Buenos Aires adds blockchain-based IDs to city app for privacy purposes

by

As a seasoned crypto investor and privacy advocate, I find Buenos Aires’ adoption of QuarkID and ZK technology truly groundbreaking. Having witnessed numerous data breaches and identity theft incidents across various centralized systems, it’s refreshing to see a city taking proactive steps towards securing its citizens’ personal information.

Argentine capital, Buenos Aires, is rolling out a novel digital identity system emphasizing privacy by leveraging cutting-edge zero-knowledge technology.

In simple terms, the government of Argentina has incorporated QuarkID, a blockchain-powered identity system, into their miBA mobile application. This app caters to more than 3.6 million locals and provides them with various services and documents, as reported in a press statement by Chainwire.

On October 1, 2024, this innovative project made its debut, making Buenos Aires the pioneering city globally to implement Zero-Knowledge (ZK) technology for handling decentralized digital identities.

Presenting QuarkID empowers residents to take charge of their own personal data, providing them the ability to handle important documents such as birth certificates and tax records directly from their smartphones.

Buenos Aires and ZK technology

The key innovation here is zero-knowledge cryptography, which enables users to verify information without revealing unnecessary personal details. 

zero-knowledge tech, a cryptographic method, guarantees privacy through sharing minimal necessary information during authentication procedures. To put it simply, this implies that private details stay secure throughout transactions, and neither external parties like governments nor other entities can trace when or how these credentials are employed.

This differs from traditional systems, where institutions often manage and store users’ data.

In simpler terms, the structure of QuarkID’s blockchain operates on the ZKsync Era platform, boosting both security and transparency. This is because personal information is kept in a distributed network rather than a single point, thereby minimizing threats such as data leaks and identity theft, as stated in the announcement.

Buenos Aires intends to broaden the scope of the system to include additional types of documents like driver’s licenses and public permits.

As an analyst, I’ve had the opportunity to be part of the team that has successfully piloted our innovative solution, QuarkID, not just within the United States, but also in neighboring countries such as Mexico, Colombia, and Peru. We have ambitious plans for its further growth, with Argentina being our next target for expansion.
