Include more or fewer components than shown in the figures, or combine certain components, or have a different arrangement of components.

As shown in Figure 2, in one embodiment, a method for managing blockchain nodes is proposed, which may include the following steps:

Step 201 , traverse all nodes in the current blockchain network to obtain time information of state changes of each node.

In this embodiment, the current blockchain network may include, but is not limited to, a consortium chain, a public chain, a private chain, and the like. The state of a node may include, but is not limited to, joining state, transaction state, pending invalidation state, and so on. All nodes in the current blockchain network are traversed according to a predetermined time interval to obtain the time information of the state change of each node. The predetermined time interval may be, for example, one day (24h), that is, each node is traversed once at a fixed time point every day. The state change time information of the node, such as the time when the node joined the blockchain network.

Step 202: Based on the time information of the state change of each node, obtain the time length of each node joining the current blockchain network.

In this embodiment, the time information (or node generation time) when each node joins the current blockchain network is extracted from the time information of the state change of each node, and the time when each node joins the current blockchain network is the same as the time when each node joins the current blockchain network. The current system time of the management node in the blockchain network is compared (for example, differential processing or time distance calculation processing can be performed) to determine the length of time for all nodes in the current dynamic blockchain network to join the current blockchain network (all nodes The duration of the generation), so that the blockchain network joining time attribute of all nodes can be obtained, which is used to indicate the relationship between the node and the current blockchain network.

Step 203: Based on the duration of each node joining the current blockchain network, select a node whose duration of joining the current blockchain network meets a preset condition as a target node, and assign a first authority to the target node.

In this embodiment, selecting a node whose duration of joining the current blockchain network satisfies a preset condition as a target node refers to selecting multiple newly added nodes (that is, nodes with a shorter duration of joining the current blockchain network) as the target node. The object to focus on (target node). The first permission here can be a limited permission. For example, the first permission is the observer permission. Generally, the observer permission only has the permission to read the ledger, part of the block transportation and basic data storage permission, but no more advanced permission. The scope of permission is compared. narrow.

Step 204: Obtain the historical behavior records of each target node in the current blockchain network, and determine the contribution value of the target node in the current blockchain network based on the historical behavior records.

In this embodiment, the historical behavior record of the target node in the current blockchain network may include, but is not limited to, how much load it has undertaken, how much data has been transmitted, how much storage capacity has been provided, and so on. The method of determining the contribution value of the target node in the current blockchain network may include, but is not limited to, transmitting X blocks X/10 points for other nodes, and executing Y transaction queries (to share how much the blockchain network shares). The query workload on the network) Y/8 points, providing Z standard storage blocks for storing data such as shared ledgers on the blockchain network Z points, and then calculating the total score of all behavior records of the target node, the total score Corresponding to the contribution value of the target node in the current blockchain network, for example, the higher the total score of all behavior records of the target node, the greater the contribution value of the target node in the current blockchain network.

In some embodiments, determining the contribution value of the target node in the current blockchain network based on the historical behavior record may include: assigning a positive or negative score to each historical behavior of each target node, accumulating all the history of each node The scoring result of the behavior obtains the scoring result of the target node, and the contribution value of the target node in the current blockchain network is determined according to the scoring result of the target node.

It can be understood that each target node has multiple historical behaviors, and each historical behavior is scored separately, and the final score of each node is the sum of the scores of all historical behavior records. Among them, the negative score may include the target node's illegal transaction once -1, the target node's refusal to store the corresponding data once -2, the target node providing service timeout -1 and so on.

Further, in some embodiments, a step S7 is also included, and this step is used for eliminating the target node when the cumulative scoring result of the target node is lower than the minimum threshold. For example, the target node has fewer positive scores and more negative scores. When the final score is less than or equal to 0, the node is removed from the dynamic blockchain network. Of course, this embodiment can also increase the minimum threshold, such as 5 points, etc., and the nodes below the minimum threshold will be eliminated. This method helps to urge each node member to actively participate in the operation of the blockchain network, and warns against misoperation Otherwise, the current blockchain network will be eliminated in the case of inaction, less action or wrong action, so that the managed blockchain network will have stronger vitality and vitality.

Step 205: Based on the contribution value of each target node in the current blockchain network, update the first authority of the target node to a second authority, wherein the authority level of the second authority is higher than the authority level of the first authority.

It can be understood that the scoring result of each target node is related to the historical behavior of the target node, and the historical behavior of the node can reflect the contribution value of the node to the current blockchain network, so based on the scoring results of each target node, The first authority of the target node is updated to the second authority, that is, the corresponding authority of the target node is based on the contribution value of the target node to the current blockchain.

It can be seen that this application selects a plurality of newly added nodes as target nodes according to the time when the nodes join the current blockchain network, and is the object of key observation, and only allocates lower authority (limited authority) to these newly joined target nodes. Then, according to the contribution value of these target nodes in the blockchain network, the authority of the target node with high contribution value is gradually increased, that is, the effective management and assistance of the blockchain network is realized based on the contribution value of the nodes in the current blockchain network. , by scoring the performance of the target node as the basis for the redistribution of authority, the fine-grained management strategy of nodes in the blockchain network is realized.

In some modified implementations of the embodiments of the present application, in order to prevent the access to the node from affecting the normal operation of the node, in step 201, all nodes in the current blockchain network are traversed, which may specifically include:

Step 2011: Based on the running information of all nodes in the current blockchain network, set the priority of traversing nodes.

The operation information of the node may include, but is not limited to, whether the node is running, the load rate at runtime, and the like.

Step 2012: Access all nodes in the current blockchain network according to priority.

It can be understood that the priority setting rule can be: count the operation information of each node in each time period (including whether it is running, load rate at runtime, etc.) Set the priority, such as 1 point-2 points, A\C\E\G\B, 2 points-3 points C/G/B/E/A, ... and so on. When preparing to traverse, read the current time, determine the time period in which the current time is located, and then traverse in the order of nodes in the priority based on the priority of the current time period that has been obtained, so that the application can first access relatively idle nodes , the later access to the busy node, it is possible that the original busy node is relatively idle during the later access, so as to maximize the access and data acquisition of the node during the relative idle time of the node, so this embodiment can be based on this method as much as possible. It can avoid the influence of the node access process in the blockchain network on the normal operation of the node.

In some modified implementations of the embodiments of the present application, in order to discover nodes whose joining time information has been tampered with by the node itself, step 202 , based on the time information of the state changes of each node, obtain the time length of each node joining the current blockchain network, specifically Can include:

Step 2021 , based on the time information of the state change of each node, extract the time information of the node joining the current blockchain network.

The time information of the state change of the node includes at least the time information of the state change of the node joining the blockchain network, so the time information of the node joining the current blockchain network can be extracted according to the time information of the state change of the node.

Step 2022: Perform randomness verification on the joining time information of the nodes, and mark the nodes whose joining time information has been tampered with dishonesty.

It can be understood that the randomness verification process may include, but is not limited to, collecting historical data on the chain of nodes adjacent to the node to be verified, and based on the node consensus technology, according to most or all of the nodes adjacent to the node to be verified. The chain history data determines whether the node joining time information has been tampered with, which may specifically include: parsing the chain history data of the node adjacent to the node to be verified, and obtaining the join of the current node recorded by the adjacent node according to the analysis result of the chain history data. Time consensus information, if most of the joining time consensus information (for example, 95%) is the same as the node joining time, it proves that the node joining time is accurate; otherwise, it is determined that the node information has been tampered with. If it is found that the joining time information of a node has been tampered with by the node itself, the node will be marked.

Step 2023: Compare the joining time information of each node with the current system time of the management node in the current blockchain network, and determine the duration of the node joining the current blockchain network.

Further, in some embodiments, in step 204, after scoring each target node, the scoring result of the node marked as dishonest in step 2022 is modified to zero to represent a punishment for dishonest nodes, In other implementations, it may also include: directly removing the dishonest node from the dynamic blockchain network, and restricting the node from being unable to join the current blockchain network for a period of time.

In some modified implementations of the embodiments of the present application, step 203, selecting a node whose duration of joining the current blockchain network satisfies a preset condition as a target node may include:

Step 2031: Sort all nodes in the current blockchain network based on the duration of each node joining the current blockchain network.

In this embodiment, all nodes in the current blockchain network can be sorted based on the attribute of the time of joining the blockchain network. For example, the first sorting result of all nodes can be formed according to the joining time from long to short. Or form the second sorting result of all nodes according to the joining time from short to long, so as to facilitate the screening of the nodes to be processed.

Step 2032: Select a preset number of nodes ranked at the beginning or end of the sorting result as the target node, or select a node in the sorting result whose duration of joining the current blockchain network is not greater than the preset time threshold as the target node. Wherein, the time for any target node to join the current blockchain network is less than the time for other nodes in the current blockchain network except the target node to join the current blockchain network.

In this embodiment, selecting a preset number of nodes at the beginning or end of the sorting result as the target node may be to filter out a plurality of nodes with a shorter joining time from the first sorting result or the second sorting result For example, several nodes in the back can be screened out from the first sorting result or several nodes in the front can be screened out from the second sorting result. Focus on long nodes.

Select the node whose duration of joining the current blockchain network is not greater than the preset time threshold in the sorting result as the target node. It can be the node whose joining time is less than or equal to the threshold from the first sorting result or the second sorting result, that is, from the first sorting result or the second sorting result. After a node is found in the sorting result that is less than the threshold, the nodes behind the node in the first sorting result will be filtered out or the nodes in front of the node in the second sorting result will be filtered out. This method helps to improve The computing efficiency helps to realize the technical solution provided by this application more quickly when the blockchain network is complex and there is a lot of data.

Further, in some embodiments, step 2031 may further include sequentially numbering each node from small to large in the order of time from short to long, for example, starting from 1, 2, 3 . Several nodes can be directly and quickly cut out according to the number, for example, 10 nodes (numbered 1-10) not greater than 10 can be directly screened out. In this embodiment, multiple nodes with a short joining time can be implemented in this way. The fast and efficient determination of the algorithm has the outstanding advantages of simple algorithm implementation, small resource occupation, and very fast execution speed.

Further, as shown in FIG. 3 , in order to enable the nodes in the blockchain network to upgrade their own authority fairly, in some modified implementations of the embodiments of this application, the management method of the blockchain nodes further includes:

Step 206: Receive a scoring request from other nodes other than the target node in the current blockchain network.

In this embodiment, the nodes that are not screened in step 203 can send a scoring request. After receiving the scoring request in step 204, the corresponding node that sent the scoring request can be included in the target node set, and the node that sent the scoring request can be included in the target node set. As a target node, a score is determined in step 204 together with other filtered target nodes, and then the requesting target node is assigned permissions according to the score.

Step 207: Use the node that issued the scoring request as the target node, and mark the node for scoring.

Step 208 : Determine the candidate management node of the current blockchain network based on the number of times the target node is scored and marked and/or the authority change of the target node.

In this embodiment, in step 207, the node that sends out the scoring request is recorded and given an identifier A to it, and the authority changes of the nodes given the identifier A are monitored. If the set value is set, for example, it can be 8 times, then these nodes are used as elements in the candidate set of management nodes of the blockchain node. When it is necessary to determine the node for managing the whole or part of the blockchain network as the administrator, A suitable node may be selected as a management node from the candidate set of management nodes.

The above methods help to improve the enthusiasm of nodes in the blockchain network, and can promote each node to actively participate in transactions and undertake corresponding tasks, so as to improve their own contribution. , so this application can also provide a solution for nodes in the blockchain to fairly upgrade their own authority.

Further, in some modified implementations of the embodiments of the present application, step 205 further includes a step of inspecting the behavior of each target node within a period of time after the current scoring, and then performing a second step on each target node according to the inspection result. Score to give each target node new permissions, and then return to step 1. Wherein, in some embodiments, during this period of time, for example, it may be one month or two months, etc., the investigated items may include but are not limited to how much load is borne, how much data is transmitted, how much storage capacity is provided, etc., Each target node is directly scored based on the contribution made by the target node to the entire blockchain network within this time period, that is, the contribution degree, and in some embodiments, the contribution degree value can be directly used as the score value.

As shown in FIG. 4 , in one embodiment, a management device for blockchain nodes is provided, which can effectively manage and assist the blockchain network based on the contribution value of the nodes in the blockchain network. The device specifically Can include:
