实用拜占庭容错共识（practical byzantine fault tolerance, PBFT）算法因主节点随机选举、共识阶段需完成大量签名验证，存在显著的通信与计算开销。针对这一问题，文章提出融合动态信誉评分与BLS聚合签名的改进型共识算法——DB-PBFT(dynamic reputation and BLS-based PBFT)。该算法从准确性、稳定性、活跃度三个维度，对节点行为开展周期性量化评估，以此实现主节点的动态优选与轮换；同时引入BLS(Boneh Lynn Shacham)聚合签名技术，在投票阶段完成签名的批量合并与一次性验证，大幅简化签名验证流程。实验结果表明，改进后的DB-PBFT算法有效降低了系统通信延迟，显著提升了共识效率，且在不同节点规模、高并发交易的场景中均具备良好的适应性。
