Abstract

The embodiment of the invention provides a tax refund method and system based on a block chain and electronic equipment. The method comprises the following steps of acquiring performance information of a transaction uniquely identified by a transaction identifier from a corresponding performance node according to the transaction identifier of the transaction, verifying the performance informationaccording to a preset strategy, and when the verification is passed, triggering a tax refund operation for the transaction. According to the embodiment of the invention, the performance information inthe whole trade performance process is uploaded to the performance node of the block chain, the system processes a tax refund application. Only the corresponding transaction identifier needs to be obtained, auditing is convenient, the transaction performance information can be obtained from the corresponding performance node through the auditing node according to the transaction identifier, according to the method and the device, the information verification is carried out, and the tax refund operation is triggered according to the verification result, so that the human input and the time input in the tax refund link can be reduced, the human cost is reduced, the tax refund period is shortened, and the tax refund auditing accuracy is improved by utilizing the tamper resistance of the datain the block chain.
