摘要：

利用联盟区块链对接钢厂的智慧制造系统, 基于钢厂提供的第一手、真实、不可篡改的质保书数据, 实现钢材产成品质保书在线生成和分拆, 可向下游多级经销商和终端用户提供区块链质保书, 满足钢材交易多级流转的实际情况. 基于智能合约实现质保书数据存证、质保书权限转让、质保书履历记录等功能, 解决传统纸质钢材质保书的篡改伪造问题, 实现钢材质保书电子化, 可扫码在链上核查质保书真伪, 节省各方打印、邮寄、保存的成本. 实验证明了系统的高效性和高可用性.

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.

Key words: blockchain, inspection certificate, steel, supply chain
