A blockchain-based method for anti-counterfeiting verification on a target product, wherein the target product is attached with an anti-counterfeiting label, a blockchain stores anti-counterfeiting information corresponding to the target product, and the anti-counterfeiting information comprises an anti-counterfeiting identification code generated by an anti-counterfeiting authority for the target product, and a plurality of types of anti-counterfeiting identification information that are generated by other anti-counterfeiting participants and stored in association with the anti-counterfeiting identification code, wherein the anti-counterfeiting identification code and the anti-counterfeiting identification information are stored in the blockchain by the anti-counterfeiting authority and the other anti-counterfeiting participants, the anti-counterfeiting label attached with the target product is generated based on the anti-counterfeiting identification code, and the method comprises: obtaining an anti-counterfeiting verification request submitted by a user for the target product, wherein the anti-counterfeiting verification request comprises the anti-counterfeiting identification code obtained by scanning the anti-counterfeiting label; initiating an anti-counterfeiting verification on the target product in response to the anti-counterfeiting verification request, wherein the anti-counterfeiting verification comprises at least an integrity verification on the anti-counterfeiting information, wherein initiating the anti-counterfeiting verification on the target product in response to the anti-counterfeiting verification request comprises: initiating a query in the blockchain based on the anti-counterfeiting identification code in the anti-counterfeiting verification request in response to the anti-counterfeiting verification request, to detect the plurality of types of anti-counterfeiting identification information that are generated by the other anti-counterfeiting participants and stored in association with the anti-counterfeiting identification code; and determining that the target product passes the anti-counterfeiting verification, comprising at least determining that the target product passes the integrity verification on the anti-counterfeiting information, wherein the target product passes the integrity verification on the anti-counterfeiting information if the plurality of types of anti-counterfeiting identification information that are generated by the other anti-counterfeiting participants and stored in association with the anti-counterfeiting identification code are detected; and returning an anti-counterfeiting verification result for the target product to the user. obtaining an anti-counterfeiting verification request submitted by a user for the target product, wherein the anti-counterfeiting verification request comprises the anti-counterfeiting identification code obtained by scanning the anti-counterfeiting label; initiating an anti-counterfeiting verification on the target product in response to the anti-counterfeiting verification request, wherein the anti-counterfeiting verification comprises at least an integrity verification on the anti-counterfeiting information, wherein initiating the anti-counterfeiting verification on the target product in response to the anti-counterfeiting verification request comprises: initiating a query in the blockchain based on the anti-counterfeiting identification code in the anti-counterfeiting verification request in response to the anti-counterfeiting verification request, to detect the plurality of types of anti-counterfeiting identification information that are generated by the other anti-counterfeiting participants and stored in association with the anti-counterfeiting identification code; and determining that the target product passes the anti-counterfeiting verification, comprising at least determining that the target product passes the integrity verification on the anti-counterfeiting information, wherein the target product passes the integrity verification on the anti-counterfeiting information if the plurality of types of anti-counterfeiting identification information that are generated by the other anti-counterfeiting participants and stored in association with the anti-counterfeiting identification code are detected; and initiating a query in the blockchain based on the anti-counterfeiting identification code in the anti-counterfeiting verification request in response to the anti-counterfeiting verification request, to detect the plurality of types of anti-counterfeiting identification information that are generated by the other anti-counterfeiting participants and stored in association with the anti-counterfeiting identification code; and determining that the target product passes the anti-counterfeiting verification, comprising at least determining that the target product passes the integrity verification on the anti-counterfeiting information, wherein the target product passes the integrity verification on the anti-counterfeiting information if the plurality of types of anti-counterfeiting identification information that are generated by the other anti-counterfeiting participants and stored in association with the anti-counterfeiting identification code are detected; and returning an anti-counterfeiting verification result for the target product to the user.
