Long-term impact of MEV-Share, MEVBlocker, and BuilderNet on Ethereum’s market structure

Determine the long-term impact on the market structure of Ethereum’s block building market of the orderflow distribution mechanisms MEV-Share, MEVBlocker, and BuilderNet, which currently rely on trusted entities or are in early development.

Background

The paper highlights emerging systems—MEV-Share, MEVBlocker, and BuilderNet—that aim to distribute private orderflow more fairly and privately, potentially mitigating centralization pressures in the builder market.

Because these systems either rely on trusted components or are not yet mature, their ultimate effects on market structure, including competitiveness and centralization, are not yet established, prompting the need for longitudinal evaluation.
