Research on the Deployment Strategy of Blockchain Nodes in the Agricultural Product Blockchain Traceability System

The agricultural product traceability system based on blockchain can monitor the entire growth cycle of agricultural products, trace it at any time, and cannot tamper with information without authorization. However, the energy consumption of the entire system is relatively high due to the introduction of blockchain technology. In order to alleviate the problem of high overall energy consumption, we are trying to reduce the communication power consumption between terminal sensors and the full nodes of the blockchain. We use the K-means algorithm, the DBSCAN algorithm and the improved DK fusion algorithm we proposed to deploy blockchain full nodes to the agricultural products sensors that have been determined to reduce the communication power consumption of the sensor terminals and improve the coverage of the full nodes to the terminal sensors.
