With the increase of web users and applications with real time requests, the ability to identify, track and trace elements of a product as it moves in the supply chain is deemed necessary, and for many industries is even mandated by national or international regulations. Traceability presupposes the integrity and transparency of data that is saved and shared. This is a problem for current technologies, as there are many examples with tampered data and database vulnerabilities that resulted in serious implications and data loss. A solution to this problem can be the decentralization of the system, which will remove the central point of failure. To that effect, blockchain or DLT technologies, an emergent technology that enables the decentralization of a network can be used, by implementing a trustless model to achieve it. Blockchains are tamperproof and transparent, which means that by exploiting blockchain characteristics, traceability can be improved. A model that describes the decentralization process of the supply chain traceability part has been developed for this paper and is later evaluated and compared with the traditional system.
The concept of “digitalization” came into use relatively recently, but in many respects the further development of the Russian economy will depend on it. Design of conceptual approaches and practical algorithm for adaptation of new technologies to the functioning peculiarities of the financial system is of great importance for ensuring competitive advantages of Russia, including those at the international level. The article presents the prospects for applying modern technologies in the activities of state audit institutions, which are designed to ensure financial stability and contribute to the formation of a solid foundation for the economic growth of the country. The purpose of the research is to identify the prospects for automation of control procedures, taking into account the level of development of modern technologies to prevent violations in the financial sector. In the process of research, general scientific empirical methods were used: observation, comparison, collection and study of data; analysis and synthesis, a method of scientific abstraction. The chosen approach allowed to ensure the reliability and validity of the conclusions drawn. According to the results of the research the prospects for using the national accounting digital unit in the purpose of the control are outlined; the technological possibilities and legal restrictions of creation of the state distributed ledger technology are revealed; the system for assessing risky transactions that could lead to financial violations is proposed; key characteristics of the system of conducting decentralized accounting are formulated; the expected result of the implementation of the proposed models of automation of control procedures in the Russian practice is assessed. The authors have proved the expediency of creating a state distributed ledger technology for financial control purposes. The expected result of the implementation of these proposals is estimated as more than 50% of the annual violations identified by the state audit institutions.

In the course of the research, we identified seven risk groups, analyzed their influence, and formulated possible measures of the risk mitigation. For initial coin offerings projects, we formulated a special risk-assessment scoring system based on a 100-point scale. Investment risks (volatility) were one of the main issues. The only effective option of risk-management here is risk aversion - the refusal of any interaction with the cryptocurrency market. On the other hand, traditional risk management method of diversification has proved its worth and viability on empirical studies of portfolio investments. The portfolio should not be mostly “crypto” but rather it should also consist of traditional assets. It is necessary to consider the opportunity to quit the cryptocurrency market for a short period of time, to prevent the harmful consequences of dramatic price shifts.

Modern financial technologies, in particular cryptocurrencies, penetrate deeper and deeper into the life of the modern world and the Russian society. The spread of cryptocurrencies in almost all areas is promoted by the following advantages: anonymity of payments, low commissions, and the inability to restrict the owners’ access to their funds. The use of cryptocurrencies is not limited to the banking and medical areas, insurance and services industries. Some experts suggest the creation of cryptocurrency as the single currency of the Eurasian Economic Union. Today this issue is only being discussed, but the advantages and a wide spread of cryptocurrencies prove that they can become one of the possible solutions in the currency agreement of the EEU being developed. To assess the prospects of using cryptocurrencies in the Eurasian Economic Union, it is necessary to analyze the prerequisites of cryptosystems, as well as to study the history of their development. The purpose of this article is to make a comparative analysis of cryptocurrencies on the EEU market in terms of possible use of the cryptocurrency as a supranational means of payment. The article considers the prerequisites of cryptocurrencies. Features of the currently most popular cryptocurrencies are analyzed. Possibilities of using them as EEU supranational payment means are estimated. Directions of the cryptocurrencies development on the EEU market are studied.

Accordingly, the objectives of the research are: to identify the main directions and problems of the introduction of automation, to study the current state of the labor market in the world, to consider the Blockchain technology and its advantages in various fields.Methods of research. Dialectical method of scientific knowledge was applied in the research of the role of automation, the computational and analytical methods of observation, measurement, analysis and comparison of indicators characterizing unemployment in the world.Results. At the moment, the main problems of the implementation of automation are the institutional and legal norms, including the uncertainty of responsibility in the case of the event. In the process of economy and industry digitalization Blockchain technology is actively used – as one of the areas of automation and digitization tool of economic and technological processes. Blockchain remains an experimental technology – many problems of its use have not been solved yet. The uniqueness of the Blockchain lies in the immutability or irreversibility, which is guaranteed by the cryptographic protection system. The authors show that the new ways of using the technology are being developed: banks, payments and money transfers, cyber security, education, voting, car leasing and sale, network technologies and the Internet of things; insurance, forecasting, car sharing, document flow.Summary. On the basis of the conducted research, the authors propose to use Blockchain in the document flow in the Universities, where in particular, it is possible to solve the problem of the teaching staff and students reporting. By developing the system of authorization of the teaching staff reporting at the University on the basis of the Blockchain technology, it is possible to identify and verify qualitatively and to generate scientific reports faster within the structural units and Universities as a whole.
Blockchain is one of the most popular topics for discussion now. However, most experts still see this technology as only part of Bitcoin, other crypto-currencies or money transfer systems. Often, new solutions, proposed by young researchers, are blocked by reviewers, only because these solutions can not be used for Bitcoins. However, Blockchain technology is more universal and can be used also in other areas, for example, in IoT, WSN and mobile devices. This paper considers the implementation of Blockchain technology in sensor networks as an element of IoT. The concept of "Rolling Blockchain" was proposed, which can be used to build WSN with the participation of Smart Cars, as nodes of the network. The order of block formation and structure in the chain is proposed and a mathematical model is created for it. We estimate the optimal number of WSN nodes, the number of connections between nodes, for specified network reliability values, was performed.
Cyber-physical systems (CPS), robotics, Internet of Things, information and communication technologies have become more and more popular over the last several years. These topics open new perspectives and scenarios that can automate processes in human life. CPS are aimed at interaction support in information space for physical entities communicated in physical space in real time. At the same time the blockchain technology that becomes popular last years allows to organize immutable distributed database that store all significant information and provide access for CPS participants. The paper proposes an approach that is based on ontology-based context management, publish/subscribe semantic interoperability support, and blockchain techniques. Utilization of these techniques provide possibilities to develop CPS that supports dynamic, distributed, and stable coalition formation of the resources. The case study presented has been implemented for the scenario of heterogeneous mobile robots’ collaboration for the overcoming of obstacles. There are two types of robots and an information service participating in the scenario. Evaluation shows that the proposed approach is applicable for the presented class of scenarios.

The concept of cyber-physical production systems is highly discussed amongst researchers and industry experts, however, the implementation options for these systems rely mainly on obsolete technologies. Despite the fact that the blockchain is most often associated with cryptocurrency, it is fundamentally wrong to deny the universality of this technology and the prospects for its application in other industries. For example, in the insurance sector or in a number of identity verification services. This article discusses the deployment of the CPPS backbone network based on the Ethereum private blockchain system. The structure of the network is described as well as its interaction with the help of smart contracts, based on the consumption of cryptocurrency for various operations.
The article presents the results of analysis of the distributed registry technology called blockchain. The analysis was performed for the possibility of using the blockchain technology in different spheres of human activity.

This paper studies the predictability of cryptocurrencies time series. We compare several alternative univariate and multivariate models in point and density forecasting of four of the most capitalized series: Bitcoin, Litecoin, Ripple and Ethereum. We apply a set of crypto–predictors and rely on Dynamic Model Averaging to combine a large set of univariate Dynamic Linear Models and several multivariate Vector Autoregressive models with different forms of time variation. We find statistical significant improvements in point forecasting when using combinations of univariate models and in density forecasting when relying on selection of multivariate models.

This paper considers the tasks of supporting the connectivity of nodes in communication networks of unmanned transport (VANET/MANET-networks). High dynamics, decentralization and absence of hierarchy in the networks of this type actualize the task of supporting the connectivity of nodes with software-configurable security services, providing the network protection. It is offered to use a Blockchain technology based system for VANET/MANET network topologyand authentication data distribution and storage. The issue of unlimited blockchain growth preventing this method from being implemented in VANET/MANET networks is considered. The existing solutions of this issueare analyzed and drawbacks are identified. A notion of blockchain with floating genesis block is introduced and its advantages over similar ideas are demonstrated thus allowing it to be used to resolve the issue of continuously growing blockchain within the systems with stalingtransactions as a whole and in VANET/MANET networks in particular.

The creation and functioning of intelligent robots coalition is impossible without the organization of an information interaction environment between them. To solve this problem, it is proposed to use the concept of cyberphysical framework, which involves the unification of physical and cyber (virtual) environments. Intelligent robots can interact with each of the environments. The paper proposes methodology of the cyber physical smart space creation for the intelligent robots’ coalition formation and functioning, based on the concept of the “blackboard” with the support of smart contracts over the blockchain technology. It provides a new approach to the distribution of sensory, computational, information-control and service tasks between intelligent robots, embedded devices, fixed service equipment, cloud computing and information resources.

Smart City infrastructures require contracts between public and private organizations collaborating in what is frequently referred to as fog computing platforms. We investigate contract provision variations from different stakeholder perspectives. Our methodology relies on complex adaptive systems theory, and we simulate different contract provision scenarios to identify patterns that emerge. The specific contract provisions we investigate in this paper are related to analytical model and data ownership paradigm variations. We find that some variations offer advantages to stakeholders that include those who participate in the smart city fog platform and those who may have ownership of smart city fog platform infrastructure.
