Tornado Cash got wrecked, and we could have prevented it

by Sophie Smith

The recent case involving Tornado Cash, a crypto mixer, has highlighted the growing attention from governments on regulating the crypto industry. The founders of Tornado Cash were charged with money laundering, and the case has influenced discussions around know-your-customer (KYC) and anti-money laundering (AML) regulations on crypto.

While some Web3 veterans may see this increased regulatory attention as a threat to the core ethos of Web3, it is essential to recognize that privacy and compliance do not have to be mutually exclusive. On-chain privacy has already been achieved through various cryptographic techniques, such as zero-knowledge proofs. These solutions have proven effective in retaining privacy.

However, there is a need to standardize best practices and establish safety standards across chains that align with national security interests and individual privacy needs. The Tornado Cash case serves as a reminder that Web3 users desire privacy, while regulators seek compliance. Although the outcome for Tornado Cash is unfavorable for Web3 privacy in the short term, it can lead to tangible actions that positively influence the industry in the long term.

To address the challenge of scaling privacy in the blockchain space, practical mechanisms are needed. One approach is the widespread adoption of zero-knowledge proofs, which enable data verification without exposing personal information. Other solutions include deposit screening, withdrawal screening, selective anonymization, and leveraging confidential computing.

While these strategies may not solve the overarching issue alone, when combined, they can increase the capacity to identify and disrupt illegal financial activity while protecting user data.

To prevent similar situations like Tornado Cash from happening again, continued development of privacy protocols is necessary. However, it is also crucial to preserve safety in a decentralized and permissionless manner. In order to scale privacy, it is important to step back from the microenvironments of Web3 and observe the larger regulatory landscape. Active participation in policy and regulatory development is crucial for the industry to future-proof itself.

Julian Deschler, Co-Founder of Elusiv, a universal encryption layer for Web3, emphasizes the need for industry leaders to work alongside policymakers, similar to how Big Tech companies lobbied for data privacy. Educating the next generation and fostering the future of privacy in Web3 is a shared responsibility.

As the industry moves forward, finding the balance between privacy and compliance will be crucial for the sustainable growth of the crypto ecosystem. By implementing practical mechanisms and collaborating with regulators, the industry can address privacy concerns while meeting regulatory requirements.
