Abstract. 

The article is devoted to the development of the concept of a system that monitors potential contacts between subjects and notifies them in case of the likelihood of infection. Based on the analysis of similar projects, it is proposed and justified the choice of an exclusive blockchain as a layer for storing and exchanging data, the algorithm for fixing a contact is described in detail, and the risk of analyzing infection and information dissemination is described. Particular attention is paid to the issue of maintaining the privacy of the subjects. The described system can be used in large cities or at the federal level.
