Buenos Aires has taken a significant step forward in privacy protection and identity verification by introducing the digital service QuarkID using zero-knowledge proofs.

Introduction to QuarkID

QuarkID is a state-of-the-art digital identity service developed by the Buenos Aires government to enhance security and privacy for residents. Utilizing zero-knowledge proofs (ZKP), QuarkID allows identity and document authenticity verification without disclosing personal data, protecting against potential breaches and misuse.

How QuarkID Works

QuarkID operates on the Ethereum layer-2 network ZKsync Era, utilizing ZK-rollups to increase transaction throughput and reduce costs. It provides secure and efficient verification for over 60 document types, including national ID cards, passports, driver's licenses, and more, making it a versatile tool for various applications.

Integration into the miBA App

The miBA app, Buenos Aires' digital platform, has integrated QuarkID to enhance functionality and offer residents a secure way to verify documents. Users benefit from seamless verification, enhanced security, and convenience, reducing the need for in-person visits to government offices.

The launch of QuarkID in Buenos Aires marks a pivotal step in digital identity verification, showcasing the benefits of using modern cryptographic methods. The system reduces identity theft risks and improves government service efficiency, with prospects for expansion to other regions in Argentina and Latin America.
