My most sincere gratitude goes to my graduation committee. I'd like to thank Dr. Servaas Storm who guided and helped me during the whole graduation process and was kind enough to allow me the freedom to explore a new innovative theme. I really appreciate, that you helped me screen the papers which directly guided me to an in-depth research across disciplines. I gained a lot, from the efficient discussion each time as well. Also, Dr. Filippo Santoni De Sio, was very kind to give his valuable feedback in arranging the philosophy section better. Finally, Prof. Cees van Beers was helpful in his remarks for the practical applicability of the thesis. I also would like to thank Satoshi Nakomoto (Founder, Bitcoin) whoever he is for having the courage to give to the world this new financial model for us to think and rethink about society fundamentally and move towards balanced technology decentralization. Rishabh Kapoor February 2016, Delft 3 Abstract Bitcoin is a peer to peer decentralized virtual currency, released online through a research paper in 2008 by the unknown Satoshi Nakamoto . Around the world, many countries have cautiously taken minor initiatives to address the regulatory issues, due to its rising popularity. The regulation is not seen as complete, due to the nascent and novel outlook of bitcoins, requiring time for analysis and empirical evidence. The main research question that needs to be answered, is how can governance ideas be conceptualized to support technological decentralization while protecting against illegal activities? To answer this question a literature review is performed across academia, digital media and conferences/ independent authors. From this study, ideas for frameworks are consolidated, to effectively regulate bitcoins through coalitions, analyzed with game theory. This is complemented with a theoretical understanding of the technical, political, economical and ethical issues surrounding the bitcoin ecosystem. The thesis is broadly divided into seven chapters, where initially an introduction is presented which presents the structure of the thesis, along with the research problem and its motivation. This is followed by an exploration of bitcoin's current framework, which forms the most important theoretical part of the thesis. Here, its system design, strengths, challenges and solutions to regulatory issues are detailed. Also, how bitcoin is being perceived globally across twenty nations, is presented. Being an economic system, there has been reasonable skepticism, as to its validity as a money system. This is presented in the next chapter, where its economic structure is first explored, which is followed by an analysis of bitcoin, from the perspective of both Austrian economics and Keynesian economics. Further, to understand the overall validity of a new system, the ethical impacts must be considered. This has been analyzed through two frameworks in this thesis. Firstly, as a large social experiment and secondly through a standard ethical impact assessment. Also, bitcoin has always been portrayed in the popular press, as promoting decentralization. This is critically analyzed from classical ideas of noted humanitarian M.K Gandhi and British economist M.F Schumacher. As a follow up, a modern exponential technology framework presented by Singularity University, is offered as a comparison. Interestingly, it is observed that bitcoin excels in the material aspect of decentralization but struggles in the spiritual aspect, as detailed. The major regulatory solution offered in this thesis, is through coalitions among stakeholders. For clarity, seven crisis situations are highlighted with the different payoff's (relative power) among the different members assigned, with proper reasoning and a demo game explained. Finally, conclusions and favorable recommendations are drawn , along with sections on research limitations, future research and reflections. Also, an appendix section on the major digital media outlook, is presented for two years (Aug'13- Sep'15), to explain its popular portrayal and the opinion of the general audience. Overall, it can be said that it is still early days for bitcoin and there are major critics in every domain, countering its future existence. Consistent issues with taxation, anonymity tools like TOR promoting illegal activities, its inherent economic value and price volatility exist. The internet as an information medium, is probably the only suitable precedent for bitcoin, which has been far more successful than anticipated. The benefits of bitcoin from exponentially lower transaction fees, global banking outreach, framework for decentralized asset ownership transfer and its ability to impact the Monetary Policy of ruling governments have been appreciated. With over hundred competing digital currencies, the question is certainly not if, but when they would be competitive with fiat currencies.

  • Bitcoin: Technology, Economics and Business Ethics
    Bitcoin: Technology, Economics and Business Ethics By Azizah Aljohani A thesis submitted to the Faculty of Graduate and Postdoctoral Studies in partial fulfilment of the degree requirements of MASTER OF SCIENCE IN SYSTEM SCIENCE FACULTY OF ENGINEERING University of Ottawa Ottawa, Ontario, Canada August 2017 © Azizah Aljohani, Ottawa, Canada, 2017 KEYWORDS: Virtual currencies, cryptocurrencies, blockchain, Bitcoin, GARCH model ABSTRACT The rapid advancement in encryption and network computing gave birth to new tools and products that have influenced the local and global economy alike. One recent and notable example is the emergence of virtual currencies, also known as cryptocurrencies or digital currencies. Virtual currencies, such as Bitcoin, introduced a fundamental transformation that affected the way goods, services, and assets are exchanged. As a result of its distributed ledgers based on blockchain, cryptocurrencies not only offer some unique advantages to the economy, investors, and consumers, but also pose considerable risks to users and challenges for regulators when fitting the new technology into the old legal framework. This paper attempts to model the volatility of bitcoin using 5 variants of the GARCH model namely: GARCH(1,1), EGARCH(1,1) IGARCH(1,1) TGARCH(1,1) and GJR-GARCH(1,1). Once the best model is selected, an OLS regression was ran on the volatility series to measure the day of the week the effect. The results indicate that the TGARCH (1,1) model best fits the volatility price for the data. Moreover, Sunday appears as the most significant day in the week. A nontechnical discussion of several aspects and features of virtual currencies and a glimpse at what the future may hold for these decentralized currencies is also presented.

  • Cryptocurrency: the Economics of Money and Selected Policy Issues
    Cryptocurrency: The Economics of Money and Selected Policy Issues Updated April 9, 2020 Congressional Research Service https://crsreports.congress.gov R45427 SUMMARY R45427 Cryptocurrency: The Economics of Money and April 9, 2020 Selected Policy Issues David W. Perkins Cryptocurrencies are digital money in electronic payment systems that generally do not require Specialist in government backing or the involvement of an intermediary, such as a bank. Instead, users of the Macroeconomic Policy system validate payments using certain protocols. Since the 2008 invention of the first cryptocurrency, Bitcoin, cryptocurrencies have proliferated. In recent years, they experienced a rapid increase and subsequent decrease in value. One estimate found that, as of March 2020, there were more than 5,100 different cryptocurrencies worth about $231 billion. Given this rapid growth and volatility, cryptocurrencies have drawn the attention of the public and policymakers. A particularly notable feature of cryptocurrencies is their potential to act as an alternative form of money. Historically, money has either had intrinsic value or derived value from government decree. Using money electronically generally has involved using the private ledgers and systems of at least one trusted intermediary. Cryptocurrencies, by contrast, generally employ user agreement, a network of users, and cryptographic protocols to achieve valid transfers of value. Cryptocurrency users typically use a pseudonymous address to identify each other and a passcode or private key to make changes to a public ledger in order to transfer value between accounts. Other computers in the network validate these transfers. Through this use of blockchain technology, cryptocurrency systems protect their public ledgers of accounts against manipulation, so that users can only send cryptocurrency to which they have access, thus allowing users to make valid transfers without a centralized, trusted intermediary.

  • The Economic Limits of Bitcoin and the Blockchain∗†
    The Economic Limits of Bitcoin and the Blockchain∗† Eric Budish‡ June 5, 2018 Abstract The amount of computational power devoted to anonymous, decentralized blockchains such as Bitcoin’s must simultaneously satisfy two conditions in equilibrium: (1) a zero-profit condition among miners, who engage in a rent-seeking competition for the prize associated with adding the next block to the chain; and (2) an incentive compatibility condition on the system’s vulnerability to a “majority attack”, namely that the computational costs of such an attack must exceed the benefits. Together, these two equations imply that (3) the recurring, “flow”, payments to miners for running the blockchain must be large relative to the one-off, “stock”, benefits of attacking it. This is very expensive! The constraint is softer (i.e., stock versus stock) if both (i) the mining technology used to run the blockchain is both scarce and non-repurposable, and (ii) any majority attack is a “sabotage” in that it causes a collapse in the economic value of the blockchain; however, reliance on non-repurposable technology for security and vulnerability to sabotage each raise their own concerns, and point to specific collapse scenarios. In particular, the model suggests that Bitcoin would be majority attacked if it became sufficiently economically important — e.g., if it became a “store of value” akin to gold — which suggests that there are intrinsic economic limits to how economically important it can become in the first place. ∗Project start date: Feb 18, 2018. First public draft: May 3, 2018. For the record, the first large-stakes majority attack of a well-known cryptocurrency, the $18M attack on Bitcoin Gold, occurred a few weeks later in mid-May 2018 (Wilmoth, 2018; Wong, 2018).

A Regulatory and Economic Perplexity: Bitcoin Needs Just a Bit of Regulation Daniela Sonderegger [T]here is something special about Bitcoin that makes it inherently resistant to government control. It is built on code. It lives in the cloud. It is globalized and detached from the nation state, has no own institutional owner, operates peer to peer, and its transactions are inherently pseudonymous. It cannot be regulated in the same way as the stock market, government currency markets, insurance, or other financial sectors. —Jeffrey Tucker1 INTRODUCTION Set aside all of the legal and regulatory parameters and simply take a moment to imagine a world that functions on a single digitalized currency, regulated not by a central authority, but rather by the individual users who take part in the system.

  • Trading and Arbitrage in Cryptocurrency Markets
    Trading and Arbitrage in Cryptocurrency Markets Igor Makarov1 and Antoinette Schoar∗2 1London School of Economics 2MIT Sloan, NBER, CEPR December 15, 2018 ABSTRACT We study the efficiency, price formation and segmentation of cryptocurrency markets. We document large, recurrent arbitrage opportunities in cryptocurrency prices relative to fiat currencies across exchanges, which often persist for weeks. Price deviations are much larger across than within countries, and smaller between cryptocurrencies. Price deviations across countries co-move and open up in times of large appreciations of the Bitcoin. Countries that on average have a higher premium over the US Bitcoin price also see a bigger widening of arbitrage deviations in times of large appreciations of the Bitcoin. Finally, we decompose signed volume on each exchange into a common and an idiosyncratic component. We show that the common component explains up to 85% of Bitcoin returns and that the idiosyncratic components play an important role in explaining the size of the arbitrage spreads between exchanges. ∗Igor Makarov: Houghton Street, London WC2A 2AE, UK.

First, we doc- ument large, recurrent arbitrage opportunities in cryptocurrency prices relative to fiat currencies across exchanges that often persist for weeks. The total size of arbitrage prof- its just from December 2017 to February 2018 is above $1 billion. Second, arbitrage opportunities are much larger across than within regions, but smaller when trading one cryptocurrency against another, highlighting the importance of cross-border cap- ital controls. Finally, we decompose signed volume on each exchange into a common component and an idiosyncratic, exchange-specific one. We show that the common component explains up to 85% of bitcoin returns and that the idiosyncratic compo- nents play an important role in explaining the size of the arbitrage spreads between exchanges. ∗Igor Makarov: Houghton Street, London WC2A 2AE, UK.

  • “The Blockchain Folk Theorem”
    17‐817 Revised January 2018 “The blockchain folk theorem” Bruno Biais, Christophe Bisière, Matthieu Bouvard and Catherine Casamatta The blockchain folk theorem∗ Bruno Biaisy Christophe Bisièrez Matthieu Bouvard§ Catherine Casamatta{ January 5, 2018 Abstract Blockchains are distributed ledgers, operated within peer-to-peer networks. If reliable and stable, they could offer a new, cost effective way to record transactions, but are they? We model the proof-of-work blockchain protocol as a stochastic game and analyse the equilibrium strategies of rational, strategic miners. Mining the longest chain is a Markov perfect equilibrium, without forking, in line with Nakamoto (2008). The blockchain protocol, however, is a coordination game, with multiple equilibria. There exist equilibria with forks, leading to orphaned blocks and persistent divergence between chains. We also show how forks can be generated by information delays and software upgrades. Last we identify negative externalities implying that equi- librium investment in computing capacity is excessive. ∗Many thanks for helpful comments to our editor I.
