C2M order production progress multi-anchor point blockchain dynamic verification method and system for bird's nest

Abstract

The application discloses a kind of bird's nest C2M order production progress multi-anchor point blockchain dynamic verification method and system, belong to blockchain storage verification technical field.Order is split into to-be-produced unit and is assigned batch fingerprint, the temperature distribution of each production node, moisture activity gradient, time stamp and raw material batch data are collected;Process characteristic value, time sequence characteristic value and state characteristic value are generated, the difference between the state characteristic values of adjacent nodes, time interval deviation and the second-order difference of process characteristic value generate stage transition signature, based on state characteristic value, stage transition signature, batch fingerprint and time sequence characteristic value generate rhythm anchor point vector;Dynamic Merkle tree is constructed and layered chain anchor point is extracted;Chain storage and verification;Output composite score and determine the credibility level.The scheme realizes the three-layer binding of node authenticity, stage continuity and order rhythm uniqueness, and enhances the progress non-portable proof capability.
