Purpose-built, exchange-grade Layer‑1 blockchain optimized for on‑chain order books, margining, and custody with trading and settlement as first‑class primitives. Delivers sub‑second finality and high throughput via a pipelined two‑round BFT (DracoBFT), deterministic execution, modular side‑consensus loops, and a change‑log hash commitment; Engine‑API compatibility and trustless proof ingestion connect to EVM and real‑world rails.
