What is Arbitrum (ARB)? A Comprehensive Guide

What is Layer 2 (L2) Blockchain?

A Layer 2 (L2) blockchain is a secondary protocol built atop an existing blockchain (Layer 1) to address scalability, speed, and high transaction costs. By processing transactions off-chain while leveraging Layer 1’s security, L2 solutions like Arbitrum enhance efficiency without compromising decentralization.

What is Arbitrum (ARB)?

Arbitrum is a leading Ethereum Layer 2 scaling solution designed to boost scalability and reduce costs for decentralized applications (dApps) and smart contracts. Its native token, ARB, facilitates network operations, including transaction fees, governance, and staking.

Key features:

• Optimistic Rollups: Processes transactions off-chain, batches them, and submits proofs to Ethereum.
• EVM-Compatible: Supports Ethereum’s tooling and smart contracts.
• Low Fees: Dramatically reduces gas costs compared to Ethereum Layer 1.

Arbitrum’s Technology: L2, PoS, or PoW?

• Layer 2 (L2): Arbitrum operates as an L2 rollup, relying on Ethereum’s security.
• Consensus: Uses Optimistic Rollups, assuming transaction validity unless disputed. Post-Ethereum 2.0, it inherits Ethereum’s Proof of Stake (PoS) security.

ARB Token Utility

The ARB token powers the Arbitrum ecosystem through:

1. Transaction Fees: Pay for network usage.
2. Governance: Vote on protocol upgrades and parameters.
3. Staking: Secure the network and earn rewards.

Who Founded Arbitrum?

Arbitrum was developed by Offchain Labs, co-founded by:

• Ed Felten (Princeton professor, former U.S. Deputy CTO).
• Steven Goldfeder (Princeton researcher).
• Harry Kalodner (privacy-tech expert).

Arbitrum’s Roadmap (2024)

Key Developments:

1. Orbit (L3 Solution): Further scalability with layer-three rollups.
2. Cross-Chain Interoperability: Facilitate asset transfers between Ethereum, Bitcoin, and others.
3. Developer Support: Multi-language smart contract deployment.
4. Community Initiatives: Trading competitions, ARB airdrops, and prediction markets.
