The article is devoted to the development of a decentralized multichain blockchain system designed to improve the management of logistics processes. In the context of modern logistics networks, traditional solutions often face challenges of transparency, security, and scalability. This paper proposes a system that utilizes a multi-chain architecture to provide flexibility, a high degree of transparency, and control over data distributed across multiple chains. This solution provides the possibility of creating independent subchains, which allows the system to be customized for different logistics operations and customers. In addition, sections of the network can be created without losing its integrity, which has a positive impact on information security. The key element of the system is the use of the SHA-256 algorithm to hash data, which guarantees its immutability and security. The REST API is used for processing requests and integration with external systems, and WebSocket is used for real-time data exchange. Such approaches allow the system to scale efficiently, ensuring high performance even when processing large amounts of data. The paper discusses the possibilities of applying the proposed model in real logistics, including cargo tracking, inventory management, and transaction accounting.
