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 application, 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 embodiments herein, 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 application in the case that service node is taxation authority's node, 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 application 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 application in the case that service node is enterprise's node, 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, can basis if tax information processing request is the request to issue invoice in one embodiment of the application
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 application, 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 data being able to access that are back to the service node.
In one embodiment of the application, there may be level between each service node in service node sub-network
Relationship.For example the junior of State Administration of Taxation includes each province's tax office；The junior of tax office, province includes each city's tax office；The junior of tax office, city
Including each area's tax office；The junior of tax office, area includes enterprise, individual, agency service of making out an invoice quotient etc.；Under agency service of making out an invoice quotient
Grade includes enterprise or individual of its agency etc..Due to this hierarchical relationship, so that the addressable letter of the service node of different levels
The tax information for ceasing and being capable of handling is not identical, for example, State Administration of Taxation can inquire the electronic invoice information of full dose, tax office, province can
It can be checked with checking that the electronic invoice information of this province, tax office, city can check citywide electronic invoice information, individual or enterprise only
Electronic invoice information relevant to oneself, agency service of making out an invoice quotient can check the enterprise of its agency or the electronic invoice letter of individual
Breath etc..
In the related art, due to the presence of above-mentioned hierarchical relationship, so that higher level's service node needs to safeguard and junior's industry
Relationship between business node.For example the agency service quotient that makes out an invoice needs to safeguard the enterprise of its agency or the information of individual, it is assumed that makes out an invoice
The quantity of agency service quotient is n, and the enterprise of each agency service quotient maintenance of making out an invoice or personal quantity are m, then one can be generated
The relation table of a m × n size, with the increase of n and m, the size of data of the relation table will double.It is asked to solve this
It inscribes, proposes the technical solution improved to the address structure of service node in the embodiment of the present application, i.e., in service node
The identification information of the superior node belonging to it and the signing messages of superior node are added in address information, specifically as shown in figure 5, industry
Business address of node information includes parent number, the public key Hash of itself and parent signature.Wherein, parent number indicates the business
The identification information of superior node belonging to node；The public key Hash of itself indicates the identification information of the service node itself；Parent
Signature indicates the signing messages of superior node belonging to the service node, the signing messages be used for the identity of the service node into
Row verifying.
Based on above-mentioned address structure, in one embodiment of the application, if tax information processing request is tax letter
Inquiry request is ceased, then service node can add its address information in the tax information inquiry request of transmission, and then section of keeping accounts
Point, can the letter of the address according to included in the tax information inquiry request after receiving the tax information inquiry request
Breath determines superior node belonging to the service node, and the superior node according to belonging to the service node inquires tax information
Signing messages included in request is verified, if verifying to signing messages included in the tax information inquiry request logical
It crosses, then based on the permissions data of the service node, is inquired in the corresponding tax data of the superior node belonging to the service node
And obtain the service node have the right obtain tax information.As it can be seen that passing through the address of improvement service node in the embodiment of the present application
Structure, so that the relation table between Maintenance free superior node and downstream site, and then the carrying cost of relation table can be reduced.
