What Is Arbitrum (ARB)?
Arbitrum is a Layer 2 (L2) scaling solution for Ethereum, designed to enhance speed, scalability, and cost efficiency while leveraging Ethereum's security and compatibility. By utilizing optimistic rollups, Arbitrum processes most computations and storage off-chain, enabling higher throughput and lower fees compared to Ethereum's mainnet.
ARB is the native token of Arbitrum, primarily used for decentralized governance. Offchain Labs, Arbitrum's developer, transitioned to a Decentralized Autonomous Organization (DAO)—Arbitrum DAO—where ARB holders vote on protocol upgrades, fund allocation, and elect a Security Council.
Key Developments (2023):
- Launch of Orbit, a proprietary Layer 3 solution.
- Support for multiple programming languages (Rust, C++) via Stylus.
- Expansion of validators to include independent institutional participants.
- Migration of Arbitrum One to a full L2 solution.

FAQ Section
Q1: How does Arbitrum differ from Optimism?
A: Both use optimistic rollups, but Arbitrum’s fraud proofs are multi-round, reducing gas costs.
Q2: Is ARB used for staking?
A: No, ARB is a governance token. Validators are permissioned in the current phase.
Q3: Can I bridge assets to Arbitrum?
A: Yes, via the official Arbitrum bridge or third-party tools like Hop Protocol.
Q4: What’s Arbitrum Nitro?
A: A major upgrade improving compatibility and reducing fees further.
