AlphaBay is the largest darknet market in the world. It was shut down by police in July, but administrator DeSnake has relaunched it over the weekend. He announced plans to set up a platform for darknet markets with a strong focus on anonymity. DeSnake also laid out a set of rules for the new AlphaBay network. It is estimated that the market transacted at least $1 billion of cryptocurrency (mostly Bitcoin) since its creation. It currently has only two featured listings, both for drugs.
