Tornado Cash, a cryptocurrency mixing service that aims to protect the privacy of its users, is facing a legal challenge from the U.S. government. Two of its co-founders, Roman Storm and Roman Semenov, have been charged with money laundering and sanctions violations, while a third developer, Alexey Pertsev, is in jail in The Netherlands. The case has drawn the attention and support of Edward Snowden, the former CIA contractor and whistleblower, who has urged the crypto community to donate to their legal defense fund.
What is Tornado Cash and why is it controversial?
Tornado Cash is a decentralized application (dApp) that runs on the Ethereum blockchain. It allows users to send and receive cryptocurrency anonymously, by obscuring the link between their wallet addresses. Users can deposit their funds into a smart contract, and withdraw them later to a different address, without revealing their identity or transaction history. Tornado Cash uses zero-knowledge proofs, a cryptographic technique that verifies a statement without revealing any information about it.
Tornado Cash claims to offer a legitimate service for users who value their financial privacy, such as activists, journalists, whistleblowers, or anyone who wants to avoid censorship, surveillance, or discrimination. However, the U.S. government alleges that Tornado Cash also facilitates money laundering, tax evasion, and sanctions evasion, by enabling criminals, terrorists, and rogue states to hide their illicit activities and funds. According to the indictment, more than $1 billion worth of cryptocurrency was moved through Tornado Cash between 2019 and 2023.
How did the U.S. authorities catch the Tornado Cash co-founders?
The U.S. Department of Justice (DOJ) and the Treasury Department’s Office of Foreign Assets Control (OFAC) have been investigating Tornado Cash since 2022, when they imposed sanctions on the dApp for allegedly being used by North Korean hackers to launder stolen funds. The sanctions prohibited anyone in the U.S. from engaging with Tornado Cash, including sending or receiving funds through it.
The DOJ and OFAC claim that they were able to identify and track some of the Tornado Cash users and transactions, by using blockchain analysis tools and cooperating with other law enforcement agencies and cryptocurrency exchanges. They also allege that they were able to link the Tornado Cash co-founders to the dApp, by tracing their online activities, social media accounts, and domain registrations.
Roman Storm, a dual U.S. and Russian citizen, was arrested in August 2023 in Washington State, where he resided. He was released on bail shortly after, on a $2 million bond secured against his residence. He has pleaded not guilty to the charges, and is awaiting trial in 2024. Roman Semenov, another co-founder and Russian citizen, was also charged, but has not been arrested. He is believed to be in Russia, which does not have an extradition treaty with the U.S. Alexey Pertsev, a developer and Ukrainian citizen, has been in jail since 2023 in The Netherlands, where he was arrested on a U.S. warrant. He is fighting extradition to the U.S.
How has the crypto community reacted to the case?
The case of Tornado Cash has sparked a debate in the crypto community, about the role and limits of privacy in the blockchain space. Some argue that Tornado Cash provides a valuable service for users who seek to protect their financial sovereignty and human rights, and that the U.S. government is overstepping its jurisdiction and authority, by trying to regulate and control a decentralized and global technology. Others contend that Tornado Cash enables and encourages illegal and unethical behavior, and that the U.S. government is justified in enforcing its laws and sanctions, to prevent and combat crime and terrorism.
The case has also attracted the support and sympathy of some prominent figures in the crypto and privacy spheres, such as Edward Snowden, the former CIA contractor who leaked classified information about the NSA’s mass surveillance programs, and who is currently living in exile in Russia. Snowden has publicly endorsed a legal defense fund for Roman Storm, which has raised over $350,000 so far. Snowden has also tweeted that “Privacy is not a crime”, and has urged the crypto community to help Storm and his co-developers.
Other organizations, such as Coin Center and the Blockchain Association, have also expressed their support for Tornado Cash and its co-founders, and have advocated for the recognition and protection of privacy rights in the crypto space. They have argued that Tornado Cash is not a money service business, and that it does not violate any laws or sanctions, as it does not have any control or knowledge over the funds or users that use its service.
What are the implications and outcomes of the case?
The case of Tornado Cash is one of the first and most significant legal challenges to the privacy-focused crypto sector, and it could have far-reaching implications and outcomes for the future of the industry and the technology. The case could set a precedent and a standard for how the U.S. and other governments regulate and prosecute crypto-related activities and actors, especially those that involve anonymity and encryption. The case could also affect the development and adoption of privacy-enhancing technologies and solutions, such as zero-knowledge proofs, mixers, and decentralized exchanges.
The case could also have an impact on the public perception and awareness of the crypto space, and its potential benefits and risks. The case could highlight the importance and value of financial privacy and innovation, and the need for more education and regulation in the crypto space. Alternatively, the case could reinforce the negative and hostile image and narrative of the crypto space, as a haven and a tool for criminals and enemies of the state.
The outcome of the case is uncertain and unpredictable, as it depends on various factors and variables, such as the evidence, the arguments, the jury, the judge, and the law. The case could result in a conviction, an acquittal, a plea deal, a dismissal, or a settlement. The case could also be appealed, or be subject to further legal action or intervention. Whatever the outcome, the case of Tornado Cash is likely to have a lasting and significant impact on the crypto space, and on the future of privacy and freedom in the digital age.
