An anonymous and secure messenger designed to deliver messages both when the internet is available and when it is not.
You can download complied binaries from the latest release. All binaries are compiled by Github CI releases so if you don't trust to release page you can downdload them directly from CI artifacts.
The project is focused on:
- participant anonymity;
- secure message delivery;
- operation in unstable and partially unavailable networks;
- equally important online and offline-first delivery scenarios.
- transports implementation independence and different transports convergence.
- Bitmessage
- SSB (Secure Scuttlebutt)
These systems are treated as architectural and protocol references for designing transport, replication, delivery queues, and privacy.
Split into two parts:
- the core in Dart as a separate package;
- the client application in Flutter.
