SEC’s Peirce Urges Zero-Knowledge Proofs to Reduce KYC Data Collection

Each sentence links inside to the piece that supports it.

Users and customers who have to hand over identity information for KYC checks are the most directly affected, because the speech points to compliance methods that can verify eligibility while sharing less personal data. Regulators and firms handling identity checks also have to notice that the proposal is about replacing data-heavy collection with cryptographic verification, not ending compliance requirements themselves.

In practice, the change is that attribute-based credentials and zero-knowledge proofs are presented as usable tools for identity and eligibility checks instead of broader personal-data collection. What stays the same is the need to verify compliance for KYC and AML, since the speech still frames the issue as a way to do those checks with less information exposure.

Still unknown is how broadly regulators would adopt these methods or how they would be implemented across the financial system, because the speech is a call for more cryptographic privacy rather than a rule. What would settle that is a formal regulatory proposal or adopted standard that specifies when zero-knowledge proofs or similar credentials can be used.

We track DATA, but we only have 0 price points in that window. The series is stored every half hour, so newer events will have it. Computing it from two points would not be a reaction, it would be a coincidence.
