Silk Road by numbers: What the FBI found when it seized drug-dealing web server

As the Silk Road trial neared the end of its tenth day, the prosecution ended its case against Ross Ulbricht, accused of running the drug-dealing site, with a breakdown of its finances.

Having located Silk Road's server, FBI and Department of Homeland Security agents were able to log every transaction ever made through the site, which resided on the dark web, an area of the internet hidden from search engines like Google.

FBI contractor Brian Shaw took the stand to present his analysis on how Silk Road worked and how much money it made. Here is what he told the court:

$182.9m (£122m) - The total value of drugs sold on the Silk Road website between its launch in early 2011 and its closure by the FBI in October 2013 - far less than the $1.2bn first estimated by law enforcement.

$213.8m - Total revenue, earned from 9,912,070 bitcoins

$13.17m - Total commission, earned from 642,455 bitcoins

4% - The percentage of sales on Silk Road, by value, which were not drug-related. These include sales of fake currency and counterfeit ID like passports and driving licenses.

$1m- The value of fake IDs and passports sold on Silk Road

$3m - The value of currency sold on Silk Road, such as gold and silver, and the work of some vendors who offered cash in exchange for bitcoins

1.53m - The number of transactions recorded in the site's history.

3,748 seller accounts sold drugs and other items to 115,391 buyer accounts

Ulbricht, 30, faces charges of narcotics trafficking, computer hacking, money laundering and conspiracy to traffic fraudulent IDs, with a maximum sentence of up to life in prison.

But the most serious charge is of engaging in "continuing criminal enterprise," a charge usually reserved for the leaders of organised gangs and mafia bosses; this adds at least 20 years to Ulbricht's minimum sentence (with the potential for life) and is sometimes referred to as "the kingpin status". In all, Ulbricht faces a minimum of 30 years in prison if found guilty on all charges.

Ulbricht has pleaded not-guilty, but his defence team said in their opening remarks two weeks ago that he created the website as an "economic experiment" in early 2011, but handed over the reins to an unknown person soon after, because it was causing him too much stress.

His lawyer, Joshua Dratel, claims Ulbricht was then lured back to run the site when its owners heard about the imminent FBI seizure, which took place in October 2013.

Ulbricht was arrested and his seized laptop, full of chat conversations alleged to be between him and Silk Road users, employed administrators and an undercover agent, has proved to be a key piece of evidence in the case against him.

The trial continues next week, where the defence will take the stand. Ulbricht has told the judge he will not be testifying, although he can change his mind if he wishes.
