A Landmark Victory for Crypto Privacy, Decentralization & Open-source Technology
In a pivotal decision, a U.S. Appeals Court has nullified the U.S. Treasury Department’s sanctions on Tornado Cash, marking a significant achievement for the cryptocurrency sector. The judgment has been applauded as a win for digital privacy, decentralized systems, and open-source innovation.
Appeals Court Strikes Down Treasury’s Action Against Tornado Cash
The U.S. Department of Treasury’s Office of Foreign Asset Control (OFAC) blacklisted Tornado Cash in August 2022, banning its use by U.S. residents and entities. This action triggered widespread criticism from privacy advocates and blockchain enthusiasts, who argued it overstepped legal boundaries.
On November 26, 2024, the Appeals Court overturned a prior ruling, asserting that the Treasury Department had exceeded its authority. The court emphasized that Tornado Cash’s immutable smart contracts—self-executing code on the blockchain—do not constitute property or services controlled by foreign entities, thereby falling outside the scope of the International Emergency Economic Powers Act (IEEPA).
Immutable Smart Contracts and Legal Boundaries
The court ruled that Tornado Cash’s open-source, unchangeable smart contracts cannot be classified as property since no individual or organization has ownership or control over them.
“While OFAC’s concerns about illicit financial activity are valid, Tornado Cash’s smart contracts do not meet the criteria for property under IEEPA. Consequently, the Treasury overstepped its legal limits,” the court stated.
The decision also acknowledged that Tornado Cash’s smart contracts continue operating despite the sanctions, potentially exposing U.S. users to unintentional legal risks if funds are transferred to their accounts without consent.
Industry Response: A Breakthrough for Privacy and Open-Source Technology
The ruling has sparked celebration among blockchain proponents. Paul Grewal, Chief Legal Officer at Coinbase, described the decision as a “historic milestone for digital privacy and decentralized technology.” Similarly, Consensys Senior Counsel Bill Hughes highlighted its importance in strengthening the legal standing of open-source projects.
The judgment represents a significant step forward in recognizing the autonomy of blockchain-based technologies. By affirming the immutability of smart contracts, it sets a precedent that could encourage further innovation in the sector.
Impact on Tornado Cash Developers
While the ruling safeguards the technology behind Tornado Cash, it does not directly address the legal challenges faced by its developers, including Alexey Pertsev, Roman Storm, and Roman Semenov. Pertsev, who was convicted in the Netherlands for money laundering, is appealing his 64-month sentence. Meanwhile, Storm and Semenov face similar charges in the U.S., with Semenov’s whereabouts currently unknown.
Bill Hughes clarified that the case focuses on the smart contracts themselves rather than the broader platform operations. Authorities allege the platform facilitated illegal transactions, which is distinct from the legality of its underlying code.
“This decision does not absolve developers from accusations of operating a service that violated sanctions or enabled illicit activities,” Hughes remarked.
Broader Implications of the Decision
Although the case has been sent back to the district court for further deliberation, the Appeals Court’s ruling establishes a vital legal benchmark for decentralized platforms. It underscores the importance of balancing regulatory oversight with the protection of privacy and technological advancement, a challenge that will shape the evolution of blockchain technology.
