## 1 Introduction
[14] proposed a system based on a Hyperledger structure which improves the effectiveness of traceability throughout the pharmaceutical supply chain by simultaneously storing transaction information both on and off the chain to achieve secure and fast transactions. [PERSON] et al. [15] proposed a solution based on non-homogenized tokens (NFTs) for a reliable and efficient medical device traceability system through a decentralized storage system. [PERSON] et al. [16] proposed a blockchain-based reverse supply chain recycling strategy for power batteries to establish a blockchain power battery recycling platform, which improves the utilization rate of used power batteries and the transparency of the battery recycling industry chain. With the rapid increase in the variety of spare parts, the complexity of the supply chain of aircraft components leads to inefficiencies in traceability; for this reason, [PERSON] et al. [17] proposed a blockchain-based system that improves the quality of traceability data and enables secure and adequate information sharing. [PERSON] et al. [18] utilized blockchain technology to achieve steel transaction data transparency, and experimental comparisons show that the improved PBFT algorithm has some improvement in fault tolerance, throughput, and execution efficiency. [PERSON] et al. [19] proposed a vaccine supply chain based on blockchain and the Internet of Things (IoT), and the proposed system enables resilience, tracking, and tracing of vaccine distribution. [PERSON] et al. [20] developed a traceability and on-farm management system based on IoT technology which effectively calibrates irrigation and fertilization operations. [PERSON] et al. [21] developed an agile and automated traceability system based on the ISO food standard. [PERSON] et al. [22] proposed a traceability information system for obtaining, processing, and providing information about wood furniture products, which can increase consumer trust and willingness to purchase environmentally friendly products. [PERSON] et al. [23] proposed an agri-food traceability system based on a multi-chain architecture that ensures the invariance, reliability, and transparency of data along the value chain. [PERSON] et al. [24] proposed a blockchain-based method for storing agricultural monitoring data, which can ensure the privacy and security of monitoring data. [PERSON] et al. [25] proposed a blockchain-based food traceability system that can improve consumers' willingness to purchase agricultural products. However, research on incorporating blockchain technology to securely protect the data in the interaction process for information and identity resolution for each link in the whole life cycle of industrial products and then realizing information management for the whole life cycle of industrial products has not been reported so far, which is a kind of research idea worth exploring for the credible traceability of the quality of the whole life cycle of industrial products. To sum up, identity resolution plays a pivotal role in the quality management of the whole life cycle of industrial products, bridging the information barriers between different industries or enterprises and promoting the integration of information. It is also an indispensable step in realizing the intelligent manufacturing of industrial products. It is urgently needed to improve the safety and security capabilities of information storage and data resolution. With the help of blockchain technology, we can make up for the lack of an information storage and resolution process security capability in industrial product identity resolution systems so as to truly realize \"horizontal to the edge, vertical to the end\" in the whole life cycle information management of industrial products.
