Specific embodiment

Example embodiments are described in detail here, and the example is illustrated in the accompanying drawings.Following description is related to When attached drawing, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements.Following exemplary embodiment Described in embodiment do not represent all embodiments consistent with this specification one or more embodiment.Phase Instead, they are only some aspects phases with the one or more embodiments of as detailed in the attached claim, this specification The example of consistent device and method.

It should be understood that the sequence that might not show and describe according to this specification in other embodiments executes The step of correlation method.In some other embodiments, step included by method can than described in this specification more It is more or less.In addition, single step described in this specification, may be broken down into other embodiments multiple steps into Row description；And multiple steps described in this specification, it may also be merged into single step progress in other embodiments Description.

Fig. 1 is a kind of flow chart for event-handling method based on block chain that an exemplary embodiment provides.Such as Fig. 1 institute To show, this method is applied to participant, it may comprise steps of:

Step 102, the event participated according to the participant, Xiang Suoshu participant maintenance waiting list in addition pair The alternative sub- transaction answered.

In one embodiment, event is there are multiple participants, and each participant, which corresponds to, participates in object, which can Think individual, enterprise, tissue etc., this specification is limited not to this.Participating in object, there are corresponding digital identities, so that The electronic equipment for carrying the digital identity, which is equivalent to, is configured as participant corresponding to the participation object.

In one embodiment, the event of this specification may include any type, any scene of covering, such as ballot, label Conclude an agreement, assignment of traffic, transfer accounts, it is cross-border remittance etc., this specification is limited not to this.By taking ballot as an example, description information It may include the ballot information such as the origin of an incident and polling option, and each triggering information for participating in submitting in direction block chain may include To the selection result of polling option, to trigger completion ballot operation.

It in one embodiment, include the description information of event in alternative son transaction, the description information is for describing related thing The case where part, can implement corresponding event according to the description information when so that the alternative sub- transaction is processed.For example, description Information can characterize the execution logic of dependent event, related participant, shifting gears (such as to the state parameter of participant Increase or reduce the value of state parameter), variable quantity etc., this specification is limited not to this.In fact, the correlation of event Content can be linked up by first passing through any way between each participant in advance, then carry out drafting this by any participant The description information of event, allow other participants of event according to preparatory communication result to the content of the description information into Row is checked and is confirmed；Certainly, any participant can also voluntarily determine its of event in the case where not linking up in advance Other content in his participant and description information, this specification are limited not to this.

In one embodiment, the description information of event can be generated by any participant of the event, and it is any to be added to this Alternative sub- transaction in the waiting list of participant maintenance.And the description information that will additionally generate of any participant share to Other participants, so that other participants confirm description information.

In one embodiment, description information can be sent to other participations of event by any participant by chain outer tunnel Side.Description information is sent to other participants of event by chain outer tunnel, the high efficiency of transmission to description information may be implemented. Wherein, chain outer tunnel can be the encrypted tunnel established or the exit passageway of other forms between each participant of event, with It avoids that information leakage occurs.

In one embodiment, any participant can be by submitting a transaction to block chain, and the description above is believed Breath is contained in the transaction, so that the transaction is in all block chain nodes that can be sent in block chain after common recognition； And each participant of event can be configured as block chain node in block chain or each participant can be in block There are corresponding block chain node in chain, each participant is safeguarded by itself or corresponding block chain node The block chain account book full dose transaction data of block chain (block chain account book include), obtain above-mentioned transaction and it includes description letter Breath, so that the description above information is synchronized to other participants of event.

Step 104, according to several alternative sub- transaction chosen from the waiting list, corresponding set transaction is generated.

In one embodiment, multiple alternative sub- transaction be may include in set transaction, each alternative sub- transaction respectively corresponds In the event that above-mentioned participant is participated in, so that included is multiple alternative after set transaction is submitted to block chain Son transaction can be processed in block chain, so that these alternative sons are traded, corresponding multiple events are carried out.As it can be seen that It, can be with so that these alternative son transaction are committed to block chain in batches by including multiple alternative sub- transaction in set transaction The number of transaction submitted to block chain is reduced, without generating a block chain transaction for each alternative sub- transaction, is facilitated It reduces resource consumption, promote treatment effeciency.

It in one embodiment, can be when the alternative sub- transaction in the waiting list reaches preset quantity, described in selection Already present alternative sub- transaction (i.e. the alternative sub- transaction of preset quantity) in waiting list, to generate corresponding set transaction.? In another embodiment, already present alternative sub- transaction in the waiting list can be periodically chosen according to preset duration, with Generate corresponding set transaction；Certainly, there may be maximum limitations for the capacity of each set transaction, so that choosing in same period Alternative sub- transaction quantity there are corresponding maximum value, the part exceeded can be postponed until next period and be chosen.Certainly, Alternative son transaction can also be chosen by other preset rules, this specification is limited not to this.

In one embodiment, the alternative sub- transaction in waiting list can be arranged successively according to the addition moment, and every It is secondary successively to choose each alternative sub- transaction from front to back, the alternative sub- transaction being previously generated preferentially is chosen. Certainly, participant can also according to actual needs, such as urgency level, priority of event of event etc., in waiting list Alternative sub- transaction implement and sequentially unrelated selection operation；Alternatively, waiting list inherently can be according to above-mentioned urgent journey Degree, priority etc. are arranged, and can still be considered as successively choose in this way.

In one embodiment, participant can be each merging transaction addition number according to genesis sequence, make each merging Transaction is successively handled in block chain by the size according to reference numeral.In other words, block chain transaction is receiving participant After the merging transaction of submission, need to read the number that merging exchange includes；If number with it is previously processed merge trade Number is continuous, for example, newest processing merging transaction number be 99, the number of merging transaction that is currently received is 100, then may be used Be 100 to the number merging transaction handle；If it is between number and discontinuous, such as the merging transaction of newest processing Number be 99, be currently received merging transaction number be 101, then block chain node need wait and priority processing number is Then 100 merging transaction could handle the merging transaction that number is 101.It all may cause after being performed due to every transaction The state parameter of the participant changes, and the state parameter after the execution of rear transaction needs to rely on previously transaction execution Value, thus be necessary to ensure that each merging transaction is successively handled by the size according to reference numeral, so that each conjunction And transaction can be executed correctly.

Step 106, set transaction is committed to block chain, distinguishes the alternative sub- transaction in the set transaction It is handled.

In one embodiment, in the corresponding alternative sub- transaction of the event, all participants pair comprising the event The multi-party triggering information of the event；Wherein, when the multi-party triggering information passes through verifying, the corresponding alternative son of the event Transaction is triggered execution in block chain.Multi-party triggering information represents all participants recognizing for description information of event Can, and it is desirable that trigger event execution.For example, any participant of event generates description information and is sent to other participants Afterwards, other participants can be confirmed the content of description information, generate signature to description information by the identity key of itself and will The signature is back to any participant, and triggers each participant point that may include description information and event in information in many ways The signature not generated；Each signature belongs to the confirmation message that corresponding participant provides, and if using ciphertext numerical value, the confirmation Also by comprising the proof information to ciphertext numerical value, this is detailed below information.In short, by event in the present embodiment After any participant organizes the formation of multi-party triggering information, it is only necessary to will be added in any waiting list for participating in direction self maintained Corresponding alternative son transaction, and submit the set comprising the alternative sub- transaction to trade to block chain, and other participants are then not required to Implement to be processed similarly；Correspondingly, block chain node can be after triggering information in many ways be by verifying, for any participant The alternative sub- transaction submitted is handled.

In one embodiment, in the corresponding alternative sub- transaction of event, comprising the participant to the folk prescription of the event Trigger information；Wherein, when the folk prescription for the event that all participants of the event are submitted to block chain respectively triggers When information passes through verifying, the corresponding alternative sub- transaction of the event is triggered execution in block chain.Folk prescription triggers information table Bright corresponding participant adds their confirmation to the description information of event, it is desirable to the execution of trigger event；And each participant of event It requires to submit folk prescription triggering information to block chain respectively, so that the folk prescription that block chain node is submitted respectively based on all participants Trigger information, it is determined whether the indicated event of corresponding alternative son transaction should be executed.For example, any participant of event is raw At description information and after being provided to other participants, not only any participant needs to add into the waiting list of self maintained Corresponding alternative son transaction, other each participants are after adding their confirmation to description information, also respectively to the waiting of self maintained Corresponding alternative son transaction is added in queue；And each participant is based respectively on the waiting list generation set of self maintained Transaction, so that it is committed to block chain by the way that transaction will be gathered, so that above-mentioned folk prescription triggering information is submitted to block chain, for Block chain link point is verified.It in folk prescription triggering information may include description information and corresponding participant generate description information Signature；Signature belongs to the confirmation message that corresponding participant provides, and if confirmation message also includes permit using ciphertext numerical value Breath, this is detailed below.By submitting folk prescription to trigger information to block chain respectively from each participant, rather than it is a certain Participant submits multi-party triggering information, and the processing pressure mistake of single participant can be not only shared, prevented to processing pressure Greatly, it can also make each participant each to what is participated according to the actual conditions (such as processing pressure, priority management etc.) of itself Event carries out selectively processing even batch processing.

In one embodiment, the description information of event may include variable quantity, and the event may be used to each ginseng Value variation occurs according to the variable quantity with the state parameter of side's corresponding record on block chain, for example increases value, reduce Value etc..Wherein, according to the type of event or scene difference, corresponding state parameter may also be different, for example transfer accounts or cross-border State parameter under scene of remitting money can be the account balance of participant, and the state parameter under assignment of traffic scene can be with for another example For the number for the residual flow that participant is held, this specification is limited not to this.

In one embodiment, the value of the corresponding state parameter of each participant, the variable quantity can be plaintext numerical value. Block chain node in block chain safeguards there is block chain account book respectively, and record has full dose transaction data in the block chain account book, makes The value of the corresponding state parameter of each participant can be known by obtaining block chain node；Further, any participant can To submit a transaction to block chain, which includes above-mentioned triggering information, so that the transaction can be by base after common recognition In the corresponding state parameter of any participant value, above-mentioned variable quantity and execute so that any participant is corresponding State parameter can based on the variable quantity and realize value change.

In one embodiment, the value of the corresponding state parameter of each participant, the variable quantity are respectively to be based on homomorphism The ciphertext numerical value that Encryption Algorithm or Homomorphic Commitment algorithm are calculated.For homomorphic encryption algorithm, any class can be used The homomorphic encryption algorithm of type, as long as ensuring that the homomorphic encryption algorithm can satisfy additive homomorphism, so that even in ciphertext state Under, it still is able to so that the value of state parameter increases or decreases the variable quantity；It is additive homomorphism for the homomorphic encryption algorithm Encryption Algorithm or full homomorphic encryption algorithm, this specification are limited not to this.For Homomorphic Commitment algorithm, work as use When Pedersen promise mechanism in the related technology, can determine a random number for clear data, and based on the random number with Clear data carries out that corresponding commitment data is calculated, which can be by as above-mentioned ciphertext numerical value.

In one embodiment, when the value of state parameter, variable quantity are ciphertext numerical value, participant needs to provide relevant Information is proved, so that block chain node when executing relationship trading, can determine the legal validity of transaction.For example, participating in Side needs to provide proof to variable quantity, to show that the variable quantity is in correct value section, for example [0,2⁶⁴).For another example working as When event is used for so that according to the variable quantity value reduction occurs for a certain participant corresponding state parameter, i.e., transaction purpose is to make The value for obtaining the state parameter of a certain participant reduces the variable quantity, which, which provides, takes state parameter The proof of value and variable quantity, to show the value of state parameter not less than value reduction amount (the value reduction amount and above-mentioned change Change amount is equivalent).

In one embodiment, (Range Proof) technology can be proved using section in the related technology, for example Bulletproofs scheme or Borromean ring signatures scheme etc., generate above-mentioned proof information, this specification not to this into Row limitation.

In one embodiment, for any participant when generating description information, the variable quantity in the description information can be close Literary numerical value.It, can be according to the plaintext numerical value according to Pedersen promise mechanism such as when the plaintext numerical value of variable quantity is t1 T1 ciphertext corresponding with random number r1 generation promises to undertake T1, and may include T1, t1 and the r1 in description information, so that its of event His participant can verify the corresponding relationship between ciphertext promise T1 and plaintext numerical value t1, random number r1.Wherein, in description information Plaintext numerical value t1 and random number r1 can be encrypted, such as when description information needs to be sent to participant X, it can To be encrypted using the corresponding identity public key of digital identity of participant X, respectively obtain encrypted Enc_X (t1), Enc_X (r1) is simultaneously added in description information, consequently only that participant X can by itself identity private key to Enc_X (t1), Enc_X (r1) is decrypted to obtain above-mentioned plaintext numerical value t1 and random number r1, has been obviously improved Information Security.Certainly, it removes Using except public key encryption mode, can also using any other cipher mode, such as digital envelope etc. in the related technology, This specification is limited not to this.

In one embodiment, when there are other multiple participants, description information can separately include corresponding to it is each its The encrypted data of his participant.For example, when other parameters side includes participant X and participant Y, it can be according to participant X Identity public key plaintext numerical value t1, random number r1 encrypted respectively obtain Enc_X (t1), Enc_X (r1), and according to participant The identity public key of Y encrypts plaintext numerical value t1, random number r1 respectively obtains Enc_Y (t1), Enc_Y (r1), and by Enc_X (t1), Enc_X (r1), Enc_Y (t1) and Enc_Y (r1) are added in description information, so that any participant only needs Prepare a description information and is respectively sent to other each participants, it is different without preparing for other each participants Description information.Certainly, any participant can prepare different description informations for other each participants, such as It is sent in the description information of participant X comprising Enc_X (t1) and Enc_X (r1), and in the description information for being sent to participant Y In include Enc_Y (t1) and Enc_Y (r1), this specification is limited not to this.

In one embodiment, for the variable quantity for the ciphertext state for including in description information, may include in set transaction First proves information, and the first proof information is for proving that the variable quantity is in correct value section.When any participant is raw At event description information when, which can also generate the first proof information, so that either generating multi-party triggering Information or folk prescription trigger information, do not need other participants and generate other proof information for the value of the variable quantity. Certainly, each participant can also be respectively that (the corresponding variable quantity of each participant may be different for corresponding variable quantity；Such as In cross-border remittance scene, it is potentially based on different currency types and the value of variable quantity is caused to have differences) generate the first permit Breath, this specification are limited not to this.

In one embodiment, if the event is for making a certain participant of event, (there may be multiple similar ginsengs With side) corresponding state parameter occurs value according to the variable quantity and reduces, then needing to prove comprising second in set transaction Information, the second proof information are used to prove the value of the corresponding state parameter of a certain participant not less than value reduction amount. For triggering information in many ways, each participant of event can be according to the variable quantity in the state parameter for determining itself In the case where value reduction occurs, corresponding second proof information is generated respectively and is provided to above-mentioned any participant, by this Any participant organizes the formation of multi-party triggering information；Alternatively, can unify to generate the second proof information, nothing by any participant Each participant is needed to be individually created.It can be certainly by generating the participant of folk prescription triggering information for folk prescription triggers information Body, which generates second, proves information.

In one embodiment, when a certain participant is itself to generate second to prove information, the participant is first according to certainly Other events that body participates in carry out value update to itself corresponding state parameter, are then joined according to the updated state of value Number, which generates second, proves information.For example, when the value of state parameter, variable quantity are ciphertext numerical value, and the event be used for so that When according to the variable quantity value reduction occurs for the participant corresponding state parameter, which needs according to previously processed Transaction, determines the value of itself corresponding state parameter, so that generating correct second proves information, to ensure dependent event energy It is enough smoothly to be executed.

For example, block chain node after receiving the set transaction that each participant is submitted, extracts in set transaction and includes Alternative son transaction, and the triggering information (multi-party triggering information or folk prescription triggering information) for including for alternative son transaction is confirmed And verifying.When triggering information includes the corresponding confirmation message of all participants of event or owning for the event in many ways Participant has had been filed on corresponding folk prescription triggering information, and (each folk prescription triggering information separately includes the confirmation letter of corresponding participant Breath) when, it, can be by the event flag if the multi-party triggering information or all folk prescriptions triggering information have passed through verifying For success status；Similarly, it can be status of fail by unverified event flag, will not received in effective period of time The event flag of the corresponding confirmation message of all participants is timeout mode etc., and the state of each event is then committed to block In chain.By taking a certain participant of event as an example, which, can be by inquiring block chain account book before submitting set transaction On transaction record, determine the state for each event that itself is participated in, such as the transaction for status of fail or timeout mode needs Will the value to state parameter restored accordingly (such as the participant be transferor when, need to corresponding account balance Carry out rollback), for the transaction of success status need to update state parameter (such as the participant be beneficiary when, need to phase The transfer amounts answered are collected money, are increased in account balance), then according to value after the update of state parameter, generate related Second proof information (ensure that the second proof information is the newest value based on state parameter and generate) of event, then generates simultaneously Above-mentioned set is submitted to trade.

In one embodiment, when the event includes transferring accounts event, the participant of the event includes: transferor and receipts Money side, the variable quantity include: the volume of transferring accounts, and the state parameter includes: account balance；In other words, it is equivalent to from remittance direction Beneficiary implements transfer operation, so that the account balance of transferor reduces volume of transferring accounts accordingly, the account balance of beneficiary increases Corresponding volume of transferring accounts.For example, may include the account address of transferor, the account address of beneficiary, volume of transferring accounts in description information (commitment value), volume of transferring accounts (encrypted state), random number (encrypted state) etc. in plain text, to show from the account address of transferor to receipts Shift the volume of transferring accounts in the account address of money side.

In one embodiment, when the event includes the first remittance event, the participant of the event includes: remittance Side, relaying side, beneficiary, the variable quantity include: between the transferor and the relaying side based on first kind assets First transfers accounts between volume, the relaying side and the beneficiary second transferring accounts volume based on Second Type assets, the state ginseng Number includes: account balance；In other words, be equivalent between transferor and relaying side shift the first kind assets (such as Hongkong dollar), Assets volume is first to transfer accounts volume, and the assets (such as dollar) of transfer Second Type, assets volume between relaying side and beneficiary It transfers accounts volume for second, and according to the exchange rate between the first kind and the assets of Second Type, so that first transfers accounts volume and second turn The corresponding assets value of account volume is almost the same, transfers accounts volume (then the account balance for being finally equivalent to transferor reduces first The assets of one type), the account balance of beneficiary increase second and transfer accounts volume (assets of Second Type), and the account of relaying side Remaining sum increase first transfer accounts volume (assets of the first kind) and reduce second transfer accounts volume (assets of Second Type), in assets It is equivalent in value and does not change.

In one embodiment, when the event includes the second remittance event, the participant of the event includes: remittance Side, n relaying side, beneficiary, the variable quantity include: to be provided between the transferor and the 1st relaying side based on the first kind Volume of transferring accounts, n-th of relaying side between volume of transferring accounts, (i-1)-th relaying side and i-th of the relaying side produced based on the i-th type assets Based on the volume of transferring accounts of the (n+1)th type assets between the beneficiary, the state parameter includes: account balance；Wherein, 1 < i ≤n.As n=1, the second remittance event of the present embodiment is equivalent to the first remittance event of above-described embodiment, no longer superfluous herein It states.As n > 1, since there are multiple relaying sides, thus for the first remittance event of above-described embodiment, also include Assets transfer process between multiple relaying sides；By taking n=2 as an example, the participant of event includes transferor, relaying side 1, relaying side 2, beneficiary, in which: the assets (such as Hongkong dollar) of the first kind are shifted between transferor and relaying side 1, assets volume is first turn Account volume, shifts the assets (as Euro) of Second Type, assets volume is second to transfer accounts volume between relaying side 1 and relaying side 2, in After the assets (such as dollar) of third type are shifted between side 2 and beneficiary, assets volume is that third is transferred accounts volume, and according to the first kind The exchange rate 1, Second Type between the assets of Second Type and the exchange rate 2 between the assets of third type, so that first transfers accounts Volume, the second volume and third corresponding assets value of volume of transferring accounts of transferring accounts are almost the same, then being finally equivalent to more than the account of transferor Volume reduce first transfer accounts volume (assets of the first kind), beneficiary account balance increase third and transfer accounts volume (third type Assets), and the account balance of relaying side 1 increases first and transfers accounts and volume (assets of the first kind) and reduces second and transfer accounts volume It (assets of Second Type), is equivalent in assets value and does not change, the account balance of relaying side 2 increases second and transfers accounts Volume (assets of Second Type) and reduce third transfer accounts volume (assets of third type), be equivalent in assets value and do not occur Variation.

In one embodiment, when the value of state parameter, variable quantity use ciphertext numerical value, include in the set transaction Alternative sub- transaction also set change preceding state value, variation after state value it is described so that after the alternative sub- transaction is processed The state parameter of participant is changed to state value after the variation by state value before the variation via the amount of state variation； Wherein, state value is respectively to be based on homomorphic encryption algorithm after state value and the variation before the amount of state variation, the variation Or the ciphertext numerical value that Homomorphic Commitment algorithm is calculated.Correspondingly, each standby to include in set transaction when block chain node Choosing son transaction is when being verified, therefore, to assure that adjacent alternative sub- transaction meets: shape after the corresponding variation of previous alternative sub- transaction State value is identical before state value variation corresponding with latter alternative sub- transaction, otherwise will be determined as authentication failed.

With embodiment illustrated in fig. 1 correspondingly, Fig. 2 is another thing based on block chain that an exemplary embodiment provides The flow chart of part processing method.As shown in Fig. 2, this method is applied to block chain node, may comprise steps of:

Step 202, the set transaction that participant is committed to block chain is received, includes from the participation in the set transaction Several alternative sub- transaction chosen in the waiting list just safeguarded, the alternative sub- transaction correspond to what the participant was participated in Event.

Step 204, the set transaction is executed, handled respectively the alternative sub- transaction in the set transaction.

In order to make it easy to understand, below by taking cross-border remittance scene as an example, to the technology of this specification one or more embodiment Scheme is illustrated.Technical solution based on this specification, several remittances that each mechanism can respectively participate in itself are handed over Easily (be equivalent to above-mentioned alternative sub- transaction) and merge into a block chain transaction (being equivalent to above-mentioned set transaction), and pass through to Block chain submits the block chain to trade, and realizes and the batch of several money transfer transactions is submitted and handled.Single will be converged first below The generation of money transaction is described with treatment process, then extends to the batch processing of more money transfer transactions.

Fig. 3 is a kind of schematic diagram of a scenario for cross-border remittance that an exemplary embodiment provides.As shown in Figure 3, it is assumed that by with Family 1 carries out block chain remittance to user 2；Wherein, " user " in this specification can show as logged in user account, and The user account can actually belong to individual or entity, and this specification is limited not to this.It is assumed that user 1 is in national A Mechanism 1 at offer clients fund account 1, user 2 offers clients fund account 2, this explanation at the mechanism 4 of national B In the case that book directly can not implement cross-border remittance between mechanism 1 and mechanism 4, pass through the assistance of mechanism 2 and mechanism 3 The operation of the cross-border remittance is realized on block chain.

Mechanism 1, mechanism 2, mechanism 3 and mechanism 4 are respectively present corresponding equipment 1, equipment 2, equipment 3 and equipment 4, and pass through The client-side program that block chain is run in equipment 1~4, so that equipment 1~4 is configured as corresponding block chain node；Accordingly Ground, mechanism 1~4 can realize operation relevant to block chain by equipment 1~4.For example, mechanism 1~4 can be respectively by setting Standby 1~4 submits corresponding block chain transaction to block chain；There is the full dose on block chain to hand over for another example equipment 1~4 is safeguarded respectively Easy data, i.e. block chain account book allow mechanism 1~4 to inquire and safeguard accordingly respectively the remaining sum number of each block chain account According to, for example the corresponding block chain account Y1 of mechanism 1 holds 1000 Hongkong dollars, the corresponding block chain account Y2 of mechanism 2 holds 2500 ports Coin and 4200 Euros, the corresponding block chain account Y3 of mechanism 3 holds 3000 Euros and 2000 dollars, the corresponding block chain of mechanism 4 Account Y4 holds 1500 dollars etc..

The considerations of for secret protection etc., the balance data of block chain account Y1~Y4 is often not with plaintext version It is safeguarded, but uses corresponding ciphertext data.By taking block chain account Y1 as an example, it can be registered as in block chain account book (currency_1, PC (a, r_a), Enc_A (a), Enc_A (r_a)), in which: currency_1 indicates that currency type is Hongkong dollar, It is the corresponding random number of a that a expression Hongkong dollar number, which is 1000, r_a, and PC (a, r_a) is by Pedersen promise mechanism to a and r_ The commitment value for the ciphertext form that a is calculated, Enc_A (a), Enc_A (r_a) are respectively the ciphertext value (ratio of a and r_a It can such as be encrypted using the identity public key of mechanism 1, or the Encryption Algorithm of any other form can be used).Block chain Account Y2 can be registered as (currency_1, PC (b1, r_b1), Enc_B (b1), Enc_B (r_b1)), (currency_2, PC (b2, r_b2), Enc_B (b2), Enc_B (r_b2)), in which: b1 indicate Hongkong dollar number be 2500, r_b1 be b1 it is corresponding with Machine number, currency_2 indicate currency type be Euro, b2 indicate an Euro number be 4200, r_b2 is the corresponding random number of b2. Block chain account Y3 can be registered as (currency_2, PC (c1, r_c1), Enc_C (c1), Enc_C (r_c1)), (currency_3, PC (c2, r_c2), Enc_C (c2), Enc_C (r_c2)), in which: c1 indicates that Hongkong dollar Euro is 3000, r_c1 For the corresponding random number of c1, currency_3 indicates that currency type is dollar, and c2 indicates that dollar amount is 2000, r_c2 is c2 pairs The random number answered.Block chain account Y4 can be registered as (currency_3, PC (d, r_d), Enc_D (d), Enc_D (r_ D)), wherein d indicates that dollar amount is 1500, r_d is the corresponding random number of d.

Based on remittance scene shown in Fig. 3, Fig. 4 is that the interaction in a kind of cross-border money transfer process of an exemplary embodiment is shown It is intended to.As shown in figure 4, the interactive process of cross-border remittance may comprise steps of:

Step 401, equipment 1 drafts money transfer transactions tx_i.

In one embodiment, it is assumed that user 1 wishes 500 Hongkong dollars of remitting money to user 2, which can be by mechanism 1 Clients fund account 1 500 Hongkong dollar is provided, and user 2 can be collected by the clients fund account 2 at mechanism 4 by one Determine the dollar after the exchange rate calculates.

In one embodiment, mechanism 1 can take off 500 Hongkong dollars from the corresponding clients fund account 1 of user 1；And machine Structure 1 needs itself determining remittance routing between mechanism 4, for example the remittance routing in Fig. 4 is " 1 → mechanism, mechanism, 2 → machine 3 → mechanism of structure 4 " allows mechanism 1 to mechanism 2 to be transferred to 500 Hongkong dollars, mechanism 2 and can be transferred to 56 Euros to mechanism 3 and (is equivalent to 500 Hongkong dollars), mechanism 3 64 dollars (being equivalent to 56 Euros, 500 Hongkong dollars) can be transferred to mechanism 4, and finally from mechanism 4 to user 2 corresponding clients fund accounts 2 are transferred to 64 dollars, to complete remittance operation.Wherein, mechanism 1 takes off from clients fund account 1 500 Hongkong dollars, mechanism 4, which to clients fund account 2 are transferred to 64 dollars and belong to outside chain, to be operated, and then passes through area between 1~mechanism, mechanism 4 Block chain realizes fund transfer on chain.

In one embodiment, in above-mentioned remittance routing " 1 → mechanism, mechanism, 2 → mechanism, 3 → mechanism 4 ", mechanism 1 and machine Between structure 4 there are 2 relaying sides be mechanism 3 and mechanism 4；And in other embodiments, the quantity of the side of relaying can be 1,3 Or 3 or more, this specification is limited not to this.

Wherein, address Z1~Z4 is used to show the participant of this remittance event, so that subsequent from address Z1~Z4 Corresponding block chain account Y1~Y4 implements remittance of transferring accounts.

In (currency_1, PC (t1, r_t1), Enc_B (t1), Enc_B (r_t1), Enc_C (t1), Enc_C (r_ T1), Enc_D (t1), Enc_D (r_t1)) in, t1 indicates transfer amounts (the 500 such as above-mentioned ports from address Z1 to address Z2 Coin), r_t1 is the corresponding random number of amount of money t1, and PC (t1, r_t1) is calculated based on amount of money t1 and random number r_t1 Commitment value, Enc_B (t1) expression carry out encrypted ciphertext numerical value, Enc_C (t1) table to amount of money t1 with the identity public key of mechanism 2 Show the identity public affairs for carrying out encrypted ciphertext numerical value, Enc_D (t1) expression mechanism 4 to amount of money t1 with the identity public key of mechanism 3 Key carries out encrypted ciphertext numerical value to amount of money t1；Similarly, Enc_B (r_t1), Enc_C (r_t1), Enc_D (r_t1) difference To carry out encrypted ciphertext numerical value to amount of money t1 by the identity public key of mechanism 2, mechanism 3, mechanism 4.(currency_2,PC (t2,r_t2),Enc_B(t2),Enc_B(r_t2),Enc_C(t2),Enc_C(r_t2),Enc_D(t2),Enc_D(r_t2)) (currency_3, PC (t3, r_t3), Enc_B (t3), Enc_B (r_t3), Enc_C (t3), Enc_C (r_t3), Enc_D (t3), Enc_D (r_t3)) the case where it is similar, details are not described herein again.Rate1, rate2 be respectively currency_1 with The exchange rate, the exchange rate of currency_2 and currency_3 of currency_2.Time is the transaction moment.And, it is also possible to exist Data needed for some other transaction, this can will not enumerate herein with reference to scheme in the related technology.

The section that RP_t1, RP_t2, RP_t3 respectively correspond to transaction amount t1, t2, t3 proves, to be respectively used to demonstrate,prove Bright transaction amount t1, t2, t3 are in correct value section, such as 1≤t1 < 2⁶⁴, 1≤t2 < 2⁶⁴, 1≤t3 < 2⁶⁴.Wherein, if Standby 1, which can generate above-mentioned section by zero-knowledge proof technology in the related technology, proves, this specification is not to this progress Limitation.

And if using plaintext numerical value, in the money transfer transactions details of money transfer transactions tx_i, above-mentioned and transaction amount Relevant cipher-text information may alternatively be cleartext information relevant to transaction amount, for example, (currency_1, t1), (currency_2, t2), (currency_3, t3), rate1, rate2, time ... }, and without being proved comprising above-mentioned section The contents such as RP_t1, RP_t2, RP_t3.

Money transfer transactions details are synchronized to equipment 2, equipment 3 and equipment 4 by step 402a~402c, equipment 1 respectively.

In one embodiment, after equipment 1 can sign to money transfer transactions details by the identity private key of mechanism 1, lead to It crosses outer (or being, under the chain) channel of chain and is respectively sent to 2~equipment of equipment 4, to realize that data are synchronous.

In one embodiment, 1~equipment of equipment 4 is separately operable the client-side program of block chain, so that 1~equipment of equipment 4 are respectively configured as the block chain node in block chain；Alternatively, 1~equipment of equipment 4 is respectively present corresponding area in block chain Block chain node, this specification are limited not to this.Wherein, each block chain node in block chain safeguards there is content respectively Unified block chain account book, record has the block chain data of full dose in block chain account book.Therefore, a friendship can be generated in equipment 1 Easily, the content of the transaction includes the money transfer transactions details of above-mentioned money transfer transactions tx_i, and the transaction is committed in block chain；Phase Ying Di, after the transaction is by common recognition, each block chain node that can be sent in block chain, for each block chain link Point updates the block chain account book of self maintained.Therefore, equipment 1, equipment 2, equipment 3 and equipment 4 can be corresponded to by itself respectively The block chain account book safeguarded of block chain node, the above-mentioned transaction that equipment 1 is submitted is known, to obtain in the transaction and include The money transfer transactions details of above-mentioned money transfer transactions tx_i.

Certainly, equipment 1 is also possible to that money transfer transactions data are synchronized to 2~equipment of equipment 4, this specification by other means It is limited not to this.

The corresponding money transfer transactions tx_i of money transfer transactions details is added to the local queue 1 of itself by step 403a, equipment 1.

In one embodiment, when equipment 1 sends money transfer transactions details by chain outer tunnel, equipment 1 can be directly to this Money transfer transactions tx_i is added in ground queue 1；Certainly, equipment 1 can finish the confirmation of money transfer transactions details with 2~equipment of waiting facilities 4 And after returning to corresponding confirmation response, money transfer transactions tx_i just is added to local queue 1, to ensure that 2~equipment of equipment 4 both participates in To money transfer transactions tx_i.

In one embodiment, when money transfer transactions details are synchronized to 2~equipment 4 of equipment by block chain by equipment 1, equipment 1 equally will receive the money transfer transactions details synchronous on block chain, then equipment 1 can both test the money transfer transactions details It demonstrate,proves (verification process can refer to step 403b), and by the way that money transfer transactions tx_i is added to local queue 1 after verifying, it can also be with Determining that the money transfer transactions details correspond to money transfer transactions tx_i, money transfer transactions tx_i and by the equipment 1 itself drafted and submitted When to block chain, the verification process to money transfer transactions details is omitted, and is added directly to local queue 1.

Step 403b adds it to the local queue of itself after equipment 2 verifies the money transfer transactions details received 2。

In one embodiment, equipment 2 needs to implement verification operation after Transaction Details of receiving a remittance, comprising: equipment 2 is logical Cross Enc_B (t1), Enc_B (r_t1), Enc_B (t2), Enc_B (r_ that the identity private key of itself includes to money transfer transactions details T2), Enc_B (t3), Enc_B (r_t3) are decrypted, and obtain corresponding amount of money t1 and random number r_t1, amount of money t2 and random number R_t2, amount of money t3 and random number r_t3, and separately verify PC (t1, r_t1)=r_t1G+t1H, PC (t2, r_t2)=r_t2G+ Whether t2H, PC (t3, r_t3)=r_t3G+t3H are true, and wherein G, H are system parameter；Equipment 2 verify currency_1 with Whether it is rate2 that whether the exchange rate between currency_2 is the exchange rate between rate1, currency_2 and currency_3； Equipment 2, which verifies section, proves whether RP_t1, RP_t2, RP_t3 are correct etc..After determining money transfer transactions details by verifying, if Standby 2 can add corresponding money transfer transactions tx_i to the local queue 2 of self maintained, and to equipment 1 return confirmation response, with Show to receive corresponding money transfer transactions.

Certainly, if using plaintext numerical value, above-mentioned decryption, commitment value verifying, section checking be can be omitted Core is carried out to the value of the address of the block chain account of each participant, t1, t2, t3, rate1, rate2 Deng operation, such as only It is right.

After step 403c-403d, equipment 3-4 respectively verify the money transfer transactions details received, add it to certainly The local queue 3-4 of body.

In one embodiment, the operation and equipment 2 that equipment 3, equipment 4 are implemented are similar, no longer repeat one by one herein.

So far, money transfer transactions tx_i is added separately to the local queue 1~4 respectively safeguarded by 1~equipment of equipment 4 In.Similarly, it (is not necessarily 1~equipment of equipment 4 when 1~equipment of equipment 4 participates in other money transfer transactions respectively while joining With money transfer transactions) when, equally can be using being similar to the processing mode of above-mentioned money transfer transactions tx_i, to corresponding local team Money transfer transactions are added in column, for the transaction polymerization and batch processing in following step.

Step 404a, for equipment 1 according to the money transfer transactions in local queue 1, polymerization generates transaction TX_a, and mentions after signature It hands over to block chain.

As described above, similar with money transfer transactions tx_i, mechanism 1 may also participate in other money transfer transactions, such as When a certain user needs to remit money by mechanism 1 to another user, equipment 1 can pass through the side similar to above-mentioned steps Formula drafts corresponding money transfer transactions, money transfer transactions details are sent to other each mechanisms are verified, into local queue 1 Add corresponding money transfer transactions tx_i.Meanwhile mechanism 1 is also used as the relaying side of some money transfer transactions (similar to mechanism 2-3 Role in the above-described embodiments) or beneficiary (similar to the role of mechanism 4 in the above-described embodiments), so that the mechanism 1 can To receive the remittance that the transferor (similar to the role of mechanism 1 in the above-described embodiments) of these money transfer transactions is sent by equipment 1 Money Transaction Details, and corresponding money transfer transactions are added into local queue 1 after being verified.

Therefore, many money transfer transactions participated in the local queue 1 that equipment 1 is safeguarded comprising mechanism 1.And equipment 1 can be with It rule is selected according to predefined transaction, chooses one or more money transfer transactions from local queue 1 every time, and to being selected Money transfer transactions are polymerize, and a block chain transaction is generated.

For example, Fig. 5 is a kind of signal for block chain transaction content based on ciphertext numerical value that an exemplary embodiment provides Figure.As shown in Figure 5, it is assumed that equipment 1 chooses 4 money transfer transactions every time and is polymerized to a block chain transaction, such as money transfer transactions Tx_11, tx_12, tx_13, tx_14 are polymerized to the transaction of block chain TX_1, money transfer transactions tx_21, tx_22, tx_23, tx_24 It is polymerized to block chain transaction TX_2, money transfer transactions tx_31, tx_32, tx_33, tx_34 are polymerized to block chain transaction TX_3. Equipment 1 generate each block chain transaction in, separately include equipment 1 setting serial number seq and with each money transfer transactions Relevant information.

Serial number seq is related to the genesis sequence that each block chain is traded.Such as the seq value of block chain transaction TX_1 Seq value for 99, block chain transaction TX_2 is 100, the seq value of block chain transaction TX_3 is 101, shows that block chain is traded TX_1 is generated earlier than block chain transaction TX_2, block chain transaction TX_2 is generated earlier than block chain transaction TX_3.Correspondingly, block chain Node, can be according to the sequence of seq value from small to large successively to each area after receiving each block chain transaction of the submission of equipment 1 The transaction of block chain is handled, such as first processing block chain transaction TX_1, reprocessing block chain transaction TX_2, then processing block chain Trade TX_3.

Information relevant to each money transfer transactions may include: the initial state remaining sum of block chain transaction, the transaction of block chain End state remaining sum, the initial state remaining sum of each money transfer transactions, the turnovers of each money transfer transactions, each money transfer transactions End state (i.e. transitory state) remaining sum, proof information of each money transfer transactions etc..

By taking block chain trades TX_1 as an example.The initial state remaining sum of block chain transaction TX_1 is PC (100), block chain is traded TX_1 terminates that state remaining sum is PC (80), the initial state remaining sum of money transfer transactions tx_11 is PC (100), money transfer transactions tx_11 State remaining sum is the card of PC (110), money transfer transactions tx_11 to the end of turnover is PC (10), money transfer transactions tx_11 wait import Bright information includes that PC (10), PC (110) are belonging respectively to the section in correct value section and prove, money transfer transactions tx_12~tx_14's Related content can refer to Fig. 5, no longer enumerate herein.

It is noted that when in several money transfer transactions that mechanism 1 includes in block chain transaction as transferor or When relaying side, the account balance of itself corresponding block chain account Y1 can be subtracted corresponding transfer amounts by mechanism 1, and (transferor is only Produce fund；Relaying side not only can receive and be transferred to fund but also need to produce fund, be to be directed to the operation for the fund that produces and retouch here State), and subsequent money transfer transactions are continued to participate in based on updated money transfer amount.When block chain transaction is submitted to block chain Afterwards, if mechanism 1 is as transferor or a certain money transfer transactions successful execution of relaying side, mechanism 1 is without adjusting block chain account Y1；If mechanism 1 executes not successfully as a certain money transfer transactions of transferor or relaying side, mechanism 1 is needed to block chain account The account balance of Y1 carries out rollback adjusting.And it (is received when including mechanism 1 as beneficiary or relaying side in above-mentioned block chain transaction Money side is only transferred to fund；Relaying side not only can receive and be transferred to fund but also need to produce fund, be the operation for the fund that is transferred to here And describe) money transfer transactions when, if the money transfer transactions successful execution, mechanism 1 needs to increase into block chain account Y1 corresponding Fund realizes gathering, if money transfer transactions execute not successfully, mechanism 1 is without adjusting block chain account Y1.Correspondingly, block chain When the block chain received and processing equipment 1 is submitted is traded, the money transfer transactions that can include for block chain exchange are node It is no can successful execution, status indication is carried out to each money transfer transactions, for example transaction is success status, status of fail, overtime shape State etc..

Therefore, for above-mentioned " the initial state remaining sum of block chain transaction TX_1 is PC (100) ", equipment 1 is polymerizeing When generating block chain transaction TX_1, the remaining sum value of block chain account Y1 rising for block chain transaction TX_1 is not set as directly Beginning state remaining sum, but need first to determine to may cause the remittance of amount of money variation in block chain transaction that equipment 1 previously submitted Transaction, comprising: the amount of money that mechanism 1 generates when being marked as success status as the money transfer transactions of relaying side or beneficiary increases The gold that (gathering), mechanism 1 generate when being marked as status of fail or timeout mode as the money transfer transactions of transferor or relaying side Volume increases (transfer amounts progress rollback to having deducted) etc..And equipment 1 further takes according to the remaining sum of block chain account Y1 Value (deducted the transfer amounts for the money transfer transactions previously submitted, not yet collected money) is handed over the above-mentioned remittance that may cause amount of money variation The amount of money changing value easily actually generated, it is PC (100) that corresponding initial state remaining sum, which is calculated,；Equally, equipment 1 should be based on Each money transfer transactions that initial state remaining sum PC (100), respectively block chain transaction TX_1 include generate corresponding section card It is bright.

For another example Fig. 6 is a kind of showing for block chain transaction content based on plaintext numerical value that an exemplary embodiment provides It is intended to.As shown in Figure 6, it is assumed that equipment 1 chooses 4 money transfer transactions every time and is polymerized to a block chain transaction, for example remittance is handed over Easy tx_11, tx_12, tx_13, tx_14 are polymerized to the transaction of block chain TX_1, money transfer transactions tx_21, tx_22, tx_23, tx_ 24 are polymerized to block chain transaction TX_2, and money transfer transactions tx_31, tx_32, tx_33, tx_34 are polymerized to block chain transaction TX_ 3.In each block chain transaction that equipment 1 generates, separately includes the serial number seq of the setting of equipment 1 and handed over each remittance Easy relevant information.

Wherein, the effect of serial number seq is identical as embodiment illustrated in fig. 5, and details are not described herein again.With each money transfer transactions Relevant information may include: the initial state remaining sum of block chain transaction, the end state remaining sum of block chain transaction, each remittance The turnover of transaction；And due to using clear data, no longer need each remittance in embodiment illustrated in fig. 5 to hand over The permit of end state (i.e. transitory state) remaining sum of easy initial state remaining sum, each money transfer transactions, each money transfer transactions Contents, the block chain nodes such as breath are directly compared or calculate according to each plaintext numerical value.

Step 404b-c, equipment 2-3 according to the money transfer transactions in local queue 2-3, respectively polymerization generate transaction TX_b, TX_c, and it is committed to block chain respectively after signature.

In one embodiment, similar with equipment 1, equipment 2 can choose one or more remittances from local queue 2 Transaction generates corresponding block chain transaction with polymerization.It is assumed that equipment 2 includes above-mentioned remittance in the money transfer transactions that certain is once chosen Money transaction tx_i, and accordingly generated corresponding block chain transaction TX_b.

In one embodiment, similar with equipment 1, equipment 3 can choose one or more remittances from local queue 3 Transaction generates corresponding block chain transaction with polymerization.It is assumed that equipment 3 includes above-mentioned remittance in the money transfer transactions that certain is once chosen Money transaction tx_i, and accordingly generated corresponding block chain transaction TX_c.

Step 404d, for equipment 4 according to the money transfer transactions in local queue 4, polymerization generates transaction TX_d respectively, and is signing After be committed to block chain.

In one embodiment, similar with equipment 1, equipment 4 can choose one or more remittances from local queue 4 Transaction generates corresponding block chain transaction with polymerization.It is assumed that equipment 4 includes above-mentioned remittance in the money transfer transactions that certain is once chosen Money transaction tx_i, and accordingly generated corresponding block chain transaction TX_d.

It is noted that 1~equipment of equipment 4 can select to generate corresponding block chain transaction according to the actual situation, and Money transfer transactions tx_i might not be handled immediately；In other words, 1~equipment of equipment 4 is actually asynchronously to block chain Submit money transfer transactions tx_i (be contained in corresponding block chain transaction in) so that the execution of money transfer transactions tx_i be assigned to It is triggered respectively by 1~equipment of equipment 4, promotes 1~equipment of equipment 4 in the case where participating in a large amount of money transfer transactions, it can be right The money transfer transactions participated in carry out the transaction of Mass production block chain, to reduce the generation of block chain transaction and submit quantity, have Help reduce processing load, promote treatment effeciency.

Step 405, block chain node handles the block chain transaction received, includes to verify in the transaction of block chain Each money transfer transactions.

Step 406, money transfer transactions tx_i is marked.

In one embodiment, since each mechanism constantly can submit block chain to trade to block chain, and the area formerly submitted The money transfer transactions that Kuai Lian exchange includes will affect the money transfer transactions that the block chain exchange in rear submission includes, thus block Chain node needs to read include in received block chain transaction suitable after receiving the block chain transaction that each mechanism is submitted Sequence number seq, and the size of number seq in sequence successively handle the block chain transaction from corresponding mechanism.For example, working as area When block chain node receives the block chain transaction TX_a of the submission of equipment 1, reading serial number seq wherein included is 100；And such as The serial number seq of the processed nearest block chain transaction of fruit block chain node is 98, then block chain node needs The serial number seq submitted to equipment 1 trades for 99 block chain, and processed in the block chain transaction that the serial number is 99 Afterwards, the block chain transaction for being just 100 to said sequence number is handled.

In one embodiment, block chain node can be distinguished after receiving the block chain transaction that equipment 1~4 is submitted respectively The money transfer transactions for including in each block chain transaction are extracted, and implement individually verifying for each money transfer transactions respectively.Verifying behaviour Work may include: whether verifying signature is correct；" it may cause the remittance friendship of amount of money variation for above-mentioned in verifying money transfer transactions Whether correct, section proves whether correctly for the calculating of the amount of money changing value easily " actually generated；Fund transfer is produced volume and is transferred to Whether volume is consistent etc., no longer repeats one by one herein.

In one embodiment, other than the money transfer transactions for including in the transaction of each block chain individually implement verifying, such as The execution of fruit money transfer transactions simultaneously participates in triggering by participants such as transferor, relaying side, beneficiaries, thus block chain node also needs Whether each participant for verifying money transfer transactions, which all implements triggering, (has submitted the block chain comprising the money transfer transactions to hand over Easily).For example, Fig. 7 is a kind of schematic diagram for statistics triggering situation that an exemplary embodiment provides.As shown in fig. 7, being based on block Function is extended provided by the primary function of chain or intelligent contract, block chain node 1~mechanism of recording mechanism 4 can be mentioned respectively The block chain of friendship is traded, such as block chain transaction TX_a, TX_* that mechanism 1 is submitted, the block chain transaction TX_* of the submission of mechanism 2, TX_b, TX_#, block chain transaction TX_*, TX_c that mechanism 3 is submitted, block chain transaction TX_d that mechanism 4 is submitted etc.；And area Block chain node can extract the money transfer transactions for including in each block chain transaction, and be directed to the participation of each money transfer transactions respectively Side (in money transfer transactions details comprising transferor, relaying side, beneficiary information) counted: when receiving the submission of corresponding participant The transaction of block chain in include the money transfer transactions, can be by the participation and when the money transfer transactions have passed through above-mentioned independent verifying Side's label is OK ".

For example, including money transfer transactions tx_i in the block chain transaction TX_a submitted due to equipment 1, if block chain is traded Corresponding to the content of money transfer transactions tx_i by verifying in TX_a, then block chain node can mark and be "Y1:OK"；Similarly, if block chain node also respectively for 2~mechanism, mechanism 4 labeled as " Y2:OK ", " Y3:OK ", " Y4: OK " etc., then block chain node can determine that money transfer transactions tx_i has obtained the confirmation of all participants, it can be by the remittance Money trades tx_i labeled as success status.

It for another example, include the phase of money transfer transactions tx_* in the block chain transaction submitted due to only equipment 1, equipment 2 and equipment 3 Close information, even if thus these information all passed through and individually verified, block chain node still only can be the money transfer transactions Tx_* addition label " Y1:OK ", " Y2:OK ", " Y3:OK ", and need to continue waiting for the block chain transaction of the submission of equipment 4.

For another example, due to including the relevant information of money transfer transactions tx_# in the block chain transaction of the only submission of equipment 2, thus it is Just relevant information, which has passed through, individually verifies, block chain node still only can for the money transfer transactions tx_# addition label " Y2: OK ", and need to continue waiting for the block chain transaction that equipment 1, equipment 3 and equipment 4 are submitted.

Still by taking money transfer transactions tx_i as an example, if any participant in 1~mechanism, mechanism 4 has not been able to arrive at the transaction moment Up to submitting the block chain comprising money transfer transactions tx_i to trade before, then block chain node can mark money transfer transactions tx_i It for timeout mode, be successfully executed it can not.If although any participant in 1~mechanism, mechanism 4 is referred to comprising being somebody's turn to do The block chain of money transfer transactions tx_i is traded, but does not pass through list due to the amount of money adds up details error or section proves error etc. Solely verifying be successfully executed it can not then money transfer transactions tx_i can be labeled as status of fail by block chain node.

When money transfer transactions tx_i or other money transfer transactions are added to success status, status of fail or time-out by block chain node When state etc. marks, 1~mechanism, mechanism 4 can generate corresponding gold when being subsequently generated the transaction of block chain with reference to these states Volume adds up details, the section proof for generating remaining sum abundance etc., this and the above process phase described in step 404a~404d Similar, details are not described herein again.
