summary

Princeton student work in 2014 leads to an Arbitrum prototype, a 2018 uNet/Usenix paper, and a product built on the rollup-centric roadmap; deployed Arbitrum One shows 20x lower cost, about 5x higher gas capacity and ~48x faster block time (0.25s vs 12s). Arbitrum Stylus launches a testnet offering EVM-plus (run Solidity and Rust/C/C++ together) and claims 10–15x faster execution. Layer‑3s cut parent‑chain gas ~300x, trading complexity for lower cost and faster finality.
