摘要

摘要: 数字货币(Digital currency)作为区块链技术迄今为止最典型也最成功的应用, 得益于区块链分布式共识与去中心化信任的技术优势, 也促使了区块链技术与经济活动的深度融合, 并由此改变了数字社会的组织方式. 近年来, 无论是在基础理论研究方面, 还是在实践应用发展方面, 数字货币均呈现出了蓬勃向上的态势. 本文从技术创新、机制设计以及风险监管三个角度梳理了数字货币的主要研究问题, 详细阐述了基础支撑技术、隐私保护技术、共识机制、激励机制、币值机制、发行机制、风险分析、监管考量等方面的研究进展、存在问题及应用现状, 并展望了未来重点研究方向, 致力于为数字货币领域的研究提供有益借鉴.

Abstract: As the most representative and successful application of blockchain technology, digital currency benefits from the technical advantages of distributed consensus and decentralized trust in blockchain, and also promotes the deep integration of blockchain technology and economic activities, thus changing the organization mode of digital society. Recently, digital currency has shown a booming trend both in theoretical researches and practical applications. In view of this, our paper discusses the main research issues of digital currency from three perspectives, including technological innovation, mechanism design and risk regulation, and elaborates the research progress, existing problems and application status of basic technology, privacy protection technology, consensus mechanism, incentive mechanism, value mechanism, issuance mechanism, risk analysis, regulatory considerations, etc., and puts forward the main emphasis of the future researches. Our work is devoted to providing useful reference and good support for the future research in the field of digital currency.
