Embodiment 1

[0032] figure 1 A system block diagram of an embodiment of the blockchain-based tax refund system provided by the present invention. Such as figure 1 As shown, the blockchain-based tax refund system provided by the embodiment of the present invention includes: a plurality of fulfillment nodes 11 and at least one review node 12 .

[0033] Among them, the fulfillment node 11 corresponds to the performer of the transaction, and is used to store the fulfillment information for the transaction; the review node 12 corresponds to the reviewer of the tax refund application, and is used to obtain information from the corresponding fulfillment node 11 according to the transaction identifier input by the user. Obtain the performance information of the transaction uniquely identified by the transaction identifier, verify the performance information according to the preset strategy, and trigger the tax refund operation for the transaction when the verification is passed.

[0034] In the ...

Embodiment 2

[0038] Such as figure 1 shown in the above figure 1 On the basis of the illustrated embodiment, in the blockchain-based tax refund system provided by the embodiment of the present invention, the performance node 11 can also be used to store the performance data for the transaction, and the audit node 12 can also be used to In the case of , obtain the performance data for the transaction from the performance node 11, and trigger the tax refund review operation for the performance data.

[0039]In the embodiment of the present invention, when the audit node 12 runs the smart contract to verify the acquired performance information for the transaction (including but not limited to: order information, logistics information, foreign exchange payment information and customs declaration information of the transaction), If the verification fails, it means that there is a problem in the obtained performance information, which does not meet the tax refund conditions. For the suspicious ...

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.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a block chain-based tax rebate method and system and electronic equipment. Background technique [0002] In the existing export tax rebate link, the applicant (for example, export factory, trading company, etc.) needs to submit various materials by itself, and prepare various evidence documents for verification by the tax authority.
