 Buenos Aires to issue blockchain-based digital identity

Argentina's capital Buenos Aires is taking a big step towards connecting its bureaucracy with blockchain technology. Because from October, city residents can access identity documents through digital wallet. Documents available on the chain will currently include birth and marriage certificates as well as proof of income and educational verification. Additionally, health data and payment management will be added in the future and a roadmap to roll out blockchain-based solutions across the country will be defined by the end of 2023. With this development, Buenos Aires becomes the first city in Latin America and one of the few in the world to integrate and promote this new technology, setting the standard for other countries in the region to take advantage of. How should blockchain technology be used.

Behind the infrastructure of this project is QuarkID, a digital identity protocol created by Web3 firm Extrimian. QuarkID wallets are powered by zkSync Era, an Ethereum scaling protocol using zero-knowledge rollups. This technology allows one party to prove that a statement is true without giving the other party any specific information about the statement.

Data stored in the wallet will be self-sovereign, enabling citizens to manage the delivery of their information when interacting with governments, businesses, and other individuals. ZkSync Era will act as the settlement layer for QuarkID and ensure that every citizen has the correct credentials.

Worldcoin is also in discussion in Argentina

Argentine authorities are investigating a similar initiative in the country, digital ID project Worldcoin. In August local authorities revealed that an investigation had been conducted over privacy concerns related to Worldcoin's collection, storage and use of customer data. In fact, last month Worldcoin had set a new record in Argentina. While in Argentina an astonishing 9,500 people verified World IDs in a single day, on average approximately one ID was verified every 9 seconds. This is a record so far. Apart from this, Worldcoin is also under investigation in Europe and Africa since its global launch in July. Founded by OpenAI co-founder Sam Altman, the project uses retina scans to verify users.
