Formal MEV Theory for Blockchain Security Analysis ∞ Research

Two futuristic robotic components, featuring sleek white exterior panels and transparent sections revealing intricate blue glowing circuitry, are shown connecting at a central metallic joint against a dark background. The illuminated internal mechanisms suggest active data processing and secure operational status within a complex digital system

A vibrant blue, metallic, cylindrical mechanism forms the central focus, partially enveloped by a dynamic cascade of numerous small, translucent, spherical particles. The particles appear to be in motion, some clinging to the blue surface, others flowing around it, creating a sense of intricate interaction and processing

Briefing

This paper addresses the critical absence of a formal theoretical framework for Maximal Extractable Value (MEV) in public blockchains, a phenomenon empirically known for its detrimental impact on decentralized finance (DeFi) protocols and user experience. It introduces a comprehensive, abstract model of blockchains and smart contracts to establish a foundational theory of MEV. This theoretical groundwork provides the necessary basis for developing rigorous proofs of security against various MEV attacks, thereby advancing the integrity and stability of future blockchain architectures.

Context

Prior to this research, Maximal Extractable Value manifested as a significant, empirically observed problem within public blockchain networks, particularly impacting DeFi. The prevailing theoretical limitation centered on the lack of a formal, abstract model to systematically define and analyze MEV. This absence hindered the development of provably secure countermeasures against transaction reordering, insertion, and exclusion attacks, leaving blockchain systems vulnerable to economic exploitation.

Analysis

The core idea involves constructing a formal theory of MEV by developing a general, abstract model of blockchains and smart contracts. This model provides a precise language for describing the interactions between block producers and transaction orderings, allowing for the systematic identification and quantification of value extraction opportunities. It fundamentally differs from previous empirical observations by offering a foundational, mathematical framework. This new primitive establishes a rigorous basis for analyzing the economic attacks that define MEV, enabling the design of security mechanisms with verifiable guarantees.

Outlook

This research establishes a critical foundation for the systematic analysis and mitigation of MEV, a pervasive challenge in decentralized systems. The formal theory opens new avenues for designing provably secure consensus algorithms and transaction ordering mechanisms, leading to more equitable and robust blockchain ecosystems. Its potential real-world applications include the development of MEV-resistant Layer 2 solutions and novel auction designs for block space, enhancing overall network fairness and security within the next three to five years.

This foundational work provides the indispensable theoretical rigor required to understand, quantify, and ultimately counteract Maximal Extractable Value, profoundly strengthening the security principles of blockchain technology.
