Cryptocurrencies are frequently framed as future-oriented, technological innovations that decentralize money, thereby liberating it from centralized governance and the political tentacles of the state. This is misleading on several counts. First, electronic currencies cannot leave the politics of money behind even where they aim to disavow it. Instead, we can understand their impact as a political attempt to depoliticize money. Second, the dramatic price swings of cryptocurrencies challenge their self-fashioning as a new form of money and reveal them instead as speculative assets and securities in need of regulation. While the preferential tax and regulatory treatment of cryptocurrencies hinges on their nominal currency status, it is ironically precisely their success as speculative assets that has undermined these claims. Finally, far from heralding a radical break with the past, electronic currencies serve as a reminder of the unresolved global politics of money since the 1970s. To support these three interrelated theses this chapter places the rise of cryptocurrencies in the historical context of the international politics of money between the end of the Bretton Woods system and the response to the 2008 Financial Crisis.
加密货币经常被认为是面向未来的技术创新,可以分散资金,从而将其从集中治理和国家的政治触手中解放出来。这在几个方面具有误导性。首先,电子货币无法将货币政治抛在脑后,即使它们的目标是否认它。相反,我们可以把它们的影响理解为一种使金钱非政治化的政治尝试。其次,加密货币价格的剧烈波动挑战了它们作为一种新货币形式的自我塑造,并揭示了它们是需要监管的投机性资产和证券。虽然对加密货币的税收优惠和监管待遇取决于它们的名义货币地位,但具有讽刺意味的是,它们作为投机资产的成功恰恰削弱了这些说法。最后,电子货币远没有预示着与过去的彻底决裂,而是提醒人们,自上世纪70年代以来,全球货币政治一直悬而未决。为了支持这三个相互关联的论点,本章将加密货币的兴起置于布雷顿森林体系结束和对2008年金融危机的反应之间的国际货币政治的历史背景中。

This chapter addresses the myth of ‘decentralized governance’ of public blockchains, arguing that certain people who create, operate, or reshape them function much like fiduciaries of those who rely on these data structures. It compares the role of leading software developers and Frankel’s conception of a ‘fiduciary’ and finds much in common, as users place extreme trust in the developers to be both competent and loyal (i.e. to be free of conflicts of interest). The chapter frames the cost–benefit analysis necessary to evaluate whether it is wise to treat these parties as fiduciaries, and outlines key questions needed to flesh out the fiduciary categorization. For example, which software developers are influential enough to resemble fiduciaries? Are all users of a blockchain ‘entrustors’ of the fiduciaries who operate the blockchain, or only a subset of those who rely on the blockchain? The chapter concludes by considering the broader implications of treating software developers as fiduciaries, given the existing accountability paradigm that largely shields them from liability for the code they create.
本章解决了公共区块链“去中心化治理”的神话,认为某些创建、运营或重塑公共区块链的人的功能很像那些依赖这些数据结构的人的受托人。它比较了领先的软件开发人员的角色和Frankel的“受托人”概念,并发现了许多共同点,因为用户极度信任开发人员,认为他们既能干又忠诚(即没有利益冲突)。本章构建了必要的成本效益分析,以评估将这些当事人视为受托人是否明智,并概述了充实受托人分类所需的关键问题。例如,哪些软件开发人员的影响力足以与受托人相似?区块链的所有用户都是运营区块链的受托人的“委托人”,还是只是依赖区块链的一部分人?本章最后考虑了将软件开发人员视为受托人的更广泛的含义,因为现有的责任范式在很大程度上保护了他们免受他们创建的代码的责任。

Monetary Policy in the Digital Age 数字时代的货币政策
Pub Date : 2019-06-10 DOI: 10.1093/OSO/9780198842187.003.0006
Claus D. Zimmermann
The potential of digital money to replace state-issued fiat money as the predominant means of payment for retail goods combined with its ability to flow freely across international borders is increasingly attracting attention among central bankers, the media, and scholars. The concern is that central banks could lose control over the monetary aggregates regulating the money supply for conducting monetary policy. This chapter examines important regulatory challenges that arise from the increasing use of virtual currency systems. Stable monetary regimes are expected to provide a level of resilience against three types of monetary stability risks: (i) structural ‘deflation’; (ii) lacking flexibility to respond to temporary shocks to money demand; and (iii) failing to fulfil the traditional key function of lender of last resort. It is against these three types of risks that the sustainability of virtual currency systems can be assessed. The chapter concludes that, as they attract increasing attention and account for increasing volumes of financial flows, virtual currency schemes may ultimately have to become subject to increasingly tight regulation on a global level.
数字货币取代国家发行的法定货币成为零售商品主要支付手段的潜力,以及其跨境自由流动的能力,正日益引起央行官员、媒体和学者的关注。令人担忧的是,央行可能会失去对货币总量的控制,而货币总量是为实施货币政策而调节货币供应的。本章探讨了越来越多地使用虚拟货币系统所带来的重要监管挑战。稳定的货币制度有望提供一定程度的弹性,以应对三种类型的货币稳定风险:(1)结构性“通缩”;(ii)缺乏应对货币需求暂时冲击的灵活性;(三)未能履行最后贷款人的传统关键职能。正是针对这三种风险,才能评估虚拟货币系统的可持续性。这一章的结论是,随着它们吸引越来越多的关注,并导致越来越多的资金流动,虚拟货币计划最终可能不得不在全球范围内受到越来越严格的监管。

Distributed ledger technology, a variant of which is blockchain technology, represents one of the most important innovations of the FinTech revolution. Academics, policy-makers, and market participants are experimenting with the technology with the aim of enhancing the functioning of financial markets. Industry consortia are being formed by the biggest financial institutions in the world seeking to leverage the use of the technology, in order to improve the clearing and settlement process. Furthermore, central banks in advanced and developing economies are examining the potential of using the technology in market infrastructures operated by central banks and are even exploring the possibility of issuing digital base money. Nevertheless, the widespread adoption of distributed ledger technology as envisioned by its ardent supporters encounters considerable legal obstacles, including the numerous new regulations imposed on financial markets and market participants in the aftermath of the Global Financial Crisis. This chapter seeks to disentangle the myths from the realities of the so-called distributed ledger technology or blockchain revolution and discusses how the legal regime can act both as an impediment and a catalyst to the widespread adoption of the technology.
分布式账本技术是区块链技术的一种变体,代表了金融科技革命中最重要的创新之一。学者、政策制定者和市场参与者正在试验这项技术,目的是增强金融市场的功能。世界上最大的金融机构正在组建行业联盟,寻求利用区块链技术来改善清算和结算流程。此外,发达经济体和发展中经济体的央行正在研究在央行运营的市场基础设施中使用该技术的潜力,甚至在探索发行数字基础货币的可能性。然而,热心支持者所设想的分布式账本技术的广泛采用遇到了相当大的法律障碍,包括在全球金融危机之后对金融市场和市场参与者施加的众多新法规。本章试图从所谓的分布式账本技术或区块链革命的现实中解开神话,并讨论法律制度如何成为广泛采用该技术的障碍和催化剂。

This introductory chapter provides an overview of the main legal and policy implications of blockchain technology. It proceeds in four steps. First, the chapter traces the technical and legal evolution of blockchain applications since the early days of Bitcoin, highlighting in particular the political ambitions and tensions that have marked many of these projects from the start. Second, it shows how blockchain applications have created new calculative spaces of financial markets that seek to challenge existing forms of money. Third, it discusses the core points of friction with incumbent legal systems, with a particular focus on the regulability of decentralized systems in general and data protection concerns in particular. Fourth, the chapter provides an outline to the contributions to the volume, which span a wide array of topics at the intersection of blockchain, law, and politics.

Regulating the Shadow Payment System 规范影子支付体系
Pub Date : 2019-06-10 DOI: 10.1093/OSO/9780198842187.003.0010
J. Greenacre
Recent years has seen the growth of the ‘shadow payment system’. This system includes Bitcoin exchanges, PayPal, Alipay in China, and mobile money services in Africa. On current projections, this global ‘shadow payment system’ will perform an ever-greater portion of payments in most economies in the world. This chapter explores what legal tools can be used to protect users’ funds stored within the shadow payment system. It provides a framework for identifying risks to users’ funds, the range of relevant legal tools and their effectiveness, and uses this framework to make three claims. First, insolvency of an actor in the shadow payment system exposes users’ funds to two risks. One is loss of value, which means the potential write-down of funds when users are characterized as unsecured creditors. The other is illiquidity, meaning users face a delay in converting or transferring funds during bankruptcy proceedings. Second, there is little information about legal tools currently used in the shadow payment system and their effectiveness. There is also little guidance on the desirability of using ex post tools, such as deposit insurance and lender of last resort, to protect users’ funds. This is because the policy community is yet to identify the benefits and costs of different roles for the shadow payment system in an economy. Is it an investment asset, alternative retail funds transfer system, vital payment infrastructure on which the economy relies, or something else? Third, mobile money can provide insights into discussions about using legal tools to protect users’ funds. This is because over the past ten years, this shadow payment system has become subject to increasingly sophisticated legal and regulatory regimes. A key insight from mobile money is ex ante and ex post tools appear required to address loss of value and illiquidity risks. A similar package of reforms may be needed to build strong, stable shadow payment systems in Japan, the United States, and other developed countries. The chapter uses mobile money in Malawi as a case study for developing this point.
近年来,“影子支付系统”得到了发展。该系统包括中国的比特币交易、PayPal、支付宝,以及非洲的移动支付服务。根据目前的预测,这种全球“影子支付系统”将在世界上大多数经济体中发挥越来越大的作用。本章探讨了可以使用哪些法律工具来保护存储在影子支付系统中的用户资金。它提供了一个框架,用于识别用户资金的风险、相关法律工具的范围及其有效性,并利用该框架提出了三个主张。首先,影子支付系统中一个参与者的破产使用户的资金面临两种风险。一个是价值损失,这意味着当用户被描述为无担保债权人时,可能会冲销资金。另一个是流动性不足,这意味着在破产程序期间,用户在转换或转移资金方面面临延迟。其次,关于影子支付系统目前使用的法律工具及其有效性的信息很少。对于使用事后工具(如存款保险和最后贷款人)来保护用户资金的可取性,也几乎没有指导意见。这是因为政策界尚未确定影子支付系统在经济中扮演不同角色的收益和成本。它是一种投资资产、另类零售资金转移系统、经济所依赖的重要支付基础设施,还是别的什么?第三,移动货币可以为使用法律工具保护用户资金的讨论提供见解。这是因为在过去十年中,这种影子支付系统受到了越来越复杂的法律和监管制度的制约。移动货币的一个关键观点是,似乎需要事前和事后工具来解决价值损失和非流动性风险。为了在日本、美国和其他发达国家建立强大、稳定的影子支付系统,可能需要类似的一揽子改革。本章使用马拉维的移动货币作为发展这一点的案例研究。

Conflicts of Laws and Codes 法律和法规的冲突
Pub Date : 2019-06-10 DOI: 10.1093/oso/9780198842187.003.0016
Florian Möslein
Blockchain technology promises to perform tasks that have traditionally been assigned to the law and the realm of legal institutions. Smart contracts create agreements that are both automatable by computers and enforceable via the tamper-proof execution of computer codes. Based on such smart contracts, some providers of blockchain technologies offer ‘to act as a digital jurisdiction’. The promise seems to be that law of the relevant jurisdiction is entirely substituted by the rules codified in the blockchain. However, even if it has often been argued that the ‘Code Is Law’, the law is not—and arguably never will be—entirely redundant. Therefore, the challenge is to identify the boundaries of such digital jurisdictions by clarifying the relationship between law and code and to develop new principles for conflicts of laws or rather principles for the conflict of laws and codes.
区块链技术有望执行传统上分配给法律和法律机构领域的任务。智能合约创建的协议既可以由计算机自动执行,又可以通过计算机代码的防篡改执行来强制执行。基于这种智能合约,一些区块链技术提供商提供“充当数字司法管辖区”。其承诺似乎是,相关司法管辖区的法律完全被区块链中编纂的规则所取代。然而,即使人们经常争论“法典就是法律”,法律并不是——也永远不会是完全多余的。因此,挑战在于通过澄清法律和法典之间的关系来确定这些数字司法管辖区的边界,并制定法律冲突的新原则,或者更确切地说,是法律和法典冲突的原则。

Corporate Governance for Complex Cryptocurrencies? 复杂加密货币的公司治理?
Pub Date : 2019-06-10 DOI: 10.1093/oso/9780198842187.003.0008
Philip Hacker
Cryptocurrencies such as Bitcoin or Ethereum are gaining ground not only as alternative modes of payment but also as platforms for financial innovation, particularly through token sales or initial coin offerings (‘ICOs’). All of these ventures are based on decentralized, permissionless blockchain technology, distinguished by their openness to, and the formal equality of, participants. However, recent cryptocurrency crises have shown that these architectures lack robust governance frameworks and are therefore prone to patterns of re-centralization. They are informally dominated by coalitions of powerful players within the cryptocurrency ecosystem who may violate basic rules of the blockchain community without accountability or sanction. This chapter first suggests that cryptocurrency and token-based ecosystems can be fruitfully analysed as complex systems that have been studied for decades in complexity theory and have recently gained prominence in financial regulation, too. It applies these insights to three key case studies: the Bitcoin Hard Fork of 2013; the Ethereum hard fork of 2016, following the DAO hack; and the ongoing Bitcoin scaling debate. Second, the chapter argues that complexity-induced uncertainty can be reduced, and elements of stability and order strengthened, by adapting a corporate governance framework to blockchain-based organizations: cryptocurrencies, and decentralized applications built on top of them via token sales. The resulting ‘comply-or-explain’ approach combines transparency and accountability with the necessary flexibility that allows blockchain developers to continue to experiment for the sake of innovation. Eventually, however, the coordination of these activities may necessitate the establishment of a self-regulatory institution.
比特币或以太坊等加密货币不仅作为替代支付方式,而且作为金融创新的平台,特别是通过代币销售或首次代币发行(ICOs),正在取得进展。所有这些企业都基于去中心化、无需许可的区块链技术,其特点是对参与者的开放性和形式上的平等。然而,最近的加密货币危机表明,这些架构缺乏强大的治理框架,因此容易出现重新集中的模式。它们非正式地由加密货币生态系统中强大的参与者联盟主导,这些参与者可能违反区块链社区的基本规则而不受问责或制裁。本章首先表明,加密货币和基于代币的生态系统可以作为复杂系统进行富有成效的分析,这些系统在复杂性理论中已经研究了几十年,最近在金融监管中也获得了突出地位。它将这些见解应用于三个关键案例研究:2013年的比特币硬分叉;2016年的以太坊硬分叉,紧随DAO黑客事件;以及正在进行的比特币扩容辩论。其次,本章认为,通过将公司治理框架适用于基于区块链的组织:加密货币,以及通过代币销售建立在其之上的去中心化应用程序,可以减少复杂性引起的不确定性,并加强稳定和秩序的要素。由此产生的“服从或解释”方法将透明度和问责制与必要的灵活性相结合,使区块链开发人员能够为了创新而继续进行实验。然而,这些活动的协调最终可能需要建立一个自我管理的机构。

All of these ventures are based on decentralized, permissionless blockchain technology, distinguished by their openness to, and the formal equality of, participants. However, recent cryptocurrency crises have shown that these architectures lack robust governance frameworks and are therefore prone to patterns of re-centralization. They are informally dominated by coalitions of powerful players within the cryptocurrency ecosystem who may violate basic rules of the blockchain community without accountability or sanction. This chapter first suggests that cryptocurrency and token-based ecosystems can be fruitfully analysed as complex systems that have been studied for decades in complexity theory and have recently gained prominence in financial regulation, too. It applies these insights to three key case studies: the Bitcoin Hard Fork of 2013; the Ethereum hard fork of 2016, following the DAO hack; and the ongoing Bitcoin scaling debate. Second, the chapter argues that complexity-induced uncertainty can be reduced, and elements of stability and order strengthened, by adapting a corporate governance framework to blockchain-based organizations: cryptocurrencies, and decentralized applications built on top of them via token sales. The resulting ‘comply-or-explain’ approach combines transparency and accountability with the necessary flexibility that allows blockchain developers to continue to experiment for the sake of innovation. Eventually, however, the coordination of these activities may necessitate the establishment of a self-regulatory institution.","PeriodicalId":205528,"journal":{"name":"Regulating Blockchain","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126059674","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Banking in a Digital Fiat Currency Regime 数字法币制度下的银行业务

This chapter explores the future of banking in a digital fiat currency (‘DFC’) regime, defined as a monetary regime in which retail and wholesale consumers have direct access to public digital checking and payments services, independent of the existing bank-centric depository system. I argue that in such a regime, existing banks will continue to perform the valuable social function of underwriting loans and evaluating collateral, even as their checking and payments processing functions will be rendered obsolete. Such a system would improve payments system resiliency, while addressing the safe asset shortage issues associated with insurance caps on bank deposit accounts. At the same time, a DFC regime would necessarily clarify the public nature of the existing credit system, wherein commercial banks are (inherently) entrusted to underwrite loans and subjectively evaluate collateral. Thus, digital fiat currency technology represents more than a mere improvement in payment system efficiency—it has the potential to transform the banking industry, simplify financial regulation, and recast our collective understanding of how money and banking work in the modern economy.
本章探讨了数字法定货币(“DFC”)制度下银行业的未来,该制度被定义为一种货币制度,在这种货币制度下,零售和批发消费者可以直接获得公共数字支票和支付服务,独立于现有的以银行为中心的存款系统。我认为,在这样一种制度下,现有银行将继续履行承销贷款和评估抵押品的有价值的社会职能,即使它们的支票和支付处理职能将被淘汰。这样的系统将提高支付系统的弹性,同时解决与银行存款账户保险上限相关的安全资产短缺问题。与此同时,DFC制度必然会澄清现有信贷体系的公共性质,其中商业银行(本质上)被委托承销贷款并主观评估抵押品。因此,数字法定货币技术代表的不仅仅是支付系统效率的提高——它有可能改变银行业,简化金融监管,并重塑我们对现代经济中货币和银行运作方式的集体理解。

Regulation of Blockchain Token Sales in the United States 美国区块链代币销售监管

This chapter provides an overview of how US securities regulation applies to the sale of cryptographic tokens using a distributed ledger, so-called initial coin offerings. Token sale transactions that meet the definition of ‘investment contract’ qualify as regulated securities transactions following the seminal 1946 court decision in the Securities Exchange Commission’s lawsuit against the W. J. Howey company. Currently, there exists substantial legal uncertainty regarding the regulatory classification of token sales involving utility tokens that provide their holders with non-financial, software-based functionality. As implied in a June 2018 speech by a high-ranking SEC official, sales of tokens may initially qualify as regulated securities transactions, yet later fail to qualify as regulated investment contracts if the tokens’ underlying network becomes sufficiently decentralized. Distributed ledger technology is disrupting the nature and operation of early-stage fundraising and access to software services and enabling the sale of digital tokens that operate as a cryptocurrency or provide access to a software service through the use of a blockchain or distributed ledger. The sale of such tokens, so-called initial coin offerings (‘ICOs’), is often in exchange for cryptocurrencies, such as Ethereum or Bitcoin (however, tokens could be sold in exchange for fiat currency). From January to May 2018, globally US$13.7 billion in tokens were sold by 537 companies or projects, an amount greater than all previous time periods combined. This chapter discusses under what circumstances US securities law applies to the sale of such tokens.
本章概述了美国证券监管如何适用于使用分布式账本(即所谓的首次代币发行)销售加密代币。符合“投资合同”定义的代币销售交易符合1946年证券交易委员会对W. J. Howey公司诉讼的开创性法院判决后的受监管证券交易资格。目前,关于代币销售的监管分类存在很大的法律不确定性,这些代币涉及为其持有人提供非金融、基于软件的功能的实用代币。正如美国证券交易委员会一位高级官员在2018年6月的讲话中所暗示的那样,代币的销售最初可能符合受监管的证券交易资格,但如果代币的底层网络变得足够分散,那么后来就不符合受监管的投资合同资格。分布式账本技术正在扰乱早期筹款和获取软件服务的性质和运作,并允许销售作为加密货币运行的数字代币,或通过使用区块链或分布式账本提供对软件服务的访问。此类代币的销售,即所谓的首次代币发行(ICOs),通常是为了换取加密货币,如以太坊或比特币(然而,代币可以出售以换取法定货币)。从2018年1月到5月,全球537家公司或项目销售了137亿美元的代币,超过了之前所有时期的总和。本章讨论在何种情况下美国证券法适用于此类代币的销售。
