Briefing

The research addresses the critical problem of Maximal Extractable Value (MEV) fundamentally limiting blockchain scalability, despite advancements in technical throughput. It introduces a foundational breakthrough ∞ a novel MEV auction design integrating programmable privacy via Trusted Execution Environments and explicit bidding. This new theory implies a future blockchain architecture where efficient blockspace utilization is paramount, leading to genuinely lower transaction fees and unlocking new application categories.

A sleek, white, abstract ring-like mechanism is centrally depicted, actively expelling a dense, flowing cluster of blue, faceted geometric shapes. These shapes vary in size and deepness of blue, appearing to emanate from the core of the white structure against a soft, light grey backdrop

Context

Historically, blockchain scaling discussions centered on increasing raw technical throughput through methods like sharding or improved consensus algorithms. The prevailing assumption was that greater blockspace capacity would directly translate to lower fees and enhanced utility. However, this perspective overlooked the complex economic incentives of MEV, particularly the emergence of “spam auctions” where searchers consume newly available blockspace with speculative, wasteful transactions, thereby neutralizing scaling benefits and maintaining elevated transaction costs.

A polished silver-metallic, abstract mechanical structure, resembling a core processing unit, is surrounded by numerous translucent blue spheres. Many of these spheres are interconnected by fine lines, creating a dynamic, lattice-like pattern interacting with the metallic mechanism

Analysis

The paper’s core mechanism proposes a two-pronged approach to reclaim blockspace efficiency. First, “programmable privacy” leverages Trusted Execution Environments (TEEs) to grant MEV searchers real-time visibility into transaction flows. This allows searchers to discover arbitrage opportunities off-chain without the ability to frontrun or sandwich users, thus eliminating the need for wasteful on-chain probing.

Second, “explicit bidding” replaces the current inefficient “spam auction,” where competition is proxied by raw gas consumption, with a direct monetary auction for precise transaction inclusion and ordering rights. This fundamentally differs from previous approaches by directly addressing the economic incentives that drive blockspace congestion, transforming MEV extraction from a parasitic activity into a transparent, value-capturing mechanism.

This visual metaphor represents the foundational elements of blockchain technology and crypto networks

Outlook

Future research will explore the inherent trade-offs of explicit auctions, specifically the minimum block times imposed by networking latency and computational requirements. The real-world application of this theory could unlock truly scalable blockchains with consistently low fees within 3-5 years, fostering novel use cases such as on-chain social networks and agentic micropayments. This framework opens new avenues for academic inquiry into market design for decentralized systems, emphasizing economic efficiency over raw technical capacity.
