We demonstrate that the Bitcoin Script language allows not only for primitive recursion, but in the deployment of an Ackerman function and hence the ability to simply recurse in Bitcoin script, we show that the script system is Turing complete. From this, we introduce a new class of Turing Machine, the PTTM or probabilistic Total Turing machine and note that Bitcoin acts as a decider or Total Turing Machine which allows us to find a NIZKPoK that can act as a TM based verifier to a Non-Interactive Proof that is run on an external and non-associated TM as a proof system. Bitcoin can extend to securely offer contracts such as best fit solutions to common logistic systems and optimisation problems including the Travelling Salesman class of problems and to the optimisation of systems. This can be offered as an open or time bound contract that guarantees payment and can be solved which allowing Pseudonymity of the bidder.
In the knowledge society, a new economy is emerging, New Economy, which also encompasses the Internet economy in the form of e-bussines, which is why the economy is the economy of information society and knowledge. So, in a knowledge-based technology, a new digital coin was also needed in the field of electronic payments, thus creating the virtual currency BITCOIN (BTC), which in a moto translation is the bit of the bit (the unit of measure of the amount of information). It is a decentralized electronic payment system and a digital encrypted opensurce created in 2009 by Satoshi Nakamoto. The need to create Bitcoin (BTC) was to ensure investment protection and free business finance, without resorting to financial institutions and beyond any constraints and regulations. The Bitcoin name also refers to the opensource program for using these coins, as well as the peer-to-peer (peer-to peer) network it forms. Currently, even if he has many opponents and has gone through several difficult times, Bitcoin seems to survive and offer new technology with revolutionary use possibilities. The concept of the digital coin fits perfectly with the ever-changing world, dominated by mobile and omnipresent technology. Compared to Bitcoin or another digital coin, any visit to the bank seems like a trip to another century, an era of time lost at the counter completing dozens of unnecessary papers.
Despite a world awash with liquidity, \n large infrastructure supply gaps exist across developing and \n emerging markets. Infrastructure has been largely \n decentralized to subnational governments in many countries, \n and many policymakers are keenly interested in developing \n subnational bond markets to give subnational governments \n access to private financing for infrastructure. Despite \n this, the transaction costs of bond issuance are still \n prohibitive for many subnational governments to access \n financing. Pooled financing, through regional infrastructure \n funds, municipal funds, or bond banks, has become a \n sought-after solution for helping subnational governments \n access private financing for infrastructure. In the United \n States, municipal bond banks that were established since the \n 1970s have become a cost-effective and stable model for \n expanding subnational financing for many small \n municipalities, while maintaining strong credit ratings with \n virtually no defaults from sub-borrowers. The municipal bond \n banks have been successful in lowering financing costs for \n many small, unrated local governments, with loan sizes as \n low as less than $50,000. This paper examines the policies \n and structures that have made pooled financing successful in \n the United States, including regulatory frameworks, \n governance and managerial systems, the role of project \n appraisal, operations and pricing, and managing the default \n risks of borrowers. The paper also explores broader lessons \n for developing countries that are interested in establishing \n pooled financing for subnational infrastructure.
In less than a calendar year, initial coin offerings or “ICOs” have become the fastest growing capital market in the world. In 2016, an entity called The DAO raised $160 million by selling crypto-tokens to over 15,000 individual purchasers around the globe. This massive fund raise would give rise to an entirely new capital ecosystem. In 2017, initial coin offerings would explode, raising a collective $3.5 billion in just the first three quarters of the year. All of this was done without a single registration being filed with the SEC, and many of these initial coin offerings — including several $100 million raises — were based on little more than a white paper and few lines of sample code. Welcome to the new Digital Wild West. With the seemingly overnight success of this new funding mechanism, there is little if any legal scholarship addressing initial coin offerings and how, or if, such offerings should be regulated. This article provides a non-technical legal audience with a foundational understanding of how the blockchain works, and the role initial coin offerings play in this new economic ecosystem. The overarching thesis of the article is that our current securities law framework, a framework that dates to the days of the great depression, is ill-equipped to handle this new world of decentralized, global, pseudonymous fund raises on public blockchains. Instead, governmental regulators should be working with core development teams to build a regulatory framework that integrates investor protections directly into the computer code governing these systems. By embracing “code as law,” both regulators and core development teams can protect the innovation being funded by initial coin offerings, while at the same time injecting some much needed investor protections into this new ecosystem. This article begins with an introduction to the coming decentralized world, including an overview of both public blockchain technology as well the Ethereum platform, the primary public blockchain upon which initial coin offerings are being deployed. Central to this introduction is an explanation of how the decentralization and disintermediation brought by the blockchain has the potential to dramatically reshape our economic and social systems. Next, the article explores the recent explosion of initial coin offerings, discussing how these offerings are structured, and how this new funding mechanism, if developed properly, has the promise of democratizing opportunities for economic innovation. The article then examines the SEC’s early statements on initial coin offerings to illustrate the potential problems with applying a dated legal framework to this new technology. Finally, the article concludes that the traditional securities law framework is ill suited for the coming decentralized world because the SEC’s enforcement power over global blockchain platforms is limited. Recognizing that external legal frameworks cannot be forced upon public blockchain platforms, the article argues for a collaborative process where governmental regulators work with core development teams to build a regulatory framework into the very fabric of these platforms, thereby providing investors protection, while at the same time embracing the concept of code as law.
Background: It is written much about the virtual currency in the media. Bitcoin is a virtual currency that is beginning to be used as payment for the purchase of goods and services. There are risks associated with virtual currencies just like traditional payments are, in some ways, these risks are similar, while they aredifferent in other ways. Purpose: The purpose of this study is to identify the risks that may arise when Bitcoin are used to make payments and to analyze how these risks can be managed. I will also analyze how Bitcoin works as payment. Method: Inthis study I has assumed an abductive method. The research approach has been made by triangulation where the aim is answered on the basis of a quantitative and qualitative approach. I have collect empirical data through a literature study, a survey and semi-structured interviews. Conclusion: Bitcoin is still in development stage, because of that I cannot make any conclusion on whether it will exist in the future. Bitcoin as payment is connected with a lot of possibilities in terms of businesses to gain a competitive advantage by offering Bitcoin as payment and financial institutions have a tougher competition. Other benefits of Bitcoin is that transaction costs are low and users' privacy is protected. Some disadvantages of Bitcoin is that it is in a legal gray area, high volatility, high entry barriers and low range of products and services. Keywords: Bitcoin, business, virtual currencies, risks, opportunities, benefits, crypto currency.

According to the World Economic Forum, by 2025 10% of the worldâs GDP (currently about $100 trillion) may be on blockchain. Blockchain technology is described as a distributed ledger technology (DLT) underpinned by five fundamental principles: decentralization, peer-to-peer transmission; transparency with pseudonymity; irreversibility of records; and computational logic. Despite blockchainâs transformative potential, it is unclear how Blockchain applications are implemented across industries and product/service categories. The purpose of the paper is to discuss the general challenges, risks, and implications related to blockchain implementation and adoption by the private and public sectors. We discuss how blockchain should overcome multiple barriersâtechnological, governance, organizational and socialâfor its widespread adoption. Mainly, the regulatory uncertainty, scalability and performance, interoperability, data privacy, security, legacy systems and the skills gap barriers to adoption are examined. Moreover, the socioeconomic implications of blockchain are discussed mainly the financial, economic, social and institutional impacts.
Abstract In this work we study the continuity of four different notions of asymptotic behavior for a family of non-autonomous non-classical parabolic equations given by { u t − γ ( t ) Δ u t − Δ u = g ϵ ( t , u ) , in Ω u = 0 , on ∂ Ω . $$\begin{array}{} \displaystyle \left\{ \begin{array}{*{20}{l}} {{u_t} - \gamma \left( t \right)\Delta {u_t} - \Delta u = {g_\varepsilon }\left( {t,u} \right),{\;\text{in}\;}\Omega } \hfill \\ {u = 0,{\;\text{on}\;}\partial \Omega {\rm{.}}} \hfill \\ \end{array}\right. \end{array}$$ in a smooth bounded domain Ω ⊂ ℝ n , n ⩾ 3, where the terms g ε are a small perturbation, in some sense, of a function f that depends only on u .
The approach to understanding electronic money and their types on the basis of cryptographic technologies and data encryption protocols is disclosed in the article. Electronic money is becoming more popular among Internet users, as payment transactions and additional revenues. This determines the formation of new economic categories and characteristics, which gradually enter the system of modern development of society. Among them we can point out crypto technology, cryptosystems, and crypto economy, trade and money relations. They are based on bitcoin and alternative crypto assets. Modern approaches to understanding crypto currencies and their classification features are analysed. Characteristics that show the advantages over fiat money are given. The directions for the development of the crypto currency market and its surrogates are outlined.
Introduction. At the present stage, Ukraine is steadfastly concentrating its efforts on fulfilling its international legal obligations, including on issues of development of local and regional democracy. An important role in these processes is played by the reform of local self-government and territorial organization of power in accordance with the basic provisions of the European Charter of Local Self-Government, which has become an integral part of the national legislation in this area. Purpose. The purpose of the study is to analyze the actual revenues of local budget revenues of the Ternopil region as a whole and the combined territorial communities and the city of Ternopil in particular. In addition, the task of analyzing the dynamics of individual sources of local budget revenues and determining the possible problems of budget formation in 2017 is set. Results. Summarizing the study, it should be noted that as a result of the decentralization reform, the system of financing has been changed in the country, and tools have been created that allow local authorities to effectively address and prevent problems on the ground. Conclusion. The further introduction of a decentralization policy should become an effective factor in stabilizing the socio-economic situation, overcoming the financial crisis, overcoming the contradictions between different levels of government, organizing relations between the center, regions and territorial communities on the basis of the division of responsibilities and competences, as well as partnerships in the area of providing citizens Ukraine with state and local benefits, and to increase the efficiency of using budget funds at all levels of government.

EU Regulation / /EC concerning common rules for internal market in electricity calls upon % of EU electricity consumers to be equipped with smart metering systems by , provided that a positive economic assessment of all long-term costs and benefits to the market and the individual consumer is guaranteed. Understanding the impact that smart metering systems may have on the electricity stakeholders (consumers, distribution system operators, energy suppliers and the society at large) is important for faster and e ective deployment of such systems and of the innovative services they o er. For this purpose, in this paper an agentbased model is developed, where the electricity consumer behaviour due to di erent smart metering policies is simulated. Consumers are modelled as household agents having dynamic preferences on types of electricity contracts o ered by the supplier. Development of preferences depends on personal values, memory and attitudes, as well as the degree of interaction in a social network structure. We are interested in exploring possible di usion rates of smart metering enabled services under di erent policy interventions and the impact of this technological di usion on individual and societal performance indicators. In four simulation experiments and three intervention policies we observe the di usion of energy services and individual and societal performance indicators (electricity savings, CO 2 emissions savings, social welfare, consumers' comfort change), as well as consumers' satisfaction. From these results and based on expert validation, we conclude that providing the consumer with more options does not necessarily lead to higher consumer's satisfaction, or better societal performance. A good policy should be centred on e ective ways to tackle consumers concerns.
Nearly twenty-five years ago, the internet disrupted the world and started a new era of technological supremacy. Today, with the rise of cryptocurrencies and its underlying technology we stand at the helm of another such revolution. Cryptocurrencies like bitcoin are peer-to-peer decentralized systems of digital currencies which operate without the need for a third-party intermediary like RBI. Coupled with lack of regulatory guidance, its unique technical aspects create huge complications in its taxation. While much ignorance still prevails in respect of cryptocurrencies, countries around the world have finally started taking notice and act upon it. This paper overviews the complete landscape of taxation of bitcoin-like cryptocurrencies. In this paper, an attempt is made to explain the indirect as well as direct tax structure concern cryptocurrencies, particularly after the implementation of Goods and Service Tax Act, 2017. The paper explains what bitcoins are, why are they important and whether it is necessary for the Government to regulate it. In addition, it discusses the prevailing regulatory structure as well as issues concerning evasionary practices in digital currencies. The findings help assess regulatory aspects in light of technological, economic, social and financial forces and establishes a set framework for taxation of cryptocurrencies.
Incidents of ransomware have been escalating, which could be fueled in part by the diffusion of crypto-currencies. Without crypto-currencies, the creation of ransomware is less desirable because other forms of payment are more traceable. The risk from ransomware can be considerable, and some companies hold supplies of bitcoins in reserve to pay extortionists if necessary. Here, the authors examine crypto-currencies’ effects on ransomware and look at what might influence a victim’s decision to pay.
Trading securities is a process that requires multiple trusted intermediaries to ensure that the trade is done correctly. The securities industry is therefore very slow and expensive; the central securities depository (CSD) being one of the main contributors to the disruption. In an effort to fix this, financial institutions has recently started looking into the blockchain technology; the innovation behind the cryptocurrency Bitcoin. Bitcoin is a digital currency that can be traded peer-to-peer without the need for a trusted intermediary. If this concept could be used when trading securities it would simplify the process, making the settlement-time near instant. In addition to the speedup, it would also save the industry a lot of money since many processes could be automated. The purpose of this paper is to provide an overview of the blockchain technology and its applications in the finance industry. The focus is on how a blockchain could be used to reduce the responsibility of the central securities depository as much as possible, and especially on how corporate actions could be automated. The goal is to answer these questions: Is blockchain a suitable platform for a decentralized corporate actions solution? Whatare the benefits and drawbacks of using a blockchain versus a traditional centralized solution? The aim is to provide an evaluation of the usage of blockchains in finance, with extra focus on the CSD and corporate actions
An increased scientific interest in studying different models of education management systems is conditioned by the fact that the quality of education depends significantly on the management style. Thus, the process of creation of efficient systems of management and financing of the education presents a priority in educational policies of contemporary societies. The paper analyses different approaches to the education management systems in some European countries, on the comparative basis, with the aim of achieving as much of a total insight into contemporary courses of such processes as possible. The results of analysis show that the traditional division into centralized and decentralized systems of management is relativized, with a tendency to achieve an optimal relationship among different subjects in the process of management on the central, regional and local level of authority.
The purpose of this paper is to provide a brief explanation regarding the authors’ current research in the field of the possible uses of smart contracts in cybercrime, focusing in particular on how the technology could provide a substitute for trust both in client-criminal transactions and in transactions taking place within criminal organizations. The authors share the conviction put forward by Alharby and Moorsel [1] in their 2017 analysis of blockchainbased smart contracts that there is a ”lack of studies on criminal activities in smart contracts”: while quality research does exist, including a paper by Juels et al. [2] detailing three types of such activities that can be facilitated by the technology, it is evident that the subject deserves a more widespread attention. Quality research, in fact, could play an important role in aiding authorities and regulators to understand the issue and react accordingly.
