The Tor BSD Diversity Project (TDP) is an initiative which extended the use of the BSD Unix operating systems in the Tor public anonymity network.
In a global anonymity network, monocultures are potentially disastrous. A single kernel vulnerability in GNU/Linux impacting Tor relays could be devastating. The project helped foster a stronger Tor network through increasing operating system diversity.
TDP’s project focused on several areas including but not limited to:
Providing relevant “simple English” documentation with translations for Tor operators on BSD systems;
-Relay guides in English, Spanish, Arabic, Portuguese, Russian and Polish;
-Documentation for building “small systems” on both FreeBSD and OpenBSD
-Documentation for Corporate Relays
-OpenBSD chroot how-to
-Conducting various promotion activities focused on the BSD community, including enlisting BSD-using commercial entities to run BSD relays with TDP providing assistance;
-Updating the equipment on active OpenBSD relays;
-Porting Onionshare to OpenBSD;
-Porting obfs4proxy to OpenBSD and FreeBSD;
-Migrating previous static reporting on the Tor network to JSON to highlight operating system-related diversity.
