Taking down Silk Road, the Bitcoin black market for goods and drugs sold around the world, didn’t just put a dent in the economy of crime. It has led authorities to be able to find and arrest the culprits who used it.

NOD, a well-known drug dealer on the defunct online black market Silk Road, has been arrested in Washington State, along with a partner. Across the Atlantic, four Silk Road users were arrested by British authorities “on suspicion of supplying controlled drugs.” In Sweden, two Silk Road users have been arrested for allegedly selling marijuana on the site.
