For instance, residents can confirm their age when purchasing alcohol without disclosing their full birthdate or address.<\/p>\n<p>This approach is designed to empower citizens by providing a self-sovereign identity system that prioritizes privacy and security. \u201cThe decision from the beginning was to create a self-sovereign identity system so that citizens can have privacy and security over the documents they acquire ownership of,\u201d stated Diego Fernandez, Buenos Aires\u2019 secretary of innovation and digital transformation.<\/p>\n<p>While zero-knowledge proofs can function independently of blockchain technology, QuarkID utilizes the <a href=\"https:\/\/coinjournal.net\/ethereum\/what-is-ethereum\/\">Ethereum<\/a> layer-2 network ZKsync Era, which serves as a \u201csecurity anchor.\u201d This ensures that data can be proven to exist in a specific form at a specific time, thereby reducing the risk of identity theft and fraud.<\/p>\n<p>Users can upload more than 60 types of documents, including birth certificates and vaccination records, with additional documents expected to be added in the coming months. Importantly, no third party, including the municipality, has control over these documents, significantly mitigating the risk of data breaches.<\/p>\n<p>The initiative promises to reduce costs for the government compared to traditional methods of document management, and the pilot program is set to expand beyond Buenos Aires to regions like Jujuy and Tucum\u00e1n, as well as small towns such as Luj\u00e1n de Cuyo.<\/p>\n<p>Fernandez emphasized the potential for national scaling, stating that technology developed in Buenos Aires could be implemented throughout Argentina and even in other Latin American countries, such as Uruguay.<\/p>\n<div class=\"post-meta\">\n<hr class=\"mb-6\"\/>\n<h6 class=\"text-3xl  mb-4  text-green-300\">Share this article<\/h6>\n<hr class=\"mb-6\"\/>\n<h6 class=\"text-3xl  mb-4  text-green-300\">Categories<\/h6>\n<hr class=\"mb-6\"\/>\n<h6 class=\"text-3xl  mb-4  text-green-300\">Tags<\/h6>\n<\/p><\/div>\n<\/p><\/div>\n<p><a href=\"https:\/\/coinjournal.net\/news\/buenos-aires-launches-quarkid-a-digital-identity-service-using-zk-proofs\/\">Source link <\/a><br \/>\n<br \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>(Originally posted on : CoinJournal: Latest Crypto News, Altcoin News and Cryptocurrency Comparison ) Buenos Aires has launched a digital identity service called QuarkID that uses zero-knowledge proofs.
