gGoogle’s ZKP system uses a blockchain-based cryptographic method that lets users prove facts like their age without disclosing how they know it or any personal details, ensuring privacy through encrypted proofs and public-key verification

Quotes that support claims

The ZKP cryptographic method lets someone prove a fact (like being over 18) without revealing how they know it or any more information.

This is done using a complex blockchain-based system that runs a condition (such as age) in an encrypted form, generating a proof, and letting an outside system verify it using public keys, ensuring privacy without exposing the underlying information.
