Block chain computing method, system and equipment based on trusted execution environment and medium

The invention provides a block chain calculation method, system and device based on a trusted execution environment and a medium, and the method comprises the steps: obtaining a calculation request, carrying out the authority verification of the calculation request, and determining the data needed by calculation according to the calculation request when the authority verification is passed; performing data retrieval according to the data required by calculation to obtain sample data; performing data encryption on the calculation request and the sample data through an asymmetric encryption algorithm to obtain to-be-calculated encrypted data, and transmitting the to-be-calculated encrypted data to an intelligent calculation module; and the intelligent calculation module decrypts the encrypted data by using a private key to obtain decrypted data, executes intelligent calculation under the chain of the block chain based on the decrypted data, and sends an intelligent calculation result to the block chain for veri
