Specific embodiment

The present invention is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched The specific embodiment stated is used only for explaining the present invention rather than limiting the invention.It also should be noted that in order to just Only the parts related to the present invention are shown in description, attached drawing rather than entire infrastructure.

Embodiment one

Fig. 1 is a kind of flow chart of the random digit generation method for block chain that the embodiment of the present invention one provides, the present embodiment It is applicable to block chain node processing and needs the case where requesting using the business transaction of random number, wherein block chain node can be with It is the block generation node in block chain network；Other nodes being also possible in block chain network, it is such as raw currently without block At the arbitrary node of permission.

This method can be executed by the generating random number device or equipment of the block chain being configured in block chain node, should Hardware can be used in device and/or the mode of software is realized, and can be integrated in the electronic equipment of carrying block chain link point, this method Specifically comprise the following steps:

S101 obtains business transaction request, and is handled, and business transaction data are added to and are initiated in block.

Wherein, business transaction request is the transactions requests for needing just complete treatment process by random number, specifically may be used To be related to the business of any function.Business transaction request may include initiating transactions requests, can further include response Transactions requests.Initiation transactions requests can be the affairs that Business Initiator is generated based on business intelligence contract and initiation data and ask It asks, which can be the collection of programs for realizing the business, it can provide interactive interface in the business intelligence contract, The different content for initiating data and response data is provided for user, to generate each specific transactions requests.For example, if initiating Transactions requests are that transactions requests are initiated in guess, then the request can be guess initiator and be based on guessing intelligent contract and formulate this Secondary guess related data (e.g., the topic of guess, model answer, guess option, guess by the time, guess initiator information, Guess reward etc.) generate guess initiate transactions requests.Correspondingly, response transactions request, which can be service response side, is based on business The transactions requests that intelligent contract, the transactions requests to be responded (as initiated transactions requests) and response data generate.For example, if ringing Answer transactions requests for guess response transactions request, then the request can be guess responder and be based on guess intelligent contract, guess hair It plays the guess just sent and initiates transactions requests and response data (such as guess answer, guess response time and guess responder's letter Breath etc.) generate guess response transactions request.Optionally, business intelligence contract can also be respectively initiate, response formed it is different Intelligent contract separately includes the rule for how generating and initiating transactions requests, and how to generate the rule of response transactions request.

Business transaction data need to be added to the data stored in block after referring to processing business transactions requests, generally comprise The partial data of business transaction request itself and generation.The block of storage service Transaction Information, hair can be referred to by initiating block Playing block can be one, be also possible to continuous or discontinuous multiple.

Illustratively, after block chain node obtains business transaction request, i.e., business transaction request is handled, it can Choosing, which can be treatment process included before generating random number.Business transaction request is handled, is obtained To business transaction data, business transaction data are added to and initiate optionally, to can be the business transaction number that will be obtained in block According to be added to it is one or more initiate in blocks, the business transaction due to being related to a business request to have it is multiple, and by Different participants is initiated in different time, so business transaction data are likely stored in multiple and different initiation blocks.

Optionally, in the embodiment of the present invention, after business transaction data are added in initiation block by block chain node, also Initiation block added with business transaction data can be sent to block chain network.So that other nodes in block chain network To initiate block in data synchronize, verify or other operation.

S102, if business transaction request is needed using random number, in the generation period of result block, reception and industry The business associated seed transactions requests of transactions requests.

Wherein, as a result block is the subsequent block for initiating block, is the last one initiation if initiating block has multiple The subsequent block of block, with initiate block be different block, wherein the data stored be business transaction request, by random The final service processing result that number influences.The result block can be a block, be also possible to multiple blocks.As a result block Generating the period can refer to after business transaction data to be added to initiation block, and need according to random number process business thing Business request, obtains corresponding period when this service processing result.Optionally, as a result generation period of block, it can be hair Side is played before initiating business transaction request, by the height of result block or time (the 3rd day after such as initiating the request, or The 100th block etc. after initiating request) it is recorded in business transaction request；It is also possible to block chain node processing business affairs During request, determining according to the regulation of intelligent contract, for example, providing in intelligent contract, in preset time period, (such as 1 is small When) in be not received by and initiate the associated response transactions of transactions requests and request, it is determined that reach the knot of the initiation transactions requests Fruit block generates the period.

Seed transactions requests are provided by the business participant that business transaction is requested.The business participant of business transaction request It may include: that the initiator of the generation initiation transactions requests in business transaction request and/or at least one generation response transactions are asked The responder asked.The seed transactions requests that the business participant of business transaction request provides are according to seed text string generation.It can Choosing, for one's own profit, according to business development process, malice changes kind of a substring to business participant in order to prevent, from And directly interfere the generation of random number as a result, can be the Transaction Information for requiring business participant during obtaining business development Before, seed transactions requests are pre-generated.For example, being initiated when business participant is to generate the initiator for initiating transactions requests Side can generate seed transactions requests before generating initiation transactions requests, and be localized storage, and kind subtransaction is asked The Transaction Identifier asked is added in the initiation transactions requests of generation, subsequent to be just sent to block chain network.It is thus anti-well The subsequent development process according to business of business participant is stopped, malice changes asking for the kind substring in seed transactions requests Topic.

Optionally, if needed during handling business transaction request using random number, in the life of result block At in the period, receives and request associated seed transactions requests with business transaction, specifically, in the present embodiment, with business transaction Request associated seed transactions requests to include at least following several: 1) initiator in business participant send with initiate affairs Request associated seed transactions requests；2) what the responder in business participant sent requests associated seed thing with response transactions Business request.

Optionally, whether associated method is requested to have much with business transaction in the seed transactions requests that receive of judgement, To this present embodiment without limiting.For example, it may be determining the seed transactions requests by the seed transactions requests received Then it is compared, if unanimously, illustrating this step by corresponding Transaction Identifier with the Transaction Identifier in business transaction request In the seed transactions requests that receive and the business transaction obtained in S101 request be associated with；It can also be business participant and send seed When transactions requests, while the Transaction Identifier of the corresponding business transaction request of the seed transactions requests is also sent, at this time block chain link Point can pass through the affairs of the Transaction Identifier for judging to receive in this step and its business transaction received in S101 request It identifies whether unanimously, if unanimously, illustrating that the seed transactions requests received in this step are related to business transaction request.

Optionally, after determining that the business transaction request needs using random number, further includes: notice business transaction is asked The business participant asked provides seed transactions requests.It is corresponded to specifically, can be block chain node and generate business transaction request Seed obtain transactions requests be sent in block chain network, business participant node receive the seed obtain transactions requests Afterwards, by its it is pre-generated request associated seed transactions requests to be sent to block networking network with business transaction, block chain at this time Node can be in the generation period of result block, and receive the offer of business participant requests associated seed with business transaction Transactions requests.

It should be noted that business participant node sends the trigger condition of seed transactions requests not to block chain network Be defined in receive the transmission of block chain node seed obtain transactions requests after, just triggering offer seed transactions requests can be with It is business participant node when reaching preset condition, automatic trigger provides seed transactions requests, for example, it may be business participates in Square nodal test reaches business specified in business transaction request by the time or when needing to generate random number, and triggering provides kind Subtransaction request；It can also be business participant node in the industry for receiving the storage of the block chain network transmission participant node When the initiation block of the corresponding Transaction Information of transactions requests of being engaged in, i.e. triggering provides seed transactions requests etc..

Optionally, business participant does not send kind when block chain node needs to receive seed transactions requests in order to prevent Subtransaction request, or send mistake seed transactions requests the case where occur, block chain node can receive business When participating in sending business transaction request in direction block chain network, mortgage element is carried out to the account of business participant and is freezed, if When block chain node needs to receive seed transactions requests, it is not received by the kind of business participant transmission within a preset period of time Subtransaction request, or receive the seed transactions requests of mistake, then the mortgage element freezed is deducted from the account of business participant. The advantages of this arrangement are as follows being constrained the business participant for providing seed transactions requests, generating random number ring ensure that The confidence level in border.

S103 generates random number based on setting random algorithm according to the kind substring in seed transactions requests.

Wherein, character string needed for kind substring can be generation random number, this kind of substring can be by number And/or English alphabet is constituted.Setting random algorithm be it is preset, for generating the related algorithm or rule of random number.

Optionally, block chain node is after receiving and requesting associated seed transactions requests with business transaction, to the seed Transactions requests are handled, and wherein included kind of substring is obtained, according to the kind substring of acquisition, based on the random calculation of setting Method generate random number, specifically, can be by kind of substring according to setting random algorithm carry out related computing, generate with Machine number.Wherein, the random number of generation can be one, be also possible to multiple.

Optionally, in embodiments of the present invention, according to the kind substring in seed transactions requests, based on the random calculation of setting Method generates the process of random number, can also be and calls random number intelligence contract, according to the kind substring in seed transactions requests, Random number is generated based on setting random algorithm.Wherein, which can be due up how to generate random number Method and rule can be based on common recognition mechanism and set what random algorithm generated.Specifically, from seed transactions requests After obtaining kind of substring, the random number intelligence contract is called, the kind substring that will acquire is as random number intelligence contract Parameter；According to the parameter of the random number intelligence contract, random number intelligence contract is executed, this processing business transactions requests is obtained Required random number.

Optionally, in embodiments of the present invention, in order to improve generation random number safety, according to seed transactions requests In kind substring, based on setting random algorithm generate random number during, can also be call random number intelligence contract, According to the kind substring in seed transactions requests and the block-identified of block is initiated, is generated based on setting random number algorithm random Number.It can not be distorted due to initiating the block-identified of block, to ensure that the safety of generating random number.Optionally, should It is block-identified to can also be the block-identified of other blocks in addition to initiating block, to this embodiment of the present invention without limit It is fixed.

S104 generates service processing result according to random number and business transaction request, is added in result block.

Wherein, service processing result, which can be, requests the final process result obtained after handling to business transaction, should Processing result needs just to can be generated according to random number.

Optionally, after generating random number, according to the random number of generation, then S101 processes business transaction data Journey continues with business transaction request, obtains service processing result, and finally obtained service processing result is added to knot In fruit block.For example, if business transaction request initiates transactions requests for guess, according to the random number generated in S103, then S101 initiates the guess treatment process of transactions requests, continues with guess and initiates transactions requests, determines this guess result Obtained guess result is added to the guess and initiates affairs by (such as prize winner information, bonus distribution condition, prize-winning answer) It requests in corresponding result block.Optionally, it can be the service processing result that will be obtained to be added in current block, add at this time Current block added with service processing result is result block.

Optionally, the number of the random number generated in S103 in the embodiment of the present invention can be one, can also have multiple. When the random number of generation is multiple, when generating service processing result according to random number and business transaction request, can be makes Service processing result is generated with multiple random numbers.For example, if business transaction request initiates request for guess, when competing for this Guessing, the correctly guess responder that guesses is more multimodal, 3 random numbers can be generated, such as 1,5,8, at this point, correctly each for guessing Guess responder, is ranked up according to its time for sending guess response transactions request, the responder for the serial number 1 that sorts is arranged For the first prize, second prize is set by the responder for the serial number 5 and 15 that sorts, the responder for the serial number 8,18,28 that sorts is set It is set to third prize.

Optionally, in the embodiment of the present invention, after service processing result is added in result block by block chain node, also Result block added with service processing result can be sent to block chain network.So that other nodes in block chain network Data in result block are synchronized, verify or other operation.

It should be noted that requesting business transaction the process handled, including two portions in the embodiment of the present invention Point: first part S101 executes the relevant treatment operations participated in business transaction request without random number, obtains business transaction Data are added to the process initiated in block；Second part is S104, after generating random number, according to the random number pair of generation Business transaction request continues with, and generates service processing result, the process being added in result block.

It should be noted that the block chain node in the embodiment of the present invention, which can be block, generates node, it is also possible to remove Block generates other nodes other than node.It is to be introduced for block generates node that above-described embodiment, which is by block chain node, , if block chain node is other nodes, other nodes are also to execute the above process to generate random number, are completed raw to block It is verified at the Transaction Information that the request of node processing business transaction generates.Above-mentioned acquisition business thing is executed specifically, can be Business data, and handled, it is that the business transaction data initiated in block are carried out according to business transaction data after processing at this time Verifying receives the business transaction data initiated in block and is added in the block chain of the node if being verified；Execute it is above-mentioned such as It needs in the request of fruit business transaction using random number, is then generated in the period in block chain, received associated with business transaction request Seed request, according to seed request in kind substring, based on setting random algorithm generate random number；According to random number and Business transaction request generate service processing result, be at this time according to the service processing result of generation to the business in result block at Reason result is verified, if being verified, the service processing result in reception result block is added in the block chain of the node.

The random digit generation method of block chain provided in this embodiment needs to ask using the business transaction of random number in processing When asking, the seed character in seed transactions requests that the business participant node that block chain node is requested by business transaction is sent String generates random number, and then completes the processing operation of subsequent business transaction request.Solve centralization service organization generation with There are various unsafe problems for machine number, and provide kind of a substring by business participant, and block chain node is at the business of generation It is not know this kind of substring before reason result, so block chain node is constrained to fake；It is provided due to business participant Kind substring is pre-generated before block chain node processing business Transaction Information, provides seed word so also constraining The business participant for according with string cannot replace kind of a substring according to number one, improve the public letter for generating block chain random number Power improves the safety of random number.

Further, in embodiments of the present invention, according to the kind substring in the seed transactions requests, based on setting Before random algorithm generates random number, the seed transactions requests received can also be verified, it is specific: according to business thing The seed Transaction Identifier carried in business request, verifies the seed transactions requests.Wherein, business participant is generating industry When transactions requests of being engaged in, the Transaction Identifier of pre-generated seed transactions requests is carried in business transaction request, block chain link Point is after receiving business transaction request, so that it may uniquely determine the business transaction and request corresponding seed transactions requests Transaction Identifier, when block chain node is after receiving the seed transactions requests of business participant transmission, the kind that can will receive The seed Transaction Identifier carried in Transaction Identifier and business transaction request in subtransaction request is compared, thus to receiving The seed transactions requests of initiator are verified, if comparison result is consistent, are illustrated to be proved to be successful, can be continued to execute S103, According to the kind substring in the seed transactions requests received, random number process is generated based on setting random algorithm.It sets in this way Setting is advantageous in that, avoids the business participant of business transaction request for number one, according to the hair of business procession Exhibition, modifies pre-generated seed transactions requests and is sent to block chain node, with what is intervened the process for generating random number It happens, improves the random number safety and confidence level of generation.

Embodiment two

Fig. 2 is a kind of flow chart of the random digit generation method of block chain provided by Embodiment 2 of the present invention, this method with Based on previous embodiment, specifically gives when to receive and request associated seed transactions requests with business transaction and according to seed Kind substring in transactions requests generates the concrete condition introduction of random number based on setting random algorithm.As shown in Fig. 2, should Method includes:

S201 obtains business transaction request, and is handled, and business transaction data are added to and are initiated in block.

S202, if business transaction request is needed using random number, according to the block interval of business transaction request configuration Or the block interval configured according to preset rules, wait the block interval of setting quantity up to the generation period of result block.

Wherein, block interval can refer to the block height initiated between block and result block, such as can be and initiate area The quantity (M) for the block being spaced between block and result block is also possible to initiate specifically to be spaced between block and result block Time.The business participant that block interval can be initiation business transaction request is pre-configured in business transaction request, For example, being divided into 10 blocks between presetting block in business transaction request；It is also possible to block chain link point according to intelligent contract In preset rules configurations, for example, provided in intelligent contract, be divided between block initiate block to business the correspondence when the time Next block between interval.Setting quantity can be according to the determination of block interval, for example, if being divided into 1 area between block Block, then set quantity as 1, if being divided into 1 hour between block, set quantity as business transaction data are added to initiate block it Afterwards, in one hour, the quantity of the block generated including initiating block.Optionally, setting quantity can be at least one.

Illustratively, if business transaction request is needed using random number, first according to business transaction request in configure Block interval or the block interval configured according to preset rules, determine the setting quantity for needing to wait, and then wait setting quantity Block interval, the generation period until reaching result block, in the generation period of result block, just can receive business ginseng Associated seed transactions requests are requested with business transaction with what is just provided.

Optionally, it when setting quantity as one, can be after being added to business transaction data and initiating in block, It waits a block interval to reach result block and generates the period, is i.e. next block of initiation block is the generation for reaching result block Period illustrates that result block and the last one initiation block are adjacent blocks；If setting quantity as at least two, can be from It initiates block to count, waits at least two block intervals to reach result block and generate the period.

S203 is received in the generation period of result block and is requested associated seed transactions requests with business transaction.

S204 generates random number based on setting random algorithm according to the kind substring in seed transactions requests.

Optionally, if set quantity as one, according to the kind substring in seed transactions requests, based on setting with When machine algorithm generates random number, the block mark of block is can be according to the kind substring in seed transactions requests and initiated Know, random number is generated based on setting random algorithm；If set quantity as at least two, according to the kind in seed transactions requests Substring can be when generating random number based on setting random algorithm according to the kind substring in seed transactions requests, with And the centre block is block-identified, generates random number based on setting random algorithm；It is also possible to according to seed transactions requests In kind substring, initiate block block-identified and described centre block it is block-identified, based on setting random algorithm Generate random number.Specifically, according to kind of a substring, block-identified, based on the method that setting random number algorithm generates random number, Can be by kind of substring and it is block-identified according to setting random algorithm carry out related computing, generate random number；May be used also To be to call random number intelligence contract, according to kind of a substring, block-identified, random number is generated based on setting random number algorithm, It such as can be kind of a substring, the block-identified parameter as random number intelligence contract, execute random number intelligence contract, obtain This random number generated.

Optionally, centre block refers to that the block of generation can be with during waiting the block interval of setting quantity It is the block initiated between block and result block.The data stored in centre block may be associated with business transaction request Data when such as business transaction request to initiate transactions requests, can be the processing initiation with the associated data of transactions requests are initiated The response data that transactions requests associated response transactions generate when requesting；It is also likely to be to request unrelated data with business transaction, Other unrelated transactions requests, the Transaction Information of generation are requested with business transaction as handled.

If generating random number uses the block mark for being stored with the centre block for requesting associated data with business transaction Know, is then likely to occur the case where business participant that business transaction is requested carries out malicious interference to the generating process of random number.Example Such as, the guess responder A in guess participant, which is repeated several times, participates in a certain guess initiation transactions requests, then guess responder A The response data that the storage in centre block can be controlled all is that its own participates in the data responded when guess, due to block mark Knowledge be generated according to the data stored in block, so, at this time guess responder A can control to obtain the area of centre block Block identification, and then interfere the generation result of random number.In order to avoid such case appearance, it may be stipulated that: if setting quantity as extremely Few two, in initiating the centre block between block and result block, there need to be at least one centre block and be not present and industry (there is at least one centre block, the Transaction Information and business stored in the centre block in the associated data of transactions requests of being engaged in Transactions requests are unrelated).And according to the kind substring in seed transactions requests, random number is generated based on setting random algorithm When, can be according in seed transactions requests kind substring and at least one with business transaction request is not associated with completely Centre block it is block-identified, based on setting random algorithm generate random number.Specifically, can be from all centre blocks It is middle to obtain at least one and the completely not associated centre block of business transaction request, calculate the block-identified of the centre block, root According in seed transactions requests kind substring and at least one and business transaction request completely not associated centre block It is block-identified, random number is generated based on setting random algorithm.

In the present embodiment, it is not present there are at least one centre block and requests associated data with business transaction, it can be with Deliberately control, for example, it may be random number intelligence contract of the block chain node according to local disposition, recognize whether with Business transaction requests completely not associated centre block, and if it exists, then according to the kind substring in seed transactions requests, and At least one requests the block-identified of completely not associated centre block with business transaction, is generated based on setting random algorithm random Number.Optionally, at least one centre block is not present the phenomenon that requesting associated data with business transaction and is also possible to be natural shape At, without carrying out control deliberately, as soon as such as one may may be generated within 0.3 second quickly because generating the speed of a block Block, therefore in the associated response transactions request of processing business transactions requests, be not have when generating each block with Business transaction requests associated data to be acquired and store within a block, for example, if business transaction request initiates request for guess, The guess is initiated to announce answer after providing 1 day in request, within this 1 day time, produces hundreds of thousands block, but participates in Responder of this guess is unlikely to be guessing at every moment, it is impossible to each block in several ten thousand blocks In have guess answer.Or defined guess deadline to guess was announced between the time, interval is longer, that just necessarily has Centre block is not store data relevant to guess.

S205 generates service processing result according to random number and business transaction request, is added in result block.

The random digit generation method of block chain provided in an embodiment of the present invention needs the business thing using random number in processing When business request, after initiating block, wait the centre block of setting quantity up to the generation period of result block, then pass through industry The kind substring being engaged in the seed transactions requests that participant node is sent, and the middle area with business transaction request onrelevant Block it is block-identified, random number is generated based on setting random algorithm, and then complete the processing operation of subsequent business transaction request.It adopts With centre block, the block-identified generation random number of unrelated centre block is especially requested with business transaction, avoids business The case where participant malicious interference generating random number, further improve the safety of generating random number process.

Embodiment three

Fig. 3 be the embodiment of the present invention three provide a kind of block chain random digit generation method flow chart, this method with Based on previous embodiment, show in particular when business transaction request for initiate transactions requests when, how to execute block chain with The concrete condition introduction of machine number generation method.As shown in figure 3, this method comprises:

Embodiment five

Fig. 5 is a kind of signaling diagram of the random digit generation method for block chain that the embodiment of the present invention five provides；The present embodiment Based on foregoing embodiments, provide a kind of preferred embodiment, the preferred embodiment be block chain node and guess initiator and Guess responder interacts, and by the random number that itself is generated, and then completes the case where initiating guess transactions requests processing. As shown in figure 5, this method comprises:

S501, guess initiator generate seed transactions requests and are localized storage.

It should be noted that in the present embodiment, (such as block chain node, guess initiator's node and guess are rung each node Answer Fang Jiedian) portion of requiring affixes one's name to the intelligent contract of guess in advance, and the effect of guess initiator's node deployment guess intelligence contract is: Guess, which is generated, based on the guess intelligence contract initiates transactions requests.The effect of the block chain node deployment guess intelligence contract is: The processing that transactions requests are initiated in guess is carried out based on the guess intelligence contract.Guess responder's node deployment guess intelligence contract Effect be: based on the guess intelligence contract response guess initiate transactions requests, and then generate response guess transactions requests.

Optionally, it if guess initiator wants to initiate once to guess, needs first according to intelligent contract (guess intelligence of guessing In contract include seed transactions requests create-rule) regulation, one group of kind substring is randomly generated, such as " abc123 ", so Afterwards according to kind of a substring is generated, the guess intelligence contract is run, generates seed transactions requests, and the kind subtransaction of generation is asked The local for being stored in guess initiator is asked, the seed transactions requests that guess initiator generates are that the guess of its secondary initiation is corresponding Seed transactions requests, i.e. the guess of its secondary initiation initiates the corresponding seed transactions requests of transactions requests.

Illustratively, intelligent contract of guessing can be a user program client, can be by a main program and Multiple subprograms are constituted.When the initiator A that guesses wants to initiate guess, start the guess intelligence contract, into intelligent contract of guessing Interface inputs the kind substring " abc123 " that generates at random at the interface, at this time the guess intelligence contract will automatic running, And seed transactions requests are generated, and the seed transactions requests of generation are locally stored.

The Transaction Identifier of seed transactions requests is added to guess and initiated in transactions requests by S502, guess initiator, and to Block chain network sends guess and initiates transactions requests.

Optionally, in order to constrain the seed transactions requests that guess initiator distorts S501 generation, guess initiator needs root According to the seed transactions requests generated in S501, the Transaction Identifier of the seed transactions requests is calculated, is asked generating initiation affairs of guessing When asking, the Transaction Identifier of calculated seed transactions requests is added to the guess and is initiated in transactions requests.

Illustratively, guess initiator A can continue after generating seed transactions requests in intelligent contract circle of guessing Face, clicks Transaction Identifier and calculates key, guess at this time intelligent contract will automatic running, and generate the affairs of seed transactions requests Mark, then guess initiator A the interface input this guess topic, model answer, guess option, guess by when Between, guess initiator information, the information such as guess reward, click guess transactions requests and generate key, guess intelligent contract at this time just Meeting automatic running generates the guess comprising Transaction Identifier and initiates transactions requests.The initiator A that guesses can be incited somebody to action by its device end The guess of generation initiates request and is sent to block chain network, so that each node in block chain network is received and responded.

S503, block chain node receives guess and initiates transactions requests, and is handled, and the initiation data that will guess are added to It initiates in block.

Illustratively, block chain node receives guess and initiates after requesting, can be based on the guess intelligence disposed on its node Energy contract is initiated request to the guess and is handled, and obtains guess initiation data (such as the topic of guess, model answer, guess choosing Item, guess are by time, guess initiator information, guess reward etc.), it is added in current block, is added with guess at this time The current block for initiating data is to initiate block.

S504, guess responder generate seed transactions requests, are originally localized storage.

Optionally, if other nodes in block chain receive the guess transactions requests that guess initiator A is sent, if thinking This guess is participated in, which is exactly guess responder's node, optionally, transactions requests are initiated for a guess, It is corresponding guess responder number can be 0, one or more.The number of guess responder can be basis and actually want to Participate in the number determination of the node side of the guess.

Illustratively, by taking a guess responder as an example, when guess responder B desires to participate in what guess initiator A was sent When transactions requests are initiated in guess, the method that seed transactions requests can be generated using guess initiator A, to generate guess response The corresponding seed transactions requests of transactions requests, it is same not send first, and it is stored in local.

The Transaction Identifier of seed transactions requests is added in guess response transactions request by S505, guess responder, and to Block chain network sends guess response transactions request.

Optionally, equally, the seed transactions requests generated in S504 are distorted in order to constrain guess responder, guess responder It needs to calculate the Transaction Identifier of seed transactions requests according to the seed transactions requests generated in S504, is generating response thing of guessing When business request, the Transaction Identifier of calculated seed transactions requests is added in guess response transactions request.
