Anti-censorship team report: August 2020

Tor’s anti-censorship team writes monthly reports to keep the world updated on its progress. This blog post summarizes the anti-censorship work we got done in August 2020. Let us know if you have any questions or feedback!




  • Decided to call our BridgeDB redesign rdsys, which is short for “resource distribution system.” Do you have a better name? If so, let us know!

  • Created a GitLab repository for rdsys. The code is a messy construction site and will continue to be in the foreseeable future.

  • Improved the way rdsys talks to bridgestrap to verify that bridges are working.

  • Built an HTTP streaming interface between rdsys’s backend and its distributors. This interface allows the backend to stream resource updates to the distributors without delay. The goal is that resources (i.e. bridges) are distributed to users immediately after they are added to the system.



  • Improved the service’s shutdown procedure, caching mechanism, its documentation, and its HTTP API. Added a command line flag to print bridgestrap’s cache.

  • Added a token bucket mechanism to limit the number of requests that the service accepts.
