Abstract

A blockchain transaction record that is selected from a blockchain account book associated with a blockchain and satisfies a specified condition is obtained by a blockchain member. The blockchain transaction record is compared with an off-chain transaction record maintained by the blockchain member to obtain a comparison value indicating whether the off-chain transaction record is consistent with the blockchain transaction record. If the comparison value indicates that the off-chain transaction record is inconsistent with the blockchain transaction record, the off-chain transaction record is modified based on the blockchain transaction record to make the off-chain transaction record consistent with the blockchain transaction record.
