The Blockchain (Blockchain) is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism, an encryption algorithm and the like. The consensus mechanism is a mathematical algorithm for establishing trust and obtaining rights and interests among different nodes in the blockchain system.
A blockchain is essentially a decentralized database. The block chain is a series of data blocks which are associated by using a cryptographic method, and each data block contains information of one bitcoin network transaction, so that the validity (anti-counterfeiting) of the information is verified and the next block is generated.
In a narrow sense, the blockchain is a distributed account book which is a chain data structure formed by combining data blocks in a sequential connection mode according to a time sequence and is guaranteed in a cryptographic mode and cannot be tampered and forged.
Broadly, the blockchain technique is a completely new distributed infrastructure and computing approach that utilizes blockchain data structures to verify and store data, utilizes distributed node consensus algorithms to generate and update data, utilizes cryptography to secure data transmission and access, and utilizes intelligent contracts composed of automated script code to program and manipulate data.
Generally, a blockchain system consists of a data layer, a network layer, a consensus layer, a stimulus layer, a contract layer, and an application layer. The data layer encapsulates a bottom layer data block, basic data such as related data encryption and time stamp and a basic algorithm; the network layer comprises a distributed networking mechanism, a data transmission mechanism, a data verification mechanism and the like; the consensus layer mainly encapsulates various consensus algorithms of the network nodes; the incentive layer integrates economic factors into a block chain technology system, and mainly comprises an economic incentive issuing mechanism, an economic incentive distributing mechanism and the like; the contract layer mainly encapsulates various scripts, algorithms and intelligent contracts and is the basis of the programmable characteristic of the block chain; the application layer encapsulates various application scenarios and cases of the blockchain. In the model, a chained block structure based on a timestamp, a consensus mechanism of distributed nodes, economic excitation based on consensus computing power and a flexible programmable intelligent contract are the most representative innovation points of the block chain technology.
The virtual fitness application recommendation method based on the block chain provided by the embodiment of the invention can effectively realize automation and intellectualization of virtual fitness application recommendation in the block chain network. The method can utilize a transaction chain data structure of a block chain hash pointer and a mechanism of Hash calculation of cryptography and digital signature of cryptography to realize multi-level evidence confirmation in the transaction process, thereby realizing the trust problem among different individual transaction parties. Meanwhile, the block chain is used for storing the relevant information of the virtual fitness application, and the method has the characteristics of privacy protection, traceability, tamper resistance and the like.
Fig. 1 schematically shows a flowchart of a virtual fitness application recommendation method based on a blockchain according to an embodiment of the present invention, where an execution subject of the virtual fitness application recommendation method based on a blockchain may be a device with a computing processing function, such as a server and/or a mobile terminal.

In this embodiment of the present invention, the feedback information of the virtual fitness application may include the evaluation content and the given user score of the user (object) who has historically used any one of the virtual fitness applications stored in the blockchain. The evaluation content can include any form of text, voice, image, video and other evaluation data which can be converted into text and are submitted by the user to the virtual fitness application. The user score here may be a score range preset by the system, for example, a score of 5 is full, a score of 4-5 given by the user is satisfactory, a score of 3 is general, a score of 0-2 is unsatisfactory, and the like, and for example, five stars may be preset as full, and a score of 0-5 given by the user may be corresponding to the user score, which is not limited in the present invention.
In this embodiment of the present invention, the application information of the virtual fitness application may include a system category to which the virtual fitness application belongs, a system level corresponding to a system index of the system category to which the virtual fitness application belongs, a system score of the virtual fitness application, safety prompt information, and the like.
For example, all the virtual fitness applications of the tiles in the tile chain may be divided into a plurality of system categories, such as limit category, entertainment category, leisure category, medical category, sports category, and the like, and for each system category, one or more system indicators B ═ B may be further set1,B2,B3,., for example, the limit classes may further include three system indexes of severity, speed, and scene comfort, and one or more system levels may be further set for each system index, for example, the severity may be divided into three system levels of over-severity, moderate severity, and over-slowness, the speed may be divided into three system levels of over-high, moderate, and over-slow, and the scene comfort may be divided into three system levels of complexity, moderate, and simplicity. For each virtual fitness application in the blockchain, the system may preset a system class to which each virtual fitness application belongs and a system level corresponding to a system index of the system class to which the virtual fitness application belongs, and further may calculate a system score of the virtual fitness application according to the system level corresponding to the system index of the system class to which the virtual fitness application belongs, for example, assuming that the virtual fitness application a belongs to a limit class and has three system indexes B1，B2，B3And the system grades corresponding to the three system indexes are respectively b1，b2And b3Then the system score of the virtual fitness application a may be calculated according to the following formula:
S＝a1×b1+a2×b2+a3×b3(1)
wherein in the above formula (1), a1，a2And a3The constants are preset constants, and may be set according to a specific application scenario, which is not limited in the present invention.
It should be noted that the above descriptions of the system type, system index and system grade, system score, etc. of the virtual fitness application are only used for illustration, and the protection scope of the present invention is not limited to the above examples.

In other embodiments, the user information may further include any one or more of gender, age, identification (e.g., a mobile phone number, an identification number, etc., which may distinguish it from other users), preference information, etc. of the target object.
In the embodiment of the present invention, the method may further include a step of constructing a blockchain node and a blockchain network. For example, the blockchain network construction subsystem takes a company basic business organization as a minimum node, and one or more groups/companies participate in the construction of the shared sojourn-old-care mutual-help alliance intelligent virtual fitness application and experience information sharing and management transaction blockchain network.
In the embodiment of the invention, the shared information and the like can be stored and authenticated according to the predefined data structure mode, the information storage mode and the protocol, so as to ensure the high efficiency of information storage and information processing.
In the embodiment of the invention, two or more mutual-help alliance organizations for old people mutually provide services such as residence, nursing medical care, diet, health entertainment and the like in the aspect of client travel and old people care, enterprises or individuals registered in the system can share and manage related shared mutual-help alliance intelligent virtual fitness application and experience information, demand feedback information of old people clients to the virtual fitness application, experience feedback information of old people clients to the virtual fitness application (such as score, plot, feeling, frightening degree, reality, age sense and the like), complaint problem information of old people clients to the virtual fitness application service, operation flow and guidance guarantee information of the virtual fitness application service, safety prompt information of the virtual fitness application (such as heart old people or hypertensive old people are not suitable to participate in the fitness experience and the like) and other shared mutual-help alliance intelligent virtual application and experience information sharing and management update information are uploaded to a block chain, the method can prove that related materials such as audio, video and images of the related materials can also be uploaded to the block chain, and by utilizing the block chain technology, the characteristics of privacy protection (such as permission management, watermarking, encryption and the like), openness and transparency, traceability, difficulty in tampering and the like of data storage can be realized.
For example, the present invention provides a system for effectively implementing sharing of the intelligent virtual fitness application and experience information of the sojourn endowment mutual-aid alliance in the blockchain network, and an example of storing the sharing of the intelligent virtual fitness application and experience information and management information of the shared sojourn endowment mutual-aid alliance based on the data structure mode of the blockchain technology is shown in table 1 below:
TABLE 1
In step S120, when a recommendation request is received, target feedback information of a target object is extracted from the feedback information in the blockchain.
In the embodiment of the present invention, the recommendation request may be automatically triggered by the system, for example, when the system detects that the target object logs in the system application, a recommendation request may be automatically sent to the server through the client. Alternatively, the recommendation request may be triggered actively by the user, for example, if the target object clicks a "recommend" virtual button on the client, the client sends a recommendation request to the server.
In an embodiment of the present invention, the target feedback information may include user scores of the virtual fitness application and evaluation contents of system indexes of the virtual fitness application by the target object. The target object is for the currently received recommendation request, and the target object may be, for example, a certain elderly user, but the present invention is not limited thereto.
For example, the evaluation content may include an evaluation of the target object on each system index of a certain type of virtual fitness application, or, taking the virtual fitness application a as an example, the target object may evaluate the evaluation of each system index of the virtual fitness application a, such as the intensity, the speed, and the scene comfort level, whether the intensity is too strong, moderate, or too slow, whether the speed is too fast, moderate, or too slow, and whether the scene comfort level is complex, moderate, or simple.
In step S130, a recommended virtual fitness application responding to the recommendation request is determined according to the target feedback information and the application information and the user information in the blockchain.
According to the virtual fitness application recommendation method based on the block chain, on one hand, the relevant information of the virtual fitness application is stored by utilizing the block chain technology, a decentralized storage mode can be realized, the virtual fitness application recommendation method has the characteristics of privacy protection, traceability, tamper resistance and the like, and the safety and reliability of stored data are guaranteed, so that information leakage of user data in the relevant information of the virtual fitness application can be prevented, and the safety and accuracy of the user data are improved; on the other hand, feedback information and application information of the virtual fitness application stored in the block chain and the user information can be utilized to respond to the received recommendation request, and target feedback information of the target object can be extracted, so that the recommended virtual fitness application recommended to the target object can be determined according to the extracted target feedback information, the application information of the virtual fitness application in the block chain and the user information.
Fig. 2 schematically shows a flow chart of step S130 of fig. 1 in an embodiment.
As shown in fig. 2, the step S130 may further include the following steps in the embodiment of the present invention.
In step S131, a target virtual fitness application is determined according to the user score.
For example, all virtual fitness applications that have been scored historically by the target object may be extracted from the blockchain, and respective user scores of all virtual fitness applications by the target object may be obtained, and then the user scores may be ranked, and the virtual fitness application with the highest user score (assumed to be F) may be selected as the target virtual fitness application a'.
In step S132, a system score of the target virtual fitness application and a system level corresponding to the system index of the system category to which the target virtual fitness application belongs are obtained.
For example, the system score S ' of the target virtual fitness application a ' and the system level corresponding to the system index of the system category to which the target virtual fitness application a ' belongs may be extracted from the blockchain.
In step S133, the recommended virtual fitness application is determined according to the system score of the target virtual fitness application, the system level corresponding to the system index of the system category, the evaluation content, and the non-adaptive symptom information.
In the embodiment of the present invention, the evaluation content may include an evaluation of the target object on a system index of a system category to which the target virtual fitness application a 'belongs, for example, the target object evaluates the virtual fitness application a' with moderate severity, too fast speed, and moderate scene comfort.
In an exemplary embodiment, a difference value between the system scores of the recommended virtual fitness application and the target virtual fitness application is smaller than a preset threshold, a system level corresponding to a system index of a system category to which the recommended virtual fitness application belongs is matched with the evaluation content, and the safety prompt information of the recommended virtual fitness application does not include the non-adaptive symptom information.
For example, the system may find a virtual fitness application a "from the virtual fitness applications in the blockchain according to the system score S ' of the target virtual fitness application a ' and the system level corresponding to the system index of the system category, where the virtual fitness application a" and the target virtual fitness application a ' belong to the same system category, the system score S "of the virtual fitness application a" is closest to the system score S ' of the target virtual fitness application a ' (smaller than the preset threshold, and the value of the preset threshold may be set according to specific situations), and the speed index in the system index of the virtual fitness application a "is lower than that of the target virtual fitness application a ', the severity index and the scene comfort index of the virtual fitness application a" are similar to that of the target virtual fitness application a ', and the safety prompt information of the virtual fitness application a "does not include the non-corresponding symptom information of the target object, for example, if the non-adaptive symptom information of the target object is "hypertension", the safety prompt information of the virtual fitness application a "does not include" hypertension ", and in this case, the virtual fitness application a" may be used as the recommended virtual fitness application of the target object.
In the above embodiment, the recommended virtual fitness application is selected according to the information of the symptom that the user does not adapt to, but in other embodiments, the recommended virtual fitness application may be determined according to information of the user, such as age, height, sex, and preference, for example, if the target object is a child with a height less than 1.3 meters, the virtual fitness application that is suitable for the child is recommended for the target object.
