Enforcement Trends in Cryptocurrency
Latham & Watkins Financial Institutions Group & White Collar December 9, 2015 | Number 1904 Defense & Investigations Practice Enforcement Trends in Cryptocurrency Cryptocurrency is on the rise...and so are enforcement actions. In less than a decade, cyptocurrencies have grown from a novelty reserved for those dealing in the illicit into a robust platform embraced by financial institutions and businesses alike. Wall Street and strategic investors have increasingly taken note, working to adapt their technology, streamline market trading and integrate cryptocurrency into everyday financial transactions. The rapid adoption of cryptocurrencies has also led to increased government enforcement activity. These actions evidence US regulators’ appetite to investigate fraud and other violations linked to cryptocurrency — often using traditional laws and regulations. Given this increased government scrutiny, financial institutions and traders should understand how regulators have policed the virtual world in the past in order to be prepared for the future. Government Enforcement Actions in the Cryptocurrency Space Unsurprisingly, government regulators, including the Securities and Exchange Commission (SEC), the Department of Justice (DOJ), the Commodities Futures Trading Commission (CFTC), the Federal Trade Commission (FTC) and the Financial Crimes Enforcement Network (FinCEN), have become increasingly active in policing the cryptocurrency space. The below enforcement actions provide a bird’s-eye view of how the enforcement framework for cryptocurrencies -

Creation and Resilience of Decentralized Brands: Bitcoin & the Blockchain Syeda Mariam Humayun A dissertation submitted to the Faculty of Graduate Studies in partial fulfillment of the requirements for the degree of Doctor of Philosophy Graduate Program in Administration Schulich School of Business York University Toronto, Ontario March 2019 © Syeda Mariam Humayun 2019 Abstract: This dissertation is based on a longitudinal ethnographic and netnographic study of the Bitcoin and broader Blockchain community. The data is drawn from 38 in-depth interviews and 200+ informal interviews, plus archival news media sources, netnography, and participant observation conducted in multiple cities: Toronto, Amsterdam, Berlin, Miami, New York, Prague, San Francisco, Cancun, Boston/Cambridge, and Tokyo. Participation at Bitcoin/Blockchain conferences included: Consensus Conference New York, North American Bitcoin Conference, Satoshi Roundtable Cancun, MIT Business of Blockchain, and Scaling Bitcoin Tokyo. The research fieldwork was conducted between 2014-2018. The dissertation is structured as three papers: - “Satoshi is Dead. Long Live Satoshi.” The Curious Case of Bitcoin: This paper focuses on the myth of anonymity and how by remaining anonymous, Satoshi Nakamoto, was able to leave his creation open to widespread adoption. - Tracing the United Nodes of Bitcoin: This paper examines the intersection of religiosity, technology, and money in the Bitcoin community. - Our Brand Is Crisis: Creation and Resilience of Decentralized Brands – Bitcoin & the Blockchain: Drawing on ecological resilience framework as a conceptual metaphor this paper maps how various stabilizing and destabilizing forces in the Bitcoin ecosystem helped in the evolution of a decentralized brand and promulgated more mainstreaming of the Bitcoin brand. ii Dedication: To my younger brother, Umer. -
A Solution Towards Eliminating Transaction Malleability in Bitcoin
J Inf Process Syst, Vol.14, No.4, pp.837~850, August 2018 ISSN 1976-913X (Print) https://doi.org/10.3745/JIPS.03.0101 ISSN 2092-805X (Electronic) A Solution towards Eliminating Transaction Malleability in Bitcoin Ubaidullah Rajput*, Fizza Abbas*, and Heekuck Oh** Abstract Bitcoin is a decentralized crypto-currency, which is based on the peer-to-peer network, and was introduced by Satoshi Nakamoto in 2008. Bitcoin transactions are written by using a scripting language. The hash value of a transaction’s script is used to identify the transaction over the network. In February 2014, a Bitcoin exchange company, Mt. Gox, claimed that they had lost hundreds of millions US dollars worth of Bitcoins in an attack known as transaction malleability. Although known about since 2011, this was the first known attack that resulted in a company loosing multi-millions of US dollars in Bitcoins. Our reason for writing this paper is to understand Bitcoin transaction malleability and to propose an efficient solution. Our solution is a softfork (i.e., it can be gradually implemented). Towards the end of the paper we present a detailed analysis of our scheme with respect to various transaction malleability-based attack scenarios to show that our simple solution can prevent future incidents involving transaction malleability from occurring. We compare our scheme with existing approaches and present an analysis regarding the computational cost and storage requirements of our proposed solution, which shows the feasibility of our proposed scheme. Keywords Crypto-currency, Bitcoin, Transaction Malleability 1. Introduction After its introduction in 2008 by Satoshi Nakamoto, the Bitcoin crypto-currency has gained significant popularity amongst other various crypto-currencies. -

Bitcoin and Money Laundering: Mining for an Effective Solution * DANTON BRYANS INTRODUCTION Technology forges ahead at a rapid pace, whether we like it or not. Criminals recognize this inevitability and use technological improvements to advance their craft,1 committing crimes from half a world away in real time. Meticulous criminals also use technological advancements to distance themselves from their illegal activities and profits through use of virtual banking and electronic money transfer systems, which allow criminals to buy, sell, and exchange goods without any physical interaction. Though such services use digital logs that serve to identify a sender and a receiver’s digital identities, criminals possess the means to obfuscate their digital identity by simply spoofing their Internet Protocol address or by using another individual’s account, essentially making their activities untraceable. -
A Bitcoin Governance Network: the Multi-Stakeholder Solution to the Challenges of Cryptocurrency
A BITCOIN GOVERNANCE NETWORK: The Multi-stakeholder Solution to the Challenges of Cryptocurrency Alex Tapscott Director, Institutional Equity Sales Canaccord Genuity Cryptocurrencies are products of the digital revolution and the networked age. As distributed networks with no central issuer and no central command, they are also a distinctly global phenomenon that will force national governments to not only re-evaluate a number of substantive regulatory issues but perhaps also re-think the very nature of governance itself. Cryptocurrencies are wresting control over many issues from traditional decision-makers. Multi-stakeholder governance, founded on principles of transparency and inclusiveness and legitimized by consensus, is the 21st century solution. When leaders of the old paradigm adapt and collaborate more closely with private enterprise, civil society organizations and other stakeholders in the network, then bitcoin and other cryptocurrency technologies can fulfill their potential and gain widespread adoption. © Global Solution Networks 2014 A Bitcoin Governance Network: The Multi-stakeholder Solution to the Challenges of Cryptocurrency i Table of Contents Idea in Brief 1 The Challenge for Governments 2 How Cryptocurrencies Work 4 Bitcoin Volatility and Price 5 Opportunities and Challenges 6 Opportunities 6 Challenges 11 A Bitcoin Governance Network 13 GSN Types for a Bitcoin Governance Network 16 Standards Networks 16 Policy Networks 18 Knowledge Networks 19 Watchdog Networks 20 The GSN Approach: Core Principles, Conclusions and -
Cryptocurrency and the Blockchain: Technical Overview and Potential Impact on Commercial Child Sexual Exploitation
Cryptocurrency and the BlockChain: Technical Overview and Potential Impact on Commercial Child Sexual Exploitation Prepared for the Financial Coalition Against Child Pornography (FCACP) and the International Centre for Missing & Exploited Children (ICMEC) by Eric Olson and Jonathan Tomek, May 2017 Foreword The International Centre for Missing & Exploited Children (ICMEC) advocates, trains and collaborates to eradicate child abduction, sexual abuse and exploitation around the globe. Collaboration – one of the pillars of our work – is uniquely demonstrated by the Financial Coalition Against Child Pornography (FCACP), which was launched in 2006 by ICMEC and the National Center for Missing & Exploited Children. The FCACP was created when it became evident that people were using their credit cards to buy images of children being sexually abused online. Working alongside law enforcement, the FCACP followed the money to disrupt the economics of the child pornography business, resulting in the virtual elimination of the use of credit cards in the United States for the purchase of child sexual abuse content online. And while that is a stunning accomplishment, ICMEC and the FCACP are mindful of the need to stay vigilant and continue to fight those who seek to profit from the sexual exploitation of children. It is with this in mind that we sought to research cryptocurrencies and the role they play in commercial sexual exploitation of children. This paper examines several cryptocurrencies, including Bitcoin, and the Blockchain architecture that supports them. It provides a summary of the underground and illicit uses of the currencies, as well as the ramifications for law enforcement and industry. ICMEC is extremely grateful to the authors of this paper – Eric Olson and Jonathan Tomek of LookingGlass Cyber Solutions. -

While there are many easily reglated intermediaries when it comes to traditional securities and derivatives, emerging bitcoin- denominated instruments rely much less on traditional intermediaries such as banks and securities exchanges. Additionally, the block chain technology that Bitcoin introducedfor thefirst time makes completely decentralized markets and exchanges possible, thus eliminating the need for intermediaries in complex financial transactions. In this Article we surey the type of financial instruments and transactions that will most likely be of interest to regulators, including traditional securities and derivatives, new bitcoin-denominatedinstruments, and completely decentralized markets and exchanges. -

Bitcoin and the Uniform Commercial Code Jeanne L. Schroeder* Much of the discussion of bitcoin in the popular press has concentrated on its status as a currency. Putting aside a vocal minority of radical libertarians and anarchists, however, many bitcoin enthusiasts are concentrating on how its underlying technology – the blockchain – can be put to use for wide variety of uses. For example, economists at the Fed and other central banks have suggested that they should encourage the evolution of bitcoin’s blockchain protocol which might allow financial transactions to clear much efficiently than under our current systems. As such, it also holds out the possibility of becoming that holy grail of commerce – a payment system that would eliminate or minimize the roles of third party intermediaries. In addition, the NASDAQ and a number of issuers are experimenting with using the blockchain to record the issuing and trading of investments securities. -
Bitcoin Governance As a Decentralized Financial Market Infrastructure
Bitcoin Governance as a Decentralized Financial Market Infrastructure Hossein Nabilou Abstract Bitcoin is the oldest and most widely established cryptocurrency network with the highest market capitalization among all cryptocurrencies. Although bitcoin (with lowercase b) is increasingly viewed as a digital asset belonging to a new asset class, the Bitcoin network (with uppercase B) is a decentralized financial market infrastructure (dFMI) that clears and settles transactions in its native asset without relying on the conventional financial market infrastructures (FMIs). To be a reliable asset class as well as a dFMI, however, Bitcoin needs to have robust governance arrangements; whether such arrangements are built into the protocol (i.e., on-chain governance mechanisms) or relegated to the participants in the Bitcoin network (i.e., off-chain governance mechanisms), or are composed of a combination of both mechanisms (i.e., a hybrid form of governance). This paper studies Bitcoin governance with a focus on its alleged shortcomings. In so doing, after defining Bitcoin governance and its objectives, the paper puts forward an idiosyncratic governance model whose main objective is to preserve and maximize the main value proposition of Bitcoin, i.e., its censorship- resistant property, which allows participants to transact in an environment with minimum social trust. Therefore, Bitcoin governance, including the processes through which Bitcoin governance crises have been resolved and the standards against which the Bitcoin Improvement Proposals (BIPs) are examined, should be analyzed in light of the prevailing narrative of Bitcoin as a censorship-resistant store of value and payment infrastructure. Within such a special governance model, this paper seeks to identify the potential shortcomings in Bitcoin governance by reference to the major governance crises that posed serious threats to Bitcoin in the last decade.
