Getting up to speed on Tor's past, present, and future

  1. First, read the overview page to get a basic idea of how Tor works, what it's for, and who uses it.
  2. Install the Tor bundle and try it out. Make sure you've got Firefox installed first, and be sure to read the list of warnings about ways you can screw up your anonymity.
  3. Download and watch Roger's overview talk from What The Hack (video, slides, abstract). This talk was given in July 2005, back when we were funded by EFF and back when the network was quite small, but it still provides good background on how Tor works and what it's for.
  4. Our FAQ covers all sorts of topics, including questions about setting up a client or relay, concerns about anonymity attacks, why we didn't build Tor in other ways, and discussion of Tor users and abuse.
  5. Tor has a blog now. We try to keep it updated every week or two with the latest news.
  6. Look through our Design Documents. Notice that we have RFC-style specs to tell you exactly how Tor is built.
  7. There's a skeletal list of items we'd like to tackle in the future. Alas, many of those items need to be fleshed out more before they'll make sense to people who aren't Tor developers, but you can still get a general sense of what issues need to be resolved next.
  8. Download and watch Nick's "Technical changes since 2004" talk from Defcon in July 2007 (video, slides), Roger's "blocking-resistance and circumvention" talk from 23C3 in December 2006 (video, slides, abstract, design paper), and Roger's "Current events in 2007" talk from 24C3 in December 2007 (video, slides, abstract). We also have the What The Hack tutorial on hidden services (video, slides).
  9. See Mike's "Securing the Tor network" talk from Defcon in July 2007 (video, slides). It describes common ways to attack networks like Tor, how we try to defend against them and introduces the Torflow script collection.
  10. Learn about the Tor proposal process for changing our design, and look over the existing proposals.
  11. Our developer TODO file starts with a timeline for external promises — things our sponsors have paid to see done. It also lists many other tasks and topics we'd like to tackle next.
  12. Once you're up to speed, things will continue to change surprisingly fast. The or-dev mailing list is where the complex discussion happens, and the #tor IRC channel is where the less complex discussion happens.
