Annotation:Currently, there is a tendency to over-promote the phenomenon of blockchain technology (BC), which is supposedly universal and has all-pervasive possibilities for revolutionary transformation of the various areas of social activity, including business and state governance. As an example, the relatively successful development of the so-called cryptocurrencies, which have already won a certain share of public relations at both the national and global levels, is given. The presence of such mass statements is explained by the fact that the description of the obvious advantages of the BС is carried out without a detailed and comprehensive risk analysis of the practical implementation of its basic concepts, including information security of the appropriate applications. The proposed work shows methods for ensuring a consensus between fundamentally distrustful users, who ensure the relative stability of cryptocurrency systems even in the absence of a centralized (state and, moreover, international) level of regulation. An appropriate classification of systems based on the BC and their features are given. Along with this, this paper focuses on the need for a thorough and comprehensive analysis of the information security risks associated with the BC use. It is shown that at the present stage of the BC systems development, they do not provide reliable user authentication, reliable system management, guarantees of secure generation, distribution and storage of cryptographic keys, guaranteed possibility of returning the values stolen by hackers, and also do not implement the principle of non-repudiation. The conclusion is made about the expediency of its further comprehensive application, based on the fact that the BC unreasonable use can cause considerable damage at the level of the whole sector of the economy. This article is a continuation of publications about the properties and features of blockchain technology.

Annotation:The transition from the information economy to the digital presents new challenges to the community related to the development of breakthrough technologies, a network of cyber-physical systems, artificial intelligence, and big data. When creating digital platforms, a number of difficulties arise: the large dimension of the digital infrastructure and its heterogeneity, poorly established information interaction between the segments, the lack of a common approach to ensuring cybersecurity and high dependence on personnel qualification and reliability of equipment.
