The alternative block and ballot incentive message (step 2) of signature.
After being kept accounts successfully due to accounting nodes, system can distribute reward, and the bonus for node of voting is from accounting nodes
It extracts, thus, in order to guarantee book keeping operation income, accounting nodes can be examined the ballot bonus for the ballot node for participating in ballot
Amount, to guarantee oneself benefit, i.e., each accounting nodes screen ballot corresponding with itself accounting nodes private key signature and save
Point private key signature set, wherein include ballot corresponding from different ballot nodes reward letter in ballot node private key signature set
Breath screens effectively ballot node private key signature set according to ballot incentive message from ballot node private key signature set, wherein
Effectively ballot node private key signature set includes effective vote node private key signature and corresponding effective ballot incentive message, by
In with multiple effective ballot nodes, thus, after effectively ballot node ballot, secondly also need multiple in comprehensive examination and evaluation block
Effectively ballot node ballot situation, i.e., judgement effectively ballot node private key signature set whether with preset selection condition
Match, and then determines the corresponding target accounting nodes (step of target effective ballot node private key signature set of successful match first
3), that is to say, that preliminary screening goes out the effectively corresponding target accounting nodes of the ballot universally recognized block of node.
Wherein, in one embodiment of the invention, ballot can be determined based on effective ballot number of nodes of approval
The universal degree of recognition of node, i.e., each accounting nodes obtain effective number of signatures in effectively ballot node private key signature set, will have
Effect number of signatures is compared with preset first threshold, it is first determined the target that effective number of signatures is equal to first threshold is voted
The corresponding node of node private key signature set is target accounting nodes.

The block including upper period Transaction Information generated, ballot node is for verifying with determination upper period Transaction Information
Whether vote.
Wherein, Transaction Information includes the mark such as both parties' node identification, transaction amount, tradable commodity title, exchange hour
Know the information of transaction uniqueness.
It is appreciated that each accounting nodes generate the alternative block comprising corresponding period Transaction Information within a upper period, and
And pretending to be in order to avoid other malicious nodes, the alternative block Jing Guo accounting nodes private key signature is broadcasted to block chain, wherein
Accounting nodes private key is only held by accounting nodes itself.Each ballot node obtains after alternative block according to the transaction being locally stored
Information verifies Transaction Information, if unanimously, showing that currency transaction information is true and reliable, thus, it is verified, this
When, after the completion of ballot, ballot incentive message corresponding with alternative block is generated, includes ballot amount of money award in the incentive message
And alternative block active account information etc., it broadcasts to block chain network by ballot node private key signature and accounting nodes private key
The alternative block and incentive message of signature, being verified at this time can be understood as voting successfully.
Certainly, exist ballot node it is not verified be alternative block stamp proof vote successfully, to seek illegal profit,
In order to avoid this kind of situation, in an embodiment of the present invention, before the generation of each period block, for a upper week
The ballot situation of the ballot node of phase is made whether the verifying that malice is voted.
Specifically, the upper period ballot node of each accounting nodes acquisition is broadcasted private by ballot node to block chain network
Key signature and accounting nodes private key signature alternative block and ballot incentive message, in order to according to ballot node private key signature and
The alternative block of accounting nodes private key signature further verifies whether related ballot node has carried out malice with ballot incentive message
Ballot, wherein as described above, alternative block is the area including upper period Transaction Information that each accounting nodes generate
Block, ballot node is for verifying to determine whether to vote upper period Transaction Information.
Step 102, each accounting nodes detect the corresponding different accounting nodes private key signatures of identical ballot node private key signature
Multiple alternative blocks in upper period Transaction Information it is whether identical, if it is different, then to block chain network broadcast through overregistering
The malice ballot nodal information of node private key signature, and a upper period for malice ballot node broke one's promise message and a upper period pair
The ballot incentive message answered.
It is understandable to be, it is that the transaction in the Transaction Information and alternative block according to itself storage is believed due to ballot node
What whether breath unanimously voted, thus, when ballot node throws the entirely different corresponding alternative block of Transaction Information
When ticket, it is clear that belong to malice voting behavior, thus, in an embodiment of the present invention, each accounting nodes detect identical ballot node
Whether the upper period Transaction Information in multiple alternative blocks of the corresponding different accounting nodes private key signatures of private key signature is identical,
If it is different, then showing that the ballot node has carried out malice and voted, to the broadcast of block chain network by accounting nodes private key signature
Malice ballot nodal information, wherein malice ballot nodal information includes the ID etc. of malice ballot node.
It in the present embodiment, include retracting its obtained ballot incentive message to the penalty mechanism of malice ballot node, because
And after determining malice ballot node, in order to implement to punish to it, it is also necessary to it is corresponding to obtain a period on malice ballot node
Ballot incentive message.Wherein, in order to which the loss for making up target accounting nodes also broadcasts malice ballot node in the present embodiment
A upper period break one's promise message, wherein message of breaking one's promise is for allowing target accounting nodes to know in its node of voting there is corresponding evil
Meaning ballot node.
Step 103, a upper period target accounting nodes determine malice ballot node, and with according to malice vote node
The ballot of a upper period broke one's promise message and corresponding ballot incentive message of the upper period, and then judge whether malice ballot node obtains
Took ballot incentive message corresponding with a upper period, however, it is determined that malice ballot node obtained corresponding ballot reward letter of the upper period
Breath then sent to break one's promise and punishes information and incentive message according to corresponding ballot incentive message of the upper period to malice ballot node
Retract control instruction.
Specifically, the target accounting nodes in upper period determine malice ballot node and with according to malice ballot node
The ballot of upper period was broken one's promise after message and corresponding ballot incentive message of the upper period, judge malice vote node whether obtain and
Upper period corresponding ballot incentive message, for example, determine whether ballot incentive message reaches malice and vote the account of node, if
Determined that malice ballot node obtained corresponding ballot incentive message of the upper period, then according to corresponding ballot reward letter of the upper period
Cease sent to malice ballot node break one's promise punish information and incentive message retract control instruction, wherein break one's promise and punish packet
Containing specific punishment content (such as the punishment amount of money, and do not pay up to break one's promise and punish information i.e. and can lose the notice of franchise broken one's promise
Information etc.).
In one embodiment of the invention, however, it is determined that malice ballot node does not obtain a period corresponding ballot prize
Information is encouraged, then breaks one's promise to malice ballot node transmission and punishes information, if target accounting nodes receive malice within a preset time
Information is punished in breaking one's promise for ballot node transmission, then shows that malice ballot node has received punishment, thus, it is wide to block chain network
The ballot authorization for broadcasting malice ballot node restores message, if being not received by the mistake that malice ballot node is sent within a preset time
Letter punishment information, then broadcast the ballot invalid message of malice ballot node to block chain network.
As a kind of possible embodiment, as shown in figure 4, the target accounting nodes in a upper period determine malice ballot section
Point, comprising:
Step 201, target accounting nodes to received malice by accounting nodes private key signature vote nodal information
It carries out parsing and obtains malice ballot node identification, and determining different accounting nodes corresponding from identical malice ballot node identification
The report number of signatures of private key signature.
Step 202, target accounting nodes will report that number of signatures is compared with preset threshold, if knowing report number of signature
Amount is more than or equal to preset threshold, it is determined that for malice ballot node.
Specifically, target accounting nodes determine whether ballot node is strictly to dislike according to the quantity that other accounting nodes are reported
Meaning ballot node, i.e., target accounting nodes to institute it is received by accounting nodes private key signature malice ballot nodal information progress
Parsing obtains malice ballot node identification, and determining different accounting nodes private keys corresponding from identical malice ballot node identification
The report number of signatures of signature, in turn, target accounting nodes will report that number of signatures is compared with preset threshold, if knowing act
Number of signatures is reported to be more than or equal to preset threshold, it is determined that be malice ballot node, at this point, preset threshold can be according to other book keeping operations
The quantity of node is arranged, and usual preset threshold is the value of the half of the quantity greater than other accounting nodes.
Step 104, if target accounting nodes receive the punishment letter of breaking one's promise that malice ballot node is sent within a preset time
Breath and incentive message then restore message to the ballot authorization that block chain network broadcasts malice ballot node, if within a preset time
It is not received by breaking one's promise for malice ballot node transmission and punishes information and incentive message, then broadcast malice to block chain network and vote
The ballot invalid message of node.
Specifically, if target accounting nodes receive breaking one's promise for malice ballot node transmission within a preset time and punish information
And incentive message, then show that malice ballot node has fulfiled penal system and retracted incentive message, thus, to block
The ballot authorization of chain network broadcast malice ballot node restores message, if being not received by malice ballot node within a preset time
Information and incentive message are punished in breaking one's promise for sending, then the ballot invalid message of malice ballot node is broadcasted to block chain network.
In one embodiment of the invention, to block chain network broadcast malice ballot node ballot invalid message it
Afterwards, voting results are generated in order to avoid the malice ballot node influences subsequent block, it is also necessary to the malice ballot node
Invalidation is made in ballot.
Specifically, each accounting nodes screen current period ballot node private corresponding with itself accounting nodes private key signature
Key signature set, wherein include ballot corresponding from different ballot nodes reward letter in the ballot node private key signature set
Breath deletes the malice from the ballot node private key signature set according to the ballot invalid message of malice ballot node
The private key signature of node of voting and corresponding ballot incentive message, acquisition filtering ballot node private key signature set are got rid of
The ballot of the malice ballot node.
In turn, each accounting nodes according to the corresponding ballot incentive message of remaining ballot node from the filtering vote node
Effectively ballot node private key signature set is screened in private key signature set, wherein effective ballot node private key signature set
Comprising node private key signature and the corresponding effective ballot incentive message of effectively voting, and judge effective ballot node private key
Whether signature set matches with preset selection condition, and then the target effective of successful match first in the determining current period
The corresponding target accounting nodes of node private key signature set of voting.
It should be noted that above-mentioned preset selection condition is different, and example is as follows according to the difference of application scenarios:
In one embodiment of the invention, ballot node can be determined based on the ballot number of nodes of remaining approval
Universal degree of recognition, i.e., each accounting nodes obtain the number of signatures in remaining effective ballot node private key signature set, will sign
Quantity is compared with preset first threshold, it is first determined the remaining target effective that number of signatures is equal to first threshold is voted
The corresponding node of node private key signature set be target accounting nodes, wherein first threshold can according to ballot number of nodes come
It determines, ballot number of nodes is higher, and the quantity of first threshold is higher, and in some possible examples, first threshold is greater than throwing
The quantity of the half of ticket number of nodes.
In another embodiment of the present invention, as it has been described above, each ballot node is held in related organization
There is equity side, thus, it is also based on the ballot weight of equity held quantity and determine each remaining ballot node, based on recognizing
Can total weight of remaining ballot node determine the ballot universal degree of recognition of node, i.e. each accounting nodes obtain effectively ballot node
Number of signatures in private key signature set, and the weighted value of different effectively ballot nodes, according to effective number of signatures and not
Weighted value with remaining effective ballot node calculates ballot value, for example, by the product value of the corresponding weighted value of each signature it
It is worth with as ballot, for another example, using the product value of the sum of weighted value and number of signatures as ballot value, as by ballot value and pre-
If second threshold be compared, it is first determined ballot value be equal to second threshold remaining target effective vote node private key label
It is target accounting nodes that name, which gathers corresponding node, wherein second threshold is usually total weight according to all ballot nodes
Value setting, total weighted value of all ballot nodes is higher, then second threshold is higher.
In the present embodiment, the corresponding weighted value of different remaining effective ballot nodes can be based on different characteristic informations
It determines, that is, obtains characteristic information of the different remaining effective ballot nodes in block chain network, this feature information can be stock
Power hold quantity or, nodal community (for example being personal node or agency node) etc., in turn, according to characteristic information determine
From the corresponding weighted values of remaining different effectively ballot nodes, for example, pre-establish the corresponding relationship of characteristic information and weighted value,
In turn, get remaining effective ballot node it is corresponding after, inquire the corresponding relationship, corresponding weighted value can be obtained.
Based on above description, in order to thoroughly eliminate voting mechanism, its throwing is no longer restored for the node of repeatedly malice ballot
Ticket power, in one embodiment of the invention, each accounting nodes are to the broadcast of block chain network by accounting nodes private key signature
Malice ballot nodal information, and mark malice ballot nodal information malice ballot cumulative frequency, when know malice ballot accumulation
Number reaches preset threshold, for example reaches three times, then disappears to the ballot authorization abolishment that block chain network broadcasts malice ballot node
Breath.
To sum up, the embodiment of the present invention based on block generate node availability detection method, it is only necessary to repeatedly broadcast be
It may achieve common recognition, determine that chain enters the block of block chain based on two kinds of mechanism of time and ballot, be no longer dependent on complicated common recognition machine
