The Eroding State of Privacy in the Crypto World

Crypto’s Battle for Privacy Intensifies in Face of Regulatory Clampdown

The crypto industry is at a turning point, with the tension between privacy and regulatory oversight becoming increasingly pronounced. As regulators continue to clamp down, the industry’s response and innovations will likely shape the future trajectory of cryptocurrency. The ongoing developments and debates around privacy will be critical in determining whether the crypto industry can retain its core ethos or if it will transform under the weight of external pressures.

Crypto Under Attack

Arguably, the first major move against crypto privacy happened on August 9 2022 when U.S. Office of Foreign Assets Control (OFAC) imposed sanctions on the ethereum mixing application Tornado Cash, citing its role in aiding North Korean hackers, specifically the Lazarus Group. The sanctions extended to both Tornado Cash and Tornado Cash Classic websites and included numerous associated cryptocurrency addresses, which have now been added to OFAC’s Specially Designated Nationals (SDN) list, effectively prohibiting all U.S. persons and entities from interacting with them.

Privacy coins have been under attack by less direct actions, for example, by putting pressure on exchanges to de-list privacy coins for compliance reasons. Monero experienced a significant 32% drop in market value after Binance announced its removal from the platform effective February 20, 2024, citing non-compliance with the exchange’s listing standards. This decision followed a similar move by Okx in December and affected not only Monero but also other cryptocurrencies like ANT, MULTI, and VAI.

Most recently, the U.S. Department of Justice indicted Keonne Rodriguez and William Lonergan Hill, the founders of Samourai Wallet, on charges of running an unlicensed money-transmitting business and laundering over $100 million. The indictment, issued by the Southern District of New York, claims that Samourai Wallet processed over $2 billion in transactions as a cryptocurrency mixer without regulatory oversight, facilitating large-scale money laundering activities.

Crypto Fights Back

In response to the escalation of government attacks on privacy, notable figures in and around crypto have voiced their concerns and in some cases begun to take actions. Pavel Durov, founder of Telegram, expressed concerns over governments’ growing intolerance towards privacy due to enhanced technological powers. Durov predicts that this will lead to the development of secure communication devices similar to cryptocurrency hardware wallets. He gave examples of attempts by the FBI to install backdoors in Telegram for surveillance.

American whistleblower Edward Snowden recently issued a warning about the imminent expansion of the NSA’s surveillance powers, suggesting that the agency is close to “taking over the internet.” This concern was raised following comments by Elizabeth Goitein, co-director of the Liberty and National Security Program at the Brennan Center for Justice, who highlighted a subtle modification in the Foreign Intelligence Surveillance Act (FISA) 702 bill. This change could significantly broaden the NSA’s reach, potentially requiring almost all entities involved in providing internet-related services to participate in NSA surveillance activities.

Vitalik Buterin, Ethereum’s co-founder, actively endorsed on-chain privacy, engaging with privacy protocols like Railgun to demonstrate the practicality of private transactions. Buterin’s advocacy followed his transfer of 100 ETH to Railgun, which was reported to enhance privacy in decentralized finance ( defi) transactions. Railgun’s privacy protocol, noted for making it difficult for malicious actors to compromise user privacy, has been seen as a key alternative to Tornado Cash, especially after Tornado was sanctioned by the US Treasury.

Meanwhile, Coinbase Legal Chief Paul Grewal has publicly supported Tornado Cash in its ongoing legal battle with the U.S. Treasury over allegations of money laundering. In a statement, Grewal detailed Tornado Cash’s legal arguments, explaining that the Treasury’s claim under the International Emergency Economic Powers Act (IEEPA) is unfounded because the code does not meet the statutory requirements to be considered “property” under the act. Despite Coinbase’s support and a strong legal stance, a judge dismissed the case, stating that the Treasury has the constitutional right to enforce sanctions against Tornado Cash, rejecting the argument that smart contracts are not property because they are immutable.

Legal stands for privacy like those of Coinbase are important, but crypto projects must also fight against governmental encroachment through their products. Privacy-focused projects like Zano blockchain are crucial.

The Zano blockchain recently completed its Zarcanum hard fork (HF4), significantly enhancing its capabilities by allowing users and organizations to create untraceable custom tokenized or confidential assets, advancing the chain’s transformation from a single-asset to a multi- privacy coin platform. This development was described as a groundbreaking commencement rather than an endpoint by co-founder Pavel Nikienkov.

With governments seeming to focus more on removing privacy, this quote from Zano community manager Quinten van Welzen regarding the importance of privacy in the drive to increase cryptocurrency adoption seems more likely every day:

Privacy is necessary if cryptocurrencies ever want to become globally adopted. Without privacy, a currency can’t be fungible. Prime examples are the blacklisting of certain cryptocurrencies that have been involved with illegal activities, making these specific assets worth less than the ones that are considered ‘clean.’
