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. -
Melanie Swan
Blockchain Blockchain Bitcoin is starting to come into its own as a digital currency, but the blockchain technology behind it could prove to be much more significant. This book takes you beyond the currency (“Blockchain 1.0”) and smart contracts (“Blockchain 2.0”) to demonstrate how the blockchain is in position to become the fifth disruptive computing paradigm after mainframes, PCs, the Internet, and mobile/social networking. Author Melanie Swan, Founder of the Institute for Blockchain Studies, explains that the blockchain is essentially a public ledger with potential as a worldwide, decentralized record for the registration, inventory, and transfer of all assets—not just finances, but property and intangible assets such as votes, software, health data, and ideas. Topics include: ■ Concepts, features, and functionality of Bitcoin and the blockchain ■ Using the blockchain for automated tracking of all digital endeavors ■ Enabling censorship-resistant organizational models ■ Creating a decentralized digital repository to verify identity ■ Possibility of cheaper, more efficient services traditionally provided by nations ■ Blockchain for science: making better use of the data-mining network ■ Personal health record storage, including access to one’s own genomic data ■ Open access academic publishing on the blockchain Melanie Swan founded and participated in new markets startups GroupPurchase This book is part of an ongoing O’Reilly series.

Report Arcane Crypto
Arcane Crypto Report The Institutionalisation of Bitcoin 10 years ago, Satoshi Nakamoto published a paper about a peer-to-peer electronic cash system on an obscure email list for cryptographers. A system that would make trusted third parties superfluous and remove the need for banks and financial institutions to facilitate economic transactions. Few could have predicted the magnitude that followed. Hype, bubble, price collapse and soon to be dead, was the conclusion by many during the crash in 2018. Still, as exemplified by the projects summarised in this report, bitcoin is anything but dead. Despite collapsing prices there has never been more people, bigger institutions or more money betting on bitcoin and cryptocurrencies than right now. Financial institutions, tech giants and regulators have joined the bitcoin ecosystem alongside the cypher punks, libertarians and start-ups. Like the lion and the impala, the different players might have a different vision. Still, they all have their role to play in this ever evolving and growing ecosystem.

Assessment of Quantum Threat to Bitcoin and Derived Cryptocurrencies Stephen Holmes, Liqun Chen
1 Assessment of Quantum Threat To Bitcoin and Derived Cryptocurrencies Stephen Holmes, Liqun Chen University of Surrey Abstract—All cryptocurrencies are not the same. Today, they automate this approach making this almost invisible to users. share a common quantum vulnerability through use of non-quantum In order to keep the disclosure time of a valid address in a safe Elliptic Curve Digital Signature Algorithm (ECDSA) digital cryptocurrency blockchain as short as possible, a public key signatures yet they have very different risks of quantum attack. The risk of attack for a cryptocurrency depends on a number of identified can be hidden by using a cryptographic hash function or a factors such as the block interval time, the vulnerability to an attack pair of two hash functions, e.g. in bitcoin two hash functions that delays the time for an unprocessed transaction to be completed SHA256 and RIPEMD160 are used [3]. and the behaviour of a cryptocurrency user to increase the cost of The quantum attack that is a common threat to all ECDSA- a quantum computer attack. Shor’s algorithm can be used to break based cryptocurrencies can only be performed during the ECDSA signatures with a quantum computer. This research addresses the two questions: When will a quantum computer be powerful disclosure of a public key and signature to enable movement enough to execute Shor’s algorithm? How fast would a quantum of cryptocurrency funds. A window of opportunity exists until computer need to be to break a specific cryptocurrency? In this paper the unprocessed transaction is included in a block. -

Tokenomics: Dynamic Adoption and Valuation∗
Tokenomics: Dynamic Adoption and Valuation∗ Lin William Congy Ye Lix Neng Wangz First Draft: February 4, 2018 This Draft: July 30, 2018 Abstract We provide a dynamic asset-pricing model of (crypto-)tokens on (blockchain-based) platforms, and highlight their roles on endogenous user adoption. Tokens intermediate transactions on decentralized networks, and their trading creates an inter-temporal complementarity among users, generating a feedback loop between token valuation and platform adoption. Consequently, tokens capitalize future platform growth, ac- celerate adoption, and reduce user-base volatility. Equilibrium token price increases non-linearly in platform productivity, user heterogeneity, and endogenous network size. The model also produces explosive growth of user base after an initial period of dor- mant adoption, accompanied by a run-up of token price volatility. We further discuss how our framework can be used to discuss cryptocurrency supply, token competition, and pricing assets under network externality.
