Food safety uplink data credibility measurement method based on block chain

The invention relates to the technical field of food traceability, and discloses a food safety uplink data credibility measurement method based on blockchain, and the method comprises the steps: building an on-chain member credit measurement model which is obtained through the initial credit of an on-chain member, the consensus of uplink data, and the comprehensive evaluation of a third-party quality inspection mechanism according to enterprise information; establishing an on-chain data quality measurement model, wherein the on-chain data quality measurement model is composed of a data quality attribute measurement model; and establishing an uplink data credibility measurement model, wherein the uplink data credibility measurement model is formed by constructing an on-chain member credit measurement model and an on-chain data quality measurement model by using an evidence theory. According to the food safety uplink data credibility measurement method based on the block chain, a dynamic and hierarchical food s
