Briefing

This Flashbots research posits that Maximal Extractable Value (MEV) has become the dominant limiting factor for blockchain scalability, as wasteful on-chain searching by MEV bots consumes a substantial portion of network capacity. The paper introduces a novel MEV auction design that combines programmable privacy with explicit bidding mechanisms to address this systemic inefficiency. This new theoretical framework aims to eliminate spam, unlock the full benefits of scaling through lower and more stable fees, and enable the creation of new application types that require abundant and inexpensive blockspace.

White, textured, cloud-like formations are positioned around and partially on top of the blue object, with one larger mass on the right and smaller ones on the left

Context

Prior to this research, the prevailing challenge in blockchain scaling often focused on increasing raw technical throughput through methods like sharding or rollup optimizations. However, these efforts encountered a persistent economic limitation ∞ the “verifier’s dilemma” in a broader sense, where rational MEV searchers blindly probe for opportunities within private mempools. This led to a “spam auction” environment, characterized by inefficient gas consumption and concentrated market power, ultimately neutralizing the gains from technical scaling and artificially inflating transaction fees for users.

Analysis

The core mechanism proposed involves a two-pronged approach ∞ programmable privacy and explicit bidding. Programmable privacy grants searchers real-time visibility into transaction flow, enforcing strict, verifiable restrictions that permit only backrunning while preventing frontrunning, sandwiching, or private data leakage. This enables searchers to perform conditional execution logic off-chain, drastically reducing wasteful on-chain computation.

Concurrently, explicit bidding establishes a direct, price-based mechanism for searchers to bid for specific transaction inclusion and ordering rights, replacing the inefficient gas-based competition. This system aims to align searcher incentives with network efficiency, capturing the true value of MEV without inducing congestion.

Outlook

This research opens new avenues for blockchain architecture by reframing scalability through an economic lens, emphasizing efficient blockspace utilization over raw throughput increases. The implementation of programmable privacy via TEEs and explicit MEV auctions promises to unlock genuinely low and stable transaction fees, fostering a fertile ground for novel applications in decentralized finance, social networks, and agentic micropayments. Future research will likely explore the practical deployment challenges and the long-term game-theoretic implications of these advanced MEV mitigation strategies.
