It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure
Completely it is communicated to those skilled in the art.
Block chain is proposed along with the generation of bit coin, therefore, in the data that description block chain is related to
In, use transaction data and the such expression of account book, with the development of block chain technology, the information and data that are able to record
It has been not limited to traditional transaction data, and can be used to record any information and data.Therefore, implement in invention
In example, transaction data refers to an information, data or instruction etc., and account book refers to the set being made of multiple transaction data
Body.
Block chain refers to the data store organisation after block chain technology secrecy being made of multiple blocks, block link network
Network refers to the network for having multiple nodes for realizing block chain technology to constitute.Node in block chain network can be in internet
Server or terminal device with processing block chain data function.Each node in block chain is executed to transaction data
Kept accounts be linked on existing block chain (by transaction data write area block), by new block, to block chain carry out storage and
The functions such as verification.
The basic principle of the embodiment of the present invention is：By referring to comprising the transaction data for closing existing block in block chain
Show that node establishes backward chaining, the opportunity for establishing backward chaining is after new block generation.Mode is established in backward chaining, is exactly
In existing block before the data of this new block are written to through the check value that non-reversible algorithm is calculated, to establish
One is played from the new block to the backward chaining of existing block.During the foundation of new block, node can obtain transaction in advance
Data, in embodiments of the present invention, including can be a kind of finger for having the transaction data of block in feedback control block chain
The form of order, the node in block chain can recognize that the processing indicated in the transaction data when getting the transaction data
It is to establish backward chaining, to which after generating new block, the processing of backward chaining is established with regard to triggering.
It should be noted that in the embodiment of the present invention, the link between block is the link on a kind of logical meaning, this
Linking relationship is embodied by the authentication mechanism in block chain.In traditional block chain, in the block head of latter block
The check value generated based on previous block is record, and is constantly extended forward based on such mechanism, to form side of link
To forward block chain always.
As shown in Fig. 2, comprising the backward chaining for being directed toward block 3 by block 4 in the block chain, i.e., in the block head of block 3
The check value hash2 for including block 4 causes the content of block 3 to be changed due to the foundation of backward chaining, when using in block 4
The check value of record when being verified to block 3, due to there is Hash2 in the block head of block 3, be based on modified area
Block 3 calculates the check value obtained not equal to the check value recorded in the block head of block 4, to authentication error occur.
Pass through this authentication mechanism, so that it may to identify the presence of backward chaining.It in practical applications, can be in each area
The data area for filling in reversed check value is reserved in the block head of block, thus during subsequent authentication, when discovery should
There are when data in region, it will be able to knowing the block, there are backward chainings, then again based on the data to the block after
Each block is verified, and is found and which block to be calculated the check value obtained based on, so that it may to know complete backward chaining
Relationship.
For identifying backward chaining, it can also be realized by way of block chain errata.Block chain errata
The supplement that can not distort mechanism to block chain is may be considered, which can be by management block chain network
Supervisory node safeguard that, it is intended that for executing some necessary modifications to block chain, these modifications are to supervise
It is completed under the monitoring of node, to ensure the accuracy of block chain data.
Modification to each block in block chain can be recorded in block chain errata corresponding with block chain,
Record the specific location (line number and row number of data in block number and block where modification in the block chain errata
Deng), and information or data before and after modification.During verification, if there is verification not by situation, Ke Yicha
Ask the errata, determine the verification not by block with the presence or absence of modification, if it is present can use modification before data
Or information is verified again, if passed through, can be confirmed that the modification by what is allowed, is not maliciously tampered.Also,
It in the block chain errata, can also further record, whether which is the modification of backward chaining, and is specifically which is based on
The information such as the check value that a block generates, consequently facilitating identifying the logical relation of backward chaining.
The technical solution of the application is further illustrated below by multiple embodiments.
Embodiment one
Based on the scheme thought that backward chaining structure in above-mentioned block chain and corresponding data are handled, as shown in figure 3, it is this
The executive agent of the feedback method for treating flow chart in block chain shown in inventive embodiments, this method can be in block chain
Handle node.As shown in figure 3, the feedback method for treating in the block chain includes：
S310, in response to including the life for carrying out the new block of feedback control to having the transaction data of block in block chain
At check value is calculated through non-reversible algorithm to new district data in the block.
The check value of new block is written in existing block by S320, is formed from new block and is directed toward the reversed of existing block
Link；To identify new block to having the Feedback control logic of transaction data in block.
During block chain extends and generates new block, if be stored in current new block for have block into
The transaction data of row feedback control calculates new district data in the block through non-reversible algorithm then after generating the new block
To check value, and the check value of the new block is written to this and is had in block, to form backward chaining.The backward chaining is used
It is showed and numbers different before by new district transaction data feedback control in the block with identifying transaction data in existing block
According to form.
Wherein, above-mentioned non-reversible algorithm can be hash algorithm, and corresponding check value is cryptographic Hash.
Here in the so-called chain to block have block transaction data carry out feedback control can include but is not limited to as
Lower control operation：
1. opening the transaction data for having block in block chain
Here so-called transaction data is effective by the i.e. finger transaction data of unlatching, subsequently can be based on the number of deals that these are opened
According to the new corresponding new block of transaction data of generation.
For example, the scheme thought based on backward chaining structure in above-mentioned block chain, can form the two-way block as shown in 4
Chain structure schematic diagram, including：At least one Two-way Chain (Two-way Chain being made of Block2 and Block4 in such as Fig. 4)；
The Two-way Chain is by a first block (such as Block2) and one in rear block (such as Block4) along two phase negative sides
It is formed after being linked to sequence, and is formerly stored with the verification being calculated through non-reversible algorithm in back zone data in the block in block
Value.For example, the non-reversible algorithm can be hash algorithm, corresponding check value is cryptographic Hash.
Wherein, so-called one first block and one refer to the areas Xian An along two opposite directions sequence links in rear block
The direction that block chain normally extends from front to back is first extended based on the first block as father's block and is generated as sub-block rear
Then block re-forms the backward chaining that first block is directed toward in rear block, the Block2 that is so formed in similar Fig. 4 and
The chain with bi-directional chaining that Block4 is constituted.
Although theoretically the two blocks father, sub-block each other, should all be stored in the block head of the two blocks pair
Check value that square area's data in the block are obtained through non-reversible algorithm and seem contradiction, still, since the link in the two directions is
Logic will not be caused to obscure through what sequencing generated, i.e., it, first can not by the data warp in Block2 when generating Block4
Algorithm for inversion obtains check value, and the check value is recorded in the block head of Block4, then again by include Block2 school
All data tested in the Block4 of value obtain check value through non-reversible algorithm, and the check value is recorded in the block of Block2
In head.In other words, the check value of former father's block had both been stored in Block2, while the verification of sub-block Block4 is also stored
Value.
In fact, two-way chain structure can be considered as two adjacent blocks, first link is formed along the direction normally extended
The direction of Block2 → Block4 (link), then link along being formed in the opposite direction with the side normally extended (Block4 →
The direction of Block2 links) it is constituted afterwards.
When based on forming backward chaining, need to the areas Liang Ge the repairing in preceding block in the block with backward chaining relationship
Change, so as to cause verification can not by logic, can set should proparea transaction data in the block formed when as closing
State (i.e. transaction data is unavailable) is after forming backward chaining, and transaction data is just arranged, and by unlatching, (i.e. transaction data can
With).Based on the logical relation that this data are opened, in the Two-way Chain of formation can also to the logical relation of above-mentioned unlatching into
Row is expanded.For example, in setting Two-way Chain after first area transaction data in the block is opened, link with the first block other
Area's transaction data in the block also opened by synchronization.
For example, in the process field of assets, it is understood that there may be following demand：A collection of money is sold in some designated blocks concentration
Production, but the assets are initially invalid state, and after meeting certain condition, a special friendship is executed in a block later
Easily, the assets of designated blocks before are all started.Above-mentioned condition can be by the regular hour, for example, for some
The commodity of quality inspection phase are still in, after quality inspection passes through, which just has the value of sale.In addition, above-mentioned condition can also
That the forms of assets variation (be initialized as invalid) occurs, when such a change occurs it is necessary to by special transaction data come
It triggers the assets and enters effective status.
For this situation, so that it may to establish a backward chaining by a special deal data-triggered, and then by it
Transaction data in preceding designated blocks carries out unlatching processing, so that the assets of block from becoming effective shape in vain before
State.
Has the transaction data of block 2. closing in block chain
Here so-called transaction data is closed that refer to transaction data invalid, can not subsequently be based on these pent friendships again
Easy data generate the corresponding new block of new transaction data.
For example, the scheme thought based on backward chaining structure in above-mentioned block chain, can form annular block as depicted in fig. 5
Chain structure schematic diagram, including：
At least one endless chain (endless chain being made of block Block2, Block4 and Block5 in such as Fig. 5)；
The endless chain is formed by multiple blocks after same circular direction sequence link, and the head end block of endless chain is (such as
Block2 the verification that the data being stored in) in the end block (such as Block5) of endless chain are calculated through non-reversible algorithm
Value.For example, the non-reversible algorithm can be hash algorithm, corresponding check value is cryptographic Hash.
In fact, annular chain structure can be considered as a block chain part normally to extend (Block2 → Block4 →
The block chain part of Block5) and one rear block be directed toward preceding block backward chaining block chain part (Block5 →
The block chain part of Block2) it is constituted.
When based on forming backward chaining, need to the areas Liang Ge the repairing in preceding block in the block with backward chaining relationship
Change, so as to cause verification can not by logic, it is possible to determine that should in proparea data invalid in the block, i.e. transaction data is closed
It closes.Based on the pent logical relation of this data, in the endless chain of formation can also to the logical relation of above-mentioned closing into
Row is expanded.For example, only head end area transaction data in the block is closed in setting endless chain, or all areas in setting endless chain
Transaction data in the block is closed, or when going back chain in endless chain and being connected to other blocks, these other areas transaction in the block
Data are also synchronized and are closed.
For example, in the process field of assets, it is understood that there may be following demand：A collection of money is sold in some designated blocks concentration
Production executes a special transaction, the assets of designated blocks before after meeting certain condition in a block later
All cancel.Above-mentioned condition can, for example, for some commodity with the shelf-life, passed through by the regular hour
After shelf-life, the commodity are just without value.In addition, the form that above-mentioned condition can also be assets changes, when this change
Change when occurring it is necessary to triggering the calcellation of the assets by special transaction data.
For this situation, so that it may to establish a backward chaining by a special deal data-triggered, by before
Designated blocks in transaction data carry out calcellation processing, to abolish before block assets.
3. carrying out feedback control to other areas transaction data in the block by having block in block chain
Here have block in the so-called chain by block and feedback control is carried out to other areas transaction data in the block, that is, refer to
It is not completed not instead of directly, is needed by other by establishing backward chaining between new block by the block of feedback control manipulation
The transaction data content of block successively realizes that feedback, the final result of the feedback operation can open target area business in the block
Data can also be to close target area business datum in the block.
For example, the scheme thought based on backward chaining structure in above-mentioned block chain, it is two-way can to form the chain type as shown in 6
Block chain structure schematic diagram, including：At least one chain type Two-way Chain in Fig. 6 Block2, Block4 and Block5 (as being made of
Chain type Two-way Chain)；
The chain type Two-way Chain is formed by multiple blocks after two opposite direction sequence links, and by the link in rear formation
In direction (by the direction of Block5 → Block4 → Block2 in such as Fig. 6), this is each stored with successively in preceding block preceding
The check value that the latter zone data in the block of block are calculated through non-reversible algorithm.For example, the non-reversible algorithm can be to breathe out
Uncommon algorithm, corresponding check value are cryptographic Hash.
Wherein, so-called multiple blocks refer to first normally prolonging from front to back by block chain along two opposite direction sequence links
The direction of exhibition is first generated as sub-block in rear block based on extending in preceding block as father's block, is then re-formed
Block is directed toward the backward chaining in preceding block afterwards, is so formed Block2 → Block4 → Block5's in similar Fig. 6
What the link direction in rear formation for link direction and Block5 → Block4 → Block2 being previously formed was constituted has double
To the chain of link.And wherein in the definition of preceding block, it is time sequencing definition when normally being generated by block always, that is, presses
The link direction definition being initially formed, if Block2 and Block4 is Block5 always in preceding block in Fig. 6, Block2 is always
Block4 in preceding block.
Correspondingly, by the link direction (by the direction of Block5 → Block4 → Block2 in such as Fig. 6) of rear formation,
Each it is stored with the school that the latter zone data in the block in preceding block are calculated through non-reversible algorithm successively in preceding block
Value is tested, is i.e. is stored with the check value of Block5 in Block4, the check value of Block4 is stored in Block2.
Although two neighboring block father, sub-block each other in theoretical upper chain type Two-way Chain, in the block head of the two blocks
In should all be stored with check value that other side area data in the block are obtained through non-reversible algorithm and seem contradiction, still, due to this two
The link in a direction is logic will not to be caused to obscure through what sequencing generated.For example, first by the link direction being previously formed,
When generating Block4, the data in Block2 are first obtained into check value through non-reversible algorithm, and the check value is recorded in
In the block head of Block4；Then by the link direction of rear formation, then the verification that will include Block2 and Block5
All data in the Block4 of value obtain check value through non-reversible algorithm, and the check value is recorded in the block head of Block2
In.In other words, the check value of former father's block had both been stored in Block2, while the check value of sub-block Block4 is also stored.
In fact, the two-way chain structure of chain type can be considered as the adjacent block of multiple sequences, first along normally extend direction (
The link direction being initially formed) link (direction of Block2 → Block4 → Block5 links) is formed, then extend along with normal
Side in the opposite direction (in the link direction of rear formation) formed link (the direction chain of Block5 → Block4 → Block2
Connect) it is constituted afterwards.
When based on forming backward chaining, need to the areas Liang Ge the repairing in preceding block in the block with backward chaining relationship
Change, so as to cause verification can not by logic, can set should proparea transaction data in the block formed when as closing
State (i.e. transaction data is unavailable) is after forming backward chaining, and transaction data is just arranged, and by unlatching, (i.e. transaction data can
With).Based on the logical relation that this data are opened, in the link direction in rear formation each preceding block due to thereafter
Block formed backward chaining relationship and opened successively, and finally open chain type Two-way Chain in head end area number of deals in the block
According to.The logical relation of above-mentioned unlatching can also be expanded in the chain type Two-way Chain of formation.For example, setting chain type Two-way Chain
In after head end area transaction data in the block is opened, it is also synchronous with other areas transaction data in the block that the head end block links
It is opened.
It is analyzed from the above process, the backward chaining of Block5 → Block4, corresponding feedback control is shown as, and is passed through
Block4 opens the transaction data (backward chaining for establishing Block4 → Block2) in Block2.
For example, in the process field of assets, it is understood that there may be following demand：A collection of money is sold in some designated blocks concentration
Production, but the assets are initially invalid state, and after meeting certain condition, a special friendship is executed in a block later
Easily, the assets of designated blocks before are all started.Above-mentioned condition can be by the regular hour, for example, for some
The commodity of quality inspection phase are still in, after quality inspection passes through, which just has the value of sale.In addition, above-mentioned condition can also
That the forms of assets variation (be initialized as invalid) occurs, when such a change occurs it is necessary to by special transaction data come
It triggers the assets and enters effective status.
For this situation, so that it may successively to establish multiple backward chainings by a special deal data-triggered, until
The designated blocks for including the assets are linked to, and then the transaction data in designated blocks before is subjected to unlatching processing, to
So that the assets of block from becoming effective status in vain before.
What needs to be explained here is that can also remember in the block of non-first and end in chain type Two-way Chain as shown in FIG. 6
Record open its previous block transaction data, only these transaction data just build after be in off state, only the block with
The block of its latter link can just be opened after forming backward chaining by latter zone transaction data in the block, in the block in the area
After transaction data is opened, the backward chaining relationship for establishing the block and its previous block can be continued, and then open previous area
Transaction data in the block；Or these in chain type Two-way Chain positioned at non-first and end block in also can record open it is first
The part transaction data of block, and had recorded in the block of end and open head end area last part transaction data in the block, so
After in end, block is formed, so that it may backward chaining is formed with previous block to be transmitted successively from end region BOB(beginning of block), it is final to open
Head end area transaction data in the block.It can be seen that the end block in chain type Two-way Chain is to open in entire chain type Two-way Chain
Block where the last part transaction data of each block, the only block can just open preceding block successively after being created
In transaction data, or by backward chaining successively to front transfer opening operation until head end block, and in chain type Two-way Chain
Head end area transaction data in the block be the data finally opened.
S330 carries out feedback control manipulation to having the transaction data of block；
Based on the above-mentioned various feedback control logic enumerated, phase can be carried out to having the transaction data of block in block chain
The operation processing answered.Such as：
For the Feedback control logic that the transaction data for having block is closed in block chain, can generate above-mentioned existing area
Be arranged when block transaction data therein be open state, such as by specified identification information identify area part in the block or
All data are available open state.After forming the backward chaining for having and closing these transaction data, this can be had area
Transaction data is in off state from open state switching in block, such as identifies area part in the block by specified identification information
Or all data are not available closed state.Or the mechanism that can not be verified due to modification from existing block because existing
On, it directly identifies this and has the pent state of block.
For the feedback control for carrying out feedback control to other areas transaction data in the block by having block in block chain
Logic can continue to generate and be somebody's turn to do after existing block forms backward chaining, according to the corresponding Feedback control logic of the backward chaining
Has the backward chaining between block and other existing blocks, to form corresponding Feedback control logic, until target control
Logic is completed.It can be to being modified by the existing area transaction data in the block of feedback control when forming backward chaining every time.
Feedback control is carried out to other areas transaction data in the block either by having in block by having block in block chain
Transaction data controls other areas transaction data in the block and is in off state from open state switching, can also be by having in block
Transaction data controls other areas transaction data in the block and is switched to open state from closed state.
S340, by the newly-increased data in the block chain for forming the backward chaining with feedback control manipulation to block chain network
It is broadcasted.
It is carried out before feedback control manipulation is directed to due to the backward chaining of above-mentioned formation, and to having block
There is the modification of block, therefore, after node generates new block, not only to broadcast new block, it is also desirable to which existing area is in the block new
Increase data to be broadcasted to block chain network, with by the common recognition mechanism of multiple nodes to the execution of final block chain verification with
Confirm.
Further, show that new block is controlled by the block of backward chaining institute feedback control and feedback in order to clearer
Logic processed can be recorded in the transaction data of new block by the number of the existing block of feedback control and feedback control letter
Breath, such as control have the logical operation that transaction data is opened, closed in block, or control other by existing block and specify
The logical operation that area's data in the block of block number are opened, closed.
Further or alternatively, area of the new block by backward chaining institute feedback control is shown in order to clearer
Block and Feedback control logic can record the new block of feedback control in by the transaction data of the existing block of feedback control
Number and feedback control information, as control have block in transaction data open, close logical operation；It is either logical
It crosses and has the logical operation that block controls area's data unlatching in the block of other designated blocks number, closing；Or it is direct
Execute the operation etc. modified to having area's transaction data in the block.
Feedback method for treating in the block chain of the embodiment of the present invention, the block points relationship based on backward chaining can be with
It realizes and can have block based on the backward chaining relationship of block chain to the past and carry out feedback control manipulation.
Further, above-mentioned feedback control may include：It opens in block chain and has area's transaction data in the block, closes block
