Briefing

Maximal Extractable Value (MEV) has emerged as the primary constraint on blockchain scalability, with inefficient on-chain searching consuming significant network capacity. This research from Flashbots introduces a novel MEV auction design to address this economic congestion. The proposed mechanism replaces gas-based bidding with a two-part system, incorporating programmable privacy for searchers. This theoretical shift aims to reallocate network resources, fostering a more efficient and equitable distribution of value across the ecosystem.

The device features a small digital display showing the number '18' alongside a circular icon, emphasizing its operational status

Context

Prior to this research, the prevailing approach to blockchain scaling primarily focused on technical throughput enhancements, such as database sharding and Layer-2 rollups. Despite these advancements, economic congestion persisted, driven by the competitive “spam auction” market structure of MEV extraction. This resulted in a significant portion of newly added blockspace being consumed by speculative bot activity, diminishing the practical benefits for end-users and increasing transaction costs.

Analysis

The core innovation involves a redesigned MEV auction, moving beyond the current gas-based bidding system. This new mechanism grants searchers programmable privacy, allowing them to submit explicit, off-chain bids for transaction ordering. Trusted-execution environments play a crucial role, revealing user flows without enabling frontrunning.

This architecture channels the extracted value back to validators and users, establishing a more transparent and fair market for transaction inclusion. The design fundamentally alters the economic incentives within block production.
