Tornado Cash Co-Founder Convicted: A Landmark Case for Crypto Privacy

Roman Storm, co-founder of the crypto privacy protocol Tornado Cash, has been found guilty of operating an unlicensed money-transmitting business. However, the jury did not reach a decision on the more serious allegations of money laundering and violating U.S. sanctions, especially those related to North Korea’s Lazarus Group.

While Storm now faces a potential prison sentence of up to five years, the unresolved charges leave the door open for a possible retrial. Regardless of what happens next in court, the verdict has already sent a strong signal across the crypto industry: privacy-focused protocols are now under legal scrutiny.

Tornado Cash, a tool designed to break the link between wallet addresses on Ethereum, has long been a point of contention. To many users, it represented the right to financial privacy. But to regulators, it became a platform that allowed billions of dollars in illicit crypto to move undetected.

Storm argued that he was merely a developer who wrote and published open-source code, which ran autonomously once deployed. Yet prosecutors claimed his involvement went further, suggesting that his actions amounted to operating a financial service without regulatory approval. The jury sided with that argument, at least partially.

The Future of Crypto Privacy Is on the Line

This case raises critical questions about accountability in decentralized systems. For years, developers of DeFi protocols have operated under the belief that decentralization shields them from liability. Storm’s conviction challenges that assumption.

From here, developers may need to think more carefully about how privacy tools are launched and promoted. Publishing code alone might not trigger enforcement, but marketing, funding, and support structures could be viewed as signs of active participation.

The ruling also highlights an evolving regulatory approach. While Tornado Cash had no CEO, no office, and no traditional infrastructure, authorities still pursued its creators by focusing on outcomes rather than technical structure. That shift suggests regulators are becoming more adept at navigating the nuances of blockchain-based systems.

With the jury unable to reach a conclusion on the laundering and sanctions charges, further legal action remains possible. But even without additional convictions, the industry is already rethinking how to balance privacy and compliance.

Will we see fewer privacy mixers and more built-in regulatory controls? Can zero-knowledge systems offer both privacy and auditability? The answers are still unclear, but the pressure is mounting.

What’s certain is that the Tornado Cash case marks a turning point. Tools that once lived in the gray areas of crypto are now facing the full force of legal interpretation. In today’s environment, developers will be judged not only by the code they write, but by the impact that code has in the real world.
