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 method for distributing node loads in a blockchain system according to an embodiment of the present invention, where the method for distributing node loads in a blockchain system includes the following steps:
s101, configuring at least two function nodes and combining the at least two function nodes into a logic node, wherein the at least two function nodes have a data storage operation function, a network connection function and a user request function, and the logic node has unique identification information in a block chain network.
That is, the number of the functional nodes needs to be at least two, the at least two functional nodes are combined into one logical node, and the logical node has unique identification information in the blockchain network; the at least two functional nodes can realize data storage operation, establish network connection with other nodes and receive user request information.
As an example, the number of the functional nodes is two, and the connection between the functional nodes is established to combine the two functional nodes into one logical node, wherein one functional node is set as a data storage operation node with a data storage operation function, and the other functional node is set as a network connection node with a network connection function and a user request function, so that transactions which originally need to be processed by a single node are processed by the two functional nodes in a functional differentiation manner, and the load of the single node is reduced.
As another example, the number of functional nodes is three, and the three functional nodes are combined into one logical node; the three functional nodes are respectively a data storage operation node with a data storage budget function, a network connection node with a network connection function and a user request node with a user request receiving function; therefore, the three functional nodes are combined into one logic node, and the functions of the three functional nodes are differentiated, so that the operation load of a single node is reduced.
S102, when the logic node is in an active state, controlling a node with a network connection function in the logic node to open a port to wait for other nodes with the network connection function to connect, controlling a node with the network connection function in the logic node to try to establish a connection relation with nodes with the network connection function in other logic nodes based on a configured logic node list, controlling a node with a data storage operation function in the logic node to start block production based on an initial block producer list, and controlling a node with a user request function in the logic node to open a port to wait for a user task request data packet to be transmitted.
That is, when the state of the logical node is active, the node with the network connection function in the logical node is controlled to open the port, so that other nodes with the network connection function establish connection with the logical node through the open port; controlling a node with a network connection function in the logic nodes to try to establish a connection relation with nodes with the network connection function in other logic nodes based on the configured logic node list so as to establish connection with each logic node in the list through the node with the network connection function according to the logic node list; and then, controlling a node with a data storage operation function in the logic nodes to start block production according to the initial block producer list, and controlling a node with a user request function in the logic nodes to open a port so that a user can transmit a task through the opened port.
There are various ways to determine whether a logical node is in an active state, for example: when the number of the functional nodes is two, the two functional nodes send inquiry data packets to each other at intervals of preset time to inquire whether the mutual connection is normal, and when any one of the functional nodes receives information of response abnormity or the other node cannot be connected, the logical node is judged to be in a dormant state; or, the query data packet is sent only through one functional node according to the preset time, and when the functional node receives the information of response abnormity or another node does not receive the query data packet in the preset time, the logic node is judged to be in the dormant state.
In summary, according to the method for distributing node load in a blockchain system in an embodiment of the present invention, at least two functional nodes are configured, and the at least two functional nodes are combined into one logical node, where the at least two functional nodes have a data storage operation function, a network connection function, and a user request function, and the logical node has unique identification information in a blockchain network; then, when the logic node is in an active state, controlling a node with a network connection function in the logic node to open a port to wait for other nodes with the network connection function to connect, controlling a node with the network connection function in the logic node to try to establish a connection relation with nodes with the network connection function in other logic nodes based on a configured logic node list, controlling a node with a data storage operation function in the logic node to start block production based on an initial block producer list, and controlling a node with a user request function in the logic node to open a port to wait for the transmission of a user task request data packet; therefore, the functions of the single node are differentiated, so that the operation load of the single node is reduced, and the stability of the block chain system is improved.
As shown in fig. 2, in some embodiments, in the distributed node load method of the block chain system according to an embodiment of the present invention, when there are three at least two functional nodes, the three functional nodes are a data storage operation node, a network connection node, and a user request node, and the data storage operation node, the network connection node, and the user request node interact with each other; the specific way of judging whether the logic node is in an active state is as follows:
s201, any one of a data storage operation node, a network connection node and a user request node periodically sends an inquiry data packet to the other two nodes to inquire whether the connection between the nodes is normal or not; if any node receives two pieces of information with normal response, the logic node is judged to be in an active state; and if the any node receives at least one piece of information responding to the abnormity or cannot be connected with other nodes, judging that the logic node is in a dormant state.
That is, when the number of the functional nodes is three, the three functional nodes are respectively a data storage operation node, a network connection node and a user request node; the data storage operation node, the network connection node and the user request node are interacted in pairs; any one of the data storage operation node, the network connection node and the user request node can regularly send inquiry data packets to the other two functional nodes to inquire whether the mutual connection is normal or not; when the other two functional nodes receive the inquiry data packet, judging whether the connection with other functional nodes except the other functional nodes is normal or not, if so, responding to normal information, and if not, responding to abnormal information; then, if any node receives two pieces of information which respond normally, the logic node is judged to be in an active state; and if any node receives at least one piece of information responding to the abnormity or cannot be connected with other nodes, judging that the logic node is in a dormant state. Therefore, when abnormal connection occurs among all functional nodes in the logic nodes, the logic nodes are closed, and the normal operation of the block chain system is ensured.
In summary, according to the load distribution method of the block chain system in the embodiment of the present invention, any one of the data storage operation node, the network connection node, and the user request node periodically sends an inquiry packet to another two nodes to inquire whether the connections between the nodes are normal; if any node receives two pieces of information with normal response, the logic node is judged to be in an active state; if the arbitrary node receives at least one piece of information responding to the abnormity or can not be connected with other nodes, the logic node is judged to be in a dormant state; therefore, when abnormal connection occurs among all functional nodes in the logic nodes, the logic nodes are closed, and the normal operation of the block chain system is ensured.
As shown in fig. 3, in some embodiments, in the method for load balancing of a blockchain system according to an embodiment of the present invention, when a new logical node needs to access a blockchain network, the method for load balancing of the blockchain system further includes the following steps:
s301, a network connection node address set is configured on the network connection node in the new logic node, and after all the functional nodes in the new logic node are started, the network connection node in the new logic node is connected to the network connection node of the corresponding logic node in the blockchain network according to the configured network connection node address set, so that the new logic node is connected to the blockchain network.
That is, when a new logical node needs to access the blockchain network, a node address set with the network connection node function in the blockchain network to which the new logical node is to be connected is configured on the node with the network connection function in the new logical node, so that the new logical node establishes connection between the node with the network connection function and the node address set node according to the configured node address set; after all functional nodes of the new logic node are started, establishing connection between the nodes with the network connection function and the nodes in the node address set according to the configured node address set; to connect the new logical node to the blockchain network.
As shown in fig. 4, in some embodiments, in the method for distributing node load in a blockchain system provided in an embodiment of the present invention, when a user needs to submit a task request to a blockchain network, the method for distributing node load in a blockchain system further includes the following steps:
s401, obtaining a user request node to be transmitted, packaging and signing the task request, and transmitting the task request to the user request node to be transmitted.
That is to say, when a user needs to transmit a task request into the blockchain system, a user request node to be transmitted is obtained first, and then the task request is packaged and signed and then is transmitted to the user request node to be transmitted.
There are various ways to obtain the user request node to be transmitted.
As an example, the user selects the user request node to be introduced according to the user request node address set issued by the block chain system official website, it should be noted that the state of each user request node (for example, the connection signal strength between the user node and each user request node, the computing capability of each user request node, the idle state, and the like) may be shown in the user request node address set issued by the system official website, so that the user selects the user request node to be introduced according to the state of each user request node.
It should be noted that the task request packaging and signing means that a user packages a task request to be transmitted through a blockchain system and signs the packaged task request through a private key owned by the user, so as to ensure the security of task request transmission.
S402, the user request node to be transmitted analyzes the user task request data packet based on the user public key to obtain the task request.
That is to say, after the user request node to be transmitted receives the task request data packet with the packed signature, the public key corresponding to the user private key is used for analyzing the task request data packet to obtain the task request.
And S403, forwarding the task request to a data storage operation node in the corresponding logic node, and forwarding the task request to a network connection node in the corresponding logic node, so that the task request is broadcasted in the block chain network through the network connection node in the corresponding logic node.
That is to say, after the user request node analyzes the task request data packet and obtains the task request, the user request node forwards the task request to the data storage operation node in the corresponding logic node, so that the logic node processes the task request when having the accounting right; meanwhile, the user request node also forwards the task request to a network connection node in the corresponding logic node so as to broadcast the task request in the blockchain network.
S404, when the corresponding logic node has the accounting right, the data storage operation node in the corresponding logic node stores the task request and performs operation.
That is to say, after receiving the task request forwarded by the user request node, the data storage operation node determines whether the logic node where the data storage operation node is located has the accounting right, and when the determination result is yes, the data storage operation node stores and operates the task request.
As shown in fig. 5, in some embodiments, in the distributed node load method of the blockchain system according to embodiments of the present invention, when a network connection node in any one of the logical nodes in the blockchain network receives a broadcast packet, where the broadcast packet includes a blockchain synchronization packet and a task request packet; the method for distributing node loads in the block chain system further comprises the following steps:
s501, the network connection node in the logic node forwards the broadcast data packet to the data storage operation node in the logic node.
S502, when the data storage operation node determines that the broadcast data packet is a block synchronization packet, step S503 is executed, and when the broadcast data packet is determined to be a task request packet, step S504 is executed.
That is, when receiving the broadcast data packet, the data storage operation node determines the type of the broadcast data packet, and determines that the broadcast data packet is a block synchronization packet or a task request packet, so as to perform different processing on different broadcast data packets.
And S503, directly storing the block synchronization packet by the data storage operation node in the logic node.
That is, when the broadcast data packet is a block synchronization packet, the data storage operation node directly stores the block synchronization packet, so that each logical node synchronously updates the block chain file.
S504, judge whether the logical node has the block production right, and when the judged result is yes, the data storage operation node in the logical node carries on the block production according to the task request in the task request packet.
That is, when the broadcast data packet is a task request packet, it is determined whether the logical node has a block production right, and when the determination result is yes, the data storage operation node in the logical node performs block production according to the task request in the task request packet.
There are various ways to determine whether a logical node has a block production right.
As an example, a block production right identifier is allocated to a logical node having a block production right by allocating the block production right identifier, and the block production right identifier is stored by a data storage operation node; when the data storage operation node receives a task request packet forwarded by the network connection node, judging whether a block production right identifier is stored in the data storage operation node, if so, judging that a logic node corresponding to the data storage operation node has a block production right.
The data storage operation node performs block production according to the task request in the task request packet, namely, the data storage operation node performs storage and operation on the task request according to the task request in the task request packet, and generates a block after a preset condition is reached.
As shown in fig. 6, in some embodiments, in the distributed node load method of the blockchain system provided by the present invention, a blockchain producer triggers a dpss blockchain producer voting event generation through a blockchain network, and each logical node in the blockchain network participates in voting as a whole to compete for blockchain production rights, wherein when a blockchain production condition is triggered, the distributed node load method of the blockchain system further includes the following steps:
s601, the data storage operation node in the logic node with the block production right performs task recording and block production to generate a synchronous block.
That is, when the tile production condition is triggered, the data storage operation node in the logical node having the tile production right records the task and packages the task after the previous tile timeline to generate the sync tile.
Among them, there are various ways to trigger the block production conditions, for example; through the preset block production time, when the interval between the previous block time line and the current time reaches the preset block production time, triggering a block production event; or, the task storage quantity of each block is preset, and when the task quantity after the last block timeline in the block chain system reaches the preset task storage quantity of each block, a block production event is triggered.
S602, the synchronization block is forwarded to a network connection node in the logical node having the block production right.
That is, after the data storage operation node in the logical node having the block production right packages the task and generates the synchronization block, the synchronization block is forwarded to the network connection node in the corresponding logical node.
S603, the network connection node in the logical node with block production right packs the synchronization blocks into block synchronization packets and broadcasts the block synchronization packets in the block chain network.
That is, after receiving the synchronization block sent by the data storage operation node, the network connection node in the logical node with block production right packages the synchronization block into a block synchronization packet, and broadcasts the block synchronization packet into the blockchain network, so that other logical nodes perform block chain synchronization according to the block synchronization packet.
To achieve the above embodiments, an embodiment of the present invention provides a computer-readable storage medium, on which a distributed node load program of a blockchain system is stored, and when executed by a processor, the distributed node load program of the blockchain system implements the above distributed node load method of the blockchain system.
To achieve the above embodiments, the present invention provides a distributed node loading apparatus of a blockchain system, as shown in fig. 7, the distributed node loading apparatus of the blockchain system includes: a configuration module 10 and a load distribution module 20.
The configuration module 10 is configured to configure at least two functional nodes, and combine the at least two functional nodes into one logical node, where the at least two functional nodes have a data storage operation function, a network connection function, and a user request function, and the logical node has unique identification information in a blockchain network
