Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The method provided by the embodiment of the invention (for convenience of description, the method provided by the embodiment of the invention can be abbreviated as the method) can be applied to each block chain network, and the management efficiency of the block chain network nodes can be improved. Referring to fig. 1, fig. 1 is a block chain network node structure diagram according to an embodiment of the present invention. In fig. 1, the blockchain network 20 may be a blockchain network applied in any field, and may be determined according to an actual application scenario, which is not limited herein. The node 10b, the node 10c, the node 10d, the node 10e, and the node 10f are part of nodes in the blockchain network 20, and each node is connected to other nodes in the blockchain network 20 based on the node configuration information of the node to implement functions such as data transmission.

The node 10a is configured based on the node configuration information of the node 10a, and each node is configured based on the updated node configuration information of each node, so that the node 10a is connected with each node, and the purpose of adding the node 10a to the blockchain network 20 is achieved.
Referring to fig. 2, fig. 2 is a flow chart illustrating a method for managing nodes of a blockchain network according to an embodiment of the present invention. As shown in fig. 2, the method for managing a node of a blockchain network according to an embodiment of the present invention may include the following steps S101 to S104.
S101, when a node adding request is received, node information of a first node and a specified block chain network identifier carried by the node adding request are obtained.
In some feasible embodiments, after receiving the node addition request, node information of the first node carried in the node addition request may be obtained, where the node information of the first node includes a communication information protocol used by the first node to communicate with other nodes in the blockchain network, a node identifier of the first node, communication address information of the first node, and node port information of the first node, where the node port information includes a port type, a port connection mode, and the like, and may be specifically determined according to an actual application scenario, which is not limited herein. It should be particularly noted that the node addition request may be a request triggered when a device such as a server and a physical machine corresponding to the first node is accessed into the blockchain network, or may be a request triggered when the device such as the server and the physical machine corresponding to the first node is configured for the first node after being accessed into the blockchain network, and a specific triggering manner of the node addition request may also be determined based on an actual application scenario, which is not limited herein. It should be noted that, after the device such as the server and the physical machine corresponding to the first node is accessed to the blockchain network, since the first node and each node in the blockchain network are not configured, the first node is only accessed to the blockchain network, but does not have any role in the blockchain network.
Optionally, when there are multiple blockchain networks in an application scenario, the node addition request may carry a specified blockchain network identifier when triggered, so as to determine, based on the specified blockchain network identifier carried in the node addition request, a corresponding blockchain network to which the first node is to access. The specified network identifier of the block chain may be a marking information for marking the network of the block chain, which is obtained by combining one or more of numbers, letters, chinese characters, and special characters, and may be determined according to an actual application scenario, which is not limited herein.
S102, validity verification is conducted on the node information of the first node, and when the node information of the first node is valid information, the node information and the node configuration information of each node in the block chain network corresponding to the specified block chain network identification are obtained.
In some possible embodiments, after the node information of the first node carried in the node addition request is obtained, validity verification may be performed on the node information of the first node. Optionally, the node information of the first node may be sent to a consensus node in the blockchain network corresponding to the specified blockchain network identifier carried in the node addition request, so that the consensus node in the blockchain network verifies the node information of the first node based on a preset verification manner. And generating a signature confirmation message after any consensus node in the block chain network passes the verification of the node information of the first node. At this time, signature confirmation messages sent by a plurality of consensus nodes in the block chain network may be received, and when each received signature confirmation message satisfies a preset consensus policy, the node information of the first node may be determined to be valid information. The preset verification mode may be to verify whether the device number and the device type corresponding to the first node carried in the node information are preset devices or preset device types, or whether the node information is legal information, and the specific preset verification mode may be determined based on an actual application scenario, which is not limited herein.
The preset consensus strategy may be that the node information of the first node is considered to be valid information after a certain proportion of consensus nodes in all the consensus nodes in the block chain network verify the node information of the first node, for example, the node information of the first node is considered to be valid information after a signature confirmation message sent by ninety-five percent of the consensus nodes is received. Or, the preset consensus strategy may be that when receiving a signature confirmation message sent by a plurality of consensus nodes in the blockchain network, determining whether the consensus node sending the signature confirmation message belongs to a preset consensus node based on a signature in the signature confirmation message, and considering the node information of the first node as valid information when the consensus node sending the signature confirmation message is the preset consensus node and/or the consensus node sending the signature confirmation message exceeds all the consensus nodes in the blockchain network by a certain ratio. Therefore, the preset consensus strategy can also be determined based on actual application scenarios, and is not limited herein.
In some possible embodiments, after determining that the node information of the first node is valid information, node information and node configuration information of each node in the blockchain network may be acquired, so as to configure a connection manner, a connection relationship, and the like of the first node and each node in the blockchain network to add the first node to the blockchain network.
S103, generating node configuration information of the first node based on the node information of each node in the block chain network, and sending the node configuration information of the first node to the first node.
In some possible embodiments, after obtaining the node information of each node in the blockchain network, the node configuration information of the first node may be generated based on the node information of each node in the blockchain network, where the node information of each node in the blockchain network also includes a communication information protocol used for communicating with other nodes in the blockchain network, a node identifier of the first node, communication address information of the first node, and node port information of the first node, where the node port information includes a port type, a port connection manner, and the like, and may be specifically determined according to an actual application scenario, which is not limited herein. After the node configuration information of the first node is generated, the node configuration information of the first node may be sent to the runtime environment, the runtime totality, or the node management platform of the first node based on the communication address information and/or the node identifier of the first node, so that the runtime environment, the runtime totality, or the node management platform of the first node configures the first node. Optionally, when the first node operates based on the container, the node configuration information of the first node may be sent to the information forwarding platform, and the information forwarding platform obtains the communication address information of the first node and the node identifier of the first node, which are included in the node configuration information of the first node, so that the node configuration information of the first node is sent to the container, the device, the physical machine and the like corresponding to the first node based on the communication address information of the first node and/or the node identifier of the first node, and the first node is configured according to the node configuration information of the first node.
Specifically, referring to fig. 3, fig. 3 is a schematic view of a scenario for generating node configuration information according to an embodiment of the present invention. As shown in fig. 3, it is assumed that the blockchain network includes three nodes, node a, node B and node C, and node D is the first node, i.e., node a is the node to be added to the blockchain network. After the node information a of the node a, the node information B of the node B, and the node information C of the node C are obtained, the node configuration information of the node D may be generated based on the node information a, the node information B, and the node information C, where the node configuration information of the node D may be used to configure a communication mode, a port connection mode, establish a communication address connection, and the like between the node D and the node a, the node C, and may be specifically determined based on specific information content and an actual application scenario in actual node information, which is not limited herein. Therefore, after the node configuration information of the node D is generated based on the above implementation, the node configuration information of the node D may be sent to an operation tool of the node D, such as a docker container, a node management platform corresponding to the node D, and the like, to complete configuration of the node D.
In some possible embodiments, when the node addition request carries a specified routing identifier, a specified routing node may be determined from the blockchain network based on the specified routing identifier carried in the node addition request and route information of the specified routing node is obtained, and then a node (for the purpose of description, hereinafter referred to as a fourth node) connected to the target node based on the specified routing node may be determined based on the route information. That is, if the first node is added to the blockchain network, the first node is connected to the first node through the designated routing node. At this time, the routing information of the designated routing node and the node information of the fourth node may be used to generate the node configuration information of the first node, and the first node may be configured to be added to the blockchain network based on the node configuration information of the first node. The fourth node may be any service node, contract node, and the like connected to the first node based on the routing node, and may be specifically determined based on an actual application scenario, which is not limited herein.
S104, adding the node information of the first node to the node configuration information of each node in the block chain network to obtain first updated node configuration information of each node, and sending the first updated node configuration information of each node to the corresponding node in the block chain network.
In some possible embodiments, while the node configuration information of the first node is generated, the node information of the first node (the communication information protocol of the first node, the node identifier of the first node, the communication address information of the first node, and the node port information of the first node) may be added to the node configuration information of each node in the blockchain network, so as to update the node configuration information of each node, and obtain updated node configuration information of each node in the blockchain network. Therefore, the node configuration information of each node in the block chain network can be sent to the operating environment, the operating tool or the node management platform corresponding to each node, so that the operating environment, the operating tool or the node management platform of each node configures the first node. Optionally, when each node in the block chain network operates based on a container (each node corresponds to one container), the updated node configuration information of each node may be sent to the information forwarding platform, and the information forwarding platform obtains the communication address information of each node and the node identifier of each node included in each updated node configuration information, so that the updated node configuration information of each node is sent to the container, the device, the physical machine and the like corresponding to each node based on the communication address information of each node and/or the node identifier of each node to configure each node.
Referring to fig. 4, fig. 4 is a schematic view of a scenario for updating node configuration information according to an embodiment of the present invention. As shown in fig. 4, it is assumed that the blockchain network includes three nodes, i.e., node a, node B, and node C, and node D is the first node, i.e., node a is the node to be added to the blockchain network. After the node configuration information a of the node a, the node configuration information B of the node B, and the node configuration information C of the node C are acquired, the node information of the node D may be added to the node configuration information a, the node configuration information B, and the node configuration information C to update the node configuration information a, the node configuration information B, and the node configuration information C. The first updated configuration information of any one of the three nodes, node a, node B, and node C, may be used to configure a communication mode and a port connection mode between the corresponding node and node D, establish a communication address connection, and the like, and may be determined based on the actual node configuration information, specific information content in the node information of node D, and an actual application scenario, which is not limited herein.

S205, when the node deletion request is received, the node information of the second node carried by the node deletion request is obtained, and the second node is determined and deleted from the block chain network based on the node information of the second node.
In some feasible embodiments, after receiving the node deletion request, node information of the second node carried in the node deletion request may be acquired, where the node information of the first node includes a communication information protocol used by the second node to communicate with other nodes in the blockchain network, a node identifier of the second node, communication address information of the second node, and node port information of the second node, where the node port information includes a port type, a port connection mode, and the like, and may be specifically determined according to an actual application scenario, which is not limited herein. It should be particularly noted that the node deletion request may be a request triggered when a device such as a server and a physical machine corresponding to the second node is removed from the blockchain network, and a specific triggering manner may also be determined based on an actual application scenario, which is not limited herein. Therefore, after receiving the node deletion request, the second node may be determined from the blockchain network based on the node information of the second node carried in the node deletion request, and the second node may be deleted from the blockchain network. Optionally, the node deletion request may further carry a specified node identifier, and after the node deletion request is received, the specified node identifier carried in the node deletion request may be acquired to determine, from the blockchain network, a second node marked by the specified node identifier, and delete the second node from the blockchain network.

In some possible embodiments, after the device such as the server and the physical machine corresponding to the second node is removed from the blockchain network, when each node in the blockchain network is involved in information communication and data transmission, since the node configuration information of other nodes in the blockchain network except the second node also stores the node information of the second node, an error may occur in the operation of the blockchain network. Therefore, after the second node is deleted from the blockchain network, the other nodes except the second node in the blockchain network need to be reconfigured so that the blockchain network can work normally after the second node is deleted.
Specifically, the node information of the second node may be deleted from the node configuration information of the other nodes except the second node in the blockchain network to obtain updated node configuration information of the other nodes except the second node, and the updated node configuration information of the other nodes except the second node is sent to the corresponding node (an operation tool of the node, such as a docker container, a node management platform corresponding to the node, and the like) in the blockchain network, so as to update the connection state, the connection mode, and the like of the other nodes except the second node in the blockchain network again based on the updated node configuration information, so as to eliminate a node configuration error caused by the node information of the second node. Optionally, when each node in the blockchain network operates based on a container, the node configuration information of the other nodes except the second node may be sent to the information forwarding platform, and the information forwarding platform acquires the communication address information and the node identifier of the other nodes except the second node, which are included in the node configuration information of the other nodes except the second node, so that the node configuration information of the other nodes except the second node is sent to containers, devices, physical machines and the like corresponding to the other nodes except the second node based on the communication address information and/or the node identifier of the other nodes except the second node, and the other nodes except the second node are configured according to the node configuration information of the other nodes except the second node.
Referring to fig. 6, fig. 6 is a schematic view of a scenario for deleting a node from a blockchain network according to an embodiment of the present invention. In fig. 6, it is assumed that the blockchain network includes a node a, a node B, a node C, and a node D, and at this time, if the node D is to be deleted from the blockchain network, the node information D of the node D may be deleted from the node configuration information a of the node a, the node configuration information B of the node B, and the node configuration information C of the node C, so as to obtain updated node configuration information a, updated node configuration information B, and updated node configuration information C. And then the updated node configuration information B of the node a, the updated node configuration information B of the node B, and the updated node configuration information C of the node C are respectively sent to the node a, the node B, and the node C (an operation tool of the node, such as a docker container, a node management platform corresponding to the node, and the like) to reconfigure other nodes (the node a, the node B, and the node C) in the block chain network except the node D.

The first routing node connected with the second node can be determined, the routing information and the routing configuration information of the first routing node are obtained, and a third node is determined from other nodes except the second node in the block chain network. The third node may be one or more nodes closest to the second node in the blockchain network, may also be one or more nodes not connected with the routing node or less connected with the routing node in the blockchain network, and may also be a standby node for receiving the transition routing information in the blockchain network, which may be specifically determined based on an actual application scenario, and is not limited herein.
After the second node is deleted from the blockchain network, the routing information of the first routing node may be added to the node configuration information of the third node, so as to obtain third updated node configuration information of the third node. Meanwhile, the node information of the second node may be deleted from the routing configuration information of the first routing node, and the node information of the third node is added to the routing configuration information of the first routing node, so as to obtain the first updated routing configuration information of the first routing node.

In some feasible embodiments, each node in the blockchain network may also be detected in real time, and when it is detected that any node in the blockchain network is an invalid node, the node information of the invalid node is obtained, the invalid node is deleted, and the node information of the invalid node is deleted from the node configuration information of other nodes except the invalid node, so as to obtain fourth updated node configuration information of other nodes except the invalid node, and the fourth updated node configuration information of other nodes except the invalid node is sent to the corresponding node in the blockchain network. Optionally, when the real-time detection is performed on each node in the block chain network, the service life of the device, the physical machine, and the like corresponding to each node may be detected, and if the service life exceeds the preset service life, the corresponding node may be determined to be an invalid node. Or, when it is detected that each node cannot work normally, that is, when a device, a physical machine, or the like corresponding to the node fails, the node corresponding to the failed device, physical machine, or the like may be determined as an invalid node. In addition, the network state of each node can be detected, when the network condition cannot meet basic data transmission and information communication, the corresponding node can be determined to be an invalid node, and a specific detection mode can be determined based on an actual application scene, which is not limited herein.
In the embodiment of the invention, the node information carried in the node adding request is validated, so that the accuracy of the node management of the block chain network can be improved, and the stability of the work of the block chain network can be maintained. The node configuration information of the first node is generated based on the node information of each node in the block chain network, and the node information of the first node is added to the node configuration information of each node in the block chain network to obtain first updated node configuration information of each node, so that all nodes and the first node in the block chain network can be configured based on the first updated node configuration information and the configuration information of the first node, the first node is added to the block chain network, and the efficiency of adding a new node to the block chain network is improved.
