Detailed Description
In 2018, with the rise of the block chain, various industries are changed differently, and the block chain is not exceptional in the art industry. Many art organizations have expanded a large number of blockchain application experiments and have caused considerable shock in the industry, where blockchains have made extraordinary progress in expanding the transparency of the art industry market, tracking ownership, and going out. Moreover, if the block chain is fused with the artwork industry, the circulation of the artwork and the reflection of the financial value of the artwork can reach the recognition of global consensus.
The core nature of the blockchain: DLT is an encrypted distributed accounting technology, and the natural attributes of the blockchain technology enable each artwork transaction to have traceability, so that verification of identity credit of buyers and sellers, unique certificate for the target artwork and artwork comprehensive insurance service in the offline logistics transportation process can be ensured to be efficiently and safely carried out in the whole transaction process through blockchain application.
Although blockchains can track the origination of the work of art, blockchain blocks are not allowed to be modified after generation and any erroneous entry into the ledger is not allowed to be modified due to the closeness of the origination tracking on the blockchain, thus, permanent inaccuracies may remain with respect to the work of art while limiting the possibility of auditing and correcting over time.
Based on this, in order to overcome the defects of the application of the prior blockchain technology in the art field, the embodiment of the present invention provides a modification scheme of blockchain blocks, and the technical scheme in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for modifying a blockchain block according to an embodiment of the present invention, as shown in fig. 1, including the following steps:
the modification method of the blockchain block provided by the embodiment of the invention is mainly applied to an article value sharing system based on the blockchain, wherein the article can be an artwork, an antique or other articles capable of sharing value, and the following embodiment will take the artwork as an example for detailed description.
The two parties of the transaction can trade the artwork in an intelligent contract mode on the article value sharing system based on the blockchain so as to sell the value of the artwork. The intelligent contract is a computer protocol aiming at propagating, verifying or executing the contract in an informatization mode, and is responsible for realizing, compiling and deploying business logic in a blockchain system in a code mode, completing condition triggering and automatic execution of established rules and reducing manual intervention to the maximum extent.
The method and the device aim to solve the problem that a blockchain block is difficult to modify.
First, a usage scenario of the embodiment of the present invention is introduced, where a certain artwork a is set, a plurality of users simultaneously have a value of the artwork a, that is, have a value equity share of the artwork a, the users may all correspond to a block chain node, and the users may initiate to modify the content of a target block chain block through the block chain node.
The above relation to the property value equity can be understood as having a property value equity share, such as 6% of the value equity share of the artwork A. The target blockchain block comprises basic information and transaction information related to the article. When a user triggers a modification button, the first block link point corresponding to the user may automatically generate a corresponding modification request and send the modification request to request modification of the target block chain block. Accordingly, the system obtains the modification request through monitoring.
The system can monitor in real time, and can also monitor each block chain node at intervals of preset time at regular time, so that the system can acquire the nodes in time when the block chain nodes send modification requests.
The modification request may include address information of the target blockchain block, that is, a hash value of the target blockchain block, and may further include modification content.
the communication request comprises the modification request, the first block link node sends the communication request to the second block link nodes in order to establish communication with the second block link nodes to obtain replies of the respective second block link nodes based on the modification request.
103, acquiring the table information sent by a third block chain node based on the modification request, wherein the third block chain node is a second block chain node establishing communication with the first block chain node based on the communication request;
after receiving the communication request, the second block link point may directly establish communication with the first block link point regardless of the group level corresponding to the first block link point, and send the form information to the second block link node. Of course, in order to establish hierarchical management of communication and complete modification of the target block chain block more effectively, the second block chain node further determines whether the first block chain node has reached its share requirement, and only communicates with the first block chain node if the first block chain node has reached its share requirement, and the specific implementation process thereof will be described in detail in the following embodiments.
It should be noted that only the second blockchain node, i.e. only the third blockchain node, establishing communication with the first blockchain node may send the formal information based on the modification request.
The formal information may be used in two cases, one indicating agreement with the modification and the other indicating disagreement with the modification. Of course, the formal information may also carry additional information, such as carrying which part only agrees to modify or which part is denied to modify, etc.
the preset time can be set according to actual needs, if the irrelevant contents which do not affect the value of the article and the transaction are modified, the preset time can be set to be relatively long time, such as one month, otherwise, the preset time can be set to be relatively short time, such as one day.
And continuously acquiring the form information of the third block chain node within preset time, acquiring the third block chain node indicating that modification is allowed according to the form information, and counting the commodity value equity share corresponding to the third block chain node indicating that modification is allowed.
And 105, if the proportion of the item value equity shares in the total equity shares is greater than a preset threshold value, modifying the target block chain block.
The preset threshold may be set according to actual needs, such as 5%, 10%, and the like, and in the following embodiment, the preset threshold will be described in detail by taking 50% as an example.
In addition, if the proportion of the item value equity shares in the total equity shares is not greater than the preset threshold, no processing is performed, that is, the content of the target block chain block is not modified.
For example, user M1, user M2, user M3, etc. have taken ownership of a famous and precious painting by way of cryptocurrency transactions and shared its value with several outside collectors through the blockchain system, which have taken part of the value of the famous and precious painting after completing the transaction.
At the beginning of the creation of the blockchain system, a blockchain block is set in the blockchain system according to the information provided by the famous painting seller, and the famous painting is recorded to be handed over and sold to the user M5 by the user M4 in 1963. After a while, user M6 at a blockchain node gets very exact evidence, which is sufficient to prove that the buyer of the transaction is not user M5, but is another hidden buyer: user M7.
Next, the user M6 initiates a request for modification of the transaction information in the target blockchain block by using the blockchain node in the blockchain system, and obtains the formal information of the blockchain nodes indicating approval of modification within a preset time. The system calculates the corresponding equity shares of the block chain links, counts that the proportion of the equity shares in the total amount exceeds 70 percent and is greater than 50 percent of a preset threshold value, and then modifies the target block chain block.
The embodiment of the invention obtains a modification request sent by a first block chain link point related to the value right of an article based on a target block chain block; sending a communication request to a second blockchain node, the communication request including the modification request, the second blockchain node being a different blockchain point from the first blockchain node that is associated with the item value interest; acquiring the form information sent by a third block chain node based on the modification request, wherein the third block chain node is a second block chain node establishing communication with the first block chain node based on the communication request; counting the value and interest shares of the articles corresponding to the third block chain link points which are obtained within the preset time and indicate that modification is agreed; and if the proportion of the commodity value equity shares in the total equity shares is greater than a preset threshold value, modifying the target block chain block. Therefore, the information in the block chain block can be modified, and the accuracy and the effectiveness of the information stored in the block chain are ensured.
Further, not all blockchain blocks can be modified, and if the modified content affects the share of the value and interest of the goods corresponding to the blockchain link points, the modified content is not allowed to be modified.
Fig. 2 is a second flowchart of a block chain block modification method according to an embodiment of the present invention, as shown in fig. 2, including the following steps:
the blockchain block has two block attributes, the first is a modifiable block and the other is a non-modifiable block. The block attribute can be determined when the block chain block is generated, and the block attribute of the block chain block can be marked by simulating a modification means.
The specific steps of marking the block attribute of the block chain block are as follows: firstly, carrying out simulation modification on newly generated block chain blocks, and determining the commodity value equity shares of each block chain node after modification; then, judging whether the commodity value equity shares of the block chain nodes change or not, if so, marking the block attribute of the block chain block as a non-modifiable block, and if not, marking the block attribute of the block chain block as a modifiable block; finally, the hash value of the blockchain block is set as a fixed value so as to ensure that the transaction information of the blockchain block does not affect the adjacent blockchain block when changed.
and if the block attribute indicates that the target block chain block is an unmodified block, ending the modification process.
and step 206, if the proportion of the item value equity shares in the total equity shares is greater than a preset threshold, modifying the target block chain block.
For example, user M1, user M2, user M3, etc. have taken ownership of a famous and precious painting by way of cryptocurrency transactions and shared its value with several outside collectors through the blockchain system, which have taken part of the value of the famous and precious painting after completing the transaction.
At the beginning of the establishment of the block chain system, a block chain block is arranged in the obtained block chain system according to the information provided by the famous picture seller, the famous picture is recorded to be sold to a user M5 by a user M4 in 1963, and the transaction amount is 5 ten thousand yuan. The blockchain system carries out simulation modification on the blockchain block, modifies the related transaction amount to 10 ten thousand yuan, and as a result, the property right share of the goods value of all the blockchain nodes is not influenced, so that the block attribute of the blockchain block is marked as a modifiable block, and the hash value in the blockchain block is set to be a fixed value.
After a while, user M6 at a blockchain node gets very exact evidence, which is sufficient to prove that the buyer of the transaction is not user M5, but is another hidden buyer: user M7.
Next, the user M6 initiates a request for modification of the transaction information in the target blockchain block by using the blockchain node in the blockchain system, and obtains the formal information of the blockchain nodes indicating approval of modification within a preset time. The system calculates the corresponding equity shares of the block chain links, counts that the proportion of the equity shares in the total amount exceeds 70 percent and is greater than 50 percent of a preset threshold value, and then modifies the target block chain block.
By the embodiment of the invention, the influence on the value right share owned by the article due to the modification of the block chain block can be avoided to a certain extent, so that the actual benefit owned by the article is influenced.
Of course, not all transaction information of the modifiable blockchain block can be modified, and if the modified content affects the share of the value and interest of the article corresponding to the blockchain link point, the modified content is not allowed to be modified. Therefore, in order to ensure that the related modification does not generate substantial change on the share of the value and the right of the goods shared by the link points of each block, a guarantee means of firstly performing simulation modification and then completing the substantial modification is provided.
Specifically, fig. 3 is a third schematic flowchart of a modification method of a blockchain block according to an embodiment of the present invention, as shown in fig. 3, including the following steps:
the blockchain block has two block attributes, the first is a modifiable block and the other is a non-modifiable block. The block attribute can be determined when the block chain block is generated, and the block attribute of the block chain block can be marked by simulating a modification means.
The specific steps of marking the block attribute of the block chain block are as follows: firstly, carrying out simulation modification on newly generated block chain blocks, and determining the commodity value equity shares of each block chain node after modification; then, judging whether the commodity value equity shares of the block chain nodes change or not, if so, marking the block attribute of the block chain block as a non-modifiable block, and if not, marking the block attribute of the block chain block as a modifiable block; finally, the hash value of the blockchain block is set as a fixed value so as to ensure that the transaction information of the blockchain block does not affect the adjacent blockchain block when changed.
and if the block attribute indicates that the target block chain block is an unmodified block, ending the modification process.
in step 308, if no change occurs, the target blockchain block is modified.
For example, user M1, user M2, user M3, etc. have taken ownership of a famous and precious painting by way of cryptocurrency transactions and shared its value with several outside collectors through the blockchain system, which have taken part of the value of the famous and precious painting after completing the transaction.
At the beginning of the establishment of the block chain system, a block chain block is arranged in the obtained block chain system according to the information provided by the famous picture seller, the famous picture is recorded to be sold to a user M5 by a user M4 in 1963, and the transaction amount is 5 ten thousand yuan. The blockchain system carries out simulation modification on the blockchain block, modifies the related transaction amount to 10 ten thousand yuan, and as a result, the property right share of the goods value of all the blockchain nodes is not influenced, so that the block attribute of the blockchain block is marked as a modifiable block, and the hash value in the blockchain block is set to be a fixed value.
After a while, user M6 at a blockchain node gets very exact evidence, which is sufficient to prove that the buyer of the transaction is not user M5, but is another hidden buyer: user M7.
Next, the user M6 initiates a request for modification of the transaction information in the target blockchain block by using the blockchain node in the blockchain system, and obtains the formal information of the blockchain nodes indicating approval of modification within a preset time. The system calculates the corresponding equity shares of the block chain link points, and the calculated proportion of the equity shares in the total amount exceeds 70 percent and is greater than 50 percent of a preset threshold value; then, carrying out simulation modification on the target block chain block, and determining whether value right share corresponding to all block chain link points changes; and finally, if the target block chain block is not changed, modifying the target block chain block, and if the value right share corresponding to at least one block chain link point is changed, not performing any subsequent operation.
It should be noted that the simulation modification described in the above embodiment is a modification that the system simulates the blockchain block, and does not substantially modify any content of the blockchain block, that is, the original information is still displayed on any terminal corresponding to the blockchain block.
According to the embodiment of the invention, by setting a guarantee means of firstly carrying out simulation modification and then finishing substantial modification, relevant modification can be ensured, and the share of the value and the right of the goods shared by each block link point is not substantially changed.
In order to implement communication between each link node of the block chain in the block chain system and more effectively complete modification of the target block chain block, a communication mechanism based on group level is designed between each link node of the block chain in this embodiment.
Specifically, fig. 4 is a fourth flowchart of a modification method of a blockchain block according to an embodiment of the present invention, as shown in fig. 4, including the following steps:
the blockchain block has two block attributes, the first is a modifiable block and the other is a non-modifiable block. The block attribute can be determined when the block chain block is generated, and the block attribute of the block chain block can be marked by simulating a modification means.
The specific steps of marking the block attribute of the block chain block are as follows: firstly, carrying out simulation modification on newly generated block chain blocks, and determining the commodity value equity shares of each block chain node after modification; then, judging whether the commodity value equity shares of the block chain nodes change or not, if so, marking the block attribute of the block chain block as a non-modifiable block, and if not, marking the block attribute of the block chain block as a modifiable block; finally, the hash value of the blockchain block is set as a fixed value so as to ensure that the transaction information of the blockchain block does not affect the adjacent blockchain block when changed.
and if the block attribute indicates that the target block chain block is an unmodified block, ending the modification process.
if the first block link point meets the share requirement with the second block link node, the block link point group comprises the first block link node, and if the first block link point does not meet the share requirement with the second block link node, the block link point group comprises the first block link node and sent form information, and the form information indicates a third block link node which agrees to modification;
first, all the blockchain nodes can be divided into a plurality of groups with different levels according to different commodity value equity shares, that is, each blockchain node corresponds to one group level. For example: and (3) classifying the block link points with the commodity value equity share larger than 10% into a high-level group, classifying the block link points with the commodity value equity share between 1% and 10% into a medium-level group, and classifying the block link points with the commodity value equity share less than 1% into a low-level group.
Then, the system sets: 1) the block chain nodes in the same group can directly carry out point-to-point communication; 2) the block chain node points in the higher-level group can directly carry out point-to-point communication with the block chain node points in the lower-level group; 3) when a block link point in a lower-level group needs to communicate with a block link point in a higher-level group, a sufficient number of block link nodes in the same group must be collected to form a block link point group that achieves the share of the commodity value equity required by the relevant higher-level group, so that the many-to-one communication with the block link point in the higher-level group can be realized.
After the system setting is completed, step 404 includes:
based on the communication request, acquiring the share of the value and the interest of the article corresponding to the block link point group;
if the group level of the block chain node group is lower than the group level corresponding to the second block chain node point, determining that the block chain node group does not meet the share requirement of the second block chain node; the group rank is determined based on the item value equity shares corresponding to block link points;
otherwise, determining that the blockchain node group meets the share requirement with the second blockchain node.
It should be noted that, at the beginning of establishing communication between a first block link point and all second block link points, the system directly matches the second block link points corresponding to the group level equivalent to or lower than the group level of the first block link point for point-to-point communication, and the block link node group only includes the first block link node. When the second block chain nodes with the corresponding group level are not matched, the system combines the first block chain node with the third block chain node which has sent the form information and the form information indicates that the modification is approved to form a block chain node group, so that the block chain node group reaches the higher group level, and the communication with the second block chain node with the higher group level can be realized. When the block link point group communicates with a second block link point of a higher group level, the first block link point may be authorized to communicate with the second block link point, and specifically, the communication request sent by the first block chain node may include an item value right share corresponding to each block link point in the block chain node group.
It will be appreciated that the communication may help to achieve a consensus between the various block link points whether or not modifications to the target block chain block are agreed to.
in step 410, if no change occurs, the target blockchain block is modified.
For example, user M1, user M2, user M3, etc. have taken ownership of a famous and precious painting by way of cryptocurrency transactions and shared its value with several outside collectors through the blockchain system, which have taken part of the value of the famous and precious painting after completing the transaction.
At the beginning of the establishment of the block chain system, a block chain block is arranged in the obtained block chain system according to the information provided by the famous picture seller, the famous picture is recorded to be sold to a user M5 by a user M4 in 1963, and the transaction amount is 5 ten thousand yuan. The blockchain system carries out simulation modification on the blockchain block, modifies the related transaction amount to 10 ten thousand yuan, and as a result, the property right share of the goods value of all the blockchain nodes is not influenced, so that the block attribute of the blockchain block is marked as a modifiable block, and the hash value in the blockchain block is set to be a fixed value.
After a while, user M6 at a blockchain node gets very exact evidence, which is sufficient to prove that the buyer of the transaction is not user M5, but is another hidden buyer: user M7.
Then, the user M6 initiates a request for modifying the transaction information in the target blockchain block through the used blockchain nodes in the blockchain system, since the share of the draw value interest owned by the user M6 is only 0.6%, and cannot directly communicate with the blockchain nodes having the share of the draw value interest, the user M6 first communicates with the blockchain nodes at the same group level (i.e., the blockchain nodes having the share of the draw value interest less than 1%) one by one, and after obtaining sufficient consent of the blockchain nodes, forms a group of blockchain nodes containing 15 blockchain nodes, and the sum of the draw value interest shares corresponding to the group of blockchain nodes is greater than 10%. Then, communication with the blockchain node of a certain middle-level group is realized in a many-to-one mode, and communication with the blockchain node of the highest-level group is finally realized by adopting the same method.
After the communication is established, the formal information of a plurality of block link points indicating the approving of modification is obtained within a preset time. The system calculates the corresponding equity shares of the block chain link points, and the calculated proportion of the equity shares in the total amount exceeds 70 percent and is greater than 50 percent of a preset threshold value; then, carrying out simulation modification on the target block chain block, and determining whether value right share corresponding to all block chain link points changes; and finally, if the target block chain block is not changed, modifying the target block chain block, and if the value right share corresponding to at least one block chain link point is changed, not performing any subsequent operation.
It should be noted that the simulation modification described in the above embodiment is a modification that the system simulates the blockchain block, and does not substantially modify any content of the blockchain block, that is, the original information is still displayed on any terminal corresponding to the blockchain block.
According to the embodiment of the invention, the communication grade of the block chain node is set, so that the modification work of the target block chain block can be more effectively finished.
