Design and Implementation of Blockchain-based Commodity Anti-counterfeit Traceability System

With the booming development of big data technology, people pay more and more attention to the importance of data, and various big data analysis technologies have emerged; blockchain is widely used in anti-counterfeit traceability of commodities with its unique advantages, such as decentralization and non-tamper ability. Due to the popularity of anti-counterfeit traceability systems, more and more commodities support the function of checking authenticity; however, most of the current commodity checking systems do not make use of the data of historical checking, thus leading to unsatisfactory anti-counterfeit effects. In this paper, big data and blockchain technology are applied to the anti-counterfeiting and traceability system to give a unique code to each commodity and generate a corresponding QR code; when consumers scan the code to check, the system uses big data technology to calculate all the historical check records of the commodity and derive the reliability of this check. By setting the reliability threshold, we can achieve the purpose of anti-counterfeiting of commodities.
