Abstract:Industrial blockchain represents a model of deep integration between industry and blockchain technology to reconstruct industrial operation systems. Industrial enterprises can leverage industrial blockchain to enhance collaboration efficiency, optimize business processes, and build trust ecosystems. Currently, China's industrial blockchain development is in its infancy, requiring continuous exploration for technological maturity and application implementation. To unify the understanding of industrial blockchain and provide references for its integrated applications and innovative development in industrial sectors, this paper systematically summarizes the connotation and characteristics of industrial blockchain, constructing its overall architecture from four implementation levels (industry, enterprise, production line/workshop, equipment/unit) and three dimensions (key technologies, basic platforms, integration modes). Based on industry research and industrial development demands, the technical framework of industrial blockchain is proposed, with systematic discussions on its core technologies, foundational platforms, integration models, and application scenarios. Through analysis of typical cases in vertical industries, six representative application modes are identified: collaborative R&D design, precision quality control, production process traceability, flexible safety supervision, supply chain finance, and carbon neutrality digital management. On this basis, it is proposed that future development of industrial blockchain requires joint exploration from all stakeholders, with deeper penetration into broader fields and scenarios across technical, application, and industrial layers.
