Buenos Aires to issue blockchain-based digital ID

cointelegraph.com:

Buenos Aires, the capital of Argentina, is making a major move toward integrating its bureaucracy with blockchain technology. Starting in October, the city's 15 million residents can access identity documents via a digital wallet, according to an announcement on Sept. 28. 

The first documents to be available on-chain include birth and marriage certificates, along with proof of income and academic verification. The announcement notes that health data and payment management will be integrated in the future, and that a roadmap for rolling out the blockchain-based solution across the country will be defined by the end of 2023.

Behind the project infrastructure is QuarkID, a digital identity protocol built by Web3 firm Extrimian. QuarkID wallets are powered by zkSync Era, an Ethereum scaling protocol using zero-knowledge rollups (ZK-rollups). The technology allows one party to prove to another that a statement is true, without revealing any specific information about the statement itself.

Data stored within the wallets will be self-sovereign, enabling citizens to manage the delivery of their credentials when interacting with government, businesses, and other individuals. zkSync Era will act as the settlement layer for QuarkID, ensuring that each citizen holds the correct
