This book presents detailed case studies of the first commercial internet digital currency systems developed between 1996 and 2004. Transactions completed with the new technology circumvented all US financial regulations, an opening that transnational criminals exploited. Mullan explains how an entire industry of companies, agents, and participants turned a blind eye to crimes being committed in this unsupervised environment. He then tracks the subsequent changes made to US regulations that now prevent such unlicensed activity, illustrating the importance of supervising products and industries that arise from new disruptive technology. This book distills hundreds of hours of interviews with the creators and operators of early digital currency businesses to create detailed case studies of their practices.

This paper marks the launch of a new IMF series, Fintech Notes. Building on years of IMF staff work, it will explore pressing topics in the digital economy and be issued periodically. The series will carry work by IMF staff and will seek to provide insight into the intersection of technology and the global economy. The Rise of Digital Money analyses how technology companies are stepping up competition to large banks and credit card companies. Digital forms of money are increasingly in the wallets of consumers as well as in the minds of policymakers. Cash and bank deposits are battling with so-called e-money, electronically stored monetary value denominated in, and pegged to, a currency like the euro or the dollar. This paper identifies the benefits and risks and highlights regulatory issues that are likely to emerge with a broader adoption of stablecoins. The paper also highlights the risks associated with e-money: potential creation of new monopolies; threats to weaker currencies; concerns about consumer protection and financial stability; and the risk of fostering illegal activities, among others.

The fascinating untold story of digital cash and its creators—from experiments in the 1970s to the mania over Bitcoin and other cryptocurrencies Bitcoin may appear to be a revolutionary form of digital cash without precedent or prehistory. In fact, it is only the best-known recent experiment in a long line of similar efforts going back to the 1970s. But the story behind cryptocurrencies like Bitcoin and its blockchain technology has largely been untold—until now. In Digital Cash, Finn Brunton reveals how technological utopians and political radicals created experimental money to bring about their visions of the future: to protect privacy, bring down governments, prepare for apocalypse, or launch a civilization of innovation and abundance that would make its creators immortal. Filled with marvelous characters, stories, and ideas, Digital Cash is an engaging and accessible account of the strange origins and remarkable technologies behind today's cryptocurrency explosion.

New technologies are driving transformational changes in the global financial system. Virtual currencies (VCs) and the underlying distributed ledger systems are among these. VCs offer many potential benefits, but also considerable risks. VCs could raise efficiency and in the long run strengthen financial inclusion. At the same time, VCs could be potential vehicles for money laundering, terrorist financing, tax evasion and fraud. While risks to the conduct of monetary policy seem less likely to arise at this stage given the very small scale of VCs, risks to financial stability may eventually emerge as the new technologies become more widely used. National authorities have begun to address these challenges and will need to calibrate regulation in a manner that appropriately addresses the risks without stifling innovation. As experience is gained, international standards and best practices could be considered to provide guidance on the most appropriate regulatory responses in different fields, thereby promoting harmonization and cooperation across jurisdictions.

A cutting-edge look at how accelerating financial change, from the end of cash to the rise of cryptocurrencies, will transform economies for better and worse. We think weÕve seen financial innovation. We bank from laptops and buy coffee with the wave of a phone. But these are minor miracles compared with the dizzying experiments now underway around the globe, as businesses and governments alike embrace the possibilities of new financial technologies. As Eswar Prasad explains, the world of finance is at the threshold of major disruption that will affect corporations, bankers, states, and indeed all of us. The transformation of money will fundamentally rewrite how ordinary people live. Above all, Prasad foresees the end of physical cash. The driving force wonÕt be phones or credit cards but rather central banks, spurred by the emergence of cryptocurrencies to develop their own, more stable digital currencies. Meanwhile, cryptocurrencies themselves will evolve unpredictably as global corporations like Facebook and Amazon join the game. The changes will be accompanied by snowballing innovations that are reshaping finance and have already begun to revolutionize how we invest, trade, insure, and manage risk. Prasad shows how these and other changes will redefine the very concept of money, unbundling its traditional functions as a unit of account, medium of exchange, and store of value. The promise lies in greater efficiency and flexibility, increased sensitivity to the needs of diverse consumers, and improved market access for the unbanked. The risk is instability, lack of accountability, and erosion of privacy. A lucid, visionary work, The Future of Money shows how to maximize the best and guard against the worst of what is to come.

This book provides a comprehensive analysis of the cryptocurrency phenomenon from a financial/monetary point of view. It offers a unique slant in at least two ways, with the financial perspective as the reference point. An examination of the technicalities surrounding blockchain and the mining of cryptocurrencies is included, but the reading is oriented to those who seek to better understand how these technical issues help to explain the functioning and the potential of cryptocurrencies, without touching on coding aspects. Moreover, the book addresses cryptocurrencies as an evolution of the concept of money, and it frames the analysis to give readers all the knowledge needed to connect the cryptocurrency phenomenon with traditional monetary theories. In so doing, cryptocurrencies are not considered as a completely disconnected trend, set apart from traditional financial systems, but as innovations that will push the concept of money forward, without dismantling previous foundations. The book also includes a discussion on central banks, and stresses how their initial diffidence toward cryptocurrencies has turned into a more active approach that includes projects to develop the so-called Central Bank Digital Currencies (CBDC), thereby completing the analysis of the state of the art of the cryptocurrency surge. The mix of theoretical content on the concept of money, the description of payment tools and the functioning of the payment industry, and the analysis of blockchain and the cryptocurrency markets makes the book interesting reading for researchers, scholars and students of economics, finance, or business, enabling them to develop the ability to understand the dynamics of the cryptocurrency phenomenon and its possible evolution.
