Arbitrum vs Hyperliquid L1

Arbitrum One and Nova are optimistic rollups using Nitro fraud proofs that compress transactions into calldata submitted to Ethereum. The Orbit toolkit lets projects deploy their own Arbitrum Orbit chains with configurable permissions. ARB token governance manages the 3 000‑plus validator whitelist and a 1 billion‑dollar ecosystem grant fund.

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.
