Fig. 1 shows a kind of architecture of block catenary system applied by the embodiment of the present invention.Block catenary system includes Accounting nodes sub-network 2 and service node sub-network 1.Accounting nodes sub-network 2 includes carrying out knowing together and counting to data block The accounting nodes 21 on block chain are recorded according to block.Service node sub-network 1 includes service node 11, and service node 11 can be with The data block that accounting nodes are recorded on block chain is verified, or can request corresponding number of deals to accounting nodes According to.
Specifically, service node 11 to the data block that accounting nodes are recorded on block chain carry out verifying may include with Lower step: accounting nodes 21 in accounting nodes sub-network are using the key specific to the accounting nodes, based on adding The Transaction Information to be included in a data block on to block chain generates signature；Accounting nodes 21 believe the transaction The data block is added in breath and the signature generated, is added on block chain；The signature is sent to the industry by accounting nodes 21 Service node in node sub-network of being engaged in, service node are signed according to the key pair specific to the accounting nodes Verifying, is verified with the data block for realizing that accounting nodes are recorded on block chain in service node 11.Accounting nodes subnet Accounting nodes in network are responsible for block chained record data block, and the service node in service node sub-network is responsible for witness book keeping operation The result of nodes records.Specifically, accounting nodes based on being included in a data block on block chain to be added to Transaction Information generates signature, and the data block then is added in the Transaction Information and the signature of generation, carries out cochain.Institute The service node that signature is sent in the service node sub-network is stated, makes service node according to the key specific to the accounting nodes Signature verification is carried out to the signature.Service node in service node sub-network can by accounting nodes signature on verifying block It is witnessed with the transaction data to the whole network.Although book keeping operation network possesses the book keeping operation power of monopolization, but because data block has Represent the digital signature of book keeping operation person's identity, thus all behaviors be all disclose it is retrospective.If accounting nodes collective does evil, that Whole nodes in witness network all say the evidence that will be remained with specific accounting nodes and do evil.Compared to conventional center system and Privately owned chain, in this scheme, the operating of system is more transparent；And traditional decentralization public affairs chain scheme is compared, this programme More controllably also it is more convenient for supervise.
In one embodiment of the invention, generation can be passed through between accounting nodes sub-network 2 and service node sub-network 1 It manages node 12 to connect, agent node 12 can be a service node of service node sub-network 1, be responsible for accounting nodes 21 Service node 11 is passed to the information that service node 11 transmits.Service node 11 is to generate the various transaction data for needing cochain Counterparty terminal, be also possible to from accounting nodes sub-network 2 inquire transaction data terminal.What service node 11 generated Transaction data is being transmitted to accounting nodes 21 by agent node 12, is then recorded on block chain, is conducive to after common recognition Transaction data being uniformly processed and supervising, and service node 11 can also be sent by accounting nodes 21 via agent node 12 Information carry out transaction data cochain supervision and witness, this it is certain both needed unified supervision but be afraid of supervision node collection Body cheating thus need to be of great significance in the scene supervised.
In the construction shown in fig. 1, service node sub-network 1 uses P2P network mode.P2P network is one kind in equity Between person (Peer) distribute task and workload Distributed Application framework, be P2P computing model formed in application layer one Kind networking or latticed form, i.e. " point-to-point " or " end-to-end " network.It can be with is defined as: the participant of network shares them A part of hardware resource (processing capacity, storage capacity, network-connectivity, printer etc.) possessed, these shared resources By network offering services and content, can directly be accessed by other peer nodes without being subjected to intermediate entities.In this network Participant be both that the supplier and resource of resource, service and content, service and content obtain taker.Therefore, in business section In point sub-network 1, after agent node 12 is received from the message that accounting nodes 21 pass over, peripherad service node 11 It is propagated, the service node 11 of surrounding receives the message, then transmits to surrounding service node 11, has reached the message Propagation between each service node 11 of service node sub-network 1.
Fig. 2 shows the architectures of another kind block catenary system applied by the embodiment of the present invention.The architecture with Architecture shown in Fig. 1 the difference is that: do not take P2P network mode in service node sub-network 1, but adopt Take the mode of broadcasting network.Specifically, agent node 12 is receiving after the message that accounting nodes 21 pass over, this is disappeared Cease the other service nodes 11 being broadcast in service node sub-network 1.In this way, also achieving the message in service node sub-network Propagation between 1 each service node 11.
Fig. 3 shows the architecture of another kind block catenary system applied by the embodiment of the present invention.The architecture with Architecture shown in FIG. 1 the difference is that: its accounting nodes sub-network 2 is divided into multiple branch's accounting nodes sub-networks. Each branch's accounting nodes sub-network can be responsible for the record of the Transaction Information of a certain seed type.For example, a certain enterprise may have There is supply chain financial business, it may be necessary to the contract information generated during supply and marketing, the payment for goods such as buy on dredit information and block is recorded On chain, while the enterprise will also issue invoice, and also information of making out an invoice, invoice reimbursement information etc. are recorded on block chain.At this moment, In order to be conducive to the needs that accounting nodes are supervised by same department, may record supply chain financial business transaction accounting nodes and The accounting nodes of transaction during record invoice circulation will belong to different departments.For example, record supply chain financial business is handed over Easy accounting nodes are the accounting terminal of bank's setting, and the accounting nodes for recording the transaction during invoice circulation are Administration of State Bureau The accounting terminal of setting.And the transaction during supply chain financial business transaction and record invoice circulation also may finally will record In the accounting nodes sub-network of different branches.At this moment, agent node 12 will be according to the Transaction Information sent from service node 11 The type of transaction of middle carrying sends the Transaction Information in branch's accounting nodes sub-network corresponding with the type of transaction.
It should be noted that agent node 12 is located at industry in the architecture of Fig. 1 to block catenary system shown in Fig. 3 In node sub-network 1 of being engaged in, in other embodiments of the invention, agent node 12 can also be located in common recognition node sub-network 2, Or independently of service node sub-network 1 and common recognition node sub-network 2.
The architectural framework of block catenary system shown in Fig. 1 to 3 can be applied in the application scenarios of electronic invoice, below in detail Carefully it is illustrated:
In one embodiment of the invention, it is whole to can be each State Administration of Taxation for the accounting nodes in accounting nodes sub-network End, such as State Administration of Taxation's terminal by being deployed in multiple areas constitute accounting nodes subnet respectively as an accounting nodes Network.Each service node in service node sub-network can be local tax office terminal, agency service of making out an invoice quotient terminal, enterprise of making out an invoice Industry terminal, personal user's terminal etc..
Intelligent contract in accounting nodes sub-network stores the control logic of tax administration, such as various types of business (such as province's tax office is able to access that invoice information relevant to this province, tax office, city can only access and this city to the information that node is able to access that Relevant invoice information, tax office, area can only access invoice information relevant to local area, agency service of making out an invoice quotient can only access its generation Relevant invoice information of the enterprise of reason etc.), total quantity, total amount of tax invoice etc. can be issued in signal period.Work as book keeping operation Accounting nodes in node sub-network receive the tax information processing request of the transmission of the service node in service node sub-network After (inquiry request of such as electronic invoice), which is determined according to the above-mentioned intelligent contract stored in accounting nodes sub-network Permissions data, and then according to the permissions data respond the tax information processing request, and will to the tax information processing request Response results return to the service node.As it can be seen that the technical solution of the embodiment of the present invention can be by intelligent contract easily Various control logics in control of the government revenue information process, effectively increase the efficiency of tax information management.
The realization details of the tax administration scheme based on block catenary system of the embodiment of the present invention is explained in detail below It states:
Fig. 4 diagrammatically illustrates the tax administration method according to an embodiment of the invention based on block catenary system Flow chart, as shown in Figure 1 to Figure 3, the block catenary system include accounting nodes sub-network 2 and service node sub-network 1, book keeping operation section Point sub-network 2 includes accounting nodes 21, and service node sub-network 1 includes service node 11.The number of block catenary system shown in Fig. 4 It can be executed by the accounting nodes 21 in accounting nodes sub-network 2 according to management method.Referring to shown in Fig. 4, block chain should be based on The tax administration method of system includes at least step S410 to step S430, is described in detail as follows:
In step S410, receives the tax information that the service node in service node sub-network is sent and handle request.
In one embodiment of the invention, the service node in service node sub-network can be directly to accounting nodes Accounting nodes in network send tax information processing request, tax information processing request first can also be sent to agency's section Tax information processing request is forwarded to accounting nodes by agent node by point.Wherein, tax information processing request can be hair Ticket information inquiring request, invoice information issue request, invoice reimbursement request etc..
In the step s 420, according to the intelligent contract relevant to tax administration stored in the accounting nodes sub-network, Obtain the permissions data of the service node.
In an embodiment of the present invention, the intelligent contract relevant to tax administration stored in accounting nodes sub-network is directed to Permissions data set by different types of service node may be different.It is described as follows:
In one embodiment of the invention, it in the case that service node is taxation authority's node, is intelligently closed according to this The permissions data of the taxation authority's node about got, including following one or more: the tax can be issued in signal period The total amount of tax invoice can be issued in the total quantity of invoice, signal period, individual tax that the taxation authority can issue Be engaged in invoice maximum dollar amount, can by the taxation authority inquire tax relevant information enterprise, can be by the taxation authority Inquire the business taxation agency service side of tax relevant information.
In one embodiment of the invention, in the case that service node is business taxation agency service side node, root According to the permissions data for the business taxation proxy service node that the intelligence contract is got, including following one or more permission numbers According to: by the enterprise of business taxation agency service square tube reason, tax phase can be inquired by the business taxation agency service side Close the enterprise of information.
In one embodiment of the invention, it in the case that service node is enterprise's node, is obtained according to the intelligence contract The permissions data of the enterprise got includes the information for the bill that enterprise can inquire and/or handle.Similarly, if service node It is personal, then also including that individual can inquire and/or handle according to the personal permissions data that the intelligence contract is got The information of bill.
In step S430, the tax information processing request is responded according to the permissions data of the service node, and will The service node is back to for the response results of tax information processing request.
It in one embodiment of the invention, can basis if tax information processing request is the request to issue invoice The permissions data of service node determine the service node can be issued in signal period tax invoice total quantity and/or total gold The check logics such as maximum dollar amount of volume, individual tax invoice, and then the request to issue invoice is responded based on check results.
In one embodiment of the invention, if tax information processing request is to be directed to that the inquiry of tax information is specified to ask It asks, then can determine whether the service node has permission to access the specified tax information and tool according to the permissions data of service node The Permission Levels of body, when the service node Internet access specified tax information, then according to the Permission Levels of the service node The data being able to access that are back to the service node.
