The Financial system has witnessed rapid technological changes. The rise of Bitcoin and other crypto assets based on Distributed Ledger Technology mark a fundamental change in the way people transact and transmit value over a decentralized network, spread across geographies. This has created regulatory and tax policy blind spots, as governments and tax administrations take time to understand and provide policy responses to this innovative, revolutionary, and fast-paced technology. Due to the breakneck speed of innovation in blockchain technology and advent of Decentralized Finance, Decentralized Autonomous Organizations and the Metaverse, it is unlikely that the policy interventions and guidance by regulatory authorities or tax administrations would be ahead or in sync with the pace of innovation. This paper tries to explain the principles on which crypto assets function, their underlying technology and relates them to the tax issues and taxable events which arise within this ecosystem. It also provides instances of tax and regulatory policy responses already in effect in various jurisdictions, including the recent changes in reporting standards by the FATF and the OECD. This paper tries to explain the rationale behind existing laws and policies and the challenges in their implementation. It also attempts to present a ballpark estimate of tax potential of this asset class and suggests creation of global public digital infrastructure that can address issues related to pseudonymity and extra-territoriality. The paper analyses both direct and indirect taxation issues related to crypto assets and discusses more recent aspects like proof-of-stake and maximal extractable value in greater detail.

翻译：金融体系正经历快速的技术变革。基于分布式账本技术的比特币及其他加密资产的崛起，标志着人们在跨越地域的去中心化网络上进行交易和价值传递的方式发生了根本性转变。由于各国政府及税务管理部门需要时间理解并制定政策应对这一创新性、革命性且发展迅猛的技术，这造成了监管与税收政策的盲区。鉴于区块链技术创新的高速发展以及去中心化金融、去中心化自治组织及元宇宙的出现，监管机构或税务管理部门的政策干预与指导很难超越或同步于创新步伐。本文旨在阐释加密资产的运行原理及其底层技术，并将其与生态系统中产生的税务问题及应税事件相关联。同时，文中列举了各司法管辖区已生效的税收与监管政策实例，包括金融行动特别工作组与经济合作与发展组织近期在报告标准方面的变化。本文试图解析现有法律与政策的制定逻辑及实施中面临的挑战，并对该类资产的税收潜力进行粗略估算，提出构建能解决化名性与域外性问题的全球公共数字基础设施的建设。文章分析了加密资产相关的直接税与间接税问题，并对权益证明与最大可提取价值等较新议题进行了更深入的探讨。
