Context

A favorite solution to any problem for technologists is a Technology Solution regardless of whether that is the best way to solve the problem.

Problems

• Users have been unwilling to adopt any policy with such a high cognitive load as those available in 2019.

Solutions

• The paper Enhancing the Privacy of a Digital Pound (2024-12) describes 3 technologies

  This research showed that emerging types of PETs, like pseudonymization, zero-knowledge proofs, and secure multiparty computing, might feasibly be applied to digital currency systems such as the digital pound to minimize the sharing of data both with the central bank and between payment intermediaries, giving users greater control over their data and enhancing user privacy. This presents opportunities for a digital pound to be at least as private as current forms of digital money and potentially even more private, although as with any technology, there are limitations to what emerging types of PETs can achieve. Tensions may also emerge between regulations that require the disclosure of data and the latitude to deploy PETs that need to be addressed. Future technology research is likewise necessary to understand evolving risks associated with various technical limitations and potential regulatory constraints to the application of PETs.
