Briefing

Maximal Extractable Value (MEV) presents a critical challenge to public blockchains, where transaction manipulation allows adversaries to extract value, yet a robust theoretical understanding has been lacking. This research establishes a formal theory of MEV by introducing a general, abstract model of blockchains and smart contracts, which precisely defines adversarial behaviors in transaction ordering. The most significant implication of this new theoretical framework is its capacity to underpin rigorous security proofs, enabling the design of provably secure blockchain architectures inherently resistant to MEV attacks.

Context

Prior to this seminal work, Maximal Extractable Value was primarily understood through empirical observations and informal analyses, lacking a rigorous theoretical underpinning. This prevailing limitation meant that the ability to formally analyze MEV and develop provably secure countermeasures against these sophisticated economic attacks was severely constrained, posing a significant challenge to the long-term integrity and fairness of public blockchain networks.

Analysis

The paper’s core conceptual breakthrough is the development of a comprehensive, abstract model that formalizes Maximal Extractable Value. This new theoretical primitive rigorously defines how adversaries manipulate the sequencing, inclusion, or exclusion of transactions within blocks to extract value from smart contracts. This approach fundamentally differs from prior empirical observations by providing a precise mathematical framework, enabling a systematic analysis of MEV rather than relying solely on anecdotal evidence. This abstract representation allows for the exact characterization of MEV vulnerabilities and facilitates the design of provably verifiable mitigation strategies.
