Abstract
A data processing method may include: determining, by a transaction initiation node in a blockchain, transaction data of a transaction and information to be hidden in the transaction data; obtaining, by using the transaction data as an input of a predetermined one-way function, a transaction root of the transaction, and constructing, based on the transaction root, proof data corresponding to the information to be hidden; and, after signing the transaction root, initiating a transaction request to write the transaction root and the proof data on the blockchain, for a node in the blockchain to perform consensus verification on the transaction root and the proof data, and approve or reject the transaction request based on a verification result.
