Zero-Knowledge Proofs for the European Digital Identity Framework (eID)
The European Union has had an ambivalent relationship with privacy, applying strict data protection regulations.
Last week, the EU Industry, Research, and Energy Committee approved using zero-knowledge proofs for the European digital identity framework (eID) amendments. This would grant EU citizens complete control of their data, allowing them to identify and authenticate themselves online without commercial providers, a press release states
The move could facilitate the emergence of new business models and opportunities in the digital economy while protecting citizens’ privacy.

Zero-knowledge proofs at the center of digital currencies’ regulatory compliance and privacy
Zero-knowledge proofs have recently gained attention from researchers as a possible means of ensuring regulatory compliance and privacy in digital currencies. A joint paper by the San Francisco-based Mina Foundation, German Hauck Aufhäuser Lampe bank, and the Interdisciplinary Centre for Security, Reliability, and Trust of the University of Luxembourg showed how zero proofs could be connected to Europe’s eIDAS electronic identity system.
However, only some are convinced that using proofs alone is sufficient for transactions that require personal information sharing, suggesting off-chain solutions are also needed.
