DEVELOPMENT OF THE MODEL AND ARCHITECTURE OF A BLOCKCHAIN-BASED DATA PROTECTION SYSTEM

Abstract

This study presents the development of a model and architecture for a blockchain-based data protection system. The research focuses on addressing the limitations of traditional centralized systems, such as single points of failure, lack of transparency, and vulnerability to cyberattacks. A multi-layer architecture is proposed, integrating blockchain technology, cryptographic mechanisms, distributed storage, and access control services. The system ensures data confidentiality, integrity, availability, traceability, and accountability throughout its lifecycle. Key components include user roles, application services, smart contracts, and hybrid storage solutions combining on-chain and off-chain mechanisms. The findings demonstrate that the proposed architecture significantly enhances security, scalability, and reliability in modern information systems.
