Embodiment one
Fig. 1 is the flow chart of the data processing method for the block chain that the embodiment of the present invention one provides, and the present embodiment is applicable Processing condition data in block chain network, such as be applicable in block chain network, some node is needed from other nodes The synchronous scene for obtaining block chain data.The block chain being applicable in can be publicly-owned chain, privately owned chain or alliance's chain.Overall procedure Cooperated by the promoter of synchronization group creation transactions requests in block chain with recipient and is executed to realize, the scheme of the embodiment of the present invention Applied to block chain node, node is generated by the node such as current block of reception synchronization group creation transactions requests and is executed.This method It can be executed by the data processing equipment of block chain, the mode which can be used software and/or hardware is realized, and can be integrated In the calculating equipment of carrying block chain link point.Referring to Fig. 1, this method is specifically included:
S110 receives the synchronization group that any node is initiated and creates transactions requests.
Wherein, wherein any node can be also possible to have setting to there is any node of synchronisation requirement in block chain The node of permission；It can also be that current block generates node etc..Synchronization group is made of one or more blocks；Synchronization group wound Build transactions requests and refer to transactions requests for creating synchronization group, be also possible to include synchronization group creation rule intelligent contract Deng.Optionally, may include: in synchronization group creation transactions requests includes the block-identified of block, synchronization group institute needed for synchronization group The information such as the mark of the signature scheme of the synchronous point position, synchronization group that need to be arranged or synchronization group.So-called synchronous point can generally refer to The end position of synchronization group, and the initial position of synchronization group can default setting, such as to default each synchronization group same from upper one Beans-and bullets shooter starts, or since the 0th block.
Illustratively, receiving the synchronization group creation transactions requests that any node is initiated may include: to receive any node reality The synchronization group of Shi Faqi creates transactions requests.Specifically, node of any node in block chain as block chain is added, Huo Zheyou Lead to block chain lack part or whole block nodes etc. in communication quality or by other factors such as malicious attacks, needs to synchronize Block chain, then locally generated synchronization group use demand, initiates synchronization group according to synchronization group use demand and creates transactions requests, and will Synchronization group creation transactions requests are transmitted in block chain network；Any node is initiated same in real time in localized nodes reception block chain Step group creates transactions requests.
In order to guarantee the security and reliability of block data, illustratively, the synchronization group creation that any node is initiated is received It can also include: that Authority Verification is carried out to initiation node after transactions requests；If Authority Verification passes through, receive synchronization group wound Transactions requests are built, otherwise refuses synchronization group and creates transactions requests.
Specifically, localized nodes, which can locally be safeguarded, has the section for initiating synchronization group creation permission in a block chain network The identity concordance list of point, after receiving synchronization group creation transactions requests, available synchronization group creation transactions requests The identity for initiating node, the identity for initiating node is searched in concordance list；If can find and correctly, It then determines that it is legal for initiating the identity of node, and initiate node there is the permission for initiating synchronization group creation, receives the initiation section The synchronization group that point is initiated creates transactions requests；If not finding or initiating the identity of identity and lookup of node simultaneously It does not complete to match, it is determined that initiate the permission that node does not initiate synchronization group creation, refusal synchronization group creates transactions requests.
It should be noted that can control to further control the permission for initiating synchronization group creation by setting The node of permission initiates the creation of synchronization group, such as is initiated by central node.Illustratively, permission is carried out to initiation node Verifying may include: to be verified using founder identity of the control authority public key to synchronization group creation transactions requests.Block chain In central node possess control authority, using control authority private key to synchronization group creation transactions requests partial content add Close, to show identity, therefore localized nodes can use control authority public key after getting synchronization group creation transactions requests The partial content that founder's identity is included at least in synchronization group creation transactions requests is decrypted.It is subsequent, it can will solve The verifying node that close obtained founder's identity is sent to setting is verified, or founder's identity mark that decryption is obtained Knowledge is matched with pre-stored identity to be verified.Wherein, each node in block chain can locally be safeguarded The table of each node identities mark of one storage.Identity can be node identification or network ip address etc..
It should be noted that the localized nodes in the present embodiment are that current block generates node.
S120 creates transactions requests according to synchronization group, determines at least one block, the synchronization block as synchronization group.
Wherein, synchronous block is the block for forming synchronization group.The synchronization block number of synchronization group can be one, can also be with It is multiple；If the block number of synchronization group is more than or equal to 2, the synchronization block in same synchronization group can be continuous block, It is also possible to discrete block.And the block between different synchronization groups can have it is overlapping.
Optionally, block-identified or synchronous point needed for the synchronization group for including in transactions requests being created according to synchronization group Etc. come the synchronization block that determines synchronization group.It is block-identified to refer to for the mark of a certain block of unique identification, it can be block ID or number etc., it is optionally, block-identified for block ID in the present embodiment；Synchronous point is referred to as insertion point, is used for table Show the position where first in synchronization group or end block；Optionally, the number of synchronous point can according to need and be arranged, such as One synchronous point can be only set at the block of synchronization group end；One can also be respectively provided at first block and end block Synchronous point.
S130 determines the synchronization signatures of synchronization group according to synchronous block.
Wherein, synchronization signatures refer to for unique identification or determine the mark of a certain synchronization group, can be used for representing synchronization The information etc. for the synchronization block for being included in group.Optionally, the synchronization signatures mode of synchronization group can be synchronization group creation affairs The signature scheme specified in request, is also possible to signature scheme as defined in block catenary system, can also be that localized nodes use certainly The signature scheme etc. that public key, private key or signature algorithm such as SHA256 of body etc. is determined.For the ease of subsequent query and verifying, and Increase the confidence level of synchronization signatures, illustratively, determines that the synchronization signatures of synchronization group can also include: basis according to synchronous block Synchronous block and the initiation node identification for initiating synchronization group creation, determine the synchronization signatures of synchronization group.Wherein, node mark is initiated Know the ID that can be the node for initiating synchronization group creation or network ip address etc..
Specifically, different signature schemes determines the verifying degree to block data, subsequent embodiment is by detailed Jie The different signature schemes that continue determine the implementation of the synchronization signatures of synchronization group.For example, can be according to synchronous block each in synchronization group Block-identified carry out hash signature obtain the synchronization signatures of the synchronization group.
It should be noted that the present embodiment determines the synchronization signatures of synchronization group according to synchronous block, show indirectly same The incidence relation between block, synchronization group and synchronization signatures three is walked, brings convenience for the subsequent group polling that synchronizes.
S140, using synchronization signatures as Transaction Information, record is within a block.
In order to reduce the probability that localized nodes distort the synchronization signatures of synchronization group, synchronization group is being determined according to synchronous block , can be using synchronization signatures as Transaction Information after synchronization signatures, storage is within a block.
Optionally, using synchronization signatures as Transaction Information, record may include: to generate to save by current block within a block Point is recorded in current block using synchronization signatures as Transaction Information；Current block is sent to other nodes to verify.
Specifically, localized nodes are determining synchronization group according to synchronous block if localized nodes are that current block generates node Synchronization signatures after, directly using the synchronization signatures of the synchronization group as Transaction Information, be recorded in current block；And it will be current Other nodes that block is sent in block chain are verified；After other nodes receive the current block of localized nodes transmission, Transactions requests will be created to synchronization group to handle, the synchronous label of the synchronization group are calculated using mode identical with localized nodes Name, if synchronization signatures are consistent with the synchronization signatures in current block, confirms that current block is effective, and current block is stored in In block chain；If inconsistent, other nodes into block chain send the block fail message comprising current block mark.
Using synchronization signatures as Transaction Information, after recording within a block, if any node wants synchronization zone in block chain Block chain can then verify synchronization signatures, after synchronization signatures are verified, be synchronized as unit of synchronization group, Accelerate data no-load speed.
Technical solution provided in an embodiment of the present invention, after receiving the synchronization group creation transactions requests that any node is initiated, Synchronization group is constructed according to synchronization group creation transactions requests, and the synchronization block according to composition synchronization group determines the synchronous label of synchronization group Name, is then stored in synchronization signatures as Transaction Information in block, reduces the probability that synchronization signatures are tampered.If block chain Middle any node is wanted to obtain block data, can be verified as unit of synchronization group, is the node verification area in block chain Block chain data provide a kind of new approaches, optimize the verification mode of block data.If the scene for synchronizing block data, Multiple synchronous blocks can be disposably verified, it is synchronous to accelerate data.Further, since any node in block chain, is needing Whens carrying out synchronous block data, verifying or inquiry etc. using synchronization group, synchronization group creation can be sent to block chain network in real time Transactions requests, localized nodes can receive the synchronization group creation transactions requests that any node is initiated in block chain, execute synchronization The creation operation of group, so that the creation of synchronization group can create in real time according to the actual situation, has flexibility.
Embodiment two
Fig. 2 is the flow chart of the data processing method of block chain provided by Embodiment 2 of the present invention, and the present embodiment is above-mentioned It is further to optimize on the basis of embodiment, present embodiments provide the indexed mode of synchronization group.Referring to fig. 2, this method is specific Include:
S210 receives the synchronization group that any node is initiated and creates transactions requests.
S220 creates transactions requests according to synchronization group, determines at least one block, the synchronization block as synchronization group.
S230 determines the synchronization signatures of synchronization group according to synchronous block.
S240, using synchronization signatures as Transaction Information, record is within a block.
The index data of synchronization group is stored in local synchronization group concordance list by S250.
Wherein, index data refers to the data that synchronous group information is quickly found for auxiliary node；It may include synchronizing Group mark, composition synchronization group it is each synchronize it is block-identified where block-identified, synchronization group synchronization signatures and synchronization signatures Deng.Synchronization group mark can be number or title of synchronization group etc.；It is block-identified to refer to for unique identification or determine a certain area The mark of block can be ID or number of block etc..
Synchronization group concordance list refers to the table that different synchronization group index datas are stored according to certain sequence or rule；For example, can To store the index data of different synchronization groups according to synchronization group mark, a synchronization group can be uniquely corresponding to synchronization group concordance list In a row or column etc..Optionally, synchronization group concordance list can carry out dynamically more according to the synchronization group established in block chain Newly such as increase, delete or replaces.
Specifically, localized nodes are receiving synchronization group creation transactions requests, and carry out signature processing verifying Transaction Information Afterwards, just the mapping relations of synchronization group, synchronization signatures and synchronous block etc. are stored in local synchronization group concordance list.
Illustratively, localized nodes can pass through any one or a few following side when needing to inquire a certain synchronization group Synchronization group needed for formula is inquired:
1) index data of synchronization group is inquired in local synchronization group concordance list.
2) request of synchronization group inquiry transaction is initiated, request current block generates node and traverses block chain from back to front to inquire Synchronization group；Wherein, synchronization group inquiry request refers to the request for inquiring synchronization group, may include required synchronization group mark or same Step group signature etc..
3) each node trusted to localized nodes sends synchronization group inquiry request, requests each node in the same of local Walk the index data etc. that synchronization group is inquired in group index table.
Specifically, localized nodes are when needing block chain synchronous using synchronization group, if synchronization group concordance list has been locally stored, Then can first it be inquired in local synchronization group concordance list, it, can be with if there is the synchronization group to match with required synchronization group The index data for directly acquiring the synchronization group synchronizes operation；If the synchronization group not matched, localized nodes can be to Its each node trusted initiates the request of synchronization group inquiry transaction, so that its each node trusted is receiving the synchronization After group polling transactions requests, the index data of synchronization group is inquired in local synchronization group concordance list；If localized nodes receive The each node feeding back trusted to it does not inquire information, then generates node to current block and send synchronization group inquiry transaction Request traverses block chain forward since current block to request current block to generate node to inquire synchronization group.If working as proparea Block generate node do not inquire matched synchronization group yet, then can initiate include required synchronization group synchronization group create affairs ask It asks.
It should be noted that can be independent progress between the mode of synchronization group needed for above-mentioned given inquiry；? Can according to first carry out local search, that is, first way, after carry out send synchronization group inquiry transaction request mode i.e. second or The third mode is inquired.
Technical solution provided in an embodiment of the present invention is stored in block in building synchronization group and by the synchronization signatures of synchronization group Afterwards, the index data of synchronization group can be stored in local in one synchronization group concordance list of local maintenance by the node in block chain Synchronization group concordance list in, provide convenience for subsequent query, verifying and synchrodata etc..
Embodiment three
Fig. 3 is the flow chart of the data processing method for the block chain that the embodiment of the present invention three provides, and the present embodiment is above-mentioned On the basis of embodiment, further the synchronization group creation transactions requests for receiving any node initiation are explained.Ginseng See Fig. 3, this method specifically includes:
S310 receives the synchronization group creation motion request that any node is initiated.
Wherein, motion request refers to that any node in block chain is needing to be implemented a certain affairs, such as when intelligent contract, Motion transactions requests are initiated, node is generated from current block and feeds back voting results to other node requirements；It can be in motion request Including at least one of following: the synchronization block of the synchronization group to be set up and signature scheme etc..Alternatively, motion request can be based on silent Recognizing mode indicates the creation content of synchronization group, for example, the synchronization group creation motion request currently initiated shows to create in current block Build synchronous point.
S320 is requested according to motion, initiates motion ballot notice, it is desirable that other nodes throw the creation of the synchronization group Ticket voting.
Specifically, localized nodes will initiate to vote after receiving the synchronization group creation motion request of any node initiation Notice, so that other nodes in block chain vote the creation of the synchronization group；Localized nodes receive other nodes The voting results of feedback, and voting results are summarized.
S330 receives the synchronization group in motion request according to voting results and creates intelligent contract, creates thing as synchronization group Business request.
It should be noted that synchronization group creation transactions requests are carried and are created in synchronization group as intelligent contract in the present embodiment It builds in motion request, obtains can store within a block after Transaction Information executing synchronization group creation transactions requests.
Specifically, localized nodes can according to ballot ratio-dependent voting results, ballot ratio can with default setting, or by Synchronization group creates motion request regulation.If voting results show that synchronization group to be created in motion request has enforceability, It then receives the synchronization group in motion request and creates intelligent contract, and the synchronization group is created into intelligent contract as a synchronization group and is created Build transactions requests；If it is against regulation etc. that voting results show in motion request synchronization group to be created, refuses motion and ask Synchronization group in asking creates intelligent contract.
S340 creates transactions requests according to synchronization group, determines at least one block, the synchronization block as synchronization group.
S350 determines the synchronization signatures of synchronization group according to synchronous block.
S360, using synchronization signatures as Transaction Information, record is within a block.
Technical solution provided in an embodiment of the present invention, localized nodes be based on intelligent contract to synchronization group creation motion request into Row voting, and the intelligent contract of synchronization group creation according to voting results to determine whether to receive in motion request is created as synchronization group Transactions requests are built, subsequent synchronization group visioning procedure is executed, further the quantity of creation synchronization group is controlled；Meanwhile It is stored in block chain, and then guaranteed after executing code segment and generating item data based on the transactions requests that intelligent contract is created Transaction Information is difficult to be tampered.
Example IV
Fig. 4 is the flow chart of the data processing method for the block chain that the embodiment of the present invention four provides, and the present embodiment is above-mentioned On the basis of embodiment, provide it is a kind of according to synchronization group create transactions requests, at least one block is determined, as synchronization group The mode of operation of synchronous block.Referring to fig. 4, this method specifically includes:
S410 receives the synchronization group that any node is initiated and creates transactions requests.
S420 creates transactions requests according to synchronization group, determines current block, the synchronization block as synchronization group.
It or the block that has generated, is newly generated in block chain network that current block, which refers to block chain network currently, Block.It should be noted that being then equivalent to synchronization signatures can be to a certain degree when a synchronization group includes a synchronous block It is to replace block-identified effect.Or it is set as the priority of synchronization signatures and is higher than the block-identified of synchronous block.The technical side Case provides more flexible selection space for the verification processing of block.
For example, due to including the block-identified of previous block in each block head data, and the block mark of a block Knowledge is determined according to signature etc. of Transaction Information, therefore the modification of a Transaction Information will lead to block-identified associated modification, It is i.e. subsequent all block-identified to will need to modify.In order to avoid associated modification, when localized nodes or other nodes need to modify When Transaction Information in a certain block, the synchronization group of block where including at least modification Transaction Information can establish.Preferably, may be used To establish the synchronization group for only including modification Transaction Information place block.
It should be noted that localized nodes default is using current block as the synchronization block of synchronization group.
Specifically, localized nodes can be created according to synchronization group current block block-identified for including in transactions requests or The mark etc. for the particular transaction data for including in current block, is inquired in block chain, if it exists and correctly, then will be current Block is determined as the synchronization block of synchronization group；If being not present in block-identified or incorrect, synchronization group creation can be considered as Transactions requests are invalid, and localized nodes will send the invalid information including synchronization group creation transactions requests to block catenary system.
Localized nodes can also create the synchronous point for including in transactions requests according to synchronization group, determine the corresponding area of synchronous point The block is determined as the synchronization block of synchronization group by block；It, can be in order to accurately obtain synchronization block corresponding to synchronization group Two synchronous points are set at current block position, and the end block determining according to two synchronous points and first block are same Block, then using current block as the synchronization block of synchronization group.
S430 determines the synchronization signatures of synchronization group according to synchronous block.
S440, using synchronization signatures as Transaction Information, record is within a block.
The technical solution of the embodiment of the present invention, due to synchronization group, only one synchronizes block, and localized nodes can be according to According to the block-identified synchronization signatures for determining synchronization group using simple signature algorithm of synchronous block, it is equivalent to using synchronization group label Name is instead of block-identified.Other subsequent nodes are needing the synchronization group to synchronize block chain, when being verified to the synchronization group, nothing Transaction Information in the synchronization block need to be handled one by one, need to only be calculated using signature algorithm identical with localized nodes synchronous Signature, and the signature for the synchronization group being calculated is matched with the synchronization signatures of synchronization group, simplifies verifying stream Journey accelerates verifying process.Meanwhile if the synchronization block of synchronization group is the block of modification, using the synchronization signatures side of synchronization group Formula can also avoid the occurrence of in existing block verification mode since the modification of Transaction Information causes by the synchronization block The block-identified the phenomenon that not being inconsistent stored in the block-identified and block that Transaction Information is handled one by one.It is signed due to synchronous Name is recorded in block, therefore has obtained the approval and effectively supervision of other nodes, therefore replace block in synchronization signatures When mark plays the role of verifying, can also play block data prevents from distorting.Further, since synchronization group is can be with Update, thus block can belonging multiple synchronization groups, all synchronization groups can not come into force simultaneously, such as with last The synchronization group of a creation is as the synchronization group that comes into force belonging to the block.
Embodiment five
Fig. 5 is the flow chart of the data processing method for the block chain that the embodiment of the present invention five provides, and the present embodiment is above-mentioned On the basis of embodiment, but provide it is a kind of according to synchronization group create transactions requests, at least two blocks are determined, as synchronization group Synchronization block mode of operation.Referring to Fig. 5, this method is specifically included:
S510 receives the synchronization group that any node is initiated and creates transactions requests.
S520 creates transactions requests according to synchronization group, determines current block and preamble at least one continuous block, makees For the synchronization block of synchronization group.
Wherein, continuous block is corresponding with discrete block.If any two area is not present at least two blocks Be between block it is discrete, then at least two blocks are continuous.
Specifically, the area that localized nodes can also include according to needed for the synchronization group for including in synchronization group creation transactions requests Synchronous point position being arranged needed for block identification or synchronization group etc. determines current block and preamble at least one continuous block Synchronization block as synchronization group.For example, can be created in transactions requests according to synchronization group includes synchronous point, synchronization group is determined End block will be determined as the synchronization block of synchronization group including the block between current block and end block.Localized nodes are also Include in transactions requests block-identified can be created according to synchronization group, navigates to a certain block, and by the area block Lian Zhongconggai Continuous block synchronization block etc. as synchronization group of the BOB(beginning of block) to current block.
It should be noted that position set by synchronous point is different, the synchronization group established is different；For example, current block For the 300th block, if synchronous point is arranged at the 200th block locations, the 200th block to the 300th block is one A synchronization group；If synchronous point is arranged at the 100th block locations, the 100th block to the 300th block is a synchronization Group etc..

1) transactions requests are created according to synchronization group, determines the block of at least two continuous m-n, the synchronization as synchronization group Block.
2) transactions requests are created according to synchronization group, determined since first block to the continuous block of current block, as The synchronization block of synchronization group.
It is continuous to update it should be noted that operation of the current block with block chain network, thus different synchronization groups it Between synchronization block it is overlapping.For example, current block is the 10th block, then in block chain the 0th block to the 10th block one A synchronization group；If current block becomes the 20th block, the 0th block to the 20th block is synchronization group etc..Example Property, if thering is new current block to generate in block chain, and after creating synchronization group according to new current block, block chain In the synchronization group that had previously been created can be defaulted as failing.For example, the 0th block of creation to the 20th block is a synchronization group Later, synchronization group failure that the 0th block to the 10th block is created etc..Synchronous point default setting is current in the present embodiment At block locations, and the end block as synchronization group, first block are defaulted as the 0th block.
Specifically, localized nodes can create the synchronous point position determination for including in transactions requests according to synchronization group works as proparea Block is the end block of synchronization group, and using the continuous block in block chain since 0 to current block as the synchronization of synchronization group Block.Localized nodes can also be block-identified according to include in synchronization group creation transactions requests, navigates to current block, and will Synchronization block in block chain since 0 to the continuous block of current block as synchronization group.If synchronization group creates transactions requests It is creation instruction, localized nodes are arranged one after getting synchronization group creation transactions requests directly at current block position A synchronous point, and the synchronization block etc. that will determine synchronization group to the continuous block synchronous point position since 0.
In the present embodiment, the synchronization group begun setting up from 0 is more suitable for the node being newly added in block catenary system and carries out together Walk block chain, it is only necessary to which the synchronization signatures for verifying a synchronization group do not need to test block each in synchronization group Card, simplifies verifying process.In order to avoid the setting of synchronous point is excessive, preferably using the 2) or the 3) in mode create together Step group.

It should be noted that directly being tested instead of synchronous the block-identified of block in the present embodiment using the verifying of synchronization signatures Function is demonstrate,proved, or is also possible to that verifying priority of the verifying priority higher than synchronous block of synchronization signatures is arranged.Using area Block number is primary according to being verified when synchronizing as unit of synchronization group, without one by one to the block-identified progress of each synchronous block Verifying, simplifies verifying process.Further, since synchronization signatures are recorded in block, therefore recognizing for other nodes is obtained It can be supervised with effective, while can also play the role of block data to prevent from distorting.
When node needs to download multiple synchronous blocks, such as whole block chain, then it may belong to continuous multiple synchronizations Group.Illustratively, it may include: that inquiry obtains block matched one to be synchronized that inquiry, which obtains the matched synchronization group of block to be synchronized, A or multiple synchronization groups.
Specifically, group polling can be synchronized according to the block-identified of required synchronization for including in block synchronization request, It obtains and the matched one or more synchronization groups of block to be synchronized.If only one synchronization group is matched with block to be synchronized, really The fixed synchronization group is required synchronization group；If existing simultaneously multiple synchronization groups to match with block to be synchronized, it is determined that multiple synchronizations Group is required synchronization group.If the synchronization group that some block to be synchronized is matched to has multiple, can be created according to each synchronization group The time built using the synchronization group of the last one creation as the synchronization group that comes into force belonging to block to be synchronized, and then guarantees to obtain every time The synchronization group taken is most newly created.
It in the above scheme, can also include: if it is determined that at least one block in block to be synchronized is without matched same Step group is then verified according to without matching the block-identified of block.For example, when block to be synchronized is 920 pieces, from front to back, often 100 pieces of compositions, one synchronization group, and last 20 pieces do not belong to any synchronization group, can be for belonging to the synchronization block of synchronization group It can be verified according to synchronization signatures, the block for being not belonging to synchronization group is verified according further to block self identification.
Technical solution provided in an embodiment of the present invention, localized nodes are only needed when needing to be synchronized using block data Verifying, nothing is compared with the synchronization signatures got from block in the synchronization signatures being calculated according to synchronous block Each the block-identified of synchronous block need to be verified one by one, compared with existing block data verification method, optimize area The verification mode of block number evidence simplifies verifying process, accelerates data synchronous.
