Katrin Tinn/ Asymmetric Privacy in Digital Currency Design

Katrin Tinn's paper puts forward a theoretical model for digital currencies, including central bank digital currencies, incorporating asymmetric privacy. The author suggests this design would protect the privacy of spending while retaining the benefits of digital record-keeping for received funds. This feature is argued to reduce economic distortions and facilitate better tax optimisation and access to financing. Technologically, zero-knowledge proofs are mentioned as a possible implementation method.
