Abstract: The present disclosure relates to a smart contract-based data transfer method, comprising the steps of: a data source encrypting data to be transferred based on a first mechanism to form encrypted data, and sending the encrypted data to a smart contract terminal; the smart contract terminal decrypting the encrypted data based on a second mechanism corresponding to the first mechanism to form the decrypted data, and processing the decrypted data by using at least one logic unit to form the resulting data; and the smart contract terminal sending the resulting data to a data-related party; wherein the at least one logic unit executes an instruction set to implement a contract logic, and the instruction set is stored in a blockchain.
