Applying example only is a part of the embodiment of the embodiment of the present invention, instead of all the embodiments.Based on the implementation in the embodiment of the present invention
The range of protection of the embodiment of the present invention all should belong in example, those of ordinary skill in the art's every other embodiment obtained.
Below with reference to attached drawing of the embodiment of the present invention the embodiment of the present invention will be further explained specific implementation.
Embodiment one
Referring to Fig.1, a kind of step flow chart of according to embodiments of the present invention one block generation method is shown.
The block generation method of the present embodiment is applied to alliance's block chain, this implementation different from traditional alliance's block chain
Alliance's block chain in example does not have host node, when generating new block, to reach data consistency, maintains alliance's block chain
Order, by the way of the verification of new district block number.
Specifically, the present embodiment block generation method the following steps are included:
Step S102: it receives the new block that the node in alliance's block chain is initiated and generates request.
Wherein, new block, which generates, carries the number of requested new block and the letter of corresponding block content in request
Breath.
Any node in alliance's block chain when needed, can issue new block and generate request, be generated with request new
Block.The new block generates request and broadcasts to the whole network, that is, all nodes into alliance's block chain include own node hair
The new block is given to generate request.
The present embodiment is illustrated block generation method, but ability from the angle of a node in alliance's block chain
Field technique personnel are it should be apparent that the node can be the arbitrary node in alliance's block chain, or it can be said that alliance's block
The processing that all nodes in chain generate request to new block all can refer to the embodiment of the present invention and realize.
The new block generates the volume that the i.e. described requested new block of number of block to be generated is carried in request
The information of number block content corresponding with new block.Each new block has a number, can determine this according to the number
Whether new block has generated, position and linking relationship in alliance's block chain etc., in practical applications, art technology
Personnel can use number that is any suitable, meeting block chain specification, unique identification block and can characterize it within a block
Position.And for the information of block content, those skilled in the art can also according to actual needs, using any appropriate
Mode realize, e.g., the summary info, etc. of the block content of new block, the embodiment of the present invention to this with no restriction.
Step S104: verifying the number of new block, in the corresponding block of number for verifying successful new block
The information of appearance is verified, and the pre-generatmg new block after verifying successfully.
It in this step, is verified by the number to new block, can both realize the verifying to the sequence of number, it can also be with
Prevent alliance's block chain bifurcated.When the number to new block verifies, can be deposited according to the number of new block with local
The relationship of number of newest block verified.After number verifies successfully, further, then the letter of block content is carried out
The verification of breath, to determine whether to meet the content requirement for generating block.
If number verification and content authentication are successful, can be with pre-generatmg new block.I.e. pre-generatmg is new after verifying successfully
Block can effectively promote the formation efficiency of new block, save new block and generate program.Wherein, the specific reality that new block generates
The generation and its specification for being now referred to block in Correlation block chain realize that details are not described herein.
Step S106: again verifying the number of new block, and the institute after verifying successfully into alliance's block chain
There is node to send confirmation message.
Because in block chain, what each node carried out generating at any time new block asks sum operation, to guarantee some
The accuracy that new block generates in this step, after pre-generatmg new block, again verifies the number of new block, to protect
It is still newest block to be generated that the block, which is demonstrate,proved, in processing stage.
After verifying successfully again, all nodes (including own node) of the present node into alliance's block chain send true
Recognize message, is prepared with indicating that this node has been carried out new block and generated.
Step S108: judging whether all nodes of alliance's block chain reach common understanding to confirmation message, if so, according to pre-
The new block of generation generates the new block for initiating the node that new block generates request.
Block chain solves asking in insincere channel reliable information as a kind of advanced distributed system
Topic.In block chain, since there are higher network delays under point to point network, so that thing of trading observed by each node
There is different in the sequencing of business (being specially that new block generates in the present embodiment), therefore a set of machine is also required in block chain
System, to reach common understanding within the regular hour to the sequencing that affairs occur, here it is common recognition mechanism.
Common recognition mechanism plays in block chain determines that who is responsible for generating new block and safeguards the unified effect of block chain, mesh
Preceding common recognition mechanism is based on Paxos evolution of algorithm.Paxos algorithm is a kind of consistency calculation based on Message-Passing Model
Method can ensure in a distributed data base system, if the original state of each node is consistent, each node executes phase
The same sequence of operation, then all nodes can finally obtain a consistent state.The common recognition mechanism of block chain substantially may be used at present
To be divided into PoW (proof of work), PoS (equity proves), PBFT (practical Byzantine failure tolerance algorithm) etc..
In this step, determine that all nodes have reached altogether the confirmation message in the common recognition mechanism by alliance's block chain
After knowledge, that is, new block is produced, specifically, the new block of pre-generatmg directly carries out new block and generates operation before can use.
Through this embodiment, host node is used, no longer in alliance's block chain to guarantee the area in no host node
Block normally generates, and has used number verification scheme, after receiving new block and generating request, i.e., to block (i.e. institute to be generated
State new block) number verified, to determine the sequence of block to be generated according to number, avoid block chain bifurcated；In turn,
After pre-generatmg new block, the number of block to be generated is verified again, to guarantee that the block is still in processing stage
Newest block to be generated.As a result, in the case where no host node, alliance's block chain it is also ensured that new block generation
Sequence and uniqueness, during also efficiently solving existing alliance's block chain generation new block, when generation host node failure
Or when host node election occurs, new block can not be generated, and then not can guarantee that reach data inside alliance's block chain consistent
The problem of property.
The block generation method of the present embodiment can be executed by any suitable electronic equipment with data-handling capacity,
Including but not limited to: server, mobile terminal (such as tablet computer, mobile phone) and PC machine etc..
Embodiment two
Referring to Fig. 2, a kind of step flow chart of according to embodiments of the present invention two block generation method is shown.
The present embodiment is illustrated block generation method provided in an embodiment of the present invention in the form of a specific example,
Similar with embodiment one, the block generation method of the present embodiment is also applied to alliance's block chain, uses in alliance's block chain
PBFT algorithm realizes common recognition mechanism, and alliance's block chain does not have host node.
It is similar with traditional PBFT, PBFT algorithm is also used in the present embodiment, and the generation of new block is logically divided into
Five stages are respectively as follows: the request stage, the pre-prepare stage, the prepare stage, the commit stage, execute simultaneously
The reply stage.
Based on the above scene, the block generation method of the present embodiment the following steps are included:
Step S202: it receives the new block that the node in alliance's block chain is initiated and generates request.
Wherein, new block, which generates, carries the number of requested new block and the letter of corresponding block content in request
Breath.
In a kind of feasible pattern, specific to each stage of PBFT, this step be may be implemented are as follows: generate processing in block
Second stage receives the new block that the node in alliance's block chain is initiated in the first stage and generates request and according to described new
Block generates the first state message that request generates；Wherein, first state message is used to indicate new block and is in first state, the
One state is used to indicate the state that new block is in the processing of pending pre-generatmg.By way of setting state and status message,
It can be consistent to greatest extent with PBFT algorithm, mitigate algorithm complexity, save new block manufacturing cost.Wherein, described
One stage was the request stage, and the first state is pre-prepare state, and the first state message is pre-
Prepare status message；The second stage is the pre-prepare stage.
It is integrated to the concrete application scene of the present embodiment, for example, some section in the request stage, in alliance's block chain
Point A initiates building new block Block request (i.e. new block generates request), and the state that the new block is arranged in node A is pre-
Prepare state (i.e. first state) broadcasts the status message (i.e. first state message) to the whole network.
And for other nodes in alliance's block chain, then the initial period in the pre-prepare stage receives the message, with
For one of node such as node B, node B, can the above-mentioned building new block initiated of receiving node A as other nodes
Block request, and the number of new block Block and the information of block content are carried in the request.It should be noted that above-mentioned
It describes by taking the other nodes for the node A for being different from issuing building new block Block request as an example, but those skilled in the art should
Clear, above-mentioned node B can be the arbitrary node in alliance's block chain, including node A itself.As it can be seen that in concrete application
In scene, this step betides the initial period in pre-prepare stage.
Step S204: new block is examined to generate whether request is repetitive requests；If so, to new block generation request into
Row processing；If it is not, thening follow the steps S206.
It is integrated to the concrete application scene of the present embodiment, for example, node B receives building new district in the pre-prepare stage
Whether block Block request, verification have received repetitive requests；If what is received is repetitive requests, refuse to handle the request；If not
Repetitive requests are new request, then are transferred to step S206 and are handled.As it can be seen that this step betides in concrete application scene
Intergrade after pre-prepare stage initial period.
Step S206: verifying the number of new block, in the corresponding block of number for verifying successful new block
The information of appearance is verified, and the pre-generatmg new block after verifying successfully.
In a kind of feasible pattern, this step be may be implemented are as follows: verification be numbered to the number of new block, if number school
Failure is tested, then request no longer is generated to new block and handled；If number verifies in the block for successfully verifying the new block
The information of appearance, and pre-generatmg new block no longer generate request to new block and handle if pre- life newly fails at block；If
The new block, then be added and prepare queue by the success of pre-generatmg block.It in this way, can be to avoid new block generating process
In fortuitous event cause block chain to fall into endless loop, and then entire block chain is caused abnormal or collapse occur.
Wherein, optionally, carrying out verification to the number of new block may include: to be traversed based on the corresponding hash value of new block
All vote informations of new block number verification failure if traversing result instruction new block has been voted；If the number of new block
Less than or equal to the number of current block, then verification failure is numbered；If the number of new block is greater than the number of current block, number
It verifies successfully.By the above-mentioned means, can effectively determine whether new block generates request effective.
The hash value (cryptographic Hash) of block chain can accurately and uniquely identify and identify a block, appointing in block chain
What node can obtain the cryptographic Hash of this block by simple Hash calculation.If the corresponding block of hash value was once
Ballot operation was carried out, then shows that the block had been established, request should not be handled again, number verification failure.
In block chain, block is serial number and generates, and current block is that successful newest block has been established,
Corresponding number is also newest number, if the number for the new block that request generates is also smaller than the number of current block or is equal to
The number of current block then illustrates that it should be the block (smaller than the number of current block) generated or the new block is raw
It is repetitive requests (equal to the number of current block) at request, number verification failure verifies successfully conversely, then numbering.
And it then can be by those skilled in the art according to actual needs, using any suitable to the verification of the information of block content
When mode realize, such as check code, redundancy check, etc., the embodiment of the present invention to this with no restriction.
It, then can be with pre-generatmg new block, wherein pre-generatmg after the information checking of number verification and block content is successful
New block specific implementation can by those skilled in the art referring in existing block chain new block generating mode realize, or
Person can also realize using other any appropriate ways, the embodiment of the present invention to this with no restriction.
Optionally, in addition, successful in the information checking of number verification and block content, and pre-generatmg new block it
Afterwards, namely after this step, the Block status of new block can also be set to the second state, and into alliance's block chain
All nodes send corresponding second status message, wherein the second state is used to indicate the new block and is in pending confirmation
The state of processing.It by way of setting state and status message, can be consistent to greatest extent with PBFT algorithm, mitigate and calculate
Method complexity saves new block manufacturing cost.
Specific to each stage of PBFT, this step be may be implemented are as follows: in the second stage to the number of the new block
It is verified, the information for the corresponding block content of number for verifying the successfully new block is verified, is being verified successfully
Pre-generatmg new block afterwards, and the second state is set by the Block status of the new block, the institute in Xiang Suoshu alliance block chain
There is node to send corresponding second status message, second state is used to indicate the new block and is in pending confirmation processing
State.Wherein, the second stage be the pre-prepare stage, second state be prepare state, described second
Status message is prepare status message.
It is integrated to the concrete application scene of the present embodiment, for example, node B is to request in the pre-prepare stage
The number of Block is verified；As current than having had already appeared and having authenticated the Block's in stage rearward in prepare stage
Verification failure is then numbered in the ballot of number, does not handle the building new block Block request of node A initiation；And if number verification at
Function then verifies the information of block content again, if information checking fails, the building new block Block for not handling node A initiation is asked
It asks, if information checking success, pre-generatmg new block；The building is not handled if the operation failure for executing pre-generatmg new block
If executing the operation success of pre-generatmg new block prepare team is added in the new block of pre-generatmg by new block Block request
Column, and it is prepare state (i.e. the second state) that new district bulk state, which is arranged, broadcasts status message (i.e. second state to the whole network
Message).As it can be seen that this step betided after pre-prepare intergrade in stage, it is believed that is in concrete application scene
The later period in pre-prepare stage.
It should be noted that above-mentioned with according to block, whether there is or not vote informations to verify to be numbered but as previously mentioned, unlimited
It, can be with when numbering verification in this kind of number verification mode: 1, all vote informations of new block state phase are traversed, if packet
The corresponding block of the value of hash containing new block has been voted, then numbers verification failure；2, if block number to be voted is less than or waits
In the number of current block, then verification failure is numbered；3, if block number to be voted is greater than the number of current block, number
It verifies successfully.It is verified by number, block chain bifurcated can be effectively prevented, realized the sequence verifying of block number, guarantee new district
The correctness and validity that block generates.
Step S208: again verifying the number of new block, and the institute after verifying successfully into alliance's block chain
There is node to send confirmation message.
Wherein, the mode verified again to the number of new block is identical with step S206, and details are not described herein.
In specific implementation, can the number again to the new block verification is numbered, if number verification failure,
No longer request is generated to the new block to handle；And if number verifies successfully, all nodes into alliance's block chain
It sends and submits message, to guarantee the validity and robustness of alliance's block chain.
In a kind of feasible pattern, all nodes after verifying successfully into alliance's block chain send confirmation message
It include: to set the third state for the Block status of the new block after verifying successfully, and by corresponding third state message
As confirmation message, all nodes into alliance's block chain are sent, wherein the third state is used to indicate the new block and is in
The pending state for submitting processing.By way of setting state and status message, it can be kept to greatest extent with PBFT algorithm
Unanimously, mitigate algorithm complexity, save new block manufacturing cost.
Specific to each stage of PBFT, this step be may be implemented are as follows: generate the phase III of processing again in the block
The number of the new block is verified, and after verifying successfully, sets third shape for the Block status of the new block
State, and using corresponding third state message as confirmation message, all nodes in Xiang Suoshu alliance block chain are sent, wherein
The third state is used to indicate the new block and is in the pending state for submitting processing.Wherein, the phase III is
Prepare stage, the third state are commit state, and the third state message is commit status message.
It is integrated to the concrete application scene of the present embodiment, for example, node B is again to the volume of Block in the prepare stage
Number verification is numbered；If number verification is unsuccessful, the building new block Block request is not handled；If number verification at
Function, then it is commit state (i.e. the third state) that Block state, which is arranged, and broadcasts status message (the i.e. third state to the whole network
Message).As it can be seen that this step betides the prepare stage in concrete application scene.
Step S210: judging whether all nodes of alliance's block chain reach common understanding to confirmation message, if so, according to pre-
The new block of generation generates the new block for initiating the node that new block generates request；If it is not, then being handled without new block generation.
In block chain, responded when all nodes generate request to new block, such as feeding back confirmation message, then it is assumed that
All nodes have reached common recognition.For each node in block chain, confirmation message (wraps all nodes into block chain
Include own node) it sends.
For present node, can by judging whether to receive the confirmation messages of all nodes in alliance's block chain,
To determine whether that all nodes in alliance's block chain have reached common recognition.
It is when the confirmation message is to submit status message, then described to judge all sections in a kind of feasible pattern
It may include: to judge whether to receive mentioning for all nodes in alliance's block chain that whether point, which reaches common understanding to the confirmation message,
Hand over status message；If so, determining that all nodes are reached common understanding；Otherwise, it is determined that do not reach common understanding.
And when generating the new block for initiating the node that the new block generates request according to the new block of pre-generatmg,
It can then verify whether present node had locally generated the new block；If so, not regenerating；If it is not, then from pre-generatmg
The new block in obtain metadata information and content-data, alliance's block chain is written into the metadata information, and at this
Ground saves the content-data.
Optionally, in addition, the node initiated the new block and generate request is being generated according to the new block of pre-generatmg
New block when, the Block status of the new block can also be set to the 4th state, and according to the 4th state and pre-generatmg
New block, generate the new block for initiating the node that the new block generates request, wherein the 4th state is used to indicate described new
Block is in the state for having been carried out and submitting processing.Setting state and status message by way of, can to greatest extent with
PBFT algorithm is consistent, and mitigates algorithm complexity, saves new block manufacturing cost.
Specific to each stage of PBFT, this step be may be implemented are as follows: generate the fourth stage judgement of processing in the block
Whether all nodes reach common understanding to the confirmation message, if so, setting for the Block status of the new block
Four states, and according to the new block of the 4th state and pre-generatmg, it generates and initiates the section that the new block generates request
The new block of point, and the information of the new block generated to all nodes transmissions, wherein the 4th state is for referring to
Show that the new block is in the state for having been carried out and submitting processing；In the 5th stage of block generation processing, described in reception
The information of new block, and according to the information of the new block, it is verified to locally the new block whether had been generated, according to
Check results carry out the processing that the new block generates request.Wherein, the fourth stage is commit stage, the 4th shape
State be committed state, the 4th status message be committed status message, the 5th stage be execute and
The reply stage.
It is integrated to the concrete application scene of the present embodiment, for example, each node receives commit state in the commit stage
It carries out counting after message accumulative；Because PBFT algorithm maximum can tolerate that the node of one third is problematic, that is, PBFT needs at least
The confirmation message of 2/3rds node is to reach common understanding, and therefore, if each node is received, more than 2f+1, (wherein, f indicates institute
Having a number of trouble node in node, 0≤f≤(N-1)/3, N is the quantity of all nodes) a different nodes (include itself
Node) commit status message after, it is believed that the processing of the new block the whole network (i.e. all nodes of alliance's block chain)
Reach an agreement, into committed state (i.e. the 4th state), alliance's block chain be written into the metadata information of the new block,
And the full content of the new block is stored in the local relevant database such as local, in sqlite database.
