"Why would I want to set this field?" Because you're a good relay operator and therefor you don't "know" your relays are "clean" with certainty [sufficiently advanced stupidity is indistinguishable from malice...] Even if you were arrogant enough to believe that they were "clean" [absence of evidence in not evidence of ...

I'm no expert, but here's what I know: Guards/Relays If an adversary sets up multiple relay servers around the world, all they would get is a bunch of encrypted traffic. In fact, they'd actually be helping. According to the Lifecycle of a Relay, it could take up to 68 days for a new Guard relay to see any meaningful traffic. Even so, the adversary would ...

Think about this instead from the perspective of the Tor Project. Say you're a dev and you notice that a bunch of nodes that appear to be operated by the same person, but they aren't grouped together in a family. It's possible this is an accident, but it should also throw up a red flag for you because it may be an intentional ploy to deanonymize users - so ...

There are multiple practical reasons where five ORs of bandwidth X MB/s each could be superior to one OR of bandwidth 5X MB/s. There are some restrictions and exceptions to this point in general. This list is not meant to be the comperhensive list of all possible advantages and/or disadvantages, but give you enough clues to get the idea. Let us start and ...

From: Top changes in Tor since the 2004 design paper (Part 2) Bandwidth Authorities Of course, once you choose nodes with unequal probability, you open the possibility of an attacker trying to see a disproportionate number of circuits -- not by running an extra-high number of nodes -- but by claiming to have a very large bandwidth. For a while, we tried to ...

Only the Guard node would ever see your IP. The exit node would not see it and the middle node would not see it and the Guard node does not cache it in any way. Furthermore your connection changes every 10 minutes and most of the time each hop is in another country. The police would have to break Tor encryption multiple times through multiple servers in ...

As already commented, there are only three relays a normal circuit goes through. The exit relay obviously knows it is the exit - because it is asked to make a connection to the outside world. For middle and entry nodes, it is not as clear-cut, but still pretty easy to figure out in most cases: If the connection comes from a known Tor relay IP address, most ...

I think it is important to continue to spread the word. I can see my peers opening up to Tor after they understand it is not 'just for criminals' but serves a greater purpose for everyone. My way of helping is to run my own relay, even though my bandwidth is not very high, and to use it as my own entry point. I believe this helps my browsing be more secure.
