Since the creation of the Silk Road, authorities have waged a war against the online drug trade with a wave of surveillance and enforcement. However, crypto-anarchists are developing new ways to evade the state's tentacles as the next technological phase started to emerge in late 2017. On Monday, the Cypherpunk Bitstream podcast discussed the evolution of darknet markets as new ideas like Dropgangs and Dead Drops proliferate into the next decade.
The Evolution of Darknet Markets
According to a Vice report from the end of 2019, the number of users buying illicit drugs on darknet markets (DNMs) has doubled since 2014. While the Silk Road was shut down, new markets like Dream and Alphabay quickly emerged. However, in 2017, police shut down Alphabay and covertly operated Hansa for over 30 days, severely disrupting client-merchant relationships. Jonathan 'Smuggler' Logan, the author of the article "Dropgangs, or the Future of Darknet Markets," argues that centralized DNMs have fundamental flaws: once servers are seized, all reputation and customer connections vanish.
What Are Dropgangs?
Dropgangs are organizations that distribute contraband using messaging services like Telegram, cryptocurrencies, and physical dead drops. Buyers negotiate via messaging apps, agree on a price, and receive GPS coordinates of a secret location where the goods are stashed. This model bypasses the global postal system entirely, significantly reducing the risk of detection. Smuggler emphasized on the podcast that "darknet markets are not the end of development when it comes to the distribution of contraband." In Eastern Europe and the Balkans, dead drops have become dominant because the postal system in those regions has never been trustworthy. The dead drop method allows vendors to hide products at random geographical locations known only to the two parties, keeping customers anonymous without revealing their addresses.
Postal Service Vulnerabilities and Countermeasures
The podcast detailed how postal services use digital tracking to flag suspicious packages. For example, letters are printed with invisible tracing codes, which then mark all mail posted in the same container, generating heat maps that help investigators locate sellers and determine shipping frequency. Smuggler explained that this kind of mail inspection gives investigators a very good indication of the sender's origin and shipping frequency. Dropgangs completely avoid this vulnerability by eliminating the need for postal delivery altogether.
Drone Mix Networks and Sneakernet
Beyond Dropgangs, the podcast discussed Drone Mix Networks, which would combine drones for physical delivery with hard-to-trace communication mixes. Another concept is sneakernet — transferring data via physical devices like USB drives, optical discs, or external hard drives. For instance, a person could create a Bitcoin Cash (BCH) bearer bond on an optical disc and pass it along a network of individuals without any transaction ever being seen on a public block explorer. Such methods may become essential after the Fifth Anti-Money Laundering Directive (5AMLD) and the FATF Travel Rule take effect.
Early Decentralized Marketplace Attempts
In August 2015, Reddit user miracle-max_ described the Drop Zone Protocol, a decentralized marketplace layer on top of the Bitcoin chain. Another project, Bitmarkets, used Bitmessage for listings and communications and ran on Tor by default. Neither gained widespread adoption, and people remained dependent on centralized DNMs until 2017. After the major DNM takedowns, the peer-to-peer platform OpenBazaar was lightly used for contraband, mainly cannabis. Looking ahead, Dropgangs and similar models are likely to evolve as the cat-and-mouse game between law enforcement and privacy advocates continues.
