Transparent Management of Engineering Supply Chain Based on Blockchain

The digital economy's rapid growth has led to complex interactions among information flow, logistics, and capital flow in engineering supply chain management. Blockchain technology, with its decentralization, immutability, and full-process traceability, offers a new approach to enhancing supply chain transparency and cooperation efficiency. Common issues in engineering projects, such as information silos, data tampering, and opaque processes, significantly impede trust-building among participants. This paper explores the mechanisms and technical pathways of blockchain in improving supply chain transparency. By analyzing existing models and case studies, it identifies limitations and boundaries of current industry solutions. An innovative blockchain-based transparent management framework is proposed and validated through process modeling and virtual data. Results indicate that this framework can positively impact data transparency, protect stakeholders' rights, and foster supply chain cooperation.
