Trusted computing unloading method and system based on extensible block chain

The invention belongs to the technical field of block chains, and provides a trusted computing unloading method and system based on an extensible block chain, and the method comprises the following steps: uploading computing task information needing to be unloaded; transmitting the request information to a block chain system; verifying the request information, and calculating and obtaining an unloading decision according to the calculation task information; outputting an unloading scheme, packaging the legal request and the unloading scheme into a block, and recording the block as a current block; consensus is carried out on the current block, and other nodes verify the request information and the unloading scheme to determine whether to receive the current block; and after the current block is determined to be accepted, the current block is linked to the block chain, and the task is transmitted to the corresponding node according to the unloading scheme. According to the calculation unloading method provided
