Cambridge research puts 31% of Ethereum node activity in the US, where a third offline can stall finalization
Concentration of Ethereum validator nodes in the U.S. on centralized cloud providers poses jurisdictional and counterparty risks that could stall network finalization.
THE BLOCK: Cambridge's Alexander Neumüller finds Ethereum nodes clustered on Hetzner, AWS and OVH, with 31% of node activity in the U.S. More than one-third of validators going offline simultaneously could stop checkpoints from finalizing, he says. The SEC argued for U.S. jurisdiction over Ethereum

剑桥大学替代金融中心最新研究显示，美国承载近三分之一的以太坊节点活动，欧盟（不含英国）约占 39%，节点分布整体以欧美地区为主，但未集中于单一国家；节点主要托管于 Hetzner、AWS 和 OVH 等云服务商。研究负责人 Alexander Neumuller 表示，若超过三分之一验证者同时离线，以太坊检查点将停止最终确认；网络应保持地理分散，客户端软件集中同样存在风险，主导客户端出现漏洞可能影响整个网络。此外，研究重新评估了以太坊合并后的能耗，估算当前年耗电量约为 7.9 GWh，较合并前下降约 99.98%，可持续能源使用占比超过 56%。（The Block）wublock123.co
