Abstract
Examples in this application disclose data verification methods, media, and systems. One example method includes receiving, from a blockchain network by a trusted execution environment (TEE) in a blockchain node, a trigger instruction based on a timed starting logic identifying a starting time to execute a smart contract, where the timed starting logic is comprised in a chain code which comprises information of a blockchain account and is executable by the blockchain node to determine the information of the blockchain account, retrieving first encrypted data from a first institution, decrypting the first encrypted data, receiving a data sharing request comprising a user identity corresponding to user basic data from a second institution, retrieving the user basic data based on the user identity, performing verification processing of the user basic data based on the trigger instruction to obtain a verification result, and sending the verification result to the second institution.
