Roman Sterlingov was born around 1989 and holds dual Swedish and Russian citizenship. He was an early Bitcoin adopter and investor. Before his arrest, he had never been to the United States.
Bitcoin Fog was a cryptocurrency mixing service that operated on the darknet from October 2011 to April 2021. The service processed over 1.2 million Bitcoin transactions totaling approximately $400 million at the time. Prosecutors alleged the majority came from darknet marketplaces linked to drug trafficking, identity theft, and other criminal activity.
Roman was arrested April 27, 2021, at LAX. He was charged with money laundering, operating an unlicensed money transmitting business, and money transmission without a license. He was held in federal custody and denied access to seized funds for legal defense despite the court acknowledging his need.
Roman’s defense, led by Tor Ekeland, maintained throughout that Roman was a user of Bitcoin Fog, not its operator. The prosecution relied almost entirely on Chainalysis’s proprietary Reactor software. The defense challenged this methodology: it had never been peer-reviewed, the specific IP analysis was invented for this case, and CipherTrace’s independent analysis found no evidence linking Roman to Bitcoin Fog.
After a month-long trial in March 2024, the jury convicted on all four counts. On November 8, 2024, Judge Randolph Moss sentenced Roman to 150 months and ordered forfeiture of over $395 million.
In September 2025, ChainArgos filed an amicus brief demonstrating that Chainalysis’s trial evidence involved addresses outside its own Bitcoin Fog clusters — the prosecution’s tracing evidence contradicted its own analysis. Chainalysis filed its own amicus in support of the government in February 2026.
Roman’s case is the first criminal prosecution in the U.S. to go to jury trial based primarily on blockchain tracing evidence. If his conviction stands, it establishes a precedent that anyone can be convicted based on unverified proprietary software. If overturned, it will be the most important ruling on blockchain forensics reliability in the history of cryptocurrency law. His appeal hearing is May 12, 2026.
