The cryptographic Hash (hash) of a block is contained, is initially connected to current block, shape from original block (genesis block)
Blocking chain.Block chain is also the distributed data base system participated in by node, is substantially the database account an of decentralization
This, records all transaction records, with electric business platform, payment platform using the transaction system that logistics platform forms as block link network
For network, each person of participating in business is the node of block network, and each node has a complete public account book backup,
All Transaction Informations since birth of trading are recite above.Any one node initiates trading activity and requires to believe correlation
Breath is transmitted to each of block network node, thus, the account book on all nodes can verify this transaction behavior simultaneously
It is accurate to update.In addition, account book is blockette storage, with the increase of transaction, new data block can be attached to already present chain
On, form chain structure.
Each node on block chain can store the intelligent contract on operation block chain, an intelligent contract be it is a set of with
The promise (promises) that digital form defines can execute the agreement of these promises including contract participant above.When one
When a transaction request for carrying parameter transaction is passed on the node of block chain, it is corresponding that this parameter transaction can be recorded to the node
Transaction journal on and be transmitted to intelligent contract corresponding with the parameter transaction simultaneously and go to run, and by the corresponding intelligence of the parameter transaction
Code on energy contract is updated the data of intelligent contract.
The intelligent contract is simultaneously deployed in block chain network, the intelligence contract rule by building transaction verification intelligence contract
The clause of transaction verification contract is determined, the intelligence contract includes the computer generated according to the clause of the transaction verification contract
Execute code.
It should be noted that in this step, transaction verification contract can be with specifically: when detecting working as on electric business platform
When preceding transaction is " trading successfully " state, the logistics record of logistics platform, payment are flat on traversal block chain network inquiry block chain
With the presence or absence of the logistics record and payment record with same order number of currently trading on electric business platform in the payment record of platform, if
Logistics platform and/or payment platform be not present with identical O/No. of currently trading on electric business platform, then current transaction is judged to
It is set to abnormal exchanges；Otherwise, the record information for comparing lower three platforms of the same O/No., judges the record of three platforms
Information whether in correspondence with each other, if in correspondence with each other, current transaction is determined as arm's length dealing, if can not correspond to, be determined as it is non-just
Often transaction.The intelligent contract disposed in step S1 need to can just be recorded to block chain after block chain network confirms and obtains common recognition
In network, and the intelligence contract is open and clear to distort.
S2: electric business platform, payment platform and logistics platform are respectively by corresponding transaction record, payment record and logistics
For record as dynamic transaction data publication to block chain, block chain is synchronized to each node, and the dynamic transaction data carrying is ordered
Parameter transaction including single identification information.
Three platforms will store sequentially in time with related each dynamic of currently trading to area on respective platform respectively
In block chain network, i.e. this is dynamically used as transaction data to store to block chain network by one dynamic of every generation, so that current hand over
A chain structure is constituted with time sequencing after easy each block (i.e. transaction dynamic data) capping timestamp.Meanwhile according to
The principle of block chain, three platforms are during being uploaded to block chain for dynamic data, it is necessary to using the private key of itself to dynamic
State data are digitally signed, therefore can guarantee the authenticity of data source header.
The step ensure that the succession, reliability and data of dynamic data are open and clear, can not distort, convenient in intelligence
When energy contract executes, data, comparison data are inquired.
S3: the intelligent contract of node corresponds to the dynamic transaction data for meeting starting transaction authenticity verification condition
Order note identification information, corresponding transaction record is found out by order note identification information, payment record and logistics record, is handed over
Easy authenticity verification provides transaction authenticity result according to verification result.
Friendship according to the status condition set in the transaction verification agreement terms to the electric business platform in block chain network
Easily the payment record of record, the logistics record of logistics platform and payment platform carries out real-time tracking, meets the status bar of setting
When part, the computer executable code in the intelligent contract is executed automatically.
For example, the intelligent contract of node to meet starting transaction authenticity verification condition dynamic transaction data be by with
Lower method judges:
Comprising transaction, whether successful stateful transaction is as parameter transaction in the transaction record of electric business platform；
The intelligent contract of node detects that the parameter transaction in dynamic transaction data includes that electric business platform is currently traded " to hand over
The stateful transaction of easily success ", then it is assumed that meet starting transaction authenticity verification condition.
The present invention provides the first implementation are as follows:
Electric business platform, payment platform and logistics platform store electric business platform dynamic data base, payment platform dynamic respectively
Database and logistics platform dynamic data base；
Those database informations are distributed to block chain, and block chain is synchronized to each node；
After node receives dynamic transaction data, dynamic transaction data are first updated to corresponding electric business platform dynamic number
According to library, payment platform dynamic data base and logistics platform dynamic data base, and it is synchronized to each node of block chain；
After the intelligent contract of node obtains the order note identification information of dynamic transaction data, by traversing electric business platform dynamic number
It finds according to library, payment platform dynamic data base and logistics platform dynamic data base with the corresponding record of same order identification information
Information；
Intelligent contract is by judging whether the parameter in the record information meets preset transaction authenticity verification
Contract carries out transaction authenticity verification.
Safeguard that electric business platform dynamic data base, payment platform dynamic data base and logistics are flat in block chain network in advance
Platform dynamic data base obtains corresponding order when receiving the dynamic transaction data for meeting starting transaction authenticity verification condition
Single identification information, by accessing electric business platform dynamic data base, payment platform dynamic data base and logistics platform dynamic number respectively
It is traversed according to library with order note identification, trade very according to preset condition after directly would know that corresponding record information
Reality verifying, it is realisation strong, in traversal electric business platform dynamic data base, payment platform dynamic data base and logistics platform dynamic number
According to library disposed of in its entirety speed can be improved with parallel processing.
The present invention provides second of implementation are as follows:
Setting transaction dynamical system, save current dynamic transaction record, payment record and logistics be recorded in it is current
Dynamic transaction data；
After node receives dynamic transaction data, dynamic transaction data are first updated to transaction dynamical system, and establish
Association between the current dynamic transaction data of same order mark, and updated transaction dynamical system is synchronized to block chain
Each node on；
The intelligent contract of node obtains corresponding order to the dynamic transaction data for meeting starting transaction authenticity verification condition
After single identification information, direct access transaction dynamical system, by its degree of association obtain corresponding transaction record, payment record and
Logistics record.
I.e. the present invention setting transaction dynamical system, and in block chain network the real-time servicing transaction dynamical system dynamic
Data；After node receives dynamic transaction data, dynamic transaction data are first updated to transaction dynamical system, and are established identical
Association between the current dynamic transaction data of order note identification, when the intelligent contract of node is to the qualified dynamic transaction of verifying
Data, direct access transaction dynamical system obtain corresponding transaction record, payment record and logistics by its degree of association and remember
Record.Very big in view of transaction dynamical system data volume, we pre-establish relevance, when needing authenticity verification of trading
When, corresponding data are directly found by its relevance, improve access speed, while greatly improving transaction authenticity verification
Efficiency.
It should be noted that the transaction record of the electric business platform include O/No., seller electric business platform account, sell
The delivery address that the title of family, seller register；
The consignee's name and shipping address and connection that the electric business platform account of buyer, the title of buyer, buyer fill in
Phone, order creation time, product name and quantity and corresponding turnover；
The logistics platform logistics record include O/No., delivery availability, consignor's title and delivery address and
Telephone number, consignee's name and shipping address and telephone number, product name；
The payment record of the payment platform includes O/No., the title of requestee and payment platform account, payee
Title and payment platform account, product name, time of payment and payment amount.
The step S3 specifically: in the transaction record, logistics record and payment record on monitoring electric business platform whether
There is the same O/No., when the record of the same O/No. occur in three platforms, obtains respectively same on three platforms
Record information under one O/No., and judge whether it meets the following conditions:
The order creation time < time of payment < delivery availability；
Whether product name is identical；
Payment amount on turnover=payment platform on electric business platform；
Payee on title==payment platform of consignor on the title of seller==logistics platform on electric business platform
Title；
The delivery address on delivery address==logistics platform that seller registers on electric business platform；
On electric business platform on the title of buyer==payment platform requestee title；
Consignee's title on consignee's title that buyer fills on electric business platform==logistics platform；
The telephone number of consignee on consignee's telephone number that buyer fills on electric business platform==logistics platform,
When the above comparison passes through, corresponding trade of the O/No. is determined as arm's length dealing, otherwise, is judged as
Abnormal transaction.
Above intelligent contract rule is merely illustrative of, this example can be combined using a variety of Different Rules, can also be with
Different rules is changed, above-mentioned intelligence contract rule is only used for illustrating.
S4: transaction authenticity result is synchronized to each node by block chain.
Computer executable code executes the result generated and stores as transaction data into block chain network, the block chain
Network includes the multiple nodes being made of electric business platform, payment platform and logistics platform.
The step S4 specifically: the verification result currently traded is used as transaction data to confirm through block chain network and obtains
It is recorded after common recognition in block chain network, is consulted for associated mechanisms.
In addition, preferably, the data for being verified as abnormal exchanges are sent to corresponding regulatory agency, so as to empty to forging
The case where vacation transaction, is handled, and further standard market keeps the good order in market.
Comprising transaction, whether successful stateful transaction is as parameter transaction in the transaction record of electric business platform；The intelligence of node
It is the stateful transaction of " trading successfully " that contract, which detects that the parameter transaction in dynamic transaction data is currently traded comprising electric business platform,
Then think to meet starting transaction authenticity verification condition.In view of the safety of the transaction status information of " trading successfully ", this Shen
It asks someone additional encryption code key, payment platform and logistics platform conduct can also be arranged as publisher node for electric business platform
Corresponding deciphering parameter is arranged in the recipient of authorization, and this rights management further promotes its safety.
The embodiment of the invention discloses a kind of transaction verification system based on block chain and intelligent contract, as shown in Fig. 2, packet

It should be noted that the intelligence contract execution module can be certainly according to the regulation of the clause of transaction verification contract
Master is monitored the state of every transaction on electric business platform, and under appointment state, i.e., current transaction becomes to trade successfully shape
When state, the record of logistics platform and payment platform in block chain network is inquired, is compiled according to the order currently traded
Whether logistics platform in number inquiry block chain network occurs the record of same order number in payment platform, if logistics platform and/
Or payment platform be not present with identical O/No. of currently trading on electric business platform, then current transaction is judged as improper friendship
Easily；Otherwise, the record information for comparing lower three platforms of the same O/No. judges whether the record information of three platforms is mutual
It is corresponding, if in correspondence with each other, current transaction is determined as arm's length dealing, if can not correspond to, it is determined as abnormal exchanges.
More specifically, in the embodiment of the present invention, intelligent contract execution module includes monitoring unit, data query unit, ratio
To unit, prewarning unit,
The monitoring unit, for monitoring the transaction record state of the electric business platform, the state packet of the transaction record
It includes: waiting buyer's payment；Buyer's received payment waits seller's delivery；Seller is shipped, and buyer's confirmation is waited to receive；It trades successfully；
Transaction is closed.
It is general as follows by the process of the purchase transaction of electric business platform: buyer after electric business platform finds corresponding commodity,
It is placed an order (i.e. creation transaction) by electric business platform, in the process, buyer needs to fill in consignee's information, including consignee's surname
Name, address and telephone number, after submitting order, stateful transaction becomes " waiting buyer's payment "；Electric business platform calls later
Payment platform, buyer by payment platform to seller pay payment for goods, after paying successfully, stateful transaction become " buyer's received payment, etc.
It delivers to seller "；After seller is connected to the notice that electric business platform has been paid the bill about buyer, filled in by logistics platform to buyer
Addressee's delivery, at this point, stateful transaction becomes " seller is shipped, and buyer's confirmation is waited to receive "；When buyer confirmation receive or
It reaches after certain timi-lemited system automatically confirms that and receive, stateful transaction becomes " trading successfully "；If buyer is providing after creating order
It arrearage or there is a situation where reimbursement or returns goods in time, stateful transaction becomes " transaction close ".
When monitoring unit monitors that the stateful transaction currently traded on electric business platform becomes " trading successfully ", log-on data
Query unit.
The data query unit, for when the state of the transaction on electric business platform be trade successfully when, according to trade at
The O/No. inquiry logistics platform and payment platform of function whether there is the record of same order number.
It should be noted that transaction verification system of the present invention is to be directed to need the transaction for the physical commodity delivered true
Reality verifying.Therefore, when the stateful transaction currently traded on electric business platform becomes " trading successfully ", if it is arm's length dealing,
It means that logistics platform and payment platform have the logistics record and payment record of same O/No. therefore to verify
The authenticity of transaction first has to verifying electric business platform, whether three platforms of logistics platform and payment platform occur similarly ordering
The record singly numbered.
The comparing unit inquires electric business platform, logistics platform, the same O/No. of payment platform appearance for working as
Record when, the record information of three platforms under the same O/No. is compared, judges that the information of three platforms is
It is no in correspondence with each other.
Described in the embodiment of the present invention in correspondence with each other be specially following information in correspondence with each other:
The order creation time < time of payment < delivery availability；
Whether product name is identical；
Payment amount on turnover=payment platform on electric business platform；
Payee on title==payment platform of consignor on the title of seller==logistics platform on electric business platform
Title；
The delivery address on delivery address==logistics platform that seller registers on electric business platform；
On electric business platform on the title of buyer==payment platform requestee title；
Consignee's title on consignee's title that buyer fills on electric business platform==logistics platform；
The telephone number of consignee on consignee's telephone number that buyer fills on electric business platform==logistics platform.
The prewarning unit, for being compiled when inquiry the same order occurs less than electric business platform, logistics platform, payment platform
Number record or the information of three platforms when can not be in correspondence with each other, to corresponding mechanism alert.
Being stored after digital signature by platform to block chain network in the record information of three platforms can guarantee to believe
Under the premise of ceasing source authenticity, if logistics platform and payment platform are not present and the O/No. traded on electric business platform
Record, then the current transaction of explanation is after the creation transaction of electric business platform, and arrearage is also non-shipment, and stateful transaction is " transaction
Success ", above situation is confirmed to be wash sale in embodiments of the present invention.
In addition, according to the transaction flow of electric business shopping it is found that electric business platform, logistics platform, the information on payment platform are answered
This be it is interrelated in correspondence with each other, if comparing unit can not be interrelated mutually opposite after comparing the information of three platforms
