Blockchain is a new technical innovation based on distributed ledger technology, which, according to the literature, promises to improve supply chains by facilitating trusted transactions. Due to its immutability it can help eliminate third parties, which traditionally intermediate between the parties involved in transactions. Large multinational companies that have major influence in supply chains can easily rape the benefits of blockchain, however, small and medium size enterprises (SMEs), which together generate 99% of the added value of the Dutch economics, do not have the means to achieve this. Therefore, this research poses the question, which user cases exist already and which opportunities do they offer for SME's to create value. The paper answers this question based on literature and the analysis of 70 user cases. Based on the analysis the SMEs are advised, which of the following five strategies to follow, ignoring it, waiting to see the market developments, make use of blockchain services offered by the new blockchain based middlemen, such as the supply chain finance, paperless and market platform solutions, integrate in existing blockchains of multinationals as Maersk or create their own blockchain.

The article reviews the peculiarities of cryptocurrency circulation in the world and domestic financial systems. It is determined that scientific researches of the recent years are devoted to the specifics of cryptocurrency, the risks associated with the circulation of cryptocurrency and government instruments for their minimization. The general risks associated with the circulation of cryptocurrency, including the possibility of its use for the legalization of criminal proceeds. The peculiarities of the policy of the USA, Singapore, Argentina, Canada, the Czech Republic, and China in the direction of minimization the risk of legalization of incomes through cryptocurrency, in particular, criminalization of fraud with digital currency, restrictions on operations with cryptocurrency are revealed. Particular attention is paid to the experience of Ukraine in the field of legal regulation of cryptocurrency circulation. It is concluded that the key for minimizing the risk of money laundering through cryptocurrencies is the lack of a generally accepted cryptocurrency status, given that its definition is a priority in the direction of safe circulation of cryptocurrency in the world and domestic financial systems.
Development of information technologies, cryptocurrencies and technology of distributed networks has caused the appearance of smart con- tracts as new types of civil contract. They have been widely used in recent years in such areas as initial coins offering (ICO), financial sector, inter- national trade and public services. At the same time the legal status and legal regulation of smart contracts are uncertain. These uncertainties cause many legal risks of smart-contractsutilization. The purpose of this article is to find out the conception of smart contract as a form of civil contract, to research its legal status and legal regula- tion issues and to develop proposals for the improvement of legal regulation of smart contracts and cryptocurrencies in Ukraine. By its legal nature a smart contract is a digital form of a civil contract realized in programming code automatically executed in a distributed network. Like a civil contract, smart contract has such elements as parties, subject and essential terms of the contract. The legal force of a smart contract depends on whether it includes the fundamental features of a civil contact, such as evidence that parties have intention to create legal relations, understandabil- ity of contract conditions and possibility to perform the terms of the contract under duress. The main advantages of a smart contract are its ability to significantly accelerate and reduce costs of the transaction and guarantee the fulfillment of contract terms regardless of the contractual parties' and third parties' will. The main risks of a smart contract are uncertainty of legal status of a smart contract and cryptocurrencies as a means of payment, complexity of expressing the contact terms in a mathematical algorithm, risk of software bugs and hacking attack. To solve the problems of legal regulation of smart contracts in Ukraine it is necessary to change the legislation in order to settle the legal status of cryptocurrencies and recognize a smart contract as a form of a civil contract. It is necessary to identify parties of the smart contract, confirm their agreement on the terms of the smart contract by using digital electronic signature. A smart contract should be supplemented by text application containing the es- sential terms of the contract which will have legal force in trail. It is necessary to implement blockchain technology in the state registers and pro- vide legal ability to make adjustments in the registers automatically for the performance of smartcontracts.

Аргументовано різний підхід ЄС до правового статусу криптовалют – одні країни визнали доцільність їх використання та працюють над створенням законодавчої бази, яка закріплює правовий статус віртуальних валют, а інші країни відмовляються від криптовалют та забороняють їх обіг. Пропонувалося розробити окремий законопроект із залученням активної частини криптовалютної спільноти, який містив би положення про визначення криптовалюти як валюти, відмову від бартерного характеру криптовалюти, встановлення Національного банку України як головного регулятора таких відносин, відмова від обмеження придбання криптовалюти лише в спеціалізованих фінансових регуляторах через можливі корупційні ризики, встановлення порядку ліцензування та проведення процедур AML та KYC, прогнозування реальних практичних кроків щодо запровадження пільгової системи оподаткування видобутку корисних копалин з подальшим внесенням змін до податкового законодавства.

The article discusses the issues of the legal control of cryptocurrency in the system of civil rights under Ukrainian law and bills submitted to the Parliament of Ukraine. It is proved that the emergence of cryptocurrency in developed countries is an evolutionary stage of the cash form. This requires changes in the legislation of legal and tax control, which are able to form a protective mechanism against cybercrime and fraud in the field of cryptocurrency circulation. The possibility of evaluating cryptocurrency as electronic means, currency values, information, money, intellectual law and other property is being considered. The risks of possible fraud of transactions with cryptocurrency as the consequences of unregulated legislation were analyzed. The prospects of the settlement of cryptocurrency circulation in Ukraine were considered.
Использование криптовалют в международной практике говорит о том, что страны отличаются ее реализацией в обращении. Это объясняется, прежде всего, новизной этого инструмента и отсутствием единого определения категории «Криптология», которое бы раскрыло его суть. Положительное отношение к биткойнов характерно для развитых стран, а в развивающихся странах, есть некоторые ограничения в этой области. Также появление нового товара на рынке инновационных технологий привело к появлению нового объекта учета - электронных денег.
Поэтому страны на глобальном уровне должны регулировать систему налогообложения операций с криптовалютой; ввести методику ведения учета операций с ними для дальнейшего развития предприятий и их интеграции в глобальную экономическую среду.
У статті на основі аналізу причин стрімкого падіння цінності криптовалют у 2018 р. і особливостей 17 альткоїнів з найбільшою ринковою капіталізацією зроблено висновки про вектори розвитку криптовалют і перспективи цього феномену. Виявлено вектори розвитку криптовалют: 1) валюти платформ для створення і функціонування децентралізованих додатків (Ethereum та альтернативні платформи: Eos (позиціонується як швидша, простіша, дешевша); Cardano (для фінансових додатків, що використовуються у щоденній діяльності); Neo (валюта платформи, дружньої до регуляторів (зокрема, китайських); Ehereum Classic – більш децентралізована, з більш строгою незворотністю транзакцій, ніж у Ethereum); 2) платформи для більш ефективних транскордонних платежів (Ripple та більш децентралізована альтернатива – Stellar); 3) вирішення технічних проблем біткоїна (Litecoin – більш зручна для дрібних трансакцій, Bitcoin Cash – альтернативне вирішення проблеми масштабування трансакцій); 4) полегшення торгівлі криптовалютами і вирішення проблеми їхньої волатильності – Tether; 5) внутрішні валюти криптовалютних бірж (Binance Coin); 6) збільшення анонімності трансакцій: Monero, Dash; 7) забезпечення транзакцій в Інтернеті Речей – IOTA; 8) універсальна валюта для віртуальних розваг – TRON. Обґрунтовано гіпотезу, що, не впоравшись з амбітною роллю альтернативи суверенним грошам ієрархічної природи, криптовалюти частково зійдуть до ролі віртуальних валют для локальних віртуальних просторів, а частково перенесуть частину своїх властивостей у традиційні платіжні системи, аби полегшити, скажімо, транскордонні транзакції. Загалом, процес поширення криптовалют синхронізується з процесом поширення інформаційно-мережевої економіки.

Introduction. Due to the rapid development of computer technology, their active implementation in all spheres of life, people began to solve everyday problems much faster. IT-technology is one of the most relevant branches of science at the modern stage of development of society, because today every company keeps records of its activities using computers. \n \nThus, in the future, the accounting sector is expected to undergo major changes, because the technology “Вlockchain” is actively implemented in the financial sector of the country. The investigated platform has an important property for accounting work, because the information created in this database can be trusted, even if there is no trust in the counterparty. The transaction is carried out only if it is approved by both parties. \n \nPurpose. The purpose of the article is to substantiate the feasibility of implementing Blockchain technology in accounting. \n \nResults. Proponents of technology believe that the new tool will be able to replace not only accountants, but also banking institutions and many financial intermediaries. According to the Blockchain Research Institute, Ukraine is included in the list of 14 countries which were recognized as leaders in the implementation of Blockchain. However, the state has to restructure huge systems with a large number of people to use this tool. It is also necessary to prepare legislation properly and take into account the fact that high energy costs are needed to support technology. \n \nThe technology aims to put an end to the traditional methods of invoicing, documentation, processing, registration, inventory systems and business payment. Вlockchain allows companies to record both sides of the transaction simultaneously in a shared workbook in real time and not store the reconciled entries of financial transactions in separate private created databases y or for the account books. The need for traditional double-entry accounting will be eliminated, as the verification of the legality of accounting will be fully automated. \n \nConclusions. Directions of use of technology in accounting require, first of all, proper preparation of legislation. Taking into account the prospects of using this tool, we can assume that the Blockchain will be used in Ukraine in 10-15 years and only when the national legislation is adapted to the new realities of the use of information technologies.

The subject matter of the article is the substantiation of the problems and perspectives of the introduction of Distributed Ledger Technologies (DLT) / Blockchain in the public and private sectors as a modern digital economy instrument. The goal of the work is to substantiate the scientific and methodical principles of implementing the technologies of distributed DLT / Blockchain registers. The following tasks were solved in the article: the notion of Distributed Ledger Technologies (DLT) and Blockchain is defined; types of Distributed DLT Registries are presented in the form of a classification with a distinction of features and possibilities of application of each type; the general scheme of work is described and the specific features of the Blockchain technology are systematized;the features and directions of the use of intelligent contracts (smart contracts) based on the technology of blockchain are singled out;the international experience of government initiatives and pilot projects of the blockade technology application has been analyzed; the analysis of the domestic experience of practical application of Blockchain technologies in the public and private sectors and the perspective areas for the future application of technologies of the distributed DLT registries are identified; according to the international analytical agencies research results, the obstacles of the Blockchain technologies implementation in the public and private sectors are systematized. The following methods are used: abstract-logical analysis, theoretical generalization, system and statistical analysis. The following results were obtained. The concept of technologies of distributed DLT / Blockchain registries is disclosed. The availability of the system is based on open, private and federal DLTs. The specific features of DLT / Blockchain distributed registry technologies include centralization, involvement of a large number of participants to achieve consensus, use of cryptography and digital signatures, almost impossible to change chronological records, the convenience of tracking and verifying information, and the ability to program. The international experience of using Blockchain technology in countries such as the Great Britain, Georgia, Estonia, the USA, the United Arab Emirates, Italy has been researched. Examples of practical implementation of DLT / Blockchain registry technology in Ukraine are considered. The main obstacles to implementing distributed DLT / Blockchain registries in the public sector are regulatory restrictions and technology immaturity. The obstacles to the introduction of block technologies in the private sector are identified. Conclusions: It is proved that the distributed DLT registry technology has a significant potential for development for the future digital economy. Nevertheless, there are a number of barriers to their full use in the public and private sector, which requires further study by experts.

The article is devoted to the discussion of actual problems of introduction of blockchain technology in banking business, the solution of which determines the prospects of wide commercialization of these innovations. Commercial banks' interest in innovation is determined by the threat of steadily declining business profitability and a new competitive threat to traditional sources of income from new fin-technologies. Despite the active development of crypto-innovations (algorithms, platforms, crypto-currencies), the use of blockchain by banks in the financial sector is still very modest. Like most of the participants in this market, banks only carefully test computer technologies for managing a distributed ledger, and therefore objective barriers hindering progress in this area are of actual interest to specialists and researchers. The application of any innovative technology in the banking business depends on the successful compliance of new opportunities and time-tested requirements of consumers in the financial sector. In particular for the technology of the blockchain, just has not fully resolved key-problems of standardization, boundary identification, security and cyber-security, reliability of execution transaction, scalability of projects, etc. Here considered the main barriers, from the author's viewpoint, of implementation of the blockchain in the banking business, confirmed by the authoritative materials of centers for innovative financial technology.

The need to obtain prompt access to funds through electronic communications, protecting investment after the global financial crisis has led to the emergence of a new type of electronic money — the cryptocurrencies. The modern state and prospects for development of the cryptocurrency as a special kind of electronic money were expounded. Cryptocurrencies gain significant popularity due to the advantages of their use, such as: comfort, independence, accessibility, lack of engagement, confidentiality, no documents, full automation of accounting, and cost optimization for administration. Various scientific positions concerning the accounting and economic positioning of the cryptocurrencies in Ukraine were researched. The proposed order to display in accounting the processes of initial obtaining (mining) with the definition of a cost calculating method and operation of the cryptocurrencies most fully corresponds to the national accounting treatment. It was proposed to resolve to the problems of management accounting of electronic money and cryptocurrencies in Ukraine through the combination of functional capabilities of the blockchain technology, positive qualities of the «Internet Bank» and «Client-Bank» communications, which will enable to create a hybrid system of non-cash payments by the cryptocurrencies, electronic money, funds on accounts in a bank with free conversion of existing funds and possibilities for information exchange with all the participants in settlement operations. The article presents a methodology for collecting accounting information on settlements with the cryptocurrencies and other electronic money without the formation of traditional payment documents and bank statements. Electronic information from the hybrid communication system is the foundation for fully automated documenting, formation of accounting records, informing accountants and management of non-cash transfers. Automation of management accounting of electronic transactions helps to increase the level of internal and external control over execution of money operations due to timely and remote informing sharing about the parameters of payments.

The current article examines the peculiarities and legal nature of Bitcoin, Lifecoin, Namecoin, Quark, WebMoney, Ripple and other virtual currencies. There is no single understanding of the legal essence of virtual currency in the world today; therefore, the legal status of such currencies is not officially fixed and there are no official rates of Bitcoins or other crypto currencies against national currencies. Their rate is determined in the course of trading at virtual Bitcoin exchanges and exchange platforms. Such a situation is dictated by the novelty of legal relations in the field of crypto currency circulation, the risks of their implementation, as well as security problems. The main goal of the study is to define the legal nature and features of virtual currencies and the possibilities of legislative regulation of using crypto currencies. When writing the article, the methods of collecting and studying singularities have been used, as well as generalization methods, the methods of scientific abstraction, and the methods of studying regularities. The study has concluded that it is advisable to provide for the licensing of mining and crypto trading at the international level, customers should be identified when selling and buying virtual currencies, introducing a special verification procedure for Bitcoin users will prevent the abuse of virtual currencies for money laundering and terrorism financing. As a result of the analysis, a definition has been given, and the main features and functions of the virtual currency have been highlighted. It has been proved that virtual currencies are a new kind of electronic money stored in computer memory, the monetary value of the virtual currency is managed by means of a technical device. Virtual currency is a new means of payment and does not require access to deposit accounts.
Cryptocurrencies – a new, but quickly developing concept within the sphere of finance. Opinions regarding it still differ, not only on a personal level, but also when it comes to governments. Overall the legal regulation regarding cryptocurrencies in the world is still in the formation stage. Currently the legal norms that do exist, are primarily directed towards the minimization of existing risks, especially in the field of money laundering. Though there is already no reason to doubt, that during the coming years the regulation will become stricter. In some countries cryptocurrencies are outright forbidden. For example, in China, in February 2018 additions to the legislation were issues, that broadened the cryptocurrencies ban. In other countries cryptocurrencies shall be strictly regulated. For example, in Estonia, a member of EU, cryptocurrencies are fully legal. Estonia can be reviewed as a country that independently developed its own regulation in this field. Though there is no guarantee that the legislators will keep up with the quickly developing technologies. One way or another cryptocurrencies exist and are not going anywhere. The legislation that regulates them shall be developed further and they shall become a important part of the modern financial system. The level of their influence is hard to predict, things are changing too quickly, but their existence is a fact. It is necessary to remember, that that cryptocurrencies are not a magical solution or means of profit. It is a financial instrument, new, in many ways unique, with its own special drawbacks and benefits. It is important to know and understand them, also to keep an eye on the developing technologies.
The current global financial market is witnessing the activation of cryptocurrency as a payment instrument and a means of accumulation. However, the risks of money laundering, terrorism financing and tax evasion that cryptocurrency transactions imply lead to the need to implement their state regulation, an important component of which is tax control.Therefore, the purpose of the article is to substantiate the value orientations when forming the system of cryptocurrency transactions tax control in Ukraine taking the positive experience of developed countries into account. The scientific results of the study consist in the emphasizing structural, functional, systemic and institutional approaches to understanding tax control, which became the basis for identifying the features of cryptocurrency transactions as a tax control object.It was revealed that the lack of personalization of the agreement parties, the relatively high level of information security, free international turnover and a decentralized payment system are the factors of the cryptocurrency market further development. On the other hand, this leads to the loss of tax revenues for Ukrainian budgetary system, taking into account the forecasted trends in the development of the cryptocurrency market by 2022 through methods of sums, least squares and expert estimates. Given the institutional approach to the understanding of tax control, an institutional structure of the cryptocurrency transactions tax control in Ukraine is proposed.It is established that domestic state institutions are able to carry out tax control over these transactions. It is also determined that introducing fiscal control will result in the receipt of additional revenues by budgets, reduction of shadow economy, counteraction to cybercrime and terrorism financing.The practical importance of the results is in the need to form an effective system of cryptocurrency transactions tax control as a function of public administration.It has been determined that transactions on cryptocurrency supply, on the determining exchange rates and transactions on cryptocurrency disposal should be an object of tax control in Ukraine. Mining transactions, receipt of income (profits) in the cryptocurrency are subject to general taxes, depending on the taxpayer’s legal status, in particular, personal income tax, corporate income tax and a unified social tax (UST). Taking into account the EU recommendations on the non-application of value added tax in the cryptocurrency transactions taxation, it is not appropriate to implement it in this area. Establishing tax control over cryptocurrency transactions will expand the powers of state authorities that are empowered to control observing financial discipline by economic agents in Ukraine and the financial capabilities of state and local budgets.
The article deals with the problems and prospects of blockchain implementation as a general purpose technology in the financial sector. The underlying mechanism of this technology is described, practical cases of its adoption in various segments of the financial sector and in the field of corporate governance are provided. Cryptocurrencies’ status, issuance and regulation are also discussed.
The purpose of this article is to determine how the use of a bitcoin as an instrument of payment can affect the system of international financial payments and the banking system. The method of critical analysis of scientific and methodological literature is used and the materials of research executed by leading experts in the fields of international finance and IT in 2009-2017 are summarized. A bitcoin can become a serious competitor to banks, payment systems such as SWIFT in the implementation of major cross-border payments. It is even compared with gold because there is no risk for the counterparty in operations with it. We suggest that a bitcoin is an outstanding digital technology which can fundamentally change the world banking system, payment settlements and the global economy. The article proposes a classification of advantages, disadvantages and prospects of using a bitcoin as a means of payment between large financial institutions and banks. The perspective of increased competition between leading international payment systems in conducting large cross-border payments is substantiated. The prospects of further studies are determined. How do central banks need to reform the system of international financial payments in view of the inevitable introduction of cryptocurrency? How to implement new financial instruments based on blockchain technology and a bitcoin? What changes in legislation should be made to get the names of buyers and sellers of bitcoins, which will help to reduce financing of illegal activities?
In Ukraine, the cryptocurrency is viewed as a monetary surrogate. In many countries of the world, operations with cryptocurrency are more or less permitted. You can name countries such as Australia, Austria, Bulgaria, Brazil, Israel, Canada, China, Norway, Singapore, USA, Thailand, Germany, Croatia, Switzerland, Japan and others. On the basis of objective analysis and the study of examples from foreign experience, the legal regime of operations with the cryptocurrency is proposed to equalize with the legal regime of operations with foreign currency; legalize the mining of the cryptocurrency as a type of economic activity, introduce its licensing and taxation of income from it. Citizens of Ukraine are not forbidden to keep savings in foreign currency and exchange foreign currency for hryvnia and other foreign currency. Ukrainians can not receive wages or any remuneration in foreign currency on the territory of Ukraine, but they can earn or win foreign currency on the Internet. The same regime should receive cryptocurrency. And operations on mining of cryptocurrency should be licensed as highly profitable and requiring a special knowledge and skills type of economic activity. Applying income tax to miners is offered on general terms. Three ways of determining the amount of taxes are proposed: 1) granting access to representatives of the fiscal body to the computer program and purses of the cryptocurrency; 2) through the calculation by the representatives of the fiscal body of the average monthly volume of production of units of crypto currency for a certain equipment and, accordingly, in proportion to it, the amount of tax; 3) in proportion to the amount of electricity spent. The last two look the most real. In the case of taxation of operations on «mining» of cryptocurrencies, the state through the amount of electricity consumed can identify and control miners. It is concluded that the legalization of the state of the budget. REFERENCES Derevianko B.V.

The development of information technologies is accelerated in the modern world. The digitization of socio-economic relations is carried out on the basis of peer-to-peer blockchain technology. Bitcoin is a cryptographic protocol. The article shows that, to date, there is no common understanding of Cryptocurrency, in some sources they are treated as currency and other goods or raw materials in other. At this moment, cryptocurrency in Ukraine is not regulated at all. This article discusses the potential legal classification of Bitcoin and the consequences thereto. Bitcoin has been, and continues to be, used by some for the purchase of illegal substances and in furtherance of crimes. Nonetheless, Bitcoin possesses significant economic upside over traditional currencies and methods of transaction online. The National Bank of Ukraine (NBU) has not yet recognized bitcoin or other encrypted currencies. Several bills to regulate encrypted money have been submitted, but none has yet been passed. The Ukrainian parliament has been actively trying to find a solution for creating a legislative and regulatory framework specific to the cryptocurrency industry. Ukrainian draft laws give their own definition of crypto-currency, mining and other specific terms; stipulate those who have the right to engage in mining, how the activities of exchanges are regulated, and the attendant moments, such as legal responsibility and specific taxation. Yet, the proposed legislation has not yet been passed into the law. Ukraine should monitor world trends and not miss a chance to use new technologies and innovations in the financial sector. On the basis of the analysis of domestic and foreign practices, a number of non-regulated by Ukrainian law of the creation and circulation of cryptocurrencies have been identified by the law of Ukraine, proposed ways of resolving issues of determining their legal nature and legal regulation. The situation regarding the definition of legal status of cryptographic goods in foreign countries and Ukraine is analyzed. The main points to be solved in the course of approval of the right regulation of cryptocurrencies in Ukraine are determined. REFERENCES Liashenko V.I., Vyshnevskyi O.S.

In preparation for improving the consortium blockchain’s performance for financial business applications, the current authors first surveyed typical records of transaction rates for various financial systems and the performance capacity of several known consortium blockchains at this moment in time. The blockchain itself does not offer any performance advantage, but rather sacrifices performance to achieve tamper resistance. The average transaction rates for blockchain technologies, however, are continuously improving and have already reached around 1,000–2,000 transactions per second (TPS), which is equivalent to the transaction rate for the Zengin System, the common name for Japanese Banks’ Payment Clearing Network. Next, the current authors analysed and improved the transaction rate for Hyperledger, a Linux Foundation Project, and Fabric, one of the open source software tools for implementing consortium blockchain. The current authors found that inefficient message transfer between the platform container and the application container was the main cause of Fabric’s performance bottleneck. Therefore, the current authors have introduced more efficient application programming interface (API) between the containers and improved the transaction rate from 725 to 1,350 TPS (an 86% increase). Finally, the current authors analysed Fabric’s performance under artificial network latency. This paper determines that Fabric running over a wide area network might be required to replace its consensus algorithm to improve its transaction rate because other causes of performance deterioration, including the consensus algorithm, seem to become dominant.
