摘要
为有效提升业务数据跨级可信协作服务的可扩展性、高鲁棒性、高并发能力与处理效能,提出一种面向多层级大规模节点组网场景的高效共识算法——高效拜占庭容错(Efficient Byzantine Fault Tolerance, EBFT)。在现有共识算法的基础上,把轮换主节点作为常规共识流程的一部分,实现所有节点轮流担任主节点进行提案,以减轻单一主节点带来的压力并保证节点间的公平性。通过合并视图切换流程和正常流程实现了快速共识,进一步提升算法灵活性、可靠性和数字签名性能。仿真实验表明,所提算法满足了跨级大规模业务数据流转对业务系统处理能力和响应速度的实际需求。
In order to effectively improve the scalability,robustness,concurrency and processing efficiency of cross-level trusted collaboration services for data,an efficient consensus algorithm called Efficient Byzantine Fault Tolerance(EBFT)is proposed for multi-level large-scale node networking scenarios.On the basis of consensus algorithm,the rotation of master nodes is taken as part of the regular consensus process.All nodes take turns to serve as master node to make proposals,so as to reduce the pressure of having a single master node and ensure the fairness between the nodes.Additionally,fast consensus is achieved by merging the view switching process and the normal process,which further improves the flexibility,reliability and digital signature performance of the algorithm.Simulation experiments demonstrate that the proposed algorithm meets the actual requirements of cross-level large-scale service data flow for the processing capacity and response speed of information system.
