What Is Arbitrum?
Arbitrum has emerged as a leading Ethereum Layer 2 scaling solution, gaining significant traction even before its March 2023 airdrop. As a purpose-built protocol to enhance Ethereum's transaction throughput, Arbitrum combines optimistic rollups with Ethereum's security while maintaining decentralization.
Developed by Offchain Labs and launched in 2021, Arbitrum enables seamless migration of dApps from Ethereum Layer 1 to its Layer 2 environment. The protocol introduced its native governance token, ARB, in March 2023, further solidifying its role in the crypto ecosystem.
Key Features:
- Processes transactions 85x faster than Ethereum's base layer (15-30 TPS → 2,550+ TPS potential)
- Uses batch processing for efficient off-chain computation
- Maintains Ethereum-level security via fraud proofs
- Fully EVM-compatible for developer convenience
The Arbitrum Team
Arbitrum's development is led by Princeton University researchers:
- Ed Felten: Computer science professor specializing in blockchain scalability
- Steven Goldfeder (PhD) & Harry Kalodner (PhD): Cryptographic systems experts
This technically proficient team ensures continuous innovation in Arbitrum's infrastructure.

How Arbitrum Works: Optimistic Rollups Explained
Arbitrum's core innovation lies in its optimistic rollup architecture:
- Bundling: Transactions are aggregated off-chain
- Compression: Data is condensed into smaller batches
- Submission: Batches are periodically committed to Ethereum
- Dispute Window: 7-day challenge period for fraud proofs
This process resembles shopping with a full cart (batch processing) versus buying items individually (Ethereum's base layer).
Transaction Lifecycle:
| Stage | Duration | Description |
|---|---|---|
| Execution | Instant | Transactions process off-chain |
| Finality | ~1 min | Initial batch confirmation |
| Full Security | 7 days | Fraud-proof window closes |

Frequently Asked Questions
What makes Arbitrum different from Optimism?
While both use optimistic rollups, Arbitrum employs multi-round fraud proofs for higher efficiency versus Optimism's single-round system.
Can ARB tokens be used to pay gas fees?
No. Ethereum (ETH) remains the gas currency. ARB is strictly for governance.
How secure is Arbitrum?
It inherits Ethereum's security via:
- Cryptographic fraud proofs
- 7-day challenge periods
- Decentralized validator set
When will more ARB tokens enter circulation?
Team/investor tokens unlock gradually until 2027 following predetermined vesting schedules.
