Stablecoins have been heralded as the future of money on distributed ledgers. As was discussed in the previous chapter, stablecoins purport to mitigate the wild fluctuations that are experienced by cryptocurrencies such as Bitcoin by providing for a one-to-one reserve of a denominated fiat currency that holders can redeem at any time. Yet, despite these built-in mitigating factors, stablecoins have still been plagued by runs and a lack of transparency into their operations. As such, the Central Bank Digital Currency (CBDC) provides an interesting opportunity to see if the digital equivalent of fiat currency can offer increased efficiencies over conventional paper-based currency. 1 Moreover, can these efficiencies be leveraged to other sectors of the economy thereby stimulating more economic growth for all?
The article examines the essence of cryptocurrency as one of the key factors for the development of an innovative economy in the context of the digitalization of financial relations. The evolution of approaches to defining the concept of cryptocurrency is considered, the positions of international organizations are analyzed, and the author's interpretation of this category is proposed as a virtual currency that functions on the basis of cryptographic protection methods and is capable of performing the functions of a means of payment, a means of accumulation, and an object of property.Particular attention is paid to the comparative analysis of cryptocurrency and electronic money, as a result of which their common features and fundamental differences are determined, in particular the decentralized nature of cryptocurrencies, the absence of an emission center and financial intermediaries. The mechanisms of functioning of cryptocurrency transactions and the features of using blockchain technology are studied.The article systematizes the advantages and disadvantages of cryptocurrencies. The main advantages include a high level of data protection, impossibility of forgery, low transaction costs, and deflationary nature. At the same time, key risks have been identified, including high volatility, lack of proper legal regulation, and increased fraud threats.The current state of the crypto market has been analyzed, in particular the distribution of cryptocurrencies by capitalization level and the assessment of their risk and profitability. It has been established that the market is characterized by high capital concentration and the dependence between the level of risk and the potential return on assets.Special attention is given to unresolved issues in the field of cryptocurrency research, including the lack of a unified theoretical approach to defining its economic nature, the ambiguity of its legal status, and the challenges of integrating cryptocurrencies into the traditional financial system. The methodological basis of the study includes a systematic approach, a comparative analytical method, as well as methods of generalization and abstraction, which made it possible to comprehensively assess the role of cryptocurrencies in modern economic processes.The practical significance of the obtained results lies in the possibility of using them to improve approaches to the regulation of the cryptocurrency market, risk assessment, and the development of innovative financial instruments. It is substantiated that cryptocurrencies play an important role in the formation of an innovative economy, contributing to the development of new financial instruments, digital platforms, and decentralized models of economic interaction.

The article examines the role of digital transformation as a key factor in strengthening the economic and legal resilience of Ukrainian cities in the context of global competition, governance decentralization, and unprecedented geopolitical challenges. It is substantiated that the digitalization of municipal governance is becoming an important tool for increasing the adaptability of local economic systems, ensuring the continuity of public services, and creating a transparent legal environment for business activities. Particular attention is paid o the concept of “digital legal immunity,” which is defined as an integrated system of technological, organizational, and regulatory mechanisms aimed at ensuring the protection, autonomy, and stability of critical municipal data and information infrastructure. The study analyzes the impact of modern digital instruments, including cloud-based registries, automated electronic document management systems, blockchain solutions in property and land relations, and digital platforms for interaction between public authorities, businesses, and citizens. It is demonstrated that the implementation of such tools contributes to reducing transaction costs, lowering administrative barriers, increasing transparency in governance procedures, and minimizing corruption risks. The paper argues that the integration of digital technologies into local regulatory development programs, particularly within initiatives such as “Digital City” and “Digital Community,” helps create a predictable regulatory environment, stimulates capital circulation, and enhances the investment attractiveness of territories. Based on the analysis of digitalization practices in leading Ukrainian cities (Kryvyi Rih, Dnipro, Ternopil, Uzhhorod, Vinnytsia, Lviv, and Kharkiv), the study systematizes strategies for the capitalization of digital assets and identifies their impact on the economic and legal sustainability of urban systems. Three key levels of institutional support for digital transformation are distinguished: strategic planning and regulatory legitimization of digital initiatives; the creation of local regulatory sandboxes for testing innovative technological solutions; and the regulation of digital interaction between local authorities, residents, and business entities. It is proven that under decentralization conditions, digitalization gradually transforms the city into an autonomous digital governance entity capable of responding promptly to external challenges, mitigating the risks associated with centralized management systems, and ensuring the uninterrupted functioning of municipal services even during crisis or wartime conditions. The obtained results highlight the systemic role of digital transformation in strengthening the economic and legal resilience of Ukrainian cities and outline promising directions for further research related to the quantitative assessment of the impact of digital platforms on governance risks, investment attractiveness, and the stability of local economies.
Relevance. Problem statement. The rapid development of Decentralized Finance (DeFi) and the expansion of blockchain technologies within the digital economy and the broader process of financial digitalization complicate the application of traditional approaches to accounting and taxation of digital assets. The absence of clear criteria for interpreting the economic substance of DeFi and its implications for the recognition, measurement, and disclosure requirements of digital assets leads to heterogeneity in accounting practices, reduced comparability of financial reporting, and increased risks for auditors and investors. Consequently, there is a need to identify accounting-relevant characteristics of DeFi that can serve as a basis for accounting decisions regarding digital assets and for establishing a unified approach to their classification and measurement in accordance with International Financial Reporting Standards (IFRS). The purpose of the article is to provide a conceptual justification and structured generalization of the impact of DeFi and blockchain technologies on the methodology of accounting for digital assets through the identification of accounting-relevant characteristics that determine the specific features of their recognition, measurement, and disclosure in financial statements in accordance with IFRS, as well as their implications for the formation of tax liabilities within the DeFi environment. Methodology. The research objectives were addressed using general scientific and specialized methods, including analysis, synthesis, induction, deduction, comparison, abstraction, and a systems approach, which ensured an appropriate level of substantiation of the proposed arguments and the formulation of well-grounded conclusions. Results. The findings indicate that the transactional transparency of blockchain is accompanied by new valuation risks that affect asset measurement and revenue recognition. Existing tax regulations often fail to account for the specific characteristics of the DeFi ecosystem. Accounting-relevant characteristics of DeFi have been systematized, demonstrating that their influence extends beyond the accounting treatment of digital assets to the specific features of the protocol-based financial architecture within which economic rights and obligations are executed through algorithmic mechanisms without a centralized counterparty. Their systemic impact on the application of control criteria, the determination of the existence of contractual rights to claims, the selection of measurement models, the identification of the timing of revenue and liability recognition, and the scope of risk disclosures under IFRS has been substantiated. The theoretical contribution of the results lies in shifting from a descriptive analysis of blockchain technology to a structured accounting interpretation of DeFi from the perspective of control, measurement, and risk management concepts. Practical significance. The identification of accounting-relevant characteristics of DeFi is essential for developing a systematic approach to accounting for digital assets in a decentralized environment, as the protocol-based ecosystem of DeFi fundamentally alters the nature of the emergence of rights and obligations as well as the accrual of income, directly affecting the application of IFRS requirements. Such an approach ensures conceptual consistency between technological innovations and the regulatory framework of accounting and enhances the quality of financial information under conditions of financial system digitalization. The practical significance of the study lies in establishing a basis for updating corporate accounting policies and developing tax instruments that promote transparency and reduce risks in the digital asset sector. Prospects for further research. Future research should focus on improving disclosure standards and developing algorithmic models for the automated identification of economic transactions and tax events based on on-chain data.
The rapid development of financial technologies and the spread of blockchain infrastructure have contributed to the emergence of new digital financial assets, among which stablecoins hold an important place. Unlike traditional cryptocurrencies, they are characterized by relative price stability, which is ensured by pegging to fiat currencies, commodity assets, or the use of algorithmic mechanisms for regulating token supply, creating conditions for their use in payment systems, international settlements, and decentralized financial services. The aim of the article is to study the economic essence of stablecoins, determine their role in modern payment systems, and analyze trends in the development of the stable digital asset market based on an assessment of their market capitalization. In the course of the research, general scientific and specialized methods of scientific knowledge were used, in particular methods of system analysis, generalization, comparative analysis, and structural study of the crypto-asset market. The article examines approaches to the classification of stablecoins depending on the type of their backing, in particular fiat-backed, commodity-backed, crypto-backed, and algorithmic stablecoins. The main directions of the use of stablecoins in the modern financial infrastructure are identified, including cryptocurrency exchanges, decentralized finance platforms, and cross-border payments. A comparative analysis of traditional payment systems and payment systems based on stablecoins was carried out, which made it possible to determine their advantages in transaction speed, global accessibility, and reduction of transaction costs. Special attention is paid to the analysis of the market structure of stablecoins. It was found that at the beginning of 2026, the total capitalization of this segment exceeds USD 300 billion, which indicates its rapid growth. At the same time, the market is characterized by a high level of capital concentration, as more than 80% of its volume is concentrated in the two largest stablecoins, namely USDT and USDC. As a result of the study, it was concluded that stablecoins are gradually transforming from an auxiliary tool of cryptocurrency trading into an important element of the global payment infrastructure. A further development of this segment will depend on the improvement of regulatory mechanisms, increased transparency of reserve backing, and the integration of stablecoins into the traditional financial system.
Стаття присвячена створенню мультимодальної системи прогнозування Bitcoin, яка об’єднує традицiйнi ринковi показники з аналiзом новин через нейромережi LSTM та GRU.

The article is devoted to the development of a hybrid strategy for the innovative growth of the Ukrainian neobank Monobank through the integration of cryptocurrency services in the context of the draft law on cryptocurrency legalization under consideration in the Verkhovna Rada. The relevance of the study is determined by the need to diversify neobanks’ income sources amid market saturation and regulatory changes in the field of digital assets. The classification of Monobank as a neobank is substantiated according to the criteria of the European Banking Authority: a fully digital model without physical branches, a client-centric business model, its own technological platform, and a methodology for rapid product development. A SWOT analysis of the bank’s competitive position revealed an imbalance between opportunities and threats under martial law, cyber risks, and regulatory uncertainty. A comparative analysis of the crypto-strategies of international neobanks Revolut and Nubank confirmed the advantages of the intermediary role over issuing a proprietary token. Revolut’s success is based on phased integration and obtaining regulatory licenses, while Nubank’s failure with its own token demonstrates the risks of hasty decisions without a clear regulatory strategy. The concept of the Monobank Crypto Hub has been developed with a three-phase implementation: the first stage focuses on basic functionality with mandatory transaction limits and an educational module to minimize reputational risks; the second stage provides for expanded functionality through staking and premium subscription; the third stage includes a full ecosystem with crypto-deposits and integrations with decentralized finance protocols. Financial modeling demonstrates a gradual achievement of break-even with emphasis on managing operational and reputational risks. The practical value of the study lies in the formation of a concrete roadmap for crypto-integration for Ukrainian fintech companies.
The article explores cryptoeconomics as a new paradigm for the development of transaction theory and financial intermediation in the context of the digital transformation of the global economy. It is substantiated that the rapid introduction of blockchain technologies, smart contracts and asset tokenization mechanisms causes qualitative changes in the ways of organizing economic interaction, forming a transition from institutionally mediated to algorithmically managed trust systems. The evolution of theoretical approaches to transaction costs is revealed, in particular in the context of the ideas of R. Coase, O. Williamson and D. North, and their transformation in the digital environment is proven, where the key functions of coordination, control and verification are implemented through decentralized protocols. It is established that cryptoeconomics forms a new structure of transaction costs, in which the costs of coordination, monitoring and ensuring the execution of transactions are reduced, while the costs associated with the functioning of the network infrastructure appear. The main characteristics of the cryptoeconomic environment are highlighted: transparency, self-fulfillment of transactions, distributiveness of risks, autonomy of economic agents and the algorithmic nature of trust. Particular attention is paid to the role of decentralized finance (DeFi) and decentralized autonomous organizations (DAO) as new forms of organization of financial relations. A conceptual model of “new transactionality” is proposed, within which economic relations acquire a network character, and cryptocurrencies perform not only the function of a financial asset, but also an institutional mechanism of market self-regulation. It is proved that trust is transformed from a socio-legal category into a technologically guaranteed property of the protocol. It is concluded that cryptoeconomics forms the basis for the formation of a new financial architecture based on the principles of decentralization, digital trust and algorithmic management, determining the strategic directions of development of global economic systems in the 21st century
The introduction of Central Bank Digital Currency (CBDC) is a game-changer in the world of global money. Given the digital realm reforming monetary systems, central banks are getting keen on CBDCs to offer a state-backed alternative to private digital currencies and payment systems. This paper aims at carrying out a brief analysis of CBDCs and their impact on monetary sovereignty in view of globalization, technological disruption and rising decentralized finance. Central Bank Digital Currencies (CBDCs) hold promise for bolstering the state’s monetary policy. However, they also pose various challenges to the financial stability of states and cross-border payments involving CBDCs. The study also mentions the changing character of the role of central banks such as the Reserve Bank of India and compares international approaches like the digital yuan of China and the digital euro of the European Union. The paper concludes that CBDCs represent an instrument to strengthen monetary sovereignty as well as a catalyst to redefine monetary sovereignty in the digital age. INTRODUCTION The Money has changed from bartering to metallic coins, paper currency, and now digital currency. Cryptocurrencies like bitcoin have been rising in value at a rapid rate in recent years. As a result, the dollar value and stock markets have been challenged. Decentralized digital currencies trade without a central authority which threatens to undermine the sovereignty of money. #Centralization In this context, countries’ central banks around the world have started to investigate the Central Bank Digital Currency (CBDC). It is a digital form of the sovereign currency that the state issues and regulates. CBDCs are regulated by an authority unlike cryptocurrencies which are decentralized and do not have a backing of a central authority over them. In a rapidly digitalizing economy, states are striving to gain more control over the monetary and financial system.At the heart of this debate surrounding the eurozone members and their exceptional trade ties with Europe lies monetary sovereignty. The emergence of digital currencies private and state raises questions of the future of this sovereignty.The study aims to critically analyze the interrelationship between CBDCs and monetary sovereignty. The implementation of CBDCs allow the central banks to strengthen their control over the monetary authority and also reveal the risks it carry.

The article is devoted to the analysis of the application of cryptocurrency instruments in the diversification of investment portfolios. The study considers specific security risks, high market volatility, and behavioral instability of the digital financial environment. The cryptocurrency market is gradually integrating into the global financial architecture. It demonstrates sensitivity to central bank monetary policy, information flows, geopolitical crises, and technical failures of digital platforms. The purpose of the study is to develop an adaptive model for controlling the risks and volatility of digital assets within a diversified portfolio. The empirical basis was formed using market data for 2023–2025. The analysis covers the dynamics of Bitcoin, Ethereum, stablecoins, decentralized finance instruments, environmentally oriented crypto assets, traditional stock indices, gold-based instruments, and green bonds. The research methodology is based on correlation analysis, volatility spillover modeling, economic and mathematical calculations, Conditional Value at Risk, downside risk assessment, as well as the use of safe haven and portfolio stability indices. The results indicate that digital assets optimize the risk-return ratio only under conditions of limited exposure and regular rebalancing. Empirical data confirm the higher resilience of Bitcoin and stablecoins during banking and inflationary shocks. In contrast, decentralized finance tokens, NFT instruments, and meme coins generate substantial losses and high instability. Based on the obtained results, standard portfolio models were developed for conservative, balanced, institutional, and ESG-oriented investors. The highest stability indicators were recorded in hybrid structures and algorithmic balancing models. These models include automated rebalancing and a moderate share of Bitcoin, stablecoins, environmentally oriented crypto assets, and gold-based instruments. The practical significance of the study lies in the development of methodological recommendations for constructing resilient investment strategies under conditions of increased market instability.

The purpose of this article is to study the role of fintech companies in the digital transformation of the Ukrainian economy, in particular in the context of the financial transformation of agricultural companies, analyze the structure of the fintech ecosystem in different market segments and substantiate mechanisms for overcoming challenges while accelerating economic recovery. The study uses systems analysis, sector impact assessment and comparative institutional analysis. It is established that fintech companies are a strategic tool for financial inclusion, reducing the shadow economy, increasing the transparency of financial reporting of enterprises and harmonizing European regulation, which is important in the process of integrating agricultural companies into international capital markets. The study shows that the fintech ecosystem of Ukraine includes digital payments, mobile banking, peer-to-peer lending, insurance technologies and cryptocurrency trading, and state initiatives, including the Diia platform, the Ministry of Digital Transformation, the Cashless Economy Program and the Digital Agenda, provide the basic infrastructure for digital financial transformation. Ukraine has made significant progress in the penetration of fintech companies and the expansion of the market in the areas of financial services, which creates the prerequisites for increasing the investment attractiveness of enterprises, in particular the agricultural sector. Five systemic challenges are classified: cybersecurity vulnerabilities caused by geopolitical tensions, inequality of digital infrastructure between rural and urban areas, gaps in regulatory acts in the field of decentralized finance and artificial intelligence, talent shortage and professional brain drain, as well as the complexity of compliance with sanctions. Four strategic priorities are substantiated: institutional mechanisms for the development of cybersecurity infrastructure, regulatory "sandboxes" that allow for harmonized testing of innovations with the EU, integrated professional skills programs that address the talent shortage, and international cooperation frameworks that promote cross-border regulatory harmonization and integration into international financial markets. It is predicted that a comprehensive strategic intervention will contribute to increasing the efficiency of financial transformation of enterprises, create significant employment opportunities, and ensure the formation of a competitive financial technology environment that supports the economic recovery and integration of Ukraine into the European financial space.
The article examines financial monitoring in the field of virtual asset circulation, including cryptocurrencies, tokenized assets, and decentralized financial platforms. The rapid expansion of the virtual asset market creates new economic opportunities while simultaneously generating heightened risks related to money laundering, terrorist financing, and sanctions evasion, which necessitates effective regulatory and supervisory responses. Problem statement. The core problem lies in the insufficient alignment of national financial monitoring mechanisms for virtual assets with international FATF standards and European regulatory approaches, as well as the fragmented enforcement practices in Ukraine amid the rapid evolution of the crypto market. Unresolved aspects. Despite ongoing regulatory efforts, significant gaps remain in the effective implementation of FATF Recommendation 15, the operationalization of the Travel Rule, coordination among national supervisory authorities, and oversight of decentralized finance services and cross-border virtual asset transactions. Purpose of the article. The purpose of the study is to conduct a comprehensive analysis of international financial monitoring standards applicable to virtual assets, assess current money laundering and terrorist financing risks, and substantiate directions for improving Ukraine’s regulatory framework in line with FATF requirements and EU practices. Main content. The article analyzes the legal nature of virtual assets, FATF requirements for Virtual Asset Service Providers (VASPs), the application of the Travel Rule, and empirical data on illicit crypto transactions based on Chainalysis reports. Particular attention is paid to the European regulatory model established by the Markets in Crypto-Assets Regulation (MiCA), as well as to the comparative analysis of the concepts of VASP and Crypto-Asset Service Provider (CASP). The current state of legal regulation and financial monitoring of virtual assets in Ukraine is also assessed. Conclusions. The study demonstrates that effective financial monitoring of virtual assets can be achieved only through a comprehensive approach combining FATF international standards, harmonization with EU law, advanced analytical technologies, and strengthened institutional capacity of national regulators. The practical value of the research lies in developing recommendations aimed at enhancing Ukraine’s financial security and reducing money laundering and terrorist financing risks in the virtual asset market.
The development of network-type organizations is accompanied by the transformation of traditional management approaches, particularly the shift from centralized to distributed responsibility within business processes. Such transformation necessitates a reconsideration of management architecture, integrating responsibility into interconnected processes, roles, and digital environments. The study’s relevance stems from the need to enhance organizational flexibility, adaptability, and resilience in dynamic, uncertain environments. The purpose of the study is to identify mechanisms for implementing distributed responsibility in the architecture of business processes in modern network-type organizations, substantiate approaches to integrating it, and analyze its impact on the effectiveness of managerial decision-making and on interaction among process participants. The study applies systemic and process-based approaches, structural-functional analysis, business process modeling, comparative analysis of modern management practices, and the generalization of theoretical provisions on organizational design and decentralized management. It has been established that implementing distributed responsibility involves decomposing business processes into autonomous yet interconnected elements with clearly defined roles and areas of responsibility. The effectiveness of such a model is ensured through the use of digital platforms, horizontal coordination mechanisms, and transparent tools for monitoring task execution. It is substantiated that integrating decentralization principles leads to faster decision-making, greater employee engagement, and reduced managerial risk. The implementation of distributed responsibility in the architecture of business processes forms a new management paradigm focused on flexibility, adaptability, and collaborative interaction. The combination of a process-based approach with network principles of organizational activity enhances the efficiency of modern organizations and lays the groundwork for their sustainable development in the context of digital transformation.
The article examines the role of cryptocurrencies in developing electronic commerce and transforming modern payment infrastructure within the digital economy. Particular attention is paid to the economic nature of cryptocurrencies as innovative financial instruments and their increasing use in online commercial transactions. The study analyzes the key features of applying digital currencies in e-commerce, including decentralization, transaction transparency, the high speed of cross-border payments, and reduced dependence on traditional financial intermediaries. The advantages of cryptocurrency payments over conventional systems are identified, such as lower transaction costs, enhanced security through blockchain technology, and expanded international market access for businesses and consumers. Conversely, the article outlines the main challenges and risks limiting the widespread adoption of cryptocurrencies in electronic commerce. These encompass significant price volatility, technical and infrastructural barriers, cybersecurity threats, and the absence of unified legal regulation across many jurisdictions. Special attention is devoted to analyzing the practical experience of leading international companies–including Amazon, Shopify, PayPal, Microsoft, Expedia, and Rakuten–that have implemented or tested cryptocurrency payment solutions. Results demonstrate that these practices improve payment efficiency, accelerate international settlements, reduce commission fees, and increase overall transaction security. The study concludes that integrating cryptocurrencies into e-commerce represents a natural evolutionary stage of the digital economy. Ultimately, cryptocurrencies possess substantial potential to strengthen electronic commerce and support its ongoing development.
The article carries out a comprehensive theoretical study of the evolutionary transformation of the world financial architecture (SFA) in the context of changes in global technological patterns. The authors analyze the historical retrospective of financial globalization, starting from the moment of laying the foundation of the Bretton Woods system, which determined the hierarchical, dollar-centric structure of international settlements for decades to come. mediated by banking institutions and supranational regulators, at the present stage, is facing a crisis of institutional efficiency caused by the accumulation of global imbalances and the digital divide. Particular attention is paid to conceptually rethinking the transition from the Jamaican monetary system to a new era of “algorithmic order” based on Web3 technologies. It has been established that the key feature of modern transformation is the decentralization of financial relations, where the function of trust is transferred from the institutional level (state and bank guarantees) to the protocol level (distributed ledgers, smart contracts). The authors argue that Web3 does not just modernize payment instruments, but forms a fundamentally new logic of international economic interaction – an ecosystem where capital acquires programmable properties, and cross-border transactions are carried out in real time without the involvement of traditional correspondent networks. The paper details the impact of decentralized finance (DeFi) on the changing role of national currencies and central banks. The thesis that the algorithmization of the financial space requires the development of new approaches to international regulation, since traditional methods of capital control lose their effectiveness in the conditions of anonymous decentralized networks, is substantiated. A forecast is made for the formation of a hybrid architecture of the future, where “fiat” and “algorithmic” orders will coexist through interoperability mechanisms. The article aims to lay a theoretical basis for further study of the mechanisms of adaptation of national economies, in particular Ukraine, to the challenges of global digitalization of finance.
The paper systematizes current regulatory and legal approaches across various jurisdictions, as well as theoretical and methodological recommendations proposed by scholars regarding the identification of different types of digital assets. It substantiates the hierarchical relationship among the concepts of "digital assets", "virtual assets" and "crypto-assets", which describe forms of digital value. The procedure for recognizing digital assets on the balance sheet is clarified. A three-tier classification of digital assets is proposed based on the following criteria: the mode of existence and circulation of digital value, the use of distributed ledger technology, and the mechanism for ensuring value stability. The study develops a sequence for accounting recognition of a digital asset as an intangible asset, a commodity, or a financial instrument, in compliance with accounting standards. It also justifies the classification of certain types of digital assets functionally similar to digital securities, which are recognized as financial instruments.
Purpose: to develop a model of a payment token based on the analysis of its key economic characteristics, such as backing, price stability, liquidity, and volatility. Methods: heterodox, systemic, structural-functional, institutional, cybernetic, and pragmatic methodological approaches to the formation of a cross-border payment infrastructure based on distributed ledger technology; methods of mathematical modeling: descriptive statistics method, index method, normalization method, numerical optimization methods. Results: a payment token model based on a stable currency basket has been developed. Optimal quantitative characteristics of the payment token for use in a cross-border payment infrastructure based on distributed ledger technology have been determined. For the cross-border payment space of the BRICS countries, it is advisable to use a payment token backed by a stable currency basket consisting of the Chinese yuan, Russian ruble, Indian rupee, and Brazilian real. By minimizing the optimization function, the coefficients of the national currencies in the stable basket backing the payment token of the BRICS cross-border payment space have been determined. An alternative model of a payment token backed by a currency basket of Western countries – the US dollar, euro, pound sterling, and yen – has been developed. It is shown that the volatility of tokens based on currency baskets with weights optimized within the proposed model is significantly lower than the volatility of any single currency. Conclusions and Relevance: in the money circulation subsystem of a cross-border payment infrastructure based on distributed ledger technology, it is rational to employ a payment token that meets the economic characteristics of backing, price stability, liquidity, and low volatility. Such a token will ensure the uninterrupted functioning and accessibility of cross-border settlements for economic agents of the BRICS cross-border payment area. The application of an invariant index of the currency value in the design of the payment token model provides a methodological foundation, independent of the choice of a base currency, for optimizing the numerical indicators of its economic characteristics.
The Finance Ministry introduced a flat 30% tax on any income generated from cryptocurrencies in 2022. However, there are multiple legal challenges which have been created due to the imposition of such a tax including lack of differentiation on the basis of the person holding the cryptocurrency, lack of differentiation on the basis of the time for which a cryptocurrency was held, legal ambiguity regarding taxation of mining of cryptocurrencies and lack of provisions for offsetting losses or carry forwarding losses to subsequent assessment year. There is further a regulatory lacuna in enforcement of such taxes imposed on cryptocurrency transactions. This paper delves into highlighting the legal challenges related to imposition of taxes on cryptocurrencies and further provides suggestions to tackle these challenges. It further attempts to suggest a feasible model to ensure effective enforcement of taxation of cryptocurrencies.
The article provides a comprehensive study of the systemic transformation of corporate governance in the context of global digitalization, characterized by the transition from hierarchical models to decentralized structures. It is substantiated that blockchain technology emerges as a new institutional foundation, where traditional bureaucratic verification mechanisms are replaced by algorithms based on cryptographic protocols. A particular emphasis is placed on the distinctions between public (permissionless) and private (permissioned) blockchain networks regarding the immutability of records. The study examines the concept of decentralized governance and the functional specifics of Decentralized Autonomous Organizations (DAOs), where operational logic and management regulations are implemented directly into the software code of smart contracts. This minimizes the influence of traditional administrative management and mitigates "single point of failure" risks. The theoretical framework of the work builds upon classical theories, such as Oliver Williamson’s "Transaction Cost Theory," Michael Jensen and William Meckling’s "Principal-Agent Theory," and the scholarly works of Harold Demsetz. Blockchain is analyzed as a tool that renders market exchange more economically viable than hierarchy. The author proposes an original interpretation of a multi-tier blockchain model for enterprise management, encompassing the infrastructure, network, consensus, data, and application layers. The essence of consensus algorithms (PoW, PoS, DPoS) is disclosed through the prism of management. Special attention is devoted to international experience in legal regulation and the processes of implementing these standards within the legislative framework of Ukraine. The economic effect and practical aspects of the study are analyzed through successful case studies of global corporations (IBM, Amazon, Oracle, Walmart, Nestlé) and Ukrainian business initiatives (TASCOMBANK, SETAM, Agroxy, Softengi). These cases demonstrate a significant reduction in verification costs, lower operating expenses, and increased transparency in supply chains. The transition to an innovative "Management-as-a-Service" paradigm is justified, where blockchain serves not merely as software but as a new firm architecture. Conclusions are drawn regarding a shift in the management ontology – moving from "governance by humans" to algorithmic "governance by code," which ensures data immutability, cyber resilience, and the possibility of real-time preventive risk monitoring.

Purpose. To substantiate conceptual approaches to integrating blockchain technologies into risk management systems of investment activities of financial institutions through systematization of architectural solutions, development of efficiency evaluation criteria, and typology of implementation strategies, taking into account the specifics of different categories of investment risks and regulatory environment. Methodology. An interdisciplinary approach was used, combining institutional analysis of financial systems, comparative analysis of traditional centralized and decentralized risk management models, and systematization of empirical data on blockchain implementation in the global financial sector. Methods of structural-functional analysis were applied to study blockchain systems architecture and their impact on various categories of investment risks. Critical analysis of scientific literature on decentralized finance, asset tokenization, and smart contracts was conducted. Findings. The dual nature of blockchain technologies has been revealed as both a tool for minimizing traditional risks (market, credit, operational, liquidity, regulatory) and a source of new technological challenges. Four integration models have been systematized: asset tokenization for enhancing liquidity, DeFi instruments for decentralized lending and exchange, hybrid portfolios for diversification, and smart contracts for risk management automation. An evaluation matrix for blockchain solutions effectiveness has been developed based on seven criteria (transparency, settlement speed, operational costs, accessibility, reliability, regulatory certainty, scalability) compared to traditional systems. A typology of implementation strategies for commercial banks, investment funds, and insurance companies has been proposed. Originality. For the first time, a comprehensive analysis of the transformation of investment activity risk management architecture through the lens of blockchain technology integration has been conducted, simultaneously considering institutional, technological, and regulatory aspects. A conceptual model of an integrated blockchain system for managing investment risks has been developed with identification of interaction levels and feedback loops. Practical value. Research results form a methodological foundation for financial institutions regarding the selection of optimal blockchain technology implementation strategies, provide tools for evaluating the effectiveness of various integration models, and contribute to the formation of regulatory policy in the field of digital transformation of the financial sector.
