## Description

Howard Wu, CEO of Provable, discusses the challenges of current online identity and age verification methods, highlighting privacy risks such as oversharing personal data, lack of revocation, and data breaches. He introduces zero-knowledge proofs (ZKPs) as a privacy-preserving solution, enabling users to prove attributes (e.g., age, residency, group membership) without revealing sensitive information.

Wu presents ZPass, a verifiable credentials system leveraging ZKPs for selective disclosure, and KYA (Know Your Address), which uses ZKML for on-device facial verification to prove ongoing humanity and identity ownership. These tools aim to enable compliance and privacy for onchain and web3 applications, supporting private stablecoins and payments while minimizing data exposure. Wu emphasizes the need for regulatory engagement and evolving compliance tech to match privacy advancements.
