In the context of the continuous improvement of the modern asset management system, in view of the difficulties in breaking through the traditional logistics support concept, integrating the supply chain, and the lack of joint support force of the integrated national strategic force, this paper establishes a logistics support supply chain model by using blockchain technology. On this basis, a deeply integrated supply chain information platform is established in combination with blockchain technology, which effectively connects the basic functions such as transportation, storage, loading, handling, packaging, processing and distribution, as well as all relevant parties involved, weakening the information gap. Compared with the traditional form of logistics support concept, the military logistics support supply chain (the MLSSC) platform can improve the security of data information while eliminating the information gap through mechanisms such as timely data uploading, traceability, tamper-proof, and channel isolation. Through case analysis, the feasibility and effectiveness of the MLSSC platform based on blockchain in practical application are verified.
