File storage method and device, file query method and device, electronic equipment and storage medium

The invention provides a file storage method and device, a file query method and device, electronic equipment and a storage medium. Relates to the technical field of computers. The method comprises the following steps: after a server acquires a to-be-stored first data file sent by terminal equipment, storing the first data file through a distributed system, and receiving a first file identifier returned by the distributed system for the first data file, and the first file identifier and the hash code of the first data file are stored through the block chain network, and a storage success message containing the first file identifier is returned to the terminal equipment. Therefore, the to-be-stored data file is stored through the distributed system, and the related information of the data file is stored through the block chain network, so that the pressure of the server for storing the data file and the corresponding related information can be reduced while the storage security and reliability of the data file
