Police from the national economic crimes unit on Tuesday arrested 30 suspects they say ran an online drug distribution network, cooking and selling drugs through using the “Darknet”, according to police."Darknet" is a general term used to describe file-sharing and other sites on the internet where a user'sIP address is not used making it very difficult for users to be traced. Such sites have been used to share child pornography, for the drug trade, and by dissident movements that don't want their online usage to be tracked by governments.Police said that over the past few months they've run an undercover investigation against the network, making purchases of drugs online. Police said the drugs bought online were part of a network that shipped the drugs to a kiosk in Tel Aviv, from where they were distributed around the city and beyond.Police said that they believe the system may have been using "bitcoins", the peer-to-peer digital currency. Bitcoins aren't controlled or regulated by any country or company, and the difficulty in tracing their use has made them popular for online drug purchases and other illicit activities.On Tuesday police raided the homes of suspects who they say included those who ran the website and were in charge of the sales and supply side of the drug network.
