Application of Blockchain and RFID in Anti-counterfeiting Traceability of Liquor

Abstract

In view of the current situation of counterfeit liquor in the liquor industry, this paper develops a liquor anti-counterfeiting traceability system based on Ethereum and RFID in combination with blockchain and Internet of Things technologies. The system uses RFID readers to automatically upload information in the liquor supply chain, and stores the hash value of the information in the blockchain to ensure that the information cannot be tampered and traceable. The smart contract can open different query permissions according to different users. Through this system, the trust of the community in the enterprise can be improved, and at the same time, it is conducive to promoting the modernization process and healthy development of the liquor industry.
