summary

SPEEDEX implements an Arrow-Debreu exchange market inside a Layer‑1 blockchain, computing unique per-block asset valuations so all trades use the same exchange rates and commute. The prototype runs on 48‑core servers and achieves 200,000 transactions per second even with tens of millions of open offers, eliminates cyclic arbitrage and many front‑running attacks, and is integrated as a minimal Layer-1 blockchain patch (Stellar) that preserves financial correctness.
