After the Merge, the MEV landscape is grappling with an unexpected development— the integration of CeFi and DeFi searchers and builders.. A few powerful entities act like mafia getting access to each layer down the stack, posing substantial risks to Ethereum and users' funds. The question looming is whether we are inexorably progressing towards a MEV dystopia.
In this episode, Stephanie (@stephaniiee_ho) achieves a milestone in her journey of MEV exploration with Danning (@sui414), a data scientist from Flashbots, who works at the forefront of MEV observation and analysis. They have a deep dive into the most crucial topics in MEV, commencing with an introduction to the components of the MEV supply chain. The conversation unravels the intricate dynamics between the two sophisticated roles, searchers and builders. Danning sheds light on Order Flow Auctions (OFAs), elucidating the distinction in efficiency and privacy setting between the two most significant OFAs. The discourse also touches on the increasing trend of transactions traversing private mempools.
The conversation further delves into a pressing concern—the emergence of CeFi-DeFi searcher-builder integration as a potent centralizing force within Ethereum, making the MEV dystopia so tangible. Danning provides a comprehensive list of available tools and a user-friendly guide on how to navigate and mitigate the risks of MEV attacks.
