Briefing
The escalating threat of Maximal Extractable Value (MEV) poses a critical problem for public blockchain integrity, stemming from an underdeveloped theoretical understanding of these economic attacks. This paper introduces a foundational breakthrough ∞ a formal, universal definition of MEV, precisely quantifying the maximum value an adversary can extract regardless of their specific capabilities or resources. This rigorous axiomatization of adversarial knowledge provides a robust framework for assessing MEV-freedom, fundamentally reshaping how blockchain architectures can be designed to resist and mitigate these pervasive economic manipulations, thereby enhancing network fairness and security.

Context
Prior to this research, the pervasive issue of Maximal Extractable Value, encompassing various economic attacks like reordering, dropping, or inserting transactions, lacked a sufficiently established theoretical foundation. While empirical evidence highlighted the significant and detrimental impact of MEV on DeFi protocols and users, the absence of a universal, formal definition hindered comprehensive analysis and the development of robust, provably secure mitigation strategies. This theoretical gap meant that the full scope of adversarial capabilities and potential value extraction remained ill-defined, leaving blockchain systems vulnerable to unquantified risks.

Analysis
The paper’s core mechanism involves the introduction of a formal, universal definition of MEV, which fundamentally redefines how adversarial gains are understood within blockchain contexts. This definition axiomatizes adversarial knowledge, allowing for a precise quantification of the maximal value any adversary can extract by manipulating transaction ordering. This universal framework considers the full spectrum of an adversary’s potential actions and knowledge, leading to a more comprehensive and robust assessment of MEV. The methodology includes a theoretical study of properties such as monotonicity and and applies these principles to demonstrate MEV-freedom in real-world smart contracts, moving beyond ad-hoc observations to provide verifiable security guarantees.

Outlook
This foundational work on universal MEV opens significant new avenues for research and practical application. Future work will likely focus on developing provably MEV-resistant protocol designs and transaction ordering mechanisms, leveraging this formal definition to build more secure and equitable blockchain systems. In the next 3-5 years, this theoretical framework could enable the creation of new tools for real-time MEV monitoring and prevention, leading to more resilient DeFi applications and a fairer transaction environment across various blockchain architectures. It also sets a precedent for applying rigorous formal methods to complex economic phenomena in decentralized systems.

Verdict
This research delivers a decisive theoretical framework for Maximal Extractable Value, fundamentally strengthening the foundational principles of blockchain security by enabling a universal, quantifiable assessment of adversarial economic exploitation.
