Real-time information sharing model of product supply chain based on Internet of Things

In order to overcome the problems of poor information security and low sharing efficiency existing in the traditional product supply chain information real-time sharing model, this paper proposes a new product supply chain information real-time sharing model based on Internet of Things technology. Set the information double chain storage mode, calculate the data writing speed of the Internet of Things, determine the optimal block size of the product supply chain through the difficulty control algorithm, and optimise the anti tampering ability of the model to the information when there are attacks in the supply chain. Using the supply chain technology to establish the underlying peer-to-peer network, the dual chain storage of regional product information data sharing, building product information real-time sharing model. Experimental results show that compared with the traditional model, this model has higher security and sharing efficiency, and the sharing efficiency is always above 90%.
