| description | The invention discloses a two-dimensional code anti-counterfeiting traceability realization method based on a block chain. The method employs a two-dimensional code publisher, an authentication service center, a block chain platform and a user, wherein the authentication service center carries out the identity authentication on the two-dimensional code publisher through employing a signature technology, the two-dimensional code publisher deploys the anti-counterfeiting two-dimensional code system on the block chain through the smart contract, and the user scans the two-dimensional code to callthe smart contract to inquire the commodity information to the block chain platform; the release and query actions of the commodity two-dimensional code are recorded on the block chain platform, andthe block chain platform counts the query frequency of the commodity two-dimensional code and the queried account and feeds back the query frequency and the queried account to the user. On the block chain, the identity authent |
