In a Manhattan courtroom, a quiet battle is unfolding. It pits the idea of digital privacy against the harsh reality of criminal misuse. At the center is Roman Storm, a software developer, and the crypto privacy tool he helped create, Tornado Cash.
- The trial centers on whether Roman Storm, the creator of Tornado Cash, is criminally responsible for its misuse by criminals. The prosecution and defense both agree that the tool was used for illicit activities.
- The core question is whether Storm knew about the criminal use and could have stopped it. He faces charges including money laundering and violating sanctions.
- The defense argues that Storm’s tool was misused by a minority of users, and that the primary purpose was to protect user privacy. They compare it to other tools that can be misused.
Both sides, the prosecution and the defense, agree on one stark fact. Tornado Cash, once a popular tool, was indeed used by hackers and cyber criminals. They used it to wash their illicit gains, making dirty money hard to trace.
The core question, the one the jury will grapple with, is whether Storm should be held criminally responsible. Did he know which criminals were using the protocol? Could he have stopped them? And does creating a tool, even one with a legitimate purpose, make you liable for its misuse?

Storm, 36, faces serious charges. These include conspiracy to commit money laundering, conspiracy to violate U.S. sanctions, and conspiracy to operate an unlicensed money transmitting business. If convicted, he could spend up to 45 years in prison. The trial began Monday in Manhattan, with opening arguments on Tuesday.
The Government’s Case
Prosecutor Kevin Mosley laid out the government’s argument. He told the jury that Roman Storm “knew that his business was laundering dirty money.” Mosley stated that Storm made millions from this activity.
The prosecution plans to show a photo of Storm wearing a t-shirt. This shirt depicts a washing machine with the Tornado Cash logo. Mosley suggested this image proves Storm’s awareness of how his product was being used.
Mosley claimed Storm ignored hackers using his platform. He also said Storm turned a blind eye to scam victims. These victims, Mosley stated, reached out for help recovering their funds. Storm either told them he couldn’t help or simply ignored them.
The prosecution asserts Storm kept full control over the Tornado Cash platform. They claim he even adjusted it “to make it even better for criminals to hide their money.” This suggests active facilitation, not just passive creation.
One notorious user of Tornado Cash was the Lazarus Group. This is North Korea’s state-sponsored hacking organization. They used Tornado Cash to launder funds from their 2022 hack of Axie Infinity’s Ronin Network. Mosley argued that by helping the Lazarus Group, Storm and his alleged “co-conspirators,” Alexey Pertsev and Roman Semenov, broke U.S. sanctions against North Korea.
Mosley pointed to a text message as further evidence. After news of the Axie Infinity hack broke, Storm allegedly texted Semenov and Pertsev, “guys, we’re done for.” The prosecution sees this as proof Storm knew he was helping North Korea bypass sanctions.
The Defense’s Stance
Storm’s lawyers, naturally, see things differently. Keri Axel, a partner at Waymaker LLP, presented the defense’s opening statements. She argued Storm’s text after the Axie Infinity hack had nothing to do with sanctions. Instead, she said, it concerned Tornado Cash’s reputation and the price of the TORN token, which dropped after the hack.
As for the washing machine t-shirt, Axel dismissed it as a joke. She called it a joke “in poor taste,” but nothing more. This tries to defuse a piece of evidence the prosecution clearly finds compelling.
Axel insisted Storm did not work with hackers or scammers. She stated he did not want them using his product. “These criminals, acting without any assistance from Roman (Storm), misused Tornado Cash,” Axel told the jury. She promised no evidence would show Storm communicated with or helped these bad actors.
The defense paints a picture of a creator whose dream was ruined. The fact that criminals constantly exploited Tornado Cash “ultimately killed his dream.” That dream was to build a privacy tool widely used and respected in the crypto world.
At the heart of Storm’s defense is the concept of privacy itself. His lawyers highlighted the legitimate need for it. Storm, a Kazakhstan-born U.S. citizen, taught himself to code. He worked odd jobs, like bus boy and security guard, before entering tech. He was inspired to create a privacy tool after meeting Ethereum co-founder Vitalik Buterin, whom Axel called a “crypto rockstar.”
Axel admitted Tornado Cash was “misused.” But she stressed that criminals were a minority of its users. Most users, she argued, were ordinary people. They used Tornado Cash simply to protect their privacy.
“It’s not a crime to make a useful thing that’s misused by bad people,” Axel stated. She drew analogies, comparing Tornado Cash to a smartphone used for scams. Or, she said, think of a hammer used to break into homes. The tool itself is not criminal, even if it can be used for crime.
She explained to the jury how the blockchain works. It is public and easily searchable. Any known wallet address can be found. Its transactions and contents can be viewed by anyone. This lack of privacy, Axel explained, has led to real-world dangers. She cited recent kidnappings and attacks on wealthy individuals and executives in the crypto industry.
“How would you feel if someone took your bank account and published it on the internet?” Axel asked the jury. “You would feel exposed and probably unsafe.” This question aims to make the abstract concept of blockchain privacy relatable.
Axel also addressed the upcoming testimony from victims and hackers. She told the jury that none of these witnesses could be directly linked to Roman Storm. The hackers, she suggested, are testifying “in the hopes that they can get leniency in their own criminal cases.” She maintained Storm lacked the power to help their victims.
The Trial Begins
After the opening statements, the government called its first witness. She is Hanfeng Ling, a Taiwan-born Georgia resident. Ms. Ling described how she fell victim to a “pig butchering” scam in the fall of 2021. This scam began with a wrong-number WhatsApp message.
The scammer convinced Ms. Ling to transfer nearly $200,000 from her savings. She used this money to buy crypto. Then, she was told to “invest” it in a fake foreign exchange trading platform. It’s a common, heartbreaking story in the crypto space, where anonymity can be a double-edged sword.
Ms. Ling’s testimony will continue. Nathan Rehn, the lead prosecutor, expects four more government witnesses to follow her. The trial is set to last three weeks, followed by jury deliberation. The outcome will surely send ripples through the crypto community, affecting how privacy tools are viewed and regulated.
