Abstract

A blockchain audit system includes: an audit control interface, receiving a transaction data which is written into a transaction database; an audit blockchain connected to the audit control interface, to record multiple audit-confirmed transaction records. The audit control interface generates a transaction record according to the received transaction data and adds the transaction record to a database transaction record summary table; if the transaction record is in a database transaction record missing list, the transaction record in the database transaction record missing list is removed, otherwise, if the transaction record is in a blockchain transaction record summary table, the transaction record is added to an audit-confirmed transaction record list, and a transaction block number of the transaction record is written back to the corresponding transaction data in the transaction database.

Claims12

Dependent claims

A blockchain audit system, including:

an audit control interface, which receives multiple transaction data written into a transaction database, and receives multiple transaction data uploaded to a transaction blockchain;
wherein the audit control interface compares two of the received multiple transaction data written into the transaction database and the received multiple transaction data uploaded to the transaction blockchain, and matched transaction data between the two are recorded by the audit control interface as audit-confirmed transaction records;
an audit blockchain, connected to the audit control interface;
when the audit control interface receives a transaction block number of a newly added transaction block from the transaction blockchain, the audit control interface creates a new audit block in the audit blockchain to record the audit-confirmed transaction records;
wherein the transaction blockchain and the audit blockchain respectively comprise a plurality of nodes each of which is a physical computer device with networking capabilities and with a corresponding storage device.
