description: The subject of the master's degree thesis: "Developing a service for financial conditions approval in a public distributed ledger with confidentiality". For purpose of master's degree research, a review of approaches ensuring confidentiality of network data in public distributed ledgers was conducted. Existing solutions for the implementation of public distributed ledgers are analyzed. Requirements for the task are defined, taking into account selected methods and technologies, and architecture of the service is described. The coordination mechanism was selected to ensure reliability and fairness of approval process, and evaluation model was developed for interaction between parties. As a result of the master's degree thesis, a service was designed that allows to negotiate financial conditions using an auction based on a public blockchain with confidential transaction data. Interaction with the service is implemented by connecting to blockchain network and pre-described command line scripts. Modular and system testing of the service was carried out.
