Abstract

Aiming at the problems of low consensus efficiency and insufficient incentive mechanism existing in current consensus algorithms, this paper proposed an alliance chain consensus algorithm based on credit. Firstly, according to the behavior of nodes participating in the consensus process, it designed a node credit evaluation mechanism, and solved the problem of insufficient incentive mechanism between nodes through credit rewards. Secondly, it constructed a credit blockchain and credit calculation model, stored the credit value of the node, and used it as the basis for selecting "miner" nodes, which improved the efficiency of the consensus algorithm. Finally, this paper proposed a round-by-round miner node selection algorithm, which used random algorithm and priority ranking algorithm to select miner nodes in turn, and proposed a node credit evaluation method to avoid excessive credit value of nodes and became "oligarchs" and ensured that the fairness of the nodes becoming miners. The experimental simulation results show that the credit consensus algorithm has low computational power consumption, fast block production speed, better performance than the existing consensus algorithm, and can be well applied to the business and medical alliance chain scenarios.
