Abstract

Decentralized Anonymous Payment Systems (DAP), often known as cryptocurrencies, stand out as some of the most innovative and successful applications on the blockchain. These systems have garnered significant attention in the financial industry due to their highly secure and reliable features. Regrettably, the DAP system can be exploited to fund illegal activities such as drug dealing and terrorism. Therefore, governments are increasingly worried about the illicit use of DAP systems, which poses a critical threat to their security. This paper proposes Privacy and Compliance in Regulated Anonymous Payment System Based on Blockchain (PCRAP), which provides government supervision and enforces regulations over transactions without sacrificing the essential idea of the blockchain, that is, without surrendering transaction privacy or anonymity of the participants. The key characteristic of the proposed scheme is using a ring signature and stealth address to ensure the anonymity of both the sender and receiver of the transaction. Moreover, a Merkle Tree is used to guarantee government supervision and enforce regulations. Our proposed scheme satisfies most of the stringent security requirements and complies with the standards of secure payment systems. Additionally, while our work supports government regulations and supervision, it guarantees unconditional anonymity for users. Furthermore, the performance analysis demonstrates that our suggested scheme still remains applicable and effective even when achieving complete anonymity.

基于区块链的受监管匿名支付系统的隐私与合规性
去中心化匿名支付系统(DAP)通常被称为加密货币,是区块链上最具创新性和最成功的应用之一。这些系统因其高度安全可靠的特点而在金融业备受关注。遗憾的是,DAP 系统可能会被用于资助贩毒和恐怖主义等非法活动。因此,各国政府越来越担心 DAP 系统被非法使用,这对其安全构成了严重威胁。本文提出了基于区块链的受监管匿名支付系统(PCRAP)中的隐私与合规性,在不牺牲区块链的基本思想,即不放弃参与者的交易隐私或匿名性的前提下,提供政府监督并对交易实施监管。拟议方案的主要特点是使用环形签名和隐身地址来确保交易发送方和接收方的匿名性。此外,梅克尔树(Merkle Tree)用于保证政府的监督和法规的执行。我们提出的方案满足了大多数严格的安全要求,符合安全支付系统的标准。此外,我们的工作在支持政府法规和监督的同时,还保证了用户的无条件匿名性。此外,性能分析表明,即使在实现完全匿名的情况下,我们建议的方案仍然适用且有效。
