Blockchain technology refers to a digital, immutable, distributed ledger that registers completed transactions in a well-ordered manner and near real time. Blockchain security creates a decentralized environment that bars any third-party organization from controlling the cryptographically validated transactions and data. Blockchain technology fosters business innovation by creating a peer-to-peer networking that prevents one central server from accessing as well as processing data belonging to all companies in the network. Cryptocurrency can be defined as a digital asset built to facilitate completed transactions using cryptography. It helps in providing protection to the completed transactions and controlling the creation of additional units of the currency. In the recent years, the application of blockchain technology has been associated with governance. Blockchain governance has been applied in different fields; for example, it can be used to create permanent laws that cannot be violated by any third party.

Financial Aspects of Alternative Payment Systems from the Point of View of Money Laundering Abstract The aim of this thesis is to provide a general overview of the current state of alternative payment systems with regard to their inclusion in the financial market, their properties and potentials for wider use, and to evaluate their possibilities to more effectively combat money laundering, terrorist financing and the proliferation of weapons of mass destruction. In the first chapter, the thesis explains the broader context with regard to financial systems, especially within the money market systems focusing on retail, while providing a deeper explanation of the context of European law and Czech law. The second chapter is focused on closer analysis of alternative payment systems with regard to their use. Alternative payment systems are divided into two basic categories for centralized alternative payment systems and decentralized alternative payment systems. The category of centralized alternative payment systems corresponds to the current conventional financial market, taking into account the innovations that have emerged in recent years. Decentralized alternative payment systems are based on the DLT Blockchain technology and the Islamic Hawala payment system is analyzed as a purely informal, decentralized...

A vast digital eco-system of entrepreneurship and exchange has sprung up with Bitcoin’s digital infrastructure at its core. We explore the worldwide spread of infrastructure necessary to maintain and grow Bitcoin as a system (Bitcoin nodes) and infrastructure enabling the use of bitcoins for everyday economic transactions (Bitcoin merchants). Specifically, we investigate the role of legal, criminal, financial and social determinants of the adoption of Bitcoin infrastructure. We offer some support for the view that the adoption of cryptocurrency infrastructure is driven by perceived failings of traditional financial systems, in that the spread of Bitcoin infrastructure is associated with low trust in banks and the financial system among inhabitants of a region, and with the occurrence of country-level inflation crises. On the other hand, our findings also suggest that active support for Bitcoin is higher in locations with well-developed banking services. Finally, we find support for the view that bitcoin adoption is also partly driven by cryptocurrencies’ usefulness in engaging in illicit trade.

The phenomenon of transnational crimes such as money laundering, drug trafficking, and terrorist financing remains a persistent problem for the international community and for individual states. Though existing efforts to combat transnational crimes are by no means perfect, the recent iteration of financial technology – cryptocurrencies – presents a potential alternative means for circumventing the regulatory measures that inhibit transnational crimes. Most features of traditional banking facilities are absent in cryptocurrencies: transactions therein are considered to be relatively anonymous, cryptocurrencies are also decentralized, and their use lacks any formal oversight. Thus, cryptocurrencies could be considered a further complication to the already challenging problem faced by regulatory and enforcement agencies in striving to combat transnational crimes. To date, the degree to which cryptocurrencies remain susceptible to exploitation for criminal purposes is still the subject of much debate. Therefore, this thesis will contribute to this ongoing conversation by examining the extent to which the use of cryptocurrencies facilitates transnational crimes and in turn circumvent the existing global anti-money laundering (AML) regime. Using a New Legal Realism theoretical lens, this thesis interrogates how the complex international AML framework could be interpreted, in the first instance, to apply to cryptocurrency-facilitated money laundering. This thesis also provides an overview of cryptocurrencies using Bitcoin as a case study. Given the emerging nature of cryptocurrencies, Bitcoin, as the first fully developed and widely used cryptocurrency network, is used to highlight the operating systems of cryptocurrencies. Furthermore, this work draws from the criminological discipline to explain the attractiveness of cryptocurrencies for money laundering to facilitate transnational crime. Relying on a number of criminological theories, this thesis demonstrates the importance of regulating cryptocurrencies while the problem of its illicit use is still at a nascent stage. In this case cryptocurrencies, in the absence of cohesive regulation, could become attractive to criminals seeking alternative avenues to launder the proceeds of their crimes. Thus, this thesis contributes original insights to the discussion of new techniques for facilitating transnational crimes by demonstrating through interpretation, how cryptocurrencies could be brought within the application of the existing AML regime as it is.

For many, the appeal of bitcoin is in its detachment from government regulation. \nHowever, the Coffee bonding theory, which initially arose in the context of foreign \nstocks, suggests certain benefits of regulation for bitcoin, including increased \nlegitimacy. By invoking the Coffee bonding theory, this Article offers another \nperspective on the regulation of bitcoin.

The purpose of this research is to demonstrate how public blockchains offer a greater degree of censorship resistance over traditional web-based information broadcasting mechanisms, and a comparison of existing options. Public blockchains present a means to mitigate censorship from nation states through both a broadcasting and data storage mechanism. They are costly to attack and difficult to remove from the public due to their distributed and accessible nature. A recent incident in China proved the worth of public blockchains by forcing the distribution of a censored letter describing harassment by Peking University into an Ethereum transaction by an anonymous individual or party. The Chinese government censored the letter on popular centralized services such as WeChat, but was unable to censor it once posted to the Ethereum blockchain. Through the demonstration of the letter’s presence on Ethereum as well as the act of placing it on other public blockchains, this research highlights the importance of how public blockchains will continue to be a vessel for the protection of information well into the future.

'It has the capacity to change everything - the way we work, the way we learn and play, even, maybe, the way we sleep or have sex,' wrote British entrepreneur and author Matt Symonds of his prediction for the internet in The 'Economist' in 1999. 'Within a few years, the internet will turn business upside down. Be prepared - or die.'

The purpose of this study is to perform a systematic literature review on Bitcoin and unveil its upsides, downside and divergent views from previous studies. The paper presents a systematic literature review of key studies published on Bitcoin between 2008 and 2019. The focus is given to three topics: benefits of Bitcoin; its shortcomings; and divergent views presented by previous cryptocurrency scholars in details. The results indicate that Bitcoin offers four key benefits—its acceptance as a digital currency, effective portfolio diversifier, hedging capabilities and higher security. Literature review revealed five major shortcomings of Bitcoin—weak substitute for traditional currency, higher volatility, idiosyncratic risks, uncertain regulatory impact and its exogenous supply. Finally, the review reveals three major areas wherein cryptocurrency scholars found to have divergent view—acceptance of its hedging capabilities across regions and portfolios, consensus on Bitcoin as highly secured and safe asset and, general acceptance of Bitcoin as a substitute of traditional currencies.

An analyse of bolivar/bitcoin trading activity indicates that Bitcoin trading in Venezuela is more a reflection of a survival technique rather than an investment strategy with the median transactions price significantly smaller than the medians in the Argentine peso, the Brazilian real and the UK pound. A large number of very small trades point to the practice of exchanging only as many bitcoins as is necessary for immediate use, with inflation as high as 3-4%/day. An analysis of the size of transactions in bitcoins also points to much smaller bitcoin transactions in the bolivar compared to the peso, real and pound. While Bitcoin transactions in the real and the pound indicate a range of trading opportunities from small to large transactions, peso/bitcoin transactions indicate a currency that may be at the start of a journey not dissimilar to the bolivar as transactions start to get smaller in 2018. This analysis supports the anecdotal evidence that bolivar/bitcoin trading is used as a survival technique in a country with a failing economy and worthless fiat currency

Blockchain is a relatively new technology originally created to store Bitcoin’s transaction records. The system is highly redundant and distributed, making it very difficult for fraudulent financial transactions. While cryptocurrencies might be the most well-known use case of blockchain technology, it is wrong to assume that this technology is restricted to the financial area. Indeed, many blockchain use cases are being developed today in different areas. Due to the complexity of certain processes, a new technology associated to blockchain has appeared – smart contracts. These digital contracts act like traditional contracts, with the major difference being their automaticity. In this article, we aim to discuss how blockchain and smart contracts may be used together in order to improve organizational operations. More specifically, we demonstrate how these technologies might be used to develop a solution that avoids certain types of fraud in the area of vehicle insurance.
