The article examines the role of blockchain and financial technologies in ensuring the transparency of operations with virtual assets in the context of the digital transformation of the financial system. It is substantiated that the development of financial technologies is one of the key drivers of the modernization of contemporary financial markets, shaped by global processes of digitalization, innovation, and changes in the economic behavior of market participants. It is determined that financial technologies form a new architecture of the financial system and contribute to increased efficiency, accessibility, and transparency of financial services.The study analyzes global and national factors influencing the development of financial technologies. Among them, particular emphasis is placed on the digitalization of the economy, the advancement of blockchain technologies and decentralized finance, changes in consumer expectations, the globalization of financial markets, as well as institutional, regulatory, and infrastructural challenges at the national level. It is demonstrated that the combination of these factors determines the pace and directions of the implementation of innovative financial solutions, particularly in the sphere of virtual asset circulation.The paper explores the economic essence of virtual assets as digital objects that possess value and operate within a digital environment based on distributed ledger technologies. The main types of virtual assets include cryptocurrencies, tokens, stablecoins, and non-fungible tokens (NFTs). Their economic functions, specific characteristics, and risks associated with high volatility and the cross-border nature of their circulation are systematized.Special attention is paid to the impact of financial technologies on the management of virtual assets. It is substantiated that the use of blockchain platforms, smart contracts, analytical and monitoring financial solutions, digital custodial services, and regulatory instruments contributes to enhancing transparency, accountability, and controllability of operations with virtual assets.The study systematizes practical solutions for ensuring the transparency of operations with virtual assets and identifies their impact on building trust, reducing operational risks, and improving the effectiveness of financial control.It is concluded that the transparency of operations with virtual assets is formed through the comprehensive integration of blockchain and financial technologies into a unified digital financial infrastructure, where the maximum effect is achieved through their combined application. Ensuring transparency in virtual asset operations is systemic in nature and requires the integration of technological, organizational, and regulatory instruments. In this context, blockchain and financial technologies act not only as technical tools for recording transactions but also as key drivers of trust, efficiency, and stability in digital financial markets.The necessity of combining technological, organizational, and regulatory instruments is emphasized, along with maintaining a balance between the transparency of financial operations and the protection of confidential data. Prospects for further research are identified, including the evaluation of the effectiveness of financial technology implementation across different segments of the financial market and the development of regulatory models for the circulation of virtual assets.

Висока волатильність криптовалют та швидке поширення технологій штучного інтелекту (ШІ) у фінансовому секторі визначають необхідність точного прогнозування ризиків і поведінки інвесторів у процесі цифрової трансформації фінансових ринків. Метою дослідження є розробка системи економетричних моделей для оцінки прибутковості, волатильності, ліквідності та ризику падіння основних криптоактивів із використанням методів на основі ШІ. Методологічна структура включає моделі специфікацій ARDL-MIDAS, GARCH-MIDAS, PMG та logit, які поєднують високочастотні ринкові дані, макроекономічні індикатори, он-чейнгові метрики та індекси настроїв інвесторів. Вибірка охоплює вторинні дані за 2018-2025 роки для п'яти провідних активів — Bitcoin, Ethereum, BNB, XRP та Solana. Результати моделі ARDL-MIDAS показали, що збільшення обсягів торгівлі на 1% збільшує короткострокову прибутковість на 0,012 пункту, водночас зростання індексу VIX зменшує їх на 0,014 пункту. У моделі GARCH-MIDAS коефіцієнти α=0.085 та β=0.900 підтверджували високу інерцію волатильності біткоїна, а компонент MIDAS у VIX мав значний вплив 0.27. Модель панелі PMG виявила негативний довгостроковий вплив волатильності на ліквідність (−0,27) і позитивний ефект надпливу стейблкоїнів (−0,12), що вказує на функцію стабілізації. Логіт-модель довела, що збільшення на стандартне відхилення індексу VIX збільшує ризик краху на 52%. Отримані результати підтверджують ефективність поєднання економетричних методів і ШІ для аналізу цифрових фінансових ринків і технологій ШІ для аналізу цифрових фінансових ринків. Висновки підкреслюють можливість практичного застосування запропонованих моделей у фінансовому прогнозуванні, управлінні ризиками та політиці стабілізації цифрових активів у контексті розробки інтелектуальних фінансових систем на основі ШІ.

Introduction. In the process of decentralization of power in Ukraine, the role of local governments in the formation and implementation of information policy has significantly increased. This has opened up new opportunities for ensuring transparency, accountability and public involvement in governance processes. However, at the same time, full-scale war, information threats, uneven institutional development of communities and limited resources have created significant challenges. In modern conditions, effective and transparent information policy is critically important for preserving democratic values, mobilizing public support and ensuring the sustainability of local development. Problem Statement. Despite the formation of legal and strategic foundations of information policy, its implementation in decentralization remains fragmented. Communities have different levels of access to digital tools, human resources and financial resources. The lack of unified transparency standards and monitoring mechanisms leads to a decrease in the effectiveness of communications and an increase in distrust on the part of citizens. The purpose of the article is to identify the challenges and prospects of forming a transparent information policy at the level of territorial communities in Ukraine under decentralization, as well as to develop practical recommendations for improving institutional, legal and digital mechanisms for its implementation. Methods. The study applied methods of analyzing the regulatory framework, comparing information policy models at different levels of government, generalizing practical experience of communities, and predicting the consequences of introducing certain management decisions. Results. The article analyzed the main barriers to forming a transparent information policy under decentralization, including limited digital infrastructure, weak institutional capacity, uneven access to information, and a low level of trust in government bodies. The potential of decentralization for introducing flexible and adaptive information policy models is revealed, in particular through the development of open data, local e-government platforms, and involving the public in the information process. The need to create unified standards of openness, digitalization of information procedures and training of local officials is substantiated. Practical recommendations are proposed for the formation of effective information policy on the ground, based on the principles of transparency, participation and trust. Conclusions. Transparent information policy should become an integral part of the development strategies of territorial communities in the context of decentralization. Its effectiveness depends on an integrated approach that includes regulatory support, financing, digital transformation and human capital development. Public administration should ensure not only the creation of favorable conditions for the implementation of openness policy, but also constant monitoring, feedback from citizens and adaptation to new challenges, including threats to information security in war conditions.

The article examines the economic nature of local finance and determines its social role under the transformation of Ukraine's public finance system. The study analyzes the historical evolution of local finance in foreign and domestic contexts, revealing a transition from viewing it as a simple community expenditure estimate to recognizing it as a complex instrument for territorial viability and financial independence. The research highlights that while foreign models followed a gradual path toward autonomy, the Ukrainian experience was marked by a long period of centralization within an administrative-command system, which is currently being overcome through fiscal decentralization. The paper systematizes academic approaches to defining "local finance" into five categories: system-resource, functional, economic, socio-economic, and legal. This classification demonstrates the multidimensional nature of local finance as both a component of public finance and the foundation of local self-government. The authors propose an updated definition, describing local finance as an institutionally regulated system of economic relations that ensures the implementation of both own and delegated powers, satisfies public needs, and promotes sustainable socio-economic development. Under the conditions of martial law and the challenges of post-war recovery, local finance is shown to transform from a mere budgetary tool into a strategic mechanism for social stability. The study concludes that the modern social role of local finance is centered on supporting internally displaced persons, ensuring security, and facilitating the recovery of territorial communities, thereby serving as a fundamental element of public finance sustainability.

This article develops a methodological approach to the digital transformation of public administration for sports infrastructure at the regional level under the systemic challenges of martial law. The relevance of this research is determined by the necessity to transition from universal digitalisation models to targeted technological solutions capable of addressing specific institutional dysfunctions within the management system. The aim of this article is to substantiate the methodology of targeted digitalisation as an alternative to comprehensive automation of management processes in the sphere of sports infrastructure. The research combines empirical analysis of management practices with theoretical modelling of digital transformation mechanisms, employing the concept of ‘digital levers’ for organisational change adapted from Westerman, Bonnet, and McAfee’s framework.The study identifies systemic dysfunctions in public administration, including fragmentation of the management hierarchy, deficiency of control mechanisms, limited regional absorptive capacity, and institutional barriers to innovation implementation. Through triangulation of budgetary reporting data, audit conclusions from the Accounting Chamber of Ukraine, and technical documentation from the DREAM digital platform, the research reveals a fundamental disconnect between technological capabilities and institutional readiness for transformation. The developed targeted digitalisation matrix establishes a methodological connection between the characteristics of management pathologies and the functional capabilities of digital technologies. This approach differentiates technological interventions according to three criteria: the nature of dysfunction (structural, procedural, behavioural), the level of digital maturity amongst management entities, and existing resource constraints.The principle of ‘problem-oriented digitalisation’ is substantiated, whereby technologies are selected not for their innovative qualities but for their capacity to influence the reproduction mechanisms of specific management dysfunctions. Each digital instrument is mapped to particular pathology reproduction mechanisms: automation reduces subjective factor influence, distributed ledger technology ensures data immutability, machine learning algorithms optimise resource allocation, and IoT networks provide objective infrastructure monitoring. The research demonstrates that whilst platform-based solutions like DREAM represent technological advancement, their effectiveness remains limited without addressing underlying institutional incentives that perpetuate dysfunctional practices.Prospects for implementing distributed ledger technologies are identified for ensuring transparency of financial flows and automating resource allocation through smart contracts. The study proposes a three-tier implementation architecture: cloud-based solutions for frontline territories lacking local infrastructure, hybrid platforms for regions with moderate capacity, and comprehensive smart ecosystems for developed urban centres. The conclusion is drawn that targeted digitalisation ensures systemic transformation of public administration through precise impact on the reproduction mechanisms of institutional pathologies, unlike universal solutions that merely digitise existing inefficient practices. This methodological approach offers particular value for post-conflict reconstruction contexts where resource constraints demand maximum efficiency in technological investments.

The article is devoted to the study of blockchain technologies as an institutional tool for modernizing public administration in the context of the transition to Democracy 3.0. The relevance of the study is determined by the need to find new mechanisms to improve the efficiency, transparency, and legitimacy of public administration in the context of the digital transformation of society. This issue is of particular importance for Ukraine, which is simultaneously modernizing its state institutions in the context of war and European integration processes. The aim of the study is to provide a theoretical and methodological justification for the role of blockchain technologies as an institutional tool for the transformation of public administration in the context of the emergence of Democracy 3.0 and to determine the prospects for their implementation in the Ukrainian public sector. The methodological basis of the study is a neo-institutional approach, which allows us to consider blockchain not only as a technology, but also as a new type of institutional organization that transforms the rules, norms, and mechanisms of interaction between the state and citizens. The main results of the study include the conceptualization of the phenomenon of Democracy 3.0 as a new paradigm of public administration based on the principles of decentralization, transparency, and continuous citizen participation. It has been proven that blockchain acts as the technological basis for institutional change through three mechanisms: decentralization of trust, automation of execution through smart contracts, and immutability of records. Key institutional transformations influenced by blockchain technologies have been identified: the transition from representative to participatory and “liquid democracy” (a hybrid model of political governance that combines elements of direct and representative democracy, allowing citizens to flexibly choose between personal voting and delegating their vote to trusted representatives with the possibility of revoking this delegation at any time), the replacement of centralized control with decentralized verification, and the transformation of the trust economy from institutional to cryptographic. It is argued that blockchain creates a new architecture of state power, where traditional hierarchical structures are complemented by network forms of organization and decentralized autonomous organizations. The Ukrainian context of digital transformation of public administration is analyzed, including the experience of creating the Ministry of Digital Transformation, implementing the Dія ecosystem, and developing blockchain registries. Specific challenges to the implementation of blockchain technologies in Ukraine have been identified: legal barriers, the digital divide, bureaucratic resistance, and the need to ensure cybersecurity in the context of hybrid warfare. The novelty of the research lies in the development of a conceptual model of blockchain-mediated institutional transformation of public administration, which integrates the theory of neo-institutionalism with the concept of democracy 3.0. The practical value of the results is determined by the possibility of using the proposed approaches to form public policy on the digitalization of the public sector in Ukraine. Prospects for further research include empirical verification of the proposed model, development of metrics for evaluating the effectiveness of blockchain solutions in public administration, and research on the socio-psychological factors of citizens’ acceptance of decentralized forms of participation in public administration.

the paper examines the phenomenon of decentralized finance (DeFi) as one of the most promising and at the same time controversial areas of the digital economy. DeFi is defined as an ecosystem of protocols and applications based on blockchain and smart contracts that allows financial transactions to be carried out without the intermediation of traditional institutions. It is noted that the key advantages of the technology are transparency, automation, reduction of transaction costs, and expansion of the accessibility of financial services. Simultaneously, risks associated with the lack of unified regulatory approaches, high vulnerability of smart contracts, the use of DeFi for unlawful purposes, and the uncertainty of legal liability are emphasized. Particular attention is paid to AML/KYC problems, as well as the use of DeFi platforms for money laundering of criminal proceeds.

The paper studies DeFi (decentralized finance) as a decentralized system for the circulation of financial tokens in virtual and cryptocurrency spaces. The subject of the study is the basic concepts, structures, and properties of DeFi. The relevance of the work is determined by the presence of unresolved issues related to the conceptual apparatus and structure of DeFi, factors of reduction and methods for determining the level of decentralization of DeFi, the functioning of the DeFi infrastructure, which highlights the need for further research into the concepts, structures and properties of DeFi. The aim of the study is to form a theoretical and methodological foundation for DeFi by clarifying the conceptual apparatus and identifying the features of DeFi functioning. The methodological framework of the study is based on the following principles: an object-subjective approach to describing entities, a method of structural analysis of objects, a systems approach to model objects, a process approach to analyzing the functioning of systems, and a service approach to analyzing interactions between serving and served systems. The study resulted in the formulation of the concept of DeFi (including the concept of a decentralized system). The following were identified: factors of centralization (reduced decentralization) of DeFi; the structure of DeFi as a set of subsystems for the circulation of virtual financial tokens and crypto tokens; a method for assessing the degree of DeFi decentralization as a system for the circulation of digital financial tokens; a three-tier service model of the DeFi infrastructure; and a model for the interaction of financial token circulation processes. Conclusions: The conceptual framework of DeFi, including the definition of DeFi as a decentralized system for the circulation of financial tokens in virtual and crypto spaces, allows us to identify the functional features of DeFi that ensure conditions for significantly greater transparency of the rules and results of financial transactions compared to traditional centralized financial systems. The use of virtual and crypto tokens, along with other DeFi mechanisms in financial circulation, significantly reduces uncertainty and the associated risks of executing financial agreements between economic entities.

The work is devoted to an overview of modern investment methods, the cryptocurrency market, ways of their development and strategies in this direction. The article analyzes the investment opportunities of cryptocurrencies; presents conclusions about the main advantages and disadvantages of each investment method, the level of risk, determining factors and investment attractiveness. The article considers one of the main methods of investing in cryptocurrency - speculation on the rates of various coins. In particular, two strategies for generating income through speculation are considered: the first is Buy&Hold, it is designed for long-term investment, involves buying cryptocurrency on the exchange and storing it in an account for a certain period of time; the second - the Buy&Sell strategy differs from the previous one in that it is designed for short-term investment. The presented work briefly describes a widely known method of investing in cryptocurrency - mining; in this case, all activities are based on blockchain technology, and the efficiency of the blockchain directly depends on the computing power of the computer. As a result, the profitability of mining is relatively low, special, very expensive equipment is required; In this paper, we have studied and tried to convey to the reader a widespread method of investing in cryptocurrency — initial coin offering (ICO), which means a form of attracting investment funds for the implementation of a project by issuing cryptocurrency. It is argued that the above tactics are also borrowed from the traditional financial market — initial public offering (IPO). In conclusion, the article summarizes the pros and cons of cryptocurrency investment methods; several simple recommendations are presented that will help increase your existing capital and diversify your investment portfolio.

Topicality. The current stage of economic development is characterized by rapid changes occurring under the influence of digitalization. One of the most characteristic phenomena of the digital economy is the proliferation of cryptocurrencies. This trend opens up new opportunities for financial transactions, but at the same time creates significant challenges for legal regulation, accounting standards and tax policy. Aim and tasks. The purpose of this study is a comprehensive analysis of the theoretical foundations, the regulatory framework, and the existing practical approaches to accounting and taxation of cryptocurrency in conditions of legislative uncertainty in Ukraine. Materials and methods. The study is based on existing works by authors that cover the issues of accounting and taxation of cryptocurrency, which allows us to study the development of this problem in the economic sphere. The methods of the system approach, general scientific methods of analysis and synthesis, comparison, classification, induction and deduction were used. Research results. The theoretical and methodological foundations of accounting and taxation of cryptocurrency were studied, in particular, an analysis of approaches to defining the concept of «cryptocurrency» was conducted, global trends in the regulation of transactions with crypto assets were studied, and the views of domestic scientists on this issue were summarized. The application of international accounting standards is justified and relevant recommendations for accounting for cryptocurrency are developed, which depend on the purpose of its holding. Conclusion. The urgent need for a comprehensive modernization of the national regulatory framework is substantiated. This includes legislative regulation of the legal status of cryptocurrency, the introduction of relevant provisions on accounting for digital assets into the NAS (National Accounting Standards), the formation of a clear mechanism for taxation of transactions with virtual assets, and harmonization of national approaches to financial reporting with IFRS (International Financial Reporting Standards).

Topicality. The digitalization of the economy in the context of the Fourth Industrial Revolution fundamentally changes the logic of the functioning of economic systems. Industry 4.0 encompasses a range of breakthrough technologies, such as artificial intelligence (AI), the Internet of Things (IoT), blockchain, cloud computing, 3D printing, big data, and robotics, which not only modernize production but also transform value creation processes, labor organization, consumption, and governance. This creates a need for scientific reflection on these processes, taking into account economic, social, and institutional aspects. Existing theoretical models do not fully explain the new patterns of economic development under conditions of digital transformation, which necessitates research into the mechanisms of structural change. Aim and tasks. The purpose of the article is to substantiate the mechanisms and forms of structural transformation of the economic system under the influence of the core technologies of Industry 4.0. In particular, the study examines how digital and autonomous solutions change the nature of production, distribution, consumption, and management. Materials and methods. The methodological basis of the study is a set of scientific approaches. The systems approach made it possible to consider digital technologies as a unified architectonics of a transformation model. Structural and logical analysis was used to identify the key directions of change: what is produced, how it is produced, and for whom. Comparative analysis was applied to contrast the classical “push economy” model with the modern “pull economy,” as well as human-centered and automated management solutions. Research results. The study established that the widespread implementation of Industry 4.0 technologies leads to systemic changes in the key parameters of the functioning of the economic system, namely the transformation of the coordinates “what to produce,” “how to produce,” and “for whom to produce.” It is proven that the integration of artificial intelligence, additive technologies (3D printing), and big data forms a model of customized, autonomous, and localized production, which is accompanied by a shortening of value chains and an increase in the flexibility of production processes. It is substantiated that blockchain technologically ensures a reduction in transaction costs and the decentralization of coordination mechanisms, while robotics drives productivity growth, and cloud computing and the Internet of Things ensure the rapid synchronization of production with real demand and enhance the adaptability of economic systems. Conclusion. The generalization of the obtained results allows us to assert that Industry 4.0 technologies form a qualitatively new architecture of the economic system, manifested in the transition from an extensive to an intensive model of economic growth, from a “push” to a “pull” logic of economic functioning, from mass to customized production, and from centralized to decentralized data management models. The identified shifts indicate the transformation not only of individual production or management processes but of the holistic structure of the economic system under the influence of digital technologies.

The article explores the institutional paradigm of the transformation of the global financial architecture under the conditions of digitalization of the global economy. It is substantiated that the proliferation of digital financial technologies, including fintech innovations, crypto-assets, decentralized finance (DeFi), and central bank digital currencies (CBDCs), generates profound structural shifts in the functioning of the global financial system and necessitates a reconsideration of the role of key institutions of international financial governance. The study analyzes the evolution of the roles of central banks, international financial institutions, national regulators, and private financial technology companies in shaping the new global financial landscape. It is determined that central banks are gradually transforming from traditional monetary regulators into key architects of digital financial infrastructure, while private fintech and BigTech companies are becoming systemically important actors capable of influencing payment systems, financial inclusion, and cross-border financial flows. Particular attention is devoted to the analysis of contemporary global trends in the implementation of CBDCs, the development of crypto-asset markets, and decentralized financial platforms. It is demonstrated that these processes are forming a hybrid model of financial globalization that combines elements of centralized regulation with decentralized financial mechanisms. The article highlights key initiatives of international coordination and regulatory harmonization implemented within the frameworks of the Bank for International Settlements (BIS), the International Monetary Fund (IMF), the Financial Stability Board (FSB), and the G20, aimed at ensuring financial stability, cybersecurity, and preventing regulatory arbitrage. Based on the conducted analysis, an institutional model for the transformation of the global financial architecture is proposed, grounded in the integration of international standardization, public–private partnership, and multi-stakeholder interaction. It is proven that the effectiveness of the digital transformation of the global financial system depends on the capacity of international institutions to adapt regulatory approaches to dynamic technological changes and to ensure a balance between innovation, financial stability, and economic security.

This article examines the theoretical and methodological foundations of local budget management within the public finance system, specifically addressing the complex challenges of wartime and post-war recovery. The research systematizes diverse scientific approaches to positioning local budgets, proposing a refined definition of the local budget as a multi-functional financial instrument essential for regional strategic development and the provision of public services. The study argues that the multifaceted role of the local budget is a prerequisite for ensuring the socio-economic security and stability of territorial communities amidst current military and economic pressures. The authors establish that efficient public finance management is fundamental to national economic growth and financial system stability. A primary contribution of the research is the development of a conceptual model for local budget management, structured as an integrated complex with clearly defined objectives, subjects, and functional principles. This model incorporates regulatory, legal, and informational support mechanisms, allowing for the effective allocation of funds and increased transparency in the context of decentralization. The study emphasizes that both internal and external factors determine the effectiveness of decision-making and the choice of regional management strategies. Ultimately, the proposed model enhances the accountability of local authorities and reduces uncertainty in financial activities. By providing a framework for robust budgetary analysis, this conceptual approach fosters sustainable development and strengthens the financial capacity of Ukrainian regions. The findings provide a theoretical basis for improving the budgetary security of territorial communities during both conflict and reconstruction phases.

Financial innovations have emerged as one of the most influential forces shaping contemporary commerce, redefining the mechanisms through which businesses operate, transact, and compete. As global markets become increasingly interconnected and digitalized, the demand for more efficient, secure, inclusive, and scalable financial systems continues to grow. This research article investigates the multi-dimensional role of financial innovations—spanning digital payments, block chain technologies, neobanking, artificial intelligence in finance, and alternative lending models—and examines how these advancements are reshaping commercial practices, market structures, and customer experiences. The study draws from established literature, recent empirical findings, and theoretical frameworks to provide a comprehensive understanding of how financial innovations contribute to transactional efficiency, risk management, cost reduction, and value creation within commerce. The article further explores how financial innovations facilitate business expansion, enhance consumer accessibility, and support regulatory compliance through technologies such as RegTech and Insur Tech. Special emphasis is placed on the convergence of financial services with digital commerce platforms, leading to embedded finance models and the democratization of financial access for micro, small, and medium enterprises (MSMEs). Additionally, the study highlights emerging trends including decentralized finance (DeFi), tokenization of assets, real-time data analytics, and the growth of digital currencies—each of which represents a new frontier in commercial transformation. The findings suggest that while financial innovations bring unprecedented opportunities for growth, they also introduce challenges related to cyber security, regulatory uncertainty, data privacy, and operational risks. The paper concludes by identifying key future prospects and research directions, emphasizing the need for stronger governance models, global regulatory harmonization, and interdisciplinary research to unlock the full potential of financial innovations in commerce. The study contributes to ongoing scholarly discourse by offering a holistic and forward-looking perspective that can guide policymakers, businesses, researchers, and financial institutions.

The article presents an in-depth analysis of international approaches to the taxation of virtual assets, covering cryptocurrencies, decentralized finance instruments, non-fungible tokens, airdrops, and hard forks. The research is based on a comparative study of tax regimes in the United States, Germany, Switzerland, Estonia, Singapore, Portugal, and Australia. The analysis addresses differences in legal definitions, rules of income and capital gains taxation, valuation methods, and the application of value-added or goods and services tax. Attention is paid to compliance mechanisms and administrative practices that influence taxpayer behavior and shape levels of adoption. To complement the legal comparison, the study incorporates empirical data from the Global Crypto Adoption Index, allowing for an evaluation of the link between regulatory clarity, tax burden, and the spread of digital assets in different countries. A special focus is placed on Ukraine, which has legally recognized virtual assets through the Law “On Virtual Assets” while awaiting the implementation of Draft Law No. 10225-д to introduce taxation rules. These reforms are assessed in the context of international standards developed by the Organisation for Economic Co-operation and Development, the Financial Action Task Force, and the European Union. The article emphasizes the risks associated with gaps between formal legislative alignment and actual enforcement capacity in transition economies. Excessive or unclear taxation is shown to contribute to capital outflow, informal practices, and regulatory arbitrage. The article further explores underregulated areas such as staking, token swaps, and the creation and trade of non-fungible tokens. It argues that updated tax guidance and coordinated cross-border measures are necessary to provide legal certainty and prevent systemic risks. The role of blockchain analytics, identity verification, and international information-exchange regimes is highlighted as a foundation for more effective oversight. The novelty of the study lies in combining doctrinal legal analysis with fiscal assessment and comparative empirical indicators, which makes it possible to identify both universal patterns and national specificities. The conclusions stress that sustainable taxation of virtual assets requires transparent, balanced, and enforceable rules supported by international coordination. Such an approach not only ensures stable public revenues but also fosters responsible financial innovation and strengthens the integration of Ukraine into the global digital economy.

Uhryn A.P. FINANCIAL SUPPORT FOR THE DEVELOPMENT OF LOCAL COMMUNITIES IN DEVELOPED COUNTRIES: IMPLEMENTATION IN DOMESTIC PRACTICE Purpose. The aim of the article is to summarise and systematise international experience in financial support for the development of local communities in developed countries and to substantiate the directions for its implementation in domestic practice, taking into account the tasks of strengthening the revenue base of local budgets in Ukraine, increasing the institutional stability of communities and ensuring their sustainable development in the context of post-war recovery and budget decentralization. Methodology of research. The methodological basis of the study is the systemic and institutional approaches, which made it possible to consider local finances as a complex multi-level system in which budgetary, tax, and transfer mechanisms interact within the current institutional environment. In the process of research, comparative analysis methods were used to compare models of local finance organization and mechanisms of fiscal decentralization in different countries, logical generalization to form theoretical conclusions and conceptual provisions, as well as structural and functional analysis to identify the role of individual elements of the budget system in ensuring the financial autonomy of local self-government. Thus, the research methodology is based on a comprehensive combination of modern theoretical and methodological approaches to analysing the functioning of the public finance system in decentralized conditions. The theoretical basis of the work is formed by the provisions of the theory of fiscal federalism, which reveal the patterns of distribution of revenue and expenditure powers between levels of government, the concept of tax autonomy of territorial communities, as well as scientific approaches to inter-budgetary equalization as a tool for ensuring financial capacity and balanced regional development. Findings. It has been established that the effectiveness of financial support for local communities is determined by a balanced combination of tax autonomy, stable own and fixed revenues, as well as effective mechanisms of vertical and horizontal financial equalisation. The institutional features of decentralised, cooperative and centralised models of local finance, their impact on the financial stability of communities and the quality of public services are revealed. It is substantiated that Ukraine's priorities are: strengthening the role of personal income tax and property tax in local budget revenues, improving formula equalisation based on European models, developing municipal investment and project financing instruments, and integrating international aid into the local finance system while maintaining budgetary discipline. The obtained results correspond to the tasks of improving the effectiveness of community’s information and communication resources and strengthening the financial capacity of territories. Originality. International models of financial support for territorial communities have been systematised through the prism of combining tax autonomy and solidarity mechanisms; adaptation guidelines for Ukraine have been substantiated, combining the expansion of communities' own revenue base with the improvement of inter-budgetary relations and the strengthening of the financial responsibility of local self-government bodies. Practical value. The proposed approaches can be used by public authorities and territorial communities of Ukraine to form a sustainable revenue policy, optimise the financial equalisation system, plan development investments and improve the quality of budget management. The research results are relevant to scientific and practical tasks of improving local budget revenue management and introducing strategic risk management into community activities. Key words: financial support for local communities, fiscal decentralization, local budgets, tax autonomy, inter-budgetary relations, financial equalisation, post-war recovery.

To assess the fiscal effects of the reform, comparative and dynamic analysis methods were used, as well as statistical methods for processing official data from the Ministry of Finance of Ukraine and the state budget web portal for citizens. The phasing of fiscal decentralization was substantiate using an institutional approach and elements of the concept of fiscal federalism. Findings. The article proves that fiscal decentralization reform in Ukraine had an uneven fiscal effect in the short term, but in the long term contributed to the growth of financial independence of local budgets. It has been established that in 2011–2014, the revenue base of local budgets was characterized by high dependence on interbudgetary transfers and the limited role of local taxes. The introduction of the reform in 2015 was accompanied by a temporary decrease in the share of own revenues due to the revision of personal income tax (PIT) crediting standards, but in 2016–2019, there was a gradual strengthening of the tax capacity of communities. It has been substantiated that the sharp reduction in official transfers in 2020 and 2022 was due to the completion of the administrative and territorial reform, the COVID-19 pandemic and the transition of the budget system to functioning under martial law. Originality. A comprehensive analysis of fiscal decentralization was conducted from the perspective of its pragmatic impact on the formation of local budget revenues in the long term. The author proposes an approach to the periodization of fiscal decentralization reform in Ukraine, taking into account institutional changes and crisis factors, and substantiates the relationship between the transformation of interbudgetary relations and the dynamics of tax revenues at the subnational level. Practical value. The obtained results can be used by state authorities and local self-government bodies in the formation of tax and budget policy, the improvement of interbudgetary equalization mechanisms and the development of a post-war strategy for the development of fiscal decentralization. Key words: fiscal decentralization, fiscal federalism, fiscal policy, local budgets, taxes, tax revenues, interbudgetary transfers, territorial communities, personal income tax.

This paper examines factors that influence prices of most common five cryptocurrencies such as Bitcoin, Ethereum, Dash, Litecoin, and Monero over 2010-2018 using weekly data. The study employs ARDL technique and documents several findings. First, cryptomarket-related factors such as market beta, trading volume, and volatility appear to be significant determinant for all five cryptocurrencies both in short- and long-run. Second, attractiveness of cryptocurrencies also matters in terms of their price determination, but only in long-run. This indicates that formation (recognition) of the attractiveness of cryptocurrencies are subjected to time factor. In other words, it travels slowly within the market. Third, SP500 index seems to have weak positive long-run impact on Bitcoin, Ethereum, and Litcoin, while its sign turns to negative losing significance in short-run, except Bitcoin that generates an estimate of -0.20 at 10% significance level. Lastly, error-correction models for Bitcoin, Etherem, Dash, Litcoin, and Monero show that cointegrated series cannot drift too far apart, and converge to a long-run equilibrium at a speed of 23.68%, 12.76%, 10.20%, 22.91%, and 14.27% respectively.

The article explores the theoretical and methodological principles of integrating the organizational and economic potential of Blockchain technologies into the agribusiness system in the context of increasing demands for transparency and sustainability of value chains. The essence of Blockchain is revealed as a tool for forming a trusted information infrastructure that ensures data immutability, transaction automation and business process optimization based on smart contracts. It is substantiated that the use of distributed ledger technologies contributes to the decentralization of management, reduction of transaction costs, digitalization of product quality control and increase of the export potential of agricultural enterprises. Scientific approaches to the development of Blockchain solutions for agri-food supply chains are analyzed. A mechanism for integrating Blockchain into centralized and decentralized agribusiness platforms is proposed, which involves the development of digital competencies, the creation of support infrastructures and indicators for assessing the readiness of enterprises to implement distributed ledger technologies.

We examine the qualifying attributes of decentralized finance (DeFi) as a financial asset class. To achieve this objective, we perform analysis on the relationship (using both level and percentage-change data) between DeFi valuation and selected influencing variables, namely total value locked (TVL), Bitcoin (BTC) value, and market variables. A suite of long-panel data econometric methods is employed on a multi-frequency (daily, weekly, and monthly) panel dataset comprising 16 major DeFi protocols from January 2022 to December 2023. Our empirical design aims to be a comprehensive assessment and triangulation. There are several key findings. First, while there is evidence of cointegration suggesting a possible long-run relationship, this relationship is found to be inconsistent across different variables and time frequencies. However, the impulse response analysis suggests that shocks from the influencing variables do not have a permanent impact. Second, Bitcoin value is found to be the most important influencing factor (positive and highly significant), reflecting strong cryptocurrency market sentiment and aligning with previous research on spillover effects from major cryptocurrencies (Șoiman et al., 2022; Yousaf et al., 2022).
