1. A data processing method, applied to a first trusted computing node, and comprising:
obtaining data to be verified from a target trusted computing node, the data to be verified being data stored by a target terminal device corresponding to the target trusted computing node in the target trusted computing node;
obtaining first ledger data corresponding to the data to be verified from an accessed blockchain network, the first ledger data being obtained by signing a first message digest by using a private key of the target trusted computing node and being stored in the blockchain network by the target trusted computing node, and the first message digest being obtained by performing message digest calculation on raw data corresponding to the data to be verified;
decrypting the first ledger data by using a public key of the target trusted computing node to obtain the first message digest;
performing message digest calculation on the data to be verified to obtain a second message digest;
determining a verification result of the data to be verified according to the first message digest and the second message digest; and
in response to that the verification result indicates that the data to be verified is authentic, processing the data to be verified and first data stored by a first terminal device in the first trusted computing node to obtain a first result, and sending the first result to the first terminal device associated with the first trusted computing node, wherein the processing the data to be verified and the first data comprises intersection set calculation processing or conversion rate calculation processing.
