WTF is MEV? Pre-Confs & MEV Commit Explained

MEV is how some VCs value Layer 1 blockchains, its how "sandwich attacks" happen onchain, and its sometimes toxic.

Although, we've found that "toxic flow" is really just profitable user trading onchain...that's a conversation for another day though.

MEV has evolved from its early days as "Miner Extractable Value," a term that felt relevant in a proof-of-work world, to "Maximal Extractable Value," a crucial component embedded within Ethereum’s economic fabric. As block production on Ethereum became centralized—a trade-off to support a decentralized validator set—the discussion has shifted towards ensuring that this centralization doesn’t compromise the core decentralized ethos.

This is where things get a bit spicy.

In today's pod with Murat from Primev, we discuss the ability for users to receive pre-confs for their transactions, ensuring not just their inclusion in a block but also their execution (this is the big discrepancy).

We first met Murat at Modular Summit with Tarun Chitra, where we learned about MEV commit on an iPad whiteboard diagram.

We’re also seeing a broader discussion unfold around the idea of multiple concurrent proposers, a proposal that could further decentralize block proposal power and potentially reduce censorship. Primev’s MEV Commit fits neatly into this narrative by building on top of existing infrastructure like MEV Boost, without requiring drastic changes, and offering additional layers of security and efficiency.

Testnet results are already showing promise, with MEV Commit adding up to 10% more value to blocks, which translates to higher rewards for validators and, ultimately, a more secure network. MEV Commit is reshaping how we think about gas markets, private order flow, and the overall efficiency of the Ethereum network.

Pretty technical pod, hope you enjoy!
