Matrix system sucks because the servers are branded with domain names and the server operators have total ownership of your account.

In a network like Status or Session, you don’t need to know and don’t care who runs the node you happen to be using at a given moment.

what do you mean by ownership of account. You can migrate to other servers if you want? Or does that mean you lose your user ID which is tied to a provider/domain?

Isn't registering an account necessary to avoid impersonating? how does Status ensure a stable user ID?

It’s actually quite brilliant on Status.

Everyone gets a random super long number for an ID. Your friends can assign your name when they add you as a contact (just like phone numbers). And then you can also get a globally recognizable name like ENS domains if you want to pay a little. It’s like a vanity plate on a car.

but what prevents me from using your ID? I'm guessing something like a blockchain.

It’s just a random keypair. You can’t use my ID because you would only see my public key.
