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：我们针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，节点运营商的盈利能力提升与显著的系统性挑战并存，包括网络效率降低和中心化风险加剧。我们通过Chorus One在以太坊主网上运行的试点项目实证验证了这些见解，揭示了延迟对出价选择和验证者动态的微妙影响。最终，本研究强调亟需制定平衡策略，在优化最大可提取价值捕获的同时，维护以太坊网络的去中心化精神。
