In common recognition mechanism, determine that current block generates node, it is suitable come the sequence serviced according to order to generate node by current block
Sequence successively receives and processes each cochain transactions requests.
Cochain transactions requests are sent to other sections of block chain network according to the endorsement strategy in intelligent contract by S302
Point, so that other nodes feed back endorsement result after carrying out endorsement operation to the blacklist data in cochain transactions requests；Endorsement behaviour
The process of work is that other nodes verify blacklist data, on the blacklist in data add check results and itself
Node identification, and the process that the blacklist data for being added to check results and node identification is encrypted.
Wherein, the intelligent contract of block chain can be a set of promise defined in digital form, which contains block
The rights and duties that the corresponding financing corporation side of each node of chain arranges jointly generate node by the block in block chain to execute.
It may include endorsement strategy in intelligent contract in the present embodiment, endorsement strategy, which can be used to refer to lead, executes endorsement operation
Node, how decision transaction whether correct condition, for example, when execute endorsement operation node receive cochain transactions requests
Blacklist data when, task relevant to verifying system (chaincode) of blacklist data can be called as blacklist
A part of data check process determines the validity of the blacklist data.
Illustratively, current block generates node in the cochain thing comprising blacklist data for receiving client upload
After business request, the cochain transactions requests comprising blacklist data are sent to area first according to the endorsement strategy in intelligent contract
Other nodes on block chain can carry out the endorsement node of endorsement operation, wherein can be by block chain network in block chain
In all clients node all as endorsement node, be also possible to using the portions of client end node in block chain network as
Endorsement node, in this regard, the embodiment of the present invention is without limiting.Other nodes on block chain are receiving current block generation
After the cochain transactions requests comprising blacklist data that node is sent, according to the endorsement plan in the intelligent contract of respective block chain
Slightly, endorsement operation is carried out to the blacklist data in cochain transactions requests.
Optionally, specifically endorsement operating process may include: to be called and verified with blacklist data based on endorsement strategy
The relevant task program code of system carries out validity check to the blacklist data in cochain transactions requests, if verifying successfully,
Then addition verifies the node identification of success message and the node itself in the blacklist data, and will attach and verify successfully
The blacklist data of message and own node mark is encrypted, and endorsement result is obtained；If authentication failed, endorsement behaviour is executed
The node of work can be the node identification of addition verification failed message and the node itself in blacklist data, and will add
Verification failed message and the blacklist data of own node mark are encrypted, and endorsement result is obtained.Optionally, of the invention
In embodiment, can be private key using the node to attached the blacklist datas of check results and own node mark into
Row encryption, using encrypted data as endorsement result；It is also possible to using (such as Hash encryption calculation of preset Encryption Algorithm
Method) blacklist data for having attached check results and own node mark is encrypted, using encrypted data as endorsement
As a result；The blacklist data for having attached check results and own node mark can also be encrypted using other modes, it is right
This present embodiment is without limiting.
It, will after blacklist data of each node of execution endorsement operation on to chain in request of data carries out endorsement operation
Its endorsement result for endorsing operation feeds back to current block and generates node.Optionally, if it is also endorsement that current block, which generates node,
Node, then current block, which generates node, has endorsement function cochain transactions requests are sent to other of block chain network
Node carry out endorsement operation while, the current block generate node also to the blacklist data in the cochain transactions requests into
Row endorsement operation regard the endorsement result that the endorsement result of itself and other nodes return as final endorsement result together.
Illustratively, as shown in figure 4, to handle the first cochain thing that company A client node 403 is sent to block chain
For business request, if it is B corporate client end node 413 that current block, which generates node, and endorsement can be executed in block chain network
The node of operation includes: company A client node 403, B corporate client end node 413 and C corporate client end node 423, then B
Corporate client's end node 413 is sent to company A client according to the endorsement strategy in intelligent contract, by cochain transactions requests
Node 403 and C corporate client end node 423；Company A client node 403, B corporate client end node 413 and C corporate client
For end node 423 respectively according to the endorsement strategy in intelligent contract, it is accurate to carry out to the blacklist data in cochain transactions requests
Property verification, check results and itself node identification are added in blacklist data, and check results and node will be added to
The blacklist data of mark is used as endorsement result to feed back to B corporate client end node 413 after being encrypted.
S303 receives the endorsement of other node feeding backs as a result, verifying to endorsement result.
Illustratively, block generates node after receiving the endorsement result of other node feeding backs, carries out to endorsement result
When verifying, it can be in verifying endorsement result, each node for executing endorsement operation is added to the check results in blacklist data
It whether is to verify success message, and whether the node identification that verifying is added in blacklist data is correct.Optionally, due to
Execute endorsement operation node be multiple nodes, then can be when meet in multiple nodes preset ratio (such as 2/3rds with
On) node addition check results all be verification success message, and its addition node identification it is all correct, then explanation to back
The success of book result verification, that is, illustrate that the blacklist data in cochain transactions requests is effective, can be written into block chain.
Illustratively, as shown in figure 4, B corporate client end node 413 according to the company A client node 403 received,
C corporate client end node 423 and the endorsement itself determined are as a result, verify all endorsement results, if three endorsements
As a result all proved after the endorsement result verification for having 2/3rds in the blacklist in cochain transactions requests effectively (have three/
Check results are all verification success message to two endorsement result after decryption, and the node identification added is all correct), it is determined that
This endorsement result verification is correct, then illustrates that the blacklist data of A financing corporation storage to be uploaded is effective, i.e., to endorsement result
It is proved to be successful.
Optionally, what the process verified to endorsement result used when can be and generating according to each node and endorse result
Verification operation is decrypted to each endorsement result in Encryption Algorithm, for example, if endorsement is the result is that use the private key of other each nodes
What encryption generated, then verifying is decrypted to each endorsement result using the public key of other each nodes；If reaching the back of preset ratio
The success of book result decryption verification, then the endorsement result verification success.Specifically, if endorsement is the result is that execute endorsement operation
After node is added to the node identification of itself in blacklist data, encryption generation is carried out using the private key of the node, then at this time
Endorsement result is decrypted using the public key of the corresponding node of endorsement result, in the blacklist data after checking decryption
Whether verification success message is had, and whether the node identification of addition is correct, if so, illustrate endorsement result verification success,
Illustrate that the endorsement result verification fails if.Above-mentioned verification operation is carried out to each endorsement result, is finally checked all
In result of endorsing, always the endorse ratio of result of the endorsement result Zhan being proved to be successful if reaching preset ratio illustrates that endorsement is tied
Fruit is proved to be successful.It should be noted that if endorsement is the result is that other each nodes are using preset Encryption Algorithm, (such as Hash is encrypted
Algorithm) generate, then it can be using preset Encryption Algorithm (such as Hash Encryption Algorithm), endorsement result be decrypted and is tested
Card, specific verification process is consistent with being verified public key and carrying out the secret process of verifying to endorsement result, to this without going to live in the household of one's in-laws on getting married
It states.
S304, if be proved to be successful, using blacklist data as in Transaction Information write-in block chain.
Illustratively, if current block generates node to endorsement result verification success, illustrate in cochain transactions requests
Blacklist data it is effective, therefore, can will the blacklist data for including in cochain transactions requests be written block chain in.It is optional
, in order to guarantee the validity of blacklist data, can be while block chain is written in blacklist data, it will be black to this
Successfully also block is written with the blacklist data in the node identification of each node and verification success message together for list data endorsement
In.
Optionally, current block generate node using blacklist data as Transaction Information write-in block chain after, can be to
Other nodes transmission in block chain network is proved to be successful message, so that other nodes are by the blacklist in cochain transactions requests
Data are written in the block chain of own node.Optionally, in order to guarantee the validity of blacklist data, current block generates section
Point is also possible to be written into the block hair of blacklist data and the corresponding node identification of blacklist data and verification success message
Each node into block chain network is sent, so that the block received is linked in the block chain of itself by each node.
Optionally, if authentication failed, illustrate that the blacklist data to be uploaded for including in cochain transactions requests is inaccurate
Really, i.e., the blacklist data that client node uploads is actually white list data, is client node other public affairs in order to prevent
The data taking charge of extension white list client and maliciously uploading.Therefore, in order to guarantee the standard of the blacklist data stored in block chain
True property, does not execute the operation for the blacklist data write-in block chain network to be uploaded that will include in cochain transactions requests, and wants
To initiate the cochain transactions requests client node punished accordingly, such as can be deduction initiation the cochain affairs ask
The client node account asked motivates logical card accordingly；It is also possible to cancel the client node and is sent in block chain network
The permission etc. of blacklist data inquiry request in cochain transactions requests and chain.To this embodiment of the present invention without limiting.
S305 updates the logical card of current excitations of client node account according to the incentives strategy in intelligent contract.
Wherein, not only include endorsement strategy in the intelligent contract of block chain, further include incentives strategy.Incentives strategy can be with
It is the rule being arranged to motivate each financing corporation for being added to block chain network to store accurate blacklist data into block chain
Then, for example, may include: that each financing corporation uploads a blacklist client, how many logical cards of excitation are rewarded；Each finance is public
It takes charge of the blacklist client uploaded and is obtained primary, the logical card of how many excitations of reward by other companies；Each financing corporation uses primary
The blacklist client that other financing corporations upload deducts logical card of how many excitations etc..It optionally, can for different rewards and punishments scenes
Think that certain proportionate relationship is arranged in reward or the number of the logical card of the excitation of deduction, which can be according to the actual situation
It is adjusted under the supervision and approval of each financing corporation.The logical card of excitation can be effective for motivating each financing corporation to upload
Blacklist data and integral, the bonus etc. being arranged.
Illustratively, since the client node that the embodiment of the present invention is financing corporation uploads storage to block chain network
The process of blacklist data, it is possible to which each company according to specified in incentives strategy uploads a blacklist client, reward
The logical card of excitation number, to the logical card of excitation for the financing corporation's reward corresponding number for uploading the blacklist data, i.e., at this
In the client account of financing corporation, on the basis of original excitation logical card, it is corresponding sharp to increase this upload blacklist data
Encourage logical card number.For example, if providing in incentives strategy, company one blacklist client of every upload increases by 0.1 integral, if A is public
Integral of 403 account of client node of department before uploading this blacklist data is 10 integrals, this blacklist number uploaded
There are 10 blacklist clients in, then can be 1 integral of increase, i.e., the integral of 403 account of company A client node is at this time
11 integrals.
Blacklist sharing method provided in this embodiment based on block chain, current block generate node and are receiving client
After cochain transactions requests of the end node according to the blacklist data generation wait store, cochain transactions requests are sent to other sections
Point carries out endorsement operation, and endorsement operating result is fed back to current block generation node and verified by other nodes, if currently
Block generates node verification success, then is written blacklist data as Transaction Information in block chain, and given based on incentives strategy
It gives and uploads the client node account of the blacklist data and motivate logical demonstrate,prove accordingly.Can while realizing that blacklist is shared,
Guarantee the validity for the blacklist data being stored in block chain, and client node can be excited to area by incentives strategy
Block chain network uploads the enthusiasm of blacklist data, preferably realizes the shared of blacklist data.
Embodiment three
Fig. 5 is a kind of flow chart for blacklist sharing method based on block chain that the embodiment of the present invention three provides.This reality
Example is applied on the basis of the various embodiments described above, has carried out further optimization, shows in particular each client in block chain network
Node to block chain upload storage blacklist data, and inquiry blacklist data process, that is, realize each client node it
Between blacklist data shared procedure.Referring to Fig. 5, this method is specifically included:
S501, receive include blacklist data cochain transactions requests, cochain transactions requests be client node according to
What the blacklist data of storage generated.
S502 handles cochain transactions requests, and using blacklist data as in Transaction Information write-in block chain.
S503 updates the logical card of current excitations of client node account according to the incentives strategy in intelligent contract.
S504, blacklist data inquiry request in reception chain, blacklist data inquiry request is client node root on chain
It is generated according to query demand.
Illustratively, client node generates blacklist number on this chain according to its query demand for corresponding to financing corporation
According to inquiry request, it is sent to block chain network.For example, if the query demand of A financing corporation 40 is 2018 the 3rd in block chain
The blacklist data in season, then the client node 403 of company A can be according to the query demand, generate in inquiry block chain
Blacklist data inquiry request on the chain of the blacklist data in the third quarter in 2018 is sent to block chain network.Block link network
Current block in network generates node and receives blacklist data inquiry request on the chain.
It should be noted that the client node and S501 for generating blacklist data inquiry request on chain in this step
The middle client node for generating cochain transactions requests can be the same node, be also possible to different nodes, to this present invention
Embodiment is without limiting.
S505, according to the query demand on chain in blacklist data inquiry request, lookup and query demand from block chain
Matched blacklist data feeds back to client node as query result.
Illustratively, current block generation node can be according to the query demand on chain in blacklist inquiry request, in area
Lookup and the matched blacklist data of the inquiry request in all blacklist datas of block chain storage, and the black name that will be inquired
Forms data feeds back to the client node of blacklist data inquiry request in send chain as query result.Optionally, it is holding
On the row chain before blacklist data inquiry request, it can be first to the client for sending blacklist data inquiry request on the chain
End node carries out authentication, verifies whether it is the node in block network with search access right, if so, inquiring for it
Meet the blacklist data of query demand, otherwise, stops this data query operation, feedback query failed message.
Optionally, when to share the client node that includes in block chain network more for blacklist, and some client nodes
Between due to not reaching common agreement, so the blacklist data between them cannot be shared, need using isolation strategy
Carry out isolation processing.At this point it is possible to be the isolation that client node device in block chain network is carried out in the form of channel,
It can be and N in block chain network (N is greater than 1 positive integer) a client node is arranged in a channel, realize N number of
Being isolated between client node and remaining client node.For example, as shown in figure 4, the blacklist of the embodiment of the present invention is shared
Block chain network may further include D financing corporation, but due to financial D company without and A, B, C financing corporation reach share it is black
The common protocol of list data, therefore during block chain network of the building based on Fabric, it is public that A finance can be preset
Department 40, B financing corporation 41 and C financing corporation 42 are the same channel, and the shared of blacklist data can be carried out between them.
D financing corporation not in same channel is isolated.Optionally, for the blacklist data in same channel, in order to guarantee
The safety of the channel data, can blacklist data to same channel according to the preset rivest, shamir, adelman in the channel
After (SHA256 algorithm) signs to the blacklist data in the channel, signature is stored in the block head of block, is passed through
It signs in block head to carry out inquiring and authenticating to the blacklist data stored in the block, not due to rivest, shamir, adelman
Invertibity reduces leakage of data possibility.
Optionally, in the case where carrying out channel separation, according to the inquiry on the chain in blacklist data inquiry request
Demand searches with the matched blacklist data of the query demand as query result from block chain, and feeds back to the visitor
Family end node, comprising:
A, according to the gap marker on the query strategy and chain of intelligent contract in blacklist data inquiry request, tool is determined
There is the node identification collection of gap marker.
It wherein, further include query strategy in the intelligent contract of block chain, query strategy can be to define how to carry out
