Abstract
Supply chain management as an indispensable component in intelligent city construction has faced great opportunities with the fast development of AI, Internet of Things, big data and mobile communication. Blockchain, as a heated and promising area, features some key characteristics that make it an optimal solution to problems in traditional supply chain management and can also act as a great platform to these cutting-edge technologies. 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. System architecture and smart contracts are designed to guarantee the security enhancement from blockchain can be fully exploited. Some common and vital problems in the blockchain-based scheme are also discussed and solved, among which a data-driven credit evaluation scheme workable on chain is put forward and a cross-chain architecture is designed to make the system more secure, intelligent and scalable.
