Buenos Aires has become the first major capital to implement a large-scale blockchain-driven digital identity system, launching QuarkID to provide decentralized digital identities (DIDs) for over 3.6 million residents. This new system integrates with the city’s miBA mobile app and shifts from traditional centralized identity frameworks to a self-sovereign identity (SSI) model. Utilizing advanced technologies like zero-knowledge cryptography and the ZKsync Layer 2 blockchain, QuarkID allows individuals to control their personal data independently, enhancing both security and privacy.
QuarkID enables residents to manage a range of digital credentials, such as birth certificates, marriage licenses, proof of income, and academic records, without relying on centralized oversight. Users decide how their credentials are shared and used, with plans to expand support for health data and payment information in the future. This approach is designed to empower citizens while protecting their privacy.
The launch follows a successful pilot phase during Aleph, a local crypto-focused event, where participants used QuarkID for secure transactions and identity verification. The implementation was a collaborative effort with Extrimian, a company specializing in decentralized digital identity solutions. QuarkID adheres to international standards set by the World Wide Web Consortium (W3C) and Trust Over IP, ensuring the system aligns with global best practices for secure digital identity management.
Recognized as a Digital Public Good by the United Nations, QuarkID’s development aligns with Sustainable Development Goals, aiming to influence global digital identity trends. By decentralizing digital credentials, the system enhances security and privacy while granting citizens full control over their data.
