Description

Method, device and storage medium for controlling use of blockchain resources

Technical field

This application relates to the field of blockchain technology, and in particular, this application relates to a method, device, and storage medium for controlling the use of blockchain resources.

Background technique

Blockchain technology is a new application mode technology that combines computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, and encryption algorithms. Based on the blockchain platform, multiple blockchain applications can be developed. Blockchain applications can run on the IOS operating system and the Android operating system. For users of blockchain applications, the blockchain platform is approximately a "common land". If users of blockchain applications use blockchain platform resources normally, the underlying blockchain resources can fully meet user needs. However, if the blockchain platform encounters a malicious attack, it is easy to cause the abuse of blockchain resources and produce the so-called "tragedy of the commons."

In order to prevent the underlying blockchain resources from being abused, in the Ethereum project, each transaction initiated by the user needs to spend Gas (fuel cost), preventing the abuse of resources at the user's own cost. However, this also leads to a higher threshold for users, which directly increases the cost of use, which is not conducive to the large-scale application of projects in blockchain applications. The EOS (Enterprise Operation System) project proposes a mechanism similar to "margin", that is, a certain amount of frozen funds need to be deposited in each user account, and the blockchain resources that the account can use are directly proportional to its frozen funds. This method solves the problem that every transaction needs to consume, but it will lead to the problem of centralization. At the same time, it does not solve the threshold problem of using blockchain applications.

The method for controlling the use of blockchain resources based on the blockchain system provided in the embodiment of the present application can be applied to the hardware environment composed of the terminal 100 and the blockchain system 200 as shown in FIG. 1. As shown in FIG. 1, the terminal 100 and the blockchain system 200 are connected through a network. The method for controlling the use of blockchain resources based on the blockchain system provided in the embodiment of the present application may be in a server included in the blockchain system 200 carried out. The terminal 100 sends a transaction activity service application or a non-transaction activity service application to the blockchain system 200. The server included in the blockchain system 200 is used to respond to a transaction activity service application or a non-transaction activity service application sent by the terminal 100. , Processing the application for the transaction activity service or the application for the non-transaction activity service, and packaging the generated transaction information into a block and recording it in the blockchain. The terminal 100 may include terminal devices such as a notebook computer, a desktop computer, a tablet computer, and a mobile phone. The blockchain system 200 includes a plurality of blockchain nodes. A blockchain node can be a node that becomes a blockchain after successful server mining.

This application provides a method for controlling the use of blockchain resources based on the blockchain system, which is used to control the users of the terminal 100 to use the blockchain resources in the blockchain system 200. The following first explains the blockchain system 200 described in this application:

As shown in FIG. 2, the blockchain system 200 includes a blockchain technology platform 10 and a blockchain application 20. The blockchain technology platform 10 includes several blockchain nodes for providing blockchain resources and various basic functions to the blockchain application 20. The blockchain technology platform 10 provides a development environment and development resources for various applications developed based on the technology platform, and provides technical support for the use of the various applications.

The blockchain application 20 is an application developed based on the basic functions provided by the blockchain technology platform 10, and the blockchain application 20 uses the blockchain resources of the blockchain technology platform 10 at runtime. The blockchain resources provided by the blockchain technology platform 10 to the blockchain application 20 include non-transaction service resources required by the blockchain application 20 to implement non-transaction activities and transaction service resources required to implement transaction activities. This application is mainly aimed at controlling the use of blockchain resources when blockchain applications implement non-transactional activities. Specifically, the system issues a certain number of warrants to users of the blockchain application 20, which are used to pay users of the blockchain nodes in the blockchain technology platform 10 as non-transaction service resources provided by the blockchain technology platform 10. Virtual expenses.

When users of blockchain applications use the non-transaction type services provided by the blockchain technology platform, the system does not need to collect user tokens. However, it is precisely because the system provides users with non-transaction-type services for free, which has led to some malicious users abusing non-transaction services and wasting blockchain resources. For example, malicious users frequently use the non-transaction type services provided by the blockchain technology platform, which leads to the abuse of the blockchain resources of the underlying technology platform. The method for controlling the use of blockchain resources based on the blockchain system described in this application prevents malicious users from abusing the blockchain resources provided by the blockchain technology platform.

As shown in FIG. 3, in one embodiment, the method for controlling the use of blockchain resources based on the blockchain system described in this application includes the following steps:

S100. Issue a first preset number of warrants to users of the blockchain application; the warrants are virtual payments to the blockchain node when the user uses non-transaction service resources provided by the blockchain technology platform cost.

Warrants are consumption proofs that users consume non-transaction service resources provided by the blockchain technology platform and need to pay to the system. At the same time, the system also transfers the warrants consumed by users to the corresponding blockchain in the blockchain technology platform that provides non-transaction service resources node.

In this embodiment, the system issues a first preset number of warrants to users of the blockchain application, so that the user pays each of the services provided in the blockchain technology platform when using non-transaction service resources in the blockchain resources. Blockchain nodes. The first preset number of warrants may be determined according to the number of user-consumption warrants preset in a preset preset period of time.

In one embodiment, the blockchain application is an instant messaging application. The non-transaction service resources provided by users using the blockchain technology platform include users sending text messages, voice messages, and video messages through the instant messaging application. In order to ensure the normal use of ordinary users and prevent malicious attacks. The first preset number of warrants can be determined according to the following methods:

The amount of data used by the user to send messages using the instant messaging application within a preset period of time is obtained, and the number of warrants issued to the user by the system within the preset period of time is determined based on the amount of data.

In one embodiment, the method for controlling the use of a blockchain resource based on a blockchain system further includes: controlling an initial value of a warrant of a user of the blockchain application within a first preset time period to the first Preset number.

In this embodiment, the system periodically issues a first preset number of warrants to users of the blockchain application. The periodic issue of the first preset number of warrants for each of the first preset times. At the same time, an initial value of a user's warrant for controlling a blockchain application within each of the first preset times is the first preset number.

For example, the system first issues a first preset number of warrants to users of a blockchain application. After the first preset time period, it is detected that a certain number of warrants remain in the user's account. At this time, the system sets the number of warrants of the user to the first preset number within the next first preset time. For example, the system issues a first preset number of warrants to users of a blockchain application at 1:00 of the day. Regardless of whether the user has used the first preset number of warrants within the current day, the system resets the number of warrants of the user to the first preset number at 00:00 of the next day to ensure users of blockchain applications The initial value of the warrant in each day is the first preset number.

S200. When determining that a user of the blockchain application uses the non-transaction service resource provided by the blockchain technology platform, a corresponding number of warrants of the user are deducted according to the use situation.

In this embodiment, when the system detects that a user of a blockchain application uses a non-transaction service resource provided by a blockchain technology platform, the user will be deducted a corresponding number of warrants. The number of deducted warrants is directly proportional to the size of the non-transaction service resource used by the user. Deducting the corresponding number of warrants of the user according to the use situation may be: determining the number of users using the non-transaction service resource according to a preset calculation method, and then determining the deduction according to the relationship between the number of non-transaction service resources and the number of warrants The number of warrants.

For example, in one embodiment, the blockchain application is an instant messaging application, and the non-transaction service resource is an amount of data generated by a user sending a message through the instant messaging application. When the user sends a preset number of messages to generate a corresponding amount of data, the number of blockchain resources consumed by the blockchain technology platform, here is the number of the non-transaction service resources, so as to calculate the user sent through the instant messaging application The relationship between the amount of data generated by the message and the number of non-transaction service resources. Further, according to the relationship between the amount of data generated by the user sending the message through the instant messaging application and the number of consumed warrants, the warrants deducted when the user uses the non-transaction service resources provided by the blockchain technology platform are determined quantity.

In one embodiment, the blockchain application is an instant messaging application. Step S200 includes:

It is confirmed that when a user of the instant messaging application uses the blockchain technology platform for instant messaging, the user generates a corresponding amount of warrants based on the amount of data generated by the instant messaging.

In this embodiment, the instant messaging application is an application developed based on the blockchain technology platform. The instant messaging application performs functional operations through the blockchain resources provided by the blockchain technology platform. When a user of an instant messaging application uses the blockchain technology platform for instant communication, the non-transaction service resources provided by the blockchain technology platform are consumed, and the system deducts the corresponding number of warrants of the user according to the amount of data generated by the instant communication. Here, the amount of data generated by instant messaging includes the amount of data generated by sending text messages, voice messages, and video messages.

S300. When it is detected that the user of the blockchain application has zero warrants, authenticity verification of the user's identity is performed.

In this embodiment, when a user of a blockchain application uses the blockchain application, the non-transaction service resources provided by the blockchain technology platform are indirectly used. Each use consumes a corresponding number of warrants. Under normal circumstances, the system issues the number of warrants to users of the blockchain application within a preset period of time to meet the normal use of the users of each blockchain application within the preset period of time. However, if there is a malicious attack on the blockchain technology platform among the users of the blockchain application, if the blockchain resources are abused by using the blockchain application, the user's warrants will be quickly consumed within the preset time period. Finish.

At this time, when the system detects that the user of the blockchain application has zero warrants, the user's identity is verified for authenticity. Among them, the system can automatically detect whether the user's warrant for each blockchain application is zero. When it is detected that the user of the blockchain application has zero warrants, the user's identity is verified for authenticity. Alternatively, when the user's warrant of the blockchain application is zero, the user actively applies for identity authenticity verification to the system. After the system responds to the application of the user of the blockchain application, the identity of the user is verified.

S400. If the identity of the user passes the authenticity verification, issue a second preset number of warrants to the user.

When the users of the blockchain application have zero warrants, they may be maliciously attacking the users of the blockchain technology platform. For example, in the process of the server forming a blockchain node through "mining", the "mining" successful server becomes a blockchain node in the blockchain technology platform. However, when a "mining" unsuccessful server cannot become a blockchain node, it is likely to maliciously attack the blockchain technology platform, causing abuse and waste of blockchain resources in the platform. At the same time, it is not ruled out that some users of blockchain applications cause excessive use of warrants according to demand, resulting in warrants being zero for a preset time. Therefore, it is necessary to verify the authenticity of the user with zero warrants.

If the identity of the user of the blockchain application passes the authenticity verification, it means that the user is not a user who maliciously attacks the blockchain technology platform, and the user belongs to the blockchain resources provided by the blockchain technology platform within the normal scope. At this time, the system will issue a warrant to the user again so that the user can continue to use the non-transaction service resources of the blockchain technology platform.

In an embodiment, after the system verifies the identity of the user, the second preset number of warrants issued to the user is less than the first preset number of warrants. Specifically, each time a user's identity passes the authenticity verification, the number of warrants issued to the user by the system is less than the number of warrants issued last time. It can be that the number of warrants issued to the user by the system is half of the number of warrants issued last time.

In an embodiment, the method for controlling the use of blockchain resources based on the blockchain system further includes controlling the number of times that the warrant is issued to the same user within a second preset time period is less than a preset number of times. The second preset time may be the same as or different from the first preset time. For example, the system controls that the number of times a warrant is issued to the same user is less than a preset number of times in a day. After the preset number of times, even if the user's identity passes the authenticity verification again, the system will not issue a warrant to the user.

S500. If the identity of the user does not pass the authenticity verification, the user is prohibited from using the non-transaction service resource provided by the blockchain technology platform.

If the identity of the user of the blockchain application fails to verify the authenticity of the system, it means that the user is a user who maliciously attacks the blockchain technology platform, and the system will prohibit the user from subsequently using all the blockchain technology platform provided. Describe non-transaction service resources. The prohibition may be to temporarily freeze the user. For example, the user is prohibited from using the non-transaction service resource provided by the blockchain technology platform within a preset period of time. It may also be that the user is permanently prohibited from using the non-transaction service resources provided by the blockchain technology platform. The prohibited manner may be determined according to the user's use of the non-transaction service resource.

The method for controlling the use of blockchain resources provided in the above embodiments is used in a blockchain system to control the use of blockchain resources in the blockchain system. Blockchain systems include blockchain technology platforms and blockchain applications. This method issues warrants to users of blockchain applications for payment to blockchain nodes when using non-transaction service resources provided by the blockchain platform. When a user of a blockchain application uses the non-transaction service resources provided by the blockchain technology platform, the user's corresponding number of warrants is deducted according to the usage. The warrants of users of blockchain applications gradually decrease with usage. If the user maliciously attacks the blockchain platform and abuses the underlying blockchain resources of the platform, the user's warrants are consumed quickly. When the user has zero warrants, the system verifies the authenticity of the user's identity. If the user is a malicious attack platform and abuses the blockchain resources, the user's identity has not passed the authenticity verification of the system. At this time, the system will prohibit the user from using the non-transaction service resources provided by the blockchain technology platform. Abuse of blockchain resources by users in the chain technology platform. At the same time, if the user's identity has passed the system's authenticity verification, the system can continue to issue a corresponding number of warrants to the user to ensure that the authenticity of the platform users use the platform normally.

In an embodiment, after step S200, the method further includes:

S210. Transfer the corresponding number of warrants to a blockchain node in the blockchain technology platform.

In this embodiment, after the system deducts the corresponding number of warrants of the user of the blockchain application, the part of the warrants is transferred to a blockchain node in a blockchain technology platform that provides blockchain resources for the user.

In an embodiment, step S210 includes:

S211. Allocate the corresponding number of warrants to each blockchain node of the blockchain technology platform according to the workload of the blockchain node.

After step S211, the method further includes:

S213: Issue a corresponding number of tokens to each blockchain node according to the number of warrants of each blockchain node.

In this embodiment, the system transfers the warrants to the blockchain technology platform, and calculates each blockchain node's response based on the workload provided by each blockchain node to the users of the blockchain application in the blockchain technology platform. The number of obtained warrants, and according to the number of warrants that each blockchain node should obtain, the corresponding number of warrants are allocated to each blockchain node of the blockchain technology platform. Further, the system issues a corresponding number of tokens to each blockchain node according to the number of warrants of each blockchain node.

The following provides a specific implementation scenario to describe in detail the implementation process of a blockchain resource usage control method based on a blockchain system:

BCM: Blockchain Message, instant messaging application.

BCM warrants are chat warrants issued by the system for BCM users. BCM users need to own and spend BCM warrants to send messages using BCM. In addition, BCM warrants cannot be transferred between user accounts, nor can they be converted into tokens. They can only be transferred to the underlying blockchain nodes of the blockchain technology platform as proof of workload of the blockchain nodes.

The following will explain the three aspects of the issuance, cost and transaction fee of BCM warrants.

Issuance of BCM warrants:

The principle of issuing BCM warrants is based on ensuring the normal use of ordinary users and preventing malicious users from attacking the blockchain technology platform. First of all, according to the international standard for typing speed, a typical type 4 typist can enter 50 words per minute. Based on an average of 5 English half-width letters per word, a total of about 250 bytes. Assuming that the user is using BCM for text chat 24 hours a day, then a total of about 360,000 bytes are sent. According to the formula Bt = round (BQ / 1024), the user needs to spend about 352 BCM warrants. Among them, Bt represents the number of warrants, BQ represents bytes, and the round function represents rounding and deciding.

According to the statistical calculation of the communication data of users using voice chat and video chat, 1000 BCM warrants per day can meet the usage needs of normal users. The specific distribution rules are as follows:

1) When a BCM user registers an account, the system automatically issues 1,000 BCM warrants to the user.

2) Every day at 0 o'clock, the system automatically checks the balance of BCM warrants in the user account, and automatically resets the number of BCM warrants for each user account to 1,000.

3) The maximum limit of BCM warrants in user accounts is 1000; the maximum number of BCM warrants transferred from a single user account per day is also 1,000. If the system detects that the user has transferred more than 1,000 BCM warrants, the user is deemed to be cheating.

Cost of BCM warrants:

A BCM user sending a message using BCM is a transaction. Among them, sending a message requires a BCM ticket, and receiving a message does not require a BCM ticket. In order to reduce the processing pressure on the server and reduce the frequent calculation of the number of transactions, all messages sent by BCM users within 2 hours from the first message sent by the BCM user are packaged as one transaction. The number of BCM warrants required for this transaction is directly proportional to the amount of data sent by the message. Calculate the BCM warrants spent by users based on the following formula:

Bt = round (BQ / 1024)

Among them, Bt is the number of BCM warrants to be spent, BQ (Byte Quantity) is the total number of bytes of the message contained in the transaction, and the round function represents rounding and deciding.

For example, BCM user A sends a message to BCM user B at 10 o'clock, and then user A sends a total of 20 messages to BCM user C and BCM user D. As of 12 o'clock, BCM user A has sent a total of 51,224 bytes of messages to other users. When the system calculates the BCM warrants spent by BCM user A at 12 o'clock, BCM user A needs to deduct 50 BCM warrants.

If a BCM user runs out of 1,000 BCM warrants in a day, the system will use the CAPTCHA verification code to authenticate the user's authenticity. If the user passes the authenticity verification, the system will issue 1/2 * 1000 BCM warrants. A user can perform authenticity verification up to 4 times in a day, and the number of BCM warrants issued to the BCM user by the system after each verification is 1/2 of the number of warrants obtained last time. That is, each BCM user can obtain up to about 1938 BCM warrants per day. If the BCM user ’s CAPTCHA verification code fails the authenticity verification, the user is considered to be a malicious user of the blockchain technology platform. The user maliciously used the blockchain resources of the blockchain technology platform, resulting in blockchain resources. Waste. At this time, according to the user's malicious attack on the blockchain technology platform, the user is temporarily frozen to use the blockchain technology platform, or the user is permanently banned, and the user is no longer provided with the blockchain technology platform area. Blockchain resources.

Conversion of BCM warrants into transaction fees:

BCM warrants spent by BCM users using BCM non-transaction service resources will be transferred to the blockchain nodes that provide services. Each block cycle, the system measures the workload according to the BCM warrants received by each blockchain node, so as to issue a corresponding number of token rewards. This part of the reward is the transaction fee income of the blockchain nodes.

When a blockchain node provides non-transaction service resources for BCM, the BCM warrant obtained is the proof of workload of the blockchain node. The system issues transaction fees for blockchain nodes based on workload. Assume that in a packaging cycle, a total of Qtotal BCM warrants flow from BCM users to the underlying blockchain, and a worker ring node Wnode receives Qwnode BCM warrants. The total transaction fee issued by the system is T tokens. Then, the transaction fee that the worker ring node Wnode can get is determined by the following formula:

Tx = (Qwnode / Qtotal) * T

Among them, Tx is the transaction fee obtained by the blockchain node.

The above-mentioned method for controlling the use of blockchain resources based on the blockchain system can not only effectively prevent the abuse of blockchain resources, but also can provide a measure for the workload of blockchain nodes for a specific application service, reducing the system. Technical pressure in terms of preventing user cheating and measuring workload of blockchain nodes.

The application also provides a block chain resource use control device based on a block chain system. The blockchain system includes a blockchain technology platform and a blockchain application. The blockchain technology platform includes several blockchain nodes for providing basic functions to the blockchain application; the blockchain application is developed based on the basic functions provided by the blockchain technology platform; the area When a blockchain application runs, the blockchain resources of the blockchain technology platform are used. For the blockchain system, see FIG. 2 and the related description of FIG. 2 described above.

As shown in FIG. 6, in an embodiment, the device for controlling the use of blockchain resources includes a first issuing module 11, a deduction module 22, a verification module 33, a second issuing module 44 and a prohibition module 55.

The first issuing module 11 issues a first preset number of warrants to users of the blockchain application; the warrants are paid to the blockchain when the user uses non-transaction service resources provided by the blockchain technology platform The virtual cost of the node. Warrants are consumption proofs that users consume non-transaction service resources provided by the blockchain technology platform and need to pay to the system. At the same time, the system also transfers the warrants consumed by users to the corresponding blockchain in the blockchain technology platform that provides non-transaction service resources node.

In this embodiment, the system issues a first preset number of warrants to users of the blockchain application so that the user pays each of the services provided in the blockchain technology platform when using non-transaction service resources in the blockchain resources Blockchain nodes. The first preset number of warrants may be determined according to the number of user-consumption warrants preset in a preset preset period of time.

The deduction module 22 is used to determine that when a user of the blockchain application uses the non-transaction service resources provided by the blockchain technology platform, a corresponding amount of the user's warrants is deducted according to the usage situation. In this embodiment, when the system detects that a user of a blockchain application uses a non-transaction service resource provided by a blockchain technology platform, the user will be deducted a corresponding number of warrants. The number of deducted warrants is directly proportional to the size of the non-transaction service resource used by the user. Deducting the corresponding number of warrants of the user according to the use situation may be: determining the number of users using the non-transaction service resource according to a preset calculation method, and then determining the deduction according to the relationship between the number of non-transaction service resources and the number of warrants The number of warrants.

For example, in one embodiment, the blockchain application is an instant messaging application, and the non-transaction service resource is the amount of data generated by a user sending a message through the instant messaging application. When the user sends a preset number of messages to generate a corresponding amount of data, the number of blockchain resources consumed by the blockchain technology platform, here is the number of the non-transaction service resources, so as to calculate the user sent through the instant messaging application The relationship between the amount of data generated by the message and the number of non-transaction service resources. Further, according to the relationship between the amount of data generated by the user sending the message through the instant messaging application and the number of consumed warrants, the warrants deducted when the user uses the non-transaction service resources provided by the blockchain technology platform are determined quantity.

The verification module 33 is configured to verify the authenticity of the identity of the user when it is detected that the user's possession of the blockchain application is zero. In this embodiment, when a user of a blockchain application uses the blockchain application, the non-transaction service resources provided by the blockchain technology platform are indirectly used. Each use consumes a corresponding number of warrants. Under normal circumstances, the system issues the number of warrants to users of the blockchain application within a preset period of time to meet the normal use of the users of each blockchain application within the preset period of time. However, if there is a malicious attack on the blockchain technology platform among the users of the blockchain application, if the blockchain resources are abused by using the blockchain application, the user's warrants will be quickly consumed within the preset time period. Finish.

The second issuing module 44 is configured to issue a second preset number of warrants to the user if the identity of the user passes the authenticity verification. When the users of the blockchain application have zero warrants, they may be maliciously attacking the users of the blockchain technology platform. For example, in the process of the server forming a blockchain node through "mining", the "mining" successful server becomes a blockchain node in the blockchain technology platform. However, when a "mining" unsuccessful server cannot become a blockchain node, it is likely to maliciously attack the blockchain technology platform, causing abuse and waste of blockchain resources in the platform. At the same time, it is not ruled out that some users of blockchain applications cause excessive use of warrants according to demand, resulting in warrants being zero for a preset time. Therefore, it is necessary to verify the authenticity of the user with zero warrants.

The prohibition module 55 is used to prohibit the user from using the non-transaction service resource provided by the blockchain technology platform if the identity of the user has not passed the authenticity verification. If the identity of the user of the blockchain application fails to verify the authenticity of the system, it means that the user is a user who maliciously attacks the blockchain technology platform, and the system will prohibit the user from subsequently using all the blockchain technology platform Describe non-transaction service resources. The prohibition may be to temporarily freeze the user. For example, the user is prohibited from using the non-transaction service resource provided by the blockchain technology platform within a preset period of time. It may also be that the user is permanently prohibited from using the non-transaction service resources provided by the blockchain technology platform. The prohibited manner may be determined according to the user's use of the non-transaction service resource.
