Issues of Practical Application of Blockchain Technology

Abstract

Since the advent of the Internet, the blockchain technology (BT) has been recognized as one of the most explosive innovations of the early 21st century, capable of changing both financial and non-financial applications. The paper presents various interpretations of the blockchain, illustrates the process of inclusion of a new block into it, briefly discusses the issues of standardization of this new technology by organizations such as ISO and NIST, as well as introduces the basic BT notion for a transaction. The main task of this article is to give a generalized idea of the composition and structure of blocks of the blockchain, taking into account the identifier and the hash connecting each new block with its predecessor. It also provides an example of accounting and saving in a holistic and chronological form transactions in the blockchain for the case of its use in managing information security incidents in computer networks. The presented results can be extended to any subject area in which it is possible and reasonable to create a blockchain. In conclusion, the directions of subsequent research in this area are determined.
