The invention relates to the technical field of agricultural product supply chain management, in particular to an agricultural product supply chain information tracing method and
system, and the method comprises the steps: constructing an alliance block chain architecture, employing an alliance block chain mode to absorb agricultural product supply chain participants as alliance nodes, and designing a multi-level block
chain structure; the method comprises the following steps: deploying
Internet of Things equipment in an agricultural product planting and breeding link and a
processing link to carry out
data acquisition, endowing the acquired data with a
unique object identifier, and carrying out identification and recording by utilizing equipment with a two-dimensional code or an RFID (
Radio Frequency Identification) tag; after identification and recording are completed,
encryption processing is carried out on all data, and
consensus mechanism optimization is carried out; an agricultural product supply chain information
traceability query
system is constructed, and consumers and supervision departments perform
traceability query in all directions. The block chain and
the Internet of Things are combined with the
object identifier technology, so that the query efficiency of the agricultural product supply chain information is improved, and the agricultural product
quality safety guarantee level is improved.
