The development of artificial intelligence in combination with blockchain features is marking a technological revolution in terms of the creation of different intelligent robots, and softbots, and more and more attempts are being made to create an artificial human who will be able to help, understand both the speech and the feelings of the real man. Regarding the implementation of decentralized artificial intelligence in institutions of higher education, there are delays in the implementation of blockchain systems for managing large and variable data. This is mainly due to some unique characteristics of the blockchain, which limit the possibility of data variability, and their updating in real-time. However, we are witnessing the implementation of intelligent softbots that are helping students in various fields. The purpose of creating intelligent robots, and in particular decentralized artificial intelligence, is not to replace humans, but to use human intelligence to create intelligent devices that, above all, will facilitate their lives and way of working. Through the paper, we will try to describe the synergy of cooperation between blockchain technology and artificial intelligence in the creation of decentralized big data management systems. We will give the greatest importance to the implementation of blockchain technology in the verification of diplomas, as very important documents that are generated by the institutions of higher education. We will give examples of the execution of the smart contract for the verification of diplomas, as well as the implementation of AI agents within the blockchain workspace that help in the testing and optimization of the smart contract. Through predictive techniques, and multiple regression, we describe an analysis of the verification of diplomas for a higher education institution within a year, taking simulations as examples.

Payments under a letter of credit are one of the forms of non-cash transactions, which is designed to meet the concerns of both the payer and the recipient of funds. Such obligations make it possible not only to perform quick payments, but also to obtain guarantee of the transfer of goods, construction or services. The advantages of this form of transactions can also be used in the implementation of blockchain technology and smart contracts, however, it requires adequate legal regulation. The aim of this publication is to consider the prospects for normative improvement of Russian legal norms in terms of regulation of both the letter of credit form of transaction and the use of information and Internet technologies in its implementation. The study conducted a comparative analysis of the subject composition and content of the “classic” letter of credit in international transactions and the initial Russian experience in the implementation of a letter of credit on the blockchain platform and the use of smart contracts. This approach, including consideration of the legislation of Russia and other countries, became the basis for the conclusion that the world community and the Russian legislator are at the initial stage of understanding this kind of public relations. In this regard, it is necessary to create unified international agreements in this area, agreed by the states among themselves, and harmonized with international standards of national law.

Block-chain technology involves a transparent, fraud resistant and decentralised mechanism that helps in enhancing transparency as well as efficiency of operations management in different sectors. In medical sector, adoption of this technology is increasing at a slow pace and bringing significant transformation in ways of providing services to clients or end customers. Block-chain technology is known to have a positive influence on enhancing quality of healthcare services through integration of several advanced protocols and algorithms for effective detection of quality issues in medicine or device supply-chain. Besides that, patient data-protection has always been a challenge that this industry has suffered from and incorporation of block-chain-technologies can help this sector to cope with this problem by enhancing encryption of confidential information of patients. During transmission or storage of patient information, there could be reciprocations or changes in this information that are done for satisfaction of malevolent needs of people. This often causes organisations in this sector to face legal obligations resulting from poor and insecure management of operations. GPOs sometimes face significant challenges in determining if providers of medicines or devices are complying with quality standards as per contracts. However, Block-chain technology has aided in ensuring security and safety of medicines and other medical equipment by allowing tracing at different levels of supply chain. Present study is aimed at analysing impact of incorporating block-chain-technologies in operations-management of medical industry. Use of secondary data-collection and thematic analysis has helped in finding positive relationship between implementation of block-chain technology and improvement in operations management in this industry.

One of the modern trends in the development of information and communication technologies that have evolved into the Internet of Things (IoT) paradigm is the progressive idea of using blockchain technology in IoT. This trend is described in a large number of modern literature sources, which point out the significant advantages of using blockchain, primarily related to decentralization, immutability, transparency and security. This allows us to conclude that the implementation of blockchain technology in IoT information and communication systems is highly relevant. However, the authors of different studies describe significant problems, including the problem of scalability of the blockchain itself, as well as the problems of energy efficiency and limited resources in IoT devices. Due to these problems, the implementation of blockchain technology in the Internet of Things is becoming a challenge and determines the relevance and feasibility of researching this topic and finding effective solutions related to the integration of two very powerful technologies in modern information and communication systems. The article presents an analytical overview of the issues of integrating blockchain technology into IoT, in particular, the use of the Proof-of-Work (PoW) consensus algorithm in IoT and the use of alternative blockchain protocols, including IOTA, Ethereum Light Client and Litecoin, which allow increasing the efficiency of performing tasks in IoT infrastructure, taking into account the limited resources of devices; existing problems and implementation methods, such as the use of light clients and proxy servers. The article also considers the feasibility of using a full blockchain node on IoT devices and ways to increase system efficiency by pre-processing data before sending it to the blockchain network. The article also highlights the problem of insufficient implementation of blockchain technology in various spheres of human life, as well as the search for the reasons for this problem. The results of the analytical review make it possible to substantiate the purpose and advantages of integrating blockchain technology into the Internet of Things, as well as to summarize the main issues and substantiate a number of tasks for relevant and progressive scientific research in the field of modern information and communication systems.
