Briefing
Maximal Extractable Value (MEV) presents a critical, yet theoretically underexplored, vulnerability in public blockchains, where adversaries exploit transaction ordering to extract value. This research introduces a foundational formal theory of MEV, grounded in an abstract model of blockchains and smart contracts, to precisely define and quantify this adversarial gain. The most significant implication is the establishment of a rigorous framework for developing provable security against MEV attacks, which is essential for designing more resilient and equitable decentralized architectures.
Context
Prior to this research, Maximal Extractable Value (MEV) was primarily understood through empirical observations and specific protocol analyses, lacking a comprehensive and abstract theoretical foundation. The prevailing challenge involved the absence of a generalized model capable of uniformly characterizing and quantifying the maximal value extractable by adversaries across varied smart contract interactions and blockchain designs. This theoretical void impeded the development of universal security proofs and robust, systemic mitigation strategies against these economic exploits.
Analysis
The paper’s core mechanism is the introduction of a formal, abstract model that universally defines Maximal Extractable Value (MEV) within any blockchain and smart contract system. This model precisely characterizes adversarial capabilities, including the power to reorder, drop, or insert transactions, and quantifies the maximal economic gain achievable by such adversaries. It provides a protocol-agnostic, mathematical framework for deriving universal security proofs against a broad spectrum of MEV attacks, moving beyond ad-hoc or empirical observations.

Outlook
This foundational work opens several critical avenues for future research and real-world application. Immediate next steps involve applying this formal MEV theory to rigorously analyze the security of existing decentralized finance protocols, identifying specific vulnerabilities and informing the design of provably MEV-resistant systems. In the next three to five years, this theoretical framework could enable the development of blockchain architectures with inherent MEV-security guarantees, leading to fairer transaction ordering, more robust consensus mechanisms, and a significant reduction in economic exploits. Furthermore, it paves the way for integrating MEV analysis into automated formal verification tools, enhancing the overall security posture of the blockchain ecosystem.
Verdict
This research establishes the indispensable theoretical bedrock for understanding and mitigating Maximal Extractable Value, fundamentally advancing the foundational principles of blockchain security and economic fairness.
