MAIN MECHANISMS OF BLOCKCHAIN TECHNOLOGY IMPLEMENTATION IN DIGITAL TECHNOLOGIES APPLICATION.

Purpose. To analyze the basic principles of blockchain technology implementation, highlighting the algorithms for reaching consensus in the blockchain network to ensure its reliability; to identify key problems in the implementation of such technology and suggest ways to overcome them; to perform a systematic analysis of the blockchain technology contradictions and suggest ways to eliminate them. Methodology. The research used the basics of economic analysis of economic entities to compare their managements centralized and decentralized models. This approach showed that another wave of transformation of business and social models has unfolded in recent years, caused by the next-generation digital technologies involving the economys transition to the digital area. Revealing the blockchain technology mechanisms is based on modern databases and peer-to-peer computer networks, covering in detail the main means of contradictions, application, and implementation of blockchain technology. Findings. The main results of these studies are obtained in the digital economy. The paper shows that digital technologies open up a wide range of opportunities for different sectors of the economy. The research highlights the features and principles of distributed registry technology (Blockchain) applications. It is shown that as a decentralized data registry, blockchain technology is the most discussed and relevant topic in the digital economy. Originality. The paper further developed the main component of the digital economy, which is progressing most intensively, the distributed ledger technology (Blockchain). The paper analyzed its strengths, such as cost reduction, increased security, and transparency of transactions that attracted the attention of various sectors of the economy. The authors approach for eliminating the revealed mechanisms of contradictions, application, and implementation of blockchain technology is presented. The definition of the digital economy, digital technologies in the economy, and end-to-end digital technologies have been improved to clarify the understanding of the economic management decentralization problems. That showed that the digital economy has several subtleties associated with insufficient research and comprehension of technical implementation and flexibility. Practical value. The research results will be useful for expanding ideas about the blockchain technology implementation in different sectors of the economy, accompanied by lower costs, increased security and transparency of economic entities, and improving their economic efficiency and development in digital technologies application. The blockchain technologies implantation at the enterprises of the mining and metallurgical industry allows making the production and sales of products more efficient and transparent, and at the same time significantly reduces the human factor.
