Andreas is summoned for Ulbrich's defense? I don't think it's a good idea. I am not certain Ulbrich is innocent or guilty, but Andreas working against the prosecution will put Andreas in an awkard position.
He was summoned by the defense, but he's simply being asked to explain Bitcoin. So far the prosecution have been talking about "the dark web" and drugs and murder-for-hire and trying to make Ulbricht look guilty because he has lots of this "evil" Bitcoin currency. I guess they are going to ask Andreas about Bitcoin in general, it's legitimate uses and how early adopters, such as Ross, have made lots of money due to it's rapid increase in value. He will probably also explain how the Silk Road tumbler and MtGox hot wallet were very closely connected, with many withdrawals from MtGox being SR tainted coins and many SR withdrawals being tainted with MtGox's hot wallet. Also he will likely explain how 13% of all Bitcoin addresses are tainted with Silk Road coins and why simply finding tainted coins on his machine probably isn't evidence as it's likely most Bitcoin users have some small amount of SR tainted coins even if they have never visited SR.
