Blockchain technology is analyzed in various spheres: power-managing activities, banking sector of the economy, health care and logistics. It is supposed that the application of this technology in the election campaigns of municipal, regional and federal levels will make the struggle with electoral absenteeism more effective. Besides it will boost the electorate attendance regardless of the level of elections, thus making the electoral process more transparent. On the example of Sierra Leone, where the presidential elections of 2018 were held with the use of blockchain technology for the first time in the history, the merits of this system are demonstrated. Both positive and negative aspects of this system application are identified.
