Abstract.As soon as the usage of cryptocurrency in the last few years has been gaining popularity all over the world, and this global trend has affected Ukraine, the purpose of the paper is to examine the essence of cryptocurrency, to identify the issues of its legal regulation in Ukraine, as well as using the analysis of world experience in this sphere, to identify ways of the improvement for relevant domestic legislation. The authors have indicated that the cryptocurrency market (or "virtual" money) operates successfully and provides an opportunity to analyse dynamics of the cost, supply, and demand of about 90-100 different cryptocurrency. Problem's setting. The authors of the paper have emphasized that despite increasing popularity of cryptocurrency in Ukraine and throughout the world, there is no single clear definition of this concept. Therefore, the authors of this article state that cryptocurrency is a digital decentralized currency, a unit of which is a coin cryptographically protected against tampering since it is encrypted information that cannot be copied, while all information about transactions is stored in the blockchain system. Methodology. The study primarily uses comparative methods for the purposes of examination of the approaches taken under different jurisdictions towards cryptocurrency. Additionally, analysis of the body of theoretical literature on the matter was conducted. Results of the study allowed drawing several conclusions on the prospects of further development of the legal framework for cryptocurrencies in Ukraine since nowadays the country is neutral in the issue of using and regulating cryptocurrency and consequently it is losing precious time, because: first, potentially loses money, which could enter the state budget from individuals, who receive income from transactions on cryptocurrency markets; and secondly, the state runs a risk of citizens' rights violation because of no real instruments for their protection. Practical implications of these are proposals to adopt certain amendments to the current legislation in this sphere, including setting up control over brokerage of cryptocurrency, licensing of the industry, and legal definition of the cryptocurrency for the purposes of taxation, etc. Value/originality. The paper represents one of the first comprehensive studies of the current state and prospects of development of the legal framework for the cryptocurrency in Ukraine. Its conclusions provide both proposals for the development of legislation in this sphere and may serve as a basis for the future studies of this topic.

Today, the successful competition of any domestic enterprise in the market of goods and services is conditioned on the use of new technologies and production processes. Such activity is innovative and plays a leading role in its life. Exacerbation of competition and decrease of competitiveness of domestic enterprises necessitate their innovative development. Information, intelligence, knowledge and innovation, which are the backbone of the country's human resources, are of particular importance in this context today. Therefore, the driving factors in the way of formation of personnel component of innovative development of the state economy are the training of innovative personnel – skilled workers, capable of creative work, professional development, introduction of high-tech technologies on the basis of development of the system of lifelong learning. The issues of professional development of employees are becoming especially relevant in the context of globalization, as well as the European and innovative integration of Ukraine. The author investigates the peculiarities of transformations of modern theoretical and legal approaches to professional development of employees in the context of European integration, human-centered and innovative approaches to doing business, in particular, the following tasks are solved: (1) the essence of the concepts of ‘professional development’, ‘functions of professional development of employees’, ‘professional training’ as legal categories is revealed; (2) leading functions of professional development of employees are generalized; (3) the vectors for further reform of the legal regulation of professional development of employees are determined; (4) the prospects and problems of influence of professional development of employees on the innovative development of individual enterprise and Ukraine as a whole are established. The author substantiates that the professional development of employees produces its direct impact both on individual enterprises and on the state as a whole in the sphere of innovative transformations. Undoubtedly, the gradual introduction of European standards and requirements, the adaptation of foreign legal regulation to the domestic realities and features of the legal system will allow to increase the economic potential, innovative component and competitiveness of Ukraine in the world market, as well as to bring the prospects of gradual accession into the European Union.

The study characterizes economic security as a set of conditions that are necessary to ensure the normal economic development of the country and restore the gap in development in comparison with European countries during Ukraine's integration into the EU. It is shown that ensuring economic security is an important function of the state. The problem of economic security arises not only from the definition of the internal policy of the state, but also determines the issues of foreign strategy. The necessity of calculating the main safety criteria has been proved, allowing to anticipate possible dangers, determine potential current and future damage and take preventive measures. Stability and development require a dynamic approach to solving the problem of economic security. This is mainly due to the rapid change in indicators of economic security and indicators with a change in the operating conditions of international, political, economic, market and other systems. The urgency of solving the problems of economic security is based on the need to get rid of the dependence of the national economy on the level of competition in world markets. This is due to the emergence of serious economic risks arising when the actual values ​​of economic security indicators go beyond the threshold levels. The current level of economic security has been investigated by calculating indicators that characterize all sectors of the national economy. The most problematic areas requiring immediate response have been identified. The presented methodology for calculating the integral indicator of the economic security of Ukraine quite accurately describes the current state of the national economy and can be practically applicable to domestic and foreign government bodies in the analysis of critical vulnerabilities of national economic security.

Gender inequality is one of the fundamental manifestations of socio-economic differentiation of the population, leading to different opportunities for self-realisation for women and men in society. This makes it an important topic for analysis even though there may be different views on the matter. The labour market conditions that existed in Ukraine until the end of February 2022 exacerbated the problems of gender inequality in employment. These problems were manifested in unequal opportunities for women and men in public administration, education, employment, income and property. The research uses general and specific scientific methods – dialectical, historical, analysis and synthesis, induction and deduction – to study the legislative frameworks governing gender equality in the European Union (EU) and Ukraine in determining the current state of women’s employment in Ukraine and Europe. In this context, the purpose of this article is to identify the features of gender inequality in the labour market of modern Ukraine, as well as to identify its causes and solutions.

The purpose of the article is to determine the procedural and non-procedural methods of diagnostics false testimony of criminal proceedings participants’, which can be used in the investigation in Ukraine. The authors use general and special methods that allow obtaining scientifically sound conclusions and suggestions. The dialectical method, system-structural, generalizing, logical and statistical methods were used in the study. According to the results of the study, the number of criminal offenses initiated in Ukraine in connection with the provision of false testimony by victims and witnesses is quite large. If a person is convicted based on false testimony, a new criminal trial must be ordered in connection with the newly discovered circumstances. The authors determined that procedural methods of diagnostics false testimony include investigative (search) actions and forensic examinations, and non-procedural - various types of research, in particular, the use of polygraph and physiognomic research, as well as methods of analyzing nonverbal information. Re-interrogation, additional and simultaneous interrogation of previously interrogated persons, investigative experiment are the most effective procedural means of diagnosing false testimony. Non-procedural means of diagnosing false indications require further research and scientific substantiation, including the development of a mechanism for training relevant specialists.
