I have been working on an Android App quite a while now, starting from a simple idea.

A messenger where messages travel directly between phones with no servers in between. Using direct WebRTC encrypted connections (SRTP/DTLS), there are no servers that stores, reads, or relays content. Group chats use a gossip protocol where members relay to other members.

The only infrastructure the app touches is a signalling relay to set up the connection (no message content), a push notification to wake up a sleeping phone (also no content), and a TURN relay for restricted networks (encrypted packets only).

I wrote a detailed white paper explaining the full architecture: https://www.mindtheclub.com/white-paper.html

The app is in Open Testing on Google Play (1,000 tester cap): https://www.mindtheclub.com/beta-signup.html

I’m interested in this community's perspective on whether the architecture holds up.

I agree, is actually quite high level, describing the main architecture and functionality`. What I intend to do, once the code is fully debugged, is to make my GitHub public, and upload a more detailed technical doc there. I thought not to make a public landing page, that targets a broader audience, too technical. In the meantime I'm happy to respond to any kind of technical question.
