Peirce Pushes Zero-Knowledge Privacy for Regulators

SEC Commissioner Hester Peirce spoke at the SIFMA Digital Assets Conference in New York on September 23. She emphasized the need for financial regulators to adopt privacy-preserving cryptography that can verify customer eligibility without requiring institutions to collect sensitive personal information.

Peirce argued that zero-knowledge proofs could allow a counterparty to verify specific facts, such as age or accredited investor status, without seeing the underlying personal data. She called for regulators to move from prescriptive data collection toward attribute-based verification where technology makes it possible.

The current KYC and anti-money-laundering frameworks produce large stores of customer information across financial institutions. Customer Identification Programs can require names, birth dates, addresses, and identification numbers, while ongoing monitoring and regulatory reports add further transactional data. Peirce argued that duplicating those records increases exposure to accidental or deliberate data breaches without necessarily improving enforcement outcomes.

The SEC staff also issued guidance on September 25 clarifying token buybacks and staking receipts. For a functional crypto system, announcing a buyback of a non-security crypto asset does not constitute a promise to undertake the 'essential managerial efforts' considered under the Howey investment-contract analysis.
