Google Wallet Introduces Zero-Knowledge Proofs for Enhanced Privacy
Google is enhancing Google Wallet with zero-knowledge proofs (ZKPs). This feature lets users prove their age on websites without sharing personal data like birthdates. It’s a big move towards making crypto identity tools user-kind.
Rob Viglione, co-founder of Horizen labs, sees this as a meaningful step.”When big tech companies adopt ZKPs, it shows privacy innovations are going mainstream,” he noted. ZKPs allow age verification without exposing sensitive facts.
How does it work? Users can confirm they meet age requirements for services like Bumble or alcohol purchases. They only reveal if they’re old enough, not their exact age.This protects user privacy. Viglione believes this trend will push the industry towards more privacy-focused solutions.
Google’s move is a game-changer for privacy.
Google Wallet’s Digital Credential API uses ZKPs for age verification. Users can prove they’re old enough for certain services without revealing personal details. This protects their privacy.
Google plans to open source its ZKP technology. This will help other wallets and services adopt privacy-preserving features. The new functionality is rolling out alongside an expansion of digital IDs in more U.S. states, the U.K., and 50 additional countries.
Viglione called this shift long overdue. “Privacy shouldn’t be a luxury or an afterthought—it should be a default,” he said. “It’s exciting to see leading companies recognise that.”
