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.
In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.
Fig. 1 is a flowchart illustrating a limiting method for creating a blockchain account in a blockchain system according to an embodiment of the present invention.
As shown in fig. 1, the limiting method for creating a blockchain account in the blockchain system includes the following steps:
The block chain system comprises a plurality of nodes, wherein when any node in the block chain system receives a broadcast packet sent by other nodes in the block chain system, the any node analyzes the broadcast packet to obtain the initiation time of operation in the broadcast packet and obtain the current time, then the initiation time and the current time are differenced to obtain the delay time of the broadcast packet sending, and the delay time is placed at the tail of a broadcast packet delay time queue stored by any node.
As an embodiment, the broadcast packet delay time queue is established after the initial node of the blockchain system starts and creates the created block, and is synchronized to each node in the blockchain system. That is, each node in the blockchain system has a broadcast packet delay time queue.
It should be noted that, before the initial node is connected to another node, no data exists in the broadcast packet delay time queue because no broadcast packet is received from another node.
That is, after the delay time is placed at the tail of the broadcast packet delay time queue stored in the node, it is determined whether the current length of the broadcast packet delay time queue exceeds the preset maximum length allowed by the queue.
As an embodiment, the maximum allowed length of the queue is a global constant, and the value represents the maximum length of the queue.
And 103, if the current length of the broadcast packet delay time queue exceeds the maximum length allowed by the queue, deleting the head data of the broadcast packet delay time queue, and calculating the current average delay time according to the sum of all delay times in the current broadcast packet delay time queue and the length of the current broadcast packet delay time queue.
As an embodiment, the above calculation formula of the current average delay time is: and the sum of all delay time in the current broadcast packet delay time queue/the length of the current broadcast packet delay time queue is equal to the current average delay time.
As an example, the maximum average delay time that can be tolerated by the blockchain system is a global variable, and the variable can be voted for change by the blockchain system using a consensus mechanism.
If the current average delay time is less than the maximum average delay time that the blockchain system can tolerate, a new blockchain account is allowed to be created, step 105.
As an embodiment, if the current average delay time is less than the maximum average delay time that can be tolerated by the blockchain system, the new account registration permission flag in the blockchain system is set to 1, allowing a new blockchain account to be created.
And 106, if the current average delay time is greater than or equal to the maximum average delay time tolerable by the blockchain system, forbidding the creation of a new blockchain account.
As an embodiment, if the current average delay time is greater than or equal to the maximum average delay time tolerable by the blockchain system, the new account registration permission flag in the blockchain system is set to 0, and creation of a new blockchain account is prohibited.
That is to say, in the embodiment of the present invention, when a new user connects to a blockchain node to initiate an operation of registering a new blockchain account, if the new account registration permission flag is set to 0, the registration request sent by the user is not permitted to connect to the new user; if the position of the new account registration permission flag is 1, the registration request sent by the access user is permitted, and normal registration can be carried out.
According to the limiting method for block chain account creation in the block chain system, when any node in the block chain system receives a broadcast packet, the broadcast packet is analyzed to obtain the initiation time of operation in the broadcast packet, the time difference between the current time and the initiation time is obtained to be used as delay time, the delay time is placed at the tail of a broadcast packet delay time queue stored by the node, whether the current length of the broadcast packet delay time queue exceeds the maximum length allowed by the queue or not is judged, the head data of the broadcast packet delay time queue is deleted when the current length of the broadcast packet delay time queue exceeds the maximum length allowed by the queue, the current average delay time is calculated according to the sum of all delay time in the current broadcast packet delay time queue and the length of the current broadcast packet delay time queue, and whether the current average delay time is smaller than the maximum average delay time tolerable by the block chain system or not is further judged Wherein if the current average delay time is less than the maximum average delay time tolerable by the blockchain system, then a new blockchain account is allowed to be created; and if the current average delay time is more than or equal to the maximum average delay time tolerable by the blockchain system, forbidding the creation of a new blockchain account. Therefore, the invention can judge whether the block chain account creating function is stopped or not by comparing the current average delay time with the maximum average delay time tolerable by the system, so that the account is limited to be increased endlessly under the condition of protecting the user scale of the block chain, thereby avoiding the network resources of the block chain system from being exhausted and greatly improving the network access quality of the block chain.
In order to further understand the above technical solution, the above technical solution will be described in detail by fig. 2.
Fig. 2 is a flowchart illustrating a restriction method for creating a blockchain account in a blockchain system according to an embodiment of the present invention.
As shown in fig. 2, the limiting method for creating a blockchain account in the blockchain system includes the following steps:
in step 201, node X receives broadcast packets from other nodes.
It should be noted that the blockchain system includes a plurality of nodes, and each node is connected to another node, wherein any node X can receive the broadcast packet transmitted from another node.
In step 202, node X parses the broadcast packet.
At step 203, node X obtains the initiation time of the operation within the packet.
In step 204, the node X makes a difference between the initiation time and the current time to obtain an operation delay time.
As an embodiment, the node X in the blockchain system makes a difference between the initiation time of the broadcast packet and the current time of receiving the broadcast packet, so as to obtain the delay time of the operation.
In step 205, the node X puts the delay time into the tail of the broadcast packet delay time queue stored in the node.
As an embodiment, the broadcast packet delay time queue is established after the initial node of the blockchain system starts and creates the created block, and is synchronized to each node in the blockchain system.
It should be noted that, before the initial node is connected to another node, no data exists in the broadcast packet delay time queue because no broadcast packet is received from another node.
As an embodiment, the maximum allowed length of the queue is a global constant.
And step 208, calculating the current average delay time according to the sum of all delay times in the delay time queue of the current broadcast packet and the length of the delay time queue of the current broadcast packet.
As an example, assume that all delay times in the time queue when broadcasting a packet are a1、a2...an(ii) a The length of the current broadcast packet delay time queue is n; the current average delay time is d; then the current average delay time
In step 209, it is determined whether the current average delay time is less than the maximum average delay time tolerable by the blockchain system. If so, go to step 210; if not, step 212 is performed.
As an example, the maximum average delay time that can be tolerated by the blockchain system is a global variable, and the variable can be voted for change by the blockchain system using a consensus mechanism.
At step 210, node X allows the connected user to send a registration request.
It should be noted that, when the current average delay time is less than the maximum average delay time tolerable by the blockchain system, the new account registration permission flag bit in node X is 1, and node X allows the connected user to send a registration request.
At step 212, node X does not allow the connected user to send a registration request.
It should be noted that, when the current average delay time is greater than or equal to the maximum average delay time tolerable by the blockchain system, the new account registration permission flag bit in the node X is 0, and the node X allows the connected user to send a registration request; i.e., forbid the creation of new blockchain accounts.
The request returns a failure, step 213.
According to the limiting method for block chain account creation in the block chain system, when any node in the block chain system receives a broadcast packet, the broadcast packet is analyzed to obtain the initiation time of operation in the broadcast packet, the time difference between the current time and the initiation time is obtained to be used as delay time, the delay time is placed at the tail of a broadcast packet delay time queue stored by the node, whether the current length of the broadcast packet delay time queue exceeds the maximum length allowed by the queue or not is judged, the head data of the broadcast packet delay time queue is deleted when the current length of the broadcast packet delay time queue exceeds the maximum length allowed by the queue, the current average delay time is calculated according to the sum of all delay time in the current broadcast packet delay time queue and the length of the current broadcast packet delay time queue, and whether the current average delay time is smaller than the maximum average delay time tolerable by the block chain system or not is further judged Wherein if the current average delay time is less than the maximum average delay time tolerable by the blockchain system, then a new blockchain account is allowed to be created; and if the current average delay time is more than or equal to the maximum average delay time tolerable by the blockchain system, forbidding the creation of a new blockchain account. Therefore, the invention can judge whether the block chain account creating function is stopped or not by comparing the current average delay time with the maximum average delay time tolerable by the system, so that the account is limited to be increased endlessly under the condition of protecting the user scale of the block chain, thereby avoiding the network resources of the block chain system from being exhausted and greatly improving the network access quality of the block chain.
In order to implement the foregoing embodiment, an embodiment of the present invention provides a computer-readable storage medium, on which a restriction program for use in creating a blockchain account in a blockchain system is stored, where the restriction program for use in creating a blockchain account in the blockchain system is executed by a processor to implement the restriction method for use in creating a blockchain account in the blockchain system.
According to the computer-readable storage medium of the embodiment of the invention, the restriction program during creation of the blockchain account in the blockchain system is stored, so that when the restriction program during creation of the blockchain account in the blockchain system is executed by the processor, the restriction method during creation of the blockchain account in the blockchain system is realized, therefore, the invention can judge whether to stop the function of creating the blockchain account by comparing the current average delay time with the maximum average delay time tolerable by the system, so that under the condition of protecting the user scale of the blockchain, the restricted accounts are increased endlessly, thereby avoiding the network resources of the blockchain system from being exhausted, and greatly improving the network access quality of the blockchain.

As an embodiment, the delay time calculating module 303 is further configured to, when the current length of the broadcast packet delay time queue does not exceed the maximum length allowed by the queue, directly calculate the current average delay time according to the sum of all delay times in the broadcast packet delay time queue and the current length of the broadcast packet delay time queue.
As an embodiment, the broadcast packet delay time queue is established after the initial node of the blockchain system starts and creates the created block, and is synchronized to each node in the blockchain system.
For one embodiment, the maximum allowed length of the queue is a global constant, and the maximum average delay time tolerable by the blockchain system is a global variable and can be voted for change by the blockchain system with a consensus mechanism.
According to the limiting device for block chain account creation in the block chain system of the embodiment of the invention, when any node in the block chain system receives a broadcast packet, the broadcast packet is analyzed through an analyzing module to obtain the initiation time of the operation in the broadcast packet, the time difference between the current time and the initiation time is obtained to be used as the delay time, the delay time is placed at the tail of a broadcast packet delay time queue stored by the node, whether the current length of the broadcast packet delay time queue exceeds the maximum length allowed by the queue or not is judged through a first judging module, then a delay time calculating module deletes the head data of the broadcast packet delay time queue when the current length of the broadcast packet delay time queue exceeds the maximum length allowed by the queue, and calculates the current average delay time according to the sum of all delay times in the current broadcast packet delay time queue and the length of the current broadcast packet delay time queue, and finally, judging whether the current average delay time is less than the maximum average delay time tolerable by the blockchain system or not through a second judgment, so that the limiting module allows the creation of a new blockchain account when the current average delay time is less than the maximum average delay time tolerable by the blockchain system, and forbids the creation of the new blockchain account when the current average delay time is more than or equal to the maximum average delay time tolerable by the blockchain system.
