Problem setting. Currently, there is a transition from an environment focused on obtaining a diploma to an environment that is more focused on continuing education of people. Reducing the factor of high vulnerability of users' personal data is possible due to the implementation of blockchain technology in the higher education system.

Target. To investigate the possibility of implementing a peer-to-peer blockchain network to increase the security of distributing student credentials with the possibility of personal control.

Results. A model of a peer-to-peer blockchain network is visualized. The parameters of a centralized and decentralized data processing network have been studied. It is shown that the confidentiality of data in a decentralized system (blockchain network) is an order of magnitude higher than in a centralized one.

Practical significance. Distributed registry technology (blockchain) will eliminate the storage of archives in the higher education system. Data can be stored in a single network with the possibility of quick access to them with a high level of storage reliability and information security.
