The application discloses a
blockchain-based agricultural food
source tracing method and
system, and relates to the technical field of supply chain credible management, comprising the following steps: collecting original batch numbers, splitting records, packaging numbers and
handover times in the agricultural food
source tracing link, uniformly storing the collected data into a distributed storage
system, and generating batch tracing indexes. The application realizes continuous tracking of the identity of agricultural food from production to sales through the establishment of batch tracing indexes and batch inheritance lists. Through a double-index structure and reverse supplement and forward freezing mechanisms, the data on the chain is ensured to remain consistent in dynamic changes, batch breaks and information
confusion are avoided, and full-life-cycle tracing management with traceable sources, reliable records and stable systems is realized.
