With the deep advancement of national industrial internet, "internet +" action plan, cloud computing and big data strategy, the construction of a smart internet of things system is accelerated in various industries, and the interactive construction of massive edge sides and cloud ends is promoted. The cloud edge cooperation technology provides a solution for the problems, and the core idea is to deploy part of data processing, analysis and related application programs to a marginal layer close to a data source so as to reduce data processing time delay and relieve resource pressure of a cloud platform.

s100, forming a block chain network by utilizing a block chain technology through a plurality of edge nodes, wherein the block chain network comprises a common node, a candidate node and a common node.
The edge node in this embodiment is a node located in an edge layer in the cloud edge coordination system. The edge node may be a physical node, for example, including but not limited to a server, a gateway, and the like.
Optionally, the block chain network may implement data consensus through the consensus node, thereby ensuring data security. In some embodiments, any node in the blockchain network can become a common node through registration, and if the common node in the blockchain network is authenticated as a trusted node by a trusted node or an authorized third party, the common node can be authenticated as a candidate node and generates an identity key for the candidate node, and meanwhile, the identity key is distributed to other candidate selection nodes and common identification nodes in the blockchain network for identity authentication; trusted candidate nodes (e.g., candidate nodes with higher confidence) may be identified as consensus nodes. And if the common node monitors the malicious node through abnormal behaviors, the common node can be reduced to be a common node or removed.
S200, adjusting the consensus nodes in the block chain network by adopting a dynamic change mechanism based on a PBFT consensus algorithm to obtain the dynamically changed consensus nodes;
in order to avoid hidden data safety hazards caused by data consensus performed by malicious nodes serving as consensus nodes, and further guarantee the data safety, in the embodiment of the application, the consensus nodes in the block chain network can be detected. As an example, when a malicious node exists in the consensus node, the malicious node may be reduced to a normal node or removed, and a candidate node with a higher confidence level is used as the consensus node. See the description of the embodiments that follow in detail.
And S300, performing consensus on the edge side transaction data according to the dynamically changed consensus node.
In order to better realize data consensus and guarantee data security, in the embodiment of the application, the consensus node may include a master node and a plurality of slave nodes, and the master node may alternately act in the consensus node. After acquiring the dynamically changed consensus node, the transaction data consensus may include, but is not limited to, a transaction data request, transaction data preparation, transaction data feedback, transaction data confirmation, and transaction data reply.
In the embodiment, the consensus nodes in the block chain network are adjusted by adopting a dynamic change mechanism based on a PBFT consensus algorithm to obtain the dynamically changed consensus nodes, and the consensus of the edge side transaction data is performed according to the dynamically changed consensus nodes, so that a malicious node is prevented from being used as the consensus node to perform data consensus, the security of the transaction data is ensured, and the credibility of the transaction is ensured.

s201, detecting the consensus node in the block chain network.
In this embodiment, the consensus nodes are detected based on a PBFT (Practical Byzantine Fault Tolerance) algorithm, and whether malicious nodes exist in the consensus nodes is determined.
S202, when the malicious nodes exist in the common identification nodes of the block chain network, the malicious nodes in the block chain network are reduced to be common nodes or eliminated.
When a malicious node is detected to exist in the consensus node in the block chain network, the malicious node can be marked as an untrusted node and simultaneously becomes a common node; when the malicious node does not exist in the common node in the detection block chain network, the common node in the block chain network is a trusted node, and data common identification can be performed.
And S203, taking the candidate nodes in the block chain network as consensus nodes according to the trust degrees of the candidate nodes in the block chain network.
It should be understood that in the PBFT algorithm, assuming there are n malicious nodes, at least 3n +1 consensus nodes are needed to identify the attack of the malicious nodes. Therefore, in order to ensure that the number of the consensus nodes is larger than 3n +1, optionally, the trust degree of the candidate nodes in the block chain network is detected, and a node with higher trust degree can be selected from the candidate nodes to serve as a new consensus node.
In conclusion, the common identification nodes in the block chain network are detected; when malicious nodes exist in the consensus nodes of the block chain network, the malicious nodes in the block chain network are reduced to common nodes; and taking the candidate nodes in the block chain network as consensus nodes according to the trust degrees of the candidate nodes in the block chain network. Therefore, the consensus nodes in the block chain network are adjusted by adopting a dynamic change mechanism, so that the data consensus of malicious nodes serving as the consensus nodes is avoided, the safety of transaction data is guaranteed, and the credibility of the transaction is guaranteed.
