Hyperliquid is a high-performance blockchain platform secured by HyperBFT, a variant of HotStuff consensus. It features a fully decentralized architecture with HyperCore for margin and matching engine state, and HyperEVM for general-purpose execution. The platform achieves exceptional performance with median end-to-end latency of 0.2 seconds (99th percentile 0.9 seconds) and throughput of approximately 200,000 orders per second on mainnet. This low-latency design enables users to port automated trading strategies with minimal changes and provides instant feedback through the UI, while its consensus algorithm and networking stack can potentially scale to millions of orders per second.
