The application discloses a
blockchain intelligent supervision
system and method based on on-chain and off-chain data fusion, relates to the technical field of blockchains, and constructs an index
linked list of cross-chain events; generates a unified cross-node
time sequence data sequence, and matches the index
linked list of cross-chain events to generate a structured event vector; based on cross-node
log data and an event behavior
feature vector, a supply
chain link deviation and an abnormal index are calculated, key links such as transportation timeliness, inventory fluctuation and quality parameters are subjected to abnormal
feature extraction and quantitative description; a behavior deviation feature sequence is formed through threshold value judgment and
statistical analysis; based on the behavior deviation feature sequence, the confidence of a behavior feature is calculated, and combined with cross-chain correlation indexes, abnormal
event tracing is realized, the supply chain full-link
traceability, data credibility and intelligent abnormal identification are realized, and the safety is significantly improved.
