During cross examination the jury was awake and interested in everything being said. Just from my observation the defense's strategy seems to be working. You have an agent testifying about how he was able to assume multiple different identities online and take over the moderator account "cirrus" without being detected so how can they then argue that there was only one DPR and Ulbricht was it? Keep in mind that Karpeles wasn't just a suspect, the agent believed he had probable cause to search Mr. Karpeles' email accounts.
if they were more interested in cross examination then the cross examination is likely going to have a greater impact on them. A very good point was made that the agent was able to assume multiple online identities - this should raise doubt in the prosecution's case.
The defense also poked many holes in the prosecution's case. The agent did not know exactly when the buyers and sellers guides were posted. The agent did not know when the escrow and commission system was started. The agent did not know when the bitcoin tumbler was started. The agent did not know when hacking equipment and software was first sold on Silk Road. These questions seem to imply that the defense is going to, as they already have, readily admit that Ulbricht had a hand in starting Silk Road but it is these features that add the damaging money laundering, conspiracy, and hacking charges.
This is a somewhat of a step in the right direction however the government is going to have more witnesses and can present evidence to show when this all happened (although they might not have access to the forum servers as it was not taken down when Silk Road was taken down).
The Bitcoin Talk forums were also brought up on Thursday. The defense is going to say that Karpeles created the Bitcoin Talk forums. And both the Bitcoin Talk forums and the Silk Road forums not only use the same software but the exact same version of the software even though other versions have come out. The defense will also make the point that this software is not commonly used to make online forums.
Karpeles didn't create bitcointalk? It was started by satoshi and sirus.
