Cryptocurrency, or digital currency that utilizes blockchain technology and cryptography to encode transactions, has excited many with the promise of minimizing governance. Although the structure of cryptocurrency is inherently decentralized, cryptocurrency relies upon complex relationships between different actors with various functions and roles.. The execution of cryptocurrency thus depends on the mutually satisfying interactions of these actors, who form the basis for non-technical governance structures.\nThis paper investigates the extent to which technical governance mitigates traditional governance problems by examining the governance structures of two cryptocurrencies. It first gives background into the origin and technical value proposition of cryptocurrency, as well as governance theory, before analyzing Bitcoin and Ethereum to understand whEther technology mitigates actors’ motivations. This paper finds that despite cryptocurrency’s promise of minimizing governance, both Bitcoin and Ethereum rely heavily on trust networks, indicating that elements of non-technical governance are, in fact, crucial to their effectiveness.

As technology improves and economies become more globalized, the concept of currency has evolved. Bitcoin, a cryptographic digital currency, has been embraced as a secure and convenient type of money. Due to its security and privacy for the user, Bitcoin is a good tool for conducting criminal trades. The Financial Crimes Enforcement Network (FinCEN) has regulations in place to make identification information of Bitcoin purchasers accessible to law enforcement, but enforcing these rules with cash-for-Bitcoin traders is difficult. This study surveyed cash-for-Bitcoin vendors in Oklahoma, Texas, Arkansas, Missouri, Kansas, Colorado, and New Mexico to determine personal demographic information, knowledge of and compliance with FinCEN regulations, and opinions regarding government control of currency and willingness to work with law enforcement among vendors.

This paper incorporates blockchain activities into the broader remit of entangled political economy theory, emphasising economic and other social phenomena as the emergent byproduct of human interactions. Blockchains are a digital technology combining peer-to-peer network computing and cryptography to create an immutable decentralised public ledger. The blockchain contrasts vintage ledger technologies, either paper-based or maintained by in-house databases, largely reliant upon hierarchical, third-party trust mechanisms for their maintenance and security. Recent contributions to the blockchain studies literature suggest that the blockchain itself poses as an institutional technology that could challenge existing forms of coordination and governance organised on the basis of vintage ledgers. This proposition has significant implications for the relevance of existing entangled relationships in the economic, social and political domains. Blockchain enables non-territorial ‘crypto-secession’, not only reducing the costs associated with maintaining ledgers, but radically revising and deconcentrating data-conditioned networks to fundamentally challenge the economic positions of legacy firms and governments. These insights are further illuminated with reference to finance, property and identity cases. Entangled political economy provides a compelling lens through which we can discern the impact of blockchain technology on some of our most important relationships.

Continuous monitoring of patient's physiological signs has the potential to augment traditional medical practice, particularly in developing countries that have a shortage of healthcare professionals. However, continuously streamed data presents additional security, storage and retrieval challenges and further inhibits initiatives to integrate data to form electronic health record systems. Blockchain technologies enable data to be stored securely and inexpensively without recourse to a trusted authority. Blockchain technologies also promise to provide architectures for electronic health records that do not require huge government expenditure that challenge developing nations. However, Blockchain deployment, particularly with streamed data challenges existing Blockchain algorithms that take too long to place data in a block, and have no mechanism to determine whether every data point in every stream should be stored in such a secure way. This article presents an architecture that involves a Patient Agent, coordinating the insertion of continuous data streams into Blockchains to form an electronic health record.

Blockchain is emerging as a game changing technology in many industries. Although it is increasingly capturing the business community’s attention, a comprehensive overview of commercially available applications is lacking to date. This paper aims to fill this gap. Firstly, we propose a structured approach to assess the application landscape of blockchain technologies. To build our framework, we relied on largely accepted classifications of blockchains, based on protocols, consensus mechanisms and ownership, as well as on the most cited application areas emerging from the literature. Secondly, we applied the framework on a database of 460 released blockchains. The analysis confirms a dominance of applications for cryptocurrencies, financial transactions and certification purposes, with a prevalence of permissionless platforms. We also found new application fields that go far beyond the seven initial areas addressed by the current body of knowledge, leading to some interesting takeaways for both practitioners and IS researchers.

Blockchain is a relatively new technology created for Bitcoin’s network to store transaction records happening in it. The system is redundant and distributed, making it difficult for corrupt transactions. Without doubt the greatest use case of this technology is cryptocurrencies, however is wrong to restrict this tool only to the financial area. Many use cases are also being developed for business areas like digital identity and technological areas like IoT and many other areas. Due to the complexity, privacy and bureaucracy of certain processes in many areas a new technology rise called Smart Contracts, computational code programmable to meet certain conditions. These digital contracts act like traditional contracts, with the difference of its automaticity, where the need for a notary and certified people to validate signatures can be erased. So, the point of this thesis is to understand the concept of Blockchain and Smart Contracts and how they can be integrated together in other business and technological areas to improve and increase the efficiency of the organizational processes. After that, to create a demonstration case that show all the potential behind these technologies in a business area.

Several years after the inception of the most dominant cryptocurrency, bitcoin, the European Central Bank in 2015 indicated the need for establishing legal clarity by relevant authorities through explaining how the current legal framework applies to cryptocurrencies. Three years later, no meaningful step has been taken by any of the European Union (EU) institutions including the parliament. By examining the EU’s legal framework governing payments services, including the Single Euro Payment Area (SEPA) Regulation, the Electronic Money Directive, the Payment Services Directive and the proposed AML/CTF Directive, this article concludes that (a) because the existing payment services laws apply to payments effected in currencies (legal tenders) and cryptocurrencies are not defined as currencies under the EU law or the laws of member states, they do not cover cryptocurrencies. It also argues that it is impossible to design sui generis payments services law for cryptocurrencies without curbing their essential features, especially decentralization. Lastly, the article proposes centralization and the creation of state cryptocurrency as possible solutions moving forward and examines their strengths and challenges.

On February 6, 2017, the Bangko Sentral ng Pilipinas (“BSP”) issued the Guidelines for Virtual Currency Exchanges (BSP Circular No. 944, or “Circular”), providing the rules and regulations governing operations of Virtual Currency (“VC”) Exchanges in the Philippines. The Circular is incorporated as Section 4512N of the Manual of Regulations for Non-Bank Financial Institutions (“MORNBFI”). This article provides an overview of the Circular.

This paper examines the market for initial coin offerings (ICOs). ICOs are smart contracts based on blockchain technology that are designed for entrepreneurs to raise external finance by issuing tokens without an intermediary. Unlike existing mechanisms for early-stage finance, tokens potentially provide investors with rapid opportunities thanks to liquid trading platforms. The marketability of tokens offers novel insights into entrepreneurial finance, which I explore in this paper. First, I document that investors earn on average 8.2% on the first day of trading. However, about 40% of all ICOs destroy investor value on the first day of trading. Second, I explore the determinants of market outcomes and find that management quality and the ICO profile are positively correlated with the funding amount and returns, whereas highly visionary projects have a negative effect. Among the 21% of all tokens that get delisted from a major exchange platform, highly visionary projects are more likely to fail, which investors anticipate. Third, I explore the sensitivity of the ICO market to adverse industry events such as China's ban of ICOs, the hack of leading ledgers, and the marketing ban on FaceBook. I find that the ICO market is highly susceptible to such environmental shocks, resulting in substantial welfare losses for investors.

36 Yale Journal on Regulation 735 (2019).Fintech is the hottest topic in finance today. Recent advances in cryptography, data analytics, and artificial intelligence are visibly “disrupting” traditional methods of delivering financial services and conducting financial transactions. Less visibly, fintech is also changing the way we think about finance: The rise of fintech is gradually recasting our collective understanding of the financial system as simply another sphere of normatively neutral information technology and objective computer science. By making financial transactions faster, cheaper, and more easily accessible, fintech seems to promise a micro-level “win-win” solution to the financial system’s many ills.This Article challenges such narratives and presents an alternative account of fintech as a systemic, macro-level phenomenon. Grounding the analysis of evolving fintech trends in a broader institutional context, the Article exposes the normative and political significance of the current fintech moment. It argues that the arrival of fintech enables a potentially decisive shift in the underlying public-private balance of powers, competencies, and roles in the financial system.In developing this argument, the Article makes three principal scholarly contributions. First, it introduces the concept of the New Deal settlement in finance: a fundamental political arrangement, in force for nearly a century, pursuant to which profit-seeking private actors retain control over allocating capital and generating financial risks, while the sovereign public bears responsibility for maintaining systemic financial stability. Second, the Article advances a novel conceptual framework for understanding the deep-seated financial dynamics that have eroded the New Deal settlement in recent decades. In particular, it offers a working taxonomy of principal mechanisms that both (a) enable private market actors to continuously synthesize tradable financial assets and scale up trading activities, and (b) undermine the public’s ability to manage the resulting system-wide risks. Finally, the Article shows how and why specific fintech applications – cryptocurrencies, distributed ledger technologies, digital crowdfunding, and robo-advising – are poised to amplify the effect of these destabilizing mechanisms, and thus potentially exacerbate the tensions and imbalances in today’s financial markets and the broader economy. It is this potential that renders fintech a public policy challenge of the highest order.
