Silk Road: Bitcoin's First Killer App Was Illegal

On the afternoon of 1 October 2013, a 29-year-old man sat at a laptop in the Glen Park branch of the San Francisco Public Library. Federal agents staged a distraction, grabbed the open laptop before he could close it and arrested him. Ross Ulbricht, a physics graduate from Austin, Texas, was charged with running Silk Road, the largest drug market on the internet, under the name "Dread Pirate Roberts".

In under three years, the site had become Bitcoin's first mass-market use. According to the FBI's criminal complaint, buyers and sellers on Silk Road traded 9,519,664 bitcoins' worth of goods between February 2011 and July 2013, about $1.2 billion at the exchange rate of the day. The site took commissions of 614,305 bitcoins, about $79.8 million. Prosecutors later said more than 100,000 buyers had used it.

A drug market that needed new money

Silk Road opened in January 2011. It ran on Tor, a free network that bounces traffic through volunteer computers around the world so that neither the website's location nor its visitors' locations can easily be traced. That solved one problem for a drug market. Payment was the other. Credit cards and bank transfers leave a name on every transaction.

Bitcoin filled that gap. It is digital money that moves directly between users without a bank in the middle, a little like handing over cash, except the cash travels over the internet. Every payment is recorded on a public ledger called the blockchain, but the ledger shows account numbers, not names. Silk Road held buyers' coins in its own accounts until the goods arrived, rather like a lawyer holding a deposit until a house sale completes, and then released them to the seller.

The site was almost unknown until 1 June 2011, when the website Gawker published an article by Adrian Chen describing the "underground website where you can buy any drug imaginable". Politicians demanded it be shut. Traffic rose. So did demand for bitcoin, which until then had been a hobby for programmers and cryptography enthusiasts. For a period in 2011 and 2012, Silk Road was the main thing bitcoin could actually be spent on.

By September 2013 the site carried nearly 13,000 listings for drugs, according to the government, along with forged documents, hacking services and stolen digital goods. Investigators made more than 60 undercover purchases from sellers believed to be in more than ten countries.

The case against Dread Pirate Roberts

The investigation traced Ulbricht through small mistakes, including early forum posts promoting the site and asking for programming help under an account linked to his personal email address. After his arrest, the FBI seized about 29,655 bitcoins from Silk Road's servers and 144,336 bitcoins from his computer, about 174,000 coins in all.

In February 2015, after a four-week trial in Manhattan, a jury convicted him on all seven counts, including distributing narcotics over the internet, running a continuing criminal enterprise, conspiring to commit computer hacking and conspiring to launder money. On 29 May 2015 Judge Katherine Forrest sentenced him to life in prison without parole and ordered him to forfeit $183,961,921. Prosecutors linked drugs bought on the site to at least six overdose deaths, and said Ulbricht had solicited six murders-for-hire to protect the business. The government said there was no evidence any of those killings took place. He was never tried on them: a separate Maryland murder-for-hire indictment was dismissed in July 2018, and Ulbricht has always denied the allegations.

The investigation had its own crimes. Two federal agents on the Baltimore task force, Carl Force of the Drug Enforcement Administration and Shaun Bridges of the Secret Service, stole bitcoin during the case. Force was sentenced to 78 months in October 2015 and Bridges to 71 months that December.

Ulbricht's appeals failed. The Second Circuit upheld the conviction and sentence on 31 May 2017, and the Supreme Court declined to hear the case on 28 June 2018. A campaign led by his mother, Lyn Ulbricht, kept his name in front of crypto conferences and libertarian groups for a decade.

Where the coins went

The US Marshals Service, which sells property seized by federal agencies, auctioned the Silk Road coins in batches. In June 2014 the venture capitalist Tim Draper bought the entire first lot of about 29,656 BTC. A second auction of 50,000 coins followed in December 2014, and the rest were sold in 2015. The government took in tens of millions of dollars. At about $82,000 a coin in October 2026, the 174,000 coins would be worth roughly $14 billion.

Silk Road coins kept turning up long after the site closed. In November 2020 the Justice Department seized 69,370 BTC that a hacker known only as "Individual X" had taken from Silk Road years earlier. In 2021 Ulbricht gave up any claim to those coins, and the government agreed that money from selling them would count against his $183.9 million forfeiture bill, CoinDesk reported. In November 2021 agents searching the Gainesville, Georgia, home of James Zhong found 50,676 BTC, some of it on a small computer hidden in a popcorn tin. Zhong had tricked Silk Road's withdrawal system in 2012. He pleaded guilty to wire fraud and in April 2023 was sentenced to a year and a day in prison.

Pardon, and a new career on stage

During the 2024 campaign Donald Trump promised to free Ulbricht. On 21 January 2025, his first full day back in office, he announced a "full and unconditional pardon" on Truth Social, calling the prosecutors "scum" and the sentence "ridiculous". Ulbricht had served more than 11 years. Critics said it played down the harm done by a market that prosecutors had linked to overdose deaths.

Ulbricht spoke at the Bitcoin 2025 conference in Las Vegas in May 2025. On 31 May 2025 his donation wallet received 300 BTC, about $31 million, from an unknown sender, a transfer first flagged by the analytics services Lookonchain and Arkham Intelligence. The blockchain investigator ZachXBT traced the coins through a mixing service, which pools coins to hide their origin, and concluded the gift was probably not from Ulbricht himself. The donor has never been identified.

In September 2026 Ulbricht addressed the Republican Party's midterm convention, thanking Trump for his freedom and warning against government power being turned on political opponents. Robert Reich, the former US labor secretary, criticised the appearance, describing Ulbricht as one of many "white-collar criminals" Trump had pardoned. Silk Road itself has been dead for 13 years. Its successors, from AlphaBay to Hydra, were shut down too. The money it ran on is now held by Wall Street funds and the US government.
