The paper attempts to analyse the state of the solutions of management organization structures in the public sector, with a particular emphasis on the efficiency of information and decision-making processes determined by correct or incorrectly functioning solutions. The assessment of the functioning of the public administration must be related to the efficiency of the information and decision-making processes and the elimination of inconsistent structural solutions. It is important that the overriding criterion is positively verified solutions and not the political interests of individual parties, which are usually divergent from the substantive assessment criteria. The improvement in decision-making support solutions in the management of local government units was achieved through the formulation of three research hypotheses of the university research team with the municipalities quoted in the work.

In this research, the index of all Croatian cities’ tax autonomy (128) in the 2002-2016 period was calculated. The aim of this research is to show how many Croatian cities control their tax revenues. It is also the goal to determine whether cities have the ability to independently finance local public services to citizens and entrepreneurs. The OECD methodology in the classification of tax revenues was used. The results of the analysis showed that Croatian cities had a relatively low level of tax autonomy, except in the period from 2010 to 2014, when the index of tax autonomy was above 54, while in 2016 it amounted to 41.36. The research results showed that only a small number of cities-without the aid of state government grants-can finance their existing level of public services for residents and entrepreneurs and manage their development. This is an important conclusion in considering the future role of cities in taking over new public functions and increasing the decentralization of public administration and territorial organization of the state.

There are changes that occur in our education which impact on regional competitive build towards a global competitive, both in the formal institutions of national and Islamic institutions. So this raises complex issues that wraps acceleration of development in promoting an Islamic educational institutions in rural areas. These problems include institutional, leadership, finance, personnel, curriculum and educational model. Each of these components can inhibit the saving potential and within certain limits can threaten the existence, sustainability, competitiveness, and progress of Islamic educational institutions. The question of research: how is each of these institutions are trying to attract views of rural communities by providing an alternative strategy such as the advantages and characteristics of the institution in the decentralization and globalization?. This research resulted in four alternative bid that is modeling the Islamic educational institutions business model in the financing strategy, improve excellence at regular intervals sustainable in the interests of rural communities, implement the task of public relations in spreading the advancement of excellence of the school, and no achievement or excellence will find both nationally and internationally. Thus meaning that the top schools are part of a plan to be achieved can run well and there are no gaps in it and is able to work by well.

The article considers the legal framework for the use of smart contracts in Ukraine to assess the prospects for their use in contract law in the context of the digital transformation of the economy. A study of scientific views on the legal nature of a smart contract is presented. The features of blockchain technology, which predetermine the features of smart contracts and the specifics of their application, are considered. The definition of the place of a smart contract in the system of contracts is proposed. The analysis of Ukrainian and foreign legislation in the field of application of digital technologies and smart contracts in the economy was carried out. It has been determined that smart contracts are currently not regulated in the current legislation of Ukraine. Legislation regulating relations related to the use of information technology is just beginning to take shape. It is noted that the lack of internationally coordinated efforts to recognize the legitimacy of smart contracts can be a serious problem. It is concluded that a smart contract is an agreement that can be automated and enforced. This analysis will lead to a critical examination of whether the functionality of traditional contracts has been superseded by the emergence of smart contracts. It is noted that a smart contract is a combination of technological and legal aspects. As a result of the study, problems were identified, the solution of which at the legislative level will allow the introduction of smart contracts in various areas of economic activity. An important characteristic of these contracts is emphasized - automaticity and the possibility of enforcement. The imperfection of legal instruments for regulating the conclusion and execution of smart contracts is noted. It is concluded that a smart contract, taking into account its features, is a contractual structure and that the successful development of smart contracts requires legislative consolidation of the legal status of smart contracts, the parties to smart contracts, the procedure for organizing the protection of the interests of each side of the smart contract.

The accounting profession has long occupied a role and fiduciary responsibility aligned with fraud prevention and safeguarding consumer data and finances. As cryptocurrencies become more prominent and widespread, including utilization by both individual consumers and organizations, the risk of unethical actors entering the market continues to rise. This research approaches the situation from two angles. First, a review of cryptocurrency and blockchain technology, including an overview of the initial coin offering (ICO) process is conducted, including regulatory updates in the space. Second, and important for both academic and practitioner end users of this research, a checklist, guide, and items to consider to assist in preventing fraud connected to cryptocurrencies will be provided.

The aim of the article is to study the theoretical and legal possibilities of using cryptocurrency in purchase and sale contracts, to determine the specificities of such a phenomenon as cryptocurrency (Bitcoin) from the perspective of jurisprudence, and to draw attention of legal scholars primarily to possible further scientific researches on the introduction of this phenomenon in the modern civilian legislation of Ukraine. The subject of the study is the specificities of using cryptocurrency in contracts of purchase and sale. Methodology. The research is based on an analysis of legal acts on the legal regulation of cryptocurrency in Ukraine. By means of the comparative legal method of investigation of certain provisions of Ukrainian legislation, the possibilities and limits of the use of cryptocurrency in contractual relations, in particular, contracts of purchase and sale are determined. The results of the study revealed that the cryptocurrency regime in Ukraine and in many countries is in a legal vacuum. Such a conclusion is based on the lack of clear legal clarification and consolidation of the concept and types of cryptocurrency in the relevant rules of the tax, banking, civil, and commercial law. In case of eliminating this gap, it is advisable to review the state policy on Bitcoin and its analogues. Practical implications. It is necessary and appropriate to introduce a corresponding license for cryptocurrency activities that can minimize the laundering of proceeds from crime or terrorism financing. It is suggested that eventually the relations concerning the digital currency will be regulated in Ukraine, but most likely, it will copy the experience of another state, which may have negative consequences. Relevance/originality. Analysis of a possible use of cryptocurrency in contracts of purchase and sale can become the basis for the development of the most promising directions of domestic civil law in contractual relations.

Many cryptocurrencies rely on Blockchain for its operation. Blockchain serves as a public ledger where all the completed transactions can be looked up. To place transactions in the Blockchain, a mining operation must be performed. However, due to a limited mining capacity, the transaction confirmation time is increasing. To mitigate this problem many ideas have been proposed, but they all come with own challenges. We propose a novel parallel mining method that can adjust the mining capacity dynamically depending on the congestion level. It does not require an increase in the block size or a reduction of the block confirmation time. The proposed scheme can increase the number of parallel blockchains when the mining congestion is experienced, which is especially effective under DDoS attack situation. We describe how and when the Blockchain is split or merged, how to solve the imbalanced mining problem, and how to adjust the difficulty levels and rewards. We then show the simulation results comparing the performance of binary blockchain and the traditional single blockchain.

Compared to gold, cash and commercial bank money, bitcoin is presented as a medium of exchange, functionally similar to electronic money. Bitcoin is known as decentralized, convertible, deflationary and unstable cryptocurrency, deprived of state control and protection. Equally important is the open and global Bitcoin computer network for online transactions, operating without the need for until recently unavoidable intermediaries and different from traditional payment systems. The field of application of virtual currencies is determined by their unusual characteristics, but also by diverse comparative legal regime. Initially as a material for criminal courts and tax authorities, virtual currencies and crypto-subjects are now defined at the EU directives level. Contractual relationships and financial obligations take new forms in crypto-environment, so the question arises: to which extent a positive law is able to absorb until recently improbable concepts. The privacy and freedom that cryptocurrencies bring has its own backwardness, and the legal order is over focused on that side of a coin. On the other hand, the risks in private law transactions involving bitcoins remain unresolved, although legal subjects need this kind of legal protection badly.

The main aim of this paper is to examine interdependencies between prices of cryptocurrencies, with the special focus on Bitcoin. The analysis is conducted in two stages and results are compared between two consequent sub-periods. In order to analyze topological properties of cryptocurrency market, the Minimum-Spanning Tree technique is used. Results indicate that Bitcoin plays one of the most important roles in the cryptocurrency market, while other cryptocurrencies form clusters and such forming has a sensible economic interpretation. In the second stage, main cryptocurrencies from each of formed clusters are analyzed using the Vector Autoregression methodology. The results from VAR (1) indicate that demand shocks in Bitcoin price are not contagious to other cryptocurrencies, while some interdependencies within the formed clusters may be observed. Overall, results indicate that conclusions drawn from the analysis of Bitcoin shall not be generalized to the entire cryptocurrency market.

ABSTRACT Darknet markets (DNM) and bitcoins are two emergent topics in the information field and have attracted much attention. However, few has explored them together. This study aims at understanding the relation between them. It is investigated that whether the bitcoin exchange value and the public interest in it are predictable of the daily sales in the darknet markets in the future. By applying the Granger‐causality analysis, we find that the daily bitcoin exchange value with one day lag are Granger causative of the sales, so does the daily searching frequency in Google with one, two, and three‐day(s) lags. From the linear regressions, we find that the increasing bitcoin price reduces the daily DNM sales, while the increasing public interest in bitcoins facilitate the sales. By understanding relation between the DNM sales and bitcoins, two emergent topics in information science, we can get some insights on how to monitor the activities in the DNM, especially those illegal transactions and can further extend to how to regulate the DNM.

Bitcoin is a type of cryptocurrency that implemented decentralized digital currency method. The transaction is monitored and validated by peer-to peer system using hash programming. These transactions are verified by network nodes through the use of cryptography and recorded in a public distributed ledger called a blockchain. The objective of this study is to forecast the Bitcoin exchange rate using weighted moving average method. Data selected in this study are selected hourly from 14 th December 2017 until 18 th December 2017. The forecasting method is using weighted moving average. Then, the validity of the forecasting model is validated using mean absolute percentage error (MAPE) calculation. Results indicated mean absolute percentage error is 0.72%. Therefore, the moving average method is considered as reliable forecasting method for Bitcoin exchange rate. The finding of this study will help investors to make best decision regarding suitable portfolio for their investment.
