Overview

Survey outlines privacy-preserving digital payment systems, highlighting privacy goals, implementations, and challenges for further research.

Key Points

  • The aim is to provide a comprehensive overview of privacy-preserving digital payment systems and their privacy goals.
  • Conducted a survey of decentralized ledger systems and central bank digital currencies (CBDCs).
  • Developed a taxonomy of privacy goals such as anonymity, confidentiality, unlinkability, and auditability.
  • Mapped privacy goals to their corresponding cryptographic primitives and protocols.
  • Outlined the evolution of privacy-preserving systems over three generations.
  • Identified trade-offs between privacy objectives and real-world auditability needs.
  • Highlighted critical challenges that require further research and architectural solutions.
