Embodiments of the present disclosure provide methods and apparatuses for blockchain-based multi-party computation, a device and a medium, relate to blockchain technology in the field of computer technology. An embodiment of the method can include: encrypting business data, to obtain a ciphertext of the business data; hashing the ciphertext of the business data, to obtain a hash result of the business data; sending the hash result of the business data to a blockchain node, so that the blockchain node writes the hash result of the business data into a blockchain; and sending the ciphertext of the business data to a target trusted computing module in a target server, for instructing the target trusted computing module to perform multi-party computation based on the ciphertext of the business data and the hash result of the business data in the blockchain.

Method, apparatus for blockchain-based multi-party computation, device and medium

A system may include a computer-readable storage medium configured to store a first set of instructions for determining one or more candidate driver terminals to accept a service request; and a processor in communication with the computer-readable storage medium, wherein when executing the first set of instructions, the processor is directed to: establish a communication with a passenger terminal; obtain a service request including a position of the passenger terminal from the passenger terminal: determine a wireless fidelity (WiFi) station based on the position of the passenger terminal; determine one or more driver terminals that access the WiFi station; determine an access instance of each of the one or more driver terminals; and determine one or more candidate driver terminals among the one or more driver terminals based on the one or more access instances of the one or more driver terminals.
