Creation and Resilience of Decentralized Brands: Bitcoin & The
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. -
Segwit2x –
SegWit2x – A New Statement The Overwhelming power of SegWit2x In order to safeguard the community from an undesired chain split, the upgrade should be overwhelming, but it’s not enough. It should also ‘appear’ as overwhelming. People, businesses and services needs to be certain about what is going to happen and the risks if they won’t follow. My impression is that still too many speaking english people in the western world think the upgrade will be abandoned before or immediately after block 494784 is mined, thus they are going to simply ignore it. That could lead to unprepared patch up and confusion, while naïve users risk to harm themselves. For this reason and for the sake of the Bitcoin community as a whole, we need to show again, clearly and publicly the extent of the support to SegWit2x. We also need to commit ourselves in a widespread communication campaign. I know this is not a strict technical matter, but it could help a lot avoiding technical issues in the future. What we have to do First, we need a new statement from the original NYA signers and all the business, firms and individuals who joined the cause later. That statement should be slightly different from the original NYA though, and I am explaining why. We all know that what Bitcoin is will be ultimately determined by market forces, comprehensive of all the stakeholders involved: businesses, miners, users, developers, traders, investors, holders etc. Each category has its own weight in the process, and everybody has incentives in following the market. -
True Nyms and Crypto Anarchy
True Nyms and Crypto Anarchy Timothy C. May One of the biggest issues in cyberspace these days, one that will continue to be an issue as long as there is such a venue as the Internet, is the safety of communication from prying eyes. In the detailed and persuasive essay that follows, Tim May, formerly a physicist at Intel and one of the founding members of the Cypherpunks, discusses the big issues involved—invasion of privacy, the specter of government interference in personal affairs, the use of electronically forwarded information by a variety of people, entities, and organizations for purposes other than those intended by the forwarder … these are all issues of tremendous importance to anyone who uses the Internet —and that means just about everyone, in one way or another. In a previous age, these issues were not of such great importance, for there was never the possibility that anyone could find and gather enough information to do harm to others in the ways that are now possible with the Internet. Today, however … Read Tim May’s essay and you’ll never feel quite as safe as you did a moment before you read these pages. This article was written in 1996. 25 The Impact of True Names “True Names” came to my attention in 1986, when a friend of mine gave me a dog-eared Xerox copy and said “You need to read this.” But before I even started reading this samizdat edition, the Bluejay Books trade paperback edition appeared and that’s what I read, saving my eyesight and giving Vernor Vinge his proper cut of the action. -
Facilitating Cross-Chain Cryptocurrency Exchanges: an Inquiry Into Blockchain Technology and Interoperability with an Emphasis on Cryptocurrency Arbitrage
Eastern Michigan University DigitalCommons@EMU Senior Honors Theses & Projects Honors College 2020 Facilitating cross-chain cryptocurrency exchanges: An inquiry into blockchain technology and interoperability with an emphasis on cryptocurrency arbitrage Samuel Grone Follow this and additional works at: https://commons.emich.edu/honors Part of the Computer Sciences Commons Facilitating cross-chain cryptocurrency exchanges: An inquiry into blockchain technology and interoperability with an emphasis on cryptocurrency arbitrage Abstract Since the introduction and proliferation of the blockchain-based cryptocurrency Bitcoin, alternative cryptocurrencies also based on blockchain technology have exploded in number. It was once believed that one, or very few, cryptocurrencies would eventually dominate the market and drive out competitors. This assumption, however, was incorrect. Thousands of cryptocurrencies exist concurrently. The vast number of cryptocurrencies leads to a problem—what if the cryptocurrency that an individual possesses does not meet their current needs as well as another cryptocurrency might? The attempt to solve this problem has led to the rise of many cryptocurrency exchanges and exchange schemes. In this paper, we will discuss the motivations for an individual to be interested in exchanging two or more cryptocurrencies by describing and comparing various popular cryptocurrencies with different desirable attributes. While we will discuss these attributes, this paper will give special focus to arbitrage in particular. In addition, we will describe various cryptocurrency exchange schemes and their advantages and disadvantages. Finally, we contribute to the understanding of cryptocurrency exchangeability and interoperability by comparing the historical price data of several cryptocurrencies to determine how often arbitrage has been possible in the past.

Bitcoin, which is the first example of the growing category of money known as the cryptocurrency, is the most popular and widely accepted of them all. Bitcoin is a peer-to-peer electronic cash system that was invented by a software developer called Satoshi Nakamoto, and it is currently taking the lead amongst other digital currencies. It is an electronic payment system based on mathematical proof that is created and held electronically. Bitcoin is also a decentralized form of cryptocurrency that is independent of any central authority – meaning, there is no single institution controlling the Bitcoin network. This eBook is going to help you go beyond a basic understanding of Bitcoin and the mining of it. When you are finished reading, you’ll be ready to get started mining Bitcoins today! 4 What is Bitcoin Mining? In traditional fiat currency systems, money is printed by the government and released into circulation whenever it is needed. -
Trust and Verifiable Computation for Smart Contracts in Permissionless Blockchains
DEGREE PROJECT IN INFORMATION AND COMMUNICATION TECHNOLOGY, SECOND CYCLE, 30 CREDITS STOCKHOLM, SWEDEN 2017 Trust and verifiable computation for smart contracts in permissionless blockchains DOMINIK HARZ KTH ROYAL INSTITUTE OF TECHNOLOGY SCHOOL OF INFORMATION AND COMMUNICATION TECHNOLOGY Abstract Blockchains address trust through cryptography and consensus. Bitcoin is the first digital currency without trusted agents. Ethereum extends this technology by enabling agents on a blockchain, via smart contracts. However, a systemic trust model for smart contracts in blockchains is missing. This thesis describes the ecosystem of smart contracts as an open multi-agent system. A trust model introduces social control through deposits and review agents. Trust-related attributes are quantified in 2,561 smart contracts from GitHub. Smart contracts employ a mean of three variables and functions and one in ten has a security-related issue. Moreover, blockchains restrict computation tasks. Resolving these restrictions while maintaining trust requires verifiable computation. An algorithm for verifiable computation is developed and implemented in Solidity. It uses an arbiter enforcing the algorithm, computation services providing and verifying solutions, and a judge assessing solutions. Experiments are performed with 1000 iterations for one to six verifiers with a cheater prior probability of 30%, 50%, and 70%. The algorithm shows linear complexity for integer multiplication. The verification depends on cheater prior probability and amount of verifiers. In the experiments, six verifiers are sufficient to detect all cheaters for the three prior probabilities. Keywords: blockchain; smart contract; trust; multi-agent system; verifiable compu- tation Referat Blockchains adresserar tillit genom kryptografi och konsensus. Bitcoin är den första digitala valutan utan betrodda agenter. -
Beyond Theories: Intellectual Property Dynamics in the Global Knowledge Economy
WAKE FOREST INTELLECTUAL PROPERTY LAW JOURNAL VOLUME 9 2008 - 2009 NUMBER 2 BEYOND THEORIES : INTELLECTUAL PROPERTY DYNAMICS IN THE GLOBAL KNOWLEDGE ECONOMY CHIDI OGUAMANAM * ABSTRACT This Article critically examines the inadequacy of theoretical postulates on intellectual property. It acknowledges that theorizing around intellectual property is an important ongoing but elusive intellectual adventure that is critical for law and policy direction on intellectual property. Perhaps, at no time is this fact more obvious than in the extant post-industrial epoch or the era of Global Knowledge Economy (“GKE”). The latter is spurred by advances in bio- and digital technologies. Both phenomena drive significant shift and transition in intellectual property jurisprudence and in the tide of innovation from physical to life sciences. They also supervise implosions in new and complex domains or sites for knowledge and information generation. As its feature, the global knowledge economic order is undergirded by an institutional and structural shift in international intellectual property lawmaking and governance, provoking a serendipitous counter-regime dynamic in diverse sites for contestations around intellectual property. The pivotal role of intellectual property in the GKE presents intellectual property as an increasingly multidisciplinary subject with complex issue linkages in virtually all fronts, including public health, human rights, biodiversity, biotechnology, biopiracy, the environment, ethics, culture, indigenous knowledge, electronic commerce, and research ethos. Overall, these and many more issue linkages to intellectual property are part of the latter’s open-ended dynamics in the GKE. They are constitutive of a myriad of factors that task and shape policy and theory on intellectual property as the knowledge economy continues to unravel. -

Articles of Federation
Bitcoin Unlimited: Articles of Federation Bitcoin is at a crossroads that will determine whether it becomes a worldwide public good, embodying a trustless ledger and currency for all people, companies, and financial institutions worldwide. The Bitcoin Unlimited project seeks to provide a voice, in terms of code and hash power, to all stakeholders in the Bitcoin ecosystem. As a foundational principle, we assert that Bitcoin is and should be whatever its users define by the code they run and the rules they vote for with their hash power. This project seeks to remove existing practical barriers to stakeholders expressing their views in these ways. We see in the Bitcoin ecosystem many companies, groups and economic actors that have made large investment decisions based on maintaining the current trajectory of growth - a growth that would naturally ensue if Bitcoin is available as a public good. These include payment processors, micro-payment solutions, exchanges, merchants, and more. We recognize the importance of the mining industry and the necessity to increase transaction revenue to support its growth as the block subsidy decreases. This growth is aligned with the interests of the Bitcoin network as a whole since it increases network security. In the Bitcoin Core variant, we do NOT see a venue for these actors to formally express their desires in regards to the evolution of the network. Instead we see a project controlled by a small group of developers employed by finance-oriented for- profit startup companies, and the emergence of corporate products (Lightning network, Side-chains and permissioned ledgers) that would materially benefit from a Bitcoin network that is incapable of handling the transactional demand required for a worldwide public good. -

Transaction Fees, Block Size Limit, and Auctions in Bitcoin
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Archivio della Ricerca - Università degli Studi di Siena ISSN 2379-5980 (online) DOI 10.5915/LEDGER.2019.145 RESEARCH ARTICLE Transaction Fees, Block Size Limit, and Auctions in Bitcoin Nicola Dimitri*† Abstract. Confirmation of Bitcoin transactions is executed in blocks, which are then stored in the Blockchain. As compared to the number of transactions in the mempool, the set of transactions which are verified but not yet confirmed, available space for inclusion in a block is typically limited. For this reason, successful miners can only process a subset of such transactions, and users compete with each other to enter the next block by offering confirmation fees. Assuming that successful miners pursue revenue maximization, they will include in the block those mempool transactions that maximize earnings from related fees. In the paper we model transaction fees as a Nash Equilibrium outcome of an auction game with complete information. In the game the successful miner acts as an auctioneer selling block space, and users bid for shares of such space to confirm their transactions. Moreover, based on expected fees we also discuss what the optimal, revenue maximizing, block size limit should be for the successful miner. Consistently with the intuition, the optimal block size limit resolves the trade-off between including additional transactions (which possibly lower the unit fees collected) and keeping the block capacity limited (with, however, higher unit fees). 1. Introduction Cryptocurrencies, notably Bitcoin, have recently drawn much attention within the academic community, among investors and the public, for more than one reason, and in particular for the highly variable behavior of the Dollar/Bitcoin exchange rate. -
Assassination Politics
3 April 1997 Source: http://www.infowar.com/class_1/BELL1.html-ssi Assassination Politics by Jim Bell Part 1 I've been following the concepts of digital cash and encryption since I read the article in the August 1992 issue of Scientific American on"encrypted signatures." While I've only followed the Digitaliberty area for a few weeks, I can already see a number of points that do (and should!) strongly concern the average savvy individual: 1. How can we translate the freedom afforded by the Internet to ordinary life? 2. How can we keep the government from banning encryption, digital cash, and other systems that will improve our freedom? A few months ago, I had a truly and quite literally "revolutionary" idea, and I jokingly called it "Assassination Politics": I speculated on the question of whether an organization could be set up to legally announce that it would be awarding a cash prize to somebody who correctly "predicted" the death of one of a list of violators of rights, usually either government employees, officeholders, or appointees. It could ask for anonymous contributions from the public, and individuals would be able send those contributions using digital cash. I also speculated that using modern methods of public-key encryption and anonymous "digital cash," it would be possible to make such awards in such a way so that nobody knows who is getting awarded the money, only that the award is being given. Even the organization itself would have no information that could help the authorities find the person responsible for the prediction, let alone the one who caused the death.
