Briefing

Maximal Extractable Value (MEV) represents a class of economic attacks where network adversaries manipulate transaction ordering to extract value from smart contracts. This paper addresses the insufficient theoretical foundations of MEV by proposing a formal theory grounded in a general, abstract model of blockchains and smart contracts. This foundational breakthrough provides a robust framework for developing provably secure protocols against MEV, enhancing the economic robustness and fairness of decentralized systems.

Context

Prior to this research, the understanding of Maximal Extractable Value largely stemmed from empirical observations of economic attacks within decentralized finance. While the practical impact of MEV was evident, a comprehensive, formal theoretical framework to systematically analyze and counter these complex adversarial behaviors remained underdeveloped. This gap created challenges for rigorously proving security properties and designing effective mitigation strategies.

Analysis

The core of this work is the development of a formal theory of MEV. This theory employs a general, abstract model of blockchains and smart contracts, allowing for a precise characterization of the mechanisms through which value is extracted. The model explicitly defines the adversarial capabilities, such as reordering, dropping, or inserting transactions, enabling a systematic analysis of their impact. This approach fundamentally differs from purely empirical studies by providing a mathematical basis for understanding MEV, moving beyond anecdotal evidence to formal proofs.

Outlook

This formal theory of MEV opens critical avenues for future research, particularly in designing and formally verifying MEV-resistant blockchain protocols and smart contracts. The abstract model provides a powerful tool for analyzing the security implications of various transaction ordering mechanisms and consensus algorithms. Real-world applications could include the development of provably fair transaction inclusion policies and the creation of DeFi protocols inherently resilient to front-running and sandwich attacks, fostering a more equitable on-chain environment.
