Efficient Traceability Systems of Steel Products Using Blockchain-Based Industrial Internet of Things

Abstract

With the development of the industrial Internet of Things (IIoT), the existing IIoT platform has gradually formed a large-scale, heterogeneous distributed environment. How to ensure information security and achieve efficient product traceability is an urgent problem to be solved in the development of the steel IoT platform. In view of the low transparency of information traceability of current steel products and the defects of information islands, in this article the blockchain-based steel IoT quality traceability system is developed and adopted the alliance chain mode and the Hyperledger blockchain platform. Experimental tests prove that production companies, logistics, and consumers can participate in the information certification of steel products via the system. Consumers can understand the real product manufacturing process, effectively avoiding the incomplete information and low transparency in the traditional information traceability process, and effectively trace the quality of steel products. The system provides an effective scheme for promoting the transformation and upgrading of the steel industry.
