Syrinx

What is Syrinx?

Syrinx is a censorship-resistant communications platform for closed communities. It operates as a federated network where content, called reeds, lives on members devices rather than central servers. The system uses a tracker relay model similar to BitTorrent, meaning the server only knows who has a post, not what the post contains. All content is encrypted before leaving the sender device and verified by clients using OpenPGP signatures.

The platform emphasizes user control and community independence. Servers can run on modest hardware like a Raspberry Pi, and deployment scripts are provided for home networks. Federation allows separate communities to connect without relying on a single provider. Admin actions are recorded in a public ledger that every member can review, and administrators require mutual approval for administrative changes.

The desktop application works offline and caches data locally, allowing users to continue interacting even if the server goes down. If a domain is seized, communities can migrate to new domains while preserving their cryptographic identity. The project is currently a proof of concept with planned features including account migration and private messaging.
