Description
Technical Field
The embodiment of the invention belongs to the technical field of block chains, and particularly relates to an error surveying method and system for a block chain of an overall serial added block.
Background
With the continuous development of the internet, a block chain technology is produced, and the block chain technology is an internet database technology and has the characteristics of decentralization, openness and transparency. Specifically, the essence of blockchain technology is a decentralized and distributed data storage, transmission and certification method, which replaces the current internet dependency on a central server with data blocks, so that all data changes or transaction items are recorded on multiple book nodes at the same time. Since there is no distributed peer-to-peer network of central control points and a distributed method of collective operation is used, it can be said that the blockchain is a "public big ledger" on the network. The system has a plurality of nodes, each node can observe the whole ledger and participate in maintenance together, the income is the right of obtaining accounting, a complete database can be copied, and a single node cannot modify the database, so that the safety and reliability of ledger data are ensured.
At present, the block chain technology is widely applied to various business fields for organizing and managing data.
In the process of implementing the invention, the inventor finds that the prior art has the following defects:
the existing block chain sequentially generates new blocks along the extension direction of the block chain, and consistency verification is satisfied between the blocks, which also aims to prevent data in the blocks from being maliciously tampered. However, in some cases, when there is an error in the block volume data in a certain block on the blockchain, or the data needs to be modified and corrected due to special needs of the regulatory or policy department, if the data is forcibly modified, the consistency verification of the blockchain is inevitably failed, and thus a contradiction between the modified block data and the blockchain consistency verification occurs.

Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
It should be noted that, the embodiments of the present invention provide a method for correcting a block chain of an overall serially added block, so as to correct a block data in the block chain without modifying the block data in the generated block chain. The whole serial added blocks refer to that for each error-corrected block in the extended block chain, the corresponding copy blocks contain the historical error correction result data until the copy block is generated, and the copy blocks are linked on the extended block chain in a single-chain serial manner. Specifically, a data error correction request aiming at block data of a block in an extended block chain formed currently is received, wherein the data error correction request comprises position information of first data to be corrected in the extended block chain and second data obtained by correcting the first data; generating a copy block corresponding to the data error investigation according to block body data of a first block where the first data are located or block body data of an existing copy block corresponding to the first block and second data, wherein the block body data of the copy block is the same as the block body data of the first block except that the first data in each data error investigation request is modified into corresponding second data; and taking any block in the extended block chain as a parent block, or taking a copy block corresponding to the first block and positioned at the tail end of the block chain as a parent block, taking the currently generated copy block as a child block, and linking the currently generated copy block into the block chain, so that the error correction of the block data is realized by taking the block data in the copy block as the error correction result of the block data in the first block.
Next, the transaction information described in the block volume data of each block in the block chain in the embodiment of the present invention is not limited to the information of "account book" or "financial transaction" in the business, and may be broadly understood as diversified object data that needs to be managed by such a data organization form as the block chain, such as enterprise management data for managing an enterprise, project progress management data for tracking a project, and the like. In the embodiment of the invention, the form and the extension direction of the extension blockchain in the blockchain are not limited, but only in the normal extension process of the extension blockchain, the block body data of the blocks in the blockchain is corrected and corrected in a mode of additionally adding copy blocks in the extension blockchain, and meanwhile, the corresponding block body data part in the original extension blockchain is not required to be modified. For example, the extended block chain may be a conventional single-chain block chain as shown in fig. 1, a block chain in an overall tree structure as shown in fig. 2 (each block in the block chain has only one parent block and one or more child blocks), or a block chain having a directed acyclic pattern structure as shown in fig. 3 (at least one block in the block chain has one or more parent blocks).
The error correction method for the global serial addition block chain according to the embodiment of the present invention will be described in detail below.
Example one
Fig. 4 is a flowchart of an error correction method for a whole chain of serially added blocks according to an embodiment of the present invention, and an execution subject of the method may be a system with a data processing function, including a terminal and/or a server. The embodiment of the invention relates to a concept of an extension block chain, wherein the extension block chain comprises the following components: when a new block is generated for newly generated data, the portion of the blockchain in which the new block is linked throughout the blockchain is referred to as an extended blockchain. In this embodiment, a complete blockchain may include an extended blockchain, or an extended blockchain and at least one copy blockchain linked to the extended blockchain. These duplicate blocks serve the sole purpose of correcting for the errata block data of the blocks in the extended blockchain, and are not considered as new blocks generated for the newly generated data.
As shown in fig. 4, the error checking method for the global serial addition block comprises the following steps:
s410, receiving a data error correction request for the block data of the block in the extended blockchain that has been formed currently, wherein the data error correction request includes: the method comprises the steps of obtaining position information of first data to be subjected to error correction in an extended block chain, and obtaining second data subjected to error correction on the first data;
the extended block chain formed currently refers to a block chain shape which is shown by the formed extended block chain as a whole when the current time is reached.
Specifically, when block data of a block in a currently formed extended blockchain needs to be subjected to a data mining, a data mining request may be sent to the system, where the data mining request includes: the position information of the first data to be error-corrected in the extended block chain, and the second data after error correction of the first data. The first data is partial block volume data located in a block of the extended block chain, and the partial block volume data is used as target data of the error investigation, and the first data may be data only including the data to be investigated, or a data set including the data to be investigated.
For convenience of describing the tile volume data of each tile (including the tile in the extended blockchain and the duplicate tile), in this embodiment, the tile volume data of each tile in the blockchain is divided into a plurality of data entries, each data entry independently contains one piece of transaction information and corresponds to one data ID, for example, as shown in fig. 5, it shows the existence form of the tile volume data in the blockchain, that is, the tile volume data of each tile may include a plurality of data entries. In fig. 5, in the extended Block chain consisting of Block1, Block2, and Block3 … …, tx01 located in Block 2: olddata, as a data entry, has a data ID of tx01 and transaction information of olddata (olddata generally refers to original transaction information in the extended block chain that has not been reconsidered yet). In fact, the first data may be transaction information corresponding to one or more data entries to be investigated, or may be a set of data including the transaction information to be investigated. For convenience of data management, the system in this embodiment processes data error requests one by one in units of data entries in block data existing in a block chain when receiving and processing the data error requests, that is, each received data error request only includes a data error request for one data entry.
Specifically, when the blockchain manager needs to perform the mining on the blockbody data of the blocks in the extended blockchain, the location information of the first data to be mined in the extended blockchain may be input to the system, where the location information may specifically be the number of the Block in which the first data is located (the number of each Block in the blockchain is uniquely determined, such as "Block 1", "Block 2", "Block 3" in fig. 5, which may be used as the number of the Block), and the data ID of the first data in the blockbody data of the Block (such as "tx 01" in fig. 5). By locking the block number of the first data in the extended block chain and the data ID in the block data of the block, a data entry and the transaction information contained in the data entry can be uniquely determined. Therefore, it should be noted here that the error correction for the transaction information in a certain data entry is already determined when the data correction is determined, and when the data correction is specifically performed, only the position information of the corrected data, i.e., the first data, in the extended block chain needs to be locked, and the specific content of the first data does not need to be explicitly input into the system.
The second data is data obtained by error correction of the first data, that is, the second data is used to replace the portion of the first data corresponding to the first data. The data error request input to the system comprises two parts, namely: the position information of the first data to be error-corrected in the extended block chain, and the second data after error correction of the first data.
In an actual application scenario, a blockchain manager may input position information of a plurality of transaction information in a blockchain and result information obtained by performing error correction on the transaction information to the system at one time, and the system may analyze information items corresponding to the transaction information according to the position information of the transaction information in the blockchain, so that the information items are treated as a plurality of data error correction requests by taking the information items as a unit, that is, each data error correction request only includes a data error correction request for one data item.
S420, generating a copy block corresponding to the data error correction according to the block data of the first block where the first data is located or the block data of the existing copy block corresponding to the first block and the second data, wherein the block data of the copy block is the same as the block data of the first block except that the first data in each data error correction request is modified into the corresponding second data.
Specifically, the system extracts position information of first data to be subjected to error correction in an extended block chain from a received data error correction request, finds a block where the first data is located, namely a first block, according to the position information of the first data in the block chain, and generates a copy block according to block body data in the first block or block body data of an existing copy block corresponding to the first block and the second data.
Specifically, if there is no duplicate block corresponding to the first block in which the first data that is mistaken at this time is located in the block chain by the current time, the duplicate block may be generated according to the block volume data in the first block. For example, the block volume data of the first block may be copied, the first data in the copied data may be replaced with the second data, and the copied data after replacement may be used as the block volume data to generate the copy block, where the block volume data of the copy block is the same as the block volume data of the first block as a whole, except that the first data is modified into the second data. If the copy block corresponding to the first block where the first data which is mistaken at this time is located exists in the block chain by the current moment, the copy block required by the error at this time can be generated according to the block body data in the existing copy block. For example, when each existing copy block includes result data of past data error before the copy block is generated, block volume data in the copy block closest to the generation time data in the existing copy block may be copied, then first data in the copy data (data at the same position in the copy block as the corresponding original block in the extended block chain may be determined as the first data) may be replaced with second data, and the copy block may be generated by using the replaced copy data as block volume data.
Here, the data content of the chunk header of the copy chunk is not limited in this embodiment, and the administrator may add control information to the chunk header according to the requirement. For example, the block header of the copy block erroneously generated in the current survey may be added with the generation time information of the copy block and/or the position information of the first data erroneously generated in the extended blockchain; for another example, the version number corresponding to the copy block is added to the block header of the copy block that is generated by mistake in the current survey. When a plurality of replica blocks are generated by performing error correction on block volume data in the same block in the extended block chain for a plurality of times, version numbers can be added to the replica blocks in sequence according to error correction time so as to distinguish error correction versions.
S430, using any block in the extended block chain as a parent block, or using a duplicate block corresponding to the first block and located at the end of the block chain as a parent block, and using the currently generated duplicate block as a child block, linking the currently generated duplicate block into the block chain, so as to form the following block chain form: the copy blocks corresponding to the first block are linked in a single-chain bar form.
Specifically, if a duplicate block corresponding to a block where the first data which is mistaken at this time is located does not exist in the block chain by the current time, one block can be arbitrarily selected from the extended block chain as a parent block; if the copy block corresponding to the block where the first data which is mistaken at this time is located exists in the block chain by the current moment, selecting one copy block located at the tail end of the block chain from the copy blocks as a parent block; and linking the copy blocks into the block chain by taking the currently generated copy blocks as the sub-blocks, thereby performing error correction on the block volume data of the blocks in the extended block chain in a mode of additionally adding the copy blocks on the extended block chain.
When a block is selected from the extended blockchain as a parent block of the currently generated duplicate block, the selection may be arbitrary in principle as long as the correspondence between the duplicate block and the block that is mistakenly found can be represented (the correspondence may be realized by adding control information to the block header of the duplicate block or by the link relationship between blocks). However, in order to more clearly show the relationship between the surveyed block and the duplicate block, the block chain may be extended, where the first block where the first data surveyed this time is located is used as a parent block, and the duplicate block generated currently is used as a child block, and the duplicate block is linked into the block chain.
As shown in fig. 6a, is a blockchain morphogram that is formed after linking copy blocks into a blockchain. In the figure, data with data IDs of "tx 01" and "tx 02" in Block "Block 2" in the extended Block chain are respectively surveyed in the copy Block "Block 2(ver 2.0)" and the copy Block "Block 2(ver 3.0)". In this embodiment, in the block data table corresponding to the block chain, the default is that the version number of each original block in the extended block chain is ver1.0, and then the original block number + the version number can be used as the final block number, for example, the block number of the original block: "Block 2(ver 1.0)", Block number of copy Block: "Block 2(ver 2.0)", "Block 2(ver 3.0)".
Taking fig. 6a as an example, the information of the original block corresponding to the block and the data ID corresponding to the first data that is mistaken may also be added to the block header of the formed duplicate block. For example, information is added to the Block header of Block2(ver 2.0): "ver 1.0Block2(ver 1.0)" and "tx 01", add information in the Block header of Block2(ver 3.0): "ver 1.0Block2(ver 1.0)", tx01 and "tx 02".
In addition, in a specific application scenario, there may be a case where multiple error mining is performed on the same first data of an original Block, and each error mining generates a higher version copy Block correspondingly, as shown in fig. 6b, which is a Block chain formed after multiple error mining is performed on the first data with data ID tx01 in the original Block2(ver1.0), where Block2(ver2.0) is the copy Block formed after the first data is subjected to the first error mining, and Block2(ver3.0) is the copy Block formed after the first data is subjected to the second error mining.
After a data error-surveying request is received, generating a copy block corresponding to the data error survey according to position information of first data to be surveyed in the data error-surveying request in an extended block chain and second data obtained by surveying the first data, wherein block body data of the copy block is the same as block body data of a first block where the first data is located, except that the first data in each data error-surveying request is modified into corresponding second data, other data are the same; taking any block in the extended block chain as a parent block, or taking a copy block corresponding to the first block and positioned at the tail end of the block chain as a parent block, taking the currently generated copy block as a child block, and linking the currently generated copy block into the block chain, so that the copy blocks corresponding to the first block are linked in a single-chain bar form, and under the condition that the block body data in the generated block chain is not modified, the error correction of the block body data in the original block is realized by integrally and serially adding the copy blocks in the block chain.
Further, in the block header of the generated copy block, for example, the generation time information of the copy block and/or the position information of the surveyed first data in the extended blockchain may be added, and the version number corresponding to the copy block may also be added, so that the attribute information of the copy block and the corresponding relationship between the copy block and the corresponding surveyed block may be clearly embodied, and the reference is facilitated.

4. A method of surveying error according to any of claims 1-3, characterized in that the position information of the first data in the extended blockchain comprises: the number of the block where the first data is located, and the data ID of the first data in the block body data of the block.
5. An error correction system for global serial addition of blockchains of blocks, wherein the blockchains comprise an extended blockchain and at least one copy block linked to the extended blockchain,
the error surveying system comprises:
a data error correction request receiving module, configured to receive a data error correction request for the block body data of a currently formed block in the extended block chain, where the data error correction request includes: the position information of the first data to be surveyed in the extended block chain and the second data after the first data are surveyed;
a copy block generation module, configured to generate a copy block corresponding to the current data reconnaissance according to block volume data of an existing copy block corresponding to a first block where the first data is located and the second data, where the block volume data of the copy block corresponding to the current data reconnaissance is smaller than the block volume data of the first block, and except that the first data in each data reconnaissance request is modified into the corresponding second data, other data are the same;
a duplicate block linking module, configured to link a currently generated duplicate block to the blockchain by using a duplicate block at an end of the blockchain corresponding to the first block as a parent block and using the currently generated duplicate block as a child block, so as to form a following blockchain form: linking the copy blocks corresponding to the first block in a single-chain bar form, wherein when the current moment is reached and the copy block corresponding to the block where the first data which is mistaken at this time is located does not exist in the block chain, one block is arbitrarily selected from the extended block chain to serve as a father block; when the copy block corresponding to the first block already exists in the blockchain by the current time, one copy block at the tail end of the blockchain is selected from the copy blocks corresponding to the first block to serve as a parent block.
6. The error surveying system of claim 5, further comprising:
and the information adding module is used for adding the generation time information of the copy block and/or the position information of the mistaken first data in the extended block chain to the block head of the copy block generated by mistake in the current survey.
7. The error surveying system of claim 5, further comprising:
and the information adding module is used for adding the version number corresponding to the copy block to the block head of the copy block which is generated by mistake in the survey.
8. The error surveying system of any one of claims 5-7, wherein the position information of the first data in the extended blockchain comprises: the number of the block where the first data is located, and the data ID of the first data in the block body data of the block.
