No full textBLOCKCHAIN – AN OPPORTUNITY FOR DEVELOPING NEW BUSINESS MODELS
No full textOver the last years, the blockchain technology has attracted the attention of both business users and IT specialists. In essence, blockchain or a chain of blocks is a distributed and decentralized database replicated across the multiple nodes of a network. Until recently blockchain has been associated mainly with cryptocurrencies, but nowadays it is revealing its serious potential as a means of replacing the business models that facilitate the operations of business organisations and the communication between them. The utilisation of the advantages provided by blockchain, however, requires their appropriate interpretations within the framework of business processes. With reference to this, the article analyses some of the main concepts and mechanisms of this technology. Special attention is paid to the interrelation of blockchain and distributed ledger (DLT) technologies, hashing of transactions and data management through consensus as well as the so called “smart contracts”. A parallel is made between the capabilities of public and private blockchain. Based on this, the study defines the fundamental blockchain characteristics and the advantages resulting from them. It is suggested that the blockchain technology offers a solution to the primary problem of trust between people in the context of global communication and ensures better transparency, reliability and security of data and business processes. In addition, the author outlines certain potential technical and business risk that have to be taken into consideration in the process of data transfer with reference to blockchain

"THE FALL OF GOLIATH": THE DISSOLUTION OF THE KNYAZ MENSHIKOV'S UKRAINIAN ESTATES IN 1721–1765
No full textThe article is devoted to the study of the dissolution of the possessions of Prince Alexander Menshikov on the territory of the Starodub and Nizhyn regiments. This process began in the fall of 1727 after the political collapse of the temporary worker, his ruin for the benefit of the Russian state and exile to Siberia. The author's attention is focused on several plans of these events. The first is regulation from St. Petersburg, which was carried out by the Supreme Privy Council, headed by the Dolgorukovs. The second is the implementation of the decrees of Emperor Peter II and the orders of local senators. Third, the long-term implications of the broad chronological scope of the study. To depict as complete a picture as possible, a number of private cases of reactions to important changes associated with the next palace coup in the Russian capital were given. This made significant adjustments to the alignment of forces among the Starodub regimental-centenary foreman, ordinary Cossacks and the Bourgeoisie.
The aim of the study is a versatile disclosure and analysis of the disintegration of Menshikov's "state" on the territory of the Hetman State.
The research methodology is based on the principles of historicism and scientific character. Historical-genetic (in tracing the formation and disintegration of the princely patrimonial system), historical-comparative (in correlating various planes of the processes) methods were applied. From the general philosophical methods, the dialectical was used, from the general logical – synthesis and analysis.
The scientific novelty lies in the actualization of the study of Russian-Ukrainian relations in the early modern period, due to the events of our time. For the first time, the author brought together and analyzed archival data concerning the final existence of Menshikov's land holdings on the territory of the hetman regiments; along with the presentation of particular cases, a general "plot" of events was formed; it is the Ukrainian context of Menshikov's expansive activities as an imperial administrator that is highlighted.
The proposed publication continues a series of articles by the author, which deals with the Ukrainian estates of Alexander Menshikov, their formation, management, relations between the prince's administration and the regimental-centenary administrations, the political and economic background of various processes due to the so-called Pochep Case.
Studying this topic, it is possible to come to such conclusions. The history of the formation and disintegration of estates belonging to Russian statesmen from Peter's entourage is a characteristic stage in the existence of the Starodub regiment at the beginning of the 18th century. It is also a symptomatic sign of the large-scale process of integration of the Hetman State into the Russian Empire. The main role in the events studied in the article was played by Prince Alexander Menshikov. He, taking advantage of his privileged position at the Tzar's court, launched an aggressive activity, the purpose of which was to form a kind of patrimonial formation with the conventional name "princely state". It is even possible to raise the question of the potential separation of the administrative apparatus of Menshikov's "state" from the general imperial vertical of power. But these plans collapsed as a result of the political defeat of the prince in the struggle for power. Due to the complexity of the problem, the process of dissolving the remnants of the former Menshikov estates in the territory of the Hetman State dragged on until the reign of Catherine II
Creating the Metaverse: Consequences for Economy, Society, and Law
No full textObjective: to define the degree of influence of such developing technological field as metaverse on various spheres of society and to identify the need for reaction on the part of law.Methods: the key method used for the research is the systemic-structural method, which allows establishing connections between various elements of the society as a complex system, analyzing the regularities generated by the spreading influence of metaverse prototypes in one sphere on other ones. Additional methods used are formal-logical, comparative-legal methods, as well as the methods of legal modeling and forecasting.Results: the practical implementation of the metaverse concept will open new opportunities for people, but will be accompanied by drastic changes in the economic subsystem of the society, in particular, the multifold growth of the share of virtual economy and structural changes in employment. The changes will also occur in the social subsystem: the social links and the education models will transform, new personal demands will occur. Changes in the economic and social spheres will entail the need to adapt law to them, in order to preserve the effective legal regulation of social relations. Also, it should be noted that the metaverse will increase the capabilities of not only people but also the artificial intelligence, for which virtual environment is actually the “natural” one. Legal norms must provide protection of a human under the increased virtual component in people’s lives, accompanied by intellectualization of the environment.Scientific novelty: the author has systematically analyzed the changes taking place in various spheres of the modern society in connection with the development of the technological field of metaverses; highlighted the key issues arising due to the said development and requiring legal solution both at the constitutional level and at the level of sector legislation; and proposed the necessary changes in legal regulation.Practical significance: the research materials can be used when preparing proposals on changes and amendments in the current legislation, as well as in pedagogical activity, in particular, for implementation of educational courses or modules related to law under digital transformation of the society
