Briefing

The paper addresses the critical absence of a formal theoretical framework for Maximal Extractable Value (MEV) attacks, which exploit transaction ordering on public blockchains. It introduces a comprehensive, abstract model of blockchains and smart contracts to establish a foundational MEV theory. This breakthrough provides the necessary rigorous basis for developing and proving the security of future blockchain architectures against sophisticated economic manipulations, ensuring more robust and predictable decentralized systems.

Context

Before this research, the understanding of MEV largely stemmed from empirical observations of economic attacks on DeFi protocols. The prevailing theoretical limitation involved the absence of a unified, formal model capable of precisely defining and analyzing the complex interplay of transaction ordering, smart contract interactions, and adversarial value extraction. This gap hindered the systematic development of provably secure countermeasures.

Analysis

The core mechanism involves constructing a general, abstract model that formalizes the components of a blockchain and its smart contract execution environment. This model defines adversarial capabilities related to transaction reordering, inclusion, and censorship, allowing for a precise characterization of MEV. The approach fundamentally differs from prior work by moving beyond empirical analysis and ad-hoc countermeasures, instead providing a foundational mathematical language for MEV phenomena. This theoretical framework enables the rigorous derivation of security properties and the design of mechanisms provably resilient to MEV.
