DOJ retrial request puts roman storm trial back in spotlight over Tornado Cash and crypto mixers

As U.S. authorities clash over how to regulate crypto mixers, the roman storm trial is emerging as a key test for open-source developers and financial privacy tools.

DOJ seeks new Manhattan jury for Tornado Cash developer

The U.S. Justice Department has asked a Manhattan federal court to schedule a new trial in October 2026 for Roman Storm, a lead developer of the Tornado Cash protocol. Prosecutors want to retry him on unresolved conspiracy counts tied to alleged money laundering and sanctions violations.

According to the filing, federal prosecutors requested that Judge Katherine Polk Failla set jury selection for either October 5 or October 12, 2026. They told the court that Storm’s defense team had indicated it would be available during that period and argued that fixing dates now would avoid further delays.

However, the defense pushed back against scheduling a new proceeding before the court resolves Storm’s pending Rule 29 motion. That motion, which seeks an acquittal on legal grounds, is set for oral argument on April 9. The outcome could shape what remains of the criminal case.

Background of the split verdict in the first trial

The retrial request follows Storm’s first jury trial in Manhattan last August. In that earlier case, jurors convicted him of conspiring to operate an unlicensed money-transmitting business, but they failed to reach a verdict on two other conspiracy counts, leaving those charges unresolved.

Moreover, prosecutors said they intend to retry Storm on counts one and three, which focus on alleged money-laundering conspiracy and sanctions-evasion conspiracy. The Justice Department estimated that any new trial would last about three weeks, underscoring the complexity of the evidence and testimony.

After the retrial filing became public, Storm responded on X. He wrote that he would “never stop fighting for freedom” and claimed the government was targeting him “for writing open-source code.” However, he also said he had exhausted his legal defense funds, highlighting the financial strain of prolonged litigation.

Policy tension over mixers and financial privacy

The renewed push for a retrial arrived as U.S. policy on crypto mixer privacy tools appeared increasingly divided. On Monday, the Treasury Department sent Congress a report on digital asset crime controls, acknowledging that lawful users may employ mixers to protect financial privacy on public blockchains.

At the same time, regulators continued to warn that those same technologies can facilitate illicit finance. The department’s report stressed that mixers can be misused for sanctions violations, fraud, and other crimes, even as it recognized legitimate privacy needs. That tension has become central to how courts and agencies assess non-custodial software.

The roman storm trial has become a proxy battle in that debate, with policymakers and industry groups watching for signals on how far prosecutors can go when charging developers whose code can be used by anyone.

Tornado Cash sanctions saga and its reversal

Tornado Cash itself had been sanctioned by Treasury in August 2022. U.S. officials alleged that more than $7 billion had moved through the protocol since 2019, including funds linked to North Korea’s Lazarus Group, according to government statements at the time.

However, a court later ruled that the initial sanctions were unlawful. After an appellate panel questioned the agency’s authority over open-source smart contracts, Treasury ultimately lifted the restrictions. That reversal added new scrutiny to Storm’s prosecution and raised fresh questions about the legal status of decentralized protocols.

Cybercrime consultant David Sehyeon Baek told Decrypt that the government’s approach now appears inconsistent. He argued that Treasury is publicly acknowledging lawful uses for mixers even as the DOJ advances an aggressive theory of criminal liability for a Tornado Cash developer.

Developer liability case and legislative push

Supporters of Storm insist that the dispute is fundamentally a developer liability case. They say open-source coders should not be held criminally responsible for what others choose to do with publicly available software, particularly when those developers do not control user funds.

Moreover, Miller Whitehouse-Levine of the Solana Policy Institute described the decision to seek a retrial as “depressing” in a post on X. His organization has pledged support for Storm’s legal defense, framing the matter as a broader fight over innovation and civil liberties in the digital asset sector.

That said, the clash has also migrated to Capitol Hill. The Blockchain Regulatory Certainty Act, reintroduced in January by Senators Cynthia Lummis and Ron Wyden, would ensure that non-custodial developers are not treated as money transmitters when they lack the ability to move customer funds directly.

Next steps for the roman storm trial and crypto policy

For now, the immediate focus remains on Storm’s pending Rule 29 acquittal motion, which the court will hear on April 9 before addressing any new trial dates. The judge’s ruling could narrow the case or leave the unresolved counts in place.

However, regardless of scheduling, legal observers expect the Tornado Cash proceedings to remain a central reference point for future enforcement actions and the evolving treasury crypto report framework. The outcome is likely to influence how U.S. authorities balance code, privacy, and liability in the years ahead.

In summary, the case against Roman Storm now sits at the crossroads of criminal law, sanctions policy, and open-source software rights, making its next phase a pivotal moment for the broader crypto ecosystem.
