- Buenos Aires has launched a digital identification service known as QuarkID that makes use of zero-knowledge proofs
- The service permits privateness by verifying paperwork with out revealing private knowledge
- QuarkID will increase nationally, with pilots in different Argentinian areas underway
Town of Buenos Aires has unveiled a ground-breaking digital identification service known as QuarkID, geared toward enhancing residents’ privateness by means of superior cryptographic expertise often called zero-knowledge proofs.
Built-in into the miBA app, a platform that has facilitated entry to municipal providers for the previous seven years, QuarkID seeks to provide roughly 3.6 million individuals better management over their private data.
Zero-knowledge proofs permit customers to confirm the authenticity of paperwork with out revealing pointless private knowledge. As an illustration, residents can verify their age when buying alcohol with out disclosing their full start date or tackle.
This strategy is designed to empower residents by offering a self-sovereign identification system that prioritizes privateness and safety.
“The choice from the start was to create a self-sovereign identification system in order that residents can have privateness and safety over the paperwork they purchase possession of,” said Diego Fernandez, Buenos Aires’ secretary of innovation and digital transformation.
Whereas zero-knowledge proofs can operate independently of blockchain expertise, QuarkID makes use of the Ethereum layer-2 community ZKsync Period, which serves as a “safety anchor.” This ensures that knowledge might be confirmed to exist in a particular type at a particular time, thereby lowering the chance of identification theft and fraud.
Customers can add greater than 60 varieties of paperwork, together with start certificates and vaccination data, with further paperwork anticipated to be added within the coming months. Importantly, no third occasion, together with the municipality, has management over these paperwork, considerably mitigating the chance of knowledge breaches.
The initiative guarantees to cut back prices for the federal government in comparison with conventional strategies of doc administration, and the pilot program is ready to increase past Buenos Aires to areas like Jujuy and Tucumán, in addition to small cities comparable to Luján de Cuyo.
Fernandez emphasised the potential for nationwide scaling, stating that expertise developed in Buenos Aires could possibly be carried out all through Argentina and even in different Latin American nations, comparable to Uruguay.
