According to first data can be the data for only including being corrected errors in printing, or contain the data acquisition system including the data corrected errors in printing.
In order to facilitate the block body of each block in description block chain (including block and copy block in extension block chain)
Data, the present embodiment divide the block volume data of each block in block chain for multiple Data Entries, in each Data Entry
Independent includes a Transaction Information, and a corresponding data ID, such as shown in Fig. 5, it illustrates block body in block chain
The existence form of data, i.e., it can include a plurality of Data Entry in the block volume data of each block.In Fig. 5, by Block1,
In Block2 and the extension block chain of block3 ... compositions, the tx01 in block Block2：Olddata, as one
Data Entry, its data ID are tx01, and Transaction Information is that (olddata refers to not to be corrected errors in printing also olddata in extension block chain
Original transaction information).In fact, above-mentioned first data can be handed over corresponding to one or more of Data Entries to be corrected errors in printing
Easy information or the set for including the data including these Transaction Informations to be corrected errors in printing.In order to facilitate data management, this reality
The system in example is applied when receiving and processing data corrigenda request, is with the number in already present block volume data in block chain
It is unit according to entry, handles one by one, i.e., the number for a Data Entry is only included in the data corrigenda request received every time
Asked according to corrigenda.
Specifically, can when the block volume data of block during block chain manager needs to extension block chain is corrected errors in printing
The positional information of the first data to be corrected errors in printing in extension block chain is inputted to system, the positional information can be specifically the first number
According to the block at place numbering (numbering of each block uniquely determines in block chain, as " Block1 " in Fig. 5, " Block2 ",
" Block3 ", can be as the numbering of block), and data ID (such as Fig. 5 of first data in the block volume data of block
In " tx01 ").Pass through the block number where locking the first data in extension block chain, and the block body in the block
Data ID cans in data uniquely determine a Data Entry and its comprising Transaction Information.Therefore, need exist for illustrating
, for the Transaction Information in some Data Entry correct errors in printing just has determined when determining to carry out data corrigenda,
And when specifically performing data corrigenda, it is only necessary to which locking is position of first data in the extension block chain by corrigenda data
Information, the particular content without clearly inputting the first data to system again.
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.

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.
S420, the block volume data of the first block and the second data according to where the first data generate the corrigenda of this data
Corresponding copy block, the block volume data of the copy block compared with the first block block volume data, except the first data are changed
Outside for the second data, other data correspond to identical.
Specifically, system extracts the first data to be corrected errors in printing in extension block chain from the data corrigenda request of reception
In positional information, and the second data after being corrected errors in printing to the first data, and the position according to the first data in block chain
Confidence breath finds block where the first data, i.e. the first block, and according to the block volume data in first block and the
Two data ghost blocks.For example, first the block volume data of the first block can be replicated, then by replicate data
First data replace with the second data, and are used as block volume data ghost block, the copy using the replicate data after replacement
The block volume data of block is corresponding identical on the whole, differed only in, by first compared with the block volume data of the first block
Data modification is for the second data.
