Briefing

This foundational research addresses the inadequately established theoretical underpinnings of Maximal Extractable Value (MEV) attacks, a pervasive class of economic exploitations within public blockchains. It introduces a formal theory of MEV, constructing a general, abstract model of blockchains and smart contracts. This theoretical framework provides the essential basis for developing rigorous proofs of security against MEV attacks, directly impacting the design of future blockchain architectures for enhanced resilience and fairness.

The composition highlights sharp hexagonal modules, some emitting a bright blue light, set against a dark, blurred background, creating a sense of depth and advanced technology

Context

Prior to this work, the understanding of Maximal Extractable Value (MEV) largely stemmed from empirical observations of economic attacks, where adversaries manipulate transaction ordering to extract value. The field lacked a comprehensive, formal theoretical framework to systematically analyze and counter these sophisticated attack vectors. This presented a significant academic challenge, as a precise theoretical model is critical for designing provably secure and robust decentralized systems.

Analysis

The core idea presented is a formal theory of MEV, built upon a general and abstract model of blockchains and smart contracts. This model allows for the precise definition and analysis of MEV, moving beyond anecdotal evidence to a rigorous, mathematical understanding of how value extraction occurs. The theory identifies the specific conditions under which adversaries, possessing the ability to reorder, drop, or insert transactions, can exploit smart contracts. This foundational abstraction enables the systematic derivation of security proofs, offering a clear framework for identifying and mitigating MEV vulnerabilities within blockchain protocols.

Outlook

This formalization of MEV provides a critical intellectual scaffolding for the next generation of blockchain protocol design. It enables the development of new, provably secure mechanisms that actively deter or eliminate value extraction opportunities. Future research will leverage this theoretical basis to engineer more resilient decentralized finance (DeFi) applications and fundamentally reshape the economic security landscape of blockchain networks. The rigorous framework paves the way for advanced mitigation strategies and fairer transaction ordering protocols.
