摘　　要：近年来,分布式数字资产交易平台(decentralized digital asset exchanges,DDAE)受到了广泛的关注.基于金融市场基础设施(principles for financial market infrastructures,PFMI)原理,提出了评估数字资产交易平台的5项基本原则.并基于这些原则,从通信技术和交换协议技术两个方面对现有的分布式数字资产交易平台进行了讨论和评估,阐述了几种典型技术解决方案的实施原理,将各种技术归纳为不同的模型进行分析.然后讨论了当前分布式数字资产交易平台存在的监管问题,并针对之前监管中出现的监管数据不完整和数据被篡改的问题,提出一种分布式监管模型,该模型由区块链系统、监管执行引擎以及监管法规库这3部分组成,能够通过读取区块链中的交易数据进行分析,自动执行监管法规库中的规则,对满足监管规则的交易自动生成监管报告,从而实现自动化监管.最后,对分布式数字资产交易平台的发展进行了总结和展望.Recently,decentralized digital asset exchanges(DDAE)have received significant attention.This study proposes five criteria to evaluate DDAE based on the principles of financial market infrastructure(PFMI).The current DDAEs technologies are discussed and evaluated from two aspects of inter-blockchain communication(IBC)and exchange protocol technology,the implementation principles of several typical technical solutions are elaborated,and various technologies are summarized into different models for analysis.Then,the regulatory issues of current DDAEs are discussed,and a distributed supervision modelis proposed for the problems of incomplete supervision data and data tampering.This model consists of three parts:Blockchain system,supervision execution engine,and supervision regulation database,which can automatically executethe supervision rules in the supervision regulation database by reading the transaction data in the blockchain and automatically generate the supervision report for the transactions meeting the supervision rules.Finally,the development of DDAEs is summarized and anticipated.
