13. The system of claim 10, wherein the factory tracing information further comprises geographical location information of a commodity production node or production geographical location information of the target commodity.
14. The system as claimed in claim 10, wherein the circulation tracing information further includes circulation information when the commodity circulation node circulates the target commodity.
15. The system of claim 10, further comprising:
and the commodity consumption node acquires the traceability information stored in the storage medium of the target commodity and the anti-counterfeiting check information of the target commodity stored in the traceability block chain so as to perform anti-counterfeiting check on the target commodity.
16. The system of claim 15, further comprising:
after the commodity consumption node passes the anti-counterfeiting check on the target commodity and purchases the target commodity, the purchase information of the target commodity is written into a storage medium of the target commodity, and the transaction of the anti-counterfeiting check information carrying the purchase information of the target commodity is submitted into the tracing area block chain.
17. The system as claimed in any one of claims 10 to 16, wherein the storage medium provided in the target product comprises an NFC chip embedded in the target product.
18. The system of any one of claims 10 to 16,
and the commodity circulation node acquires a public key stored in the traceability block chain, and verifies the anti-counterfeiting check information of the target commodity stored in the traceability block chain through the public key so as to perform anti-counterfeiting check on the target commodity.
