What Is Arbitrum (ARB)?
Arbitrum is a Layer 2 (L2) scaling solution for Ethereum, designed to enhance speed, scalability, and cost-efficiency. It leverages Optimistic Rollups to reduce computational load by processing transactions off-chain while maintaining Ethereum’s security and compatibility.
Key benefits of Arbitrum include:
- Lower fees compared to Ethereum’s mainnet.
- Higher throughput for faster transactions.
- EVM compatibility, enabling seamless deployment of Ethereum-based applications.
The native token, ARB, powers the Arbitrum DAO, a decentralized governance system where holders vote on protocol upgrades, fund allocation, and security measures.
2023 Roadmap Highlights:
- Arbitrum Orbit: A dedicated Layer 3 solution.
- Stylus Integration: Supports developers using Rust, C++, and other languages.
- Decentralized Validation: Expansion to include institutional validators.
- Arbitrum One: Migration to a fully decentralized L2 framework.
On March 16, 2023, Arbitrum announced its ARB airdrop, distributing 12.75% of the total token supply to early users and DAOs. Eligibility was based on network interaction before the March 1, 2023 snapshot.
