A nice place to discuss rumors, happenings, innovations, and challenges in the technology sphere. We also welcome discussions on the intersections of technology and society. If it’s technological news or discussion of technology, it probably belongs here.

Remember the overriding ethos on Beehaw: Be(e) Nice. Each user you encounter here is a person, and should be treated with kindness (even if they’re wrong, or use a Linux distro you don’t like). Personal attacks will not be tolerated.

We estimate that by 2025, Signal will require approximately $50 million dollars a year to operate—and this is very lean compared to other popular messaging apps that don’t respect your privacy.

No, P2P = Peer to peer, meaning no servers are required in between.

Wouldn’t that mean both have to have a connection at the same time? What if one is offline?

Yes.

What if one is offline?

How do you think you're going to receive messages offline?

How much time does your phone spend offline?

One device can send a receipt when received. If the other device doesn't receive that receipt it can just keep pinging periodically until it receives it.

You can also just hook up any old phone or computer, install the app, and let it run as the server.
