Hyperliquid L1 vs Sei

Hyperliquid is a performance‑tuned Layer‑1 that employs HyperBFT consensus—an optimised HotStuff variant—to finalise blocks in 400 ms. Its on‑chain order book matches > 100k orders per second without gas, made possible by an in‑memory state machine replicated across 32 validators. Launched in April 2024, the chain settles $4‑6 billion daily volume in perpetual futures and supports CosmWasm smart contracts for third‑party dApps.

Sei is a parallelised Cosmos‑SDK Layer‑1 optimized for order‑book exchanges, using Twin‑Turbo consensus to reach 300–400 ms finality. Its built‑in matching engine lets dApps compose on a shared liquidity layer, and fee markets are denominated in SEI with bulk‑order discounts. The ‘V2’ upgrade adds EVM compatibility via SeiDB and WASM contracts side‑by‑side.
