The value-added tax electronic invoice is a product of era information, is used by merchants in a form of uniform distribution of a tax bureau like a common invoice, adopts national uniform coding of invoice numbers, adopts a uniform anti-counterfeiting technology, is distributed to the merchants, and is paid with a signature mechanism of the electronic tax bureau.
The inventor finds that the conventional bank invoice management system has the risks that the collection transaction time is delayed, a client cannot obtain an invoice immediately, a centralized database is internally tampered, and a false invoice is issued by joint action.
The block chain technology is a distributed transaction verification and data sharing technology, so that a value-added tax electronic invoice system can be constructed by using the block chain technology, a database which is composed of multiple nodes and can not be tampered is realized by using the block chain technology, each upstream system related to an invoice is used as an accounting node, in addition, an invoice uploading server is required to be built and used as an endorsement node, all transaction and invoice information is recorded and is butted with a national electronic ledger base, and invoice uploading is realized. It has the following characteristics:
①, it is not necessary to collect all business transactions to the invoice management system, at the first time when each business system generates transaction action, the related data information of the transaction is recorded on the block chain, and at the same time, according to the tax information set by the client in advance, the system automatically issues value-added tax electronic invoice, and puts the value-added tax electronic invoice and the transaction information into the same block and records on the chain.
②, it is difficult to forge data recorded by the blockchain technique unless the forger can control 51% of the system nodes throughout the network.
③ non-repudiation since each transaction record process leaves a record for any one node, the transaction is not repudiated by both parties once it occurs.
Therefore, the embodiment of the invention constructs a private chain platform for invoice information management by using a decentralized management mode of a block chain, a bookkeeping server is arranged at each upstream system related to the invoice, each business system generates the first time of transaction behavior, the bookkeeping server records related transaction information and invoicing information and broadcasts and issues the related transaction information and invoicing information to all other bookkeeping servers, a centralized invoice management system does not need to be established for transaction collection and invoicing, and the private chain has good privacy and the decentralized point of the block chain, so that the hysteresis of transaction collection is avoided, the real-time invoicing is realized, the invoicing efficiency is improved, the case of internal personnel can be prevented, and the risk of virtual invoicing is avoided.
