Embodiment Construction
[0066] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.
[0067] first embodiment.
[0068] Such as Figure 1 to Figure 5 As shown, an article anti-counterfeiting and traceability method realized by using blockchain and its smart contract, the specific steps of the method at the production end 100 include:
[0069] Step S101: Deploy the smart contract, obtain the hash value returned by the blockchain 302: call the blockchain interface, publish a transaction 301 for deploying the smart contract to the blockchain, and obtain the hash value corresponding to the transaction 1 returned by the blockchain Hash value one 302;
[0070] Among them, for blockchain technology, the smart contract can be considered as a program running on the blockchain, so before deploying the smart contract, it is necessary to write the source program of the smart contract and c...
