The Arbitrum (ARB) network is a Layer 2 scaling solution for Ethereum designed to address scalability issues and high transaction fees. Developed by Offchain Labs, Arbitrum utilizes Optimistic Rollups to process transactions off-chain before bundling them into periodic summaries submitted to the Ethereum mainnet. This approach reduces costs, increases throughput, and maintains Ethereum’s security.
Key Features of Arbitrum Network
1. Scalability
Arbitrum’s Optimistic Rollups enable off-chain transaction processing, significantly boosting Ethereum’s capacity. This results in:
- Faster confirmation times.
- Lower gas fees.
- Enhanced user experience.
2. EVM Compatibility
Arbitrum supports Ethereum Virtual Machine (EVM) bytecode, allowing seamless deployment of Solidity/Vyper smart contracts without code modifications.
3. Decentralized Finance (DeFi) Integration
Popular DeFi platforms like Uniswap leverage Arbitrum for:
- Decentralized exchanges (DEXs).
- Lending protocols.
- Cross-chain interoperability.
4. Security
Fraud proofs and Ethereum mainnet settlements ensure robust security against invalid transactions.
