Explore a groundbreaking conference talk on SPEEDEX, a novel decentralized exchange (DEX) designed for secure asset trading without centralized control. Discover how this innovative system achieves high throughput of over 200,000 transactions per second on 48-core servers, even with tens of millions of open offers. Learn about SPEEDEX's unique features, including its ability to run entirely within a Layer-1 blockchain, elimination of internal arbitrage opportunities, and prevention of certain front-running attacks. Understand the key design insight of using an Arrow-Debreu exchange market structure and the algorithm that computes asset valuations while preserving financial correctness constraints. Gain insights into how SPEEDEX's market structure ensures fairness across trades and enables efficient parallelization of trade operations. Hear from Stanford University researchers Geoffrey Ramseyer, Ashish Goel, and David Mazières as they present their prototype implementation within the Stellar blockchain ecosystem.
