In particular, a blockchain may be understood as a decentralized distributed ledger database.
Prediction machine: the mechanism by which information outside the blockchain is written inside the blockchain is generally called an oracle mechanism (oracle mechanism). Specifically, the prediction machine has the function of writing external information into the block chain to complete data intercommunication between the block chain and the real world. The method allows the determined intelligent contract to react to the uncertain external world, is the only way for the intelligent contract to perform data interaction with the outside, and is also an interface for the block chain to perform data interaction with the real world.
As mentioned above, in the prior art, when performing the consumption reimbursement, reimbursement staff need to pay consumption funds in advance, then submit corresponding certification information corresponding to the consumption funds, such as tickets, invoices, shopping tickets, and the like, to corresponding auditors, and then perform corresponding reimbursement after the auditors complete the audit, so as to complete reimbursement, and the whole reimbursement process is complicated, thereby resulting in low reimbursement efficiency.
In view of this, the present invention provides a reimbursement method based on a block chain, by which consumption data generated by reimbursement personnel and fund settlement data corresponding to the consumption data can be acquired through nodes in the block chain, so that a server corresponding to the nodes can complete reimbursement for consumption according to the acquired data, and reimbursement efficiency is greatly improved.
After the design idea of the embodiment of the present invention is introduced, some simple descriptions are provided below for application scenarios to which the technical solution of the embodiment of the present invention can be applied, and it should be noted that the application scenarios described below are only used for illustrating the embodiment of the present invention and are not limited. In the specific implementation process, the technical scheme provided by the embodiment of the invention can be flexibly applied according to actual needs.
The technical scheme provided by the embodiment of the invention can be applied to various reimbursement scenes such as enterprise employee reimbursement, campus student reimbursement and teacher reimbursement, and the embodiment of the invention is not limited.
In the embodiment of the present invention, a fiscal and taxation block chain system corresponding to the corresponding scene may be established, and specifically, the fiscal and taxation block chain system may include an article circulation chain for recording article circulation transactions, a fund settlement chain for recording fund settlement transactions, and a tax invoice chain for recording tax payment transactions and reimbursements. In order to facilitate understanding of the technical solutions provided in the embodiments of the present invention, the reimbursement of the enterprise staff is taken as an example in the following.
In a specific implementation process, during activities such as business trips, the enterprise staff may perform various consumption-related data such as commodity purchasing, travel expenses, meetings, training and the like related to the business of the company with the cooperation party related to the business of the company, for example, data of commodity purchasing quantity, data of travel time and place such as taxies, airplanes, subways, high-speed rails, trains and the like. And then the server corresponding to the partner can upload the consumption data generated by the commodity transaction to the commodity circulation data chain, so that any node on the commodity circulation chain can acquire the data. Specifically, the commodity circulation chain may include a plurality of nodes, that is, a plurality of partners may upload data through different nodes.
In a specific implementation process, after the enterprise employee performs an article transaction with the partner in an event of business trip or the like, corresponding fund consumption data is correspondingly generated, for example, a consumption amount of commodity purchase, a consumption amount of a ticket, a consumption amount of accommodation, and the like, and then a server corresponding to the partner may upload the consumption fund data to a fund settlement chain, so that a node in the fund settlement chain may acquire the consumption fund data. Specifically, the fund settlement chain may include a plurality of nodes, that is, a plurality of partners may upload data through different nodes.
In the embodiment of the invention, the goods circulation predicting machine node in the tax invoice chain can acquire the consumption data in the goods circulation chain, and the fund settlement predicting machine node can acquire the fund settlement data determined by the consumption data of the goods, so that the acquired information can be reimbursed, and the reimbursement process can be further completed. It should be noted that any node in the tax invoice chain that satisfies the prolog mechanism may be referred to as a prolog mechanism node, and in order to facilitate understanding, in the embodiment of the present invention, a node that satisfies the prolog mechanism and acquires consumption data is referred to as an article circulation prolog mechanism node, a node that satisfies the prolog mechanism and acquires fund settlement data is referred to as a fund settlement prolog mechanism node, and a node corresponding to a server that specifically processes a transaction is referred to as a corresponding functional node, such as a reimbursement node, an audit node, a transaction node, and the like.
In a specific implementation process, the nodes in the block chain can be connected with each other through the internet to realize mutual communication. Optionally, the internet described above uses standard communication techniques and/or protocols. The internet is typically the internet, but can be any Network including, but not limited to, a Local Area Network (LAN), a Metropolitan Area Network (MAN), a Wide Area Network (WAN), any combination of mobile, wireline or wireless networks, private or virtual private networks. In some embodiments, data exchanged over a network is represented using techniques and/or formats including Hypertext Mark-up Language (HTML), Extensible Markup Language (XML), and the like. All or some of the links may also be encrypted using conventional encryption techniques such as Secure Socket Layer (SSL), Transport Layer Security (TLS), Virtual Private Network (VPN), Internet Protocol Security (IPsec). In other embodiments, custom and/or dedicated data communication techniques may also be used in place of, or in addition to, the data communication techniques described above.
To further illustrate the technical solutions provided by the embodiments of the present invention, the following detailed description is made with reference to the accompanying drawings and the specific embodiments. Although embodiments of the present invention provide method steps as shown in the following embodiments or figures, more or fewer steps may be included in the method based on conventional or non-inventive efforts. In steps where no necessary causal relationship exists logically, the order of execution of the steps is not limited to that provided by embodiments of the present invention. The method can be executed in sequence or in parallel according to the method shown in the embodiment or the figure when the method is executed in an actual processing procedure or a device.
Referring to fig. 1, a schematic flow chart of a block chain-based reimbursement method according to an embodiment of the present invention is shown, where the method can be applied to the aforementioned fiscal/tax block chain multi-chain system, and a flow of the method is described below.
Step 101: the tax invoice chain acquires the consumption data of the goods consumed by the sales personnel in the goods circulation chain through the goods circulation prediction machine node.
Step 102: and the tax invoice chain acquires fund settlement data determined by the consumption data of the goods in the fund settlement chain through the fund settlement prompter node.
In the embodiment of the invention, the office system inside the enterprise decides to generate the transaction expense permission, namely confirms the transaction authorization authority and the sponsor, and records the transaction expense permission on the public fund settlement account outside the enterprise. When the operator and the partner complete the transaction, the transaction payment permit can be consumed, namely the fund settlement is carried out on the public fund settlement account outside the enterprise directly through the transaction payment permit, so that the actual fund settlement can be completed without paying the consumption fund by the operator.
In the embodiment of the invention, the reimbursement personnel with reimbursement authority transact with the partner to generate consumption data, for example, the reimbursement personnel with reimbursement authority transact with the hotel partner to generate lodging consumption data, and the goods selling partner transact with goods to generate goods purchasing consumption data. Specifically, the consumption data may be generated by trading with a plurality of partners, or the transaction data may be generated by trading with one partner, which is not limited in the embodiment of the present invention. And then uploading consumption data generated by the transaction to the commodity circulation chain from a transaction node corresponding to the consumption data in the commodity circulation chain by the reimburser and the partner with reimbursement authority, so that the tax invoice chain can obtain the commodity consumption data through the commodity circulation prediction machine node.
In the embodiment of the invention, after the consumption data is generated by the transaction between the reimbursement personnel with reimbursement authority and the partner and is linked up, the fund settlement chain can acquire the consumption data through the node, so that the node can perform fund settlement processing on the consumption data to acquire the fund settlement data, specifically, the fund settlement data can comprise consumption fund data corresponding to the consumption data, tax data corresponding to the consumption funds and the like, and then the fund settlement data is uploaded to the fund settlement chain, so that the tax invoice chain acquires the fund settlement data determined by the consumption data of the article in the fund settlement chain through the fund settlement prompter node.
Step 103: and the reimbursement node in the tax invoice chain processes the consumption data of the articles in the tax invoice chain and the fund settlement data determined by the article consumption data to obtain reimbursement information of the articles, and sends the reimbursement information to the auditing node so as to reimburse the consumption data of the articles.
In the embodiment of the invention, after the reimbursement node processes the consumption data of the goods in the tax invoice chain and the fund settlement data determined by the consumption data of the goods, reimbursement information of the goods can be obtained, and then the reimbursement information can be sent to the auditing node, so that reimbursement of the consumption data of the goods is realized.
In the embodiment of the invention, an audit node in a tax invoice chain audits according to reimbursement information, if the audit is qualified, reimbursement record information is obtained, and the reimbursement record information is uploaded to the tax invoice chain, so that any node in the tax invoice chain obtains the reimbursement record information; and the article consumption data, the fund settlement data and the invoice data corresponding to the reimbursement information in the reimbursement record information correspond to one another and are stored in a tax invoice chain.
For example, the reimbursement record information includes 10 purchased products a, 10 corresponding amounts of the purchased products a being 1500 yuan, the reimburser identifier being F, the time for purchasing 10 products a being 2018, 11/20/16/34/15 sec, the transaction party being 1256 and the invoice number, so that the reimbursement record information is stored in the tax invoice chain: the corresponding amount of 10 purchased products A and 10 purchased products A is 1500 yuan, the identifier of the reimburser is F, the time for purchasing 10 products A is 11 months, 20 th month, 16 th month, 34 min and 15 sec in 2018, the transaction party is 1256 and the invoice number. The tax invoice chain correspondingly stores commodity purchase quantity data, fund settlement data, purchase time data, identifiers of reimbursers and transaction parties and invoice numbers in the chain. In this way, when determining that the information of reimbursement personnel F reimbursement needs to be searched, the reimbursement record information can be correspondingly determined.
In the embodiment of the invention, the article circulation chain, the tax invoice chain and the fund settlement chain satisfy a multi-chain consensus and state synchronization mechanism. Specifically, the basic principle of the consensus mechanism is as follows: and the auditing node in the finance and tax block chain multi-chain system collects reimbursement information corresponding to the article consumption data and the fund settlement data received within a period of time, forms a stored block structure and diffuses the block structure to the finance and tax block chain multi-chain system. Specifically, after receiving the information sent by other nodes, any node compares the received information with the information stored in the node, and sends a confirmed information set to the block chain system to other nodes in the fiscal/taxation block chain multi-chain system. Specifically, the information set at least includes article consumption data, fund settlement data, and invoice data corresponding to reimbursement information, so that, through diffusion iteration of each node in the fiscal/tax block-chain multi-chain system, information in all nodes finally reaches a consensus, and reimbursement record information stored by each node is the same.
In the embodiment of the invention, simply speaking, for the transaction of any tax invoice chain, the corresponding fund settlement transaction and article circulation transaction are used as the input states of consumption, after the tax invoice issuing transaction is completed, the invoicing state of the corresponding fund settlement transaction is locked, namely the reimbursement record information is locked, and cannot be used as the input state of the invoicing transaction any more, and the invoicing state of the corresponding article circulation transaction is also locked, and cannot be used as the input state of the invoicing transaction any more. The multi-chain consensus and the state of the three chains are synchronous, and any node maintaining three accounts at the same time can acquire reimbursement record information. In such a mode, various data information can be locked, the recorded reimbursement information can be unchangeable, and the consistency of tax reimbursement, accounting and deduction is realized, so that the verification of reimbursement data is enhanced.
In the embodiment of the invention, the tax invoice chain in the fiscal block chain multi-chain system can acquire data and information corresponding to reimbursers stored in an article circulation chain and a fund settlement chain in the fiscal block chain multi-chain system, such as the information of commodity quantity purchased by the reimbursers, through a fund settlement preplanning machine node and an article circulation preplanning machine node, and specifically, because the data and information stored in the article circulation chain and the fund settlement chain are stored by adopting a block chain technology, a calculation basis which cannot be falsified and has higher reliability can be provided for reimbursement processing in the tax invoice chain, namely, the tax invoice chain can directly acquire consumption data corresponding to the reimbursers and settlement fund data corresponding to the consumption data, so that the acquired data can be processed without submitting corresponding consumption documents and the like by the reimbursers, thereby improving the efficiency of reimbursement.
