Data processing generally refers to the process handled according to certain processing rule target data.For example, data
Analysis, is namely based on default rule, analyzes target data, to obtain analysis result.
Traditional data processing is mostly privately owned；I.e. enterprise carries out data processing, place using the data processing system of oneself
It is also all privately owned for managing result.Since data processing system is the privately owned customization of user, final data processed result can only
Private, it is difficult to open shared.Such as internet financing corporation, respectively possess oneself credit scoring system, user's portrait.
And privately owned data processing, treatment process are that enterprises are realized；Can't external disclosure, also without outer
Portion's supervision；Lack open and oversight mechanism, exists to the mistrustful problem of enterprise.
This specification embodiment provides a kind of data processing scheme based on block chain, by advance in block chain
The corresponding intelligent contract of each dimension needed for publication carries out multi-dimensional data processing；Business side initiate for target data into
After the transaction of row various dimensions processing, the data process method stated in the corresponding intelligent contract of each dimension is called, to each dimension
The target data and historical data of degree are handled.Wherein, this specification additionally provides a kind of association structure of cochain transaction, leads to
Digital digest of the hash value being calculated for father's transaction content as son transaction is crossed, so that the transaction in each dimension be connected
Get up, and the digital digest of the last time transaction is recorded in the intelligent contract of corresponding dimension；To target data into
When row processing, the digital digest that can be traded based on the father recorded in the intelligent contract of each dimension obtains the historical data of each dimension.
On the one hand, the processing of the multi-dimensional data based on block chain, and can not distort due to block chain may be implemented in this specification, from
And it ensure that the validity of data processing；On the other hand, open and clear due to block chain, data processed result the whole network can be shared
Improve data circulation efficiency.
It is noted that a kind of association structure for cochain transaction that above-mentioned this specification provides, can refer to block chain
In deposit incidence relation in the transaction of card between the historical data of identical dimensional.In this way, realizing between the data of various dimensions
Association and can not be tampered.
Please refer to the association structure schematic diagram between the different blocks in block chain shown in FIG. 1 with dimension historical data.Fig. 1
In, it is all to be generated according to block generating mode in traditional block chain between block 0, block 1, block ..., block N-1 and block N
's.The block head of block is the hash value of the block body of a upper block.For example, the block head of block 1 is the block according to block 0
The hash value arrived that body hash is calculated；That is in Fig. 1 shown in solid arrow.
Historical trading is generally recorded in the block body of block.One transaction may include the data of multiple dimensions.It is false
If data Tx 1 belongs to the first dimension in block 0, data Tx 2 belongs to the second dimension, and data Tx N belongs to third dimension.So
In Fig. 1, the data for belonging to the first dimension include Tx 1 in block 0, Tx 1 in the Tx 1 in block 1, block N-1 and
Tx 2 in block N, arrow 1 is associated with by a dotted line between the data of the first dimension；
Similar, the data for belonging to the second dimension include Tx 2 in block 0, in the Tx N in block 1, block N-1
Tx 2 and block N in Tx 1, arrow 2 is associated with by a dotted line between the data of the second dimension；
The data for belonging to third dimension include Tx N in block 0, the Tx N in the Tx 2 in block 1, block N-1 with
And the Tx N in block N, arrow 3 is associated with by a dotted line between the data of third dimension.
It should be noted that Fig. 1 understands that a data have only corresponded to a dimension for convenience, in practical applications one
A data can be to should belong to multiple dimensions.
Specifically, practical indicate is digital digest to dotted arrow.For example, in the first dimension, the Tx 1 and block of block 0
12 incidence relation of Tx is practical are as follows:
The digital digest of the Tx 2 of block 1 includes the hash value being calculated for the content hash of the Tx 1 of block 0；0
Indicate that block, Tx 1 indicate data.The digital digest of the Tx 2 of block N is to calculate for the content hash of the Tx 1 of block N-1
Obtained hash value.
Similar, in the second dimension, the digital digest of the Tx N of block 1 is to count for the content hash of the Tx 2 of block 0
Obtained hash value；Etc. repeat no more.
The digital digest traded by the hash value being calculated for father's transaction content as son, thus by each dimension
Transaction be together in series, and by the last time transaction digital digest be recorded in the intelligent contract of corresponding dimension.
By taking the first dimension as an example, when there is no historical trading, the number of father's transaction in the corresponding intelligent contract of the first dimension
Abstract is empty (null)；When there is first block 0, the digital digest of the father's transaction recorded in intelligent contract is updated to hash
(0, Tx 1) wherein, 0 can indicate that father trades (block), and Tx 1 indicates data；When there is second block 1, update again
For hash (1, Tx 1)；When there is N-1 block, it is updated to hash (N-1, Tx 1)；When there is n-th block, more
Newly it is hash (N, Tx 2).
This description presents a kind of flow charts of data processing method based on block chain for introduction as shown in Figure 2 below.
The described method includes:
Step 110: receiving the transaction that various dimensions processing is carried out for target data that business side initiates；
Step 120: responding the transaction, inquire the corresponding intelligent contract of each dimension；
Step 130: the data process method stated in the corresponding intelligent contract of each dimension inquired described in calling；Its
In, the data process method includes: the history number of current dimension in the target data and historical trading for obtain current dimension
According to, and the target data and historical data of the current dimension are handled.
The block chain described in this specification can specifically include privately owned chain, shared chain and alliance's chain etc., in this theory
Without being particularly limited in bright book.
For example, in one scenario, above-mentioned block chain specifically can be by each enterprise for carrying out data processing as connection
One alliance's chain of alliance's member composition；The operator of alliance's chain can rely on alliance's chain, to dispose corresponding business；And
Enterprise as allied member described above all can serve as a service node of above-mentioned business.Each service node can
With by produced by itself or receive and business datum issued in alliance's chain in the form traded, and in the transaction
After common recognition processing by the common recognition node in alliance's chain, the distributed data base in alliance's chain is stored, in completion
" cochain " for stating Transaction Information deposits card.
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, data processing business etc.) of value Transfer, and in this kind of alliance's chain
In, transaction can be the service message or service request with business intention that user issues in alliance's chain.
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.
The corresponding intelligent contract of each dimension in this specification in block chain can be by the creation of any alliance side.Tool
Body, in one embodiment, the method also includes:
Receive the corresponding intelligent contract of any dimension of any alliance side's creation in alliance's chain；
Call the ballot logic stated in the intelligent contract being published on alliance's chain；Wherein, the ballot logic are as follows:
A ballot event is written in transaction log, after the alliance side of alliance's chain listens to the ballot event,
Vote trading is submitted to the intelligent contract；The intelligence contract carries out vote trading to summarize arrangement, obtains any dimension
Spend the auditing result of corresponding intelligent contract.
Some alliance side's (also referred to as federation node) in any one alliance's chain can initiate creation multidimensional to alliance's chain
Spend the transaction of the intelligent contract of data processing.It audits, and returns to intelligent contract of each alliance side in alliance's chain to creation
Return voting results；If the voting results of statistics meet preset condition, the intelligent contract created comes into force.
Below in conjunction with the flow diagram of the intelligent contract of Fig. 3 introduction creation multi-dimensional data processing.

Whether come into force.
3, the alliance side A in alliance's chain initiates the transaction of the intelligent contract of creation multi-dimensional data processing.
Alliance side can submit multiple intelligent contracts, and each intelligence contract represents a dimension of data processing.
3.1, after intelligent contract creates successfully, creation result and contract address are returned to alliance side.
If intelligent contract cochain, each intelligence contract can be assigned a unique contract address, according to conjunction
About address can be routed to the intelligent contract of storage.
4, alliance side A initiates the registration request of the intelligent contract of creation；
4.1, master control intelligence contract registers intelligent contract, and records contract address.
Master control intelligence contract records the contract address of intelligent contract, is routed so as to subsequent.
4.2, registering result is returned to alliance side A.
5, alliance's chain is broadcasted to the whole network and is notified, each alliance side is notified to carry out the ballot of intelligent contract.
6, each alliance side audits intelligent contract, and submits voting results to ballot contract.
7, the ballot contract of alliance's chain counts voting results, if voting results reach preset condition, notice connection
A intelligence contract in alliance side comes into force.
Wherein, the preset condition may include that the quantity that passes through of ballot audit reaches threshold value, then it is assumed that pass through.Here
Threshold value can be to be adjusted flexibly according to demand, if audit is intended to strictly, threshold value can be arranged to alliance's number formulary amount
90%；If audit is intended to loosely, threshold value can be set to the 50% of alliance's number formulary amount.
In this way, the intelligent contract for multi-dimensional data processing comes into force, multi-dimensional data processing can be provided for business side
Service.
In one embodiment, the response transaction is inquired the corresponding intelligent contract of each dimension, is specifically included:
The transaction is responded, calling is published on the routing logic stated in the master control intelligence contract of the block chain, inquires
The corresponding intelligent contract of the dimensional parameter carried in the transaction.
In practical applications, if business side needs invocation target intelligence contract needs to write Intelligent target conjunction exactly in transaction
Contract address about；However in practical applications, since intelligent contract quantity is more, especially multidimensional shown in this specification
The intelligent contract of data processing is spent, a dimension has just corresponded to an intelligent contract, and many intelligent contracts are all by alliance
It just creates, the contract address of each intelligent contract is remembered if necessary by business side, then higher cost.For this purpose, this specification
Provide one for routing master control intelligence contract, business side, which only needs to write the dimension that needs to be implemented exactly in submitting transaction, to be joined
Number, comprehensive intelligent contract can be routed to the intelligent contract of corresponding dimension automatically according to dimensional parameter.
Further, it can also judge whether the intelligent contract inquired comes into force, each dimension pair inquired described in calling
The data process method stated in the intelligent contract to come into force answered.
As shown in figure 3, also needing alliance side to carry out audit ballot after intelligent contract creation, only the case where voting through
Under, intelligent contract can just come into force.Therefore, when carrying out data processing, the intelligent contract to come into force may only also be called.
