Abstract

With the development of decentralized technologies and the increasing volume of data generated and processed, there is a challenge to ensure effective and secure information management, especially in the context of distributed systems. Traditional centralized databases increasingly demonstrate limitations in terms of scalability and fault tolerance. The paper proposes a comprehensive analysis of modern blockchain-based decentralized database technologies and examines the authentication and authorization methods used in them. The study covers seven leading systems: BigchainDB, GUN, OrbitDB, Bluzelle, Fluree, and Ties.DB, and Hyperledger Fabric. The problem statement includes current challenges in the field of decentralized data storage, such as ensuring a high level of security, scalability, and compliance with regulatory requirements. An important component of the paper is the analysis of recent research and publications, focused on the development of consensus algorithms, improvement of cryptographic methods, and integration of smart contracts into decentralized databases. Each system is examined in terms of its architecture, consensus mechanisms, and approaches to data management. The main objective of the study is to systematize and comparatively analyze existing decentralized database technologies, assess their efficiency and security, and identify promising directions for further development. Special attention is paid to security methods, particularly the use of public key cryptography, smart contracts, and distributed access control.
