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.

    Currently the App is in beta testing, I’m in the phase of trying to find people willing to stress-test it. Once the App is fully debugged my plan is to open-source it, making my GitHub public, and this is a pre-requisite for uploading the App on F-Droid.
