Abstract
In recent times, supply chain management has required end-to-end traceability from material acquisition to manufacturing and delivery due to its dynamic and complex nature. Despite these demands, current centralized supply chain models exhibit three critical weaknesses: they are susceptible to forgery, operate inefficiently, and lack transparency among stakeholders. To address these limitations, this paper proposes a multichain-based decentralized framework that connects all major participants in the supply chain life cycle within an interoperable, permissioned blockchain network. In this framework, blockchains are isolated according to their functional roles, such as manufacturers, suppliers, and distributors, while remaining coordinated through a secure main network. The proposed solution provides three key benefits. First, the immutable nature of blockchain ensures that data records cannot be tampered with, thereby enhancing integrity. Second, permission-based data sharing increases trust among stakeholders by enabling controlled transparency. Finally, the architecture improves operational efficiency by distributing workloads across specialized chains. Experimental results and optimization analyses demonstrate a significant increase in scalability, transparency, and overall performance compared to conventional systems. This study contributes to the development of next-generation supply chain management systems that achieve a balanced integration of security, scalability, and operational effectiveness. © 2025 IEEE.
