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 data modification method for block chain that the embodiment of the present invention one provides, and the present embodiment can
The case where suitable for modifying to the data block chain, can especially modify to Transaction Information.The block being applicable in
Chain can be publicly-owned chain, privately owned chain or alliance's chain.The scheme of the embodiment of the present invention is applied to block chain node, and this method can be with
It is executed by the data modifying apparatus or equipment of block chain, which can be used hardware and/or the mode of software is realized, and can collect
At in the electronic equipment of carrying block chain link point.Specifically comprise the following steps:
S101 obtains block data and modifies message.
Wherein, the modification message of block data can be the control instruction modified to block data, be also possible to send out
The transactions requests of the modification block data risen.It may include modification initiator information, modification time in block data modification message
And the contents such as data information of modification.
Optionally, in embodiments of the present invention, the mode for obtaining block data modification message has very much, and the present embodiment is to this
Without limiting.It can be the block data modification message that localized nodes receive the transmission of other nodes, wherein other nodes can be with
It is with super authority and the stronger central node of public credibility；It is also possible to an arbitrary node in block chain.Obtain block
Data modification message is also possible to localized nodes (i.e. localized nodes are the node for sending block data modification message) and directly acquires
Its own block data generated modifies message.
Optionally, the node for sending block data modification message is different, obtains the mode of block data modification message also not
Together.If the node for sending block data modification information is center node, obtaining block data modification message can be reception
The block data that central node is sent modifies message, specifically includes: receiving the block data modification message that central node is sent；It adopts
The super authority public key distributed with central node carries out central node authentication to block data modification order, and verifying is logical
Later receive the block data modification message.
Illustratively, after the block data modification message for receiving central node transmission, body first is carried out to central node
Part verifying, can just receive block data modification message after being verified, specific verification process can be, and central node can be with
Block data modification order is encrypted by super authority private key, then public key is distributed to section all in block chain
Point, localized nodes pass through the super power of central node transmission after receiving the block data modification message of central node transmission
The encrypted data are decrypted in limit public key, obtain the identity that data modification order carrys out authentication center node, if verifying
Pass through, block data modification message can be received.Block data is sent by central node and modifies message, block counts can be prevented
According to arbitrarily being modified or maliciously being distorted, the safety of block data is improved.
Optionally, if the node for sending block data modification information is any node, block data modification message is obtained
It can be and receive the block data modification message that any node is initiated with motion voting formula.It specifically includes: receiving any node
The block data of transmission modifies message, carries out motion voting, is confirmed whether repairing for executable block data jointly by all nodes
Change, when motion voting meets sets requirement, determines and receive block data modification message.
Illustratively, if any node can send block modification message, block data is maliciously usurped in order to prevent
Change, any node for sending block modification message can initiate block data modification based on common recognition mechanism in such a way that motion is decided by vote
Message.If the common recognition mechanism based on ballot ratio sends block data and modifies message, when localized nodes receive the block counts
When according to modification message, other nodes into block chain initiate the ballot notice of block data modification message, so that other nodes
It is voted, and counts voting results, based on the principle to use a large force to defeat a small one, receives block modification message if holding in voting results
Poll be greater than participate in ballot number of nodes setting ratio, it is determined that receive the block data modification message；If voting results
In hold support receive block modification message poll be less than or equal to participate in ballot number of nodes setting ratio, then refusal connect
Message is modified by the block data.Block data is initiated by any node and modifies message, can achieve the effect of decentralization, is led to
Motion voting formula is crossed to avoid the malicious modification to data, improves the safety of block data.
It is of course also possible to use other modes come control initiate block data modification message permission, can permit to obtain
The node of ad hoc fashion authorization initiates to modify.
Optionally, the block data modification message in the embodiment of the present invention carries in the intelligent contract of transactions requests.Example
Such as, if a certain code segment executed in intelligent contract is used to realize transactions requests (i.e. to the modification of Transaction Information in block),
Block generates node and is handled by the transactions requests to the code segment in intelligent contract, generates Transaction Information, is stored in
In block, so that subsequent other newly-generated nodes are all had the right, when, how backtracking is checked, to which node
Data are modified.It, can be with broadcast if block data, which modifies message, to be carried in the intelligent contract of transactions requests
Form the control instruction that block data is modified is sent to each block node so that its according to the control instruction execute pair
The modification of block data.
S102 modifies message according to block data, determines target modification block to be modified.
Optionally, it determines that the mode of target modification block to be modified has very much, which kind of mode area is specifically depended on using
The content for including in block data modification message.Specifically, if in block data modification message including the block of target modification block
Mark, it is determined that target modification block to be modified can be from block data modification message, extract target modification area
Block it is block-identified, using in block chain have the block-identified block as target modification block to be modified；If block counts
According to the block-identified of target modification block is not included in modification message, due to the modification of block data to be carried out, so wherein must
It surely include target transaction data to be modified, it is thus determined that can be when target modification block to be modified from the block counts
According in modification message, extracting target transaction data to be modified (can be specific Transaction Information, is also possible to the target transaction
The corresponding Transaction Information mark of data), the block including the target transaction data is searched, as the target modification block.
Wherein, target transaction data can be the Transaction Information to be modified in this block chain.It is extracted from block data modification message
After target transaction data to be modified, all blocks in block chain can be successively traversed, searching includes the target transaction number
According to block as target modification block.
S103 modifies message according to block data and modifies to the block data in target modification block.
Wherein, it is included at least in block data modification message: the target transaction data (area to be modified to be modified
Original transaction data in block) and for replacing the modification Transaction Information of target transaction data, or the original number of transactions of deletion
According to the instruction of content.
Illustratively, in embodiments of the present invention, message is modified to the block in target modification block according to block data
The process that data are modified may is that in target modification block with target transaction data content or target transaction Data Identification
It is searched, is modified after finding target transaction data to be modified to it, for example, it may be by new modification Transaction Information
Replace original target transaction data；It is also possible to according to modification Transaction Information to certain ginsengs in original target transaction data
Number is modified；Or it can directly delete.
S104, using the previous block of target modification block as starting block is reformed, to target modification block and thereafter
Transaction Information in continuous block is handled again, to generate new block chain, is connected to after reforming starting block.
Since modification has been carried out in the Transaction Information in the target modification block in block chain, in the target modification block
The Data Identifications of target transaction data to be modified just changed, so as to cause the root and mesh of the Mei Keer tree of generation
Mark modification the block-identified of block is all changed.Again because in each block head including the block mark of previous block
Know, therefore, the block-identified change of target modification block causes the block-identified of its latter linked all block and changes
Become, therefore, it is necessary to do all blocks after starting block using the previous block of target block as starting block, counterweight is reformed
In Transaction Information handle again, generate new block chain, be connected to reform starting block after.
Specifically, each Transaction Information in target modification block can be extracted since target modification block, it is based on Hash
Algorithm handles each Transaction Information again, generates the Data Identification of each Transaction Information, then regenerate based on Mei Keer tree algorithm
The root of Mei Keer tree is stored in the block head of new block, determine in block head other data (such as timestamp, random number,
Target Hash, mark of previous block etc.), to generate corresponding first new block of target modification block, then mention again
Take the Transaction Information in the latter block of target modification block, again processing generate the second new block be connected to the first new block it
Afterwards, and so on, the Transaction Information extracted in institute's block after reforming starting block in former block chain is all handled again,
A new block is generated for each original block and is joined together to form a new block chain, is connected to and is reformed sintering
After block.It is equivalent to, since the previous block of target modification block, has separately reformed a bifurcated block chain, and it is old
Block chain component is discarded.
Optionally, the Transaction Information in target modification block and its subsequent block is handled again, to generate newly
Block chain, be connected to the starting block of reforming includes: to generate node by current block later, executes and generates the new block
The operation of chain；Node is generated by current block, by the new block chain of generation, other nodes is transferred to and is stored.
It should be noted that the operation for executing the generation new block chain can be by one in the embodiment of the present invention
Current block generates node and completes, and is also possible to generate node by multiple and different blocks to complete, when reaching a certain switching
When condition, it is switched to next block and generates the processing again that node continues to execute Transaction Information, generate the behaviour of new block chain
Make.For example, if target modification block and its subsequent block there are 100 altogether, 11 blocks can be arranged to generate nodes, first 10
Block generates each generation and connection for being responsible for 10 new blocks of node, each block generate node complete 10 new blocks generate and
After connection, automatically switches to next block and generate generation and connection that node continues to execute subsequent new block, when 100 new blocks
After all generating, switches to the last one block generation node and deposited for newly-generated block chain to be transferred to other nodes
Storage.The new block chain of generation is transferred to other nodes and stored by the embodiment of the present invention, so that other nodes are to newly-generated
Block chain verified, avoid and there is the case where playing tricks when generating new block chain, improve the safety of block chain.
S105, the discarded subsequent block reformed after starting block.
Since S103 is modified the block data in target modification block, so that reforming starting in original block chain
The data in subsequent block after block are not correct, in order to avoid it is clashed between newly-generated block chain,
It needs to discard the subsequent block reformed in former block chain after originating block.Specifically, discarding the mode of subsequent block has very
It is more, for example, it may be subsequent block is deleted in former block chain, it can also be and set invalid for the block-identified of subsequent block
Mark, when view a certain block it is block-identified for it is invalid when, just default the block be invalid block.Due to reforming new block
Block-identified have occurred and that variation, each account or node, be according to new block-identified and things when searching block data
Business mark goes to obtain content.Old block-identified and old Transaction Identifier is not re-used as searching address, so also corresponding to old block quilt
It is discarded.
Optionally, when discarding the subsequent block after reforming starting block, not only local node will execute the operation, block
Other nodes in catenary system will also execute the discarded operation for reforming the subsequent block after starting block and optionally can be
Other nodes are notified to execute the operation of the S105 in the form of broadcast；It is also possible to carry the intelligence of the block data modification message
Energy contract, the discarded subsequent block reformed after starting block of instruction block chain node；It can also be that each node receives
After block data modifies message, and when having received newly-generated block chain, using public key, motion voting or other authorizations
Newly-generated block chain is verified, if being proved to be successful, the newly-generated block chain link is being reformed into starting block
Later, the subsequent block after starting block is reformed in automatic discarded former block chain.
The data modification method for present embodiments providing a kind of block chain modifies message by obtaining block data, to true
Data in fixed target modification block to be modified are modified, and using the previous block of target modification block as reforming
Originate block, the Transaction Information of subsequent all blocks is handled again, generates new block chain, be connected to reform starting block it
Afterwards, the subsequent block of original after reforming starting block is discarded.It is big to solve existing block chain technology modification Transaction Information difficulty
Problem can be realized the modification to block chain data, provide a kind of simple and effective solution for modification block chain data.
Embodiment two
Fig. 2 is a kind of flow chart of the data modification method of block chain provided by Embodiment 2 of the present invention, and this method is upper
State and further optimize on the basis of embodiment, provide a preferred embodiment, specifically, as shown in Fig. 2, this method comprises:
S201 obtains block data and modifies message.
S202 modifies message according to block data, determines target modification block to be modified.
S203 modifies message according to block data and modifies to the block data in target modification block.
The block data modified may be business association data, it is also possible to non-traffic associated data.Business association number
Data are shifted according to e.g. element, such as digital cash being transferred to or produces.Non-traffic associated data for example can be plain text
Data, image data etc..For business association data, after it is modified or deleted, may will affect in the block of subsequent zone
The processing of transactions requests.If the block data of modification exists with the transactions requests of subsequent block and conflicts, then asks in subsequent transaction
, will be different from former processing result when asking needs processed, or can not be processed.For example, if the block data of modification makes certain
The digital cash remaining sum of a account is zero, and subsequent transactions requests are to produce digital cash outward from the account.Since remaining sum is
Zero can not carry out producing processing, can accordingly notify user.
S204, using the previous block of target modification block as reforming starting block.
Optionally, when starting block is reformed in determination, if target modification block is one, by target modification block
Previous block is used as and reforms starting block；If target modification block is at least two, the mesh of block chain front end will be located at
The previous block of mark modification block, which is used as, reforms starting block.Because if the data in block are modified, from the area of modification
BOB(beginning of block), the Transaction Information in subsequent all blocks will be handled again generates new block, therefore, when there is multiple targets to repair
When changing block, without determining that is reformed a starting block according to each target modification block, it need to will only be in the target of front end
For the previous block of modification block as starting block is reformed, subsequent all blocks all handle number of transactions wherein included again
According to the new block chain of generation.
S205, for each block in block chain, extracts the original thing in block since target modification block one by one
Business request is handled, and forms Transaction Information, and be added in new block, repeats to handle again for each onblock executing, directly
It is disposed to subsequent block.
Illustratively, when being handled again the Transaction Information in target modification block and its subsequent block, for
Each block extracts original transaction data therein one by one, restores processing environment at that time, re-starts processing, forms thing
Business data, are added in new block, pass through the shapes Mei Keer trees such as hash algorithm, Mei Keer tree algorithm in the block body of new block
Root be stored in block head, determine and form a complete new block after other data in block head.From target modification area
BOB(beginning of block) executes each block thereafter one by one, a new block chain is formed, until subsequent all blocks have all been handled
Until finishing.
Optionally, if being to handle to obtain under a certain specific environment at that time from the original transaction reques extracted in block
Transaction Information, and handle the environment of the original transaction reques again and specific environment at that time is not inconsistent now, then it can be and pass through
Operating environment is handled at that time for simulation, or default directly acquires the number of transactions that the original transaction reques processing of former block is formed
According to.For example, simulation can be passed through if original transaction reques are the Transaction Informations formed in specific time-triggered protocol a certain at that time
The time environment of original transaction reques was handled at that time, is formed Transaction Information to handle the original transaction reques again, is added to new
In block；If original transaction reques are to execute in the environment of voting, and voted again at this time, possible outcome
It is different at that time, therefore, the Transaction Information that original transaction reques are formed in former block can be directly acquired at this time, be added to new
In block.
S206, by the new block chain link of generation and reform starting block after.
S207, the discarded subsequent block reformed after starting block.
The data modification method for present embodiments providing a kind of block chain repairs target according to block data modification message
Change after the data in block modify, for all blocks after starting block are reformed, extracts the original thing in block one by one
Business data re-start processing and form new block chain link after reforming starting block, discard after reforming starting block
Former subsequent block.It can realize to block chain data modification, the further perfect scheme of modification block chain data.
Embodiment three
Fig. 3 A-3C is the flow chart for the data modification method of block chain that the embodiment of the present invention three provides, the present embodiment with
Based on previous embodiment, a preferred embodiment is provided, suitable for when the data to block chain are modified, receiving in real time
The case where transactions requests of generation, if Fig. 3 A-3C is the flow chart of three kinds of processing methods in this case respectively.Next it combines
Fig. 3 A-3C specifically introduces following three kinds of processing methods.
Fig. 3 A is the first processing method provided in this embodiment, this method comprises:
S301 obtains block data and modifies message.
S302 after transactions requests processing, adds if receiving the transactions requests occurred in real time as Transaction Information
It is added in the block being presently processing.
Illustratively, the first processing method provided in this embodiment can also during to block chain data modification
The transactions requests are handled at once if receiving transactions requests with receiving the transactions requests occurred in real time, and will processing
As a result it is added to as Transaction Information in the block for being presently processing block chain data modification.
Optionally, if receive the transactions requests occurred in real time, it can be and continue S303-S306 after execution to block
Processing of the S302 to the transactions requests is executed while chain data modification, and obtained Transaction Information is added to and is currently being located
In the block of reason.For example, when handling the transactions requests occurred in real time, the modification and in real time for block data can be
The processing of the transactions requests of generation is arranged different blocks and generates node, and two nodes are performed simultaneously to the Transaction Information occurred in real time
Processing and block chain data modification operation.It is also possible to block and generates node to ask the affairs having executed S302
The processing asked, and obtained Transaction Information is added in the block being presently processing and then is continued to execute S303-S306
Modification to block chain data.For example, can be current block when handling the transactions requests occurred in real time and generate section
Point stops the processing to block chain data, first handles the real-time transactions requests that occur, Transaction Information is added to currently just
In the block of processing and then continue to execute modification to block chain data.
S303 modifies message according to block data, determines target modification block to be modified.
S304 modifies message according to block data and modifies to the block data in target modification block.
S305, using the previous block of target modification block as starting block is reformed, to target modification block and thereafter
Transaction Information in continuous block is handled again, to generate new block chain, is connected to after reforming starting block.
S306, the discarded subsequent block reformed after starting block.
It should be noted that the affairs that S302 reception occurs in real time in the first processing method described in the present embodiment are asked
It asks, Transaction Information is added to the specific execution sequence embodiment of the present invention of the process of block without limit after real-time perfoming processing
It is fixed, it can be executed parallel with S301, S303-S306 arbitrary process modified to block chain data.S302 is what specific when
It waits to execute and only depends on and when receive the transactions requests occurred in real time.
It should be noted that in the first processing method described in the present embodiment, to the data modification in block chain
In the process, the transactions requests occurred in real time are received, with regard to handling in real time the transactions requests, and by the Transaction Information of formation
It is added in the block being presently processing, if the Real-time Transaction data received are in business association data, with block chain
Data modification process is handled simultaneously, it is possible that the case where subsequent transaction data corruption, therefore the first processing method, it is more suitable
The case where Real-time Transaction request for receiving is non-traffic associated data, even if handling in real time transactions requests,
It will not influence the confusion of subsequent transaction data.Wherein, business association data, which can be, has incidence relation with subsequent transaction data
Data, include at least: account element shift data, for example, the transfer for the virtual objects being related between account.Non-traffic association
Data are then not have the independent data of incidence relation with subsequent transaction data, plain text data are included at least, for example, what user said
In short.
Fig. 3 B is second of processing method provided in this embodiment, this method comprises:
S307 obtains block data and modifies message.
If receiving the transactions requests occurred in real time buffer queue will be added after transactions requests processing in S308.
Wherein, buffer queue can be for temporarily storing at the transactions requests occurred in real time or store transaction request
The Transaction Information obtained after reason, the purpose that buffer queue is arranged are, avoid the transactions requests sent in real time and modification block chain
The case where original Transaction Information of block chain mixes, leads to data corruption in the process.For example, in modification block chain data
When, the original transaction data handled are middle A transfers accounts 50 bit coin to B, after the Real-time Transaction request processing at this moment received
The Transaction Information that obtains to be B transfer accounts 100 bit coin to C, if B is added to the transfer accounts Transaction Information of 100 bit coin of C at this time
A is transferred accounts to B after 50 bit coin, and real-time Transaction Information and historical transactions data are mixed, and is easy to cause the mixed of data
Disorderly.
Therefore, second of processing method provided in this embodiment can be when receiving the transactions requests occurred in real time
First the transactions requests are cached, are handled again after waiting original block to reform completion.The advantages of this arrangement are as follows that is,
Make to have received a plurality of transactions requests occurred in real time during to block chain data modification, caching team can be first stored in
In column, when follow-up storage, follows first in first out, is stored, will not be caused according to the chronological order of transactions requests
The confusion of data.
S309 modifies message according to block data, determines target modification block to be modified.
S310 modifies message according to block data and modifies to the block data in target modification block.
S311, using the previous block of target modification block as starting block is reformed, to target modification block and thereafter
Transaction Information in continuous block is handled again, to generate new block chain, is connected to after reforming starting block.
S312, the discarded subsequent block reformed after starting block.
Transaction Information in buffer queue is added in block by S313 after the completion of new block chain is reformed.
Illustratively, after the completion of the data modification of block chain, transactions requests progress can be extracted from buffer queue
Processing forms Transaction Information, Transaction Information is added in block.Alternatively, S308 to be added to the number of transactions in buffer queue
According to according to first in first out, being successively added in current block, to guarantee the accuracy of Transaction Information storage order.
It should be noted that second method occurs to real-time compared to the first processing method described in the present embodiment
Transactions requests receive after directly storage, but be first added in buffer queue, until block chain data modification is completed
Afterwards, then successively it handles.Can guarantee no matter real-time reception to transactions requests whether be business association data, not will cause thing
The confusion for data of being engaged in.
Fig. 3 C is the third processing method provided in this embodiment, this method comprises:
S314 obtains block data and modifies message.
Notice is submitted in S315, publication transactions requests pause.
Wherein, transactions requests pause submits notice to can be for notifying the node in block catenary system to suspend publication affairs
Request, it may include: distributor information, Dwell duration, pause reason etc. in notice that transactions requests pause, which is submitted,.The affairs
Request pause submits notice to can be a control instruction, is also possible to carry in the intelligent contract of transactions requests.
Optionally, publication transactions requests pause submit notice node can be with super authority and public credibility it is stronger
Central node, after the node in block chain, which receives affairs pause, submits notification message, using the super of central node distribution
Permission public key to transactions requests suspend submit notice carry out central node authentication, be verified be followed by it is temporary by the transactions requests
Stop submitting notice；Publication transactions requests pause submits the node of notice to can also be that any node initiates thing with motion voting formula
Notice is submitted in business request pause, after the node in block chain, which receives affairs pause, submits notification message, using voting
Mode come decide whether to receive the transactions requests pause submit notice；It can also decide whether to connect using other authorizations
Suspended by transactions requests and submit notice, the embodiment of the present invention is to specific method without limiting.
Illustratively, the node in block chain submits notice to transactions requests pause is received, and is verified, just no longer
Any transactions requests are submitted, until normally submitting notice until receiving transactions requests again.
S316 modifies message according to block data, determines target modification block to be modified.
S317 modifies message according to block data and modifies to the block data in target modification block.
S318, using the previous block of target modification block as starting block is reformed, to target modification block and thereafter
Transaction Information in continuous block is handled again, to generate new block chain, is connected to after reforming starting block.
