a16z Crypto has submitted its initial feedback on the implementation phase of the GENIUS Act to the U.S. Treasury, recommending the use of privacy-enhancing decentralized digital identities to improve compliance and security. The firm urges FinCEN to update anti-money laundering (AML) and KYC regulations to allow financial institutions to use cryptographic technologies like zero-knowledge proofs (ZKP) for identity verification while preserving privacy. Additionally, a16z emphasizes the need to clearly distinguish between "decentralized stablecoins" and "payment stablecoins" to foster fair competition and a technology-driven regulatory framework, ensuring the GENIUS Act strengthens the dollar's position while unleashing innovation potential.
