description: The topic of the graduate qualification work: "Implementation of a transaction registry based on blockchain technology with proof-of-state confirmation". This work is devoted to the implementation of the transaction register of student diplomas based on blockchain technology. During the implementation the current blockchain technologies and also ways of secure document storage were investigated. The technology of smart contracts was also studied. In the course of the work, using the Kotlin language, the Ktor framework and the web3j and IPFS libraries, a client-server application was developed. It runs on the Apple M1 processor. For demonstration purposes, interaction in the Firefox web browser is used. The implemented client-server application is studied from the point of view of university diploma storage security. It supports diploma storage, checking whether the student has a diploma by full name and date of birth, as well as by the unique number of the diploma itself.
