Wallet Ecosystem for Business and payments Use cases on ldentification, Legal representation and Data

Johannes Sedlmeir, on behalf of the University of Münster, will support the architecture group (WP4) in the design and testing of wallet components. In particular, he will support the development of a roadmap towards a higher degree of protection of sensitive information by researching the state of the art in zero-knowledge proof technology, describing the tradeoffs between special-purpose (e.g., BBS) and general-purpose (e.g., NARKs) constructions, and how zero-knowledge proofs can be integrated into different architectural wallet designs.
