Google is advancing user privacy in digital identity with a new zero-knowledge proof (ZKP) feature in its Wallet app, enabling users to confirm their age without revealing sensitive information such as birthdates or ID numbers.
The feature is designed for apps and services that require age verification, and it’s already being adopted by platforms like Bumble, which will use digital IDs issued through Wallet for onboarding and compliance. The system leverages ZKPs to confirm users meet age thresholds without exposing underlying data.
“Privacy and control over personal information are central to the digital ID experience we’re building,” Google said in a statement. “This upgrade allows for age verification that doesn’t compromise user trust.”
ZKP technology allows a user to prove they meet a requirement—such as being over 18—without showing how they meet it. Using blockchain-based verification and cryptographic proofs, the system protects user data while enabling platforms to remain compliant with age-related policies.
The feature is now live across Android devices and available to third-party developers via Google’s Digital Credential API.
With ZKP adoption now being led by a tech giant, the market is showing signs of renewed interest. According to CoinGecko, zero-knowledge sector tokens have risen by 1.7% in the last 24 hours, highlighting a potential resurgence in privacy-focused blockchain infrastructure.
