Ever since the U.S. Treasury Department placed the Tornado Cash crypto mixer on the OFAC sanctions list, the cryptocurrency community has been in an uproar. The sanctions have brought about an existential debate regarding open-source code, free speech, citizens’ rights to financial privacy, the government’s right to sanction an entire technology instead of just the individuals who abuse it, and the potentially dangerous precedent the Treasury Department is setting for itself.
In August 2022, the U.S. Treasury Department declared sanctions on Tornado Cash and its users, sparking debate and outrage in the crypto community. The Treasury Department had already placed sanctions on Blender, a centralized crypto mixer service. However, Tornado Cash is not owned and operated by a centralized company like Blender was, and is an open-source Ethereum protocol governed by a decentralized autonomous organization (‘DAO’), a community of token holders who can submit proposals, add to the source code, and vote on changes to the Tornado Cash protocol they govern.
As CryptoDaily discusses, many prominent figures in the crypto community believe open-source code is protected free speech, and that the government does not have the right to place sanctions on an open-source technology. Several Coinbase employees and customers have since lost access to their crypto in the wake of the Tornado Cash sanctions, prompting the company to throw its massive financial weight into the class-action lawsuit that was filed against the Treasury Department in August. The privacy concerns around Web3 and blockchain technology are the official reason why crypto mixers exist at all, as there is currently no way to hide a user’s crypto holdings from other users, and discovering or leaking a crypto holder’s identity can place them or people connected to them in danger.
As reported by Blockworks, a contributor to the Tornado Cash open-source code was arrested in Amsterdam shortly after the sanctions were declared, which intensified the crypto community’s fervor in fighting back against the sanctions. They argue that if developers can be arrested and charged for contributing to open-source code that goes on to be used by hackers, crypto scammers, and criminals, then nobody who contributes to open-source projects is safe from the downstream effects of its use by criminals. Most internet technologies used today are open-source and are widely used for criminal activity on the dark web, leading many developers who have contributed to the internet’s open-source technologies to now question their safety and future.
Also troubling is the idea that sanctioning a collection of Ethereum smart contracts is akin to treating an entire technology as an individual, setting a dangerous precedent for all open-source technologies that are sometimes used for illicit activities, including the internet. There is historical precedent for the government trying to intervene against the internet’s development, as seen in the “Crypto Wars” of the 1990’s. The arguments used against internet cryptography back then were the same as those used against cryptocurrency mixers and ‘privacy coins’ today, citing their use in criminal activity. Today, cryptography over the internet is vital for protecting its users, but privacy protections don’t exist yet for public blockchains.
If sanctions can be placed on open-source projects for their downstream use in crime, it is plausible that sanctions could be placed on any open-source technology that is used for crime, such as the entire internet protocol or the world wide web’s source code. While sanctioning a tool often used for money laundering seemed like a step in the right direction, it has ultimately caused immense outrage from the cryptocurrency community for the same reasons the Crypto Wars of the ’90s caused outrage for the early internet era. The cryptocurrency community believes that open-source code is akin to free speech and developers should not be held responsible for how it is used by criminals, and that privacy is necessary for personal safety. With the class-action lawsuit mounted against the Treasury Department now funded by Coinbase, it remains to be seen if the Tornado Cash sanctions will remain in place.
