Abstract: 【Purpose/significance】We build a supply chain information sharing model based on blockchain technology, break through
the bottleneck of information asymmetry in the supply chain transaction process, and realize the mutual trust transaction of disinterme?
diation.【Method/process】Supply chain information sharing model is proposed based on the technologies of intelligent contract, dis?
tributed ledger and consensus mechanism of blockchain. Based on the theory of design science, the system prototype is deeply dis?
cussed based on Ethereum architecture.【Result/conclusion】It deepens the practical application of blockchain technology in the field
of supply chain management, and provide a flexible and portable information sharing platform for multi-party sharing and mainte?
nance. Through the information sharing platform, supply chain enterprises can effectively reduce information asymmetry and improve
the operation efficiency of supply chain.【Innovation/limitation】The combination of blockchain technology and supply chain deepens
the application of blockchain theory in the field of supply chain management. Congestion may lead to low efficiency of the system, and
the interface between the third-party information trading platform and the system needs to be further improved.
