The invention provides an agricultural
product traceability system based on a block chain. The
system comprises an agricultural product
big data platform, an agricultural
product traceability query platform, and a 5
G network; the agricultural product
big data platform comprises an agricultural product growth information module, a storage information module, a
processing information module and a sales information module; the agricultural
product traceability query platform comprises a
data restoration module, an anti-counterfeiting query module and a
traceability information query module; and each module carries out data uploading and
traceability query through a 5
G network. According to the invention, further optimization is carried out on the basis of a
traceability system based on a block chain; an agricultural product tracing system combining the advantages of a private chain and a public chain is designed. On the basis of preventing the agricultural product information from being attacked and tampered, the certified
product label is further prevented from being stolen and copied, the data
storage efficiency is improved, the calculation expenditure is reduced, and consumers or supervision departments can quickly position production links and responsible persons of problematic agricultural products.
