政策法规的执行和审计机制的可用性是采用分布式支付系统的关键组成部分。在这项工作中，我们审查了一些现有的建议，分布式支付系统，提供某种形式的可验证性的监管机构。我们确定了两个主要的不同工作领域：不保护隐私的支付系统，如比特币，其中监管功能通常是为控制许多账户的组织量身定制的，以及保护隐私的支付系统，其中监管功能通常针对用户级别。我们提供了一个关于特征和性能的几个轴的系统化方法，同时强调了我们已经确定的见解和研究差距，例如监管机构和被审计实体之间缺乏争议解决方案，以及分类账修剪或链下协议与监管要求的不兼容性。根据我们的研究结果，我们提出了一些令人兴奋的未来研究方向。
Enforcement of policy regulations and availability of auditing mechanisms are crucial building blocks for the adoption of distributed payment systems. In this work we review a number of existing proposals for distributed payment systems that offer some form of auditability for regulators. We identify two major distinct lines of work: payment systems that are not privacy-preserving such as Bitcoin, where regulation functionalities are typically tailored for organizations controlling many accounts, and privacy-preserving payment systems where regulation functionalities are typically targeted to user level. We provide a systematization methodology over several axes of characteristics and performance, while highlighting insights and research gaps that we have identified, such as lack of dispute-resolution solutions between the regulator and the entity under audit, and the incompatibility of ledger pruning or off-chain protocols with regulatory requirements. Based on our findings, we propose a number of exciting future research directions.
