The study examines the transformation of scientific views and approaches to the problem of expediency and necessity of legal regulation of public relations, emerging from the evolution of the world system of public electronic resources in the transmission of information and Internet data from Web 1.0, Web 2.0 to Web 3.0. The stages of formation of the role and place of electronic jurisdiction in public relations are also investigated. Legal regulation of modern relations in virtual and augmented reality environments with the use of Web 3.0 technologies is not available today. At the same time, there are precedents for the application of certain provisions of analogue law to address legal uncertainties in the virtual environment, such as establishing ownership of virtual non-property assets, buying/selling of virtual non-property assets, liability for misappropriation of virtual non-property assets, etc. Obviously, the problem of legal regulation by the rules of analogue law in the virtual environment cannot be fully addressed. The solution to this problem is possible by creating a comprehensive e-jurisdiction and developing the Metaverse Grand Charter of Laws to regulate public relations in the meta-universe and to establish new branch of e-law. Given the urgency of the problem, the model of e-jurisdiction Grand Charter of Laws Metaverse is proposed. The model of complex electronic jurisdiction of Metaverse will allow to create basic conceptual apparatus, doctrinal and normative and legal concepts, to define objects and subjects of legal relations in Metaverse, to establish the basic forms of legal relations and mutual relations in Metaverse. This, in turn, will be the basis for reforming analogue legislation, partial interoperability in the digital environment and the development of new regulations in various areas of law and will stimulate the establishment of new e-jurisdiction. The study proposes the construction and basic elements of electronic jurisdiction, mechanisms for the separation of electronic offences and interaction with analogue jurisdictions. E-jurisdiction of the Metaverse Grand Charter of Laws will provide legal regulation of public relations both directly in Metaverse and in public relations related to the analogue and electronic world.

Scientific and technological revolution 4.0 (The Fourth Industrial Revolution) has created a huge window of opportunity for a variety of creative technologies. At the same time it launched the emergence and development of modern social relations in the electronic space - the metaverse. In fact, today all the prerequisites for the scientific and technological revolution 5.0 and social revolution 5.0, which radically changes the role of human in the social structure, while changing the social structure, creating new social groups, social institutions, electronic ecosystems and metaverse. Modern social relations in the electronic space are multi-vector and can be divided according to the variety of objects, subjects and characteristics of the relationship between them, namely: the subjective and object basis of identification of social relations. Thus, the subjective basis for the identification of social relations is the social communities of people, and the object one is information and communication technologies and its products. Legal science is a social science, as it performs gnoseological and heuristic functions that determine the direction of scientific research and scientific predictions, studying the relations between people, groups of people, people and state institutions. The results of research are practical improvement of legislation on a scientific basis, development of draft normative legal acts, scientific examinations, etc.However, the current practice indicates that modern laws are created very slowly, without necessary and sufficient detaliztion of terms and basic concepts.It is difficult to overestimate the correctness, accuracy and consistency with the current legislation of definitions of legal terms. Unfortunately, the current legislation is unable to regulate public relations, which are rapidly evolving in the electronic space using digital technologies, artificial intelligence, Internet of Things (IoT), digital identity, digital avatars and other technologies, especially those that may restrict human rights and freedom. In fact, along with the creation of new social relations in the metaverse, it is necessary to create an electronic jurisdiction - the scope of application of opportunities by the subject of competence or the sphere to which the right applies.The author’s definitions "metaverse (cyberspace)", "electronic avatar", "electronic personality", "electronic jurisdiction", "cybercrime", "kidnapping of electronic avatar or electronic personality", "artificial intelligence" and "neural networks" are proposed in the article.Six postulates of the main directions of development of social relations with the use of technologies of the metaverse, artificial intelligence, artificial neural networks, robotic systems, medical and military lost products and devices are formed.Proposals for the creation of a comprehensive electronic jurisdiction, conceptual and categorical apparatus, definition of subjects and objects, rights, duties and responsibilities in the metaverse and in the use of artificial intelligence technologies, artificial neural networks, robots, etc. are provided.

The Scientific and Technical Revolution 5.0 and WEB 3.0 technologies create conditions for the renovation of various forms of social relations with the use of virtual and augmented reality technologies in the metaverse. According to the proposed theory, the legal regulation of social relations in the metaverse requires the development of a comprehensive electronic jurisdiction based on the latest basic legislation. The formation of legal regulation of the metaverse is a prerequisite for the need to form an electronic jurisdiction of the metaverse, which will include sectoral Metaverse Codes. The metaverse, as the electronic society of the future, does not yet have clear legal boundaries, and the task of scholars is to predict and outline with sufficient certainty the future contours of legal authority for virtual environments. Today, discussions in the scientific community about the feasibility and necessity of legal regulation of the metaverse often revolve around several key issues. First, there is the question of what legal framework should be applied in the metaverse and how conflicts between different legal systems should be resolved. Second, there is a debate about whether current regulatory bodies in the physical world have the capacity to effectively regulate the metaverse through existing laws and regulations. Third, there is the question of how to deal with offences committed in the virtual environment, and whether they should be dealt with under existing tort or criminal law, or whether a separate cross-border electronic jurisdiction should be created. The regulation of social relations in the metaverse should focus on one central goal: to clearly define the status of electronic entities, subjects and objects, to establish their rights, duties and responsibilities, and to define the different types of relations between virtual entities, subjects and objects within a given metaverse, as well as between different metaverses within an electronic jurisdiction and in a cross-border context. An essential component of the Metaverse Electronic Jurisdiction is a Metaverse Model Criminal Code that will outline the norms and offences applicable to analogue, hybrid and electronic jurisdictions. This code will define the types of socially harmful acts or crimes and the corresponding criminal penalties that will be applied within the metaverse. The formation of the electronic jurisdiction of the metaverse and the development of a Metaverse Model Criminal Code is a current scientific and legal issue.

Анотація Кількість напрямів застосування технологій зі штучним інтелектом (далі – ШІ) з року в рік стрімко зростає. На сьогодні технологічне середовище, в якому створюються засоби штучного інтелекту, неоднорідне, оскільки використовує різноманітні завдання, кінцеві цілі, Big Data, що аналізуються, програмні методики, аналітичні підходи тощо. Це потребує більшої цільової консолідації як технологічних так й соціальних ресурсів держав.. У роботі проаналізовано матеріали Стенфордського університету США “Artificial Intelligence Index Report”, а також стратегії розвитку ШІ низки держав та інші пов’язані із ними документи. Розглянуті основні напрями розвитку та застосування технологій ШІ в різних країнах. Загальний аналіз стратегій розвитку ШІ різних держав свідчить про те, що суспільство і уряди країн розуміють важливість застосування сучасних інформаційно-комунікаційних технологій, в тому числі і технологій ШІ. Розгортання технологій в масштабах більших ніж локальне дослідження потребує залучення великої кількості різних ресурсів – спеціалістів у сфері ШІ, технологічних потужностей, фінансових ресурсів, законодавчого регулювання. Це можливо вирішити тільки комплексно, застосувавши плановий, стратегічний підхід до розвитку сфери застосування ШІ. Саме тому держави розробляють Стратегії розвитку ШІ, які відрізняються одна від одної як цілями так і можливостями їх досягнення. Однак всі Стратегії мають одну загальну мету – позитивну модернізацію суспільства та впровадження технологій ШІ у всі сфери життєдіяльності людини.

The paper addresses the issue of the Metaverse's territoriality and its connection with national and international law. The study provides a brief overview of hypotheses related to the territoriality of the Metaverse and its connection with national and international law. It explores the concept of electronic jurisdiction for the Metaverse amidst the general absence of a unified transnational legal system for virtual environments. The Internet and the Metaverse are increasingly subject to the reality of fragmenting into separate segments, which can have serious consequences for global security and the economy. The risks associated with the trend of "Metaverse fragmentation" or "Splinternet"—the division of the single global internet space into isolated segments governed by different rules and technical standards—are analysed. Innovatively, a theoretical model of a typical Metaverse is presented, potentially creating a cross-border "sandbox" for modeling technological processes, social relations, business, and legal regulation of virtual technologies to develop proposals for unifying the fundamental components of the Metaverse and simplifying cross-border interactions. The proposed Transborder Standard Model of the Metaverse is an abstract representation of systems used to understand, predict, and explain the behaviour of a complex of systems known under the generalised name Metaverse. This model is characterised by a specific structure composed of modules or ecosystems that functionally differ in purpose and structure and are not connected by similar features. However, their combined application ensures the functionality of virtual environments, and their legal regulation, and can serve as the basis for electronic jurisdiction.

Blockchain-based cryptocurrency markets present unique analytical challenges due to their decentralized nature, continuous operation, and extreme volatility. Traditional price prediction models often struggle with the binary trade execution problem in these markets. This study introduces a confidence-based classification framework that separates directional prediction from execution decisions in cryptocurrency trading. We develop a neural network system that processes multi-scale market data, combining daily macroeconomic indicators with a high-frequency order book microstructure. The model trains exclusively on directional movements (up versus down) and uses prediction confidence levels to determine trade execution. We evaluate the framework across 11 major cryptocurrency pairs over 12 months. Experimental results demonstrate 82.68% direction accuracy on executed trades with 151.11-basis point average net profit per trade at 11.99% market coverage. Order book features dominate predictive importance (81.3% of selected features), validating the critical role of blockchain microstructure data for short-term price prediction. The confidence-based execution strategy achieves superior risk-adjusted returns compared to traditional classification approaches while providing natural risk management capabilities through selective trade execution. These findings contribute to blockchain technology applications in financial markets by demonstrating how a decentralized market microstructure can be leveraged for systematic trading strategies. The methodology offers practical implementation guidelines for cryptocurrency algorithmic trading while advancing the understanding of machine learning applications in blockchain-based financial systems.
