According to international experiences,blacklist policy,as a systematic project,is compatible with law and regulations,social credit system,and social observation movement. This paper reviewed the international experiences in blacklist policies and analyzed the existing problems in blacklist policies. In addition,three constructive suggestions were proposed in this paper.展开更多

文摘针对区块链网络中共识节点的恶意行为导致的区块链系统安全问题,提出一种基于LSTM(long short-term memory)-Blacklist的动态信任度证明机制(PoDT-LSTMB)。该动态信任度证明机制通过前向注意力机制的两层LSTM神经网络学习并分析参与共识节点的行为数据,预测节点行为倾向。以节点信任度为基础构建黑名单,剔除低于信任度阈值的节点,提高全网节点的总体可信性。以正常区块上链率以及节点信任度的变化为主要评估指标,与信任度证明PoT(Proof of Trust)机制以及不带黑名单的PoDT-LSTM机制进行了对比实验。实验结果表明,基于前向注意力机制的两层LSTM神经网络结构准确率可达0.9151,本文提出的PoDT-LSTMB机制比PoT机制的正常区块上链率提高30%~33%。
