The aim of the article is to study the evolution of the use of blockchain technologies in the practice of different companies. The research methodology includes the use of the historical method to study the main stages of development of blockchain technologies and the study of blockchain use practices by different companies. The relationship between the stages of evolution and Tiers of Blockchain has been established: 2008-2013 (Blockchain 1.0); 2013-2015 (Blockchain 2.0); 2015-2018 (Blockchain 3.0); From 2018 to now (Generation X).

Peculiarities of practical implementation of blockchain technologies in the activity of companies of different sectors of the economy are studied. A SWOT-analysis was conducted, which revealed that blockchain technologies will undoubtedly continue to develop, affecting many industries, including public administration, retail, information technology, travel, health, education, agriculture and entertainment. One of the ways to improve the use of blockchain technologies should be: increasing the confidentiality of operations; scaling of chains of blocks; establishing compatibility between different blockchain systems; strengthening the security of blockchain operations; individual approach to the use of blockchain technologies.
