ETO (engineering to order) enterprise production is a production mode integrating product design, parts processing and finished product assembly. Its product production process is difficult to monitor in real time, and its production data is difficult to trace. To this end, taking advantage of the characteristics of blockchain, such as high security, data that was not easy to tamper with and data that was easy to trace, an ETO type enterprise production process traceability system was implemented based on the Hyperledger blockchain framework. The research results show that the traceability network has good data throughput, low data query delay and uplink delay, effectively solves the problem of inconvenient data traceability of ETO type enterprise product production process and improves data security and traceability.
