Empire Market is easily the largest darknet market operating right now. Founded on January 31st, 2019, just after the loss of Alphabay, Empire has attempted to go above and beyond in providing just as high of a quality of service as Alphabay did.
The design of Empire is an homage to Alphabay, and it's plain to see the lengths the administration has gone to in creating a high quality, expansive market. Among other things, Empire provides mandatory PGP 2FA for vendors, a powerful autoshop for accounts and other fraud-related items like credit cards, support for multiple cryptocurrencies, and forums in which vendors can advertise their items, or users can ask for and offer support in market-related matters.
As of writing, Empire has over 45000 active listings. No matter what you're looking for, you are almost certain to find it on the Empire Market
