Hey all,

I'm writing a book about the use of Bitcoin and anonymity. A fair portion of the book will be dedicated to teaching people how to most safely use Tor to facilitate anonymity with Bitcoin. Are there any special tips that people have for configuring Tor or using Tor when it comes to Bitcoin?

I'll have tutorials online "soon" (not in my hands) that cover this in great detail. I recommend mixing through at least three different mixing services, using independent anonymous wallets.

Right now, I'm recommending the use of a LiveCD Linux distro (Ubuntu) with TorBundle for Linux and the vanilla Bitcoin client for Linux. A couple tips I'm already aware of are to disable JavaScript before using (since NoScript currently defaults to being on :() and to avoid downloading files through the web browser such as PDF documents.

I recommend using Whonix with the Multibit client. The vanilla Bitcoin client downloads the full blockchain, which is far too much for Tor. It's comparable to torrenting an 8 GB video. Multibit is a local client, under user control, but doesn't download the blockchain. It's the recommended default now.

In particular, I'm curious 1) if there needs to be special configuration to ensure that all DNS request go through Tor, and 2) whether I can configure the system not to send any internet message except through the Tor proxy.

As I understand Whonix, it's designed not to leak. But I defer to adrelanos for specifics.
