According to CoinMeta, specialist Hester Peirce calls for an end to large-scale KYC data collection, warning that it exposes crypto holders to the risks of phishing and personal attacks. Peirce states that the current KYC / AML systems have created a large number of sensitive information databases that could be hacked, leaked, or exploited. She is advocating for the use of zero-knowledge proofs (zk proofs) to verify that users meet regulatory requirements without exposing their personal information.
