In：First data record is used for the block volume data of original block in memory block chain, and the second data record is used for memory block
The block volume data of copy block in chain.Original block is with being formed after being corrected errors in printing to the block volume data of the original block
There is incidence relation, the incidence relation can pass through increasing in the first data record and/or the second data record between copy block
Add identification information to embody, for example, adding position of the first data corrected errors in printing in extension block chain in the second data record
Confidence ceases.
In order to facilitate storage state of the block volume data in tables of data of each block in description block chain, first to block
The block volume data of block (original block and copy block do not distinguish here) is simply described as follows in chain.The present embodiment
The block volume data of each block in block chain is divided for multiple Data Entries, it is independent in each Data Entry to include one
Transaction Information, and a corresponding data ID, such as shown in Fig. 5, it illustrates the block volume data of block in block chain to deposit
A plurality of Data Entry can be included in form, i.e., the block volume data of each block.In Fig. 5, by Block1, Block2 and
In the block chain of block3 ... compositions, the tx01 in block Block2：Olddata, as a Data Entry, it is counted
It is tx01 according to ID, Transaction Information is olddata (olddata refers to the original transaction information do not corrected errors in printing also in block chain).
In fact, above-mentioned first data, the second data can be handed over corresponding to the one or more of Data Entries in block volume data
Easy information.For the ease of the explanation of subsequent processes content, first data or second data here correspond to block
A data entry in chain.
When the block volume data of block during block chain manager needs to block chain is corrected errors in printing, it can input and treat to system
Positional information of first data in block chain of corrigenda, the positional information can be specifically the volumes of the block where the first data
Number (numbering of each block uniquely determines in block chain, as " Block1 " in Fig. 5, " Block2 ", " Block3 ", can conduct
The numbering of block), and data ID (" tx01 " in such as Fig. 5) of first data in the block volume data of block.Pass through
The block number that the first data are locked where in block chain, and the data ID cans in the block volume data of the block
Uniquely determine a Data Entry and its comprising Transaction Information.Therefore, explanation is needed exist for, for some Data Entry
In Transaction Information carry out corrigenda determine carry out data corrigenda when just have determined, and specifically perform data corrigenda
When, it is only necessary to locking is positional information of first data in block chain by corrigenda data, without clear and definite to system again
Input the particular content of the first data.
The second described data, refer to the first data corrected errors in printing after data, that is, be used for replace the first data corresponding to
Part data.Include two parts content in the data corrigenda request inputted to system, i.e.,：First data to be corrected errors in printing are being prolonged
Positional information in the block chain of exhibition section, and the second data after being corrected errors in printing to the first data.
In practical application scene, block chain manager may disposably input a plurality of Transaction Information in block to system
Positional information in chain, and the object information after being corrected errors in printing to these Transaction Informations, system can be according to these Transaction Informations
Positional information in block chain, the data entries corresponding to it are analyzed, so as in units of data entries, be regarded as multiple
Data corrigenda request is handled, i.e., only please comprising the data corrigenda for a Data Entry in each data corrigenda request
Ask.
In the present embodiment, the mode that the block volume data in block chain is corrected errors in printing is by increasing copy block reality
Corrigenda corrigendum now is carried out to the block volume data of original block.Corresponding to the overall corrigenda method for showing increase block such as Fig. 6 a
A kind of aspect graph of block chain.
Based on the existence of the block volume data of block in the above-mentioned chain to block, can understand first in explanation tables of data
The meaning of data record and the second data record.
Table 1 is the particular content corresponding to Fig. 6 a tables of data.
The tables of data of table 1
| Data ID | First data | Second data | Block number | …… |
| tx01 | olddata1 | (sky) | Block2ver:1.0 | …… |
| tx02 | olddata2 | (sky) | Block2ver:1.0 | …… |
| tx01 | (sky) | newdata1 | Block2ver:2.0 | …… |
| tx02 | olddata2 | (sky) | Block2ver:2.0 | |
| tx01 | (sky) | newdata1 | Block2ver:3.0 | …… |
| tx02 | (sky) | newdata2 | Block2ver:3.0 | …… |
| …… | …… | …… | …… | …… |
In table 1, the record comprising the first data is designated as the first data record, and the record comprising the second data is designated as the second number
According to record.In Fig. 6 a, the data ID in block " Block2 " in extension block chain is respectively the data of " tx01 " and " tx02 "
Corrected errors in printing in copy block " Block2 (ver2.0) " and copy block " Block2 (ver3.0) ".In the present embodiment,
In block data table corresponding to block chain, the version number for each original block that can be defaulted as in extension block chain is ver1.0, then
Can be using former block number+version number as final block number, for example, the block number of original block：“Block2
(ver1.0) ", the block number of copy block：“Block2(ver2.0)”、“Block2(ver3.0)”.
In addition, in concrete application scene, it is also possible to which same first data existed for an original block carry out multiple
The situation of corrigenda, every time corrigenda can correspond to the copy block for generating a more highest version, and such as Fig. 6 b, it is for original block
The block chain that data ID by tx01 the first data formed after repeatedly correcting errors in printing in Block2 (ver1.0), wherein,
For first data are carried out with the copy block that is formed after first time corrigenda, Block2 (ver3.0) is Block2 (ver2.0)
First data are carried out second with the copy block formed after correcting errors in printing.
In the tables of data of the present embodiment, the first data record contains the area of original block in current established block chain
The particular content of positional information and first data of first data in block chain in block data, wrap in the second data record
Positional information and second data of second data in block chain in the block volume data of copy block in block chain are contained
Content information, while the first data for being corrected errors in printing and position of second data in block body after being corrected errors in printing to first data
Put (data ID is corresponding identical).For the querying method for the block chain integrally corrected errors in printing for increasing block, its core in this programme
Thought wants that data are carried out in the second data record corresponding with copy block of the first data record corresponding to original block to be looked into
Ask the process with data processing.
As shown in figure 4, it should comprise the following steps for the querying method of the block chain integrally corrected errors in printing of increase block：
S410, the data inquiry request for the block volume data of block in current established extension block chain is received,
The data inquiry request includes：The key message of target data to be checked；
Wherein, described current established extension block chain refers to the extension block chain by current time, formed
The block chain form presented on the whole；The key message of the target data to be checked can be had in block volume data
Positional information of first data in block chain corresponding to the partial content of the Transaction Information of body or the Transaction Information,
The numbering of block as where the first data, and the data ID of first data in the block volume data of block etc..
Specifically, after system receives the data inquiry request of consultant's input, extract and be used to inquire about mesh in the request
Mark the key message of data.
S420, according to key message, inquired about in the 3rd data record in tables of data, to obtain and key message
The target data record of matching；3rd data record includes：In the absence of corresponding to copy block original block associated with it
First data record, and exist corresponding to the copy block generated the latest corresponding to copy block original block associated with it
Second data record；
Semanteme can be used to obtain the method for target data record by carrying out Data Matching in tables of data according to key message
The methods of similarity, regular expression.The present embodiment to specific implementation information matches used by technology and principle do not limit.
But to the scope of the object data for Data Matching with requiring as follows, i.e.,：
In the absence of the first data record corresponding to copy block original block associated with it, and exist copy block with
Second data record corresponding to the copy block generated the latest corresponding to its original block associated.
Specifically, when the original block in block chain is without the copy block associated, then by such original block
First data record corresponding in tables of data is as the object data for Data Matching, when the original block tool in block chain
During related copy block, then by the copy block generated the latest in the copy block associated by such original block in number
According to corresponding second data record in table as the object data for Data Matching.The first number in the object data selected
It is otherwise known as the 3rd data record according to record and the second data record.
S430, by the data output in target data record.
Using the data record to match with key message obtained from each 3rd data record as target data record
Exported, make it that be presented to consultant is the block volume data after corrigenda is corrected.
It should be noted that in practical application scene, for the block body number of a certain original block in extension block chain
Repeatedly corrected errors in printing according to there may be, and there is the copy block of multiple associations.Such as the region of initiation as shown in Fig. 6 a, Fig. 6 b
Two copy blocks " Block2 (ver2.0) " associated with it, " Block2 be present in block " Block2 (ver1.0) "
(ver3.0)”。
In order to embody the order of the copy block generation corresponding to each second data record in tables of data, in each second number
According to may also include in record：For marking the version number of the copy block where the second data in second data record；This
In the size of version number sequentially increase with the production time of copy block.Such as " Block2 in Fig. 6 a, Fig. 6 b
(ver2.0) ", ver2.0, ver3.0 in " Block2 (ver3.0) " are version number corresponding to respective copies block.
Accordingly, can be corresponding by the plurality of copy block if multiple copy blocks be present for same original block
The second data record in, comprising the data record of version number's highest second as the 3rd data record.
Specifically, the create-rule according to version number in copy block, comprising in the data record of version number's highest second
Include the result data after all previous corrigenda in the original block of its corresponding corrigenda.Therefore version number's highest second will can be included
Data record is as the 3rd data record, so as to ensure to choose the second number as in the second data record of the 3rd data record
According to the data for being the latest edition corrected errors in printing.
It is further noted that after this programme basic goal to be reached is to provide for the corrigenda newest to consultant
Block volume data, these block volume datas are probably to come from the first data record corresponding to original block, it is also possible to copy
Second data record corresponding to block, and consultant for these data whether be corrigenda after data be imperceptible.Example
Such as, when the target data record of output is positioned at copy block block2 (ver:2.0) when, data ID is tx01 data, look into
Reader can not also know that the data are the data corrected errors in printing or the data do not corrected errors in printing.
In order that learning whether the data are corrected errors in printing in the target data record that user obtains from inquiry, this programme is above-mentioned
On the basis of protocol step, following steps are added：
If for choosing in the second data record as the 3rd data record, exist in the second data and tables of data
First data are content identical data, then the first data record comprising first data are replaced into second data record
As the 3rd selected data record.
Specifically, if choosing the second data record the first data corresponding with original block as the 3rd data record
Record it is identical, then show second data be not be directed to original block in block volume data corrected errors in printing after data, this
When can using comprising the first data record with second the first data of data content identical replace second data record as
The 3rd selected data record.
Operated based on the processing, one is only existed for the second data in the second data record as the 3rd data record
Kind situation, it is exactly the second data corrected errors in printing corresponding to the first data, and the data for not corrected errors in printing in the 3rd data record,
It is entirely located in the first data record corresponding to original block.Therefore, in the target data record of output, by checking this
(have version number can check version number to positional information of the first data or the second data that data record includes in block chain
Information) it is known that whether the data are corrected errors in printing.For example, working as positional information in the data record exported corresponds to original block
Position and/or version number be minimum version number, then illustrate that the target data was not corrected errors in printing；When the data record middle position of output
Confidence breath is not least version number corresponding to the position of copy block and/or version number, then illustrates that the target data was corrected errors in printing,
And corrected errors in printing in the copy block corresponding to the data record.
In the present embodiment, it may also include in the second data record：The generation temporal information of this data record；And again
Reaffirm, positional information of first data in block chain may include：The numbering of block where first data, and first number
According to the data ID in the block volume data of block；Positional information of second data in block chain may include：Second data institute
Block numbering, and data ID of second data in the block volume data of the block.
The querying method of the block chain integrally corrected errors in printing for increase block of the embodiment of the present invention, according to the data of reception
Key message in inquiry request carries out data query in the 3rd data record and obtains target data record, the 3rd data
Record includes：In the absence of the first data record corresponding to copy block original block associated with it, and copy block be present
Second data record corresponding to the copy block generated the latest corresponding to original block associated with it；Then target data is remembered
Data output in record, the data corrected so as to ensure the target data of output to be corrected errors in printing for block chain warp.
Further, when choosing three data records, there are multiple copy blocks for same original block
Scheme refinement is carried out.So that during inquiry is performed, the number being queried is embodied by the target data record of output
According to whether being corrected errors in printing, and the specifying information corrected errors in printing in which copy block so that consultant can more clearly obtain
Know the relevant information of inquired about result data.
