The embodiment of the present invention is by being that ballot weight is arranged in each node according to the relevance of each node, and according to node
Corresponding ballot weight carries out common recognition verification to block, solve do not account in the prior art block chain network interior joint it
Between relevance the problem of, realize and common recognition verification carried out according to the relevance of node, improve the serious forgiveness of block chain network, simultaneously
Improve the flexibility of common recognition mechanism.
On the basis of the above embodiments, optionally, in the common recognition response message according to reception, and described in transmission
The ballot weight of node for response message of knowing together further includes before carrying out common recognition verification to the target block：Pass through block chain
Platform obtains the ballot weight of each node in the block chain network；Wherein, the block platform chain is previously according to each section
The node attribute information of point is ranked up according to the relevance of each node and setting destination node, and true according to ranking results
The ballot weight of fixed each node.
Specifically, block platform chain can be the isolated node for the node being different from block chain network, meanwhile, the block
Platform chain can be communicatively coupled with each node in block chain network, meanwhile, block platform chain can be based on intelligent contract
Operation, such as rewards and punishments and distribution information are managed to the node in block chain network.For example, block platform chain can be each section
Point provides token reward, and specific reward rule can be that the type for the Transaction Information being written according to each node and quantity determine reward
Token quantity, such as the corresponding value of Transaction Information type is big and/or the Transaction Information quantity of write-in is more, then the token rewarded
Quantity is also more.Each node is traded activity in block chain and needs to consume token simultaneously.
In a specific example, there are ten nodes in block chain network：Node A- nodes J.Each node is to area
Block platform chain sending node attribute information, for example, A nodes be written with " recorded with the record of transferring accounts of certain interbank, certain commodity logistics,
Certain buying and selling of commodities circulation record, certain associate's placement file etc. ", node B is equally written with the " note of transferring accounts with certain interbank
Record, certain commodity logistics record, certain buying and selling of commodities circulation record, certain associate's placement file etc. ", node C is written with " with certain silver
Record of transferring accounts in the ranks, certain commodity logistics record, certain buying and selling of commodities circulation records etc. ", node D is written with " with certain interbank
Transfer accounts record, certain associate's placement file etc. ", node E- nodes F is only written with " certain buying and selling of commodities circulation record etc. ", node
Any of above relevant information is not written by G- nodes J, is only written " register information of certain class certificate and certificate ".Block platform chain simultaneously
Think that the Maximum Value of the type of the Transaction Information of node A- nodes C write-ins and the quantity of Transaction Information, node G- nodes J are write
Secondly, the type of value of the Transaction Information of node E- nodes F write-ins is minimum, therefore to node for the type of value of the Transaction Information entered
The number of tokens of A- nodes C rewards is most, and secondly, the number of tokens of node E- nodes F is minimum by node G- nodes J.In addition, node is to area
Block platform chain obtains Transaction Information and needs payment token, if subsequently continuing that Transaction Information is written into block platform chain, block chain
Platform will continue to reward platform token to the node.
In the present embodiment, block platform chain can be according to the node that each node is sent in the block chain network received
Attribute information carries out clustering to each node, and according to clustering as a result, determining in block chain network except setting mesh
Each node except node is marked, respectively at a distance from setting destination node, so that it is determined that each node and setting destination node
The power of relevance.Can specifically it be arranged apart from smaller, relevance is stronger.Correspondingly, High relevancy node, weak rigidity node
It is that the ballot weight of High relevancy node is high, the ballot weight of weak rigidity node respectively with common association node ballot weight
It is low, the ballot weight of common association node can maintain an equal level it is constant, if for example, the ballot weight of setting destination node is set as 1,
Correspondingly, High relevancy node, weak rigidity node and common association node ballot weight are respectively：1.5,0.5,1.It needs
Bright, specific franchise weight values can be arranged as required to, but the cumulative and sum of ballot weight needs and block chain network
Interior joint sum is identical.Wherein, setting destination node can determine as in the previous example, or can also be random selection.
Wherein, node attribute information may include：The affiliated neck of the type of the affairs of node processing, the affairs of node processing
Domain, the geographical location of node, node processing the information such as the particular content of affairs.Block platform chain need in local cache or
The node attribute information that each node is sent is stored in local data base, after node changes corresponding node attribute information, block
Platform chain periodically updates node attribute information, redefines the ballot weight of each node, while being sent to block and generating section
Point.
As in the previous example, node is generated if node B is block, and node A is that setting destination node can be by area relative to node A
Block platform chain carries out clustering according to the node attribute information of each node to each node, and cluster analysis result is：Section
Point B- nodes D belongs to the High relevancy node of node A, and node E- nodes F belongs to common association node, and node G- nodes J belongs to
Weak rigidity node.Block platform chain can be with the ballot weight of distribution node A for 1, and the ballot weight of node B is 2, node C- power
The ballot weight of weight D is 1.5, and the ballot weight of node E- nodes F is 1, and the ballot weight of node G- nodes J is 0.5.
At this point, the method for salary distribution of ballot weight realizes, High relevancy node ballot weight is high, and weak rigidity node ballot weight is low, general
Logical associated nodes ballot weight is constant, and ensures the cumulative and identical as node total number of ballot weight, is 10.
It should be noted that the time of block platform chain transmission ballot weight and the object of transmission ballot weight can roots
It is configured, while can be added into intelligent contract according to needs, executing ballot weight according to intelligent contract sends operation.
Embodiment two
Fig. 2 is a kind of flow chart of block chain generation method provided by Embodiment 2 of the present invention, and the present embodiment is with above-mentioned reality
It applies and is embodied based on example, in the present embodiment, transaction request is embodied as trading processing request, while in root
According to the common recognition response message of reception, and the ballot weight of the node of the common recognition response message is sent, to the target
Before block carries out common recognition verification, further include：It determines in the Transaction Information recorded in the target block, at least one node
Associated transaction association parameter meets given threshold condition.
Correspondingly, the method for the present embodiment may include：
S210 is being after block generates node, to be given birth to according to the transaction request of reception by setting the election of common recognition mechanism
At target block.
The target block is sent in block chain network by S220, and receives the block chain network interior joint feedback
The common recognition response message for the target block.
S230 is determined in the Transaction Information recorded in the target block, with the associated transaction association of at least one node

The memory space accounted for.
In the present embodiment, transaction request is embodied as trading processing request, correspondingly, target block is basis
What trading processing requested to generate.Wherein, transaction association parameter can be for characterizing friendship associated with node in target block
The data volume of easy information, for example, the number of transaction record and/or memory space shared by transaction record (can be single with byte
Position).The associated transaction association parameter of each node can be counted in advance, and according to multiple transaction association parameters, judge that transaction is closed
Whether connection parameter meets given threshold condition.
S240 according to the common recognition response message of reception, and sends the ballot of the node of the common recognition response message
Weight carries out common recognition verification to the target block, wherein the ballot weight information of node is pre- according to the incidence relation between node
First determine.
In another optional embodiment of the invention, the common recognition response message according to reception, and send
The ballot weight of the node of the common recognition response message, common recognition verification is carried out to the target block, including：Obtain the common recognition
In response message, according to the corresponding node of response message that passes through of common recognition, and ballot weight corresponding with the common recognition node,
Calculate votes, wherein in the block chain network ballot weight of each node cumulative and with the block chain network
Node total number is consistent；If the votes meet setting ballot condition, it is determined that the target block is verified by knowing together,
And the target block is added in block chain.
Specifically, setting common recognition mechanism as practical Byzantium's common recognition algorithm PBFT.Further, the votes, which meet, sets
Surely it votes condition, including：If votes meet following formula, it is determined that the votes meet setting ballot condition：
Wherein, Y is votes, and N is node total number.
The node and the corresponding ballot weight pair of the node corresponding to response message passed through from there through statistics common recognition
Target block carries out common recognition verification, realizes and executes common recognition verification operation according to the poll after reasonable disposition ballot weight, makes common recognition
Verification process is more rationally accurate.
The embodiment of the present invention is believed by the way that transaction request is embodied as Transaction Information according to target area transaction in the block
Breath determines and the associated transaction association parameter of at least one node, and when transaction association parameter meets given threshold condition, presses
Common recognition verification is carried out to target block according to the ballot weight information determined according to the incidence relation between node, realizes targetedly root
Common recognition verification operation is executed according to transaction data, to improve the flexible of verification operation of knowing together of the block generated according to Transaction Information
Property, and improve the accuracy of the common recognition process of transaction data.
On the basis of the above embodiments, optionally, after generating target block according to the transaction request of reception,
Further include：If in the Transaction Information recorded in the target block, not with the associated transaction association parameter of at least one node
Meet given threshold condition, then according to the quantity for the response message passed through of knowing together in the common recognition response message of reception, to institute
It states target block and carries out common recognition verification.
It is understood that when the associated transaction association parameter of at least one node is unsatisfactory for given threshold condition, table
The relevance of Transaction Information and each node in bright target block is weak, and common recognition verification operation is carried out without ballot weight,
Original voting method, i.e. a node can be taken to correspond to a ticket, carry out common recognition verification.
In another optional embodiment of the invention, judges and whether the associated transaction association parameter of at least one node
Meet given threshold condition, including：It is corresponding according to each Transaction Information in the Transaction Information recorded in the target block
Vertex ticks counts the corresponding transaction association parameter of each node respectively, is closed as at least one associated transaction of node
Join parameter；From at least one associated transaction association parameter of node, maximum transaction association parameter is determined；If it is described most
Big transaction association parameter is more than or equal to given threshold, it is determined that in the Transaction Information recorded in the target block, at least one
A associated transaction association parameter of node meets given threshold condition；If the maximum transaction association parameter is less than setting threshold
Value, it is determined that discontented with the associated transaction association parameter of at least one node in the Transaction Information recorded in the target block
Sufficient given threshold condition.
Specifically, when other nodes of node into block chain network send trading processing request, asked in trading processing
Flag node information, after requesting to generate target block according to trading processing, the Transaction Information recorded in target block corresponds to
There is vertex ticks.The associated transaction association parameter of each node can be counted according to vertex ticks, and therefrom determine maximum transaction
Relevant parameter is compared with given threshold, to judge whether meet with the associated transaction association parameter of at least one node
Given threshold condition.For example, if transaction association parameter is transaction record, given threshold can be that target block transaction record is total
Several 80%.
It is understood that when maximum transaction association parameter is more than or equal to given threshold, show target area friendship in the block
The relevance highest of easy information node corresponding with maximum transaction association parameter, needs at this time using for characterizing incidence relation
Ballot weight carries out common recognition verification to target block.
In a specific example, node A- nodes J, each node broadcast oneself in block chain network as in the previous example
Transaction record, and vertex ticks is added on transaction record, which can uniquely determine corresponding node, i.e., every transaction
Record corresponds to a node by node identification.Wherein, transaction record can be numbered, is compared convenient for follow-up search.Other
The transaction record broadcasted in the block chain network received is stored in the transaction memory block of oneself by node.It is given birth in target block
At later, block generates the number of node B statistics each associated transaction record of node in target block.If there are a sections
The number of the associated transaction record of point is more than or equal to the 80% of the total number of the transaction record recorded in target block, then block is given birth to
At node B common recognition verification is carried out according to updated ballot weight；Otherwise according to the original ballot weight (franchise of each node
It is 1) to carry out common recognition verification again.
As in the previous example, in existing Byzantium knows together algorithm, block generates Node-B receiver to more than or equal to (2N+1)/3=7
The response message that the common recognition of a above node (10 nodes in total) passes through is to know together to pass through.In the present embodiment, if mesh
The transaction association parameter of mark block interior joint A meets given threshold condition, and (number of such as transaction record is more than or equal to total transaction and remembers
Record the 80% of number), according to node A, node B, node C- nodes D, node E- nodes F, the section obtained from block platform chain
The ballot weight of point G- nodes J is respectively 1,2,1.5,1,0.5 to carry out common recognition verification.If node G- node J failures, while only
There are node A, node C- nodes F to generate the response message that node B feedback common recognitions pass through to block.If being obtained at this time according to ballot weight
The common recognition result arrived is 1+2+1.5+1.5+1+1=8, meets and is more than 7 polls, that is, meet the cumulative of ballot weight and be more than etc.
InA node, common recognition pass through；If the ballot weight of node A- nodes J is respectively 1, it is total at this time according to what ballot weight obtained
Knowledge result is 1+1+1+1+1+1=6, is unsatisfactory for being more than or equal to 7 polls, that is, is unsatisfactory for the cumulative of ballot weight and is more than or equal toA node, common recognition do not pass through.
By the way that the threshold condition of transaction association parameter is arranged, and judged whether according to updated ballot according to threshold condition
Weight carries out common recognition verification to target block, and realization rationally flexibly carries out common recognition verification operation according to the ballot weight of relevance.
