Wherein, it should be noted that transaction (Transaction) described in this specification refers to and passes through block
The client of chain creates, and a data for needing finally to be distributed in the distributed data base of block chain.
Usually there is point of the transaction of narrow sense and the transaction of broad sense in the transaction in block chain.The transaction of narrow sense refers to use
The value Transfer that family is issued to block chain；For example, transaction can be user and exist in traditional bit coin block chain network
One initiated in block chain transfers accounts.And the transaction of broad sense refers to the industry being intended to business that user issues to block chain
Business data；For example, operator can build alliance's chain based on actual business demand, rely on the deployment of alliance's chain it is some with
Unrelated other types of line service (for example, depositing card business, authenticity verification business, invoice rushes red business etc.) of value Transfer,
And in this kind of alliance's chain, service message that transaction can be that user issues in alliance's chain one is intended to business or
Service request.
Above-mentioned client may include any type of underlying services data stored using in block chain as data branch
Support, to realize the upper layer application of specific business function.
In block chain technology, block chain interior joint carries out operation to block and usually requires to rely on corresponding intelligent contract
(Smart contract).Such as the operations such as storage, modification, deletion are required to rely on intelligent contract in block chain.The intelligence
Can contract can be it is a kind of be intended to apply contract is propagated, verified or executed in a manner of information-based can be deployed on block chain
Computer protocol.By stating that service logic may be implemented to execute corresponding operating in intelligent contract.Intelligent contract allows
Do not have to carry out credible transaction in third-party situation.These transaction are traceable and irreversible.Intelligent contract, which is capable of providing, to be better than
The safety of traditional contracts method, and reduce other transaction costs relevant to contract.In general, intelligent contract can be and be deployed in area
Block chain node is local, can call corresponding intelligent contract when node needs to be implemented some movement, run intelligent contract with
The service logic stated in intelligent contract is executed, to obtain implementing result.
Digital digest described in this specification can refer to that (hash also referred to as dissipates based on initial data progress Hash
Column) calculate after obtained hash value.Specifically, the digital digest of the invoice includes:
For the invoice content of the invoice；It is calculated alternatively, the unique information in the invoice content carries out hash
The hash value arrived.
Wherein, the invoice content may include unique information.For example, invoice content may include invoice number, hair
Ticket code；Usual invoice number and invoice codes are unique informations；Corresponding, the digital digest of invoice can be denoted as hash
(invoice number+invoice codes).Certainly, invoice content can also include nonuniqueness information, such as the date of invoice, be free of tax
Volume；Corresponding, the digital digest of invoice can be denoted as hash (invoice number+invoice codes+date of invoice+be free of tax
Volume).
Correspondingly, described to rush the red invoice content requested including described wait rush red invoice；Alternatively, in the invoice content
Unique information；
Wait rush the digital digest of red invoice described in the calculating, comprising:
Obtain the invoice content wait rush red invoice rushed in red request；Alternatively, in the invoice content
Unique information；
For the invoice content described in getting wait rush red invoice；Alternatively, the uniqueness in the invoice content is believed
Breath carries out hash and hash value is calculated.
It is noted that invoice to be identified and invoice are all made of identical hash algorithm.
As previously mentioned, invoice can be carried out cochain in advance by this specification, in one embodiment, the method also includes:
Receive the invoice request to create that client is submitted；Wherein, the invoice request to create includes the invoice of user's input
Create information；
In response to the invoice request to create, the invoice creation for calling publication to state in the intelligent contract on block chain is patrolled
Volume, information creating invoice is created based on the invoice；And
The digital digest of the invoice is calculated, and by the corresponding relationship of the invoice and the digital digest of the invoice in institute
It states and is stored in block chain.
It is illustrated below in conjunction with the schematic diagram of invoice cochain shown in Fig. 2:
In the present embodiment, user can pass through client used in it when needing to create invoice in the block chain
End initiates one for creating the transaction of invoice, i.e., initiates invoice request to create by client.Specifically, which can lead to
The invoice creation page for crossing client offer inputs the invoice creation information of target invoice to be created；For example, the lift of invoice
The information such as head, the amount of money.After the input that the user completes invoice creation information, which can be based on the invoice of user's input
Information is created to generate corresponding invoice request to create, and the node that the invoice request to create is sent in the block chain is set
It is standby.
Node device in the block chain can carry out the invoice request to create after receiving the invoice request to create
Response.The invoice creation logic for calling publication to state in the intelligent contract on block chain, based in the invoice request to create
Invoice create information creating invoice；And after completing invoice creation, the digital digest of the invoice can be further calculated,
And the corresponding relationship of the invoice and the digital digest of the invoice is stored in the block chain.
In one embodiment, in response to the node device of the invoice request to create, it can also first determine and be created with the invoice
It builds and requests the invoice creation amount of corresponding invoice issuing side whether sufficient.
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.
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.
In another embodiment, the invoice can be by be originally generated invoice mechanism provide.Such as can be by
First invoice data of invoice is directly or indirectly uploaded to block chain by the national taxation bureau.Specifically, when an equipment of drawing a bill is opened
Has an a/d, which is also recorded in the system of the tax bureau, and the tax system of the tax bureau can synchronize will be on invoice
Chain deposits card.Wherein the cochain deposit card process embodiment as previously described it is identical, be not discussed here.
For example, after invoice A, invoice B and invoice C cochain, can have been recorded in block chain invoice A hash and
The mapping relations of invoice A data；The mapping relations of invoice B hash and invoice B data；Invoice C hash and invoice C data reflect
Penetrate relationship.
It is noted that as described in Figure 2, space and the storage red ticket of storage invoice can be divided in block chain
The space of (rushing red invoice).By establishing corresponding relationship to realize that it is red that invoice rushes between invoice and red ticket.
Invoice rushes red process in this specification introduced below:
User discovery invoice exist mistake after, need to carry out the incorrect invoice stored in block chain to rush it is red with offset should

Invoice to be identified rush red.
In one implementation, such as preceding creation invoice is similar, and user can be inputted on the client wait rush red hair
The invoice content of ticket or the unique information in invoice content (are below believed the uniqueness in invoice content or invoice content
Breath is referred to as invoice data), and the invoice data of input is carried and is rushed in red request what client was sent；It is sent to block chain
In node device, come trigger the node device in block chain call deployment intelligent contract, for invoice to be identified carry out
It rushes red.Therefore, block chain interior joint equipment can directly receive invoice data.
In another implementation, user, which can treat, rushes red invoice and takes pictures, and acquires wait rush red invoice
Invoice image, and image recognition is carried out to collected invoice image on the client or in third party's identifying system, to know
Not Chu invoice data, and the invoice data obtained by image recognition is carried and is rushed in red request what client was sent, transmission
To the node device in block chain, to trigger the intelligent contract that the node device in block chain calls deployment, for be identified
Invoice rush red.Therefore, block chain interior joint can directly receive invoice data.
Wherein, image recognition is carried out to the image data of collected invoice, it specifically can be by being deployed in block chain
Intelligent contract is completed, and can also be completed by calling third-party trusted service.
In one implementation, according to image recognition algorithm, the invoice data in the invoice image is identified.The embodiment
In, intelligent contract itself has the contract logic of image recognition, can locally identify the invoice number in invoice image in node
According to.
In another implementation, the method also includes:
Node device can also will be prevented by calling third-party trusted service (such as third-party image recognition mechanism)
Invoice image in pseudo- checking request is sent to third party's trusted service, the image recognition by third party's trusted service based on carrying
Algorithm carries out image recognition to invoice image and obtains above-mentioned invoice data, and the available third party's image of node device
The invoice data that identification mechanism returns.In the embodiment, third party's image recognition mechanism image recognition can be transferred to complete, from
And reduce the requirement (and not all node can have image recognition needed for computing resource) to joint behavior.
In one embodiment, node device can call publication in area after getting and rushing the invoice data in red request
The invoice validation logic stated in intelligent contract on block chain, calculating is described wait rush the digital digest of red invoice, and inquires institute
It states and whether stores target invoice corresponding with the digital digest in block chain.
The embodiment, which calculates the digital digest wait rush red invoice, to be calculated based on intelligent contract, is needed

Relationship is stored in the block chain；
Establish the mapping between the digital digest of the negative amount of money invoice, the target invoice and the target invoice
Relationship, and the mapping relations are stored in the block chain.
The invoice that keeps accounts cannot delete in tax operation, can be with then for the invoice for the mistake that keeps accounts, in practice
Keep accounts the invoice of a negative amount of money identical with the incorrect invoice amount of money again, to offset the influence of the incorrect invoice.In block chain
In, it is first determined wait rush red invoice for target invoice, then can create the invoice amount phase with the target invoice
Same negative amount of money invoice；Although negative amount of money invoice at this time creates but also needs to establish the negative amount of money invoice in block chain
With the mapping relations between the digital digest of the target invoice and/or the target invoice, can so be closed by mapping
System, determine incorrect invoice whether be completed rush it is red.
As shown in Fig. 2, block chain node receive for wait rush red invoice a rush red request after, can call pre-
If intelligent contract, inquire and whether there is this invoice a, i.e. target invoice described in this specification in block chain；And it is looking into
It askes there are after invoice a, is generated in block chain and rush red invoice a for invoice a, and established this on block chain and rush red hair
Mapping relations between ticket a and invoice a.It is red can to indicate that invoice a is rushed for the mapping relations of the foundation.It is described rush it is red
Invoice a is the negative amount of money identical with the invoice amount of invoice a.For example, the invoice amount of invoice a is 100 yuan, then red invoice a is rushed
Invoice amount be -100 yuan.
A kind of invoice based on block chain that this specification provides rushes red case, by by the digital digest of invoice and invoice
Cochain carries out depositing card；The feature and digital digest that can not be distorted due to the data presence stored in block chain have unique
Feature (i.e. the corresponding initial data of a digital digest)；Therefore, when discovery, certain invoice can be based on area when the error occurs
The digital digest of the invoice stored in block chain determines the corresponding target invoice on chain of the incorrect invoice (i.e. wait rush red invoice)；
And then it can create and the target invoice is associated rushes red invoice and close the corresponding of red invoice and the target invoice of rushing
It ties up in the block chain and is stored；In this way, the invoice amount of the incorrect invoice can be offset.
