1 Daniela Dekhtyar Role of the State Attorney General Daniela Dekhtyar Role of the State Attorney General – Seminar Paper Role of the State Attorney General in the Oversight of Bitcoin As 2015 comes to a close, positive reviews of Bitcoin are on the rise. Numerous financial press outlets praised Bitcoin’s year, noting that Bitcoin was the world’s best performing “currency”1 in 2015.2 Furthermore, many financial industry experts report that even traditional banks are looking to incorporate the technology behind Bitcoin into their banking practices.3 Though Bitcoin’s short existence has thus far consisted of multiple upswings and downswings, recent funding announcements in Bitcoin-related ventures have given it renewed legitimacy, suggesting that this most recent upswing may have staying power.4 1 Though many refer to Bitcoin as a currency, such terminology is not entirely accurate. See infra note 5 and accompanying text. 2 See Mark Gilbert, Bitoinc Won 2015. Apple . Did Not, Bloomberg (Dec. 29, 2015), http://www.bloombergview.com/articles/2015-12-29/bitcoin-won-in-2015-but-apple-lost-big (calling Bitcoin the “comeback of the year”); Eric Rosenbaum, Bitcoin’s Back: Big Year for Controversial Digital Currency, CNBC (Dec. 28, 2015), http://www.cnbc.com/2015/12/28/only- one-global-currency-trounced-the-dollar-this-year.html [hereinafter, Rosenbaum, Bitcoin’s Back] (“[T]o find what’s arguably been the best global currency in 2015, an investor might need to put quote marks around the term ‘global currency.’”). 3 See Prableen Bajpai, 2015: A Blockbuster Year for Bitcoin’s Blockchain Technology, Nasdaq (Dec. 30, 2015), http://www.nasdaq.com/article/2015-a-blockbuster-year-for-bitcoins- blockchain-technology-cm559938 (reporting Bitcoin’s blockchain technology “has received an overwhelming response from a group, which doesn’t stand bitcoin one bit but is sure in love with blockchain.

In the United States, federal financial regulators have taken the most significant moves toward regulation, but certain state agencies are jumping in, as well. Undoubtedly, the question on every government agency’s mind (even those that have already addressed Bitcoin in some way) is, “How exactly do I fit in?” This paper argues that there is a role for state Attorneys General (AGs) to play in the oversight of Bitcoin and similar virtual currencies, particularly in the realm of consumer protection. This paper proceeds in four parts. Part I provides an overview of Bitcoin, explaining its goals and how it works. Part II describes Bitcoin’s advantages and risks, highlighting why regulation is necessary. Part III discusses the various approaches that federal government agencies have taken in regulating Bitcoin and explores the potential role for state AGs. Part IV concludes. I. What is Bitcoin? Bitcoin is a decentralized digital peer-to-peer network that allows for the creation and exchange of bitcoins.5 In plain English, Bitcoin is an online payment platform.6 According to its creator, Satoshi Nakamoto,7 the primary purpose of Bitcoin was to establish a means of 5 Bitcoin is colloquially referred to as a currency, but legally its definition as a currency is widely debated. For a discussion of Bitcoin’s classification as a currency, commodity, or investment contract, see Nicholas Godlove, Regulatory Overview of Virtual Currency, 10 Okla. J. L. & Tech. 71 [hereinafter Godlove, Regulatory Overview of Virtual Currency] (2014). 6 See Daniela Sonderegger, A Regulatory and Economic Perplexity: Bitcoin Needs Just a Bit of Regulation, 47 Wash. U. J.L. & Pol’y 175, 181 [hereinafter Sonderegger, Bitcoin Needs Just a Bit of Regulation] (“Bitcoin, at its core, is . a payment system or platform through which payments can be made.”); see also Robert McMillan and Cade Metz, Bitcoin Survival Guide: Everything You Need to Know About the Future of Money, Wired (Nov. 25, 2013), http://www.wired.com/2013/11/bitcoin-survival-guide/ [hereinafter McMillan & Metz, Bitcoin Survival Guide] (stating Bitcoin “operates as an extremely low-cost money-moving platform.”). 7 Satoshi Nakamoto is the pseudonym of an anonymous programmer or group of programmers who released the software for Bitcoin onto the internet in 2009. See McMillan & Metz, Bitcoin 2 Daniela Dekhtyar – Seminar Paper processing electronic payments independently of financial institutions.8 Nakamoto argued that the dominant mode of online financial transactions today increasingly relies on financial institutions to act as intermediaries between senders and beneficiaries of payments and that such reliance has numerous disadvantages.9 First, requiring a single third party (the financial institution) to mediate disputed transactions yields transaction costs; the greater the number of transactions, the greater the number of disputes, and the longer it takes for a single party to resolve those disputes.10 Second, reliance on financial institutions places a practical limit on transaction size; because intermediaries charge fees for processing transactions, it becomes impractical for sellers to provide a low-value product online unless a certain minimum volume of Survival Guide, supra note 6 (“About five years ago, using the pseudonym Satoshi Nakamoto, an anonymous computer programmer or group of programmers built the Bitcoin software system and released it onto the internet.”). While the true identity of this programmer(s) remained unknown for years, less than one month ago, numerous tech media outlets reported that Nakamoto’s true identity was likely discovered; Nakamoto is actually a pseudonym for an Australian businessman, Craig Steven Wright, and a deceased U.S. forensic researcher, Dave Kleiman. See Sam Bidde and Andy Crush, This Australian Says He and His Dead Friend Invented Bitcoin, Gizmodo (Dec. 8, 2015) http://gizmodo.com/this-australian-says-he-and-his- dead-friend-invented-bi-1746958692 (“According to a cache of documents provided to Gizmodo which were corroborated in interviews, Craig Steven Wright, an Australian businessman based in Sydney, and Dave Kleiman, an American computer forensics expert who died in 2013, were involved in the development of the digital currency.); Andy Greenberg and Gwen Branwen, Bitcoin’s Creator Satoshi Nakamoto is Probably This Unknown Australian Genius, Wired (Dec. 8, 2015), http://www.wired.com/2015/12/bitcoins-creator-satoshi-nakamoto-is-probably-this- unknown-australian-genius/ (“In the last weeks, WIRED has obtained the strongest evidence yet of Satoshi Nakamoto’s true identity. All signs point to Craig Steven Wright, a man who never even made it onto any Nakamoto hunters’ public list of candidates, yet fits the cryptocurrency creator’s profile in nearly every detail.”). 8 See Satoshi Nakamoto, Bitcoin: A Peer-to-Peer Electronic Cash System (2009), https://bitcoin.org/bitcoin.pdf (“What is needed is an electronic payment system based on cryptographic proof instead of trust, allowing any two willing parties to transact directly with each other without the need for a trusted third party.”). 9 See id. (“While the system works well enough for most transactions, it still suffers from the inherent weaknesses of the trust based model.”). 10 Id. 3 Daniela Dekhtyar – Seminar Paper that product can be sold.11 Lastly, Nakomoto argued that reversibility of payments, a staple feature of online transactions cleared by a financial institution, creates “costs and payment uncertainties” for merchants whose transactions are disputed.12 Nakamoto’s solution was Bitcoin: a peer-to-peer network that would allow senders and beneficiaries of payments to transact directly with one another, without the need of a trusted third party like a financial institution. I.A. How Bitcoin Works Bitcoin has two key features. First, bitcoins are electronically created and stored. Bitcoin users create bitcoins by a process called “mining.” 13 All of the bitcoins ever created and all of the transactions ever conducted via Bitcoin are recorded in a virtual public ledger known as the “block chain.” 14 To mine for new bitcoins, a user must verify the block chain by solving a complex mathematical problem. 15 If that problem is solved successfully, 25 bitcoins are produced.16 The opportunity to verify the block chain (and as a result mine bitcoins) arises when 11 Id. 12 Id. 13 Bitcoin Project.

  • Motion Record of the Trustee (Returnable
    - 32 - cryptocurrency business. In its investigation and review of text and email communications, the Monitor noted that certain TPPs were instructed by Mr. Cotten to provide limited information to the financial institutions in relation to the intended use of the account and its association with the cryptocurrency industry to limit scrutiny by the financial institutions. 80. The Monitor identified a number of accounts that were frozen or closed subsequent to the financial institution becoming aware of the nature of the underlying transactions. The Monitor’s investigation indicates that frequently, Quadriga’s approach to addressing financial institution queries into the nature of the account usage was often to simply move on to another financial institution to avoid further questioning. 81. The Monitor’s investigation also identified many “cash” transactions where certain Users repeatedly funded their Accounts with large cash deposits. The Monitor has been advised that this involved the User physically handing cash in the form of legal tender to a representative of Quadriga. As an example, the Platform recorded $12.1 million of “In person Payments” received from one User through a series of nineteen (19) cash transactions over a 5-month period. The Monitor has been unable to verify how or if these cash deposits were appropriately deposited into the Quadriga treasury system through TPP accounts or other accounts. The Monitor has also reviewed communications which appear to indicate that Mr. Cotten sometimes credited a User’s account with a deposit with the understanding that the User would deliver cash at some point in the future. The deposits, once credited to the User’s Account, were subsequently used by the User to trade and remove Cryptocurrency off Platform.

  • Executive Summary Background Information What Is Bitcoin? What Is
    Executive Summary Details surrounding the identity of Satoshi Nakamoto and the origins of Bitcoin have emerged from a Florida court case, Kleiman v Wright. The plaintiff, Ira Kleiman, is suing the defendant, Craig Steven Wright (CSW) for the rights to Bitcoin tokens and Bitcoin related intellectual property. Ira alleges that his deceased brother Dave Kleiman was CSW’s partner in the development of Bitcoin and Bitcoin related IP. Implicit in this allegation is that CSW created Bitcoin and has access to Satoshi’s Bitcoins currently valued ~$10B. CSW has made it clear that his intention is to sell his BTC in favor of his preferred version of Bitcoin, BSV, which is more aligned with the original design. If this occurs it will have massive market ramifications on the order of hundreds of billions of dollars. Court case details support CSW’s claim to be Satoshi. This contrasts the opinion of many industry leaders who don’t believe that CSW is Satoshi or that he can follow through on his threat to sell BTC for BSV. The conflict around the Satoshi identity ties into a larger conflict about the purpose of Bitcoin and the role of law in Bitcoin. Background Information What is Bitcoin? What is BTC? Bitcoin is a revolutionary peer-to-peer network and electronic cash system. Over its 10 year ​ history, Bitcoin tokens have appreciated from being effectively worthless to having a market cap of over $315 billion. BTC is the predominant ticker symbol of the Bitcoin token. Others, like BSV and BCH exist through a process called forking.

  • Bitcoin Reveals Exchange Rate Manipulation and Detects Capital Controls
    Bitcoin Reveals Exchange Rate Manipulation and Detects Capital Controls G.C. Pieters∗ Trinity University, Economics Dept, 1 Trinity Place, San Antonio, Texas, 78212. Abstract Many countries manipulate the value of their currency or use some form of capital control, yet the data usually used to detect these manipulations are low frequency, expensive, lagged, and potentially mis-measured. I demonstrate that the price data of the internationally traded cryptocurrency Bitcoin can approximate unofficial exchange rates which, in turn, can be used to detect both the existence and the magnitude of the distortion caused by capital controls and exchange rate manipulations. However, I document that bitcoin exchange rates contain problematic bitcoin-market-specific elements and must be adjusted before being used for this purpose. As bitcoin exchange rates exist at a daily frequency, they reveal transitory interventions that would otherwise go undetected. This result also serves as verification that Bitcoin is used to circumvent capital controls and manipulated exchange rates. Keywords: Bitcoin; Exchange Rates; Black Market; Unofficial; Financial Integration; Capital Controls JEL Codes: F30, F31, F38, E42, G15, O17 ∗Corresponding author Email address: [email protected] ( G.C. Pieters) 1I am grateful for helpful comments and suggestions from Christoffer Koch and participants at the 2016 International Trade and Finance Association Conference and 2017 Liberal Arts Macroeconomics Workshop. 1. INTRODUCTION This paper is a contribution to timely, high-frequency, accurate measurement of unofficial exchange rates, de facto exchange rate regimes, and de facto capital controls. While policies that result in manipulated exchange rates|such as capital controls|may seem like a problem that distorts the trade and finance flows of only a few countries, Calvo and Reinhart(2002) found that governments display fear of floating: officially declaring they allow their exchange rates to float (a de jure floating regime), while still actively manipulating their exchange rates (a de facto managed regime).

  • Anonymity-Driven Demand for Cryptocurrency: Theory and Policy Implications
    Anonymity-Driven Demand for Cryptocurrency: Theory and Policy Implications Sophie L. Zhou* 20th April 2021 Latest version available HERE Abstract Anonymity-seeking individuals prefer cryptocurrencies for online payments, but due to know-your-customer requirements on cryptocurrency exchanges, they resort to peer-to-peer markets for purchasing cryptocurrencies. I develop a search-theoretic model capturing this phenomenon. The model allows demand for cryptocurrencies to be governed by both consumption and speculative motives, and matches empir- ical observations of Bitcoin velocity and peer-to-peer transaction share. Allowing currency competition, I show that anonymity renders fiat-money-based e-payments and cryptocurrencies imperfect substitutes. Lowering the fiat money inflation rate is insufficient for eliminating cryptocurrency demand, and raising the participation cost on cryptocurrency exchanges becomes necessary. I further analyze the optimal participation cost on cryptocurrency exchanges, weighing up the benefit of financial inclusion against the cost of illicit activities often associated with anonymity.

  • Arxiv:2010.05589V3 [Cs.DS] 31 Oct 2020 Growth of Random Trees By
    Growth of Random Trees by Leaf Attachment Nomvelo Karabo Sibisi University of Cape Town [email protected] October 2020 Abstract We study the growth of a time-ordered rooted tree by probabilistic attachment of new vertices to leaves. We construct a likelihood function of the leaves based on the connectivity of the tree. We take such connectivity to be induced by the merging of directed ordered paths from leaves to the root. Combining the likelihood with an assigned prior distribution leads to a posterior leaf distribution from which we sample attachment points for new vertices. We present computational examples of such Bayesian tree growth. Although the discussion is generic, the initial motivation for the paper is the concept of a distributed ledger, which may be regarded as a time-ordered random tree that grows by probabilistic leaf attachment. 1 Introduction In the context of this paper, a tree is an object in graph theory. In particular, we study a directed rooted tree (vertices joined by directed edges where one vertex is the root) that grows with time according to probabilistic rules. The motivation for such a study will be discussed below. In the first instance, we give a simple illustration of the growth of a directed rooted tree. arXiv:2010.05589v3 [cs.DS] 31 Oct 2020 We adopt an approach to graph theory where visual representation often takes precedence over formal description. Accordingly, Figure 1 shows a sequence of ‘snapshots’ of a tree as it grows through attachment of new vertices to existing vertices (time increases to the right in each snapshot and a directed edge from one vertex to another represents attachment of the former to the latter).
