consider tor stream isolation as a countermeasure #85

Open kristovatlas opened 8 years ago

core 0.11.0 introduced a feature (i think disabled by default) to use a different Tor circuit for each p2p connection. investigate for attacks/countermeasures

I think this is a new kind of attack in the Network observer category: Link a user's transaction data -- query or broadcast -- to their non-Bitcoin network activity. Stream isolation tackles this in a Tor context.

Since this is a subtle issue to capture correctly and because the attacks are feature-frozen for the 3rd edition milestone, I am incrementing the milestone.
