In fact Bitcoin design does not contain elements hinting that anonymity was ever a goal. People using Bitcoin over Tor might just want to circumvent censorship aka Tor as glorified proxy.
- s_q_b 12y agoRight, but it doesn't work. That's the whole point of the article. Tor+random app usually equals massive vulnerability. I should add I learned that the hard way trying to integrate Tor with OpenBazaar. What might be fun is stenography over the Tor protocol. Anybody interested?
- selimthegrim 12y agoThere is a project that uses stenography to hide the Tor protocol from inspection. I need to tie up a few loose ends to some of my branches for it (I am not the originator, just a contributor) but have gotten caught up in schoolwork these last few months. Any assistance is appreciated!

- s_q_b 12y agoCool, I'll check it out. I was thinking more along the lines of hiding messages in the Tor protocol itself, rather than hiding Tor traffic (which is desperately needed.)
- VMG 12y agoIf I understand the paper correctly, you can't rely on Tor for that either. You can disable other Bitcoin peers on the Tor network: > It turns out that by exploiting a Bitcoin built-in reputation based DoS protection an attacker is able to force specific Bitcoin peers to ban Tor Exit nodes of her choice. Section VII lists some countermeasures. Very happy to see academics having an increasing interest in this area.
