The application provides a method for accessing a block chain system by an external node.
Referring to fig. 1 and fig. 2, fig. 1 is a flowchart illustrating a first embodiment of the present application, and fig. 2 is a structural diagram illustrating a block chain system of the present application, where proxy p represents a proxy node, bootNode represents a seed node server, and validator represents a node for block extraction and voting in a block chain.
In a first embodiment, the method is applied to a seed node server in a blockchain, and may include the following steps:
step S101: and receiving an access request sent by a first external node, wherein the access request is used for requesting access to the blockchain system, and the first external node is a node which is not accessed to the blockchain system.
In practical applications, the seed node server may receive the access request sent by the first external node, and then the seed node server may perform an access operation on the first external node based on the access request.
Step S102: node information of a proxy node in a blockchain system and an external node having access to the blockchain system is obtained.
In practical application, the method for selecting the seed node server in the blockchain system may be determined according to actual needs, for example, a node satisfying a preset performance requirement in the blockchain system is used as the seed node server. After the seed node server is selected from the block chain system, the seed node server can acquire node information of the agent node in the block chain system and the external node accessed to the block chain system, specifically, the seed node server can acquire the agent node in the block chain system first and then acquire the information of the external node accessed to the block chain system through inquiring the agent node; in addition, for convenience of management, the seed node server may further store node information of the proxy node and the external node accessed to the blockchain system in a kbucket or db, and then may manage the node information by using the kbucket or db.
Step S103: based on the node information, a set of target nodes is selected from the proxy node and the external nodes that have access to the blockchain system.
In practical application, the seed node server may select a target node set from the proxy node and the external node accessed to the blockchain system based on the node information as needed, that is, the target node set may only include the proxy node, may only include the proxy node accessed to the blockchain system, and may include both the proxy node and the proxy node accessed to the blockchain system; correspondingly, the first external node can be accessed into the blockchain system through the proxy node, and can also be accessed into the blockchain system through the external node accessed into the blockchain system, so that the first external node is not limited to be accessed into the blockchain system through the proxy node any more, the flexibility of accessing the blockchain system by the first external node is improved, and the service pressure of the proxy node is reduced; in addition, the external nodes accessed to the block chain system can increase the difficulty of attacking the agent nodes by malicious external nodes, and the safety degree of the agent nodes is improved. It should be noted that the number of nodes in the target node set may be determined according to actual needs, for example, the target node set may include only one node.
In a specific application scenario, in order to enable a first external node to access a blockchain system through a proxy node and enable not all first external nodes to access the blockchain system through the proxy node, when a seed node server selects a target node set from the proxy node and the external nodes which have accessed the blockchain system, the seed node server may first select the target proxy node set from the proxy node; selecting a target accessed external node set from external nodes accessed to the block chain system; and finally, taking the target agent node set and the target accessed external node set as a target node set.
In a specific application scenario, in order to improve the efficiency of selecting a target node set, when a seed node server selects the target node set from a proxy node and an external node accessed to a blockchain system, a preset number of nodes may be randomly selected from the proxy node and the external node accessed to the blockchain system as the target node set.
In a specific application scenario, in order to balance the performance of the blockchain system or the proxy node, when the seed node server selects the target node set from the proxy node and the external node accessed to the blockchain system, the target node set may be selected from the proxy node and the external node accessed to the blockchain system based on the performance requirement of the proxy node and/or the blockchain system. Specifically, when the service pressure of the proxy node is large, the target node set may be selected only from the external nodes that have accessed the blockchain system.
Step S104: and sending the information of the target node set to the first external node so that the first external node accesses the block chain system based on the information of the target node set through the DHT algorithm.
In practical application, after the seed node server selects the target node set, the information of the target node set can be sent to a first external node; it should be noted that, since the DHT algorithm may enable the first external node to be responsible for a small-range routing and for storing a small portion of data without a server, after the first external node is connected with the target node through the DHT algorithm, subsequent other nodes may access the block chain through the first external node.
The method for accessing the block chain system by the external node is applied to a seed node server in the block chain system, and is used for receiving an access request sent by a first external node, wherein the access request is used for requesting to access the block chain system, and the first external node is a node which does not access the block chain system; acquiring node information of an agent node in a blockchain system and an external node accessed to the blockchain system; selecting a target node set from the agent node and the external node accessed to the block chain system based on the node information; and sending the information of the target node set to the first external node so that the first external node accesses the block chain system based on the information of the target node set through the DHT algorithm. In the method for accessing the external node into the blockchain system, the seed node server obtains node information of the proxy node in the blockchain system and the external node accessed into the blockchain system, and based on the node information, the target node set is selected from the proxy node and the external node accessed to the blockchain system, that is, the target node set may include the proxy node or the external node accessed to the blockchain system, so that when the first external node accesses the blockchain system based on the information of the target node set through the DHT algorithm, the block chain can be accessed through the proxy node or the external node accessed to the block chain system, the aim of relieving the service pressure of the proxy node through the DHT algorithm and the external node accessed to the block chain system is achieved, and the performance influence on the block chain system when the external node is accessed can be reduced.
In the first embodiment, in order to improve the efficiency of the seed node server in acquiring the node information, and in order to improve the success rate of the first external node accessing the blockchain system through the external node accessed to the blockchain system, the seed node server may acquire the node information of the proxy node first when acquiring the node information of the proxy node in the blockchain system and the node information of the external node accessed to the blockchain system; and then acquiring node information of the external node which is connected to the blockchain system by the proxy node through the DHT algorithm.
In the first embodiment, after the first external node accesses the block chain based on the target node set, the block chain may not be accessed, at this time, the first external node may send corresponding node request information to the seed node server, so as to obtain a new target node set through the seed node server, and accordingly, after the seed node server sends information of the target node set to the first external node, it may also be determined whether the node request information sent by the first external node is received, and if so, the steps of selecting the target node set and the subsequent steps from the proxy node and the external node that has accessed the block chain system are performed.
In the first embodiment, the triggering condition for the seed node server to select the target node set may be determined by the first external node, for example, when the first external node needs to access the blockchain, the first external node sends corresponding information to the seed node server to trigger the seed node server to perform an action of selecting the target node set, and accordingly, after the seed node server obtains node information of the proxy node in the blockchain system and the external node that has accessed the blockchain system, before the proxy node and the external node that has accessed the blockchain system select the target node set, the seed node server may further determine whether to receive access request information sent by the first external node, and if so, perform steps of selecting and then selecting the target node set from the proxy node and the external node that has accessed the blockchain system.
In the first embodiment, when the blockchain system needs to be updated or rebuilt, after the seed node server obtains the node information of the proxy node in the blockchain system and the node information of the external node that has accessed the blockchain system, the seed node server may also query and store the information of other nodes connected to the proxy node and the external node that has accessed the blockchain system, so that the connection relationship between the nodes in the blockchain system may be determined according to the stored information, and the architecture of the blockchain system may be determined.
Specifically, in order to avoid the malicious external node from attacking the seed node server, when the seed node server queries and stores the information of the agent node and other nodes connected to the external node accessed to the block chain system, the seed node server may first query and store the information of the other nodes connected to the agent node; and then inquiring and storing the information of other nodes connected with the external node accessed into the block chain system through the temporarily bound udp port and the DHT algorithm, and closing the udp port after the inquiry is completed, so that the time interval of sending the information to the seed node server by the external node is reduced, and the difficulty of attacking the seed node server by the external node is increased.
Referring to fig. 3, fig. 3 is a schematic flow chart of a second embodiment of the present application.
In a second embodiment, the method is applied to a first external node which does not access a blockchain system, and may include:
step S201: sending an access request to a seed node server in a block chain system; the access request is used for requesting to access the block chain system;
step S202: receiving information of a target node set sent by a seed node server in a block chain system;
step S203: accessing information based on a target node set into a block chain system through a DHT algorithm; the target node set is a node set selected by the seed node server from the proxy node in the blockchain and the external node accessed to the blockchain system.
In the second embodiment, after accessing the blockchain system based on the information of the target node set through the DHT algorithm, the first external node may further determine whether the first external node itself accesses the blockchain system, and if not, delete the target node set received by the first external node itself, and send the node request information to the seed node server, so as to obtain information of a new target node set through the seed node server. Specifically, after determining that the first external node does not access the blockchain system, the first external node may actively disconnect the first external node from other nodes except the seed node server.
In the second embodiment, in order to quickly determine whether the first external node accesses the blockchain system, when determining whether the first external node accesses the blockchain system, the first external node may determine whether the first external node accesses the blockchain system by using the block height, and specifically, may determine whether the first block height of the first external node is unchanged; if the first block height is not changed, acquiring the latest block height on the seed node server; and judging whether the difference value between the first block height and the latest block height is greater than a preset value, if so, judging that the block chain system is not accessed.
