This week Dark Net plunges into the fascinating and sometimes murky world of digital money as virtual currencies like bitcoin start to have real economic significance.
Bitcoin might have started with a 10,000 bitcoin pizza delivery but it now best known for its rags to riches reputation with tales of early adopter geeks making millions from the coins they mined relatively easily in the early days of the project.
The currency and others like it have been hailed as a revolution in how goods and services are paid for with the intermediaries like bank cut out of the transaction.
However, like most money there is also a much darker side to how it is used. The avoidance of the regular banking system means it is popular with criminals and online marketplaces selling everything from illegal drugs to weapons often use bitcoin as their means of transacting.
Conversely there are signs that some governments are now taking it seriously with Japan making it a legal payment method just this month.
Dark Net airs Thursdays at 10:00 PM on Showtime.
