Fig. 2 is a kind of Transaction Information confirmation method flow chart based on block chain provided in an embodiment of the present invention.This methodIt can be realized by system shown in FIG. 1, can specifically be realized by the block chain node in block chain meshed network.Such as Fig. 2Shown, this method specifically includes：
S210 receives the first Transaction Information that terminal is sent.
The terminal can refer to that operation has the terminal of client, for example, the client with wallet function.Between terminalAfter trading, which can be sent to block chain node, by the legitimacy of the block chain node verification transaction.Alternatively, the terminal can also refer to packaged service device, the packaged service device can by the Transaction Information generated in a period of time intoRow is packaged, and obtains the first Transaction Information, and the Transaction Information is sent to block chain link point and is verified.Wherein, transaction is believedBreath carries out being packaged the process that can be understood as generating new block.Wherein, block can be include block head and block main body, blockMain body is responsible for recording the Transaction Information in a period of time, and block head is mainly used for the upper block of connection, general all block structuresAt block chain, for example, the block head may include the cryptographic Hash of a upper block, which can also include the verifying of this blockInformation, such as can prove the random number of workload.
Specifically, which can be sent to block chain node, by block after determining Transaction Information by clientChain link point is verified, and is recorded in block chain after being verified.
Alternatively, client generate transaction after, can by trading card in block chain meshed network the whole network broadcast.It is packaged clothesBusiness device can recorde these trading cards, and by one of difficult math question of solution, to go to obtain creation new block right.It is createdThe packaged service device of new block right can be packaged the transaction generated in the whole network certain time, generate new block, andThe new block is sent to block chain node, is verified by block chain link point, records the new block after being verifiedIn block chain.At this point, the new block is the first Transaction Information.
Wherein, which can be sent to block chain meshed network by way of broadcast by terminal.It can alsoTo be only to be sent to the block chain node direct-connected with it by terminal.
Since same equipment may have client functionality and block chain nodal function simultaneously, or there is packing to take simultaneouslyBusiness device and block chain nodal function.The process that so step S210 may be equipment internal data transfer, that is, the client of equipmentEnd module is sent to block chain node module after determining Transaction Information, by the Transaction Information.
In addition, the Transaction Information may include diversified forms, it is specifically related with the field of block chain application.If the areaBlock chain is applied in digital cash field, then, which can indicate the information that both parties trade about digital cash,For example, the corresponding recipient address of the transaction, the side of producing address and transaction amount etc..If the block chain is applied in medical treatmentField, then, which can refer to clinician information, patient information, diagnostic message and prescription etc..
S220 determines validation of information cluster, so that the validation of information cluster confirms whether first Transaction Information accords withThe first prefabricated rule is closed, the validation of information cluster includes meeting specifying for the second prefabricated rule in the block chain meshed networkOdd number block chain node, the specified odd number are greater than 1.
In the concrete realization, it after determining the first Transaction Information, needs to be verified in validation of information cluster, with verifyingWhether first Transaction Information meets the first prefabricated rule.In one example, this first it is prefabricated rule for verify this firstWhether Transaction Information is correct.For example, whether the sequence of All Activity included in first Transaction Information is correct, first friendshipThe All Activity for including in easy information whether be true real transaction and verification result be by block chain node quantityIt is more than half etc. in the confirmation cluster.
Wherein, validation of information cluster can be determined according to the second prefabricated rule.The second prefabricated rule is specified for determiningOdd number block chain node is as validation of information cluster.In one example, which may include according to nodePosition and/or confidence values determine validation of information cluster.Wherein, the confidence values of block chain node predefine.For example, the nodeConfidence values can be calculated by the safety evaluation to node, the safety of the block chain node is higher, and confidence values are got overIt is high.
For example, the validation of information cluster can be determined centered on the block chain node direct-connected with terminal.
Specifically, the specified odd number block chain node for meeting the second prefabricated rule includes：It receives terminal and sends the first friendshipThe block chain node of easy information；And the block chain node confidence values height of the first Transaction Information is sent with reception terminal and is mutually facedClose block chain node.
For another example the validation of information cluster can be randomly assigned odd number confidence values height and adjacent to one another block chain linkPoint.
The specified odd number is generally higher than 1, for example, 3.
Each block chain node in validation of information cluster respectively verifies the first Transaction Information, is verified knotFruit；Each verification result can be synchronized in the block chain node that validation of information is concentrated.When verification result be by block chain linkWhen the quantity of point is more than half in confirming cluster, determine that Transaction Information closes rule.
Specifically, the block chain node direct-connected with terminal can believe first transaction after determining validation of information clusterThe mark of each block chain node is sent to other block chain nodes in confirmation cluster in breath and confirmation cluster.It is straight with terminalBlock chain node even verifies the first Transaction Information, is verified result.
Other nodes in validation of information cluster receive other block chain nodes (the block chain node direct-connected with terminal) hairThe mark of each block chain node in the first Transaction Information and the confirmation cluster sent；The Transaction Information is testedCard, is verified result；The verification result is sent to other block chain nodes in confirmation cluster；
When each block chain node in validation of information cluster determine verification result be by block chain node quantityWhen being more than half in the confirmation cluster, the Transaction Information is synchronized in the block chain meshed network.
In addition, the direct-connected block chain node of terminal receives the second transaction letter that other nodes in validation of information cluster are sentThe mark of each block chain node in breath and the confirmation cluster；Second Transaction Information is verified, knot is verifiedFruit；The verification result is sent to other block chain nodes in confirmation cluster；
When each block chain node in validation of information cluster determine verification result be by block chain node quantityWhen being more than half in the confirmation cluster, the second Transaction Information is synchronized in the block chain meshed network.
In addition, block chain node or terminal be after determining validation of information cluster, can by first Transaction Information andThe mark of each block chain node is sent to each block chain node in confirmation cluster in confirmation cluster.
Each node in validation of information cluster receives other block chain nodes (the block chain node direct-connected with terminal) hairThe mark of each block chain node in the first Transaction Information and the confirmation cluster sent；The Transaction Information is testedCard, is verified result；The verification result is sent to other block chain nodes in confirmation cluster；When in validation of information clusterEach block chain node determine verification result be by block chain node quantity in the confirmation cluster more than halfWhen, the Transaction Information is synchronized in the block chain meshed network.S230 is advised when first Transaction Information closesWhen, first Transaction Information is synchronized in the block chain meshed network.
In the concrete realization, after verifying the first Transaction Information and closing rule, block chain node can be believed according to first transactionBreath generates block, and the block is recorded in block chain and the whole network synchronizes the block, so that other block chain nodes are in the areaContinue to generate block on the basis of block.
Alternatively, if first Transaction Information is newborn block, after verifying the first Transaction Information and closing rule, block chainThe newly-generated block is recorded in block chain node and the whole network synchronizes the block, so as to the block in block chain meshed networkChain node continues to record on the basis of the newly-generated block.
