Arbitrum is a Ethereum Layer-2 scaling solutions developed by Offchain Labs, designed to improve transaction speed, lower fees, and expand the capabilities of decentralized applications while inheriting Ethereum’s security. Its flagship chain, Arbitrum One, implements an Optimistic Rollup protocol, processing transactions off-chain and posting compressed data batches to Ethereum, enabling high throughput with trustless fraud-proof verification. The Arbitrum Nova chain uses the AnyTrust protocol, relying on a Data Availability Committee to deliver ultra-low-cost transactions for gaming, social apps, and high-volume use cases. Developers can also deploy custom Arbitrum Orbit chains (Layer-3) that interoperate seamlessly within the ecosystem. Powered by the Nitro tech stack, Arbitrum offers full EVM equivalence, advanced calldata compression, and support for multiple programming languages via Stylus (WASM smart contracts).
