summary

Arbitrum launches publicly in August 2021 and quickly hits an unexpected $1.6 billion TVL surge within 24 hours, proving the design works at scale. The stack evolves from Nitro to Stylus allows Rust C C++ contracts and Orbit for customizable, Ethereum‑secured rollup chains. Sequencing is currently centralized (run by Offchain Labs, governed and upgradable only via the Arbitrum DAO) with ~10 validators and ongoing work on distributed sequencing. A new protocol, Bold enables permissionless fraud proofs, aims to let anyone validate while keeping one‑honest‑party security.
