SYSTEMATIC ANALYSIS OF BLOCKCHAIN DATA STORAGE AND SHARING TECHNOLOGY

This article deals with a systematic analysis of blockchain technology and its application in the modern environment. The main focus is on the problems associated with distributed blockchain technology. Areas of application of technology are indicated in this article. Mathematical models and implementation algorithms of blockchain components are considered. A systematic analysis of the contradictions of blockchain technology is carried out with a brief analysis of the internal logic (coding and consensus). This work shows the prospects for the development of blockchain services based on the concept of "smart contract", which allows transactions between participants in an automatic mode, which allows the creation of decentralized, independent organizational units.These units follow their own laws and operate almost independently, implementing decentralized programs. Decentralized applications are more flexible, transparent, and secure than modern software built using traditional models. As shown, using the features of "peer-to-peer" (P2P) networks with the equality of all participants, blockchain technologies allow direct transactions with any participant of this network. It creates a processing core of "decentralized independent organizations" that should be considered as a new type of organization similar to the digital company. Blockchain-based decisions create a secure and inherently decentralized framework for processing transactions. The main advantage of the blockchain compared to other models of databases is the algorithmic implementation of management using a single protocol. In conclusion, recommendations are given for the use of the technology of maintaining a single data register in the conditions of synchronous technologies of data processing and management.
