摘要
提出了一种基于信用模型的共识协议。首先，该共识协议借鉴了个人信用风险评估的思想，设计了一种基于BP神经网络的节点信用度模型。其次，构造了一种分片轮转模型，它可以根据节点的信用度高低分割搜索空间产生新区块，同时对协议所面临的可能攻击进行分析，修复了协议存在的漏洞。最后，仿真实验表明共识协议既能有效地降低新区块产生过程中重复计算的巨大资源消耗，也能抑制大型矿池的产生，使整个区块链系统变得更加安全可靠。
Abstract
A consensus protocol based on the credit model was proposed.Firstly
the consensus agreement drew on the idea of personal credit risk assessment and a node credit model based on BP neural network was designed.Secondly
a piecewise rotation model was also constructed to segment the search space according to the node’s credit level to generate new blocks.At the same time
the possible attack of the protocol was analyzed and the vulnerability of this protocol was fixed.Finally
the simulation experiments show that the protocol not only effectively reduces the huge resource consumption in the process of new block generation
but also suppresses the generation of the large mine pool
making the whole blockchain system more secure and reliable.
