What Is Arbitrum (ARB)?
Arbitrum is a Layer 2 (L2) scaling solution for Ethereum, designed to improve speed, scalability, and cost efficiency. It utilizes Optimistic Rollups to enhance transaction throughput while maintaining Ethereum's security benefits. Key advantages include:
- Higher throughput compared to Ethereum
- Lower transaction fees
- Off-chain computation, reducing storage load
The native token, ARB, plays a crucial role in governance. Offchain Labs, Arbitrum’s developer, transitioned to a decentralized autonomous organization (DAO) structure called Arbitrum DAO. ARB holders can vote on proposals affecting protocol upgrades, fund allocation, and security measures.
Arbitrum’s 2023 Roadmap Highlights:
- Launch of Orbit, a Layer 3 solution
- Support for Rust, C++, and other programming languages via Stylus
- Expansion of validator sets for greater decentralization
- Migration of Arbitrum One to Layer 2
On March 16, 2023, Arbitrum announced its ARB airdrop, distributing 12.75% of total supply to early users and DAOs. Eligibility was based on network interaction before March 1, 2023.
Who Founded Arbitrum?
Arbitrum was developed by Offchain Labs, a team specializing in Ethereum scaling solutions.
