The invention provides a task demand response method based on a block chain.
Referring to fig. 2, fig. 2 is a flowchart of a first embodiment of a task demand response method based on a blockchain according to the present invention.
In this embodiment, the task demand response method based on the blockchain includes:
step S10, receiving tasks participating in demand response based on a preset block chain, and acquiring evaluation indexes of the tasks;
in this embodiment, the related art based on the blockchain constructs an architecture of the blockchain system, and builds a preset blockchain based on the architecture. Specifically, the preset blockchain is constructed in a decentralised form, and the preset blockchain can be controlled by a plurality of mechanism centers, namely, the preset blockchain is controlled by each entity node. The nodes coordinate to maintain the whole preset block chain together according to a consensus mechanism. The preset blockchain may be used to increase participants, i.e., to increase nodes of or connect applications, devices, organizations, etc. to nodes. After the preliminary construction of the preset block chain is completed, a task participating in demand response is received based on the preset block chain, and an evaluation index of the task is obtained to determine the type of the task based on the evaluation index.
The task of participating in the demand response is generated by a node such as an application, a device, a mechanism, or the like in the preset blockchain or an application, a device, a mechanism, or the like connected to the node. Of course, the task involved in the demand response may also be generated by an external application and then obtained by acquiring the preset blockchain.
In an embodiment, the evaluation index is task type information participating in demand response, for example, the tasks include storage, energy consumption, communication, bandwidth, time, flow and other indexes, each task can have the above indexes, and the task can select or establish corresponding indexes according to own service and demand so as to meet different service demands. Of course, the task may select one or more indexes according to its own service requirement, i.e. different service requirements are connected to different evaluation indexes. In other embodiments, the evaluation index may also include other indexes, or more or less evaluation indexes, which are not limited herein.
In an embodiment, by setting different index nodes in a preset blockchain and ensuring data security, reliability of task demand data is realized according to different task demands. Wherein the index nodes are used for processing functions of the corresponding index, such as storing data, transmitting data, etc. In addition, the interaction data among the nodes are verified through the digital signature technology, mutual trust is not needed, mutual deception among the nodes can not be realized only according to the set rule of the preset block chain, and therefore the data security can be ensured. Meanwhile, as the nodes are de-trusted, the nodes do not need to disclose identities, each participating node is anonymous, the current node cannot tamper with other nodes, and the data interaction between the nodes is traceable, so that the data security can be ensured.
For easy understanding of the architecture of the blockchain system, reference may be made to fig. 3, where fig. 3 is a schematic diagram of the architecture of the blockchain system according to an embodiment of the present invention, and in which intelligent driving, smart medicine, research institutions, load aggregation, smart home, service companies are applications or institutions generating tasks, which are connected to the blockchain, and synchronous between nodes is performed to obtain a synchronous block. The architecture of the whole blockchain is controlled by a plurality of institutions (such as intelligent driving, intelligent medical treatment, research institutions, load aggregation, intelligent home, service companies), the blockchain supports point-to-point transaction of massive application requirements, information among nodes is disclosed and transparent, and a decentralised distributed system is formed by means of distributed accounting, propagation and the like. Because of the difference of task demands of all institutions, different demands are made on privacy, safety, supervision and the like of data, and by constructing the architecture, the above various demands can be met, the overall data processing speed in the blockchain is improved, more interactive information can be processed in a short time, and therefore, the data safety can be ensured and the processing capacity of single nodes in the blockchain can be improved.
Step S20, selecting a target block from all blocks of the preset block chain based on the evaluation index;
when the preset block chain is divided into blocks, a plurality of different evaluation indexes such as storage, energy consumption, communication, bandwidth, time and flow can be set first, and then the duty ratio of the evaluation indexes in each task requirement is calculated respectively. Since the evaluation indexes have different properties and usually have different dimensions and magnitude, when the level differences among the evaluation indexes are large, if the original duty ratio is directly used for analysis, the classification processing is not accurate enough, so that in order to ensure the reliability of the result, the duty ratio needs to be standardized, and the standardized processing can be realized through a data standardization algorithm, for example, an extremum method, a standard deviation method, a tri-fold line method, a semi-normal distribution method and the like, which are not described herein. Then, based on the duty ratio of the normalization process, the similarity distance between the respective tasks is calculated for different indexes, for example, the euclidean distance, the L1 norm, and the like, which are not limited herein. Finally, each task can be classified based on the similarity distance, and the preset block chain is divided into blocks based on the classified blocks. After the above classification process, a corresponding target block may be selected for the task newly received by the preset blockchain. Specifically, a target block is selected from the blocks of the preset blockchain based on the task evaluation index.
It should be noted that, each task has a unique identifier, for example, an ID (Identity document, identity identifier), and after the task is selected from the target block, the unique identifier and the task can be passed to the target block together, so that the target block can accurately and rapidly process the task.
In addition, it should be noted that, each block of the preset blockchain is connected with each other, each node, task, index, etc. in the block are connected with each other, and based on the consensus mechanism, the nodes or blocks can share respective messages.
In an embodiment, a target block for the connection is determined according to the priority of the evaluation index, and the target block may be one or more. Specifically, referring to fig. 4, fig. 4 is a schematic block-chain block connection diagram according to an embodiment of the present invention, where the priority of the storage index and the bandwidth index in the relevant task of intelligent medical treatment is higher, so that two block-chain node services are respectively selected as target blocks. The processing procedures of other mechanisms or applications in the figure are basically the same as those of the intelligent medical treatment, and are not described in detail herein. In other embodiments, the target area for the connection may be determined according to factors such as the weight, importance, and duty ratio of the evaluation index.
Specifically, the step S20 includes:
step a21, carrying out standardization processing on the plurality of evaluation indexes to obtain a plurality of standardized evaluation indexes;
step a22, carrying out weighting operation on the plurality of standardized evaluation indexes to obtain weights of the plurality of evaluation indexes;
step a23, selecting a target block from the blocks of the preset block chain based on the weight.
After the evaluation indexes of the task are obtained, the plurality of evaluation indexes are subjected to standardization processing based on a data standardization algorithm, then the plurality of standardized evaluation indexes are subjected to weighting operation to obtain weights of the plurality of evaluation indexes, and finally the target block is selected from all blocks of the preset block chain based on the weights. Wherein the evaluation index includes a plurality of indexes.
Since the evaluation indexes have different properties and usually have different dimensions and magnitude, if the level difference between the evaluation indexes is large, the evaluation indexes are not comparable if the original evaluation indexes are directly analyzed, and therefore, in order to ensure the reliability of the result, the normalization process needs to be performed on each evaluation index to eliminate the property difference (dimension difference) of each evaluation index.
The data normalization algorithm can be an extremum method, a standard deviation method, a tri-fold line method, a semi-normal distribution method and the like. The weighting operation may be a mean square error operation method, and of course, may be other methods for calculating weights.
In an embodiment, a block corresponding to the index with the largest weight can be selected as the target block, so that the demand response speed corresponding to the index with the largest weight is higher, and the interaction efficiency is higher. In other embodiments, a block corresponding to an index having a weight greater than a preset weight threshold may be selected as the target block, where the target block may include one or more target blocks, and the preset weight threshold may be set according to actual needs, which is not limited herein.
And step S30, distributing the task to the target block for processing.
After the target block is selected, the task is distributed to the target block for processing. Specifically, the processing is performed by the blockchain node service in the target block, that is, the response processing is performed by the service node with the corresponding demand response. It should be noted that, the task is allocated to the target block, and a unique identifier of the task is attached to the target block, so that the target block can index the task based on the unique identifier, thereby improving the response speed of the task requirement.
In an embodiment, after a task is allocated to a target block, the task and nodes in the target block form a chained storage network structure, and each node in the task and the target block can share information, so that data security can be ensured and response speed of task requirements can be improved based on a preset rule of the preset blockchain.
The embodiment of the invention provides a task demand response method based on a block chain, which is used for receiving tasks participating in demand response based on a preset block chain and acquiring evaluation indexes of the tasks; selecting a target block from all blocks of a preset block chain based on an evaluation index; and distributing the task to the target block for processing. The embodiment of the invention is based on the decentralised preset blockchain, so that the interaction between the data is carried out according to the established rule, specifically, the interaction data between the nodes is verified through the digital signature technology without mutual trust, the nodes cannot be deceived mutually, the nodes are deceived mutually, so that the nodes do not need to disclose identities, each participated node is anonymous, in addition, the current node cannot tamper with other nodes, the data interaction between the nodes can be traced, the reliability of the data under the task response requirement is ensured, and meanwhile, the corresponding target block is selected according to the evaluation index of the task, so that the task requirement can realize faster response speed under the corresponding target block. Therefore, the embodiment of the invention improves the reliability of the data and the response speed of the task demands.
Further, based on the first embodiment described above, a second embodiment of the task demand response method based on a blockchain of the present invention is presented.
Referring to fig. 5, fig. 5 is a flowchart illustrating a second embodiment of a task demand response method based on a blockchain according to the present invention.
In this embodiment, before the step S10, the task demand response method based on the blockchain further includes:
step S40, dividing a preset blockchain into side chains corresponding to a plurality of preset evaluation indexes, wherein the number of the side chains is the same as that of the plurality of evaluation indexes, and the side chains comprise nodes for processing tasks;
and S50, constructing a main chain in the preset blockchain, and respectively connecting each side chain with the main chain, wherein the main chain comprises a main node with a sharing function.
In this embodiment, the architecture of the main side chain is further designed based on the preset blockchain, and the task can select or establish a corresponding index according to its own service and requirement, so as to realize different service requirements through the main side chain. Specifically, the preset blockchain is divided into side chains corresponding to a plurality of preset evaluation indexes, wherein the number of the side chains is the same as that of the plurality of evaluation indexes, the side chains comprise nodes for processing tasks, then, a main chain is constructed in the preset blockchain, and each side chain is connected with the main chain respectively, wherein the main chain comprises a main node with a sharing function.
It should be noted that, the main chain is used as a sharing platform of all participants, that is, a sharing data channel of all nodes such as applications, task demands, devices, institutions, etc., so as to realize transaction and sharing among each evaluation index, block and main chain. Specifically, referring to fig. 6, fig. 6 is a schematic diagram of a main chain according to an embodiment of the present invention, where a bandwidth side chain includes five nodes, a time side chain includes five nodes, and of course, the number of nodes of the side chain is set according to an actual situation, which is not limited herein, and a main chain is used to connect the bandwidth side chain with the time side chain, and the main chain includes two main nodes, which are used to realize sharing of data, and of course, the number of main chain nodes is set according to an actual situation, which is not limited herein.

Of course, the task may select one or more indexes according to its own service requirement, i.e. different service requirements are connected to different evaluation indexes. In other embodiments, the evaluation index may also include other indexes, or more or less evaluation indexes, which are not limited herein.
In the embodiment, the main side chain is designed for the task demands according to the evaluation indexes, so that the interaction efficiency between tasks with the same evaluation indexes is improved under the same side chain, and the processing and the linking of subsequent data are facilitated.
Further, based on the first embodiment described above, a third embodiment of the task demand response method based on a blockchain of the present invention is presented.
In this embodiment, the task demand response method based on the blockchain further includes:
step A, when detecting a request of an application to join the preset blockchain, verifying whether the application has a joining authority;
and step B, if the application has the joining authority, the application is added into the preset blockchain so as to enable information interaction between a plurality of applications based on the preset blockchain.
In this embodiment, the preset blockchain is controlled by multiple mechanism centers, and the application needs to obtain rights to join the preset blockchain. For the preset blockchain, when a request of adding the application into the preset blockchain is detected, whether the application has the adding authority is verified, and if the application has the adding authority, the application is added into the preset blockchain. After a plurality of applications join a preset blockchain, information interaction is performed between the plurality of applications based on the preset blockchain based on a preset rule of the blockchain.
In addition, it should be noted that, each block of the preset blockchain is connected with each other, each application, node, task, index, etc. in the block are connected with each other, each node may be connected with a different application, and based on a consensus mechanism, the applications may share respective messages. In addition, the nodes of the preset block chain are mutually synchronous, one node is lost in data, and other nodes are backed up with the data, so that the safety of the data can be ensured.
Specifically, in the step B, adding the application to the preset blockchain includes:

Wherein the unique identification may be an ID identification.
It should be noted that each application has a unique identifier, for example, an ID identifier, and when the application joins the preset blockchain, the unique identifier and the application may be handed to the preset blockchain together, so that the preset blockchain may accurately and quickly index and process the application.
In this embodiment, the added application is subjected to authority verification, so that the preset blockchain can be added only by the allowed application, thereby ensuring the reliability of the preset blockchain.
Further, based on the above-described first embodiment, a fourth embodiment of the task demand response method based on a blockchain of the present invention is proposed.

It can be understood that similarity calculation is performed on a plurality of tasks, that is, the types of the tasks are calculated, then the tasks are classified according to the types, and the classified tasks are respectively connected to each block. The preset similarity threshold is set according to actual needs, and is not limited herein, for example, when calculating the euclidean distance, the preset similarity threshold is an absolute distance.
When classifying tasks, it is necessary to calculate the difference between tasks. The similarity calculation is to compare the similarity of two tasks, namely calculating the characteristic value and the characteristic distance between the tasks, wherein if the characteristic distance is small, the similarity is large, and if the characteristic distance is large, the similarity is small.
