Block chain data management method and device, electronic equipment and storage medium

The invention provides a block chain data management method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining the personal information of a user, collecting the data of each node based on the information, and carrying out the classification of the data through a neural network model. And dividing the data into first data and second data according to a classification result, and storing the first data and the second data to the corresponding first equipment and the second equipment. Dynamically adjusting the storage position of the first data or the second data according to the access frequency of the user for accessing the stored first data or the second data, specifically, if the access frequency is lower than a preset value, storing the first data or the second data to the first equipment; and if the access frequency is higher than or equal to the preset value, storing the access frequency to the second equipment. Through intelligent data classification, st
