Buenos Aires has partnered with blockchain platform ZKSync to launch a new digital identity system. This initiative will provide 3.6 million citizens with blockchain-based digital IDs, allowing them to securely access over 60 types of documents, including birth certificates, driver’s licenses, and tax records.

The new system, called QuarkID, builds on the city’s existing digital identity platform, miBA, by integrating zero-knowledge cryptography. This advanced blockchain technology ensures that personal data is protected and kept off government servers, boosting both privacy and security for users.

Announced on October 22, the collaboration with ZKSync underscores Buenos Aires’ commitment to leveraging cutting-edge technologies in government services. Jorge Macri, Chief of Government for the City of Buenos Aires, highlighted that this initiative places the city at the global forefront of digital innovation.

“The incorporation of zero-knowledge blockchain technology into the City’s digital identity system is a fundamental step toward more secure and transparent digital solutions,” Macri stated.

This digital ID program marks a significant step in Argentina’s growing Web3 adoption, which has accelerated since pro-Bitcoin candidate Javier Milei’s presidential election victory. Buenos Aires is rapidly becoming a hub for blockchain and cryptocurrency advancements, and the introduction of QuarkID is a natural extension of these efforts.

For ZKSync, this partnership presents an opportunity for recovery following a period of low activity. By mid-2024, the platform had seen a 66% decline in active addresses, and its native ZK token experienced a prolonged slump. The high-profile collaboration with Buenos Aires could help ZKSync regain momentum and enhance its standing in the blockchain sector.

QuarkID, now available to all miBA users, promises a seamless experience for citizens while providing significant backend improvements. The platform’s trustless blockchain architecture ensures that sensitive information remains secure, with zero-knowledge technology preventing unauthorized access.

Through QuarkID, Buenos Aires is taking bold steps toward digital transformation. The platform offers a wide range of services, from obtaining marriage and death certificates to accessing vaccine records. With ZKSync’s blockchain technology, citizens can securely manage their personal data without compromising privacy.

The collaboration between Buenos Aires and ZKSync reflects Argentina’s broader ambition to integrate blockchain technology into public services. By prioritizing security, transparency, and privacy, the city is setting a new standard for digital governance in the region.
