Today, we open sourced our Zero-Knowledge Proof (ZKP) libraries , fulfilling a promise and building on our partnership with Sparkasse to support EU age assurance . Open sourcing these powerful cryptographic tools will make it much easier for private and public sector developers to build their own privacy-enhancing applications and digital ID solutions, meeting an urgent need. In layperson’s terms, ZKP makes it possible for people to prove that something about them is true without exchanging any other data. So, for example, a person visiting a website can verifiably prove he or she is over 18, without sharing anything else at all. The goal of sharing ZKP with the open source and cryptography communities reflects our commitment to helping all parties in the ecosystem: Web and app users benefit from being inhabitants of a more private and secure digital ecosystem. Businesses and other relying organizations of all sizes can easily leverage this open source solution to meet their privacy needs.…
