Abstract: A first apparatus sends a first random number to a second apparatus, where a vehicle carries the first apparatus and a first set. The second apparatus belongs to the first set. The first set further includes a third apparatus. The first apparatus communicates with the third apparatus using the second apparatus. The first apparatus receives a first message from the second apparatus. The first message includes first verification information to perform identity verification on the second apparatus. The first verification information is based on identity information of the second apparatus and the first random number. The first apparatus determines, based on the first verification information and the first random number, that the identity verification on the second apparatus has succeeded.

Abstract: Embodiments of this application provide a blockchain-based data processing method, a device, and a medium. The method includes: sending a first channel closing message on a chain-off channel; receiving a second signature in a second state and a second channel closing message that are sent on the off-chain channel, where the second signature is obtained by signing the second channel closing message; and signing a third channel closing message to obtain a first signature in the second state, and sending the first signature. This application can ensure transaction security and improve a transaction processing capability.

Abstract: This application provides a data processing method and a computing platform. The method includes: The computing platform obtains data and a computing task description, where the computing task description includes computing that needs to be performed on the data; the computing platform selects a first operator set based on the computing task description, where the first operator set includes a plurality of basic operators; and the computing platform executes, based on a dependency relationship between the basic operators in the first operator set, the first operator set to compute the data, to obtain a computation result of the data, where a placeholder of an input operand of one of two basic operators that have the dependency relationship intersects with a placeholder of an output operand of another basic operator.
