The block diagrams shown in the figures are functional entities only and do not necessarily correspond to physically separate entities. I.e. these functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor means and/or microcontroller means.
The flow charts shown in the drawings are merely illustrative and do not necessarily include all of the contents and operations/steps, nor do they necessarily have to be performed in the order described. For example, some operations/steps may be decomposed, and some operations/steps may be combined or partially combined, so that the actual execution sequence may be changed according to the actual situation.
Fig. 1 shows an architecture of a blockchain system applied in the embodiments of the present application. The blockchain system comprises a sub-network 2 of accounting nodes and a sub-network 1 of service nodes. Accounting node subnetwork 2 includes accounting node 21 which consensus and record data blocks onto the block chain. Service node subnetwork 1 includes service node 11, and service node 11 may validate data blocks recorded by the accounting node onto the blockchain, or may request corresponding transaction data from the accounting node.
Specifically, the service node 11 verifying the data blocks recorded by the accounting node to the blockchain may include the following steps: an accounting node 21 in the accounting node sub-network generates a signature based on transaction information to be included in a data block to be added to the block chain using a key specific to the accounting node; the accounting node 21 adds the transaction information and the generated signature to the data block and adds the data block to a block chain; the accounting node 21 sends the signature to the service nodes in the service node sub-network, and the service nodes verify the signature according to the key specific to the accounting node, so that the service node 11 verifies the data blocks recorded by the accounting node to the block chain. The accounting nodes in the accounting node sub-network are responsible for recording data blocks to the block chain, and the service nodes in the service node sub-network are responsible for witnessing the results recorded by the accounting nodes. Specifically, the accounting node generates a signature based on transaction information to be included in a data block to be added to a block chain, and then adds the transaction information and the generated signature to the data block for uplink. The signature is sent to a service node in the service node subnetwork so that the service node performs signature verification on the signature according to a key specific to the accounting node. The service nodes in the service node sub-network can witness the transaction data of the whole network by verifying the signature of the accounting node on the block. Billing networks, while having monopoly billing rights, are publicly traceable in all activities because the data blocks have digital signatures representing the identity of the billers. If the billing nodes do dislike collectively, then evidence that a particular billing node does dislike will be retained by all nodes in the witness network. Compared with the traditional centralized system and the private chain, the system runs more transparently in the scheme; compared with the traditional decentralized common-chain scheme, the scheme is more controllable and more convenient to supervise.
In an embodiment of the application, the connection between the billing node sub-network 2 and the service node sub-network 1 may be via a proxy node 12, which proxy node 12 may be a service node of the service node sub-network 1, which is responsible for transferring information to be transferred by the billing node 21 to the service node 11. The service node 11 is a terminal of a transaction party that generates various transaction data to be linked, and may also be a terminal that inquires the transaction data from the sub-network 2 of the accounting node. The transaction data generated by the service node 11 is transmitted to the accounting node 21 through the proxy node 12, and then is recorded on the blockchain after being identified, which is beneficial to the uniform processing and supervision of the transaction data, and the service node 11 can also perform the uplink supervision and witness of the transaction data through the information sent by the accounting node 21 through the proxy node 12, which has very important significance in some scenes that need uniform supervision but also afraid collective cheating of the supervised nodes and therefore need supervision.
In the configuration shown in fig. 1, the service node sub-network 1 adopts a P2P network mode. A P2P network is a distributed application architecture that distributes tasks and workloads among peers (peers), and is a form of networking or network formed by Peer-to-Peer computing models at the application layer, i.e., "Peer-to-Peer" or "Peer-to-Peer" networks. It can be defined as: participants of the network share a portion of the hardware resources (processing power, storage power, network connectivity, printers, etc.) they own, which provide services and content over the network and which can be accessed directly by other peer nodes without going through intermediate entities. Participants in this network are both providers and acquirers of resources, services and content. Therefore, in the service node subnetwork 1, when the proxy node 12 receives the message transmitted from the accounting node 21, the message is transmitted to the surrounding service nodes 11, and the surrounding service nodes 11 receive the message and transmit the message to the surrounding service nodes 11, so that the message is transmitted between each service node 11 of the service node subnetwork 1.
Fig. 2 shows an architecture of another blockchain system applied in the embodiment of the present application. This architecture differs from the architecture shown in fig. 1 in that: the P2P network mode is not adopted in the service node subnetwork 1, but the mode of the broadcast network is adopted. In particular, proxy node 12, upon receiving the message passed from accounting node 21, broadcasts the message to other service nodes 11 in service node subnetwork 1. In this way, the propagation of the message between each service node 11 of the service node subnetwork 1 is also achieved.
Fig. 3 shows an architecture of another blockchain system applied in the embodiment of the present application. This architecture differs from that shown in fig. 1 in that: the billing node sub-network 2 is divided into a plurality of branch billing node sub-networks. Each branch accounting node sub-network may be responsible for the recording of some type of transaction information. For example, a business may have a supply chain financial transaction and may need to record contract information, credit, etc. generated during supply and marketing to the blockchain, and the business may need to issue invoices and also record invoicing information, invoice reimbursement information, etc. to the blockchain. In this case, in order to facilitate the requirement that the accounting node is supervised by the same department, the accounting node for recording the supply chain financial service transaction and the accounting node for recording the transaction in the invoice circulation process are respectively assigned to different departments. For example, the accounting node for recording the supply chain financial service transaction is an accounting terminal set by a bank, and the accounting node for recording the transaction in the invoice circulation process is an accounting terminal set by a national tax bureau. And supply chain financial transaction and recording of transactions in the invoicing process may also end up being recorded on a different branch of the billing node sub-network. In this case, the agent node 12 transmits the transaction information to the branch accounting node sub-network corresponding to the transaction type, based on the transaction type carried in the transaction information transmitted from the service node 11.
It should be noted that, in the architecture of the blockchain system shown in fig. 1 to 3, the proxy node 12 is located in the service node sub-network 1, and in other embodiments of the present application, the proxy node 12 may also be located in the common node sub-network 2, or may be independent of the service node sub-network 1 and the common node sub-network 2.
The architecture of the blockchain system shown in fig. 1 to 3 can be applied to the application scenario of electronic invoices, and is described in detail as follows:
in one embodiment of the application, the accounting nodes in the sub-network of accounting nodes may be respective terminals of the tax administration, for example, the sub-network of accounting nodes is formed by using the terminals of the tax administration deployed in a plurality of regions as one accounting node respectively. Each service node in the service node sub-network may be a local tax office terminal, an invoicing agent facilitator terminal, an invoicing enterprise terminal, an individual user terminal, etc.
The intelligent contracts in the accounting node sub-networks store control logics of tax management, such as information which can be accessed by various service nodes (such as the tax-saving bureau can access invoice information related to the province, the city tax bureau can only access invoice information related to the city, the district tax bureau can only access invoice information related to the district, the billing agent service provider can only access invoice information related to enterprises of which the agent is the agent, and the like), the total amount of tax invoices, the total amount and the like which can be invoiced in a single period. When the accounting node in the accounting node sub-network receives a tax information processing request (such as an electronic invoice query request) sent by a service node in the service node sub-network, the authority data of the service node is determined according to the intelligent contract stored in the accounting node sub-network, the tax information processing request is responded according to the authority data, and a response result to the tax information processing request is returned to the service node. Therefore, the technical scheme of the embodiment of the application can conveniently manage various control logics in the tax information processing process through the intelligent contract, and effectively improve the efficiency of tax information management.
The following describes details of implementation of the tax administration scheme based on the blockchain system according to the embodiment of the present application:
fig. 4 schematically shows a flow chart of a method of tax management based on a blockchain system according to an embodiment of the present application, as shown in fig. 1 to 3, the blockchain system comprising a billing node sub-network 2 and a service node sub-network 1, the billing node sub-network 2 comprising a billing node 21 and the service node sub-network 1 comprising a service node 11. The data management method of the blockchain system shown in fig. 4 may be performed by accounting node 21 in accounting node sub-network 2. Referring to fig. 4, the method for managing taxation based on the blockchain system at least includes steps S410 to S430, which are described in detail as follows:
in step S410, a tax information processing request sent by a service node in a service node sub-network is received.
In an embodiment of the present application, the service node in the service node sub-network may directly send the tax information processing request to the accounting node in the accounting node sub-network, or may first send the tax information processing request to the proxy node, and the proxy node forwards the tax information processing request to the accounting node. The tax information processing request can be an invoice information query request, an invoice information issuing request, an invoice reimbursement request and the like.
In step S420, the authority data of the service node is obtained according to the intelligent contract related to tax administration stored in the sub-network of the accounting node.
In an embodiment of the application, the rights data set by the intelligent contracts related to tax administration stored in the sub-networks of accounting nodes for different types of service nodes may not be the same. The concrete description is as follows:
in an embodiment of the present application, when a service node is a tax authority node, the permission data of the tax authority node obtained according to the intelligent contract includes one or more of the following: the total amount of the tax invoices which can be issued in a single period, the maximum amount of the single tax invoices which can be issued by the tax agency, an enterprise which can be inquired about tax related information by the tax agency and an enterprise tax agency service side which can be inquired about the tax related information by the tax agency.
In an embodiment of the present application, when the business node is an enterprise tax agency service node, the authority data of the enterprise tax agency service node obtained according to the intelligent contract includes one or more of the following authority data: the enterprise managed by the enterprise tax agency service side and the enterprise which can be inquired about tax related information by the enterprise tax agency service side.
In an embodiment of the present application, when the service node is an enterprise node, the obtained authority data of the enterprise according to the intelligent contract includes information of a ticket that the enterprise can query and/or process. Similarly, if the service node is an individual, the authority data of the individual acquired according to the intelligent contract also includes information of the ticket that the individual can query and/or process.
In step S430, the tax information processing request is responded according to the authority data of the service node, and a response result for the tax information processing request is returned to the service node.
In an embodiment of the application, if the tax information processing request is an invoice issuing request, the total amount and/or total amount of the tax invoices which can be issued by the service node in a single period, the maximum amount of a single tax invoice and other checking logics can be determined according to authority data of the service node, and then the invoice issuing request is responded based on a checking result.
In an embodiment of the present application, if the tax information processing request is an inquiry request for specified tax information, it may be determined whether the service node has an authority to access the specified tax information and a specific authority level according to authority data of the service node, and when the service node has an authority to access the specified tax information, data that can be accessed by the service node is returned to the service node according to the authority level of the service node.
In one embodiment of the present application, there may be a hierarchical relationship between the various service nodes in the service node sub-network. For example, the lower level of the tax administration includes each provincial tax administration; the lower level of the provincial tax bureau comprises various city tax bureaus; the lower level of the city tax bureau comprises various district tax bureaus; the lower level of the district tax bureau comprises enterprises, individuals, billing agent service providers and the like; the lower level of the billing agent service provider includes the business or individual, etc. of its agent. Due to the hierarchical relationship, the information accessible by the service nodes of different levels and the tax information capable of being processed are different, for example, the tax administration can inquire the full electronic invoice information, the provincial tax administration can check the electronic invoice information of the province, the city tax administration can check the electronic invoice information of the whole city, an individual or an enterprise can only check the electronic invoice information related to the individual or the enterprise, and the invoicing agent service provider can check the electronic invoice information of the enterprise or the individual and the like of the agent.
In the related art, due to the existence of the above hierarchical relationship, the upper level service node needs to maintain a relationship with the lower level service node. For example, the billing agent service provider needs to maintain information about the enterprises or individuals that it acts on, and assuming that the number of billing agent service providers is n and the number of enterprises or individuals that each billing agent service provider maintains is m, a relation table of m × n size is generated, and the data size of the relation table is doubled as n and m increase. In order to solve the problem, the embodiment of the present application provides a technical solution for improving an address structure of a service node, that is, adding identification information of an upper node to which the service node belongs and signature information of the upper node to address information of the service node, specifically as shown in fig. 5, the address information of the service node includes a parent number, a public key hash of the service node, and a parent signature. The parent number represents the identification information of the superior node to which the service node belongs; the hash of the public key of the self public key represents the identification information of the service node; the parent signature represents signature information of a superior node to which the service node belongs, and the signature information is used for verifying the identity of the service node.
Based on the above address structure, in an embodiment of the present application, if the tax information processing request is a tax information query request, the service node may add its address information to the transmitted tax information query request, and then after receiving the tax information query request, the accounting node may determine, according to the address information included in the tax information query request, an upper node to which the service node belongs, and verify, according to the upper node to which the service node belongs, the signature information included in the tax information query request, and if the signature information included in the tax information query request passes verification, based on the authority data of the service node, query and acquire, in the tax data corresponding to the upper node to which the service node belongs, the tax information that the service node is entitled to acquire. Therefore, in the embodiment of the application, by improving the address structure of the service node, the relationship table between the superior node and the subordinate node does not need to be maintained, and the storage cost of the relationship table can be further reduced.
In the embodiment of the present application, a technical solution for updating the above intelligent contract related to tax administration is also provided, and the detailed description is as follows:
as shown in fig. 6, the process of updating an intelligent contract related to tax administration according to an embodiment of the present application includes the following steps S610, S620, and S630, which are specifically described as follows:
in step S610, transaction data for updating the smart contract is generated.
In one embodiment of the application, since the updating of the intelligent contract requires consensus among the accounting nodes in the accounting node sub-network, corresponding transaction data may be generated according to the new intelligent contract and then issued to the accounting node sub-network for consensus processing, for example, transaction data for updating the intelligent contract may be generated by using the intelligent contract before updating as an input of the transaction and the intelligent contract after updating as an output of the transaction.
In one embodiment of the present application, as shown in FIG. 7, a process for generating transaction data for updating a smart contract according to one embodiment of the present application includes the steps of:
step S710, receiving an update message of an access control policy for the tax information processing request sent by a designated service node.
In one embodiment of the present application, the designated service node may be any service node in the service node sub-network, or may be a service node configured to update the intelligent contract.
Step S720, the appointed service node is authenticated.
In the embodiment of the application, since the intelligent contract is used for managing and controlling the tax information, in order to avoid that an illegal node arbitrarily initiates the update process of the intelligent contract, the authentication process needs to be performed on the designated service node which sends the update message.
Step S730, if the designated service node passes the authentication, generating the transaction data according to the update message.
In one embodiment of the application, where the business node is a tax authority node, the transaction data used to update the intelligent contract may include information to add and/or delete an enterprise tax agency service party managed by the tax authority.
In one embodiment of the present application, in the case that the business node is an enterprise tax agency server node, the transaction data for updating the intelligent contract may include information for adding and/or deleting enterprises that the enterprise tax agency server needs to proxy for.
In one embodiment of the present application, where the business node is a business node, the transaction data used to update the intelligent contract may include information on instruments that the business is able to query and/or process.
In step S620, the transaction data is transmitted to other accounting nodes in the accounting node sub-network for consensus of the transaction data in the accounting node sub-network.
In one embodiment of the present application, fig. 8 shows a process of broadcasting, by the leading accounting node, the data block containing the transaction data that needs to be identified to other accounting nodes in the accounting node sub-network for identification, according to the embodiment of the present application. The client (which may be a billing node forming a data block to be recorded on the block chain) initiates a consensus request and sends the consensus request to a leader billing node a in a leader state; continuing to enter an entity adding stage, and broadcasting the data block corresponding to the consensus request to other accounting nodes (accounting nodes B, C and D \8230; which are not in a leader state) in an accounting node sub-network by the leader accounting node A; and continuing to enter an additional response stage, broadcasting the received common identification contents to other accounting nodes by other accounting nodes, entering a confirmation stage when the common identification contents broadcast by the other accounting nodes with the preset number (2f + 1) are consistent, and feeding back a confirmation result to the leader accounting node A by each accounting node. And when the leader accounting node A receives the feedback confirmation of other block chain nodes with the preset number (2f + 1), judging that the consensus is completed and feeding back the consensus completion result to the client. Where f is the largest integer less than (N-1)/3 and N is the number of accounting nodes in the accounting node subnetwork. f is the number of bad accounting nodes in the sub-network of accounting nodes that the algorithm can tolerate. When the consensus succeeds, each accounting node in the accounting node subnetwork can add the data block to the block chain, i.e. the uplink is completed.
