In order to improve the credibility, availability and reliability of equipment quality information management, blockchain technology is used for management. This paper analyzes the core pain points of the current equipment quality information management, combined with the technical characteristics of blockchain, such as decentralization, tamper-proof traceability, safety and reliability, and excavates its application value in equipment information management, designs the technical architecture of equipment quality information management system based on blockchain, and conceives the application scenario of equipment quality management based on blockchain. The results show that the research has a certain reference value to improve the level of equipment quality information management.
