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 actorsâ motivations. This paper finds that despite cryptocurrencyâs 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.

With the popularity of cryptocurrency like bitcoins in recent years, the social circles have been confusing whether cryptocurrency is real money essentially. Lots of voices have clarified the question from the traditional view that regards the nature of money as commodity. However, historical evidences have proved that the traditional theory deviates from the real nature of money originating from debt and is not exactly true. State Theory of Money holds the debt-based opinion on the nature of money and regards the nature of money as the debt of state, which is allowed to be the payment of tax. Therefore based on this, the paper analyzes the debt nature of money and the characteristics of cryptocurrency like bitcoins, and draws the conclusion that cryptocurrency like bitcoins is not accepted by the state as the payment of tax, not the national debt, so not the currency.

The development of information technology in the modern economy is one of the drivers of economic growth. Digital technologies are developing at an accelerating pace. Digitalization stimulates not only economic, but also social and technological progress. The impact of digital technology in different industries is not the same. The authors of the article consider such promising modern technology as Blockchain. Its advantage is that the information is protected from unauthorized modification. This transforms the system of economic relations. The level of trust increases. Opportunistic behaviour of participants in contractual relations is blocked. As a result, economic efficiency improves. These positive effects are analyzed in the case of the pharmaceutical industry. The introduction of Blockchain technologies into pharmaceuticals allows you to track all stages of production of drugs and guarantee their quality. Blockchain technology allows you to confirm the authenticity of recipes and the drugs with the help of special digital devices. The consequence of this is a reduction in the number of counterfeit drugs on the market, as well as improving the quality of medical care for the population.

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 EUâs 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.

Identifying and quantifying the drivers for adopting blockchain technologies are important for developing effective launch plan. Technology Acceptance Model (TAM) and its derivatives have been used for this purpose. However, some of these models only use a few standardized, predetermined independent variables to collectively represent the drivers. Low predictive power of TAM leads to questions on whether this restriction may detrimentally constrain the exploration of other driving factors. Some other extended models with higher R2 are considered impractical and lack of theoretical foundations. This paper demonstrates that reasonable predictive power can be achieved even with simple, practically implementable model when research targets are sampled and segmented properly. By employing a more fundamental theory, this study has also included additional variable that would normally not be considered in TAM.

Blockchain platform has given information system scholars research opportunities in understanding dynamics of convergence of technology and social context. The information system research issues are complex and require taxonomies to understand the similarities and uniqueness among objects. Developing taxonomies is a complex process that needs systematic approach. This paper is a research-in-progress. We proposed taxonomy for Blockchain platform using existing method of developing taxonomies in information systems. With the unprecedented growth led to several companies to develop the varieties of Blockchain platforms. The complexity in the implementation and understanding the technical protocols leading to difficulty face by researchers and practitioners to access their full potentials. To bridge the gap, we proposed a taxonomy of Blockchains distributed ledger platforms in order to provide a mechanism for researchers and practitioners to understand the phenomenon. Final of taxonomy contains five (5) dimensions with fifteen (15) characteristics. Our analysis discovered Blockchain platforms are designed with specific goals, which prescribe its features, i.e FinTech Blockchain platforms for financial domain.

Over the last decade, blockchain technology has facilitated a method by which a network of equipotent and equally privileged peers can jointly maintain and edit databases in an entirely decentralized manner, without any kind of an intermediary exhibiting unilateral control. As a consequence it has enabled the creation of a new type of multi-sided platform architecture with distributed governance. As the different platform provision functions are opened to free market competition rather than monopolized by a single entity, the monopoly-like pricing structure typical of platforms is overhauled. Instead, blockchain-enabled distributed platforms appear to share value more evenly between the all the different market sides connected to the platform. Our analysis reveals that blockchain technology adds new considerations to how multi-sided platform architectures should be perceived and analyzed.

This case study analyzes the impact of theory-based factors on the implementation of different blockchain technologies in use cases from the energy sector. We construct an integrated research model based on the Diffusion of Innovations theory, institutional economics and the Technology-Organization-Environment framework. Using qualitative data from in-depth interviews, we link constructs to theory and assess their impact on each use case. Doing so we can depict the dynamic relations between different blockchain technologies and the energy sector. The study provides insights for decision makers in electric utilities, and government administrations.

Low transaction cost, low level of entry, worldwide quickness, and anonymity of the transactions is the main advantage of cryptocurrency use, making it an attractive transaction media for African countries. At the same time, there are certain drawbacks of it in terms of strong volatility, lack of user-friendliness and its usage in crime. The conceptual paper explores the use of cryptocurrencies, and its potential in the African context. The research paper utilizes UTAUT 2 Model and adds key constructs for analyzing the adoption of new technology by Africans. These additional constructs include hedonistic motivation, habit and price cost. Key factors were considered in the case of African countries in order to analyze whether cryptocurrency is essential for economic growth in some economic countries. The application of UTAUT model in the case of Arica shows that performance, effort expectations, social influence are favorable for African countries while the influence of hedonic motivations and price is unfavorable for acceptance of cryptocurrencies in African countries.

By allowing networks to split, decentralized blockchain platforms protect members against hold up, but hinder coordination, given that adaptation decisions are ultimately decentralized. The current solutions to improve coordination, based on âpreminingâ cryptocoins, taxing members and incentivizing developers, are insufficient. For blockchain to fulfill its promise and out-compete centralized firms, it needs to develop new forms of âsoftâ decentralized governance (anarchic, aristocratic, democratic, and autocratic) that allow networks to avoid bad equilibria.

Platform businesses are born global, with instant access to global markets. Thanks to the algorithmic, self-executing and self-enforcing computer programmes known as smart contracts, platform businesses now also have instant access to global capital markets from birth. However, the legal status of these smart-contract-enabled funding mechanisms and smart contracts in general is not well defined. In this article, we analyse how well the formation mechanisms of the general principles of Finnish contract law can be applied to the technological framework of smart contracts. We find that depending on the case, smart contracts can create legally binding rights and obligations to their parties. We also observe that contracts have not been formerly perceived as technical boundary resources in the sense that platform ecosystems could foster broader network effects by opening their application contracting interfaces to third parties.

While contemporary technological disruption is increasingly conceptualized in terms of the logic and paradoxes of the digital platform economy, discussions of âFinTechâ have only engaged to a limited extent with these debatesâparticularly from an economic geographic standpoint. Here we fill this gap by proposing an adapted Global Financial Network (GFN) framework for conceptualizing the organizational and geographic logic of the digital platform economy in finance, and applying it to examine the impact of the digital platform model on asset management. As we will show, asset management is being profoundly disrupted by what we dub digital asset management platformsâor DAMPsâwhich encompass services including index fund and ETF provision, robo-advising, and analytics and trading support. Like other digital platforms, DAMPs do not so much leverage technology to enhance their competitiveness within markets, as to radically restructure the market itself. Also, like other platforms, their rise has produced a winner-take-all paradox of centralization through democratization that defies predictions of technology-enabled industry decentralization. However, the logic and implications of the rise of DAMPs diverges, in other respects, from non-financial digital platforms, as finance has long possessed an informational intensity and regulatory and organizational fluidity characteristic of the digital platform economy. Consequently, the digital platform model has mostly developed endogenously in asset management through incremental innovation by major financial firmsâin a process that has reinforced the position of leading incumbent asset management centers, and above all New Yorkârather than being introduced from the outside by upstart technology firms and clusters.

This paper is an attempt to analyze the role of transaction fees in a proof-of-stake cryptocurrency currently in development. The authors have employed a microeconomic, static equilibrium approach to model a market in which the cryptocurrency is exchanged for a physical good. Furthermore, the relationship between transaction capacity and the size of the network has been investigated. It has been shown that the total amount of validator capital and the number of validators can be controlled by setting a fixed fee on transactions as well as a minimum capital requirement on individual validators. The total surplus in the economy has then been optimized by setting a fee and the authors have discussed how a minimal capital requirement could be used to also optimize transaction capacity.
