ПРИМЕНЕНИЕ БЛОКЧЕЙН ТЕХНОЛОГИИ В КРИТИЧЕСКИХ РАСПРЕДЕЛЕННЫХ ИНФОРМАЦИОННЫХ СИСТЕМАХ: КОНЦЕПТУАЛЬНЫЕ ОСНОВЫ

Abstract

Introduction: the most promising approach to the creation of critical distributed information systems is the use of modern information technologies. In this regard, it is of great interest to study the possibilities of building systems of this class based on blockchain technology, which, unlike traditional transactional technology, involves distributed data storage with the formation of a distributed ledger. Purpose: the purpose of the research is to develop a conceptual framework for such an approach, covering the features of blockchain technology. Methods: the goal is achieved by conducting a comparative analysis of blockchain technology and transactional technology, developing an algorithm for the functioning of the system, determining the order of interaction between governing bodies and forming criteria for building a system based on blockchain technology. Results: the results of a comparative analysis showed that the introduction of blockchain technology into critical distributed information systems increases the efficiency of data collection and the availability of information resources stored and transmitted within the system. The developed algorithm for the functioning of a distributed information system based on blockchain technology contains three stages, during which, through the use of hash functions, converting the content of the transmitted document into a digital fingerprint and distributing a chain of data blocks across all network nodes, distributed data storage and complete security are ensured. Practical relevance: the considered order of interaction between governing bodies and exchange of information resources in a system based on blockchain technology demonstrated the possibility of practical implementation of this technology in a critical distributed information system and made it possible to form criteria for its construction. Discussion: as the main criteria, the coefficients of the timeliness of information exchange and the availability of information resources are proposed. To satisfy these criteria, in the search for optimal combinations of parameters for the implementation of blockchain technology, the simulation model of the functioning of a critical distributed information system based on blockchain technology should be used, which is considered as a further research direction."
