DUAL FLOW BATCH AUCTION

Summary from the TLDR Crypto newsletter

The Dual Flow Batch Auction (DFBA) is a novel market structure that addresses critical flaws in blockchain-based Continuous Limit Order Books, including MEV exploitation, latency arbitrage, and adverse flow that drive up trading costs. The system separates orders into maker and taker groups, conducting two independent auctions every ~100ms where makers compete purely on price rather than speed, eliminating time-priority advantages and allowing market makers to quote tighter spreads with reduced exposure to toxic flow. DFBA provides uniform pricing within each auction (all participants fill at the same clearing price) while maintaining efficient liquidity provision, with analysis suggesting auction intervals of 100ms-1s are optimal for natural flow traders who see negligible benefit from lower latencies. This design represents a fundamental shift away from speed-based competition toward fair pricing mechanisms that better serve actual trading needs rather than optimizing for bots and block producers.
