MEV Is Not Eliminated by Design. It Just Moves to a Different Layer.

Jascha Samadi argues that maximal extractable value, or MEV, is not a flaw that certain architectures can simply remove. His core claim is narrower and more structural: wherever a system processes valuable shared state in sequence, ordering itself carries economic value. That value can be auctioned in public, embedded in legal arrangements, hidden inside bilateral relationships, or redirected to a shared pool, but it does not disappear. The article compares four settings. Ethereum turns ordering into an open market through searchers, builders, relays, validators, and order flow auctions. Canton removes the public market around ordering, yet still leaves discretion with sequencers and operators, especially in private deployments where most volume settles today. Traditional finance, Samadi writes, has spent decades packaging the same rent under labels such as payment for order flow, dark pools, and last look, with enforcement records showing how opaque systems can still monetize queue position and informational advantage. Hyperliquid takes a different route by openly auctioning execution priority and burning the proceeds, making the price visible rather than implicit. His conclusion is that the meaningful distinction is not whether MEV exists. The key questions are who controls ordering, whether access is competitive or assigned, whether the rent is observable or hidden, and where the proceeds ultimately go.
