Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with one or more embodiments of the present specification. Rather, they are merely examples of apparatus and methods consistent with certain aspects of one or more embodiments of the specification, as detailed in the claims which follow.

It should be noted that: in other embodiments, the steps of the corresponding methods are not necessarily performed in the order shown and described herein. In some other embodiments, the method may include more or fewer steps than those described herein. Moreover, a single step described in this specification may be broken down into multiple steps for description in other embodiments; multiple steps described in this specification may be combined into a single step in other embodiments.

Blockchains are generally divided into three types: public chain (Public Blockchain), private chain (PrivateBlockchain) and alliance chain (Consortium Blockchain). In addition, there are various types of combinations, such as private chain + federation chain, federation chain + public chain, and other different combinations. The most decentralized of these is the public chain. The public chain is represented by bitcoin and ether house, and the participants joining the public chain can read the data record on the chain, participate in transaction, compete for the accounting right of the new block, and the like, and each participant (i.e. node) can freely join and leave the network. The private chain is opposite, the data writing authority of the network is controlled by a certain organization or organization, and the data reading authority is regulated by the organization; briefly, the private chain can be a weakly centralized system with strict restrictions and few participating nodes, so that the private chain is more suitable for use within a particular organization. A federation chain is a block chain between a public chain and a private chain, and "partial decentralization" can be achieved. Each node in the federation chain usually has a corresponding entity organization or organization, and participants jointly maintain the operation of the block chain by authorizing to join the network and forming a profit-related federation. When receiving the blockchain transaction, the blockchain node may process the blockchain transaction in a manner in the related art, and does not need to implement special processing different from the related art, so that the blockchain node may be applied to the technical solution of the present specification regardless of the public chain, the private chain, or the alliance chain.

In the blockchain network, corresponding blockchain transactions are submitted to blockchain link points, corresponding intelligent contracts can be triggered and executed by the blockchain transactions, and complex functions can be realized by calling the intelligent contracts.

Of course, different intelligent contracts can be triggered and executed in the blockchain network through blockchain transaction to realize different functions, and each intelligent contract is used for realizing the corresponding function. Alternatively, different functions may be implemented by calling different interfaces in the same intelligent contract, one or more interfaces may be defined in the intelligent contract, each interface being used for implementing a corresponding function, and then when the intelligent contract is called through a blockchain transaction, which interface or interfaces defined in the intelligent contract are declared to be called to implement the corresponding function. Smart contracts are pre-deployed executable code on a blockchain that allows trusted transactions to be conducted without third parties, and which are traceable and irreversible. The management of the blockchain resources can be realized by invoking an intelligent contract, for example, converting the data under the chain into the corresponding blockchain resources, transferring the blockchain resources, or querying the quantity, etc.

With the popularization of healthy life, more and more people walk into a gymnasium or use outdoor fitness equipment in public places such as communities, schools and the like to exercise. At present, users corresponding to fitness equipment of a fitness room or outdoor fitness equipment are frequently changed, so that different exercise data generated by different users using the fitness equipment are often difficult to accurately associate with the users.

The intelligent contract can be called through the blockchain transaction to realize the management of blockchain resources obtained by converting the motion data. The following examples are given for illustrative purposes.

Fig. 1 is a schematic diagram of a network architecture provided by an exemplary embodiment. As shown in fig. 1, the client 10 may generate a blockchain transaction and may submit the transaction to the blockchain node 11n, so that the node 11n may chain the blockchain transaction submitted by the client 10 after recognizing with other nodes, and thus, may verify the blockchain transaction submitted by the client 10. Of course, node 11n, as well as other nodes, may invoke smart contracts to implement corresponding functionality based on blockchain transactions. The smart device 10 may include a smart device or a smart collection module included in the sports device, and the smart device 10 may further include an electronic device, such as a mobile phone, a tablet device, a notebook computer, a handheld computer (PDAs), a wearable device (e.g., smart glasses, a smart watch, etc.), and one or more embodiments of the present disclosure are not limited thereto.

The device registration set may record information corresponding to the sports device that submitted the registration transaction to the block link point and registered successfully.

In an embodiment, the motion device information may include a second signature generated by the motion device that generates the motion data for the motion data, that is, the motion data is signed by using a private key in an asymmetric key pair maintained by the motion device, then the block chain node may execute an intelligent contract code for signature verification, the block chain node may find, from public key information of a plurality of pre-stored motion devices, a second public key corresponding to the motion device that generates the motion data, or the resource creation transaction may include a certificate trust chain of the motion device, and the block chain node may obtain, from the certificate trust chain, the second public key corresponding to the motion device. The blockchain node may verify the second signature according to the second public key, and in the event that the second signature is verified according to the second public key, may determine that the mobile device is already registered in the blockchain. The asymmetric key pair may be generated by the motion device under the link or by other ways, and the key source is not limited in this specification.

In an embodiment, when each piece of user identity information has a corresponding blockchain account, the blockchain link point may update the blockchain account corresponding to the user identity information of the target user according to the number of the target blockchain resources, thereby implementing management of the blockchain resources. For example, the Balance (Balance) in the blockchain account corresponding to the user identity information of the target user is updated, and the like, which is not limited in this specification.

In an embodiment, in a case that a mapping relationship between the number of blockchain resources per conversion and corresponding user identity information is maintained in a blockchain account corresponding to an intelligent contract for managing blockchain resources, a blockchain link point may generate a mapping relationship between the number of target blockchain resources and user identity information corresponding to a target user, and may record the mapping relationship to a blockchain account corresponding to an intelligent contract for managing blockchain resources, thereby implementing management of blockchain resources.

Of course, when there is a corresponding blockchain account in each user identity information, a mapping relationship between the number of blockchain resources converted each time and the corresponding user identity information may also be maintained in the blockchain account corresponding to the intelligent contract for managing blockchain resources, which is not limited in this specification. The blockchain link point may update the blockchain account corresponding to the user identity information of the target user according to the number of the target blockchain, and at the same time, the blockchain link point may generate a mapping relationship between the number of the target blockchain resource and the user identity information corresponding to the target user, and may record the mapping relationship to the blockchain account corresponding to the intelligent contract for managing the blockchain resource, thereby implementing management of the blockchain resource.

In an embodiment, the user identity information may include a first signature generated by the target user for the motion data, that is, the motion data is signed by using a private key in an asymmetric key pair maintained by the target user, then the block chain node may execute an intelligent contract code for signature verification, the block chain node may find the first public key corresponding to the target user from pre-stored public key information of multiple users, or the resource creation transaction may include a certificate trust chain of the target user, and the block chain node may obtain the first public key corresponding to the target user from the certificate trust chain, where the source of the public key is not limited in this specification. The blockchain node may verify the first signature according to the first public key, and only execute the intelligent contract code for managing blockchain resources when the first signature is verified according to the first public key, so as to convert the motion data into target blockchain resources belonging to the target user, and may manage the blockchain resources corresponding to the user identity information according to the number of the target blockchain resources. That is to say, the precondition for converting the motion data into the target blockchain resource belonging to the target user and managing the blockchain resource corresponding to the user identity information according to the number of the target blockchain resources may include: and the first signature is verified to pass. The asymmetric key pair may be generated by a user device corresponding to a target user in a chain or by other ways, and the source of the key is not limited in this specification.

That is to say, the precondition for converting the motion data into the target blockchain resource belonging to the target user and managing the blockchain resource corresponding to the user identity information according to the number of the target blockchain resources may include: and respectively verifying the first signature and the second signature. In this specification, the order of generation of the first signature and the second signature is not limited, and the first signature may be generated first and then the second signature may be generated, or the second signature may be generated first and then the first signature may be generated.

In an embodiment, the block link point may further execute an intelligent contract code for verifying the motion data, so that the motion data may be matched with historical motion data, where all the motion data received by the block link node within a preset time period are recorded in the historical motion data, and the preset time period may be set according to an actual requirement, which is not limited in this specification. And the blockchain node executes the intelligent contract code for managing blockchain resources only if historical motion data matching the motion data is not found. That is to say, the precondition for converting the motion data into the target blockchain resource belonging to the target user and managing the blockchain resource corresponding to the user identity information according to the number of the target blockchain resources may include: no historical motion data matching the motion data is found. In the case where the historical motion data matching the motion data is found, the intelligent contract code for managing the blockchain resources may be rejected from being executed, so that the same motion data may be prevented from being used multiple times.

In an embodiment, the block link point may further receive a query transaction sent by a client, where the client may be a motion device generating the motion data, a user device corresponding to a target user, or another electronic device, and the description herein is not limited thereto. Under the condition that each piece of user identity information has a corresponding blockchain account, the blockchain link point can execute an intelligent contract code for inquiring blockchain resources according to the inquiry transaction, and then the blockchain link point can directly read the total number of blockchain resources corresponding to the target user from the blockchain account corresponding to the user identity information of the target user.

In one embodiment, the blockchain link point may receive a resource transfer transaction initiated by a first user, and in the case that there exists a corresponding blockchain account for each user identity information, the blockchain link point may transfer a specified amount of blockchain resources from the blockchain account corresponding to the first user to the blockchain account corresponding to a second user by executing an intelligent contract code for transferring blockchain resources.

In an embodiment, a blockchain link point may receive a resource transfer transaction initiated by a first user, and in a case that a mapping relationship between the number of blockchain resources per conversion and corresponding user identity information is maintained in a blockchain account corresponding to an intelligent contract for managing blockchain resources, the blockchain link point may change, by calling an intelligent contract code for transferring blockchain resources, user identity information of the first user in the mapping relationship containing a specified number of blockchain resources maintained in the blockchain account corresponding to the intelligent contract for managing blockchain resources into user identity information of a second user. For example, the number of the blockchain resources transferred from the first user to the second user is 10, the blockchain link point may include a mapping relationship "blockchain resource 20," user identity information of the first user "is modified to" blockchain resource 10, "user identity information of the first user" and "blockchain resource 10," user identity information of the second user "of the mapping relationship, and the like, which is not limited in this specification.

In an embodiment, the resource transfer transaction may further include a specific signature of the first user for a specific number of blockchain resources, that is, the specific number of blockchain resources are signed by using a private key of an asymmetric key pair maintained by the first user. The block chain node may execute the intelligent contract code for signature verification, may obtain a specified public key corresponding to the first user, may verify the specified signature according to the specified public key, and only if the specified signature is verified, the block chain node executes the intelligent contract code for transferring the block chain resource. That is, the precondition for executing the intelligent contract code for transferring the blockchain resources includes: the specified signature is verified.

In an embodiment, in a situation that a mapping relationship between the number of blockchain resources converted each time and corresponding user identity information is maintained in a blockchain account corresponding to an intelligent contract for managing blockchain resources, and the mapping relationship may further include identification information of a corresponding piece of sports equipment and identification information of a sports venue to which the piece of sports equipment belongs, where the identification information may include a corresponding number or name, and the like, which is not limited in this specification.

Then, the block link point may receive a passenger flow query transaction, where the passenger flow query transaction may include identification information of a target moving location or identification information of each target moving device, the block link point may execute an intelligent contract code for querying a passenger flow situation, the block link point may screen all specific mapping relationships including the target moving location from the mapping relationships, the block link point may count the number of block link resources converted each time according to the specific mapping relationships, or the block link point may screen all specific mapping relationships including the target moving device from the mapping relationships, and then the block link point may count the number of block link resources converted each time according to the specific mapping relationships, and the like, which is not limited in this specification. For example, the treadmill a and the treadmill B belong to the gym 01, the treadmill C and the treadmill D belong to the gym 02, and when the block link point receives a passenger flow query transaction for the gym 01, the block link point may execute an intelligent contract code for querying a passenger flow situation, and then the block link point may screen a mapping relation including the treadmill a and the treadmill B from a mapping relation maintained in a block chain account corresponding to an intelligent contract for managing block chain resources, and may perform statistics on the mapping relation including the treadmill a and the treadmill B, for example, may perform statistics on the number of block chain resources converted by the treadmill a and the treadmill B each time, may perform statistics on the number of times the treadmill a and the treadmill B are used, and the like.

Of course, in the intelligent contract for inquiring passenger flow conditions, only the statistics of the corresponding fitness equipment can be limited to be returned, and the privacy information of the corresponding user is not returned, so that the leakage of the privacy information of the user is avoided. The statistical value can be used for adjusting the production and operation strategy of the sport place, can evaluate the passenger flow volume of the sport place and the like, and is beneficial to the continuous and stable development of the sport place. And the intelligent contract can also limit that the received passenger flow inquiry transaction contains the signature of the corresponding motion equipment and execute the intelligent contract for inquiring the passenger flow condition only under the condition that the signature of the motion equipment is verified, thereby avoiding the leakage of the service condition of the motion equipment and preventing a third party from stealing related data.

In an embodiment, the intelligent contract code for managing blockchain resources, the intelligent contract code for verifying sports data, the intelligent contract code for signature verification, the intelligent contract code for querying blockchain resources, and the intelligent contract code for transferring blockchain resources may correspond to a plurality of interfaces in the same intelligent contract, respectively, or the intelligent contract code for managing blockchain resources, the intelligent contract code for verifying sports data, the intelligent contract code for signature verification, the intelligent contract code for querying blockchain resources, and the intelligent contract code for transferring blockchain resources may correspond to a plurality of intelligent contracts, respectively, which is not limited in this specification.

Alternatively, only the first signature generated by the target user for the target data may be included in the target data.

The device number of the sports device is recorded in the block chain account, so that the public key information corresponding to the device number can be conveniently and quickly searched subsequently, and the processing efficiency can be improved. Of course, the registration transaction may only include the public key information in the asymmetric key pair maintained by the motion device, which is not limited in this specification.

Similarly, each user may submit a registration transaction to the blockchain node, where the registration transaction may include public key information in the asymmetric key pair maintained by each user and a user number corresponding to each user, and then the blockchain node may execute an intelligent contract code for registration according to the registration transaction, so that a mapping relationship between the public key information and the user number of each user may be recorded in a blockchain account corresponding to the intelligent contract for registration, such as the user binding snapshot library shown in fig. 5. The user number of the sports equipment is recorded in the blockchain account, so that the public key information corresponding to each user can be conveniently and quickly searched subsequently, and the processing efficiency can be improved. Of course, the registration transaction may only include the public key information in the asymmetric key pair maintained by the user, which is not limited in this specification.

In step 402, the motion device 01 generates motion data X.

Step 403, sending the target data to the user A.

In the present embodiment, assuming that the user a exercises with the exercise device 01 for 20 minutes and the exercise distance is 3 kilometers, the exercise device 01 may generate exercise data X, which may include: the exercise time is as follows: 19:00-19:20, the movement time length T =20min, the movement distance L =3km and the equipment number 01. And the motion device 01 may generate a first signature for the motion data X, that is, the motion data X is signed by using a device private key of an asymmetric key pair maintained by the motion device 01, so as to generate target data including the motion data X and the first signature. The near field communication can be performed between the motion device 01 and the user device M corresponding to the user a, and then the motion device 01 can send the acquired target data to the user device M.

Step 404, processing the target data.

At step 405, a resource creation transaction is generated.

In this embodiment, the user a may perform a second signature on the motion data X in the obtained target data, that is, perform a signature on the motion data X by using a user private key of an asymmetric key pair maintained by the user a. The user A can generate a resource creation transaction and submit the resource creation transaction to the block node through the user equipment M, the resource creation transaction can include the motion data X, the first signature and the second signature, and the resource creation transaction can also include the equipment number 01 of the motion equipment 01 and the user number A of the user A.

In this embodiment, the sports device and the user respectively sign the sports data, so that the sports data can be effectively prevented from being tampered in the transmission process, meanwhile, the information of the sports device or the information of the user can be prevented from being tampered in the transmission process, and the reliability and the accuracy of the sports data received by the link nodes of the block can be improved.

At step 406, the smart contract for signature verification is executed.

In this embodiment, after receiving the resource creation transaction, the block link point may execute an intelligent contract code for signature verification, and the block link point may quickly find, according to the device number 01 and the user number a included in the resource creation transaction, a device public key 001 corresponding to the motion device 01 and a user public key 001 corresponding to the user a from the block chain account corresponding to the intelligent contract for registration, so that the first signature may be verified according to the device public key 001, and the second signature may be verified according to the user public key 001.

If the first signature is verified and the second signature is verified, the process proceeds to step 407. Wherein, the first signature verification pass can indicate that the sports data X is generated by the sports equipment 01 and is not tampered in the transmission process, and the second signature verification pass can indicate that the sports data X is generated by the user A for exercise and is not tampered in the transmission process.

And if the first signature or the second signature fails to verify, the resource creation transaction is rejected to be processed if the resource creation transaction is abnormal. The abnormal condition may include that the motion data X is tampered.

In step 407, an intelligent contract for verifying the motion data is executed.

In this embodiment, the link points of the block may execute an intelligent contract code for verifying the motion data, and the motion data X may be matched with the historical motion data, assuming that all the motion data received by the link nodes of the block within 10 minutes are recorded in the historical motion data.

If the blockchain node does not find the motion data X in the historical motion data, step 408 is performed.

If the block link point finds the historical motion data matched with the motion data X, the motion data X is uploaded, so that the resource creation transaction is rejected for processing, and the same motion data can be prevented from being processed for multiple times.

At step 408, an intelligent contract for managing blockchain resources is executed.

In this embodiment, the block chain node may execute intelligent contract code for managing block chain resources, so that the motion data X may be converted into motion credits attributed to the user a. The conversion rule between the motion data and the motion score is set in the intelligent contract for managing the blockchain resources, and of course, the conversion rule may be updated by means of upgrading the intelligent contract for managing the blockchain resources, and the conversion rule may be set according to actual needs, which is not limited in this specification.

In the present embodiment, it is assumed that the conversion rule between motion data and motion is: motion integral = length of motion times distance of motion, where length of motion is in minutes and distance of motion is in kilometers. Then it can be determined that user a achieved the exercise score =20 x 3=60 points for the current workout.

In this embodiment, when each piece of user identity information has a corresponding blockchain account, the blockchain link point may add the motion score 60 generated by this conversion to the blockchain account corresponding to the user a. Assume that the user a's corresponding blockchain account has a total movement integral of 80 points after updating.

Alternatively, in the case that the mapping relationship between the number of blockchain resources per conversion and the corresponding user identity information is maintained in the blockchain account corresponding to the intelligent contract for managing blockchain resources, the blockchain link point may generate the mapping relationship between the motion score 60 and the user a, and record the mapping relationship into the blockchain account corresponding to the intelligent contract for managing blockchain resources, as shown in fig. 6. Of course, the mapping relationship may also record specific motion data and identification information such as a device number corresponding to the device, which is not limited in this specification.

At step 409, a query transaction is received.

In step 410, a smart contract for querying motion integrals is executed.

In this embodiment, in the case that there is a corresponding blockchain account for each user identity information, the blockchain link point may receive a query transaction for querying the motion score of the user a. The block chain node may execute an intelligent contract code for querying the motion score according to the query transaction, and the block chain node may directly read the total number of the motion score corresponding to the user a, that is, 80 points, from the block chain account corresponding to the user a.

In this embodiment, in the case that a mapping relationship between the number of the motion scores of each conversion and the corresponding user identity information is maintained in the blockchain account corresponding to the intelligent contract for managing blockchain resources, the blockchain link point may receive an inquiry transaction for inquiring the motion scores of the user a. Then the block chain node may execute the intelligent contract code for querying the motion score according to the query transaction, and the block chain node may filter out a specific mapping relationship containing the user a from the block chain account corresponding to the intelligent contract for managing the block chain resources, as shown in fig. 6, where the specific mapping relationship includes "user a, motion score: 20 points "and" user a, motion score 60 points ", then the motion score for each conversion included in the specific mapping relationship can be counted, so that the total number of motion scores corresponding to the user a, that is, 80 points, can be obtained.

In step 411, a motion point transfer transaction is received.

At step 412, a smart contract for transferring motion integrals is executed.

In this embodiment, in the case that each user identity information has a corresponding blockchain account, a blockchain link point may receive a point transfer transaction initiated by a user a, where the point transfer transaction may include transferring a sports point 20 point from the user a to a user B, and the point transfer transaction may further include a specified signature of the user a for the sports point 20 point. The block chain node may execute the smart contract code for signature verification so that the specified signature may be verified against user a's user public key 001. In the case that the designated signature is verified, the block chain link point may execute the smart contract code for transferring the motion score, so that the motion score 20 in the block chain account corresponding to the user a may be transferred to the block chain account corresponding to the user B. However, in the case that the verification of the specified signature fails, it indicates that the credit transfer transaction is abnormal, so that the credit transfer transaction may be rejected and warning information may be provided to corresponding personnel, which is not limited in this specification.

In this embodiment, in a situation that a mapping relationship between the number of the movement points per conversion and the corresponding user identity information is maintained in a blockchain account corresponding to an intelligent contract for managing blockchain resources, a blockchain node may receive a point transfer transaction initiated by a user a, where the point transfer transaction may include transferring the movement points 20 points from the user a to a user B, and the point transfer transaction may further include a specified signature of the user a for the movement points 20 points. The block chain node may execute the smart contract code for signature verification so that the specified signature may be verified against user a's user public key 001. In the case that the designated signature is verified, the blockchain link point may execute the smart contract code for transferring the motion score, and may use a mapping relationship "user a, motion score: 20 points "change to" user B, motion score: 20min ", thereby realizing the transfer of motion integration.

In this embodiment, the user a signs the motion score to be transferred included in the score transfer transaction, so that the blockchain node can verify the identity information of the user a conveniently, the security of the process of transferring the motion score can be ensured, and the motion score can be effectively prevented from being transferred by others due to counterfeiting the identity information of the user.

In the present embodiment, it is assumed that an intelligent contract for registration, an intelligent contract for signature verification, an intelligent contract for checking motion data, an intelligent contract for managing a block chain resource, an intelligent contract for inquiring motion points, and an intelligent contract for transferring motion points correspond to a plurality of intelligent contracts, respectively, and of course, an intelligent contract for registration, an intelligent contract for signature verification, an intelligent contract for checking motion data, an intelligent contract for managing a block chain resource, an intelligent contract for inquiring motion points, and an intelligent contract for transferring motion points may correspond to a plurality of different interfaces in the same intelligent contract, respectively, which is not limited in this specification.
