Abstract
Nowadays the composition and structure of the manufacturing industry supply chain have become increasingly complex. The loss and not-in-time transmission of the supply chain information have aggravated the bullwhip effect. At the same time, due to the lack of reliable information storage, the difficulties of traceability and accountability have also caused supply chain management to fall into the bottleneck. The blockchain has the characteristics of supporting distributed networking, information synchronization among nodes, digital encryption, traceable information and block content that cannot be tampered, which is suitable for use in supply chain, and can provide solution for it. In this paper, a design scheme of integrated platform for information service provided by participants in supply chain and based on Ethereum blockchain is proposed. By using Ethereum smart contracts, the common business involved in the supply chain is realized using blockchain technology, and the key information of supply chain production and circulation is stored on the blockchain to ensure the information cannot be tampered. At the same time, a reputation evaluating method based on smart contracts is used to evaluate the reputation of enterprises in supply chain, which can provide reference for supplier selection among enterprises.
