android, but also support independent push solutions?
And at last. Development is stale, but can a torrent based system work. (https://github.com/larsnygard/SnartNet)
Yes, I've tried it. The problem is the need for a separate push service. Snart.net is more like a Facebook, Twitter, YouTube and maybe messaging. The idea is to have the bandwidth and scaling capabilities of BitTorrent, and silly easy onboarding. Fully decentralized, and totally open.
It's both a fascinating and scary concept. I came as far as getting the BitTorrent serving to work as a PWA, but local persistent storage and Index is a bit cumbersome.
It's way above my skill level and full of AI slop, but if the concept works it may be a solution to many things.
I mean, for something to be adopted widely it should be "hey, scan my qr code with your phone, type your name and chat with me and all my contacts"
Exchange of cryptographic keys should happen in the background, and your data and keys will be backed up between yours and your close friends devices.
