Non-homogeneous token image query method and system based on block chain

The invention provides a block chain-based non-homogeneous token image query method and system, which can be applied to the technical field of block chains, and the method comprises the following steps: receiving an image query request sent by a client of a target user; obtaining a right and interest relation table corresponding to the image query request from a block chain; querying from an interstellar file system to obtain a target image file corresponding to the right and interest relation table; the target image file comprises a combined image file obtained by combining non-homogeneous token image files in a plurality of storage nodes of the interstellar file system, and the combined image file is stored in a uniquely corresponding main storage node and standby storage node; the main storage node and the standby storage node are storage nodes in the interstellar file system. According to the method and the device, combination and centralized storage of the plurality of non-homogenized token images can be
