AI总结:
本研究提出一种基于区块链的社交媒体网络协议BE-SMN,将错误信息传播建模为区块链双花攻击并结合改进的SIR模型,经多社区网络数值实验验证,其在拉平错误信息感染人数曲线方面效果优于基线网络。
摘要:
本文开发了一种用于社交媒体网络的区块链协议BE-SMN(支持区块链的社交媒体网络),以缓解错误信息的传播。BE-SMN基于信息传输时间分布推导而来,通过将错误信息传播建模为区块链上的双花攻击实现。随后将错误信息分布纳入SIR(易感、感染、恢复)模型,替代了传统SIR模型中的单一速率参数。接着在多社区网络上对错误信息传播进行数值研究,结果表明所提出的支持区块链的社交媒体网络在拉平感染人数曲线方面优于基线网络。
英文摘要:
The paper develops a blockchain protocol for a social media network (BE-SMN) to mitigate the spread of misinformation. BE-SMN is derived based on the information transmission-time distribution by modeling the misinformation transmission as double-spend attacks on blockchain. The misinformation distribution is then incorporated into the SIR (Susceptible, Infectious, or Recovered) model, which substitutes the single rate parameter in the traditional SIR model. Then, on a multi-community network, we study the propagation of misinformation numerically and show that the proposed blockchain enabled social media network outperforms the baseline network in flattening the curve of the infected population.
