Although it was certainly the most high profile, Silk Road was not the first illegal marketplace hidden within the dark web or on the open internet.
"Silk Road will almost certainly be replaced by a copycat-like site, as has been the case in carder markets where people trade fraudulent credit card information. Those kinds of places have been shut down in the past and very, very quickly replaced by others," said Rik Ferguson, vice-president of security research at Trend Micro, talking to the Guardian.
Sites similar to Silk Road already exist within the Tor network. Two stores called Atlantis and Sheep Marketplace offer illegal drugs, equipment and services akin to Silk Road.
However, some sites go further – Bitcoin-powered shop called Black Market Road, for instance, also sells illegal weapons, something Silk Road withdrew after high profile shootings in the US.
