Buenos Aires, the capital of Argentina, has officially launched a blockchain-based digital ID system called QuarkID.
This initiative is a major global milestone in decentralized #ID and the first government-backed deployment of such technology.
The system uses zero-knowledge cryptography via ZKsync Era, a layer 2 #etherium network. The system is integrated into the city's MiBa platform, a seven-year-old application for accessing municipal services and documents.
QuarkID allows residents to securely manage and share documents such as birth certificates, tax records and vaccination data without revealing unnecessary personal information.
Diego Fernández, Minister of Innovation and Digital Transformation of the City of Buenos Aires, emphasized that the use of zero-knowledge technology allows residents to take responsibility for their personal data, increasing the level of confidência The system has no cost to the user and reduces government spending compared to traditional methods.
This pioneering work by Buenos Aires sets a precedent for other cities and governments to explore #blockchain technology to improve their digital identity systems.
