Subject. Regulatory Approaches to Crypto‑Assets in the EU and the USA amid the Formation of a Global Regulatory Architecture for Digital Finance. Objectives. To identify similarities and differences in the regulatory philosophies and institutional mechanisms of the EU and the USA, and to determine the economic consequences of regulatory impact on the global financial system. Methods. A comparative legal institutional analysis was applied, along with general scientific methods. Results. It has been established that the convergence of requirements for stablecoins is taking place amid fundamental differences in institutional architectures: the EU’s centralized model, with ESMA and EBA playing a coordinating role, is contrasted with the decentralized US dual banking system, where supervisory powers are distributed among the OCC, the Federal Reserve, the CFTC, and the SEC. Recommendations have been formulated for market participants and regulators to navigate the conditions of regulatory fragmentation. Conclusions. Positions regarding central bank digital currencies are diametrically opposed, which creates strategic risks for the international monetary system; regulatory differences generate risks of global market fragmentation and regulatory arbitrage.
The present research explores how blockchain technology and cryptocurrencies challenge the traditional continental civil law framework. By reassessing the legal taxonomy of digital assets, the paper argues against their strict classification as jura in personam, primarily due to the absence of a designated debtor in permissionless networks. Alternatively, it supports the recognition of a sui-generis real right (jus in re) grounded in the concept of ‘cryptographic possession’. Furthermore, classical civil classifications are reinterpreted to address the ubiquitous nature of digital assets and the inherent complexities of jurisdictional localization. The study highlights the legal distinction between fungible cryptocurrencies and Non-Fungible Tokens (NFTs), alongside the emerging fructiferous character of assets deployed within Decentralized Finance (DeFi) ecosystems, which generate civil fruits. To contextualize these shifts, three European regulatory paradigms are evaluated: the French dualist approach under the PACTE Law, the German institutional integration into the banking sector, and the Swiss DLT framework, which innovatively merges substantive rights with digital tokens. Finally, the analysis focuses on the practical implications for the pathology of legal relations, particularly regarding the efficacy of forced execution and the safeguarding of the creditors' general pledge. The paper concludes with targeted de lege ferenda proposals for the Romanian legal system. These include the express statutory recognition of digital assets as intangible movable property in the Civil Code, alongside modern civil procedure mechanisms, such as the judicially mandated surrender of private keys under penalty and automated electronic garnishment, aimed at harmonizing state coercive power with the realities of the Web 3.0 economy.
The article considers current legal issues of implementation and use of smart contracts in the sphere of capital construction. It is shown that an objective need of capital participants to conduct electronic transactions, store and process legally significant information, and conclude smart contracts has been formed. The rapid development of high technologies has inevitably led to the need to use smart contracts in the sphere of capital construction as a mechanism for quick transactions. A smart contract is a legal form of obligatory relations in the sphere of capital construction, a special means of forming and expressing the will of participants aimed at creating the desired legal consequences. The use of smart contracts will allow developing and simplifying the interaction of participants in the construction process itself, increasing their level of trust, and accelerating mandatory procedures.
The introduction of digital technologies into many economic processes is changing the functioning principles of many government institutions. This process requires regulatory regulation of newly emerged economic relations and their proper registration and legal protection. The issues of developing information relations in the sphere of turnover of the Central Federal District are related to economic, political, social and other factors that are taken into account in strategic planning, including the national security of the Russian Federation. As part of the study, a comparison of the legal regimes of the CFD turnover using the DLT system was carried out, the legal regimes of digital currency circulation and cryptocurrency circulation as a type of CFD in developed countries were analyzed.
Relationships involving blockchain organizations are largely governed by special rules that form the lex cryptographia. This regulatory framework is represented by the code of smart contracts and blockchain protocols. Regulating the legal status of digital legal entities, it acts as a local legal act, and in the field of private international law, as a supranational, conditionally autonomous legal or sub-legal system. In the first case, the lex cryptographia can be classified as a “third” legal order, developing alongside the international and domestic legal systems. In the second case, it is a system of rules that operates solely within the applicable legal order, based on the principles of autonomy of the parties’ will and freedom of contract.
Although smart contracts are currently realized in a limited scope around virtual assets, the blockchain characteristics of transparency, immutability, and self-enforcing capabilities hold significant value—especially in real estate transactions—as a way to overcome the limitations of traditional real estate transaction systems, such as double selling and duplicate registration, while improving efficiency. For these reasons, several countries have implemented blockchain technology in their real estate registration or recording systems as well as in smart contracts, and are actively operating them. We also need to identify the pros and cons of these operations and utilize blockchain-based smart contracts for real estate transactions. Under current domestic law, introducing measures to digitize real estate transactions using blockchain technology presents several legal challenges. Key issues include how to address the legal validity of smart contracts, the valuation of tokens, compliance with requirements for the transfer of property rights, the legal effect of public registration, and potential conflicts with data privacy obligations. Therefore, measures to promote smart contracts must be established through a thorough review of their consistency with existing legal frameworks. First, to prepare for the activation of smart contracts, measures to ensure regulatory flexibility—such as standard trading rules that minimize post-contract modifications—must be established, along with efforts toward technical standardization. Furthermore, if smart contracts are introduced, attempting to transition the real estate registration system to a blockchain based on its core purpose is the ultimate way to resolve the issues of the existing registration system. Legislative discussion requires establishing legal grounds to grant in rem effect to the digitization and embodiment of real assets, as well as drafting a new registration system to recognize blockchain-based registration records as valid registration for the creation and transfer of real rights. Additionally, relevant legal frameworks must be revised to ensure that the operation of blockchain does not conflict with personal information protection obligations. As blockchain technology—a core domain of information and communication technology, alongside AI—expands beyond the socio-economic sphere into daily life, a more advanced discussion is needed regarding the distinct functions or roles smart contracts based on it will play at this current stage.
The article examines the concept of legal settlement finality as applied to two fundamentally different payment instruments — decentralized cryptocurrencies and central bank digital currencies (CBDCs). The author analyzes the absence of a statutory definition of settlement finality in Russian financial law, compares the approaches of Russia, China, India and the UAE, and studies judicial practice and doctrine. Based on a comparative legal analysis, an original definition of the legal finality of digital settlement is proposed, and liability regimes for payment process participants prior to transaction completion are differentiated in relation to cryptocurrency P2P transactions and CBDC operations.

The expansion of blockchain technology and the evolution of digital platforms have led to the emergence of new concepts in contractual relations, of which "smart contracts" are among the most significant. These contracts are designed as blockchain-based computer programs that execute the terms of the parties' agreement in the form of digital codes and enable the automatic performance of obligations without the need for traditional intermediaries. Such features have increased the speed, transparency, and efficiency of transactions. However, the introduction of this technology into the field of contract law has raised fundamental questions regarding the legal nature, validity, and enforcement of such contracts in various legal systems, particularly those based on classical traditions. The aim of this research is to elucidate the legal nature of smart contracts and analyze the challenges of their enforcement in the Iranian legal system. The research method is descriptive-analytical, and data have been collected through library studies and the examination of domestic and international legal sources. Additionally, with a comparative approach, some legislative experiences of other countries in this field have been examined. The findings indicate that, despite technical differences, smart contracts can be analyzed within the framework of general contract rules. The principle of party autonomy and Article 10 of the Civil Code provide the capacity to accept this type of contract, and the Electronic Commerce Law, by recognizing data messages and electronic signatures, has established a basis for the validity of digital transactions. However, challenges such as ascertaining the true intent of the parties, determining liability for technical errors, and the conflict between the immutability feature of blockchain and institutions such as rescission and mutual rescission persist. Accordingly, the formulation of supplementary regulations, the development of legal infrastructure, and the enhancement of specialized knowledge appear essential for the safe and effective utilization of this technology.
This study examines the current state of digital asset auditing and proposes a clearer future vision through a systematic review of relevant literature and prior studies. It highlights the fundamental differences between digital and traditional assets, explains the classification of digital assets and their close association with blockchain technology, and analyzes the existing accounting and auditing frameworks considering international standards and provides a brief overview of the status of Egyptian legislation. The study also discusses the evolving role of auditors and the main stages of the audit process in the digital environment. The findings indicate that rapid digital transformation requires the development of advanced auditing standards and methodologies, and that the adoption of data analytics, smart contracts, and continuous auditing, together with enhancing auditors’ technical and professional competencies, contributes to improving audit quality, transparency, and risk management related to digital assets.

Cryptocurrencies have emerged as a prominent asset class characterized by rapid price fluctuations, growing institutional participation, and continuing debate over whether their price movements are random or predictable. This study examines the randomness and weak-form market efficiency of the top ten cryptocurrencies by market capitalization—Bitcoin, Ethereum, Tether, Binance Coin, XRP, USD Coin, Solana, TRON, Dogecoin, and Hype liquid—using daily closing price data from April 2016 to March 2026 (subject to data availability for each coin). Daily log returns were tested using Descriptive Statistics, the Jarque–Bera test of normality, the Wald–Wolfowitz Run Test, and the Autocorrelation Test. The results show that daily returns for all selected cryptocurrencies are non-normally distributed, exhibiting excess kurtosis and skewness. The Run Test results indicate that seven of the ten cryptocurrencies—Bitcoin, Ethereum, Tether, Binance Coin, XRP, USD Coin, and Dogecoin—do not follow a random walk, while Solana, TRON, and Hype liquid exhibit randomness consistent with weak-form efficiency. However, the Autocorrelation Test reveals strong positive serial correlation across all ten cryptocurrencies, indicating that the market falls short of weak-form efficiency. The study concludes that the cryptocurrency market provides mixed and largely inefficient evidence with respect to the Random Walk Hypothesis, implying that historical price information may retain some predictive value for investors.
Supplementary appendix to the article "Digital Cash and the Governance of Payment Finality." It contains material displaced from the main text for length, referenced at the corresponding points in the article, and forming no part of the manuscript word count. The appendix documents in full the evidence that claims for digital cash treat technical irreversibility as legal finality, with the passages and page references from Böhme, Christin, Edelman and Moore (2015), Cong and He (2018), De Filippi and Hassan (2016), Kiviat (2015), Atzori (2017) and Politou, Casino, Alepis and Patsakis (2019), together with the passages in which several of those authors qualify or abandon the claim. It further sets out the argument that append-only recording does not entail unrecoverable entitlement: the regulatory history of write-once, read-many electronic recordkeeping under SEC Rule 17a-4 and its 2022 amendment; the accounting mechanics by which a chargeback operates as a contra entry rather than an erasure; the equivalence between that mechanism and reversal by subsequent transaction on a distributed ledger; and two limits on the argument, being value irretrievable because no person holds the key, and records whose own existence is the wrong, as with personal data subject to an erasure right.

This article provides a comprehensive analysis of the treatment of digital assets in insolvency. Given that cryptoassets can be the subject of various transactions—including purchase, sale, custody, and lending—understanding their nature and implications in insolvency is relevant for any firm, not just cryptoexchanges. The article begins by offering a general overview of the world of cryptoassets. It then examines the nature of cryptoassets from accounting, financial, and legal perspectives. While much of the literature on insolvency and cryptoassets has primarily focused on the analysis of whether cryptocurrencies constitute property of the estate, this article explores additional issues, such as the treatment, role and rights of tokenholders in insolvency, the initiation of insolvency proceedings by cryptolenders, and the valuation, recovery, and realization of digital assets in bankruptcy. Such analysis is conducted from a comparative perspective, examining how jurisdictions around the world have addressed some of those issues and how cryptoassets have been used to engineer innovative solutions in restructuring agreements.

Cryptocurrency markets are highly volatile, nonlinear, and affected by several internal and external market factors, making price forecasting a challenging task. Accurate cryptocurrency price forecasting can support investors, traders, and financial analysts in making informed decisions. This research paper presents a comparative analysis of machine learning and deep learning models for cryptocurrency price forecasting using historical Aave (AAVE) cryptocurrency data. The dataset consists of 275 records and 10 features, including Date, High, Low, Open, Close, Volume, and Marketcap. The Close price is selected as the target variable, while High, Low, Open, Volume, and Marketcap are used as predictor variables. Five models are implemented and compared: Linear Regression, Support Vector Regression, Random Forest Regressor, XGBoost Regressor, and Long Short-Term Memory. The models are evaluated using Mean Absolute Error, Root Mean Square Error, Mean Absolute Percentage Error, R-squared score, and directional accuracy. Experimental results show that the LSTM model achieved the best performance with the lowest RMSE of 2.74, MAE of 1.78, MAPE of 3.91%, and R-squared score of 0.965. The results indicate that deep learning models, especially LSTM, are more suitable for capturing temporal dependencies and nonlinear patterns in cryptocurrency price data.

This study aims to identify the extent to which a country's level of governance implicitly determines and encourages the use of cryptocurrencies, and the main elements associated with the use of alternative currencies to traditional ones. The methodology used is a descriptive analysis of the variables, an econometric analysis through an ANOVA, and the application of a truncated regression model, which aims to bring the research closer to the possible correlation between governance indicators and the rate of adoption of cryptocurrencies. The study concludes that countries with low levels of governance are directly related to the greater adoption of cryptocurrencies. To the best of our knowledge, this study is the first to analyse the relationship between cryptocurrency adoption and institutional governance by comparing two regions with different levels of development. The research is limited by the existence of other factors that influence the analytical framework of cryptocurrency adoption, but the availability of data has allowed the present study to focus on governance aspects. Now, despite the fact that the governance indicators present a global analysis in terms of their measurement, the relevant aspects of each country are not specified. The adoption of cryptocurrencies in some countries may not be strongly related to governance aspects but rather to the friendly regulations that have been implemented.
Cryptocurrency has emerged as one of the most significant developments to accompany the digitization of global finance, and its footprint in India has expanded rapidly despite an unsettled regulatory environment. This paper examines how Indian investors perceive the opportunities and risks associated with cryptocurrency and blockchain technology, and evaluates whether their level of awareness shapes that perception. A structured questionnaire survey was administered to 158 respondents drawn from different age groups, educational backgrounds, occupations, and income levels in Karnataka, and the resulting data were analyzed using percentage analysis, frequency distribution, and the Chi-square test of independence. The findings indicate that a large majority of respondents, particularly those aged 21-30, view cryptocurrency and blockchain as tools capable of improving transparency, financial inclusion, and entrepreneurship, while simultaneously expressing concern over price volatility, cybersecurity threats, and unclear taxation rules. The Chi-square test confirmed a statistically significant association between investor awareness and perception of cryptocurrency (calculated value 19.41 against a critical value of 9.488 at 4 degrees of freedom and the 5 percent level of significance), leading to rejection of the null hypothesis. The study concludes that a clear, balanced regulatory framework combined with investor-education initiatives would allow India to capture the innovation potential of digital assets while containing the risks associated with their adoption.
This article is devoted to the general legal characteristics of smart contracts as a means of disposing of digital assets. Smart contracts are a key mechanism for transferring digital assets, but their legal regime remains controversial and unexplored. The main goal. To make a general civil law qualification of smart contracts as a special form of concluding transactions by order of the Central Bank and to justify their recognition as full-fledged legal means of achieving a legal result. The problems under consideration are the differentiation of the IC from related legal phenomena: computer programs, methods of securing, executing and concluding a transaction. The methods used are: formal-legal, comparativelegal, historical-legal, systematic. Conclusions. The IC is a special digital form of the transaction, which has the highest degree of reliability and accuracy of recording the will of the parties in the presence of objective guarantees of its execution.
The growing presence of institutional capital in crypto asset markets has reopened the debate on whether Bitcoin and similar digital assets can act as safe havens, the way gold or sovereign bonds have been built historically. This thesis tackles that question with a quantitative framework rather than the qualitative arguments that dominated the early literature. The dataset covers November 2019 to May 2026 (2,380 daily observations for Bitcoin, 2,381 for the full asset universe). I fit GARCH-t and EGARCH-t models to capture conditional variance, apply Extreme Value Theory to isolate the tail directly, and run Monte Carlo simulation to estimate capital requirements over 30-day horizon.
Cryptocurrency's convenience is a convenient truth — granted here in full, with receipts. A permissionless ledger settles across borders without account approval, banking hours, or correspondent chains; Nakamoto designed exactly that, on purpose. The correction is that the convenience and the danger are the same property: what makes the transfer fast and unstoppable is that it is final — no chargeback, no administrator, no undo. Institutions can price that trade. A person cannot, and the proposal is that the rational personal policy is a wall, not a judgment call. Offered as a proposal, not a result.

This chapter traces the intellectual and technological lineage of Bitcoin and digital money. While Nakamoto’s white paper launched Bitcoin, its roots extend through decades of economic theory, cryptographic innovation, and activist movements. We examine how the Austrian and Chicago Schools of Economics provided a framework for stateless and non-inflationary money, and how Cypherpunk ideals shaped the push for privacy and decentralization. The chapter reviews early experiments with digital currencies such as DigiCash, b-money, and e-gold, highlighting the technical shortcomings, regulatory battles, and user adoption barriers that prevented their success but furnished essential building blocks for Bitcoin. We then contrast the classical financial attributes of money—medium of exchange, unit of account, and store of value—with additional digital requirements such as offline spendability, identity-less spendability, and fungibility. Finally, we show how Bitcoin resolved the long-standing double-spending problem without a central authority through Proof of Work, situating it as both a culmination of earlier efforts and the starting point for a new era of cryptocurrencies.
Digital assets, a broad term encompassing crypto-currencies, tokens and digital representations of value, have transformed the financial landscape over the past decade. Ghana has transitioned from an unregulated crypto-currency environment to a structured, licensed digital assets space following the passage of the Virtual Asset Service Providers (VASP) Act 2025 Act 1154. Unlike traditional assets, digital assets exist exclusively in electronic form and are secured through cryptographic techniques, most notably blockchain technology. Bitcoin, Ethereum, and other crypto-currencies serve as prominent examples, alongside digital tokens used in decentralized finance (DeFi), security tokens, and stablecoins. They may serve a variety of functions, including use as a medium of exchange, for investment, or as a means of accessing goods, services, or applications within specific ecosystems. These assets include crypto-currencies, tokens, stablecoins, and other blockchain-based instruments. Global digital assets represent any item of value securely stored and managed via distributed ledger or blockchain technology. Encompassing cryptocurrencies, stablecoins, tokenized securities, and non-fungible tokens (NFTs), the sector has rapidly expanded into mainstream finance, revolutionizing global payments, portfolio diversification, and record-keeping. This article discusses the challenges and opportunities of digital currencies and the way forward. This research shows that digital currencies have advantages like making transactions faster, cheaper, and more accessible and also reveals a lot of disadvantages like creating major risks concerning compliance with regulations, cybersecurity, and potential impacts on monetary policy. The review emphasizes the necessity for robust regulatory frameworks for digital assets. It supports both innovation and stability for the digital currencies. It suggests that policymakers and financial institutions should adapt to changes and face the challenges by integrating digital currencies with existing systems. Overall, this review highlights the potential of digital currencies to transform finance. It also stresses the importance of focusing on the challenges they pose to ensure they can coexist successfully with traditional financial systems. As digital currencies evolve, the Ghanaian traditional financial sector faces pressure to adapt, with CBDCs, in particular, being explored as a secure, regulated alternative to volatile crypto-assets. nThe findings revealed that the central bank must adopt robust regulatory and licensing frameworks must align with Virtual Assets Service Providers (VASP) (Act 2025 Act 1154) by enforcing strict licensing for exchanges and custodians while adhering to AML/CFT (Anti-Money Laundering) directives. Also, the Bank of Ghana and the Securities and Exchange Commission must develop a comprehensive public education programme on the digital assets in the financial ecosystem. Given the novelty of the trend of criminality in the digital asset space, the establishment of specialized cybercrime courts to be presided over by judges, proficient in digital law and cybercrime would be of immense benefit. The mandate of such courts could be to expedite trials and ensure thorough adjudication of complex cyber cases. This would have the combined effect of empowering the Ghana Police Service and Cyber-Security Authority to fully invest time, money, and human resources towards the investigation of cybercrime, as well as serve as a deterrent for criminal elements, ultimately protecting our citizens and providing justice for those seeking redress.

A smart contract is more than a technical phenomenon; it raises legal questions about intent, transaction form, and obligation performance in a digital environment. Kazakhstani law, including the Civil Code and the Law on Electronic Documents, provides a basis for digital tools in contracts, recognizing electronic forms and the principles of freedom of contract. AIFC law further validates automated systems. However, the lack of a conceptual definition in civil legislation creates challenges for public law. This article argues that smart contracts should not be viewed as standalone contract types but through a functional approach: as either a form of expressing intent or an automated performance mechanism. Special focus is placed on criminal proceedings. The authors demonstrate that the absence of a clear definition complicates distinguishing civil torts from cybercrimes and hinders the use of code as evidence or the seizure of digital assets. The core issue is the discrepancy between traditional civil law constructs, blockchain logic, and current procedural evidentiary standards in Kazakhstan.
