Based on this, for the deficiency that existing block chain technology is applied in art work field, the embodiment of the present invention provides one kind
The modification of block chain block, following will be combined with the drawings in the embodiments of the present invention, to the technical side in the embodiment of the present invention
Case is clearly and completely described, it is clear that described embodiments are some of the embodiments of the present invention, rather than whole realities
Apply example.Based on the embodiments of the present invention, those of ordinary skill in the art are obtained without creative efforts
Every other embodiment, shall fall within the protection scope of the present invention.
It is one of the flow diagram of amending method of block chain block provided in an embodiment of the present invention referring to Fig. 1, Fig. 1,
As shown in Figure 1, comprising the following steps:
Step 101, the first block chain node relevant to Item Value equity is obtained to send based on target block chain block
Modification request；
The amending method of block chain block provided in an embodiment of the present invention is mainly used in the Item Value based on block chain
On share system, the article can for the art work, antique or it is other can be with the article of shareable value, following embodiment will be with
It is described in detail for the art work.
Both parties can be traded in a manner of intelligent contract art on the Item Value share system based on block chain
Product, to sell its value.Intelligent contract is a kind of computer association for being intended to propagate, verify or execute in a manner of information-based contract
View is responsible for that the service logic in block catenary system is realized, compiles and disposed in the form of code, completes the condition of established rule
Triggering and automatic execution, reduce manual intervention to greatest extent.
The operation object of intelligent contract is mostly digital asset, and permission carries out credible friendship in no third-party situation
Easily, traceable after block chain in transaction and be difficult to modify, the embodiment of the present invention aims to solve the problem that block chain block was difficult to modify asks
Topic.
Firstly, introducing the usage scenario of the embodiment of the present invention, if a certain art work A, multiple users possess the art simultaneously
The value of product A, that is to say, that possess the value equity share of art work A, these users can correspond to a block chain link
Point, these users can initiate to modify to the content of a certain target block chain block by block chain node.
It is above-mentioned it is related to Item Value equity can be understood as possessing Item Value equity share, such as occupy art work A valence
It is worth equity share 6%.It include essential information relevant to the article and Transaction Information in above-mentioned target block chain block.When with
When the triggering modification button of family, the first block chain node corresponding with the user can automatically generate corresponding modification request, and
Modification request is sent, is modified with request to target block chain block.It is asked correspondingly, system obtains the modification by monitoring
It asks.
System can be monitored in real time, and each block chain node of preset time periodic monitor can also be spaced, in block chain
System can obtain in time when node sends modification request.
The modification request may include the address information of target block chain block, the i.e. hash of target block chain block
Value can also include modification content.
Step 102, communication request being sent to the second block chain node, the communication request includes the modification request,
The second block chain node is block chains relevant with the Item Value equity different to the first block chain node
Node；
The communication request includes the modification request, and communication request is sent to the secondth area by the first block chain node
Block chain node, it is therefore an objective to be communicated with the foundation of the second block chain node, be based on the modification to obtain each second block chain node
The reply of request.
Step 103, the statement information that third block chain node is sent based on the modification request, the third block are obtained
Chain node is to establish the second block chain node communicated with the first block chain node based on communication request；
After receiving communication request, the second block chain node can be regardless of the corresponding group of the first block chain node
Why is group grade, directly communicates with the foundation of the first block chain node, sends statement information to the second block chain node.Certainly, it is
The layer management for establishing communication, more efficiently completes the modification to target block chain block, the second block chain
Node is also predefined whether the first block chain node has reached its communicating requirement, if having reached its communicating requirement, just with the firstth area
Block chain link point is communicated, and specific implementation process elaborates embodiment below.
It should be noted that the second block chain node communicated is only established with the first block chain node, that is,
It says, only third block chain node just can send statement information based on modification request.
The statement information can be there are two types of situation, and one is agreement modification is shown, another kind is to show to disagree modification.
Certainly, the statement information can also carry additional information, such as carry and only agree to which part of modification or refusal modify which portion
Point etc..
Step 104, the statement information obtained in statistics preset time shows to agree to the third block chain node of modification
The corresponding Item Value equity share；
Above-mentioned preset time can be configured according to actual needs, if modification does not influence the Item Value and transaction
Preset time can be arranged the longer time that compares, such as one month, otherwise, preset time is arranged by unimportant content
Relatively short time, such as one day.
The statement information of third block chain node is persistently obtained within a preset time, and is obtained the statement information and shown together
The third block chain node of meaning modification, statistics show to agree to the corresponding Item Value equity of third block chain node of modification
Share.
Step 105, if the specific gravity that the Item Value equity share accounts for total equity share is greater than preset threshold, to the mesh
Mark block chain block is modified.
The preset threshold can be configured according to actual needs, such as be arranged to 5%, 10%, following embodiment, institute
Stating preset threshold will be described in detail for 50%.
In addition, not appointing if the Item Value equity share accounts for the specific gravity of total equity share no more than preset threshold
Where reason, i.e., do not modify to the content of target block chain block.
For example for, user M1, user M2 and user M3 et al. are achieved by way of encrypting moneytary operations
The ownership of one rare paintings, and be worth and shared by block catenary system and several external collectors, these collections
Family achieves the part value of this width famous painting after completing transaction procedure respectively.
At the beginning of the block catenary system is established, according to the information that this width famous painting seller provides, set in gained block catenary system
There is a block chain block, describes this width famous painting once in 1963, changed hands by user M4 and be sold to user M5.When having crossed one section
Between, the user M6 of a certain block chain node obtains extremely exact evidence, and the buyer for sufficiently demonstrating above-mentioned transaction is not to use
Family M5 is the hidden buyer of another one: user M7 in fact.
Then, user M6 in block catenary system by using block chain node initiate in target block chain block
The request that Transaction Information is modified has obtained the statement letter for showing to agree to modification of several block chain nodes within a preset time
Breath.These corresponding equity shares of block chain node of system-computed, counting the specific gravity for obtaining accounting for total equity share has been more than 70%,
Greater than pre-set threshold value 50%, then, modify to the target block chain block.
The embodiment of the present invention is based on target block chain by obtaining the first block chain node relevant to Item Value equity
The modification request that block is sent；Communication request is sent to the second block chain node, the communication request includes that the modification is asked
It asks, the second block chain node is blocks relevant with the Item Value equity different to the first block chain node
Chain node；The statement information that third block chain node is sent based on the modification request is obtained, the third block chain node is
The the second block chain node communicated is established with the first block chain node based on communication request；Count acquisition in preset time
The statement information shows to agree to the corresponding Item Value equity share of third block chain node of modification；If the article
The specific gravity that value equity share accounts for total equity share is greater than preset threshold, modifies to the target block chain block.To
It can modify to information in block chain block, guarantee the accuracy and validity that store information in block chain.
Further, not all block chain block can modify, if the content of modification has influenced area
The corresponding Item Value equity share of block chain node, then this partial content does not allow to be modified.
Fig. 2 is the two of the flow diagram of the amending method of block chain block provided in an embodiment of the present invention, such as Fig. 2 institute
Show, comprising the following steps:
Step 201, the first block chain node relevant to Item Value equity is obtained to send based on target block chain block
Modification request；
Step 202, the block attributes of the target block chain block are determined；
There are two types of block attributes for the block chain block, and, for that can modify block, another is that can not modify area for the first
Block.The block attributes can be determined when block chain block generates, and can mark its block chain by the means of simulation modification
The block attributes of block.
Mark the specific steps of the block attributes of its block chain block: firstly, carrying out mould to newly-generated block chain block
Quasi- modification, determines the Item Value equity share of each block chain node after modification；Next, it is determined whether there is block chain node
Item Value equity share changes, if so, be then labeled as the block attributes of the block chain block to modify block, if
The block attributes of the block chain block are then labeled as that block can be modified by nothing；Finally, the hash value of the block chain block is set
For fixed value, when ensuring that the Transaction Information of the block chain block changes, adjacent block chain block is not influenced.
Step 203, if the block attributes show that the target block chain block is that can modify block, communication request is sent out
Give the second block chain node, the communication request includes the modification request, and the second block chain node is and described the
The different block chain nodes relevant to the Item Value equity of one block chain node；
If the block attributes show that the target block chain block is that can not modify block, terminate the process of modification.
Step 204, the statement information that third block chain node is sent based on the modification request, the third block are obtained
Chain node is to establish the second block chain node communicated with the first block chain node based on communication request；
Step 205, the statement information obtained in statistics preset time shows to agree to the third block chain node of modification
The corresponding Item Value equity share；
Step 206, if the specific gravity that the Item Value equity share accounts for total equity share is greater than preset threshold, to the mesh
Mark block chain block is modified.
For example for, user M1, user M2 and user M3 et al. are achieved by way of encrypting moneytary operations
The ownership of one rare paintings, and be worth and shared by block catenary system and several external collectors, these collections
Family achieves the part value of this width famous painting after completing transaction procedure respectively.
At the beginning of the block catenary system is established, according to the information that this width famous painting seller provides, set in gained block catenary system
There is a block chain block, describes this width famous painting once in 1963, changed hands by user M4 and be sold to user M5, transaction amount is
50000 yuan.Block catenary system carries out simulation modification to the block chain block, and the relationship trading amount of money is revised as 100,000 yuan, is as a result shown
Show and the Item Value equity share of all block chain nodes is not had an impact, therefore by the block attributes mark of the block chain block
Block can be modified by being denoted as, and the cryptographic Hash in the block chain block is set as fixed value.
A period of time is spent, the user M6 of a certain block chain node obtains extremely exact evidence, sufficiently demonstrates above-mentioned
The buyer of transaction is not user M5, is the hidden buyer of another one: user M7 in fact.
Then, user M6 in block catenary system by using block chain node initiate in target block chain block
The request that Transaction Information is modified has obtained the statement letter for showing to agree to modification of several block chain nodes within a preset time
Breath.These corresponding equity shares of block chain node of system-computed, counting the specific gravity for obtaining accounting for total equity share has been more than 70%,
Greater than pre-set threshold value 50%, then, modify to the target block chain block.
Through the embodiment of the present invention, the modification due to block chain block can be avoided to a certain extent and influences article
The value equity share possessed, to influence the actual benefit that article possesses.
It certainly, is not that the All Activity information of revisable block chain block can modify, if modification is interior
Appearance has influenced the corresponding Item Value equity share of block chain node, then this partial content does not allow to be modified.Therefore, in order to
Guarantee related amendments, material alterations will not be generated to the Item Value equity share that each block chain node is enjoyed, be provided with
Simulation modification is first carried out, then completes the safeguard mean of substantial modifications.
Specifically, Fig. 3 is the three of the flow diagram of the amending method of block chain block provided in an embodiment of the present invention, such as
Shown in Fig. 3, comprising the following steps:
Step 301, the first block chain node relevant to Item Value equity is obtained to send based on target block chain block
Modification request；
Step 302, the block attributes of the target block chain block are determined；
There are two types of block attributes for the block chain block, and, for that can modify block, another is that can not modify area for the first
Block.The block attributes can be determined when block chain block generates, and can mark its block chain by the means of simulation modification
The block attributes of block.
Mark the specific steps of the block attributes of its block chain block: firstly, carrying out mould to newly-generated block chain block
Quasi- modification, determines the Item Value equity share of each block chain node after modification；Next, it is determined whether there is block chain node
Item Value equity share changes, if so, be then labeled as the block attributes of the block chain block to modify block, if
The block attributes of the block chain block are then labeled as that block can be modified by nothing；Finally, the hash value of the block chain block is set
For fixed value, when ensuring that the Transaction Information of the block chain block changes, adjacent block chain block is not influenced.
Step 303, if the block attributes show that the target block chain block is that can modify block, communication request is sent out
Give the second block chain node, the communication request includes the modification request, and the second block chain node is and described the
The different block chain nodes relevant to the Item Value equity of one block chain node；
If the block attributes show that the target block chain block is that can not modify block, terminate the process of modification.
Step 304, the statement information that third block chain node is sent based on the modification request, the third block are obtained
Chain node is to establish the second block chain node communicated with the first block chain node based on communication request；
Step 305, the statement information obtained in statistics preset time shows to agree to the third block chain node of modification
The corresponding Item Value equity share；
Step 306, if the specific gravity that the Item Value equity share accounts for total equity share is greater than preset threshold,
Simulation modification is carried out to the target block chain block；
Step 307, the corresponding object of relevant to the Item Value equity all block chain nodes is determined
Whether product value equity share changes；
Step 308, it if all not changing, modifies to the target block chain block.
For example for, user M1, user M2 and user M3 et al. are achieved by way of encrypting moneytary operations
The ownership of one rare paintings, and be worth and shared by block catenary system and several external collectors, these collections
Family achieves the part value of this width famous painting after completing transaction procedure respectively.
At the beginning of the block catenary system is established, according to the information that this width famous painting seller provides, set in gained block catenary system
There is a block chain block, describes this width famous painting once in 1963, changed hands by user M4 and be sold to user M5, transaction amount is
50000 yuan.Block catenary system carries out simulation modification to the block chain block, and the relationship trading amount of money is revised as 100,000 yuan, is as a result shown
Show and the Item Value equity share of all block chain nodes is not had an impact, therefore by the block attributes mark of the block chain block
Block can be modified by being denoted as, and the cryptographic Hash in the block chain block is set as fixed value.
A period of time is spent, the user M6 of a certain block chain node obtains extremely exact evidence, sufficiently demonstrates above-mentioned
The buyer of transaction is not user M5, is the hidden buyer of another one: user M7 in fact.
Then, user M6 in block catenary system by using block chain node initiate in target block chain block
The request that Transaction Information is modified has obtained the statement letter for showing to agree to modification of several block chain nodes within a preset time
Breath.These corresponding equity shares of block chain node of system-computed, counting the specific gravity for obtaining accounting for total equity share has been more than 70%,
Greater than pre-set threshold value 50%；Then, simulation modification is carried out to the target block chain block, determines all block chain links
Whether the corresponding value equity share of point changes；Finally, if all not changing, to the target block chain block into
Row modification, if the corresponding value equity share of an at least block chain node changes, without any subsequent operation.
It should be noted that simulation modification described in above embodiments is that system is repaired to what block chain block was simulated
Change, substantial modification can't be carried out to any content of block chain block, that is to say, that the corresponding any terminal of block chain node
On all still show original information.
The embodiment of the present invention first carries out simulation modification by setting, then completes the safeguard mean of substantial modifications, Neng Goubao
Related amendments are demonstrate,proved, material alterations will not be generated to the Item Value equity share that each block chain node is enjoyed.
In order to realize the communication between each block chain node in block catenary system, more efficiently complete to target area
The modification of block chain block, the present embodiment devise a kind of communication equipment based on group's grade between each block chain node
System.
Specifically, Fig. 4 is the four of the flow diagram of the amending method of block chain block provided in an embodiment of the present invention, such as
Shown in Fig. 4, comprising the following steps:
Step 401, the first block chain node relevant to Item Value equity is obtained to send based on target block chain block
Modification request；
Step 402, the block attributes of the target block chain block are determined；
There are two types of block attributes for the block chain block, and, for that can modify block, another is that can not modify area for the first
Block.The block attributes can be determined when block chain block generates, and can mark its block chain by the means of simulation modification
The block attributes of block.
Mark the specific steps of the block attributes of its block chain block: firstly, carrying out mould to newly-generated block chain block
Quasi- modification, determines the Item Value equity share of each block chain node after modification；Next, it is determined whether there is block chain node
Item Value equity share changes, if so, be then labeled as the block attributes of the block chain block to modify block, if
The block attributes of the block chain block are then labeled as that block can be modified by nothing；Finally, the hash value of the block chain block is set
For fixed value, when ensuring that the Transaction Information of the block chain block changes, adjacent block chain block is not influenced.
Step 403, if the block attributes show that the target block chain block is that can modify block, communication request is sent out
Give the second block chain node, the communication request includes the modification request, and the second block chain node is and described the
The different block chain nodes relevant to the Item Value equity of one block chain node；
If the block attributes show that the target block chain block is that can not modify block, terminate the process of modification.
Step 404, determine whether block chain node group reaches and the second block chain node based on the communication request
Communicating requirement；
If the first block chain node reaches the communicating requirement with the second block chain node, the block chain node
Group includes the first block chain node, if the first block chain node is not up to the communication with the second block chain node
It is required that the block chain node group includes the first block chain node and has sent statement information and the statement information shows
Agree to the third block chain node of modification；
It is possible, firstly, to, by all block chain nodes, be divided into several differences etc. according to the difference of Item Value equity share
The group of grade, i.e., each block chain node correspond to group's grade.Such as: by Item Value equity share greater than 10%
The block chain node that block chain node is included into advanced group, Item Value equity share is between 1% -10% is included into intermediate group
The block chain node of group, Item Value equity share less than 1% is included into rudimentary group.
Then, default: 1) the block chain node in the same group can directly carry out point-to-point communication；
2) the block chain node in higher level group can directly carry out point-to-point with the block chain node in lower grade group
Communication；3) when the block chain node needs in lower grade group are communicated with the block chain link point in higher level group,
The block chain node in sufficient amount of same group must be gathered first, composition one reaches needed for related higher level group
Item Value equity share block chain node group, be just able to achieve in higher level group block chain link point carry out it is multipair
One communication.
After the completion of default, the step 404 includes:
Based on the communication request, the corresponding Item Value equity share of block chain node group is obtained；
If group's grade of the block chain node group is lower than the corresponding group's grade of the second block chain node, determine
The block chain node group is not up to the communicating requirement with the second block chain node；Group's grade is based on block chain
Determined by the corresponding Item Value equity share of node；
Otherwise, it determines the block chain node group reaches the communicating requirement with the second block chain node.
It should be noted that system is all at the beginning of the first block chain node is communicated with the foundation of all second block chain nodes
Group's grade or corresponding lower than group's grade of the first block chain node suitable with the first block chain node can directly be matched
Second block chain link point carries out point-to-point communication, and the block chain node group only includes the first block chain node.When matching not
To suitable group's grade the second block chain node when, system can by the first block chain node with sent statement information and described
Statement information shows to agree to that the third block chain link point of modification is combined, forms a block chain node group, make up to more
High group's grade, in this manner it is possible to which the second block chain link point with Geng Gao group grade communicate.In block chain node group
When being communicated with the second block chain link point of Geng Gao group grade, the first block chain node and the second block chain link can be authorized
Point is communicated, specifically, may include each area in block chain node group in the communication request that the first block chain node is sent
The corresponding Item Value equity share of block chain node.
Whether agree to target block it is understood that the communication can help to reach between each block chain node
The common recognition that chain block is modified.
Step 405, if the block chain node group reaches the communicating requirement with the second block chain node, by described
One block chain node is communicated with the second block chain node foundation, obtains third block chain node；
Step 406, the statement information that third block chain node is sent based on the modification request, the third block are obtained
Chain node is to establish the second block chain node communicated with the first block chain node based on communication request；
Step 407, the statement information obtained in statistics preset time shows to agree to the third block chain node of modification
The corresponding Item Value equity share；
Step 408, if the specific gravity that the Item Value equity share accounts for total equity share is greater than preset threshold,
Simulation modification is carried out to the target block chain block；
Step 409, the corresponding object of relevant to the Item Value equity all block chain nodes is determined
Whether product value equity share changes；
Step 410, it if all not changing, modifies to the target block chain block.
For example for, user M1, user M2 and user M3 et al. are achieved by way of encrypting moneytary operations
The ownership of one rare paintings, and be worth and shared by block catenary system and several external collectors, these collections
Family achieves the part value of this width famous painting after completing transaction procedure respectively.
At the beginning of the block catenary system is established, according to the information that this width famous painting seller provides, set in gained block catenary system
There is a block chain block, describes this width famous painting once in 1963, changed hands by user M4 and be sold to user M5, transaction amount is
50000 yuan.Block catenary system carries out simulation modification to the block chain block, and the relationship trading amount of money is revised as 100,000 yuan, is as a result shown
Show and the Item Value equity share of all block chain nodes is not had an impact, therefore by the block attributes mark of the block chain block
Block can be modified by being denoted as, and the cryptographic Hash in the block chain block is set as fixed value.
A period of time is spent, the user M6 of a certain block chain node obtains extremely exact evidence, sufficiently demonstrates above-mentioned
The buyer of transaction is not user M5, is the hidden buyer of another one: user M7 in fact.
Then, user M6 in block catenary system by using block chain node initiate in target block chain block
The request that Transaction Information is modified, due to user M6 it is owned paintings value equity share there was only 0.6%, cannot with gather around
There is the block chain link point of paintings value equity share to carry out direct communication, therefore, user M6 is first and in same group's grade
Block chain node (i.e. paintings value equity share be less than 1% block chain node) communicate one by one, obtain enough blocks
After the agreement of chain node, one block chain node group comprising 15 block chain nodes of composition, the block chain node group is corresponded to
Paintings value equity share summation be greater than 10%.Then, in the form of many-to-one, the block chain with a certain intermediate group is realized
The communication of node, and same method is used, the final communication realized with the block chain node of highest level group.
After establishing communication, the statement letter for showing to agree to modification of several block chain nodes has been obtained in preset time
Breath.These corresponding equity shares of block chain node of system-computed, counting the specific gravity for obtaining accounting for total equity share has been more than 70%,
Greater than pre-set threshold value 50%；Then, simulation modification is carried out to the target block chain block, determines all block chain links
Whether the corresponding value equity share of point changes；Finally, if all not changing, to the target block chain block into
Row modification, if the corresponding value equity share of an at least block chain node changes, without any subsequent operation.
It should be noted that simulation modification described in above embodiments is that system is repaired to what block chain block was simulated
Change, substantial modification can't be carried out to any content of block chain block, that is to say, that the corresponding any terminal of block chain node
On all still show original information.
