Embodiment

[0049] This embodiment takes the anti-counterfeiting traceability of stamps as an example to describe the system and method of the present invention.

[0050] An anti-counterfeiting traceability system for bill supply chain based on blockchain NFT, including two-dimensional code anti-counterfeiting label, stamp information on-chain module, publicly certified blockchain platform, blockchain ETL gateway, stamp circulation information acquisition module, traceability query module, mobile intelligent read-write terminal and NFT transfer module.

[0051] The stamp invisible two-dimensional code anti-counterfeiting label: the two-dimensional code generation and reading and writing system generates a two-dimensional code label, and the two-dimensional code anti-counterfeiting label is a hidden code and is printed on the same side as the stamp pattern. In order to further ensure security, the QR code information of the bill is hashed and sent to the blockchain platform, and the basic ...

Abstract

The invention relates to an anti-counterfeiting traceability system and method for a bill supply chain based on blockchain NFT, and belongs to the technical field of blockchain applications. In this method, in the online and offline business chain, by setting up a blockchain oracle, real-time monitoring of the real assets of offline chain bills is performed; the NFT contract is safely generated and transferred through the online chain and offline chain parallel business chain system to realize Information synchronization of online and offline bill supply chains; the invisible anti-counterfeiting QR code anti-counterfeiting labels printed on bills are deployed on the blockchain through smart contracts; The platform calls the smart contract to query the basic information and circulation information of the bill. The invention realizes the transparency, decentralization and traceability of the bill supply chain, maintains high fidelity and timeliness, and is beneficial to improve the security of bill transactions.

Description

technical field [0001] The invention relates to an anti-counterfeiting traceability system and method for a bill supply chain based on blockchain NFT (Non-Fungible Tokens), belonging to the technical field of blockchain applications. Background technique [0002] As a kind of bill vouchers issued by relevant state departments, stamps and tickets have both cultural attributes and commodity attributes. Due to the scarcity of a single category, the commemoration of special events, and the exquisite printing, this kind of bill collection market has become a long-term and stable trading market, and its cultural value, especially its market value, has attracted a large number of collectors. It has created a booming online and offline market. For example, the issuance of stamps is currently mainly in the form of physical stamp issuance, with online and offline reservations and retail as the main sales methods. In the secondary stamp trading market, it is generally private communi...
