Google Integrates Zero-Knowledge Proofs Into Wallet for Privacy-Preserving Age Verification

Google has announced the integration of zero-knowledge proofs (ZKPs) into its Wallet app, enabling users to verify their age online without revealing personal details such as birthdates. This new privacy feature, part of Google's Digital Credential API, targets services requiring age verification, like online alcohol purchases and dating apps. The move signals mainstream recognition of cryptographic privacy tools. Rob Viglione of Horizen Labs applauded the announcement, highlighting its significance for privacy-focused blockchain projects. Google also plans to open source its ZKP technology, encouraging broader adoption among digital wallets and other services. The rollout coincides with the expansion of digital IDs in additional states and countries.
