Arbitrum is an Ethereum Layer 2 scaling solution, not a standalone public blockchain. Its governance token, ARB, empowers holders to participate in the Arbitrum DAO, enabling proposal submissions, voting, and fund allocation decisions. This guide explores Arbitrum’s technical framework, ARB token utilities, ecosystem growth, and future prospects.
Arbitrum’s Technical Architecture and Positioning
Developed by Offchain Labs, Arbitrum leverages Optimistic Rollup technology to process transactions off-chain before bundling them for Ethereum mainnet settlement. Key features include:
- Fraud Proofs: Validators challenge suspicious transactions via interactive verification games, ensuring security with just one honest participant.
- High Throughput: Handles ~40,000 TPS (vs. Ethereum’s ~15 TPS) with fees ~90% lower than mainnet.
- EVM Compatibility: Supports seamless migration of Ethereum dApps without code modifications.
