- Buenos Aires has launched a digital identity service referred to as QuarkID that makes use of zero-knowledge proofs
- The service allows privateness by verifying paperwork with out revealing private knowledge
- QuarkID will increase nationally, with pilots in different Argentinian areas underway
The metropolis of Buenos Aires has unveiled a ground-breaking digital identity service referred to as QuarkID, aimed toward enhancing residents’ privateness by superior cryptographic expertise often known as zero-knowledge proofs.
Integrated into the miBA app, a platform that has facilitated entry to municipal providers for the previous seven years, QuarkID seeks to offer roughly 3.6 million folks larger management over their private info.
Zero-knowledge proofs permit customers to confirm the authenticity of paperwork with out revealing pointless private knowledge. For occasion, residents can affirm their age when buying alcohol with out disclosing their full delivery date or deal with.

Users can add greater than 60 kinds of paperwork, together with delivery certificates and vaccination data, with further paperwork anticipated to be added within the coming months. Importantly, no third celebration, together with the municipality, has management over these paperwork, considerably mitigating the danger of information breaches.
The initiative guarantees to scale back prices for the federal government in comparison with conventional strategies of doc administration, and the pilot program is about to increase past Buenos Aires to areas like Jujuy and Tucumán, in addition to small cities comparable to Luján de Cuyo.
