Ever since the first block of the Bitcoin network was created, the relevance of research into the assessment of the prospects of the blockchain project is constantly increasing. Ultimately, the economics of a token will have a big impact on how it will be used, how easy it will be to build a network, and whether there will be much interest in the options of its use. The work substantiates that tokenomics allows us to determine which digital assets can be traded or exchanged for other tokens or fiats in the blockchain network. It is noted that the key difference between traditional economics and tokenomics is that the latter is written in code. The authors systematized the elements of tokenomics: supply and demand, the utility of the token, its distribution, the burn of the token, mechanism of token stimulation. The mechanism and working principles of Proof-of-Stake and its differences from Proof of Work, which consists, first of all, of reducing computing costs, are revealed. It is stated in the work that in the coming years, the development of the potential of this algorithm and the growth of the level of popularity of cryptocurrency mining based on it is expected.

Analysis, evaluate and forecast the development of foreign economic relations between Ukraine and Japan. Studies of scientific problems related to the intensification of Ukrainian-Japanese cooperation in the foreign economic sphere were carried out using critical and scientific analysis, methods of scientific generalization and systematization, induction and deduction. To predict the volume of exports of domestic products to Japan, the following adaptive methods for forecasting: Holt model, Holt-Muir model were used. Since there are significant fluctuations in the series of dynamics (imports volume), we revealed abnormal values of the series. To detect anomalous values of the series, the Irwin method is used. The obtained results made it possible to draw a conclusion about the existing trends of further growth in the volume of export and import of industrial goods between Ukraine and Japan despite the conditions of the war. The analysis and forecast of exports to Japan indicate not only the aggressiveness of international marketing of Japanese entrepreneurs but also reflects the shortcomings of Ukrainian business - cannot or does not want to focus on the production and export of labor-intensive industrial products with higher value added. Despite the localization of active hostilities, Ukraine's economic prospects remain extremely uncertain and depend on the duration of the war. In general, in order to support the export of traditional industrial goods (metal products. machinery and chemical products) to Japan, Ukraine needs to create an effective state policy of innovative development of domestic industry. The adaptive forecasting models presented in the article reproduce the dynamics of foreign trade relations between Ukraine and Japan. Unlike the existing ones, they are the most adequate forecasting tool in conditions of limited information and uncertainty. The results of the research presented in this work can be applied in practice for the analysis, evaluation and forecast of the development of foreign economic relations between the countries of the world.

With the intensification of digitalization of all processes and activities, the issue of information protection and increasing the level of cyber security is becoming important. Particular attention in this aspect should be focused on the field of queuing. The article provides a brief overview of digital transformation and data protection, which shows that the largest share is occupied by accidents of server equipment, infrastructure / network equipment, applications, data storage system equipment and cyber attacks. The authors focus on key aspects and trends related to the cyber threat landscape; argued the need to introduce new tools for biometric identification and authentication, the most promising of which is behavioral biometrics. The proposed comparative characteristic of types of behavioral biometrics allowed to define spheres of their application and to reveal the drawbacks and advantages.

The article considers the theoretical and methodological approaches to global value chains when measuring international trade. Global trends in the modern development of international trade are analysed, and the main challenges of international trade policy for Ukraine are characterised. It is established that the modern structure of the Ukrainian economy was formed under the influence of external factors. The authors propose that, over time, the influence of the global economy on the dynamics and structure of the Ukrainian economy will continually intensify. The prospects of Ukraine’s integration into global value chains are examined, and the authors found that the structure of Ukrainian exports of goods coincides with the structure of world exports only partially. Ukrainian export of goods is characterised by a low share of highly processed industrial products and a high share of low value‑added products, in particular, basic metals and agriculture and food industry products. The export of domestic high‑tech goods is constantly decreasing compared to developed countries, and its share in the world export of high‑tech goods is insignificant. To ensure the acceleration of GDP growth in Ukraine, it is important not only to increase exports, but also to increase the export of high‑tech goods.

The availability of digital technologies for a wide variety of companies opens up fundamentally new opportunities for the collection and analysis of information about markets and consumers, the implementation of marketing communications with customers and the formation of brand awareness. Digital marketing provides interaction with customers and business partners using digital information and communication technologies and electronic means. The purpose of the research is to study the features of digital marketing in the sphere of promotion of organic products based on the investigation of the experience of European Union’s countries. Design/Methodology/Approach: economic and statistical analysis and comparison; economic and mathematical method; formalization; analysis and synthesis; historical and logical methods; generalization. As a result of the study, it has been established that the development of digital marketing in the sphere of promoting organic products is in its infancy. It depends on the structure of producers, which is formed according to the principle of family farms or small farm enterprises with no more than 15 employees without a special position of a marketer. It has been proved that social networks are the main channels of digital marketing of enterprises - producers of organic products, forasmuch as they do not require additional costs to attract a specialist on marketing.
