标题： Quantum-Resilient Privacy Ledger (QRPL): A Sovereign Digital Currency for the Post-Quantum Era

摘要： 量子计算的出现对现有的密码基础设施提出了深刻的挑战，同时中央银行数字货币（CBDCs）的发展引发了关于数字支付系统中隐私保护和过度集中化的担忧。 本文提出了量子抗性隐私账本（QRPL），这是一种创新的基于代币的数字货币架构，结合了国家技术标准局（NIST）标准化的后量子密码学（PQC）与基于哈希的零知识证明，以确保用户主权、可扩展性和交易机密性。 主要贡献包括为不可链接交易适应短暂证明链，一种隐私加权的权益证明（PoS）共识以促进公平参与，以及一种基于零知识证明的隐私保护选择性披露机制。 QRPL旨在解决现有CBDC设计中的关键缺陷，包括普遍监控的风险，并通过10-20秒的区块时间在未来的货币系统中平衡安全性和吞吐量。 虽然概念上是初步的，但计划进行实证原型。 未来的工作包括开发原型以实证验证这些模型。 显示英文摘要

摘要： The emergence of quantum computing presents profound challenges to existing cryptographic infrastructures, whilst the development of central bank digital currencies (CBDCs) has raised concerns regarding privacy preservation and excessive centralisation in digital payment systems. This paper proposes the Quantum-Resilient Privacy Ledger (QRPL) as an innovative token-based digital currency architecture that incorporates National Institute of Standards and Technology (NIST)-standardised post-quantum cryptography (PQC) with hash-based zero-knowledge proofs to ensure user sovereignty, scalability, and transaction confidentiality. Key contributions include adaptations of ephemeral proof chains for unlinkable transactions, a privacy-weighted Proof-of-Stake (PoS) consensus to promote equitable participation, and a novel zero-knowledge proof-based mechanism for privacy-preserving selective disclosure. QRPL aims to address critical shortcomings in prevailing CBDC designs, including risks of pervasive surveillance, with a 10-20 second block time to balance security and throughput in future monetary systems. While conceptual, empirical prototypes are planned. Future work includes prototype development to validate these models empirically.
