Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, 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 invention.
The block chain technology is realized on a block chain network, distributed node equipment (hereinafter referred to as nodes) in the block chain network realizes generation and consensus of block data by operating a block chain program, finally realizes a tamper-proof mechanism of the data, and provides a safe and reliable new technical idea for business development.
With the increasing demand of services, the demand of developing services across block chain networks is generated, and accordingly, one or more cross-chain technologies are born. In a practical application scenario, multiple nodes of an enterprise may be distributed in one or more blockchain networks for geographic, technical, or business reasons. The multiple nodes of the enterprise are regarded as a node organization, and the operation and maintenance are carried out by the enterprise. However, due to the high complexity of the cross-chaining technique, effective management of the node organization has not been achieved. Particularly, when a certain enterprise has an illegal behavior, cross-link business is threatened because the management cannot be implemented on the node organization of the enterprise.
In view of this, the present invention provides a node organization management method, apparatus, electronic device and readable storage medium through the following embodiments, which aim to improve the supervision capability of the cross-chain technology.
Referring to fig. 1, fig. 1 is a schematic diagram of a cross-chain service system according to an embodiment of the present invention. As shown in fig. 1, the cross-chain service system includes a main blockchain network and a plurality of sub-blockchain networks, each sub-blockchain network may communicate with the main blockchain network, and every two sub-blockchain networks may also communicate with each other.
Alternatively, in some embodiments, as shown in fig. 1, each of the sub-blockchain networks has a gateway, and each of the sub-blockchain networks can communicate with the main-blockchain network through its gateway, and every two sub-blockchain networks can communicate with each other through their respective gateways.
In the invention, the sub-blockchain network is usually a private chain or an alliance chain, one sub-blockchain network can carry out relatively private services, and a cross-chain service can be carried out between two sub-blockchain networks. The roles of the master blockchain network include, but are not limited to: witness is carried out on the cross-link service between the two sub-blockchain networks, and supervision is carried out on each sub-blockchain network.
In practicing the present invention, as previously described, one or more nodes of an enterprise may be distributed across one or more blockchain networks for geographic, technical, or business reasons. One or more nodes of the enterprise are treated as a node organization, and the operation and maintenance are carried out by the enterprise. For ease of understanding, bank X illustratively has a total of 20 nodes, with 10 nodes deployed in the sub-blockchain network a, 6 nodes deployed in the sub-blockchain network c, and the remaining 4 nodes deployed in the main blockchain network. Bank Y has a total of 15 nodes, of which 12 are deployed in the sub-blockchain network b and the remaining 3 are deployed in the sub-blockchain network c.
In the invention, each node of the master blockchain network maintains a view (view) of the master blockchain network locally, and the view of the master blockchain network is used for recording node information of each node of the master blockchain network. Wherein, the node information includes but is not limited to: a node ID and a node public key. For ease of understanding, assuming, by way of example, that 32 nodes, node m1, node m2.. node m32, etc., are included in the master blockchain network, a local view of each node of the master blockchain network is shown in table 1.
Table 1 schematic view of each node in a master block chain network
| Node ID | m1 | m2 | ... | m32 |
| Node public key | ssh...1zuUF | ssh...prrX8 | ... | ssh...jYNby |
Before any node of the master blockchain network sends information to other nodes of the master blockchain network, other nodes needing to receive information need to be found from the local view of the node, and then the node can send information to the other nodes. Similarly, when receiving information sent by other nodes, the node needs to search the public key of the other node from the local view thereof, so as to perform signature verification on the received information according to the searched public key. Therefore, communication among all nodes in the main block chain network depends on the local view of all the nodes. If the node information of a certain node is not recorded in the view, the node cannot communicate with each node of the master blockchain network, so that the node is not in the master blockchain network.
Likewise, each node of the sub-blockchain network individually maintains a view (view) of the sub-blockchain network locally thereto, the view of the sub-blockchain network being used to record node information of each node of the sub-blockchain network. Wherein, the node information includes but is not limited to: a node ID and a node public key. For ease of understanding, it is exemplarily assumed that 40 nodes, such as node a1, node a2.. node a40, are included in the sub-blockchain network a, and a local view of each node is shown in table 2.
Table 2 schematic view of each node of the sub-block chain network a
| Node ID | a1 | a2 | ... | A40 |
| Node public key | ssh...UFrvi | ssh...M7xlE | ... | ssh...JW9jb |
Before sending information to other nodes of the sub-blockchain network, any node of the sub-blockchain network needs to find other nodes needing to receive information from a local view of the node, and then can send information to the other nodes. Similarly, when receiving information sent by other nodes, the node needs to search the public key of the other node from the local view thereof, so as to perform signature verification on the received information according to the searched public key. Therefore, communication among the nodes in the sub-blockchain network depends on the local view of each node. If the node information of a certain node is not recorded in the view, the node cannot communicate with each node of the sub-blockchain network, so that the node is not in the sub-blockchain network.
In order to improve the supervision capability of the cross-chain technology, referring to fig. 2, fig. 2 is a flowchart of a node organization management method according to an embodiment of the present invention. As mentioned before, the node organization comprises at least one node, which is distributed in at least one blockchain network. The node organization management method is applied to the nodes of the master blockchain network, and as shown in fig. 2, the node organization management method comprises the following steps:
step S21: acquiring endorsement information of a node organization deletion transaction and a plurality of endorsement nodes for organizing the deletion transaction to the node respectively; wherein the node organization deletion transaction specifies a target node organization to be deleted.
Each endorsement node organizes the endorsement information of the deletion transaction by the node, and the endorsement information refers to: information characterizing whether the endorsement node agrees to perform the node-organized delete transaction. For example, the endorsement information for each endorsement node may be in the form of a "yes" or a "no". If the endorsement information of one endorsement node is 'yes', the endorsement node is characterized to agree to execute the node organization deletion transaction, namely, the endorsement passes through. If the endorsement information of one endorsement node is 'no', the endorsement node is not authorized to execute the node organization deletion transaction, namely, the endorsement does not pass.
Optionally, in some embodiments, each endorsement node is a node in a master blockchain network. In the invention, the node in the main blockchain network is taken as an endorsement node to endorse the node organization deletion transaction, so that the supervision capability of the main blockchain network on each sub-blockchain network can be further enhanced.
In the specific implementation of the invention, when any node in the main block chain network responds to the operation of a node administrator to generate a node organization deletion transaction, the node sends the node organization deletion transaction to an endorsement node cluster appointed by the endorsement rule according to the preset endorsement rule. After each endorsement node in each endorsement node cluster receives the node organization deletion transaction, the endorsement can be automatically performed on the node organization deletion transaction according to the target node organization to be deleted specified in the node organization deletion transaction, and the endorsement information is signed. Or the node organization deletion transaction can be notified to an administrator of the endorsement node, endorsement information input by the administrator is accepted, and endorsement information input by the administrator is signed. Then, each endorsement node returns the endorsement information after signature to the node.
After the nodes receive endorsement information of each endorsement node, each endorsement information can be filled into the node organization deletion transaction, and then the node organization deletion transaction filled with the endorsement information is submitted to the sequencing nodes of the main block chain network. After receiving the node organization deletion transaction, the sequencing node sequences and packages the node organization deletion transaction and other transactions received by the node organization deletion transaction and the other transactions received by the node organization deletion transaction at the same time to generate a transaction package. And the sequencing node distributes the generated transaction package to each node in the main blockchain network. After each node receives the transaction package, reading the node organization deletion transaction from the transaction package, and reading endorsement information filled in the node organization deletion transaction. In this way, the nodes of the master blockchain network obtain endorsement information for organizing the deletion transaction by the nodes and organizing the deletion transaction by each of the plurality of endorsement nodes for the nodes.
Or alternatively, in other embodiments, the endorsement node may also be a device outside the master blockchain network, and these devices do not necessarily have to be nodes of the blockchain network. For example, these devices may be supervisor's terminal devices that do not join any blockchain network.
Step S22: and verifying the legality of the node organization deletion transaction according to the endorsement information.
In the invention, after the node of the main block chain network obtains the node organization deletion transaction and the endorsement information, the validity of the node organization deletion transaction is verified according to the endorsement information. And when the node organization deletion transaction is legal, the subsequent node organization deletion process is continuously executed. And under the condition that the node organization deletion transaction is illegal, the node organization deletion process is terminated. Therefore, the method can prevent the illegal node organization deleting transaction from being executed by mistake, and the node organization from being deleted by mistake.
Optionally, in some embodiments, the plurality of endorsement nodes participating in endorsement belong to one or more endorsement node clusters, as previously described. Each node of the master blockchain network is preset with an endorsement verification policy (policy), and a transaction validity verification rule is agreed in the endorsement verification policy. The node of the main block chain network verifies the validity of the node organization deletion transaction according to the endorsement information, and specifically comprises the following steps: determining an endorsement result of each endorsement node cluster according to the endorsement information of each endorsement node in the endorsement node cluster and the endorsement verification strategy; if the endorsement information of at least one endorsement node in the endorsement node cluster is endorsement passing, determining that the endorsement result of the endorsement node cluster is endorsement passing; and determining the total endorsement result according to the endorsement result of each endorsement node cluster and the endorsement verification strategy.
For ease of understanding, assume, by way of example, that the transaction validity validation rules agreed in the endorsement validation policy are: for each endorsement node cluster, if the endorsement information of at least one endorsement node in the endorsement node cluster is that the endorsement passes, determining that the endorsement result of the endorsement node cluster is that the endorsement passes; and in all endorsement node clusters, if the endorsement results of more than half of the endorsement node clusters are endorsement passing, determining that the total endorsement result is endorsement passing.
Assuming that 20 endorsement nodes are totally involved in endorsement of the node organization deletion transaction, 12 endorsement nodes in the 20 endorsement nodes are operated and maintained by a regulatory agency x, and the 12 endorsement nodes belong to an endorsement node cluster x. And 5 endorsement nodes are operated and maintained by a supervision organization y, and the 5 endorsement nodes belong to an endorsement node cluster y. The other 3 endorsement nodes are operated and maintained by a supervision organization z, and the 3 endorsement nodes belong to an endorsement node cluster z.
And assuming that the endorsement information of 8 endorsement nodes in the 12 endorsement nodes of the endorsement node cluster x passes the endorsement and the endorsement information of the other 4 endorsement nodes does not pass the endorsement, the endorsement result of the endorsement node cluster x passes the endorsement. In the 5 endorsement nodes of the endorsement node cluster y, the endorsement information of 2 endorsement nodes is that the endorsement passes, and the endorsement information of the other 3 endorsement nodes is that the endorsement does not pass, so that the endorsement result of the endorsement node cluster y is that the endorsement passes. In the 3 endorsement nodes of the endorsement node cluster z, the endorsement information of the 3 endorsement nodes is that the endorsement does not pass, and the endorsement result of the endorsement node cluster z is that the endorsement does not pass.
The endorsement results of the endorsement node cluster x and the endorsement node cluster y are endorsement passing results, and the endorsement results of the endorsement node cluster z are endorsement failing results. Therefore, in all 3 endorsement node clusters, endorsement results of more than half of endorsement node clusters are endorsement passes, and further the total endorsement result is determined to be endorsement passes.
It should be noted that, in the present invention, a plurality of endorsement nodes are divided into a plurality of endorsement node clusters, and for each endorsement node cluster, all endorsement information in the endorsement node cluster is integrated into one endorsement result, and then the total endorsement result is determined according to the respective endorsement results of the plurality of endorsement node clusters. Therefore, the situation that some monitoring authorities (such as the monitoring authority x) possess most endorsement nodes to cause the absolute speaking right in the endorsement link and further cause the lack of fairness in the endorsement link can be avoided. In other words, in the invention, by processing the endorsement information in the above manner, the fairness of the endorsement link can be improved, and further the fairness of the node organization management can be improved.
In addition, it should be noted that, under some coincidence, some nodes in the target node organization to be deleted may be exactly endorsement nodes, and these endorsement nodes to be deleted may unfairly give endorsement information that endorsements do not pass through when performing endorsement. In view of the above situation, in the present invention, for each endorsement node cluster, if the endorsement information of at least one endorsement node in the endorsement node cluster is an endorsement pass, it is determined that the endorsement result of the endorsement node cluster is an endorsement pass. Therefore, the obstruction of unfairness endorsement information of the endorsement node to the node organization deletion can be avoided as much as possible.
Or alternatively, in other embodiments, considering that part of nodes in the target node organization to be deleted may be just endorsement nodes, when the target node organization is deleted, the endorsement verification policy may be disabled, and then the deletion operation on the node organization cannot be performed again in the following. For this purpose, the nodes of the master blockchain network perform, in order to verify the validity of the node organization deletion transaction, in particular, the following sub-steps:
substep S22-1: and determining whether the total endorsement result is an endorsement passing result or not according to a preset endorsement verification strategy and the endorsement information of each endorsement node.
In specific implementation, referring to the foregoing specific embodiment, the endorsement nodes belong to one or more endorsement node clusters, and for each endorsement node cluster, an endorsement result of the endorsement node cluster is determined according to the endorsement information of each endorsement node in the endorsement node cluster and the endorsement verification policy; if the endorsement information of at least one endorsement node in the endorsement node cluster is endorsement passing, determining that the endorsement result of the endorsement node cluster is endorsement passing; and determining the total endorsement result according to the endorsement result of each endorsement node cluster and the endorsement verification strategy.
Substep S22-2: and judging whether the endorsement verification strategy fails after each node in the target node organization is deleted.
During specific implementation, the node of the main block chain network judges whether the node belongs to the endorsement node or not aiming at each node in the target node organization; then, aiming at a plurality of nodes belonging to endorsement nodes in the target node organization, judging whether the rest endorsement nodes meet the requirements of the endorsement verification strategy on the endorsement nodes after the plurality of nodes are deleted; if yes, determining that the endorsement verification strategy is invalid after all nodes in the target node organization are deleted; if not, determining that the endorsement verification strategy is not invalid after all nodes in the target node organization are deleted.
For ease of understanding, it is assumed by way of example that the endorsement verification policy is defined as: the number of endorsement node clusters should not be below 3. Following the above example, it is again assumed that the current endorsement node clusters include endorsement node cluster x, endorsement node cluster y, and endorsement node cluster z. The endorsement node cluster x comprises 12 endorsement nodes, the endorsement node cluster y comprises 5 endorsement nodes, and the endorsement node cluster z comprises 3 endorsement nodes.
And then, assuming that the current target node organization needing to be deleted comprises 8 nodes to be deleted, judging whether the node belongs to the endorsement node or not by the node of the main block chain network aiming at each node in the 8 nodes, and determining which endorsement node cluster the node specifically belongs to. Suppose that 1 node of the 8 nodes belongs to the endorsement node cluster x and 3 nodes belong to the endorsement node cluster z. Then if the target node organization is deleted, there will still be 11 endorsement nodes in endorsement node cluster x, 5 endorsement nodes in endorsement node cluster y, and 0 endorsement node in endorsement node cluster z. It can be seen that if the target node organization is deleted, the endorsement node cluster z is deleted, which results in the number of endorsement node clusters being changed to 2, which is lower than the minimum number 3 defined in the endorsement verification policy, and the endorsement verification policy is invalid.
It should be noted that, the above process of determining whether the endorsement verification policy is invalid is taken as an example of the present invention, and other determination manners may also be adopted in the specific implementation of the present invention. For example, the endorsement verification policy defines the necessary endorsement nodes that must participate in the endorsement stage. If the target node organization contains the necessary endorsement nodes, the necessary endorsement nodes can be deleted after the target node organization is deleted. It can be determined that: after each node in the target node organization is deleted, the endorsement verification strategy can be invalid.
Substep S22-3: and determining that the node organization deletion transaction is legal under the condition that the total endorsement result is that the endorsement passes and the endorsement verification strategy is not invalid after each node in the target node organization is deleted.
In addition, when the total endorsement result is that the endorsement passes but the endorsement verification strategy is invalid after each node in the target node organization is deleted, the node organization deletion transaction is determined to be illegal.
And determining that the node organization deletion transaction is illegal under the condition that the total endorsement result is that the endorsement does not pass and the endorsement verification strategy cannot be invalidated after each node in the target node organization is deleted.
And determining that the node organization deletion transaction is illegal under the condition that the total endorsement result is that the endorsement does not pass and the endorsement verification strategy is invalid after each node in the target node organization is deleted.
Step S23: and under the condition that the node organization deletion transaction is legal, deleting the node information belonging to the target node organization from a local view by executing the node organization deletion transaction, wherein the local view is used for recording the node information of each node of the master block chain network.
In the invention, under the condition that the node organization deletion transaction is illegal, the whole node organization deletion process can be terminated so as to avoid the node organization from being deleted by mistake.
And under the condition that the node organization deletion transaction is legal, node information belonging to the target node organization is deleted from the local view by executing the node organization deletion transaction, so that the nodes belonging to the master blockchain network in the target node organization are quitted from the master blockchain network.
For ease of understanding, following the above example, a local view of the nodes of the master blockchain network is shown in table 1 above, in which node information of 32 nodes, such as node m1, node m2. Assume that the target node organization includes 8 nodes, which are node m2, node m3, node m4, node m24, node a1, node a6, node a7, and node a10, respectively. In this way, each node of the master blockchain network deletes the node information belonging to the target node organization from the local view by executing the node organization deletion transaction, so as to update the local view, and the updated local view is shown in table 3.
Table 3 updated view schematic table of each node of master block chain network
| Node ID | m1 | m5 | ... | m32 |
| Node public key | ssh...1zuUF | ssh...uayrD | ... | ssh...jYNby |
In the updated view shown in table 3, the node information of the node m2, the node m3, the node m4, and the node m24 is deleted, compared to the view before update shown in table 1. For other nodes except the 4 nodes in the main blockchain network, the nodes do not perform intra-chain communication with the 4 nodes any more because the local views of the nodes do not record the node information of the 4 nodes any more. Thus, nodes m2, m3, m4, and m24 are equivalent to exiting from the master block chain network.
Optionally, in some specific embodiments, a node organization table is stored in the ledger database of each node of the master block chain network, and an organization ID of each node organization is recorded in the node organization table, and node information under each organization ID is also recorded. For ease of understanding, the node organization table is shown in Table 4, by way of example.
Table 4 node organization table
The node organization deletion transaction carries an organization ID of a target node organization to be deleted, and when the node of the master blockchain network executes the step S23, specifically, the node of the master blockchain network executes the following sub-steps:
substep S23-1: and under the condition that the node organization deletion transaction is legal, the node organization deletion transaction is executed, and the organization ID carried by the node organization deletion transaction and the node information under the organization ID are deleted from the local node organization table or marked as a deletion state in the local node organization table.
For convenience of understanding, by way of example, assuming that the organization ID carried in the node organization deletion transaction is D1, it is explained that the target node to be deleted is organized as node organization D1. After the nodes of the master blockchain network execute the above steps S21 and S22, if it is determined that the node organization deletion transaction is legal, the nodes of the master blockchain network organize the deletion transaction by executing the nodes, and delete the node information under D1 and D1 from the local node organization table to update the node organization table, where the updated node organization table is shown in table 5.
Table 5 updated node organization table
In the updated node organization table shown in table 5, node information under the entries of node organization D1 and node organization D1 is deleted, compared to the node organization table before update shown in table 4.
Substep S23-2: and deleting the corresponding node information from the local view according to the node information under the node organization ID in the node organization table.
To facilitate understanding, following the above example, the nodes of the master blockchain network are queried from the node organization table before updating to the nodes under node organization D1 including: 8 nodes, node m2, node m3, node m4, node m24, node a1, node a6, node a7, and node a 10. Since node m2, node m3, node m4, and node m24 belong to the master blockchain network, the nodes of the master blockchain network delete the node information of node m2, node m3, node m4, and node m24 from their local view.
It should be noted that, in the foregoing specific embodiment, in the node organization deletion transaction, it is not necessary to carry each node information in the target node organization, but only an organization ID of the target node organization, so that the length of the node organization deletion transaction can be effectively reduced. When the node of the master block chain network executes the node organization deletion transaction, the node information under the organization ID can be determined from the node organization table by taking the organization ID as an index, so that the corresponding node information in the local view is deleted. In addition, each node of the master blockchain network is favorable for further improving the supervision capability of the master blockchain network by maintaining and updating the node organization table.
Step S24: and after executing the node organization deletion transaction, sending the node organization deletion transaction to each sub-block chain network, so that each node of each sub-block chain network deletes the node information belonging to the target node organization from a local view by executing the node organization deletion transaction, wherein the local view is used for recording the node information of each node of the sub-block chain network.
In the invention, the node organization deletion transaction is sent to each sub-block chain network, so that each node of the sub-block chain network deletes the node information belonging to the target node organization from the local view by executing the node organization deletion transaction. In this way, nodes belonging to the sub-blockchain network in the target node organization are caused to exit from the sub-blockchain network.
For ease of understanding, following the above example, the target node organization to be deleted includes 8 nodes, which are node m2, node m3, node m4, node m24, node a1, node a6, node a7, and node a10, respectively. Each node of the sub-block chain network a deletes the node information belonging to the target node organization from the local view by executing the node organization deletion transaction, so as to update the local view, and the updated local view is shown in table 6.

In the updated view shown in table 6, the node information of the node a1, the node a6, the node a7, and the node a10 is deleted, compared to the view before update shown in table 2. For other nodes except for the 4 nodes in the sub-blockchain network a, since the node information of the 4 nodes is no longer recorded in the local view of the nodes, the nodes do not perform intra-chain communication with the 4 nodes. Thus, nodes a1, a6, a7, and a10 are equivalent to exiting the subchunk chain network a.
Optionally, in some embodiments, when the sub-blockchain network a executes the node organization deletion transaction, the specific execution process may refer to the foregoing sub-step S23-1 and sub-step S23-2. In order to avoid repetition, the specific process of executing the node organization deletion transaction on the sub-block chain network a is not described herein again.
Because the target node organization to be deleted does not include the node of the sub-blockchain network b, the local view of the node is not updated after the node organization deletion transaction is executed by the node of the sub-blockchain network b. Similarly, since the target node organization to be deleted does not include the node of the subzone chain network c, the node of the subzone chain network c does not update the local view of the node after executing the node organization deletion transaction.
Optionally, in some embodiments, in order to send the node organization deletion transaction to each of the sub-blockchain networks, the node of the main blockchain network may perform the following sub-steps:
substep S24-1: after the node organization deletion transaction is executed, the node organization deletion transaction is used as block data for generating a new block, and therefore the new block is generated.
In particular implementations, the node reads the transaction from the transaction package and executes it, as previously described. The node may generate a new tile by using transactions and execution results of the transactions in a transaction package as tile data for generating a new tile. The execution result of the transaction is like "yes" or "no". If the execution result of one transaction is "yes", the transaction is indicated to be successfully executed by the master blockchain network. And if the execution result of one transaction is 'no', the transaction is not successfully executed by the master block chain network.
Substep S24-2: and combining other nodes of the main block chain network to carry out consensus on the new blocks.
In specific implementation, each node of the master block chain network generates a new block by executing the steps. When the nodes mutually identify the respective generated blocks, the specific identification manner may be: and each node calculates a root hash value according to the block body of the generated block and sends the calculated root hash value to other nodes. Correspondingly, each node also receives the root hash value sent by other nodes. And each node compares the received root hash values with the self-calculated root hash values one by one, and if the root hash values exceeding the preset number are equal to the self-calculated root hash values, the nodes determine that the generated blocks pass consensus. For ease of understanding, the above-mentioned preset number may be equal to 51% of the total number of nodes of the blockchain network, for example.
Substep S24-3: and after the new block passes the consensus, sending the new block to each sub-block chain network, so that each sub-block chain network reads the node organization deletion transaction from the new block.
In specific implementation, after determining that the generated block passes the consensus, the node in the main blockchain network may send the generated block to the gateway of each sub-blockchain network. After receiving the block, the gateway of each sub-blockchain network synchronizes the block to each node in the sub-blockchain network. In this way, each node of the sub-blockchain network obtains a block of the main blockchain network, and can read from the block to the node organization deletion transaction.
In the invention, the transaction in the block is the transaction which is executed by the main block chain network and passes the consensus. Therefore, the invention sends the node organization deletion transaction to the sub-blockchain network in a block mode, and can ensure the execution sequence of the node organization deletion transaction, namely the node organization deletion transaction needs to be executed by the main blockchain network with supervision capability and then executed by each sub-blockchain network. Therefore, the reliability of the node organization deleting process is further improved.
Furthermore, the nodes of the master blockchain network may also continuously synchronize blocks to the sub-blockchain network. Specifically, each time a new block is generated by a node of the main blockchain network, and after the new block is identified, the new block is synchronized to the sub-blockchain network. Or, the node of the main blockchain network receives a synchronization request of the sub blockchain network, and synchronizes the newly generated and shared blocks to the sub blockchain network in response to the synchronization request.
