Audit application solution based on blockchain smart contract

The invention discloses an audit application solution based on a blockchain smart contract, and belongs to the field of blockchain technology application. The solution is mainly characterized in thatthe solution is mainly as follows: an audited intelligent contract is operated on a block chain supporting data uplink; the auditor submits auditing evidences to the block chain through the intelligent contract, wherein the auditing evidences are marked as to-be-confirmed auditing evidences, the auditing expert group audits the auditing evidences and feeds back agreement or anti-agreement, and after more than half of members of the auditing expert group agrees or anti-agrees, the intelligent contract automatically changes the states of the auditing evidences into formal or invalid states and stores the auditing evidences in the blockchain.
