Traceable and Privacy-preserving Blockchain System Architecture for Remanufacturing Reverse Supply Chain

When the remanufactured product is sold to the consumer, the most concerned things for consumer should be the quality of the remanufactured parts used for production. In order to track the data information of quality for remanufactured product, new traceable and privacy-preserving blochchain system architecture for remanufacturing reverse supply chain (RRSC) is introduced in this paper. In the proposed solution, all the data of product and transaction are uploaded to InterPlanetary File System (IPFS). The hash of the data is written to the blockchain. By the help of smart contracts and encryption algorithm, the presented system achieves the traceability of key data for remanufactured products and parts. Some performance analyses show that the suggested system can guarantee the reliability of data in remanufacturing reverse supply chain management, and has actual application values.
