Briefing

This paper addresses the critical problem of Maximal Extractable Value (MEV) within public blockchains, where adversaries exploit transaction ordering to extract value from smart contracts, leading to significant user and network detriments. It proposes a novel formal theory of MEV, grounded in a general, abstract model of blockchain and smart contract interactions, thereby establishing a rigorous framework for understanding and analyzing these economic attacks. The most important implication of this new theoretical framework is its capacity to serve as a robust foundation for developing provable security measures against various forms of MEV manipulation, ultimately fostering more equitable and resilient decentralized systems.

This scene visually represents the core of a digital asset or a key data point within a decentralized system, perhaps akin to a seed phrase or a critical smart contract parameter

Context

Prior to this research, the pervasive issue of Maximal Extractable Value, characterized by block producers’ ability to profit from transaction reordering, insertion, or censorship, lacked a sufficiently established theoretical foundation. While empirical evidence highlighted the detrimental impact of MEV on DeFi protocols and user experience, a comprehensive, abstract model capable of systematically analyzing these economic attacks and serving as a basis for formal security proofs remained an unsolved foundational problem in blockchain theory. The absence of such a framework hindered the development of robust, provably secure mitigation strategies.

Analysis

The paper’s core mechanism introduces a formal theory of MEV by constructing a general, abstract model of blockchain and smart contract operations. This model conceptually separates the underlying blockchain state from the sequence of transactions, allowing for a precise definition of value extraction independent of specific protocol implementations. It fundamentally differs from previous, more ad-hoc analyses by providing a universal language to describe MEV, enabling researchers to reason about its properties and potential vulnerabilities across diverse blockchain architectures. This new primitive allows for the systematic identification and classification of MEV opportunities, moving beyond anecdotal observations to a rigorous, mathematical understanding of how and why value is extracted.

Outlook

This foundational work opens new avenues for research into provably secure blockchain designs and MEV-resistant protocols. In the next 3-5 years, this theoretical basis could lead to the development of novel transaction ordering mechanisms, improved consensus algorithms, and smart contract designs that inherently minimize or eliminate adversarial value extraction. Potential real-world applications include more equitable decentralized exchanges, resilient lending protocols, and blockchain architectures that offer stronger guarantees of transaction fairness and censorship resistance, thereby enhancing the overall integrity and trustworthiness of decentralized finance.
