Mutual distributed ledgers (MDLs) have the potential to transform the way people and organizations handle identity, transaction and debt information. MDL technology provides an electronic public transaction record of integrity without central ownership. The ability to have a globally available, verifiable and untamperable source of data provides anyone wishing to provide trusted third-party services, i.e., most financial services firms, the ability to do so cheaply and robustly. Blockchain technology is a form of MDL. The InterChainZ project was a consortium research project to share learning on MDLs during the summer of 2015. The study found that InterChainZ showcased several distributed ledger configurations and numerous variants, exploring how they might work in a set of agreed “use cases.” The outputs were a series of functioning, interlinked MDLs along with software, explanatory materials and website information. The research consortium concluded that MDLs incorporating trusted third parties for some functions had significant potential in financial services, such as know-your-customer (KYC), anti- money laundering (AML), insurance, credit and wholesale financial services.

La versione italiana di questo documento è disponibile al seguente link: http://ssrn.com/abstract=2731132 The core technology of Bitcoin, the blockchain, has recently emerged as a disruptive innovation with a wide range of applications, potentially able to redesign our interactions in business, politics and society at large. Although scholarly interest in this subject is growing, a comprehensive analysis of blockchain applications from a political perspective is severely lacking to date. This paper aims to fill this gap and it discusses the key points of blockchain-based decentralized governance, which challenges to varying degrees the traditional mechanisms of State authority, citizenship and democracy. In particular, the paper verifies to which extent blockchain and decentralized platforms can be considered as hyper-political tools, capable to manage social interactions on large scale and dismiss traditional central authorities. The analysis highlights risks related to a dominant position of private powers in distributed ecosystems, which may lead to a general disempowerment of citizens and to the emergence of a stateless global society. While technological utopians urge the demise of any centralized institution, this paper advocates the role of the State as a necessary central point of coordination in society, showing that decentralization through algorithm-based consensus is an organizational theory, not a stand-alone political theory.

During 2013, the U.S. Treasury Department evoked the first use of the 2001 Patriot Act to exclude virtual currency provider Liberty Reserve from the U.S. financial system. This article will discuss: the regulation of virtual currencies; cybercrimes and payment systems; darknets, Tor and the “deep web;” Bitcoin; Liberty Reserve; Silk Road and Mt. Gox. Virtual currencies have quickly become a reality, gaining significant traction in a very short period of time, and are evolving rapidly. Virtual currencies present particularly difficult law enforcement challenges because of their: ability to transcend national borders in the fraction of a second; unique jurisdictional issues; and anonymity due to encryption. Due primarily to their anonymous characteristic, virtual currencies have been linked to numerous types of crimes, including facilitating marketplaces for: assassins; attacks on businesses; child exploitation (including pornography); corporate espionage; counterfeit currencies; drugs; fake IDs and passports; high yield investment schemes (Ponzi schemes and other financial frauds); sexual exploitation; stolen credit cards and credit card numbers; and weapons. Innovation in the pace of development of new currencies and technologies continue to create ongoing challenges for responsible users of technology and regulators alike. While technological advances create great opportunities to improve the health, living conditions, and general wellbeing of mankind; new technologies also create great challenges for nation states.

Purpose – The purpose of the article is to look closely at the phenomenon of the cryptocurrencies such as and bitcoin to identify their potential vulnerabilities to money laundering and financing of terrorism. It also explores their specific characteristics relevant to ML/FT risks. Design/methodology/approach – Using digicash and bitcoin protocols as primary cases for centralized and decentralized cryptocurrencies we analyse their characteristics against cash and cashless payments. We also draw on “bundle of attributes” that may define their attractiveness for common public or criminals. Findings – Our research shows that characteristics of the cryptocurrencies are unlikely to make them popular among the consumers, as demand for anonymity seems to be overrated. Cryptocurrencies can also be classified as payment instrument rather than private currencies; therefore their embededdness in the financial system minimizes the ML/FT risks. Research limitations/implications – Some decentralized cryptocurrencies operate within informal communities. Therefore, relations within these communities are constantly evolving and need to be monitored further. Practical implications – The paper provides an insight into the mechanics and classification of cryptocurrencies as payment instruments. Place of cryptocurrencies within the broader payment ecosystem defines their potential vulnerabilities to being abused by the criminals. Originality/value – The paper fills the gap in research on cryptocurrencies as payment instruments rather than private currencies and also provides an overview of their relevance for the Anti-money laundering and combating financing of terrorism (AML/CFT) regime.

Many cryptocurrencies have come into existence in recent years, with Bitcoin the most prominent among them. Although its short history has been volatile, the virtual currency maintains a core group of committed users. This paper presents an exploratory analysis of Bitcoin users. As a virtual currency and peer-to-peer payment system, Bitcoin may signal future challenges to state oversight and financial powers through its decentralized structure and offer of instantaneous transactions with relative anonymity. Very little is known about the users of Bitcoin, however. Utilizing publicly available survey data of Bitcoin users, this analysis explores the structure of the Bitcoin community in terms of wealth accumulation, optimism about the future of Bitcoin, and themes that attract users to the cryptocurrency. Results indicate that age, time of initial use, geographic location, mining status, engaging online discourse, and political orientation are all relevant factors that help explain various aspects of Bitcoin wealth, optimism, and attraction.

The new world of mobile devices offers reasonable likelihood that virtual currency will prevail on a global scale. Currently, the bitcoin crypto-currency model appears to be a forerunner. Bitcoin, a highly disruptive technology, has both supporters and detractors. Nonetheless, in concert with other trends, some form of virtual currency, even if a successor to bitcoin, appears to have a path forward. Virtual currencies will likely gain in stature as other novel, unspecified, and disruptive innovations take hold in a world of increasingly autonomous systems. This department is part of a special issue on mobile commerce.

The new, decentralized, anonymous digital currency Bitcoin has in less than three years gone from a proof-of-concept to being traded for about €78 million on a daily basis. Its ascendancy offers up a puzzle for financial regulators and other law-enforcers worldwide, while also promising to fulfill the political visions of a group of market-anarchist cryptographers. While it is still a very small economy in absolute terms, Bitcoin also poses some interesting challenges to traditional economic institutions, and is thus an interesting case for economic sociology. Using the notion of material embeddedness, this paper examines the possible implications of a further propagation of Bitcoin. If the currency proves a success, this will have ramifications for a large number of economic institutions, such as the possibility of taxation of untraceable money, the credit economy and interest rates, and international currency control.

Law enforcement efforts to combat money laundering are increasingly misplaced. As money laundering and other underlying crimes shift into cyberspace, U.S. law enforcement focuses on prosecuting financial institutions’ regulatory violations to prevent crime, rather than going after the criminals themselves. This Article will describe current U.S. anti-money laundering laws, with particular criticism of how attenuated prosecution has become from crime. The Article will then describe the use of Bitcoin as a money-laundering vehicle, and analyze the difficulties for law enforcement officials who attempt to choke off Bitcoin transactions in lieu of prosecuting underlying criminal activity. The Article concludes with recommendations that law enforcement should look to digital currency exchangers not as criminals, but instead as partners in the effort to eradicate money laundering and—more importantly—the crimes underlying the laundering.

Bitcoin offers a changing landscape on a global scale. It will be important, in future Bitcoin activity, for US law enforcement to carefully interact with foreign law enforcement and international regulatory policies. Bitcoin-related business fit nicely into Germany's existing regulations. Australia prohibits any kind of anonymous style digital currency product and has issued bank warnings. Canada offers room for Bitcoin business and does not yet see a need to license agents. While Bitcoin is popular in China, banks and businesses are now banned from trading BTC. The primary banking establishment in Thailand has issued a ban on Bitcoin.

First it captivated quintessential nerds; then political idealists who believed freedom had finally arrived. They projected their visions of revolution onto it. Predictably, the establishment rejected it. Research for this so-called revolution happened anonymously, born out of genuine curiosity rather than motivated by profit. Eventually, its usefulness became undeniable; industry and business paid attention. It became a revolution, as politicos had promised, but perhaps not the revolution they had in mind.

This note explores the origins and workings of Bitcoin, its popularity and regulation in Germany, how criminal enterprises have used Bitcoin, and governments’ ability to regulate it. To date, there have been no cases challenging the power of individuals to make transactions using Bitcoin. However, policymakers and consumers around the world are calling for enhanced government regulations. This leads to the question of whether national governments can regulate a currency that is not their own, and if so, what exactly those regulations should look like. This note will show that national governments around the world have no legal basis to prohibit Bitcoin users from entering the marketplace. National governments should refrain from passing legislation or regulations that would have a chilling effect on the use of Bitcoin. This note suggests that if a dispute arises, contract law provides a suitable solution for all consumers, and taxation provides sufficient regulation for governments. Section II of this note provides an overview of Bitcoin, its technological foundations, and its use in the marketplace. Section III analyzes Germany’s loose regulatory approach to regulating Bitcoin. Section IV examines how Bitcoin has been, or could be, utilized for illicit purposes by criminal enterprises around the world. Section V analyzes the arguments against increased regulation and proposes solutions that will not have a chilling effect on the adoption of Bitcoin.
