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.

This paper reviews the key features of cryptocurrencies and their underlying technology, blockchain. It becomes clear that cryptocurrencies do not fulfill the three functions of money, at least for the moment, but should instead be understood as high-risk, high-profitability securities. While there are great opportunities such as increased remittances, their potential disruption of economic activity, and particularly of monetary policy is mind-blowing. Under this premise, and keeping in mind hackers’ heists suffered by cryptocurrency exchanges, it is important to regulate cryptocurrencies. Four core questions countries should decide on are: whether they consider cryptocurrencies’ legal tender, whether they allow cryptocurrency exchanges to operate (and if so, how); whether Initial Coin Offerings (ICOs) should be allowed (and if so, how); and whether they allow mining. Several policy options are presented, both from a theoretical perspective, and as they have been implemented by countries in Asia-Pacific. While countries such as China have decided to be restrictive, others such as Japan have chosen to regulate to let the sector thrive. Such diversity may be understandable, given that is such a novel technology that still poorly understood – especially its evolution. This diversity of standards offers great room for regulatory arbitrage, and highlights a great need for global coordination on cryptocurrency regulation and supervision.

Abstract This chapter provides a discussion on some issues in blockchain finance that regulators are concerned about – an area which bitcoin promoters have remained silent about. Blockchain technology in finance has several benefits for financial intermediation in the financial system; notwithstanding, several issues persist which if addressed can make the adoption of blockchain technology in finance easier and accepted by regulators. The blockchain issues discussed in this chapter are relevant for recent debates in blockchain finance.

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.

The purpose of this study is to investigate one of the types in Fintech area, which is cryptocurrency from the perspective of Shariah. Until now, there are around 1,600 types of cryptocurrencies around the world. However, one of the most sought cryptocurrency in Malaysia is Bitcoin. Since it is still a new in Malaysia, the in-depth study on this has not yet been fully completed. By the realization to study this issue, a research has been conducted to become an eye-opener for those who want to dig deeper to gain the knowledge about this especially on the views from Islamic perspective or to be specific, from Shariah views. On the other hand, many issues arise regarding this cryptocurrency especially bitcoin. Therefore, this research will investigate the concept of money with its characteristics, and analyze if cryptocurrency does have all the characteristics of real money in it. Move forward to the next objective, this study will also explain on the Islamic perspective, and to be exact, Shariah views of cryptocurrencies as the currency or as a medium of exchange. Until now, there is still not much current views from the current scholars on this exact matters. Most of the views are regarding on whether their countries accepting it to be used or not, and the majority are the views from the government. Still, there is no specific hukm on the uses of cryptocurrencies. So, the outcome of this study will provide an important insight for potential customers who still want to invest their money in cryptocurrencies.

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.

Contracts, a set of legally negotiated rules between the transacting parties are often the prime cause of legal as well as business disputes. Due to this discord, they are generally viewed with contempt. The need to revolutionize contracts has been much felt by the attorneys and the business professionals, so as to avoid these daedal contract conflicts. This resulted in the advent of smart contracts that was led by Blockchain technology. It is a blend of legalese from lawyers and computer code. A smart contract is a versatile system capable of facilitating, automating and enforcing an agreement (i.e. contract). In this paper, we preview as well as analyze smart contract based on blockchain technology for a decentralized system.
