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 validate these insights with a pilot that Chorus One has been operating on Ethereum mainnet.
