Privacy-Preserving Payments on Constrained End-User Devices

Year: 2025

Type: conference-paper

Abstract: In this demo, we explore the resource demands of privacy-preserving digital payment systems based on digital tokens. We specifically focus on devices with constrained hardware resources. We evaluate our approach using GNU Taler, a free-software e-cash protocol and reference implementation, and RIOT, a free and open-source operating system for the IoT. Our preliminary findings suggest that participation in e-cash systems is feasible using inexpensive microcontrollers that have little processing, memory, and energy capabilities.
