SEC Commissioner Hester Peirce is calling on financial institutions to adopt zero-knowledge proofs and reuse previously verified identity credentials, a proposal aimed at shrinking the personal-data footprint created by routine know-your-customer (KYC) onboarding, The Defiant reported.

Peirce's framework targets the redundancy baked into the current KYC system. Banks, brokerages, and crypto platforms each collect their own copy of customer documentation, building parallel stores of passports, proof-of-address records, and biometric captures. The accumulated data raises breach exposure for both firms and end users.

What does the proposal change?

The commissioner wants institutions to accept cryptographic attestations from prior, verified KYC checks rather than re-collect the same artifacts at every touchpoint. A user cleared by one regulated firm would present a zero-knowledge proof to a second institution, allowing that institution to confirm the user's verified status without ever receiving the underlying personal data.

The shift would not relax anti-money-laundering or counter-terrorist-financing obligations. "Her privacy proposals do not change existing compliance rules," The Defiant noted. Firms must still satisfy KYC standards even if they stop holding the raw documentation themselves.

Why does this matter for crypto firms?

Re-verifying users across centralized exchanges, custodians, lending desks, and fiat on-ramps inflates onboarding costs and concentrates data-breach liability inside the sector. Each new venue a customer accesses multiplies the copies of their identity on file.

Zero-knowledge proofs already support selective credential disclosure in decentralized-identity projects, but U.S. financial institutions have lagged in adopting these tools. A formal endorsement from a sitting SEC commissioner would lift the profile of ZK-based KYC in compliance conversations, particularly for firms operating at the intersection of traditional finance and digital assets.

Who is Hester Peirce?

Peirce joined the SEC in 2018 and has emerged as the agency's most vocal advocate for a clearer, less enforcement-driven approach to digital-asset regulation. She has publicly criticized the commission's reliance on enforcement actions in lieu of formal rulemaking, a posture that has made her a frequent reference point for the industry's calls for structural reform.

Her latest remarks extend that stance into the privacy domain, framing data minimization as a security and compliance improvement rather than a regulatory concession.

What are the limits of the proposal?

The plan carries no immediate regulatory force. A single commissioner cannot impose new rules; a majority of the five-member commission would need to back any binding measure. Practical questions also remain: a bank that runs its own compliance program may still demand full documentation regardless of any cryptographic attestation, and the legal status of ZK-based proofs in U.S. supervisory examinations is unresolved.

Regulators would also need assurance that any third-party verification relied upon by a covered institution meets the same standard as in-house KYC, a question that has not been adjudicated in U.S. law.

What happens next?

The Defiant's report did not specify a date for Peirce's written statement. Market participants should watch for follow-up language in upcoming commissioner speeches, dissenting statements, and rule-comment letters as the SEC works through its 2025 agenda.
