Abstract: Despite heightened interest of the international and national financial institutions and enterprises of the real economic sector in distributed data storage technologies, there are very few research dedicated to the problems of assessment of blockchain platforms’ potential in socioeconomic environment and their theoretical comprehension. The existing works usually reveal either a technical side of the object of research, or normative legal aspects of applicability of blockchain technologies in national economy. The object of this article is the financial sector of national economy of the Russian Federation. The subject is the relations established between the participants of financial market based on blockchain technologies and the effects thereof. An attempt is made to fill the gaps in studying such aspects as economic and social effects of implementation of blockchain technologies into the activity of economic entities. Based on assessment of the forming effects, caused by integration of the distributed data storage technologies into the system of economic operations, the author carries out a formalized assessment and scenario modeling of the dynamics of GDP growth in the new institutional economic conditions. This research is aimed as strengthening the positions of formalized approaches towards studying the articulated scientific-practical problem on the background of overwhelming dominance of qualitative approaches towards examination of blockchain technologies.
