In, invoice issuing side's information may include the Taxpayer Identification Number of invoice issuing side, and invoice reciever information may include invoice
The Taxpayer Identification Number of reciever；Assuming that the user is the invoice reciever of the target invoice, then invoice reciever information can
To include the Taxpayer Identification Number of the user.
After the input that the user completes invoice creation information, which can be generated corresponding invoice request to create,
And the invoice request to create is sent to the node device in the block chain.
Node device in the block chain can carry out the invoice request to create after receiving the invoice request to create
Response.
Specifically, it can first determine whether the invoice creation amount of invoice issuing side corresponding with the invoice request to create fills
Foot.
For example, it can obtain invoice from the invoice creation information that the user in the invoice request to create inputs and open
The Taxpayer Identification Number of tool side, and determine that corresponding invoice issuing side, the invoice issuing side are based on the Taxpayer Identification Number
The corresponding invoice issuing side of invoice request to create.It is subsequent, it can first determine whether the invoice of the invoice issuing side creates amount
It is sufficient.
Wherein, it should be noted that in the present specification, the initial invoice in invoice issuing side creates amount, can be base
What the initial credit scoring in the invoice issuing side was determined.
In a kind of embodiment shown, the intelligent contract being deployed on the block chain can be called by the node device
The amount of middle statement checks logic, determines whether the invoice creation amount of the invoice issuing side is sufficient.
Wherein, amount checks that logic specifically can be statement in the intelligence contract, with the hair for checking invoice issuing side
Ticket creates the relevant program code of execution logic (such as: some program technics or function for calling) of amount.
Alternatively, third-party trusted service can also be called by the node device, which is sent to this
Third-party trusted service.Wherein, third-party trusted service, which can be, is deployed in third-party trusted service equipment, with
Check the relevant program code of execution logic of the invoice creation amount of invoice issuing side.For example, this is third-party credible
Service equipment can be the equipment in tax intraoffice network, it is possible thereby to improve Information Security.
The third-party trusted service can determine whether the invoice creation amount of the invoice issuing side is sufficient, and will determine
As a result it is back to the node device.The node device can be based on the determination that the third-party trusted service returns as a result, determining
Whether the invoice creation amount of the invoice issuing side is sufficient.
Specifically, the third-party trusted service can determine the invoice issuing side invoice create amount abundance when,
The definitive result of the invoice creation amount abundance of the invoice issuing side is returned to the node device.The node device is receiving this
After definitive result, it can determine that the invoice creation amount of the invoice issuing side is sufficient.Alternatively, the third-party trusted service can be with
When the invoice creation amount for determining the invoice issuing side is inadequate, the invoice wound of the invoice issuing side is returned to the node device
Build the insufficient definitive result of amount.The node device can determine the invoice issuing side after receiving the definitive result
It is inadequate that invoice creates amount.
If it is determined that the invoice creation amount of the invoice issuing side is sufficient, then the intelligence being deployed on the block chain can be called
The invoice creation logic stated in energy contract, creates information based on the invoice that user in the invoice request to create inputs, creates mesh
Mark invoice.
Wherein, invoice creation logic specifically can be statement in the intelligence contract, the execution logic with creation invoice
Relevant program code.
It should be noted that the invoice creation amount of the invoice issuing side can be the credit based on the invoice issuing side and comment
Divide determination, the credit scoring of the invoice issuing side then can be the creation record of the invoice based on the invoice issuing side to the invoice
The side of issuing carries out what credit evaluation obtained.
In practical applications, third-party trusted service can be called, which is based on by the third-party trusted service
The invoice creation record for the side of issuing carries out credit evaluation to the invoice issuing side, obtains the credit scoring of the invoice issuing side.
Wherein, third-party trusted service can be the machine learning mould being deployed in third-party trusted service equipment
Type, the machine learning model then can be the machine learning model that Logic Regression Models etc. are usually used in credit evaluation.
On the one hand, the machine learning mould for credit evaluation being deployed in third-party trusted service equipment can be called
Type regard the history invoice creation record of the invoice issuing side prestored as training sample, carries out machine learning training, be somebody's turn to do
The initial credit of invoice issuing side scores.
For example, first the history invoice creation record of the invoice issuing side prestored can be input in assessment system
It is assessed, is obtained several for carrying out the index of credit evaluation to the invoice issuing side.It is subsequent, can based on obtain these
Index and such as invoice issuing side information, invoice reciever information, the amount of invoice, branch in history invoice creation record
The essential informations such as mode, transaction item title, loco, exchange hour are paid to construct forecast sample, and by the prediction of building
Sample is input to the credit evaluation model and carries out credit evaluation, obtains the initial credit scoring of the invoice issuing side.
On the other hand, it after the creation for completing the target invoice, can further generate corresponding to the target invoice
Invoice creation record, and credit evaluation is carried out to the invoice issuing side based on invoice creation record, obtain the invoice issuing side
Credit scoring.
For example, the invoice of generation can be created to record and the history invoice of the invoice issuing side prestored creates
Record, which is all input in assessment system, to be assessed, and is obtained several for carrying out the index of credit evaluation to the invoice issuing side.
It is subsequent, forecast sample can be constructed based on the essential information in obtained these indexs and invoice creation record, and by structure
The forecast sample built is input to the credit evaluation model and carries out credit evaluation, and the credit for obtaining the updated invoice issuing side is commented
Point.
Certainly, in addition to that can be carried out other than credit evaluation by calling third-party trusted service to invoice issuing side,
In practical application, credit evaluation can also be carried out to invoice beginning side by service on the relevant chain of calling.
For example, the relevant machine learning model for being used to carry out credit evaluation can be deployed in block chain (for example, making
To execute logic states in intelligent contract), and then can be by calling the machine learning model being deployed on block chain, to this
Invoice issuing side carries out credit evaluation, and no longer needs by calling third-party trusted service, to the invoice issuing side into
Row credit evaluation.
It can be seen that due to complete target invoice every time creation after, hair corresponding with the target invoice can be based on
Ticket creation record re-starts credit evaluation to the invoice issuing side, is updated to the credit scoring of the invoice issuing side, because
The credit scoring of this invoice issuing side can dynamically update.
In a kind of embodiment shown, which can be by the credit scoring of the invoice issuing side
Return to the node device.The node device is in the credit for receiving the invoice issuing side that the third-party trusted service returns
After scoring, the amount stated in the intelligent contract being deployed in the block chain can be called to determine logic, be based on the credit scoring
It determines the invoice creation amount of the invoice issuing side, and is somebody's turn to do based on the invoice creation amount determined to for amount inspection
The invoice creation amount of invoice issuing side carries out dynamic update.
Wherein, amount determines logic specifically and can be that statement in the intelligence contract, and determination and updates invoice issuing
The relevant program code of execution logic of the invoice creation amount of side.
For example, it can store the correspondence of credit scoring and invoice creation amount as shown in table 1 below in node device
Relationship:
Table 1
Assuming that the credit scoring of the invoice issuing side that the third-party trusted service that the node device receives returns
Initial value be credit scoring 1, then the corresponding relationship according to shown in upper table 1 can determine the invoice creation of the invoice issuing side
Amount is that invoice creates amount 1.Subsequent, which can create the hair that amount 1 checks the invoice issuing side based on invoice
Whether ticket creates amount sufficient.
If determining that the invoice creation amount of the invoice issuing side is sufficient based on invoice creation amount 1, and therefore create
Target invoice 1, then after the creation for completing target invoice 1, which can further be generated corresponding to target invoice 1
Invoice create record, and by the invoice creation record be sent to the third-party trusted service, with third-party credible by this
Service re-starts credit evaluation to the invoice issuing side based on invoice creation record, obtains the new letter of the invoice issuing side
With scoring and return to the node device.
Assuming that the new credit of the invoice issuing side that the third-party trusted service that the node device receives returns
Scoring is credit scoring 2, then the corresponding relationship according to shown in upper table 2, can determine the invoice creation amount of the invoice issuing side
Amount 2 is created for invoice.Subsequent, which will be used for the invoice creation amount of the invoice issuing side of amount inspection by sending out
Ticket creation amount 1 is updated to invoice creation amount 2, i.e. the node device can check that the invoice is opened based on invoice creation amount 2
Whether the invoice creation amount of tool side is sufficient.
Alternatively, also can store pair in credit scoring section and invoice creation amount as shown in table 2 below in node device
It should be related to:
| Credit scoring section 1 | Invoice creates amount 1 |
| Credit scoring section 2 | Invoice creates amount 2 |
| …… | …… |
Table 2
Assuming that the credit scoring of the invoice issuing side that the third-party trusted service that the node device receives returns
Initial value be credit scoring 1, then can first determine that credit scoring section belonging to credit scoring 1 (is assumed to be credit scoring area
Between 1), further according to corresponding relationship shown in upper table 2, can determine that the invoice creation amount of the invoice issuing side is that invoice creates volume
Degree 1.Subsequent, which can create amount 1 based on invoice and check whether the invoice creation amount of the invoice issuing side fills
Foot.
If determining that the invoice creation amount of the invoice issuing side is sufficient based on invoice creation amount 1, and therefore create
Target invoice 1, then after the creation for completing target invoice 1, which can further be generated corresponding to target invoice 1
Invoice create record, and by the invoice creation record be sent to the third-party trusted service, with third-party credible by this
Service re-starts credit evaluation to the invoice issuing side based on invoice creation record, obtains the new letter of the invoice issuing side
With scoring and return to the node device.
Assuming that the new credit of the invoice issuing side that the third-party trusted service that the node device receives returns
Scoring is credit scoring 2, then can first determine credit scoring section belonging to credit scoring 2 (being assumed to be credit scoring section 2),
Further according to corresponding relationship shown in upper table 2, it can determine that the invoice creation amount of the invoice issuing side is that invoice creates amount 2.
Subsequent, which creates amount for the invoice for being used for the invoice issuing side of amount inspection and is updated by invoice creation amount 1
Amount 2 is created for invoice, i.e. the node device can create amount 2 based on invoice and check that the invoice of the invoice issuing side creates volume
Whether degree is sufficient.
It should be noted that the intelligent contract of the invoice creation amount described above for checking invoice issuing side, use
The intelligent contract of invoice creation amount in the intelligent contract of creation invoice, and for determining and updating invoice issuing side can be with
It is integrated into an intelligent contract to be disposed on above-mentioned block chain, can also be used as two different intelligent contracts in the block
It is disposed on chain, this specification is not construed as limiting this.
It, can also be by the letter of the third-party trusted service based on the invoice issuing side in a kind of embodiment shown
Amount is created with the invoice for determining the invoice issuing side that scores, and the invoice of the invoice issuing side determined creation amount is returned
Back to the node device.The node device is in the invoice wound for receiving the invoice issuing side that the third-party trusted service returns
After building amount, amount can be created based on the invoice received, dynamic is carried out to the invoice creation amount of the invoice issuing side
It updates.
After creation due to completing target invoice every time, the credit scoring of the invoice issuing side can be updated,
So as to be updated based on invoice creation amount of the updated credit scoring to the invoice issuing side, therefore the invoice is opened
The invoice creation amount of tool side can dynamically update.
In the above-mentioned technical solutions, when user needs to create invoice corresponding with the invoice issuing side in block chain,
Invoice first can be carried out to the invoice issuing side and create amount inspection, to be filled in the invoice creation amount for determining the invoice issuing side
