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.
Before describing the contents of the embodiments of the present invention, the following terms are explained:
data snapshot: the data replication is not completely the same, and a result after the data snapshot is the same as partial data existing between the original data of the executed snapshot, which may specifically be: the data after snapshot is completely the same as the original data, all the data after snapshot is the same as partial data of the original data, and partial data in the data after snapshot is the same as all or partial data in the original data;
nth dimension space block chain: the multi-dimension (n-1) space block chains comprise a plurality of n-1 space block chains with link relations, wherein the link relations between the two block chains mean that at least two blocks exist as parents and children between the two block chains, and the multi-dimension (n-1) space block chains with link relations mean that the multi-dimension (n-1) space block chains exist with link relations with each other to form a block chain which is linked with each other integrally.
The nth dimension space snapshot object block chain: the nth dimensional space block chain which is executed with the data snapshot operation is marked as the nth dimensional space snapshot object block chain corresponding to the current snapshot;
the nth dimensional spatial snapshot result block chain: and after the snapshot operation is carried out on the nth dimensional space block chain, a result block chain which is relative to the nth dimensional space snapshot object block chain is generated.
Dimension expansion, namely performing overall dimension upgrading on the basis of a currently formed block chain of a certain dimension space, wherein before and after dimension expansion, the dimension of the block chain is increased if the nth dimension space block chain is integrally upgraded to the (n + 1) th dimension space block chain;
and dimension extension, namely based on a currently formed block chain of a certain dimension space, performing block extension under the dimension to add blocks, for example, adding new blocks on one or more (n-1) th dimension space block chains included in the nth dimension space block chain, wherein the dimension of the block chain is unchanged before and after the dimension extension. In the n + 1-dimensional space, block extension may be performed on each nth-dimensional space block chain according to different dimensional parameters, such as time, block scale, and other dimensional parameters, where each dimensional parameter corresponds to a specific block extension rule, for example: the extension rule corresponding to the time dimension parameter may be that data snapshot is performed on an nth dimension space block chain in an n +1 th dimension space block chain formed currently every fixed time period, and a block chain generated after snapshot is linked to the nth dimension space block chain; for another example, the extension rule corresponding to the block scale dimension parameter may be that, for an nth dimensional space block chain in an n +1 th dimensional space block chain currently formed, after a fixed number of blocks are added, a data snapshot is performed on the nth dimensional space block chain, and a block chain generated after the snapshot is linked to the nth dimensional space block chain; this can also be referred to as dimensional extension in dimension for the (n + 1) th dimensional space block chain by different dimensional parameters.
First, it should be noted that, in the embodiments of the present invention, a method for generating a central multidimensional expansion block chain is provided, where before and after each dimension expansion, the dimension of the block chain is increased by one dimension. Performing data snapshot on a currently formed nth dimensional space block chain to generate one or more nth dimensional space snapshot result block chains corresponding to the nth dimensional space block chain, wherein the nth dimensional space snapshot result block chain is in a first link relation with each block in the nth dimensional space snapshot object block chain, the contents of block data in the blocks are correspondingly the same, and the original nth dimensional space block chain is marked as the nth dimensional space snapshot object block chain; taking each block in the nth dimensional spatial snapshot object block chain as a parent block, taking each block in the nth dimensional spatial snapshot result block chain corresponding to each parent block as a child block, and performing combined linking on the nth dimensional spatial snapshot object block chain and the nth dimensional spatial snapshot result block chain to form a second linking relation; and according to the first link relation and the second link relation, sequentially generating a hash value of each block in the one or more nth dimensional spatial snapshot result block chains, and writing the hash value into each corresponding block to form an nth +1 dimensional spatial block chain, wherein the one or more nth dimensional spatial snapshot result block chains and the nth dimensional spatial snapshot object block chain are respectively used as each nth dimensional spatial block chain in the nth +1 dimensional spatial block chain. The block volume data described herein is understood to be information as actual transaction data, and the block header data includes a hash value, which is a fixed-length character string generated by an irreversible algorithm on all data of a parent block of the current block, and control information related to the current block, and the block volume data and the block header data constitute complete data of one 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 dimension extension direction of each dimension block chain are not limited, and the overall dimension expansion of the current block chain is realized through the data snapshot only in the normal extension process of the block chain. For example, the block chain of the first dimension space may be in the form of a conventional single-chain block chain as shown in fig. 1, or may be in the form of an overall tree-like block chain as shown in fig. 2 (each block in the block chain has only one parent block and one or more child blocks), or may be in the form of a directed acyclic graph structure as shown in fig. 3 (at least one block in the block chain has one or more parent blocks).
The following describes a method for generating a block chain of a central multidimensional extension according to an embodiment of the present invention in detail.
Example one
Fig. 4 is a flowchart of a first method for generating a central multidimensional expanded block chain according to an embodiment of the present invention. As shown in fig. 4, the block chain generating method includes the following steps:
s410, performing data snapshot on a currently formed nth dimensional space block chain to generate one or more nth dimensional space snapshot result block chains corresponding to the nth dimensional space block chain, marking the original nth dimensional space block chain as an nth dimensional space snapshot object block chain, and correspondingly enabling the first link relation between the nth dimensional space snapshot result block chain and each block in the nth dimensional space snapshot object block chain and the content of block data in the blocks to be the same; the nth dimension space block chain comprises a plurality of nth-1 dimension space block chains with a link relation;
the currently formed nth dimensional space block chain refers to a block chain form and a corresponding highest dimension which are presented by the formed block chain on the whole by the current time, and n is an integer greater than 0. The nth dimensional space block chain comprises a plurality of nth-1 dimensional space block chains with a link relationship, wherein the link relationship among the plurality of nth-1 dimensional space block chains does not limit which blocks are linked with each other and the number of the blocks and the specific link relationship (parent-child relationship) among the blocks, as long as the link relationship among the nth-1 dimensional space block chains is satisfied, and the nth-1 dimensional space block chains can be linked into a whole block chain through the link relationship.
Specifically, after a triggering condition of one-time dimension expansion is reached, data snapshot is performed on the currently formed nth dimensional spatial block chain, and one or more nth dimensional spatial snapshot result block chains corresponding to the nth dimensional spatial block chain are generated.
It should be noted that the process of the data snapshot in this embodiment is an operation of partially copying and/or entirely copying and/or modifying the content of the snapshot object. The operation is only used for enabling the block volume data of each block in the nth dimensional space snapshot result block chain and the nth dimensional space snapshot object block chain generated after the data snapshot to be corresponding to the same, and enabling the link relation among the blocks to be corresponding to the same. The link relationship between the blocks in the nth dimensional spatial snapshot object block chain is integrally defined as the first link relationship, and since the link relationship between the generated nth dimensional spatial snapshot result block chain and the blocks in the corresponding nth dimensional spatial snapshot object block chain is the same after the data snapshot, the link relationship between the blocks in the nth dimensional spatial snapshot result block chain can also be integrally defined as the first link relationship. The link relation between the blocks refers to the parent-child relation existing between the blocks, and the parent-child relation does not require that the consistency verification is carried out through the hash value in the block header data in the blocks. In other words, the linking relationship in this embodiment is only to express a linking frame between blocks, and is not used as a definition scope for specifying consistency verification between blocks.
In a specific application, the purpose of the data snapshot is to make the nth dimensional spatial snapshot result block chain and the nth dimensional spatial snapshot object block chain be the same in the overall architecture of the block chain, and the block volume data in each block is also the same correspondingly, and the data in the block header may be the same or different, even in the nth dimensional spatial snapshot result block chain, there is no substantial data in the block header of each block, which needs to be determined according to specific requirements.
In the process of the method for generating the central multidimensional expanded block chain, in order to reduce the complexity of subsequently calculating the hash value of each block, the block head data of each block in each nth dimensional space snapshot result block chain obtained through the data snapshot is default to be null. Therefore, it can be considered that the nth dimensional spatial snapshot result block chain obtained after the data snapshot is an "incomplete" block chain, and the block header of each block in the block chain does not include a hash value that can verify the consistency of the block chain. Only if hash values are added to the block headers of the blocks of the nth dimensional spatial snapshot result block chains and the hash values satisfy the consistency verification requirements of the block chains, the block chains are considered to be a 'complete' block chain.
For example, fig. 5 shows a morphological example of the corresponding nth dimensional spatial snapshot object block chain and nth dimensional spatial snapshot result block chain after the data snapshot. As can be seen from the figure, the nth dimensional spatial snapshot object block chain and the nth dimensional spatial snapshot result block chain (an nth dimensional spatial snapshot result block chain is taken as an example in the figure for explanation) are the same in the overall configuration architecture, the linking relationship (the first linking relationship) between the blocks in the two block chains is the same correspondingly, and the block data in the blocks are the same correspondingly, the block header data is not necessarily the same, even the block header data of each block in the nth dimensional spatial snapshot result block chain may be null.
S420, taking each block in the nth dimensional spatial snapshot object block chain as a parent block, taking each block in the nth dimensional spatial snapshot result block chain corresponding to each parent block as a child block, and performing combined linking on the nth dimensional spatial snapshot object block chain and the nth dimensional spatial snapshot result block chain to form a second linking relation;
for example, in fig. 5, a block a and a block B in the nth dimensional spatial snapshot object block chain are used as parent blocks, and a block a1 corresponding to the parent block a in the nth dimensional spatial snapshot result block chain is used as a child block of the block a; the block B1 corresponding to the parent block B is used as a child block of the block B, so that the nth dimensional spatial snapshot object block chain and the nth dimensional spatial snapshot result block chain are combined and linked to form a second linking relationship. The second link relationship is a general term of all link relationships between the nth dimensional spatial snapshot object block chain and the nth dimensional spatial snapshot result block chain. Fig. 6 shows a block chain state diagram after the n-dimensional spatial snapshot object block chain and the n-dimensional spatial snapshot result block chain are combined and linked. It should be noted that, by combining and linking the nth dimensional spatial snapshot object block chain and the nth dimensional spatial snapshot result block chain, only the link relationship between the two block chains is determined, and consistency verification after block chain linking is not involved, so that in the block chain formed after combining and linking, the block header data of each block in the nth dimensional spatial snapshot result block chain is still undefined.
In the block chain configuration diagrams shown in fig. 5 and 6, the block header data of each block in the snapshot result block chain is not limited, and therefore "block header data? "show.
And S430, according to the first link relation and the second link relation, sequentially generating hash values of the blocks in the nth dimensional spatial snapshot result block chain, and writing the hash values into the block headers of the corresponding blocks to form an nth +1 dimensional spatial block chain, wherein each nth dimensional spatial snapshot result block chain and each nth dimensional spatial snapshot object block chain are respectively used as each nth dimensional spatial block chain in the nth +1 dimensional spatial block chain.
For example, taking the block chain form shown in fig. 6 as an example, according to a first link relationship of each block in the nth dimensional spatial snapshot result block chain and a second link relationship between the nth dimensional spatial snapshot result block chain and the nth dimensional spatial snapshot object block chain, a parent-child relationship between the corresponding blocks is determined, and then according to the parent-child relationship, hash values of each block in the nth dimensional spatial snapshot result block chain are sequentially generated and written into block headers of the corresponding blocks, so as to form the (n + 1) th dimensional spatial block chain in the form shown in fig. 7.
As shown in fig. 7, the "sequential generation" here means that a hash value of the block a1 is generated first, the hash value is a fixed-length character string generated by an irreversible algorithm on all data in the parent block a of the block a1, and the hash value provides a guarantee for the existence and non-tampering of a plaintext into a block chain. After the hash value of the block a1 is obtained, the hash value is added to the block header of the block a1, the block header data A3 of the block a1, the block body data a2 and the block header data A3 together form complete data of the block a 1; then, by parent-child relationship between the blocks (determined by the first link relationship and the second link relationship), a hash value of the block B1 is calculated, the hash value including two fixed-length character strings, each generated by an irreversible algorithm, of all data in the parent block a1 of the block B1, and a fixed-length character string generated by an irreversible algorithm, of all data in the parent block B of the block B1, the two hash values being added to the block header of the block B1, respectively, the block header data B3 constituting the block B1, the block body data B2 and the block header data B3 together constituting the complete data of the block B1. After the block header data of each block in all the nth dimensional spatial snapshot result block chains are sequentially calculated according to the method, the formed whole block chain is marked as an nth +1 dimensional spatial block chain. The (n + 1) -th spatial block chain includes one or more (one in this example) nth spatial snapshot result block chains and an nth spatial snapshot object block chain, which can be used as each nth spatial block chain in the (n + 1) -th spatial block chain, respectively.
The irreversible algorithm may be a fixed-length computation (Hash) algorithm, and correspondingly, the character string obtained by the irreversible algorithm may be a Hash value.
When the block head data of each block in each nth dimensional space snapshot result block chain is formed, other control data possibly existing in the block head data is ignored, and if the control data exists in the block head of the block, the control data and the calculated hash value can be used as the block head data of the current block.
In the method for generating a central multidimensional expanded block chain provided in the embodiment of the present invention, one or more nth dimensional spatial snapshot result block chains are generated by performing data snapshot on a currently formed nth dimensional spatial block chain, where the nth dimensional spatial snapshot result block chain is marked as an nth dimensional spatial snapshot object block chain, a first link relationship between each block in the nth dimensional spatial snapshot result block chain and each block in the nth dimensional spatial snapshot object block chain is the same, and the contents of block data in the blocks are correspondingly the same; the nth dimension space block chain comprises a plurality of nth-1 dimension space block chains with a link relation; taking each block in the nth dimensional spatial snapshot object block chain as a parent block, taking each block in the nth dimensional spatial snapshot result block chain corresponding to each parent block as a child block, and performing combined linking on the nth dimensional spatial snapshot object block chain and the nth dimensional spatial snapshot result block chain to form a second linking relation; and sequentially generating a hash value of each block in the one or more nth dimensional spatial snapshot result block chains according to the first link relation and the second link relation, and writing the hash value into a block header of each corresponding block to form an nth +1 dimensional spatial block chain, wherein the one or more nth dimensional spatial snapshot result block chains and the nth dimensional spatial snapshot object block chain are respectively used as the nth dimensional spatial block chains in the nth +1 dimensional spatial block chain, so that an expansion process from the nth dimensional spatial block chain to the nth +1 dimensional spatial block chain is completed. The expanded n + 1-dimensional space block chain can meet the requirements of organizing and managing diversified data.
Example two
Fig. 8 is a flowchart of a second method for generating a block chain of a central multidimensional extension according to an embodiment of the present invention, where the embodiment of the method may be regarded as a refinement method of the embodiment of the method shown in fig. 4. As shown in fig. 8, the block chain generating method includes the following steps:
s810, performing data snapshot on a currently formed nth dimensional space block chain, and generating one or more nth dimensional space snapshot result block chains corresponding to the nth dimensional space block chain, wherein the original nth dimensional space block chain is marked as an nth dimensional space snapshot object block chain, the nth dimensional space snapshot result block chain and a first link relation among blocks in the nth dimensional space snapshot object block chain are the same, and the contents of block data in the blocks are correspondingly the same; the nth dimension space block chain comprises a plurality of nth-1 dimension space block chains with a link relation; step S810 is similar to step S410.
Specifically, fig. 9 shows a specific method of data snapshot, where the block header data of each block of the block chain of the nth dimensional spatial snapshot result generated according to the method is empty. As shown in fig. 9, the method for data snapshot includes the following steps:
s910, copying block data of each block in the nth dimensional space snapshot object block chain and a first link relation among the blocks, and building one or more same block chain architectures according to copied contents;
for example, taking the nth dimensional space snapshot object block chain shown in fig. 5 as an example, block volume data in a block a and a block B and a first link relationship are copied, the copied block volume data is used to construct a block without block header data, and then the blocks are constructed into a block chain architecture according to the first link relationship.
And S920, adding label information aiming at the current data snapshot into the block head of each block in each established block chain structure so as to form each nth dimensional space snapshot result block chain.
The tag information may include time information for the current data snapshot, storage location information of the block, and the like.
As shown in fig. 10, two identical blockchain architectures built according to the above steps are shown, where the blockbody data of each block in the blockchain architecture 1 and the blockchain architecture 2 is the same as the blockbody data of each block in the block chain of the nth dimensional spatial snapshot object, and the tag information for the current data snapshot is added to the block header data, and the tag information in the block header of each block may be the same or different.
And S820, modifying block volume data of blocks in one or more nth dimensional space snapshot result block chains and/or link relations among the blocks.
In order to meet the modification requirement of the block volume data of the blocks in each nth dimensional spatial snapshot result block chain and the requirement of adjusting the link organization form of each block in the block chain in practical application, the block volume data of the blocks in one or more nth dimensional spatial snapshot result block chains and/or the link relationship among the blocks can be modified after the data snapshot.
Specifically, modifying block volume data of blocks in one or more nth dimensional spatial snapshot result block chains comprises:
at least one of adding, deleting and replacing the contents of the block volume data.
For example, fig. 11 shows a schematic diagram of operations for modifying the block volume data, such as a delete operation of data 1 in the block volume data, an add operation of data 3 to the block volume data, and a replace operation of replacing data 2 with data 2'.
Specifically, modifying the link relationship between blocks in one or more nth dimensional spatial snapshot result block chains comprises:
the link relationship between the blocks is exchanged,
and/or the presence of a gas in the gas,
after one or more blocks are deleted and/or added, the link relation between the blocks is newly formed.
The swapping of the link relationship between the blocks means that the link relationship between the existing blocks is adjusted without adding or deleting the blocks in the block chain. For example, as shown in fig. 12, the tree-link relationship formed by the block a as the parent block and the blocks B and C as the child blocks is adjusted to a single-chain link relationship formed by the block a as the parent block of the block B and the block B as the parent block of the block C.
The step of forming the link relationship between the blocks from the new state after deleting and/or adding one or more blocks means that in the currently formed block chain, one or more blocks are deleted and/or added first, and then the link relationship between the blocks is formed from the new state as required. For example, in the block chain of the tree-link relationship shown in fig. 13, which is configured with the block a as a parent block and the blocks B and C as children blocks, the block D is added and the block B is deleted, and then the block D is linked after the block a as required, so as to form a new block chain of the tree-link relationship.
S830, taking each block in the nth dimensional spatial snapshot object block chain as a parent block, taking each block in the nth dimensional spatial snapshot result block chain corresponding to each parent block as a child block, and performing combined linking on the nth dimensional spatial snapshot object block chain and the nth dimensional spatial snapshot result block chain to form a second linking relation; step S830 is similar to step S420.
Specifically, after modifying the block volume data of the blocks and/or the link relationship between the blocks in one or more nth dimensional spatial snapshot result block chains formed by the data snapshot, the following definitions are provided for each block in the nth dimensional spatial snapshot result block chain:
the block after modifying the block volume data of the block still maintains the corresponding relation with the original corresponding block in the nth dimensional space snapshot object block chain;
after the link relation among the blocks is exchanged, the corresponding blocks still keep the corresponding relation with the original corresponding blocks in the nth dimensional space snapshot object block chain;
the added blocks do not have corresponding blocks in the nth dimensional spatial snapshot object block chain.
And S840, sequentially generating hash values of the blocks in the nth dimensional spatial snapshot result block chain according to the first link relation and the second link relation, and writing the hash values into the block headers of the corresponding blocks to form an nth +1 dimensional spatial block chain, wherein each nth dimensional spatial snapshot result block chain and each nth dimensional spatial snapshot object block chain are respectively used as each nth dimensional spatial block chain in the nth +1 dimensional spatial block chain. Step S840 is the same as step S430.
And S850, performing block chain extension along one or more nth dimensional space block chains in each nth dimensional space block chain in the (n + 1) th dimensional space block chains.
After the current nth dimensional space block chain is subjected to dimension expansion each time to form an nth +1 dimensional space block chain, the block chains can still be expanded in the nth +1 dimensional space block chain along one or more nth dimensional space block chains in each nth dimensional space block chain in the nth +1 dimensional space block chain.
For example, fig. 14 shows a comprehensive change form diagram in which the entire dimension of the blockchain is expanded and the dimension of each entire dimension is expanded. As shown in the figure, the morphology of the block chain in 4 states is shown:
first dimension space block chain state 1: the state is an initial state of the block chain, the diagram only includes a block chain state of a block a, certainly, in the first dimension space, the current block chain can be extended in the dimension, and the extended block chain is still in the first dimension space;
second dimension space block chain state 1: in this state, the block chain has been raised from the original one-dimensional space to a two-dimensional space, and the block chain is extended in the two-dimensional space within the dimension; specifically, data snapshot is performed on a first-dimension space block chain formed by the block a to obtain a snapshot result block chain formed by the block a1, and then the block a1 is linked to the block a to complete the one-dimension to two-dimension ascending process of the block chain; and then, continuing extending in the dimension on the current second dimension space block chain by taking the snapshot object block chain as an extension object to generate a block B.
Second dimension space block chain state 2: in this state, the blockchain is only subjected to dimension extension in a two-dimensional space, including taking a data snapshot on the blockchain formed by the block a and the block B to obtain a snapshot result blockchain formed by the block a2 and the block B1, and then linking the blockchain to the corresponding snapshot object blockchain; and then, continuing to perform dimension extension in the two-dimensional space on the current second-dimension space block chain by taking the snapshot object block chain as an extension object to generate a block C and a block D.
Third dimension space block chain state 1: in this state, the block chain has been raised from the original two-dimensional space to a three-dimensional space; specifically, data snapshot is performed on the whole block chain in the second-dimension space block chain state 2 to obtain a corresponding snapshot result block chain, and then the snapshot result block chain is linked with the snapshot object block chain to complete the dimension increasing process of the block chain from two-dimension to three-dimension.
Third dimension space block chain state 2: and in the third dimension space block chain, continuing to perform dimension extension in the three-dimensional space by taking the snapshot object block chain as an extension object to generate a block E.
It is to be noted that the concept of the dimensional space in the embodiment of the present invention is slightly different from the dimensional space in the space geometry, and the dimensional space in the conventional space geometry is an N-dimensional space composed of an infinite number of N-1-dimensional spaces. For example, a line is composed of numerous points, a surface is composed of numerous lines, and a body is composed of numerous surfaces. Whereas the N-dimensional space in the present embodiment is composed of a finite number of N-1-dimensional spaces. For example, the second-dimensional spatial blockchain may be composed of a plurality of first-dimensional spatial blockchains that are linked to each other, the third-dimensional spatial blockchain may be composed of a plurality of second-dimensional spatial blockchains that are linked to each other, and so on.
The method for generating the central multidimensional expanded block chain in the embodiment of the invention is characterized in that on the basis of the first embodiment, a data snapshot process of an nth dimensional space block chain is explained in detail; after the data snapshot is completed, modifying block data and/or a link relation between blocks of the block chain of the obtained nth dimensional space snapshot result block chain so as to meet an expansion requirement that the block chain needs to be modified in a dimension expansion process, and further meet a more complex organization requirement for the block data.
