Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. 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.
As shown in fig. 1, which is a flowchart illustrating a method for identifying a blockchain according to an embodiment of the present invention, the method includes the following steps:
step 101: when detecting that a first node set in a plurality of node sets in a block chain network generates service data to be confirmed, controlling a verification node in the first node set and each common identification node in the common identification set to carry out validity verification on the service data to be confirmed.
In this step, specifically, the node set is obtained by aggregating seed nodes authorized in advance, and the consensus nodes in the consensus set are obtained by electing from each node set respectively.
In addition, specifically, in this embodiment, a preset number of nodes in the first node set may be defined as the verification nodes in advance, that is, when the blockchain network is started, the preset number of verification nodes in the first node set may be initialized.
In this way, in this embodiment, first all nodes in the blockchain network are aggregated to obtain a plurality of node sets, and then at least one consensus node is elected from each node set to form a consensus set, so that when service data to be confirmed is generated in the blockchain network, which node set is generated can be known definitely. At this time, if it is detected that any one node set (defined as a first node set) in the plurality of node sets generates the service data to be confirmed, each common identification node in the first node set and the common identification set may be directly controlled to perform validity verification on the service data to be confirmed, so that validity verification efficiency is ensured and validity verification accuracy is provided.
When the verification node in the first node set and each common identification node in the common identification set are controlled to carry out validity verification on the service data to be confirmed, when the first node set in a plurality of node sets in a block chain network is detected to generate the service data to be confirmed, the verification node in the first node set is controlled to carry out validity verification on the service data to be confirmed; then when the verification node verifies that the service data to be confirmed is legal, controlling the node generating the service data to be confirmed in the first node set to flood the service data to be confirmed to each node in the first node set; and finally, when detecting that the common identification node obtained by election in the first node set receives the service data to be confirmed, controlling the common identification node obtained by election in the first node set to flood the service data to be confirmed to each common identification node in the common identification set, and controlling each common identification node in the common identification set to respectively carry out validity verification on the service data to be confirmed.
Specifically, each common node in the common node set is generated by a node in the node set, so that when the service data to be confirmed is flooded to each node in the first node set, the service data to be confirmed is flooded to the common node generated in the first node set, and at this time, the first node set and the common node set establish a connection based on the common node, so that the common node in the first node set can be controlled to flood the service data to be confirmed to each common node in the common node set.
Therefore, when the first node set verifies that the service data to be confirmed is legal and floods to each node in the first set, the common identification node selected from the first node set is controlled to flood the service data to be confirmed to each common identification node in the common identification set, complexity of a confirming process of illegal service data to be confirmed is avoided, and filtering efficiency of illegal service data to be confirmed is improved.
Step 102: when detecting that the verification node in the first node set and each common identification node in the common identification set verify that the service data to be confirmed is legal, controlling an accounting node in the common identification set to account for the service data to be confirmed in a preset time range and generating a block.
In this step, specifically, the accounting node is randomly obtained from the consensus nodes in the consensus set. That is, when the consensus set is obtained by election, an accounting node can be selected from the consensus set by using a random algorithm, and the accounting node accounts the service data to be confirmed in a preset time range and generates a block.
It should be noted that, one accounting node records all the to-be-confirmed service data in a preset time range according to the time stamp, and another accounting node can concurrently account for the to-be-confirmed service data in another time range at the same time, that is, different accounting nodes can concurrently record the to-be-confirmed service data in different time ranges, so as to ensure the accounting efficiency.
Step 103: and controlling each consensus node in the consensus set to perform consensus on the blocks.
In this step, specifically, after the block is generated by the accounting node, each consensus node in the consensus set may be controlled to perform consensus on the block.
When controlling each consensus node in the consensus set to perform consensus on the block, the accounting node in the consensus set may be controlled to flood the block to each consensus node in the consensus set, and control each consensus node in the consensus set to perform consensus on the block respectively.
Specifically, since the accounting node is a randomly selected consensus node in the consensus set, the accounting node can be directly controlled to flood the block to each consensus node in the consensus set, so that consensus of each consensus node on the block is completed.
In addition, after controlling each common node in the common node set to perform common identification on the block, for each common node in the common node set, controlling each common node to forward the block to the node set elected to obtain the common node, so that the node set forwarded to obtain the block completes flooding on the block.
Therefore, after each common node in the common identification set performs common identification on the block, the common node in the common identification set can be controlled to forward the block to the node set generating the common node, and the common node is generated in each node set, so that the block can be forwarded to all the node sets, the block can be controlled to flood to all the nodes in all the node sets, and the uplink process of all the nodes in the block chain network is completed.
In this embodiment, all nodes in the block chain network are aggregated to obtain a plurality of node sets, then at least one consensus node is obtained from each node set to form a consensus set, when it is detected that a first node set in the plurality of node sets generates service data to be confirmed and the first node set and the consensus set both verify that the service data to be confirmed is legal, the accounting node generated in the consensus set is controlled to account the service data to be confirmed and generate a block, then each consensus node in the consensus set is controlled to perform consensus on the block, so that the service data to be confirmed newly generated in the block chain network can be quickly verified by the consensus node and generate a block, and thus the newly generated block can be quickly identified by the consensus node in the consensus set, and further based on the relationship between the consensus set and the node sets, the method achieves the total network consensus, improves the consensus efficiency of the blocks in the block chain network, achieves the rapid achievement of the total network consensus in the block chain network of the alliance, and solves the problem of low consensus efficiency in the prior art.
Further, before controlling each of the verification node in the first node set and the consensus node in the consensus set to perform validity verification on the service data to be confirmed, the node set and the consensus set in the block chain network also need to be acquired.
Specifically, when the node set and the consensus set in the block chain network are obtained, a plurality of seed nodes authorized in advance and the block forwarding times of each node in the block chain network may be obtained first; then according to the block forwarding times of each node in the block chain network, all nodes in the block chain network are aggregated to obtain a plurality of node sets respectively based on at least one seed node; aiming at each node set, controlling other node sets except the aimed node set in the node sets to select at least one consensus node from the aimed node set through a preset election algorithm; and finally, forming the consensus set by all the consensus nodes elected from all the node sets.
Specifically, in this embodiment, a node authorized offline in advance may be recorded as a seed node, and the seed node authorized offline is generated in each service system owned by a federation member in the area chain network, has stable bandwidth and storage resources, and can ensure online time. In addition, the number of the seed nodes is larger than that of the node sets, and each node set can be rebuilt according to a time period so as to ensure the accuracy of the established node sets.
In addition, specifically, it should be noted that in this embodiment, when all nodes in the blockchain network are aggregated based on at least one seed node to obtain a plurality of node sets, the nodes with the block forwarding times greater than the preset value may be aggregated to obtain one node set based on one seed node, and the nodes with the block forwarding times greater than the preset value may also be aggregated to obtain one node set based on more than two seed nodes until all nodes are aggregated, that is, the number of seed nodes included in one node set is not limited herein.
In addition, specifically, the nodes in the node set include nodes at the same level and/or multiple levels of nodes, that is, the present embodiment does not limit the number of levels in which the nodes are located, so that a multi-level dynamic node set is adopted, which provides convenience for consensus of a federation chain.
In addition, specifically, after the node set is obtained, other node sets may be controlled to obtain the consensus node of the node set through election by using a preset election algorithm. Wherein the number of all the consensus nodes elected from all the node sets is an odd number. Of course, the number of consensus nodes generated by electing within a node set is not limited herein, and the consensus set is re-elected as the node set is established. The conditions of the preset election algorithm may include a network response speed, a lifetime in the blockchain network, and the like.
In this way, in this embodiment, by acquiring the node set and the consensus set in the blockchain network, the service data to be confirmed and the block can be verified and consensus in the node set and the consensus set, and based on the relationship that all the consensus nodes in one consensus set are from all the node sets, the consensus efficiency of the block is provided.
