Google is rolling out a privacy-focused upgrade to its Wallet service that uses zero-knowledge proof (ZKP) technology for age verification, per a release.
The company said that the dating app Bumble, among others, will be one of the first partners to use this system. Bumble will use digital IDs issued through Google Wallet for user verification, while ZKPs will handle age confirmation.
The move allows users to prove they’re old enough to access certain apps or websites without revealing their birthdates or personal identifying data. ZKP is one of the biggest use cases for blockchains apart from real-world assets and payments, though it has yet to find popularity outside of niche circles.
Google said the system was developed in response to the growing number of services requiring age checks, from dating platforms to e-commerce and social media. “We wanted to develop a system that not only verifies age, but does it in a way that protects your privacy,” it said.
