Gate News 消息，3月14日，剑桥替代金融研究中心发布比特币网络物理基础设施韧性纵向研究，覆盖11年点对点网络数据及68起经核实的海底电缆故障事件。研究显示，全球72%至92%的跨国海底电缆需同时失效，比特币网络才会出现显著节点断连。基于每场景1000次蒙特卡洛模拟，87%以上的真实故障事件对节点影响低于5%，电缆故障与比特币价格相关系数接近于零（-0.02）。研究同时揭示随机故障与定向攻击之间的显著不对称性：若攻击者针对关键枢纽电缆，破坏阈值将骤降至20%；若定向攻击节点数量最多的五大托管服务商——Hetzner、OVH、Comcast、Amazon及Google Cloud，仅需移除5%的路由容量即可造成同等冲击。
