A U.S. court nullifies Tornado Cash sanctions, ruling its smart contracts aren't property, sparking debates on blockchain regulation.

A U.S. federal appeals court has overturned sanctions placed on Tornado Cash, a widely used crypto-mixing service, ruling that its smart contracts cannot be considered property. The decision, made by the Fifth Circuit Court of Appeals, is seen as a major win for advocates of decentralization and privacy. At the same time, it has reignited debates about how blockchain tools, often tied to illegal activities, should be regulated.

The Treasury Department's Office of Foreign Assets Control (OFAC) had sanctioned Tornado Cash in 2022, alleging it was used by groups like North Korea's Lazarus Group to launder stolen funds. However, the court found that OFAC had overreached its authority. Tornado Cash operates through immutable smart contracts on the Ethereum blockchain, which function autonomously without human control. The court determined these contracts do not qualify as property under the International Emergency Economic Powers Act (IEEPA) because they cannot be owned or restricted.

The judges emphasized that while sanctions can block specific users from interacting with Tornado Cash, its decentralized nature means no one, including hackers, can be completely barred from accessing the service. Coinbase Chief Legal Officer Paul Grewal celebrated the ruling, calling it a "historic win" for crypto and individual freedoms. He stated, "Sanctioning open-source technology because a small portion of users misuse it is an overreach of government authority." Coinbase, along with other entities, had sued the government over the sanctions, arguing they unfairly targeted decentralized tools rather than addressing misuse directly.

Following the court’s decision, Tornado Cash's native token, TORN, surged nearly 400%, signaling optimism among decentralized finance (DeFi) supporters. This spike highlights confidence in the resilience of privacy-focused blockchain technologies.


The ruling also raises broader questions about how decentralized systems fit into current legal frameworks. Tornado Cash and similar crypto-mixing services occupy a legal gray area. They don’t operate like traditional financial institutions and cannot be controlled by a single authority. Critics warn the decision might embolden criminals to exploit blockchain tools, creating challenges for regulators.

Supporters of the decision argue that technology itself should not be blamed for its misuse. The court’s emphasis on distinguishing tools from bad actors could set a precedent for how decentralized technologies are treated in the future. Still, lawmakers and regulators are likely to scrutinize these services further to balance innovation with security.

In summary, the court's decision has reaffirmed the decentralized nature of smart contracts while exposing gaps in how existing laws address emerging blockchain technologies. As debates over crypto regulation continue, the Tornado Cash ruling underscores the tension between promoting innovation and preventing criminal misuse.
