Formalizing MEV for Blockchain Security Proofs ∞ Research

A transparent blue, possibly resin, housing reveals internal metallic components, including a precision-machined connector and a fine metallic pin extending into the material. This sophisticated assembly suggests a specialized hardware device designed for high-security operations

The image displays smooth, glossy, intertwined abstract forms rendered in a palette of white, light blue, dark blue, and silver, set against a soft grey background. These dynamic, flowing shapes create a sense of interconnectedness and layered complexity

Briefing

This foundational paper introduces a formal theory of Maximal Extractable Value (MEV), addressing the critical gap in established theoretical frameworks for understanding these pervasive economic attacks on public blockchains. It proposes a general, abstract model of blockchain operations and smart contract interactions. This rigorous theoretical basis allows for the development of security proofs against MEV attacks, moving beyond empirical observations to provide a systematic framework for designing more robust and secure blockchain architectures. The theory provides a pathway for protocols to mitigate the detrimental effects of MEV on user experience and network integrity.

$Abstract, intertwined forms dominate the frame, featuring a prominent dark blue, matte, tubular structure. This solid element is intricately interwoven with numerous transparent, highly reflective, fluid-like components that brilliantly refract vibrant blue light against a soft gray background$

Context

Prior to this research, Maximal Extractable Value (MEV) was primarily understood through empirical observation of economic attacks. Adversaries reorder, drop, or insert transactions within blocks to extract value from smart contracts, impacting mainstream DeFi protocols. The prevailing theoretical limitation centered on the absence of a comprehensive, formal model to systematically analyze and quantify these attacks, hindering the development of provably secure countermeasures against such sophisticated economic exploitation.

Analysis

The core idea centers on developing a formal theory of MEV through an abstract model of blockchains and smart contracts. This model precisely defines the mechanisms by which value extraction occurs, encompassing transaction reordering, insertion, and censorship. The research fundamentally differs from previous approaches by shifting from anecdotal evidence and ad-hoc mitigation strategies to a rigorous, mathematical framework. This new primitive establishes the necessary theoretical groundwork for constructing proofs of security, allowing protocol designers to reason about MEV resilience with formal guarantees.

The image displays an abstract composition centered around a dark, irregular mass with glowing blue elements, partially obscured by white, cloud-like material. Transparent rods traverse the scene, intersecting with central forms, surrounded by reflective metallic structures and two distinct spheres

Outlook

This formalization of MEV lays essential groundwork for future research into provably secure blockchain designs. It enables the development of new protocol architectures and transaction ordering mechanisms inherently resistant to economic manipulation. Real-world applications could include more equitable decentralized exchanges, resilient lending platforms, and ultimately, a more predictable and trustworthy on-chain environment for all participants within the next three to five years.

This research establishes the indispensable theoretical bedrock for understanding and actively mitigating Maximal Extractable Value, profoundly influencing the future security and economic stability of decentralized systems.
