The anti-counterfeiting traceability system based on blockchain technology can ensure the accuracy and consistency of the data stored by each participating node, protect the legitimacy of the data, ensure the product quality, improve the credibility of enterprises, and enhance consumers’ confidence in products. However, due to the low system throughput, high energy consumption and poor data availability, the combination of blockchain and traditional anti-counterfeiting traceability mode has many challenges, such as low efficiency. This paper aims to find an improved consensus mechanism based on contribution proof to improve the mining efficiency of honest miners. And plan to introduce a credit system, give priority to the high credit value of the mining block to package, improve the overall packaging efficiency of the system, to solve the problem of low feedback efficiency of the blockchain anti-counterfeiting system.
