We present a comprehensive analysis of the implications of artificial latency in the Proposer-Builder Separation framework on the Ethereum network. Focusing on the MEV-Boost auction system, we analyze how strategic latency manipulation affects Maximum Extractable Value yields and network integrity. Our findings reveal both increased profitability for node operators and significant systemic challenges, including heightened network inefficiencies and centralization risks. We empirically validates these insights with a pilot that Chorus One has been operating on Ethereum mainnet. We demonstrate the nuanced effects of latency on bid selection and validator dynamics. Ultimately, this research underscores the need for balanced strategies that optimize Maximum Extractable Value capture while preserving the Ethereum network's decentralization ethos.

翻译：我们对以太坊网络中提议者-构建者分离框架下人为延迟的影响进行了全面分析。聚焦于 MEV-Boost 拍卖系统，我们剖析了策略性延迟操控如何影响最大可提取价值收益与网络完整性。研究结果表明：节点运营商的盈利增加与显著的系统性挑战并存，包括网络效率降低与中心化风险加剧。我们通过 Chorus One 在以太坊主网上运行的试点项目对这些洞见进行了实证验证，揭示了延迟对出价选择及验证者动态的微妙影响。最终，本研究强调了在优化最大可提取价值捕获与维护以太坊网络去中心化精神之间寻求平衡策略的必要性。
