Abstract:

This study investigates the application of consortium blockchain technology to steel inspection certificates to facilitate the issuing of trustworthy, accountable, transferable, divisible, and electronic certificates for industrial internet users. With the help of blockchain technology, steel plants provided authentic certificate data to Ouyeel. They authorized Ouyeel to produce and issue electronic inspection certificates based on the trustworthy certificate data and online business transactions for internet users. The smart contracts were developed for quality data recording, ownership transferring, certificate history, and so on. The blockchain-based steel inspection certificates were tamper-proof and could be verified by scanning the 2D barcode on the certificates. Thus, the costs of printing, mailing, and archiving for manufacturers, distributors, and end users are significantly reduced. The experiments prove the high efficiency and availability of the system through sufficient function and performance tests.
