[0020] The present invention will be further clarified below in conjunction with the drawings and specific embodiments.
[0021] The present invention provides a Byzantine Fault Tolerant Consortium Chain Consensus Method (CBFT) for the protection of electricity consumption information, which includes the following steps:
[0022] 1) Based on the BP neural network to build a blockchain node credit evaluation model, the node with the highest credit is selected as the master node through the blockchain node credit evaluation model:
[0023] The original PBFT algorithm adopts the method of electing the master node in turn. This method causes the view replacement after the malicious master node is elected, which causes the system performance to be greatly reduced. In this step, the master node election method is changed to solve this problem. A type of multi-layer neural network based on error back propagation algorithm can flexibly model sample data and reveal the implicit non-linear rel...
