Specific embodiment
Below in conjunction with attached drawing, an exemplary embodiment of the present invention will be described, including the various of the embodiment of the present invention
Details should think them only exemplary to help understanding.Therefore, those of ordinary skill in the art should recognize
It arrives, it can be with various changes and modifications are made to the embodiments described herein, without departing from scope and spirit of the present invention.Together
Sample, for clarity and conciseness, descriptions of well-known functions and structures are omitted from the following description.
Fig. 2 is a kind of schematic diagram of the key step of querying method based on block chain according to an embodiment of the present invention, such as
Shown in Fig. 2:
Step S201 indicates that block chain query node makes intelligent contract, wherein including inquiry word in the intelligence contract
Section；Intelligent contract is the common technology means in block chain technology, this term is at least for intelligent contract (Smart Contract)
Nineteen ninety-five can be traced back to, is put forward by the cross-cutting jurisprudent Ni Kesabo (Nick Szabo) of fecund.He
Be published in the theory for referring to intelligent contract in several articles of the website of oneself, be defined as follows: " an intelligent contract is a set of
The promise (promises) defined in digital form can execute the agreement of these promises including contract participant above.Intelligence
It can further include one or more of account information, signing messages, pricing information of the block chain query node in contract.Its
In, account information can indicate the account information of block chain query node (i.e. user), such as the deposit for including in account, machine of opening an account
Structure etc.；Signing messages is used to that the identity of the user of block chain query node to be identified and be verified；Pricing information indicates intelligence
The amount of money for the paid service arranged in energy contract.
Wherein inquiry field be used to indicate inquiry content, under normal circumstances, inquire field in further include looked into main body, such as
It inquires some and is looked into whether main body occurred certain behavior, if inquiry field is " whether Zhang San had overdue refund behavior ", that
Main body therein of being looked into is exactly " Zhang San ".For example, Fig. 3 is block chain schematic illustration according to an embodiment of the present invention；It is looked into
Main body is registrable in any one platform, and the platform being registered becomes user U.It is looked into main body registration and generates master data field
Afterwards, by user U by its information package cochain, the field that packing cochain needs are inquired can be user and carry out selection.
Step S202 indicates intelligence contract described in the block chain query node broadcasts；After broadcast, intelligent contract can be with
It is received by all nodes on entire block chain, the query context of query result is then expanded in point-to-area mode.
Step S203 indicates that the block chain destination node receives the intelligent contract, is looked into according to the intelligent contract generation
It askes as a result, wherein including the inquiry field and the corresponding result field of the inquiry field in the query result.Wherein
Corresponding result field, that is, block chain the destination node of the inquiry field (such as inquiry mechanism) according to inquiry Field Inquiry as a result,
If there is multiple queries field can then correspond to multiple result fields.For example, inquiry field is that " whether Zhang San had overdue refund to go
For ", then result field can be "Yes" or "No".It inquires the result that mechanism obtains inquiry and block chain is written, so that block chain
Query result can be generated in query result.It further, further include the label of the block chain destination node in the query result
Name information, the identity of the user to verify block chain destination node.
Step S204 indicates that the query result is sent to the block chain query node by the block chain destination node.
Since intelligent contract is broadcasted, so the block chain destination node received is more, then more it is possible to return and more looks into
Ask result.
Step S205 indicates that the block chain accounting nodes generate the block chain destination node and send out the query result
It send to the behavior record of the block chain query node, and generates intelligence contract described in the block chain query node broadcasts
Behavior record.According to the characteristic of block chain, the behavior occurred on block chain can be all recorded, the purpose of record be for the ease of
Tracking, can also trade according to these records.Block chain accounting nodes " are stayed away from work without leave " (Miner), block chain accounting nodes
The information recorded refers to the information of the distributed account book record of block chain.
The block chain query node receives the multiple queries result sent by the block chain destination node；The block
Chain accounting nodes generate the block chain query node and receive the multiple queries result sent by the block chain destination node
Behavior record.As shown in figure 4, user is in push if inquiry field is the inquiry about some by the bad credit for looking into main body
Addition inquiry field in inquiry request makes intelligent contract and broadcasts and (according to the characteristic of block chain, broadcasts intelligence according to inquiry request
Energy contract may need to pay a certain amount of reward GAS, be recorded by block chain accounting nodes).In multiple block chain targets
After node (mechanism) receives intelligent contract, inquired in respective blacklist library by the bad credit for looking into main body according to inquiry field
Record, is sent to block chain query node for the result inquired.
Since block chain has received multiple queries as a result, so to screen to query result, inquiry field pair is found out
The optimum field answered is adopted.The block chain query node is determined for the same inquiry field, including the inquiry
The quantity of the query result of the corresponding different result field of field；Such as in Fig. 4, in all query results, for same
One inquiry field, having includes result field " R1 " in 20 query results, and having includes result field in 10 query results
" R2 ", having includes result field " R3 " in 5 query results.So according to majority rule, the block chain query
Node determines that the inquiry field adopts result field according to the maximum value of the quantity.For example, utilizing result field " R2 "
" R3 " demonstrates the reliability of result field " R1 ", it should adopt result field " R1 ", adopt knot as the inquiry field
Fruit field.This step makes full use of multiple queries result mutually to be tested, and improves the reliability of query result.Further, right
, may not be identical in more complicated result field, it can be by text similarity than reciprocity technological means, to similar
It spends high result field to be clustered, result field is adopted in most can also be used as of sample in classification.
For the same inquiry field, the number of the query result including the corresponding different result field of the inquiry field
Measure it is equal in the case where, the block chain query node obtains the characteristic value of the query result；The block chain query node
Reject the query result of the characteristic value not in default range of characteristic values；For example, for example, in all query results
In, for inquiring field A, having includes result field "Yes" in 10 query results, and having includes result word in 10 query results
Section "No" can not adopt result field by majority rule determination at this time, so needing to obtain characteristic value to provide
More references.Wherein the corresponding characteristic value of the query result is for being described query result, and this feature value has
Comparability.For example, characteristic value can be time range, it include 10 query results of result field "Yes" in above-described embodiment
In, having 6 query times is two years ago, but the default range of characteristic values of query time is nearly 1 year, so this 6 query results
It does not refer in particular in range, should be removed default, then count the quantity including result field "Yes" again and just there was only 4, it can be true
Recognizing "No" is to adopt result field.For another example characteristic value can be to provide the registered capital of the mechanism of query result, it can be by feature
Value range is set as certain amount of money or more, so will be removed from the query result that registered capital is less than the mechanism of the amount of money.
Since characteristic value is the supplementary means for being verified to query result, and the selection of characteristic value needs obtaining query result
Determine that, so can further be obtained with paid mode as user, certainly, mechanism can also nothing according to verification result later
It repays and is provided for user.
Block chain accounting nodes record Token value (being also the tokens such as digital cash) is by the block chain query section
Point is transferred to the quantity of the block chain destination node；It include wherein the query result for adopting result field to sending
The quantity of Token value of block chain destination node transfer be the first quantity, do not include described not adopting result word to sending
The quantity of the Token value of the block chain destination node transfer of the query result of section is the second quantity；First number
Amount is greater than second quantity.According to the characteristic of block chain, the process of transaction is with the transfer of Token value, such as user needs
It pays to the mechanism for having sent query result.Since the query result that user side obtains has very much, but effective query result
(including the query result for adopting result field) may be only a part therein, so for justice and embodying query result
Value, difference inquiry fields payment amounts should be differentiated.User pays to each mechanism for providing query result
Take, but be not each mechanism fund obtained as many, due to the query result comprising adopting result field by with
Family is adopted, so in order to embody payment of these query results with higher value, to the mechanism for providing these query results
Answer more, and those do not include the verification process for adopting the query result of result field because taking part in query result, so answering yet
Acquisition small part reward.Agreement about payment can be arranged by intelligent contract.As shown in figure 4, due to result word
Section R1 has higher reliability, in order to embody result field R1 with higher real value, so to including result field
The supplier (i.e. mechanism) of R1 and its query result of corresponding inquiry field should give more Token values, i.e. user couple
The funds on account of these mechanisms payment should be more than other mechanisms.
Further, the block chain destination node can recorde the inquiry field and be looked into main body.In view of being looked into
Main body is applied inquiry because of certain reason, it is possible to which will be looked into main body records, and is later inquiry deposit
Information.Especially for main body is looked into there may be in the case where bad credit record, records and can prevent to main body is looked into
It further generates bad behavior of credit.
Further, the block chain accounting nodes are before or after generating behavior record, to the block chain
Destination node and/or the block chain query node obtain GAS value.It should be noted that according to the rule of block chain technology, area
Block chain accounting nodes will record various actions on block chain, especially generate the behavior of transaction, and for use block chain into
Capable various actions should also collect certain reward, so GAS value, similar to service charge, block chain query node (user) is wide
Broadcast information, block chain destination node (mechanism) sends query result and block chain query node (user) receives information and should
As block chain pays certain GAS value.It should be noted that the GAS value that block chain accounting nodes obtain, and record
Token is worth transfer to be that the form of account book in a distributed manner embodies, and true data transfer occurs without being bound to.
