Description

Block chain domain triggering method and system

technical field

The embodiments of the present disclosure relate to the field of communication technologies, and in particular, to a method and system for triggering blockchain domain division.

Background technique

Based on P2P transmission, consensus mechanism, encryption algorithm, block chain data structure, distributed data storage and other technologies, the blockchain (Block Chain) realizes a decentralized trusted digital architecture. The core of the blockchain is decentralization, with point-to-point transmission as the carrier, using distributed node consensus algorithms, encryption algorithms, and block chain data structures to generate non-tamperable and unforgeable distributed ledgers. However, because of its idea of decentralization, there will be data traffic such as broadcast messages, consensus algorithm messages, and data block synchronization between any two nodes. When the number of blockchain network nodes reaches a certain scale, the surge in data traffic will bring greater pressure to the transmission network, and at the same time, each node will also face the pressure of calculation.

In order to solve the above problems, a block chain domain division method is currently adopted. When the number of blockchain nodes reaches a certain scale, all nodes are split into two different domains. The broadcast and consensus algorithm between nodes in this domain The message is limited to this domain and will not spread to other domains. However, when a new bookkeeping occurs, the data block will be synchronized across domains. If the number of nodes in this domain reaches the domain division standard, the domain will be divided again, and so on. , the purpose of reducing network traffic and reducing the amount of calculation of nodes can be achieved through domain division.

However, it is unreasonable to use a single static factor such as the number of nodes as a condition to trigger blockchain domain division, and it is difficult to achieve efficient and reasonable blockchain domain division.

Step 11. When the first node joins the blockchain network, obtain the current load parameters of each second node in the blockchain network.

Step 12. Calculate the current overall load parameters of the blockchain network according to the current load parameters of each second node.

Step 13. Determine whether the current overall load parameter of the blockchain network is greater than the pre-acquired trigger domain load threshold. If so, trigger the domain division process and complete the joining of the first node. If not, do not trigger the domain division process and complete the first Joining of nodes.

In the embodiment of the present disclosure, the first node is a new node of the blockchain network, and each second node is an existing node in the blockchain network. In step 11, when the new node (first node) joins the block In the blockchain network, the current load parameters of each node (second node) existing in the blockchain network are obtained. Wherein, the current load parameter of the second node refers to the latest load parameter of the second node.

In some embodiments, step 11 includes: when the first node joins the blockchain network, obtaining a blockchain load information table from a second node adjacent to the first node.

In some embodiments, the second node adjacent to the first node is the node (second node) that the first node connects to for the first time when it joins the blockchain network. In the blockchain network, each second node stores and maintains a blockchain load information table of the blockchain network.

Wherein, the blockchain load information table at least includes a node load information table, and the node load information table includes the following fields: current load parameters (latest load parameters) of each second node. In some embodiments, the node load information table further includes the following fields: the node serial number of each second node and the node address of each second node. In the embodiment of the present disclosure, the node load information table may further include other information of the corresponding second node, which will not be listed here.

In some embodiments, the current load parameter of the second node Node_Load=CPU_Load*W_C+Memory_Load*W_M, wherein, Node_Load is the current load parameter of the second node, CPU_Load is the current CPU average resource utilization rate of the second node, W_C is the preset weight corresponding to CPU_Load, Memory_Load is the current average memory resource utilization rate of the second node, W_M is the preset weight corresponding to Memory_Load, W_C, W_M∈(0,1), W_C+W_M=1. Among them, W_C is the weight of the average CPU resource utilization in the node load, which can be determined according to the degree of influence of the CPU of the second node on the performance of the second node; W_M is the weight of the average memory resource utilization in the node load The weight may be determined according to the influence degree of the memory of the second node on the performance of the second node. It should be noted that specific values of W_C and W_M may be determined according to actual conditions, and the embodiments of the present disclosure do not specifically limit the values of W_C and W_M.

In some embodiments, for each second node in the blockchain network, the second node updates the current load parameter of the second node every preset update time period. Specifically, the second node updates the current load parameter of the second node according to the above formula: Node_Load=CPU_Load*W_C+Memory_Load*W_M. Wherein, CPU_Load is the average CPU resource utilization rate of the second node within the current preset update time period, and Memory_Load is the average memory resource utilization rate of the second node within the current preset update time period. In the embodiment of the present disclosure, the preset update time period is the time period for the second node to calculate and update the current load parameter, which can be set according to actual needs, and is not limited in the embodiment of the present disclosure.

Among them, CPU_Load (current CPU average resource utilization rate) can be obtained and updated according to the following method: within the current preset update time period (for example, 30 minutes), every preset sampling time interval (for example, 1 minute), from the second node The resource utilization rate of the CPU is read in the operating system of the node machine, and the resource utilization rate of all CPUs read within the preset update time period (for example, 30 minutes) is averaged to obtain the current preset update rate of the second node.

Similarly, Memory_Load (the average resource utilization rate of the current memory) can be obtained and updated in the following manner: within the current preset update time period (for example, 30 minutes), every preset sampling time interval (for example, 1 minute), from the second Read the resource utilization rate of the memory in the node machine operating system of the node, calculate the average value of the resource utilization rate of all memory read within the preset update time period (for example, 30 minutes), and obtain the second node in the current preset Update the Memory_Load (memory average resource utilization) within the time period.

In some embodiments, for each second node in the blockchain network, after the second node updates its current load parameters in the above-mentioned manner, it updates its current load parameters in the node load information table stored by the second node , and send a node load update message to other second nodes in the blockchain network in a broadcast manner.

In step 13, if it is judged that the current overall load parameter of the blockchain network is greater than the pre-acquired trigger domain load threshold, the domain division process is triggered, and domain division messages are sent to the first node and each second node in the form of broadcast , the process of domain division is completed, and the first node successfully joins the blockchain network. If it is determined that the current overall load parameter of the blockchain network is less than or equal to the pre-acquired load threshold for triggering domain division, the domain division process is not triggered, and the first node successfully joins the blockchain network. After joining the blockchain network, the first node becomes the second node, and when a new node joins the blockchain network, repeat steps 11 to 13 above.
