For example, the electronic device may implement the steps shown in fig. 3 and 4.
The implementation details of the technical scheme of the embodiment of the invention are explained in detail as follows:
fig. 3 schematically shows a flowchart of a management method of a blockchain network according to an embodiment of the present invention, which is applicable to the electronic device described in the foregoing embodiments. Referring to fig. 3, the management method of the blockchain network at least includes steps S310 to S330, which are described in detail as follows:
in step S310, update information of common configuration parameters in the blockchain network is acquired.
In an embodiment of the present invention, the blockchain network may be a public chain network, a private chain network, or a alliance chain network, and the common configuration parameter may refer to basic information required for generating the blockchain network, and may include the number of blockchain links, the size of one block, how often one block is generated, and the like.
In step S320, transaction information of the blockchain network is generated according to the update information.
In an embodiment of the present invention, since the transaction information includes a transaction type (i.e. type) and transaction content (i.e. data), the transaction content may be generated according to the update information of the common configuration parameter, and the transaction type may be configured as a type for modifying the common configuration parameter, so as to generate the transaction information based on the transaction content and the transaction type.
For example, for the update information of the number of nodes, the transaction information may be generated with a transaction type of "change node" and the transaction content of the updated node list.
In step S330, the transaction information is broadcasted in the blockchain network, so that the nodes in the blockchain network update the common configuration parameters according to the transaction information after agreeing on the transaction information.
The technical solution of the embodiment shown in fig. 3 enables the update information of the common configuration parameter to be broadcast as the transaction information in the blockchain network, so that after the node in the blockchain network agrees with the transaction information, the common configuration parameter is updated based on the update information, thereby achieving the purpose of updating the common configuration parameter in the operation of the blockchain nodes and improving the update efficiency of the common configuration parameter.
Based on the technical solution of the embodiment shown in fig. 3, in an embodiment of the present invention, an update time of the common configuration parameter may also be broadcasted in a blockchain network, so that a node in the blockchain network updates the common configuration parameter at a time point corresponding to the update time. According to the technical scheme of the embodiment, the common configuration parameters can be updated at the same time point by each block link point, and the problem that the common configuration parameters are adopted due to different updating opportunities of the common configuration parameters by each block link point is solved. For example, some block chain nodes update the common configuration parameters first, and other block chain nodes update after a period of time, and in this period of time, because the block chain nodes adopt different common configuration parameters, the consensus strategies of the block chain nodes are different, and the normal operation of the block chain network is affected.
In an embodiment of the present invention, the update timing of the common configuration parameter may be added to the transaction information (i.e. the transaction information generated by the common configuration parameter) to broadcast the update timing by broadcasting the transaction information, for example, the update timing may be added to the transaction content.
In an embodiment of the present invention, the update timing of the common configuration parameter may include a specified block height, i.e. the specified block height is broadcasted in the blockchain network as the update timing of the common configuration parameter. The block height is an identifier of the block, and since the block has a certain generation time, when the generated block reaches the specified block height, the update timing when the common configuration parameter is reached can be determined.
In an embodiment of the present invention, the difference between the height of the specified block and the height of the block in which the transaction information (i.e. the transaction information generated by the common configuration parameter) is located is a predetermined number of blocks, that is, the common configuration parameter is updated when the predetermined number of blocks are generated after the block in which the transaction information is located.
In one embodiment of the present invention, the predetermined number is positively correlated to a network delay of the blockchain network. For example, the network delay is large, the predetermined number may be set to a large value to ensure that all or most of the block nodes receive the transaction information (i.e., the transaction information generated by the common configuration parameter) and perform verification. If the network delay is small, the predetermined number may be set to a small value to update the common configuration parameters as quickly as possible.
In a specific application scenario of the present invention, the blockchain network may be a blockchain network that employs a voting-based consensus mechanism, such as a federation chain network. Since the voting-based consensus mechanism needs to confirm the number of nodes in the network to confirm that most of the nodes vote to confirm, the consensus (usually, the consensus is achieved for the transaction information)
In the technical scheme of the embodiment of the invention, the information of adding and/or deleting nodes in the block chain network can be used as transaction information to be broadcasted in the block chain network, so that after the nodes in the block chain network agree on the transaction information, the information of the block chain nodes is updated based on the update information, the aim of updating the node information in the operation of the block chain nodes is fulfilled, the problem that the node information cannot be modified in the operation process of the block chain nodes at present is solved, and the updating efficiency of the node information is improved.
The technical solution of the above embodiment is explained from a node side broadcasting the transaction information, and the technical solution of the embodiment of the present invention is further explained from a node side receiving the transaction information.
Fig. 4 is a flowchart schematically illustrating a management method of a blockchain network according to an embodiment of the present invention, and referring to fig. 4, the method specifically includes the following steps:
step S410, transaction information broadcasted in the blockchain network is acquired.
In one embodiment of the invention, tiles broadcast in a blockchain network may be obtained and then the transaction information is obtained from the tiles.
Step S420, determining whether the transaction information includes update information of the common configuration parameter in the blockchain network.
In an embodiment of the present invention, the node broadcasting the transaction information may generate the transaction information according to the update information of the common configuration parameter of the blockchain network, so that the node receiving the transaction information may ensure whether the transaction information includes the update information of the common configuration parameter.
Step S430, if the transaction information includes the update information of the public configuration parameter, after the node in the block chain network agrees with the transaction information, updating the public configuration parameter according to the update information.
The technical solution of the embodiment shown in fig. 4 enables the node in the blockchain network to achieve consensus on the transaction information including the update information of the common configuration parameter, and then the common configuration parameter can be updated based on the update information, so that the purpose of updating the common configuration parameter in the operation of the blockchain nodes is achieved, and the update efficiency of the common configuration parameter is improved.
Based on the technical solution of the embodiment shown in fig. 4, in an embodiment of the present invention, an update time of the common configuration parameter may also be obtained, and then the common configuration parameter may be updated at a time point corresponding to the update time after the node in the block chain network agrees with the transaction information. According to the technical scheme of the embodiment, the common configuration parameters can be updated at the same time point by each block link point, and the problem that the common configuration parameters are adopted due to different updating opportunities of the common configuration parameters by each block link point is solved.
In one embodiment of the present invention, the update timing may be added to the transaction information described above for broadcasting in the blockchain network, as described above, while the update timing may be a specified blockheight.
In an embodiment of the present invention, after the common configuration parameter is updated according to the update information, the block to be confirmed in the block chain network needs to be confirmed based on the updated common configuration parameter; and/or adjusting the consensus policy based on the updated common 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 the block link nodes changes, when the consensus mechanism based on the voting is adopted, the condition for achieving the consensus (i.e., how many nodes vote for confirmation is determined to achieve the consensus) needs to be updated according to the updated number of the block link nodes.
In an embodiment of the present invention, 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 common configuration parameter, and if the generation time of the block to be confirmed is before the update time point of the common configuration parameter, the block to be confirmed may be confirmed based on the common configuration parameter before the update; if the generation time of the block to be confirmed is after the update time point of the common configuration parameter, the block to be confirmed can be confirmed based on the updated common configuration parameter.
According to the technical scheme of the embodiment, when some nodes receive the previous block to be confirmed (namely, the block generated before the update time point of the common configuration parameter) due to network delay, a drop, a downtime and the like, the block to be confirmed can be confirmed based on the common configuration parameter (such as the block size and the like) before the update, so as to ensure that the confirmation mechanism of the node is consistent with that of other blockchain nodes.
The foregoing embodiment has described the technical solutions of the embodiments of the present invention from the node side that broadcasts the transaction information and the node side that receives the transaction information, and the following takes a federation chain network that adopts a consensus mechanism based on voting as an example, and combines the system framework shown in fig. 1 to describe the processing procedures of these two nodes:
in an embodiment of the present invention, for example, if the number of nodes in the federation chain network needs to be adjusted, the node 101 (which may also be the node 102, 103, 104, 105, or 106, in this embodiment, the node 101 is taken as an example for explanation) may set the type (type) of a transaction as "change node", set the transaction content (data) as a new node list and a specified block height (the specified block height identifies an update opportunity), and then broadcast the transaction to the federation chain network.
After receiving the transaction, the node (e.g., node 102, 103, 104, 105, or 106, or node 101) in the federation chain network may add information about the transaction to the block (which may also contain other transaction information), and then broadcast the block in the federation chain network for voting confirmation by each node.
After each node in the federation chain network votes and agrees, each node may add the block to the locally maintained federation chain while updating the locally maintained list of nodes at the specified block height based on the new list of nodes contained in the transaction content. Meanwhile, the consensus strategy and the strategy for verifying and confirming the block can be updated.
In summary, according to the technical scheme of the embodiment of the present invention, the update information of the public configuration parameter is broadcast in the blockchain network as the transaction information, so that after the node in the blockchain network agrees with the transaction information, the public configuration parameter is updated based on the update information, thereby achieving the purpose of updating the public configuration parameter during the operation of the blockchain node, achieving the dynamic update of the public configuration parameter, and improving the update efficiency of the public configuration parameter. Meanwhile, each node can update the common configuration parameters at the same update time, so that the consensus problem caused by different common configuration parameters can be avoided.
The following describes an embodiment of the apparatus of the present invention, which may be used to implement the management method of the blockchain network in the above embodiment of the present invention.
