Smart Contract Design for a Bidding-based Supply Chain System built on an Alliance Blockchain

With the development of marketing, the bidding transactions among enterprises become more and more frequent. The traditional supply chain system cannot meet the needs of enterprise operation, due to the problems like inefficient information sharing, low collaboration, and huge consumption of human resources. To deal with the above problems, the emergence of blockchain technology provides a promising solution. In this paper, we employ an alliance blockchain architecture to realize a bidding-based supply chain system. Specially, we design a smart contract with reasonable contract interaction rules for the whole process a bidding transaction, with two specific functions, i.e., risk early warning and intelligent bid evaluating. In addition, a real alliance blockchain is implemented based on the Hyperledger platform, to validate the feasibility of our designed smart contract.
