The implementation of the technical solution in the embodiments of the present application is described in detail below:

FIG. 3 schematically illustrates a flowchart of a method for managing a blockchain network according to an embodiment of the present application. The method for managing a blockchain network is performed by the electronic device described in the foregoing embodiment. Referring to FIG. 3, the method for managing a blockchain network includes at least steps S310 to S330, which are described in detail as follows:

In step S310, update information of public configuration parameters in the blockchain network is obtained.

In an embodiment of the present application, the blockchain network may be a public chain network, a private chain network, or an alliance chain network. The public configuration parameters may refer to the basic information required to generate the blockchain network, and may include the blockchain. The number of nodes, the size of a block, how often a block is generated, mining rewards, etc.

In step S320, transaction information of the blockchain network is generated according to the update information.

In an embodiment of the present application, since the transaction information includes a transaction type (that is, type) and a transaction content (that is, data), the transaction content may be generated according to the update information of the public configuration parameters, and the transaction type is configured to the public information. The type of configuration parameter modification, and then generate transaction information based on the transaction content and transaction type.

For example, for the update information of the number of nodes, transaction information with a transaction type of "change node" and transaction content with an updated node list can be generated.

In step S330, broadcasting the transaction information in the blockchain network, so that after the nodes in the blockchain network reach a consensus on the transaction information, the public configuration is performed according to the transaction information. Parameters are updated.

The technical solution of the embodiment shown in FIG. 3 makes it possible to broadcast update information of public configuration parameters as transaction information in a blockchain network, so that after nodes in the blockchain network reach a consensus on the transaction information, based on the update The information updates the public configuration parameters, achieving the purpose of updating the public configuration parameters during the operation of the blockchain node, and improving the update efficiency of the public configuration parameters.

Based on the technical solution of the embodiment shown in FIG. 3, in an embodiment of the present application, the update timing of the common configuration parameters may also be broadcast in a blockchain network, so that the nodes in the blockchain network are at Updating the common configuration parameter at a time point corresponding to the update timing. The technical solution of this embodiment enables each blockchain node to update the common configuration parameters at the same time point, and avoids the confusion caused by the adoption of different public configuration parameters by different blockchain nodes due to different update timing of the common configuration parameters. The problem. For example, some blockchain nodes update the public configuration parameters first, while other blockchain nodes delay updating for a period of time, then during this period, because the blockchain nodes use different public configuration parameters, then Its consensus strategy will also make a difference, which will affect the normal operation of the blockchain network.

In an embodiment of the present application, the above-mentioned update timing of the common configuration parameters may be added to the above-mentioned transaction information (that is, the transaction information generated by the common configuration parameters) to broadcast the update timing by broadcasting the transaction information. For example, you can add the update timing to the transaction content.

In an embodiment of the present application, the above-mentioned update timing of the public configuration parameters may include a specified block height, that is, the specified block height is broadcast in the blockchain network as the update timing of the public configuration parameters. Among them, the block height is the identifier of the block. Since the block has a certain generation time, after the generated block reaches the specified block height, it can be determined that the update timing of the public configuration parameters is reached.

In an embodiment of the present application, a predetermined number of blocks differ between the height of the specified block and the height of the block where the above-mentioned transaction information (that is, the transaction information generated by the common configuration parameter) is located, that is, in the place where the transaction information is located. The public configuration parameters are updated when a predetermined number of blocks are generated after the block.

In one embodiment of the present application, the above-mentioned predetermined number is positively related to the network delay of the blockchain network. For example, if the network delay is large, the predetermined number can be set to a large value to ensure that all or most of the blockchain nodes can receive transaction information (that is, transaction information generated by public configuration parameters) and perform Verification confirmation. If the network delay is small, the predetermined number can be set to a smaller value to update the common configuration parameters as soon as possible.

In a specific application scenario of the present application, the aforementioned blockchain network may be a blockchain network using a voting-based consensus mechanism, such as an alliance chain network. Because the voting-based consensus mechanism needs to confirm the number of nodes in the network to determine that most of the nodes can reach a consensus on the transaction information (usually 32 + 1 nodes vote to confirm that they have reached a consensus). In the current solution, if the number of nodes needs to be changed, all nodes need to be restarted to reconfirm the number of nodes. In the technical solution of the embodiment of the present application, nodes in the blockchain network can be added and / or deleted The information is broadcast in the blockchain network as transaction information, so that after the nodes in the blockchain network reach a consensus on the transaction information, the information of the blockchain node is updated based on the update information, and the The purpose of updating the node information during the operation of the chain node solves the problem that the node information cannot be modified during the operation of the blockchain node, and improves the efficiency of updating the node information.

The technical solution of the above embodiment is described from the node side that broadcasts the transaction information, and the technical solution of the embodiment of the present application is further explained from the node side that receives the transaction information.

FIG. 4 schematically illustrates a flowchart of a method for managing a blockchain network according to an embodiment of the present application. Referring to FIG. 4, the method specifically includes the following steps:

Step S410: Obtain transaction information broadcasted on the blockchain network.

In one embodiment of the present application, a block broadcast in a blockchain network can be obtained, and then the transaction information is obtained from the block.

In step S420, it is determined whether the transaction information includes update information of public configuration parameters in the blockchain network.

In an embodiment of the present application, a node that broadcasts transaction information may generate transaction information according to the update information of the public configuration parameters of the blockchain network, so the node that receives the transaction information may determine whether the transaction information includes the public configuration parameters. Update information.

Step S430, if the transaction information includes update information of the public configuration parameters, after the nodes in the blockchain network reach a consensus on the transaction information, the public configuration parameters are updated according to the update information. Update.

The technical solution of the embodiment shown in FIG. 4 enables the nodes in the blockchain network to reach consensus on the transaction information that includes the update information of the public configuration parameters, and then can update the public configuration parameters based on the update information, thereby realizing the presence in the district. The purpose of updating the common configuration parameters during the operation of the blockchain node improves the efficiency of updating the common configuration parameters.

Based on the technical solution of the embodiment shown in FIG. 4, in an embodiment of the present application, the update timing of the public configuration parameters can also be obtained, and then after the nodes in the blockchain network reach a consensus on the transaction information, The public configuration parameter is updated at a time point corresponding to the update timing. The technical solution of this embodiment enables each blockchain node to update the common configuration parameters at the same time point, and avoids the confusion caused by the adoption of different public configuration parameters by different blockchain nodes due to different update timings of the common configuration parameters. The problem.

In an embodiment of the present application, as described above, the update timing may be added to the above-mentioned transaction information to be broadcast in a blockchain network, and the update timing may be a specified block height.

In an embodiment of the present application, after the public configuration parameters are updated according to the update information, a block to be confirmed in the blockchain network needs to be confirmed based on the updated public configuration parameters; and / or Adjust the consensus strategy based on the updated public configuration parameters. For example, if the size of a block is updated, the block to be confirmed needs to be confirmed according to the new block size after the update; for another example, if the number of blockchain nodes changes, then the When voting for a consensus mechanism, the conditions for reaching a consensus (that is, how many nodes are deemed to reach a consensus when they vote for confirmation) need to be updated according to the number of updated blockchain nodes.

In an embodiment of the present application, when a node receives a block to be confirmed, it may determine whether the generation time of the block to be confirmed is before the update time point of the public configuration parameter, and if the generation time of the block to be confirmed is Before the update time of the public configuration parameters, the block to be confirmed can be confirmed based on the public configuration parameters before the update; if the generation time of the block to be confirmed is after the update time of the public configuration parameters, the The updated public configuration parameters confirm the block to be confirmed.

The technical solution of this embodiment can be based on the fact that when certain nodes receive the previously to-be-confirmed block (that is, the block generated before the update time point of the public configuration parameters) due to network delay, disconnection, downtime, etc., it can be based on Update the previous public configuration parameters (such as block size, etc.) to confirm the block to be confirmed to ensure consistency with the confirmation mechanism of other blockchain nodes.

The foregoing embodiment describes the technical solution of the embodiment of the present application from the node side that broadcasts the transaction information and the node side that receives the transaction information. The following uses the alliance chain network using a voting-based consensus mechanism as an example, as shown in FIG. The system framework describes the processing of these two nodes:

In an embodiment of the present application, for example, if the number of nodes in the alliance chain network needs to be adjusted, then node 101 (may also be

node

102, 103, 104, 105, or 106. In this embodiment, node 101 is used as an example. (Description) You can set the type of a transaction to "change node", and set the transaction content to a new node list and a specified block height (the specified block height identifies the update timing) , And then broadcast the transaction to the affiliate chain network.

After the node in the alliance chain network (such as

node

102, 103, 104, 105 or 106, or node 101) receives the transaction, it can add the information of the transaction to the block (the block may also contain There are other transaction information), and then broadcast the block in the alliance chain network to facilitate the voting confirmation of each node.

After each node in the alliance chain network has voted and reached a consensus, each node can add the block to the locally maintained alliance chain, and update the local at the specified block height based on the new node list included in the transaction content. Maintained node list. At the same time, you can also update the consensus strategy and the verification and confirmation strategy for the block.

In summary, the technical solution of the embodiment of the present application broadcasts the update information of the common configuration parameters as transaction information in the blockchain network, so that after the nodes in the blockchain network reach a consensus on the transaction information, based on the update The information updates the public configuration parameters, achieving the purpose of updating the public configuration parameters during the operation of the blockchain node, realizing the dynamic update of the public configuration parameters, and improving the update efficiency of the public configuration parameters. At the same time, since each node can update the common configuration parameters at the same update timing, it is also possible to avoid consensus problems caused by different common configuration parameters.
