Roman Storm Trial: Is Coding A Crime? The Tornado Cash Court Battle Intensifies

The trial of Tornado Cash developer Roman Storm concluded its prosecution phase, with the government presenting eight days of witness testimony. The prosecution argued that Storm, along with alleged co-conspirators, owned and controlled Tornado Cash, profiting from its use by criminals, including North Korean hackers, despite knowing this activity. They highlighted Storm’s alleged inaction when victims sought help, claiming this constitutes conspiracy to commit money laundering, sanctions evasion, and violation of international sanctions – crimes carrying a potential 45-year sentence.

The defense’s case began with Ethereum core developer Preston Van Loon, a Tornado Cash user who testified about its use for operational security and personal safety. The defense’s strategy centers on portraying Tornado Cash as a privacy tool with legitimate uses, comparable to encryption apps or VPNs, that was unfortunately exploited by malicious actors. They contend Storm’s actions, at worst, were negligent, not criminal.

A key point of contention involves the testimony of Hanfeng Lin, a victim of a scam who claimed that a portion of her lost funds was traced to Tornado Cash by Payback, a crypto tracing company. However, blockchain sleuth Taylor Monahan refuted this claim, stating the tracing was inaccurate, a finding corroborated by other experts. This led the defense to consider a mistrial, but the judge allowed IRS agent Stephan George to testify as an expert witness to validate the initial tracing.

George’s testimony, however, revealed weaknesses. He admitted his tracing method didn’t establish wallet ownership or prove Lin’s scammers used Tornado Cash, and he showed limited knowledge of relevant cryptocurrencies and exchanges. His use of the LIFO (last in, first out) accounting principle in tracing was also questioned.

The defense will now present its witnesses, including an expert and Columbia Business School professor Omid Malekan, aiming to counter the prosecution’s narrative and challenge the accusations against Storm. Their testimony will focus on the legitimate use of Tornado Cash and attempt to diminish the severity of Storm’s alleged involvement in criminal activity.
