Abstract

The invention discloses a finance and tax block chain multi-chain invoice management system and method, relates to the technical field of block chains, is used for ensuring authenticity and rationality of invoice issuing and avoiding false invoice issuing and tax evasion; and the finance and tax block chain multi-chain invoice management system comprises a commodity circulation chain, a tax invoice chain, a fund settlement chain, and at least one node that is located on the commodity circulation chain, the tax invoice chain and the fund settlement chain and comprises a buyer node and a seller node; the commodity circulation chain is used for recording circulation information of commodities involved in commodity transaction; the tax invoice chain is used for generating invoice information corresponding to the commodity transaction when it is determined that a difference value between a first fund corresponding to the commodity transaction and a second fund corresponding to the number of commodities determined according to the circulation information is smaller than a first threshold value; and the fund settlement chain is used for drawing the amount corresponding to the first fund from the account of the buyer node of the commodity transaction to the account of the seller node of the commodity transaction.

Description

technical field [0001] This application relates to the technical field of blockchain, in particular to a financial and taxation blockchain multi-chain invoice management system and method. Background technique [0002] At present, when using the blockchain to issue invoices, usually the transaction amount, commodity data, commodity type, tax ID and other invoice information related to invoice issuance are packaged into a block by both parties to the transaction, and the block is linked to the block. In the block chain, the invoice information is uploaded to the chain. When an invoice needs to be issued for a transaction, the invoice information on the block chain of the billing node issues an invoice. If both parties to the transaction use false invoice information and upload the false invoice information to the chain, then false invoices can still be issued based on the false invoice information, and both parties to the transaction can use false invoices to evade taxes. ...
