For the purpose of better explaining the present invention and to facilitate understanding, the present invention will be described in detail by way of specific embodiments with reference to the accompanying drawings.
The block chain system and the data processing method, device and storage medium thereof provided by the embodiment of the invention determine that the processing device has new requirements to occupy computing resources when the processing device receives the physiological characteristic information by acquiring the physiological characteristic information when a user browses a shopping website and sending the physiological characteristic information to the node sharing processing device in the block chain system, judge whether the task quantity currently operated by the processing device exceeds a preset quantity, if the task quantity currently operated by the processing device exceeds the preset quantity, acquire the task with the largest block chain node in the tasks currently operated by the processing device, suspend the task with the largest block chain node from the processing device to release the occupied computing resources so that the processing device can analyze the physiological characteristic information, and acquire the emotional characteristic information associated with commodities on the shopping website according to the analysis result, and generates commodity recommendation information according to the emotional characteristic information.

In order to better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can 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 invention to those skilled in the art.
Fig. 1 is a flowchart of a data processing method based on a blockchain system according to an embodiment of the present invention, and referring to fig. 1, the data processing method based on the blockchain system includes the following steps:
step S101, acquiring physiological characteristic information when a user browses a shopping website, and sending the physiological characteristic information to a block chain system, wherein the block chain system comprises a plurality of sub-block chain groups, and nodes in the plurality of sub-block chain groups share processing equipment.
Specifically, when a user carries out online shopping, the user can browse commodities through a shopping website, and in the process, the shopping website can acquire physiological characteristic information of the user when the user browses the shopping website through corresponding acquisition equipment and send the physiological characteristic information to the block chain system.
For example, the physiological characteristic information may be brain wave information, and may be acquired by a brain wave acquisition device. The brain wave acquisition equipment can be wearable equipment with a brain wave acquisition sensor, when a user browses commodities, the wearable equipment is worn on the brain of the user, the acquisition end of the brain wave acquisition sensor is close to the brain, in the commodity browsing process of the user, commodity information can be converted into brain signals in a thinking environment through some media, the user understands and memorizes commodity information through cognitive processing and generates psychological activity, meanwhile, the brain wave of the user can generate series changes based on the psychological activity of the user and the reaction of emotion, in the process, the brain wave acquisition equipment acquires the brain wave information of the user and sends the brain wave information to a block chain system.
For another example, the physiological characteristic information may be pulse information, which may be acquired by a pulse acquisition device. The pulse acquisition equipment can be wearable equipment with a pulse acquisition sensor, when a user browses commodities, the wearable equipment is worn on the wrist of the user, the acquisition end of the pulse acquisition sensor is made to be attached to the pulse of the wrist of the user, in the commodity browsing process of the user, the pulse of the user can generate series changes based on the psychological activity and emotion reaction of the user, the pulse acquisition equipment acquires the pulse information of the user, and the pulse information is sent to the block chain system.
Of course, the physiological characteristic information may be voice characteristic information or the like as long as the emotional characteristic information of the user can be directly reflected.
The blockchain system is a distributed system sharing accounts and databases, and may include a plurality of subblock chain groups, and nodes in the plurality of subblock chain groups share a processing device. For example, referring to fig. 2, the blockchain system may include three subblock chain groups, each subblock chain group has a plurality of nodes, and some nodes in the three subblock chain groups share a processing device, which is mainly used for processing data that does not need to be processed in time, and may be a server or any other device with certain computing power disposed in the blockchain system. For example, because the timeliness requirement of the user on the commodity recommendation is not high, the physiological characteristic information of the user can be sent to the processing device and processed by the processing device, so that the computing resource of the block chain system is saved.
Step S102, when the processing device receives the physiological characteristic information, determining that the processing device has a new requirement to occupy the computing resource, and judging whether the task amount currently operated by the processing device exceeds a preset amount.
Specifically, when the processing device receives the physiological characteristic information of the user, it can be determined that the processing device has a new requirement and needs to occupy the computing resource, and at this time, the task amount currently running by the processing device is obtained, and whether the task amount exceeds the preset amount is judged.
It should be noted that, the initial value of the task amount currently run by the processing device is 0, when the processing device runs the verification and broadcast task of one node, the task amount is increased by 1, and meanwhile, the processing device is added as one node to the sub-block chain group corresponding to the node, and so on, the task amount currently run by the processing device can be obtained. The preset value is the total number of tasks that the computing resources of the processing device can allow to run at most, and can be specifically determined according to the performance of the processing device.
Step S103, if the task amount currently operated by the processing equipment exceeds the preset amount, acquiring the task with the most block chain node in the tasks currently operated by the processing equipment, and suspending the task with the most block chain node from the processing equipment to release occupied computing resources so that the processing equipment can analyze the physiological characteristic information.
That is, when the amount of tasks currently run by the processing device exceeds the total number of tasks allowed by the processing device, the allocation of computing resources is performed, for example, the task having the most blockchain node among the tasks currently run by the processing device is acquired, and the task having the most blockchain node is suspended from the processing device to release the occupied computing resources, so that the processing device can analyze the physiological characteristic information.
Specifically, the processing device may run multiple tasks at the same time, and the processing device may perform information interaction with the sub-block chain group corresponding to the currently running task to obtain the number of nodes in the sub-block chain group corresponding to the currently running task, determine, according to the number of nodes, a task having the largest block chain node among the currently running task, and then suspend the task from the processing device to release the computing resource occupied by the task, so that the processing device analyzes the physiological characteristic information.
It should be noted that when the processing device receives a plurality of physiological characteristic information, the plurality of physiological characteristic information may be analyzed simultaneously in the case of sufficient computing resources of the processing device, and the plurality of physiological characteristic information may be analyzed one by one in the receiving order in the case of insufficient computing resources of the processing device. That is to say, when the processing device receives a plurality of physiological characteristic information, because the real-time requirement for physiological characteristic information analysis is not high, under the condition that the computing resources of the processing device are limited, the physiological characteristic information is analyzed one by one according to the receiving sequence so as to reduce the occupation of the computing resources of the block chain system, and under the condition that the computing resources of the processing device are sufficient, the physiological characteristic information can be analyzed simultaneously so as to ensure the timeliness of commodity recommendation as much as possible.
And step S104, acquiring emotional characteristic information associated with the commodities on the shopping website according to the analysis result, and generating commodity recommendation information according to the emotional characteristic information.
Specifically, the processing device may obtain emotional characteristic information of the user by parsing physiological characteristic information of the user. For example, when the physiological characteristic information is brain wave information, a brain wave spectrum of the user may be obtained by analyzing the brain wave information, and emotional characteristic information of the user, which may be positive, neutral, and negative, may be obtained from the brain wave spectrum. For example, when the user sees a favorite commodity, the brain wave spectrum of the user is a, and it can be determined that the emotion of the user is positive; if the user sees a very annoying item, the user's brain wave spectrum is B, and it can be determined that the user's emotion is negative.
For another example, when the physiological characteristic information is pulse information, a pulse spectrum of the user can be obtained by analyzing the pulse information, and emotional characteristic information of the user, which may be positive, neutral, and negative, can be obtained from the pulse spectrum. For example, when the user sees a favorite commodity, the pulse spectrum of the user is C, and it can be determined that the emotion of the user is positive; if the user sees a very annoying item, the user's pulse spectrum is D, at which point it can be determined that the user's mood is negative.
After the processing device analyzes the physiological characteristic information of the user to obtain the emotional characteristic information of the user, the product corresponding to the emotional characteristic information can be obtained from the shopping website according to the emotional characteristic information, and corresponding product recommendation information is generated. For example, when the emotional information of the user is positive, a large number of commodities similar to the commodity currently viewed by the user may be recommended; when the emotion information of the user is negative, a commodity which is not similar to the commodity can be recommended; when the emotion information of the user is neutral, the user can recommend commodities similar to the commodities currently browsed by the user or recommend different commodities, and the proportion of the occupied commodities is high. Thus, commodity recommendation to the user is achieved.
In the above example, by recommending the commodity according to the emotional characteristic information of the user, since the emotional characteristic information can directly reflect the current real psychological state of the user, even if the user does not purchase the commodity being browsed, the commodity can be well recommended to the user based on the emotional characteristic information, thereby solving the technical problem that the user cannot obtain a good recommendation result when purchasing other commodities not purchased due to commodity recommendation based on historical purchase information; meanwhile, the requirement on the real-time performance of commodity recommendation is not high, so that the physiological characteristic information of the user is sent to the shared processing equipment in the block chain system for processing, and the shared processing equipment processes one or more pieces of physiological characteristic information, so that the computing resources of the block chain system can be saved.
In an embodiment of the present invention, referring to fig. 3, the data processing method based on the blockchain system further includes:
step S301, when the blockchain system receives a transaction request generated by a user according to the commodity recommendation information, the transaction request is randomly allocated to any one of the sub-blockchain groups, so that each sub-blockchain group receives different transaction requests, and the production nodes in different sub-blockchain groups are processed in parallel, wherein each sub-blockchain group has identification information.
Specifically, after the block chain system generates commodity recommendation information based on the emotional characteristic information of the user, the commodity recommendation information is sent to a shopping website, and the user can select commodities meeting the needs of the user according to the commodity recommendation information. When a user finishes selecting and conducting transaction, a shopping website sends a transaction request to a blockchain system, the blockchain system randomly distributes the transaction request to any one of the subblock chain groups after receiving the transaction request, and each transaction request is not repeatedly distributed, so that the transaction requests received by each subblock chain group are different, and thus, production nodes in different subblock chain groups can process the received transaction requests in parallel, namely, a plurality of transaction requests can be processed at the same time, so that the processing speed can be increased, the transaction can be quickly finished, and the waiting time of the user can be reduced. For example, referring to fig. 2, when the blockchain system receives a transaction request from a user, the transaction request may be randomly allocated to any one of the subblock chain groups, such as the subblock chain group, and assuming that there are currently 3 transaction requests and randomly allocated to the subblock chain group 1, the subblock chain group 2 and the subblock chain group 3, the production nodes in the three subblock chain groups will process the 3 transaction requests simultaneously to ensure the timeliness of each transaction and reduce the waiting time of the user.
That is, when the same time blockchain system receives a plurality of transaction requests, the plurality of transaction requests can be randomly distributed to a plurality of sub-blockchain groups, and the plurality of sub-blockchain groups simultaneously process the plurality of transaction requests, so as to ensure the timeliness of transactions and reduce the waiting time of users.
Step S302, based on the POW consensus mechanism, a production node with the accounting right is generated through each sub-block chain group, and the packaged transaction processing result in the corresponding sub-block chain group and the identification information of the sub-block chain group are broadcast through the production node with the accounting right.
Specifically, the accounting right of the production node may be distributed through each sub-block chain group based on the POW common identification mechanism, that is, the ownership of the accounting right is determined, then when the transaction processing result reaches the production condition, the production node with the accounting right packages the transaction request in the sub-block chain group to which the production node belongs to form the transaction processing result, and performs the network-wide broadcast on the packaged transaction processing result and the identification information (unique encoding information) of the sub-block chain group, which is generated when the sub-block chain group is divided. The determination method that the transaction processing result reaches the production condition may be various, for example, the production time interval of the transaction processing result is preset, when the production node with the accounting right performs production, the production node with the accounting right judges whether the time difference between the current time and the production time of the previous transaction processing result reaches the preset production time interval of the transaction processing result in real time, and if so, the transaction processing result is determined to reach the production condition.
It should be noted that, when any one of the sub-blockchain groups receives a randomly allocated transaction request, the processing manner of the production node in the sub-blockchain group to the transaction request is various, for example, when the production node in any one of the sub-blockchain groups receives a randomly allocated transaction request, the production node in any one of the sub-blockchain groups judges whether the transaction request is a transaction request allocated to its own sub-blockchain group according to the allocation information of the blockchain system, if so, the transaction request is locally stored, otherwise, the transaction request is not stored but broadcasted, so that the nodes in the same sub-blockchain group may not have a direct connection in the blockchain system, and the transaction request belonging to the own sub-blockchain group can be obtained by broadcasting the transaction request by the nodes in other sub-blockchain groups, thereby reducing the connection load between the nodes.
As an example, when any one of the sub-blockchain groups receives a randomly assigned transaction request, the production nodes in that sub-blockchain group produce the transaction request result according to the assigned transaction request, while nodes of other sub-blockchain groups broadcast the transaction request to which that sub-blockchain group is assigned.
As another example, the blockchain system presets an assignment range, presets a subblock chain group corresponding to each assignment in the assignment range, when a new transaction request is generated, the blockchain system assigns a random value within the assignment range to the transaction request, when any production node in the blockchain receives the new transaction request, determines whether the new transaction request is assigned to the subblock chain group to which the new transaction request belongs according to the random value, if so, locally stores the new transaction request, and if not, broadcasts the new transaction request.
It should be noted that the node sharing the processing device in the sub-block chain group is different from the production node having the accounting right, wherein the node sharing the processing device is mainly used for processing data that does not need to be processed in time to save the computing resources of the block chain system, and the production node having the accounting right is mainly used for processing data that needs to be processed in time in parallel to increase the data processing speed, so the node sharing the processing device is different from the production node having the accounting right.
In step S303, each node in the blockchain system verifies and executes the received transaction processing result sequence according to the identification information of the sub-blockchain group to create a serial blockchain.
That is, when each node in the blockchain system receives the transaction request result, the verification and execution processes of the transaction request result are performed according to the sequence of the sub-blockchain groups (for example, according to the sequence of english letters in the identification information of the sub-blockchain groups, or the sequence of numbers) to construct a serial blockchain.
As an example, when the number of the sub-block chain groups in the block chain system is 3, numbering each sub-block chain group by 1, 2, and 3, when each node in the block chain system receives a broadcast packet (the broadcast packet includes a transaction request result and identification information of the sub-block chain group corresponding to the transaction request result), parsing the broadcast packet to obtain the transaction request result and the identification information of the sub-block chain group corresponding to the transaction request result, and verifying whether the identification information of the sub-block chain group corresponding to the current broadcast packet is 1, if yes, executing the transaction request included in the transaction request result in the broadcast packet, and linking the sub-block chain group to the block chain after the execution is completed; if not, caching the broadcast packet, verifying and executing the transaction request result according to the sequence of the identification information of the sub-block chain group after the broadcast packet with the identification information of the sub-block chain group being 1 is obtained, and linking the corresponding transaction request result to the block chain according to the sequence after the verification and the execution are finished so as to construct a serial block chain.
As another example, a variable may be set in the blockchain system, and the variable may be used to record the identification information of the sub-blockchain group corresponding to the result of the transaction request that has been currently validated and executed, so that each node in the blockchain system determines whether the transaction request result in the current broadcast packet is the transaction request result in the corresponding sequence when receiving the broadcast packet, and after the verification and execution in the numbering order in the sub-blockchain group are completed, the variable is set to an initial value, for example, when the number of the sub-blockchain groups is 3, when the sub-blockchain groups are numbered with 1, 2 and 3, after the transaction request result produced by the sub-blockchain group corresponding to the value 3 is verified and executed, the variable is set to 1, and thus, the transaction request results generated in the blockchain are circularly verified and executed to construct a serial blockchain.
In the above example, considering that the requirement on real-time performance of commodity transaction is high, when the blockchain system receives a plurality of transaction requests of a user, the transaction requests of the user are randomly allocated to any one of the sub-blockchain groups, so that each sub-blockchain group receives different transaction requests, and thus, production nodes in different sub-blockchain groups perform parallel processing on the transaction requests, the processing speed is greatly improved, the transaction is quickly completed, and the waiting time of the user is reduced.
