Detailed Description

The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all 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 application.

First, the block chains, blocks and consensus network mentioned in the embodiments of the present application will be described.

1. Block chains: in a narrow sense, a block chain is a chain data structure taking a block as a basic unit, and the prior transaction history is verified by utilizing a digital abstract in the block, so that the block chain is suitable for the requirements of tamper resistance and expandability under a distributed accounting scene; in a broad sense, blockchain also refers to distributed accounting techniques implemented by blockchain architecture, including distributed consensus, privacy and security protection, peer-to-peer communication techniques, network protocols, intelligent contracts, and the like. The goal of the blockchain is to implement a distributed data record ledger that allows only additions and not deletions. The basic structure of the ledger bottom layer is a linear linked list. The linked list is composed of a series of 'blocks', the Hash (Hash) value of the previous block is recorded in the subsequent block, and whether each block (and the transaction in the block) is legal or not can be quickly checked by calculating the Hash value. If a node in the network proposes to add a new block, the block must be acknowledged via a consensus mechanism.

2. Block (Block): all transactions and status results, etc. occurring over a period of time are recorded, which is a consensus on the current ledger status. Specifically, for a block chain, each time data is written, i.e. the above transaction process, a block is created.

3. A consensus network: the network consists of network nodes with consensus authority, at least three consensus nodes exist in the consensus network, the at least three consensus nodes can perform consensus on the received transaction blocks, and the transaction blocks can be uploaded to a block chain after passing through the consensus network. In this application, the consensus node refers to a network node whose node attribute is a consensus attribute.

Specifically, reference may be made to fig. 1a, where fig. 1a is a schematic diagram of a consensus network provided in an embodiment of the present application. As shown in fig. 1a, the consensus network 100 is a system for performing data sharing between nodes, the consensus network 100 may include a plurality of nodes 101, the plurality of nodes 101 may be clients in the consensus network 100, and each node 101 is a network node having a consensus right to perform consensus on a block. Each node 101 may receive input information and maintain shared data within the consensus network 100 based on the received input information while operating normally. In order to ensure information intercommunication in the consensus network 100, an information connection may exist between each node 101 in the consensus network 100, and information transmission may be performed between the nodes 101 through the information connection. For example, when an arbitrary node 101 in the consensus network 100 receives input information, other nodes 101 in the consensus network 100 acquire the input information according to a consensus algorithm, and store the input information as data in shared data, so that the data stored on all nodes in the consensus network 100 are consistent. Each node 101 may perform consensus on the transaction blocks formed by the input information, and if the consensus of the transaction blocks passes, each node 101 may add the transaction blocks passing the consensus to the block chain stored by itself to store the input information, so as to achieve consistency of data stored on all nodes in the consensus network 100.

Each node 101 in the consensus network 100 has a corresponding node identifier, and each node 101 in the consensus network 100 may store the node identifiers of other nodes in the consensus network 100, so that the generated block is broadcast to other nodes in the consensus network 100 according to the node identifiers of other nodes. Each node 101 may maintain a node identifier list as shown in the following table, and store the node name and the node identifier in the node identifier list correspondingly. The node identifier may be an Internet Protocol (IP) address and any other information that can be used to identify the node, such as a character string that can be used as a unique identifier, and only the character string that is used as the unique identifier is described in table 1. As shown in table 1 below:

node name	Node identification
		Node 1	A154267
Node 2	A154468
		…	…
Node N	A154254

Each node 101 in the consensus network 100 may broadcast the obtained transaction block to other nodes through the maintained node identification list, so that all nodes 101 in the consensus network 100 can agree on the transaction block, and if the agreement passes, each node 101 adds the transaction block to a stored block chain.

Referring to fig. 1b, fig. 1b is a block link node management architecture diagram provided in an embodiment of the present application, as shown in fig. 1b, when a network node is added to a consensus network, a consensus network addition request is sent, and after a computer device obtains the consensus network addition request sent by the network node, the computer device manages the network node, where the network node may be one network node, or may be at least two network nodes, such as a network node 102 and a network node 103. Specifically, taking the network node 102 as an example, the network node 102 is used as a target network node, when the target network node joins in a consensus network, a consensus network addition request is sent, when a computer device obtains the consensus network addition request, an intelligent contract is triggered, a node attribute of the target network node is determined as a candidate attribute based on the intelligent contract, and target node identity information of the target network node is added to consensus configuration information stored in the intelligent contract. And when the consensus validation time of the target network node is reached, triggering an intelligent contract, and switching the node attribute of the target network node into the consensus attribute based on the intelligent contract so as to add the target network node into the consensus network. Optionally, when consensus network addition requests of multiple network nodes are obtained, for example, when consensus network addition requests of the

network nodes

102 and 103 are obtained, each network node may be selected based on node identity information of each network node, one or at least two network nodes are obtained from the multiple network nodes as new consensus nodes to be added into the consensus network, and node attributes of the network nodes serving as the new consensus nodes are switched to the consensus attributes. According to the method and the device, the network nodes in the consensus network are managed through the process, under the condition that the consensus network is not required to be redeployed, the consensus nodes in the consensus network are added or deleted on the basis of the intelligent contract, namely, the management of each network node in the consensus network is realized, the system bottom layer framework of the block chain is not required to be adjusted, the time and the resources consumed by updating the consensus configuration information in the block chain when the consensus network is changed are reduced, the management efficiency of the consensus network is improved, and the cost is reduced.

It is understood that the method provided by the embodiment of the present application may be executed by a computer device, which includes but is not limited to a terminal device or a server. In the embodiment of the present application, an execution subject for performing the management of the blockchain node may be a computer device. The computer device may be a server or a terminal device, or a system composed of a server and a terminal device, where the above-mentioned terminal device may be an electronic device, including but not limited to a mobile phone, a tablet computer, a desktop computer, a notebook computer, a palmtop computer, a Mobile Internet Device (MID), a wearable device (e.g., a smart watch, a smart band, etc.), and the like. Optionally, the embodiment of the present application may also be executed through an intelligent contract in the block chain, specifically, when a target network node sends a consensus network addition request, the intelligent contract monitors the consensus network addition request, acquires target node identity information of the target network node according to the consensus network addition request, and switches a node attribute of the target network node based on the target node identity information, so as to add the target network node to the consensus network.

Further, please refer to fig. 2, wherein fig. 2 is a schematic view of a block link point management scenario provided in an embodiment of the present application. As shown in fig. 2, when a target network node 201 needs to join a consensus network 202, a consensus network addition request 203 is sent, a computer device 204 obtains the consensus network addition request 203 of the target network node, the computer device 204 obtains target node identity information of the target network node 201 through the consensus network addition request 203, the target node identity information includes a node attribute 205 of the target network node 201 and a consensus validation time 206, the computer device 204 determines the node attribute 205 of the target network node 201 as a candidate attribute based on an intelligent contract, generates target node identity information according to the node attribute 205 of the target network node 201, and adds the target node identity information of the target network node 201 to consensus configuration information to indicate that the target network node 201 is a node that is about to join the consensus network or has already joined the consensus network. When the computer device 204 determines that the consensus validation time 206 is reached based on the intelligent contract, the intelligent contract is triggered, the node attribute 205 of the target network node 201 is switched from the candidate attribute to the consensus attribute based on the intelligent contract, and the computer device 204 updates the target node identity information in the consensus configuration information according to the switched node attribute of the target network node 201, so that the target network node 201 is added to the consensus network, and the target network node 201 has the consensus right. Optionally, when the node information of the target network node 201 is only stored in the consensus configuration information, the computer device 204 switches the node attribute of the target node identity information in the consensus configuration information to the consensus attribute when the consensus validation time is reached, so as to add the target network node 201 to the consensus network.

Further, please refer to fig. 3, wherein fig. 3 is a flowchart of a block link point management method according to an embodiment of the present disclosure. As shown in fig. 3, the above-mentioned computer device is used as an execution subject to describe, and the block link point management process includes the following steps:

step S301, acquiring a consensus network adding request of a target network node, triggering an intelligent contract based on the consensus network adding request, determining a node attribute of the target network node as a candidate attribute based on the intelligent contract, and generating target node identity information of the target network node according to the node attribute of the target network node and the consensus validation time.

Specifically, the computer device obtains a consensus network addition request of a target network node, triggers an intelligent contract based on the consensus network addition request, determines a node attribute of the target network node as a candidate attribute (which is equivalent to marking the target network node as a candidate network node) based on the intelligent contract to indicate that the target network node is a node to be added to the consensus network, and generates target node identity information of the target network node according to the node attribute of the target network node and the consensus validation time. Optionally, the consensus network addition request further includes a target node weight of the target network node, where the target node weight may be a virtual asset of the target network node, or may be weight data that the target network node may use for mortgage, and the like, which is not limited herein. When the computer equipment acquires the consensus network adding request, determining the node attribute of the target network node as a candidate attribute based on an intelligent contract, and distributing consensus effective time for the target network node, wherein the consensus effective time is used for indicating the time that the target network node can be used as a consensus node to perform consensus on the transaction blocks. The node attribute, the consensus validation time and the like of the target network node are used as the target node identity information of the target network node, wherein the target node identity information may further include a target node identifier or a target node weight and the like.

Step S302, the target node identity information of the target network node is added to the consensus configuration information stored in the intelligent contract.

Specifically, the consensus configuration information includes node identity information of each consensus node, a minimum consensus node number, a node weight of each consensus node, and the like, where the consensus node is a network node whose node attribute is a consensus attribute, and optionally, the consensus configuration information further includes node identity information of a candidate network node, where the candidate network node is a network node whose node attribute is a candidate attribute, and the candidate network node is used to indicate a network node about to join the consensus network. The node identity information includes a node identifier, a node attribute, a node weight, a consensus validation time and the like of a corresponding consensus node. The consensus validation time of the consensus node may be a fixed consensus value, and the fixed consensus value is used to indicate that the corresponding consensus node has the consensus right. Specifically, the target node identity information of the target network node is added to the consensus configuration information stored in the intelligent contract, and represents the consensus validation time when the target network node is reached, so that the target network node has the consensus right and can perform consensus on the received transaction blocks. The consensus configuration information may be stored in a blockchain network in a format such as a graph, and is used to maintain a consensus network in the blockchain network and manage all consensus nodes in the consensus network. For example, assuming that the consensus arrangement information is stored in a table format in a blockchain network, the consensus arrangement information can be as shown in table 2 below:

table 2 stores node identity information of each consensus node in the current consensus network and node identity information of a candidate network node, where the consensus node is a network node whose node attribute is a consensus attribute, and the candidate network node is a network node whose node attribute is a candidate attribute in the consensus configuration information. As can be seen from table 2, the consensus network includes network nodes with node identifiers a154267, a154468 and a154254, etc., where the node weight of the network node with node identifier a154267 is 20, the node weight of the network node with node identifier a154468 is 25, the node weight of the network node with node identifier a154254 is 30, and so on. The computer device obtains a target node identifier of a target network node as a152648, sets the node attribute of the target network node as a candidate attribute, sets the node attribute of the target node identifier a152648 in the consensus configuration information as a candidate attribute, and writes the target node weight 20 of the target network node into the consensus configuration information.

And step S303, when the consensus validation time is reached, triggering an intelligent contract, acquiring target node identity information in the consensus configuration information based on the intelligent contract, switching the node attribute in the target node identity information into the consensus attribute to obtain updated consensus configuration information, and adding the target network node to the consensus network according to the updated consensus configuration information.

Specifically, when the consensus is valid, the target node identity information of the target network node still exists in the consensus configuration information, or the target network node has a network access right, which indicates that no abnormal behavior occurs in the target network node before the target network node is used as the consensus node, so that the node attribute of the target network node is switched to the consensus attribute, the target node identity information in the consensus configuration information in table 2 is updated according to the switched node attribute (that is, the node attribute of the target node identity information is updated to the consensus attribute in the consensus configuration information), the updated consensus configuration information is obtained, and the target network node is added to the consensus network according to the updated consensus configuration information. Optionally, if the target network node does not carry the node attribute, but only stores the node attribute of the target network node in the consensus configuration information, when the consensus validation time is reached, the node attribute of the target node identity information in the consensus configuration information is updated to be the consensus attribute, so that the target network node is added to the consensus network according to the updated consensus configuration information.

According to the embodiment of the application, through the block chain node management process, the computer equipment acquires the consensus network adding request of the target network node, triggers an intelligent contract based on the consensus network adding request, determines the node attribute of the target network node as a candidate attribute based on the intelligent contract, generates the target node identity information of the target network node according to the node attribute of the target network node and the consensus effective time, and adds the target node identity information of the target network node to the consensus configuration information stored in the intelligent contract; when the consensus validation time is reached, triggering an intelligent contract, acquiring target node identity information in the consensus configuration information based on the intelligent contract, switching the node attribute in the target node identity information into the consensus attribute to obtain updated consensus configuration information, and adding the target network node into the consensus network according to the updated consensus configuration information. According to the method and the device, each network node in the consensus network is managed through the intelligent contract, the consensus network is updated, the network nodes in the consensus network are added and deleted, the bottom data of the block chain does not need to be called, and therefore resource loss of block chain link point management is reduced, and management efficiency of the block chain nodes is improved.

Further, referring to fig. 4, fig. 4 is a schematic block link point management flowchart provided in an embodiment of the present application. As shown in fig. 4, the method comprises the following steps:

step S401, acquiring a consensus network adding request of a target network node, determining a node attribute of the target network node as a candidate attribute based on an intelligent contract, and generating target node identity information of the target network node.

Specifically, the computer device obtains a consensus network addition request of the target network node, triggers an intelligent contract based on the consensus network addition request, determines a node attribute of the target network node as a candidate attribute based on the intelligent contract, and generates target node identity information of the target network node according to the node attribute of the target network node and the consensus validation time, which may be specifically described in step S301 in fig. 3. Further, the target network node may be cached in a set of candidate network nodes, the set of candidate network nodes including at least three candidate network nodes including the target network node.

Specifically, referring to fig. 5, fig. 5 is a schematic diagram of a consensus node addition scenario provided in the embodiment of the present application. As shown in fig. 5, when a target network node 501 sends a consensus network addition request to join a consensus network 502, a computer device acquires the consensus network addition request, triggers an intelligent contract, determines a node attribute of the target network node 501 as a candidate attribute based on the intelligent contract, and adds the target network node 501 as a candidate network node to a candidate network node set 503.

And step S402, carrying out consensus on the target network nodes.

Specifically, the target network node is broadcasted to the consensus node for consensus, and the node attribute of the consensus node is a consensus attribute; if the consensus fails (the consensus fails), indicating that the target network node is abnormal, executing step S405 to delete the network access permission of the target network node, where the network access permission is a permission to join the blockchain network; if the consensus passes, step S403 is executed to add the target node identity information of the target network node to the consensus configuration information stored in the intelligent contract. Specifically, the target network node is identified by a consensus node in a consensus network, assuming that 4 consensus nodes (node a, node B, node C, and node D, respectively) exist in the consensus network, the used consensus algorithm is byzantine 2/3, and the target network node is node E, the computer device broadcasts the target network node to the 4 consensus nodes in the consensus network, and when any 3 consensus nodes or more than 3 consensus nodes exist in the node a, the node B, the node C, and the node D identify the target network node, the target network node is considered to be identified as passing, otherwise, the target network node is considered to be identified as not passing.

Step S403, adding the target node identity information of the target network node to the consensus configuration information.

Specifically, the computer device adds the target node identity information of the target network node to the consensus configuration information stored in the intelligent contract based on the intelligent contract, specifically referring to the specific description shown in step S302 in fig. 3. The target node identity information includes a target node identifier, a node attribute, and a consensus validation time, and optionally, the target node identity information may further include a target node weight, and the like. And when the target node identity information also comprises the target node weight of the target network node, acquiring the target node weight and transferring the target node weight to the consensus weight pool. The consensus weight pool comprises node weights of network nodes of which the node attributes are consensus attributes or candidate attributes, wherein the node weights are weights of mortgages when the corresponding network nodes join the consensus network. For example, if the node of node a is identified as a154267, the node of node B is identified as a154468, the node of node C is identified as a154254, the node of node D is identified as a154356, and the node of node E is identified as a152648, the consensus weight pool includes the node weight of node a, the node weight of node B, the node weight of node C, the node weight of node D, and the node weight of node E, 20.

Step S404, verifying the target network node, and detecting whether the verification passes.

Specifically, when consensus data of a target network node is received, a node attribute of the target network node is obtained; and when the node attribute is the candidate attribute, executing the step S405, and deleting the network access authority of the target network node, wherein the network access authority is the authority for joining the block chain network. When the consensus data of the target network node is received, the target network node is indicated to perform consensus on the transaction block, the computer device triggers an intelligent contract to obtain the node attribute of the target network node, and when the node attribute is a candidate attribute, the target network node is determined not to have consensus authority, so that the computer device determines that the target network node has abnormal behavior, and step S405 is executed to delete the network access authority of the target network node.

When the target node weight of the target network node is detected, when the target node weight is transferred to the consensus weight pool, transfer failure may occur, or the target node weight is abnormal (for example, the target node weight is null, etc.), or abnormal situations such as the target node weight submitted by the target network node is not obtained, and the like may occur. Therefore, when the consensus data of the target network node for the transaction block is received, acquiring a consensus weight pool from the intelligent contract; the consensus weight pool comprises node weights of the network nodes in the block chain, and the node weights are used for representing certificates for consensus of the corresponding network nodes; searching a target node weight of a target network node in a consensus weight pool based on an intelligent contract; if the consensus weight pool comprises the target node weight, indicating that the target network node has weight mortgage, and adding the consensus data of the target network node aiming at the transaction block into the consensus information set aiming at the transaction block; if the consensus weight pool does not include the target node weight, step S405 is executed to delete the network access permission of the target network node.

Further, if the consensus weight pool comprises a target node weight, when consensus data of the target network node for the transaction block is received, acquiring a node attribute of the target network node based on an intelligent contract; when the node attribute of the target network node is a candidate attribute, determining the abnormal behavior weight of the target network node; the weight of the target node after the weight of the abnormal behavior is removed is taken as a legal weight, and the legal weight is transferred to the target network node; and when the node attribute of the target network node is the consensus attribute, adding the consensus data of the target network node aiming at the transaction block into the consensus information set aiming at the transaction block. For example, when the node weight of the node E is 20, the node E generates consensus data for the transaction block, and when the computer device acquires the consensus data of the node E for the transaction block, the node attribute of the node E is acquired as a candidate attribute, the abnormal behavior weight of the node E is determined to be 5, the abnormal behavior weight 5 is removed from the target node weight 20, the legal weight 15 is obtained, and the legal weight 15 is transferred to the node E. The abnormal behavior weight is determined based on the number of times of the abnormal behavior of the target network node or the abnormal degree, and the larger the number of times of the abnormal behavior of the target network node is or the larger the abnormal degree is, the larger the abnormal behavior weight is. If the consensus data of the target network node is not received and the identity information of the target node includes the target node weight, the consensus weight pool includes the target node weight, and it is determined that the target network node is verified, and step S406 is performed.

Specifically, referring to fig. 6, fig. 6 is a schematic view of a node weight processing scenario provided in the embodiment of the present application. As shown in fig. 6, the target network node 601 broadcasts the consensus data 602 for the transaction block to other network nodes in the consensus network 603, where the consensus data 602 includes the block height of the transaction block and the data of approving the transaction block, when the computer device receives the consensus data 602, the node attribute of the target network node 601 is obtained from the consensus configuration information 604, the node attribute of the target network node 601 is obtained as a candidate attribute, the target node weight 606 of the target network node 601 is obtained from the consensus weight pool 605, the abnormal behavior weight 607 of the target network node 601 is determined, the weight of the target node 606 after the abnormal behavior weight 607 is removed is taken as the legal weight 608, the legal weight 608 is transferred to the target network node 601, and the abnormal behavior weight 607 is added into the consensus weight pool 605.

And step S405, deleting the network access authority of the target network node.

Specifically, when the node attribute of the target network node is a candidate attribute, determining that the target network node is an abnormal node, accumulating the times that the target network node is the abnormal node as the abnormal times of the target network node, and acquiring the authority deletion duration of the target network node according to the abnormal times; and deleting the network access authority of the target network node within the authority deletion duration. When the consensus configuration information comprises the target node identity information of the target network node, deleting the target node identity information in the consensus configuration information.

Step S406, determining a consensus node to be worked from the candidate network node set, and determining consensus effective time of the target network node when the consensus node to be worked is the target network node.

Specifically, a candidate network node set with node attributes as candidate attributes in the consensus configuration information is obtained based on an intelligent contract, the candidate network node set comprises at least three candidate network nodes, and the at least three candidate network nodes comprise target network nodes; acquiring the candidate node weight of each candidate network node from the consensus weight pool; determining a node to be worked common knowledge from at least three candidate network nodes according to the candidate node weight; and if the node to be worked is the target network node, determining the consensus effective time of the target network node as the next block generation time. Optionally, the candidate network node set may also be generated when there is a network node sending a consensus network addition request. Specifically, referring to fig. 5, a to-be-operated consensus node is determined from at least three candidate network nodes in the candidate network node set 503, and if the to-be-operated consensus node is the target network node 501, the consensus effective time 504 of the target network node 501 is determined as the next block generation time. For example, if the maximum block height in the current consensus network is 100, and the node to be worked is determined to be the target network node 501, the consensus effective time of the target network node 501 is updated to the generation time of the block with the block height of 101.

The computer network obtains the node weight of each candidate network node in the consensus weight pool, and determines the consensus node to be worked in the at least three candidate network nodes according to the node weight of each candidate network node and a node selection algorithm. The node selection algorithm may be a maximum weight selection algorithm, or an algorithm for performing selection based on the node weight, the node identity information, and the like, which is not limited herein.

And step S407, when the consensus validation time of the target network node is reached, adding the target network node into the consensus network based on the intelligent contract.

Specifically, when the consensus becomes effective, an intelligent contract is triggered, target node identity information in the consensus configuration information is obtained based on the intelligent contract, the node attribute in the target node identity information is switched to the consensus attribute to obtain updated consensus configuration information, and the target network node is added to the consensus network according to the updated consensus configuration information, which is specifically described in step S303 in fig. 3. Specifically, referring to fig. 5, the intelligent contract includes a timer, and when the timer reaches the consensus validation time 504, the node attribute of the target network node 501 is switched to the consensus attribute based on the intelligent contract, and the target network node 501 is added to the consensus network 505. Optionally, the target node identifier of the target network node may be broadcast to other consensus nodes in the consensus network, the other consensus nodes add the target node identifier of the target network node to the node identifier list maintained by the other consensus nodes to obtain an updated node identifier list, and the target network node stores the updated node identifier list, so that all the consensus nodes (including the target network node) in the current consensus network store the updated node identifier list. In the method for adding the target network node to the consensus network, other methods that can establish a network connection between the target network node and other consensus nodes may also be used, which is not limited herein.

Further, acquiring the minimum consensus passing node number in the consensus configuration information based on the intelligent contract, and determining the total number of consensus nodes according to a node identity information set in the consensus configuration information, wherein the node identity information set comprises target node identity information; the minimum consensus passing node number is the minimum consensus node number required by the block passing consensus in the consensus configuration information; updating the minimum consensus passing node number in the consensus configuration information according to the consensus algorithm and the total number of the consensus nodes, and switching the node attribute of the target network node in the consensus configuration information into the consensus attribute to obtain updated consensus configuration information; and adding the target network node to the consensus network according to the updated consensus configuration information.

For example, referring to fig. 7, fig. 7 is a schematic view of a scenario for updating consensus configuration information provided in an embodiment of the present application. As shown in fig. 7, before the target network node 702 is added to the consensus network 701, the consensus network 701 includes 4 consensus nodes, and assuming that the consensus algorithm is byzantine 2/3, the minimum consensus passing node number 704a in the obtained consensus configuration information 703a is 3, and the node attribute 705a of the target network node 702 in the consensus configuration information 703a is a candidate attribute. Acquiring a node identity information set in the consensus configuration information 703a, taking the number of node identity information included in the node identity information set as the total number of consensus nodes, to obtain that the total number of the consensus nodes is 5 (4 consensus nodes and a target network node which has just become a consensus node), updating the minimum consensus passing node number 704a in the consensus configuration information 703a according to a consensus algorithm byzantine 2/3 and the total number of the consensus nodes 5, that is, updating the minimum consensus passing node number from 3 to 4, to obtain an updated minimum consensus passing node number 704b. And the node attribute 705a of the target network node 702 in the consensus configuration information 703a is switched to the consensus attribute to obtain an updated node attribute 705b, so as to obtain updated consensus configuration information 703b, and the target network node 702 is added to the consensus network 701 according to the updated consensus configuration information 703 b.

Step S408, when the consensus network quit request of the target network node is received, the target node identity information in the consensus configuration information is deleted based on the intelligent contract, and the target network node is deleted from the consensus network.

Specifically, when a consensus network quit request of a target network node is received, an intelligent contract is triggered based on the consensus network quit request, and a consensus weight pool is obtained from the intelligent contract; acquiring a target node weight from the consensus weight pool based on an intelligent contract; the target node weight comprises a node sub weight and a network node to which the weight corresponding to the node sub weight belongs; the network node to which the weight belongs comprises a target network node; and transferring the node sub-weight to the network node to which the corresponding weight belongs. For example, when the node E joins the consensus network, the node E1 provides the node E with the node sub-weight 5, and the node E2 provides the node E with the node sub-weight 2, wherein the node E (target network node) can only use the node sub-weight as a basis for selecting but does not have a use weight of the node sub-weight, for example, the node E can use the node sub-weight 5 provided by the node E1 as a basis for selecting the consensus node, and cannot use the node sub-weight 5. When computer equipment receives a consensus network exit request of a node E, target node weight 20 is obtained from a consensus weight pool based on an intelligent contract, the target node weight 20 comprises node sub-weight 13 of the node E, node sub-weight 5 of the node E1 and node sub-weight 2 of the node E2, the node sub-weight 13 is transferred to the node E, the node sub-weight 5 is transferred to the node E1, and the node sub-weight 2 is transferred to the node E2.

Optionally, between the step S407 and the step S408, step S404 may also be executed to verify the target network node, in which, when the consensus data of the target network node is received, the node of the target network node belongs to the consensus attribute, and when the target node identity information includes the target node weight, the consensus weight pool includes the target node weight, and it is determined that the target network node is verified.

The method comprises the steps of acquiring a consensus network adding request of a target network node, triggering an intelligent contract, determining a node attribute of the target network node as a candidate attribute based on the intelligent contract, and generating target node identity information of the target network node according to the node attribute of the target network node and consensus validation time; adding the target node identity information of the target network node to the consensus configuration information stored in the intelligent contract; when the consensus validation time is reached, triggering an intelligent contract, acquiring target node identity information in the consensus configuration information based on the intelligent contract, switching the node attribute in the target node identity information into the consensus attribute to obtain updated consensus configuration information, and adding the target network node to the consensus network according to the updated consensus configuration information. The nodes in the consensus network are managed through the intelligent contract, and the consensus configuration information can be updated, so that the nodes in the consensus network can be updated under the condition that the system bottom layer architecture of the block chain is not required to be adjusted, the efficiency can be improved, and the cost can be reduced when the consensus configuration information in the block chain is updated. Meanwhile, when the network node is added into the consensus network, the network node is not directly added into the consensus network, but the network node is verified firstly to determine the legality of the network node, so that the safety of the consensus network is improved.
