Some companies have begun sharing information about how Bitcoins are being spent , a move that could mean that any of the digital currency that is used to buy child sex and images could be tracked and blocked . The Internet Watch Foundation ( IWF ) , which tracks abuse sites , has teamed up with Elliptic , which helps Bitcoin exchanges to monitor transactions . The fact that Bitcoins provide the buyer with some degree of security has reportedly made them an increasingly popular form of payment on abuse sites . The IWF ’s work has given it a list of Bitcoin addresses associated with sites selling abusive content . "We are seeing it being used on the more dedicated commercial abuse sites that we monitor on a regular basis," said Sarah Smith, IWF's technical researcher. Elliptic is now using this list in its attempts to curb the illicit use of the digital currency .
