“…The specific evaluation of the master node's health score is shown in formula (3), where H i ðtÞ is the health score value of the t th round of consensus and k is the threshold of the consensus round. If the master node does not send messages to the candidate node in time during the view process, resulting in no new block being generated, its health score will drop.…”

“…Exploring blockchain-based energydistributed transactions can help reduce grid dispatch costs and increase transaction transparency. According to the degree of decentralization, blockchain is divided into three modes: public blockchain [2], consortium blockchain [3], and private blockchain [4]. The multicenter characteristics of consortium blockchain are more suitable for the status quo of power reform in China.…”

In order to reduce the cost of grid dispatching and increase the transparency of energy transactions, the distributed energy transaction model based on blockchain is constructed. At the same time, in order to improve the high communication overhead and low throughput of the traditional PBFT algorithm in the consortium blockchain, an efficient Byzantine fault-tolerant consensus mechanism (DE-BFT) for the energy blockchain is designed. The algorithm improves from two aspect: node election and main chain consensus. In the stage of node election, the model uses a health score evaluation and a verifiable random function to improve the security and randomness of node selection. In the stage of main chain consensus, the efficient data consistency interaction protocol decreases the complexity of the communications between nodes, down to a constant term level from exponential one. The result shows that, compared with other consensus algorithm, the DE-BFT algorithm performs better in terms of consensus delay, communication overhead, throughput, and consensus node reliability.
