Invention content
It is an object of the invention to overcome the technical problem present on, establish at a kind of data collaborative based on block chain
The method of reason：Block chain network is established, block chain network is added as node in each side of data collaborative processing, and in respective section
Intelligent contract is disposed in point, under the control of intelligent contract, the data needed for each node contribution collaboration processing are united by intelligent contract
One collects and handles, each nodes sharing of result data needed for contribution of processing.
To achieve the above object, the technical scheme is that in the following manner realizing：
(1) block chain network is established；
(2) block chain network, each inserting knot intelligence contract, in the control of intelligent contract is added in each node in block chain
Under, the data needed for each node contribution collaboration processing；
(3) intelligent contract carries out data collaborative processing to data, and the achievement of data collaborative processing is distributed to and provides number
According to each nodes sharing.
Further, each node status in the step (1) in block chain is identical, without Centroid, any node
Data collaborative processing request can all be initiated.
Further, the whole process that data collaborative is handled in the step (3) is executed under the control of intelligent contract
, the intelligence contract comprises the following steps：
Step S1 is searched after each node receives the request of data collaborative processing in block chain network needed for collaboration processing
Data simultaneously submit to intelligent contract use, and intelligent contract records whether each node submits data needed for collaboration processing；
Step S2, intelligent contract are collected required data from each node, are added according to pre-defined data collaborative process flow
Work generates result；
The case where step S3, each node that intelligent contract is recorded according to step S1 submits data needed for collaboration processing, to each
The result generated after node distribution data collaborative processing.
Further, in the step S1, when some node does not find the required data of collaboration processing, then will not
Data are submitted to intelligent contract.
Further, in step S3, intelligent contract only submitted the node of the data needed for collaboration processing into step S1
Distribute the result generated.
Further, node can only obtain data collaborative processing as a result, will not obtain the submission of other nodes for counting
According to the data of collaboration processing.
The present invention solves the technical issues of traditional data collaboration processing must rely on third-party platform processing, passes through intelligence
Contract is unified to the data of each node to be collected and handles, and is not necessarily to third-party platform, is improved reliability, the peace of data collaborative processing

Description of the drawings
Fig. 1：The structural schematic diagram of the block chain node of the present invention.
Fig. 2：Bank node of embodiment of the present invention A initiates the credit evaluation to enterprise E and asks flow chart.
Specific implementation mode
The following describes the present invention in detail with reference to the accompanying drawings and embodiments.
As shown in Figure 1, the scene that the present embodiment is chosen is 4 business bank (A, B, C, D) composition block chain networks, 4
Bank node can access the database being positioned in bank's Intranet by interface, and 4 banks contribute the data of itself respectively, lead to
After the intelligent contract disposed in advance, the data of 4 business banks are concentrated, by advance trained model, enterprise are carried out comprehensive
The credit evaluation of conjunction.
Present embodiment assumes that certain enterprise E, handled business, in bank in bank node A, bank node B and bank node C
Node D did not handle business, so, there are enterprise E's in the database of bank node A, bank node B and bank node C
The business datum of enterprise E is not present in the database of bank node D in business datum.
It is asked present embodiment assumes that bank node A initiates the credit evaluation to enterprise E, as shown in Fig. 2, whole process is such as
