Briefing
This paper addresses the insufficiently established theoretical foundations of Maximal Extractable Value (MEV), a pervasive class of economic attacks impacting public blockchains. It proposes a formal theory of MEV, grounded in a general, abstract model of blockchains and smart contracts. This foundational breakthrough provides a rigorous basis for developing proofs of security against MEV attacks, significantly advancing the understanding and resilience of future blockchain architectures.

Context
Before this research, Maximal Extractable Value (MEV) represented a critical, yet theoretically underexplored, vulnerability within public blockchains. Adversaries, capable of reordering, dropping, or inserting transactions, could extract substantial value from smart contracts, leading to detrimental effects on users and network integrity. Existing empirical observations highlighted the scale of the problem, but a comprehensive, formal theoretical framework to systematically analyze and counter these attacks was absent.

Analysis
The core idea introduces a formal theory of MEV, conceptualized within an abstract model of blockchains and smart contracts. This framework precisely defines MEV as value extracted by adversaries through transaction manipulation, such as reordering or insertion. It fundamentally differs from previous approaches by providing a mathematical and logical foundation for MEV, enabling the formal derivation of security properties and the systematic analysis of adversarial behaviors. The model serves as a universal language for discussing and proving MEV resistance in various protocol designs.

Outlook
This foundational theory opens new avenues for rigorous analysis and design in blockchain security. Future research can leverage this formal model to develop provably secure protocols and mechanism designs that inherently mitigate MEV. Real-world applications could include the creation of MEV-resistant decentralized finance (DeFi) protocols and more robust transaction ordering mechanisms, ultimately fostering a fairer and more predictable on-chain environment for users.

Verdict
This research provides an indispensable theoretical bedrock for understanding and ultimately mitigating the systemic economic vulnerabilities introduced by Maximal Extractable Value in blockchain systems.
