The crypto-focused investment arm of venture capital firm Andreessen Horowitz (a16z) points out that modern crypto technologies such as zero-knowledge proofs can both protect user privacy and allow law enforcement to effectively crack down on criminals. In a report released on Tuesday, Aiden Slaven, policy partner at a16z Crypto, and David Sverdlov, regulatory counsel, said zero-knowledge proofs could verify the authenticity of data without revealing any detailed private information. They believe that this technology has "the greatest potential" by showing the origin of funds without having to disclose private information.
The report comes just two weeks after Roman Storm, co-founder of cryptocurrency mixing service TornadoCash, was found guilty of allowing users to hide the origin and whereabouts of cryptocurrencies, and of conspiracy to operate an unlicensed money transfer business.
In the Tornado Cash case, law enforcement and prosecutors argued that the service facilitated criminal activity by providing a means to conceal ill-gotten gains. "If a user can provide such proof when converting a cryptocurrency into fiat, then a cash exchange point can obtain reasonable assurance that the cryptocurrency is not derived from the proceeds of crime, while retaining the privacy of their on-chain transactions," Slaven and Sverdlov said in their report.
