description: The masters final qualifying work is devoted to research in the field of data storage through blockchain systems. The problems of using blockchain technology for the task of storing final data are described and ways of solving them are considered. The existing Proof of Works (PoW) blockchain algorithm is considered, its disadvantages are identified and a modified blockchain based on the PoW method is proposed for the task of storing final data. The review of tools for the development of a high-quality software product is carried out. As part of the work, an automated approach is proposed, which consists in using a set of self-hosted software tools for all stages of software product development. The method of interaction of client data storage applications through a decentralized I2P network is described and implemented. The proposed approach was implemented in a tool with a modified blockchain structure based on the PoW algorithm for the task of storing summary data inside a decentralized I2P network. The resulting tool demonstrates a decrease in the amount of data stored in the blockchain, which in the future will reduce the costs of using final data warehouses and their network infrastructure, and also will not allow decentralized solutions to be forced to centralize in data centers due to insufficient storage on user and mobile devices.
