Introduction to Arbitrum as a Layer 2 Solution
Arbitrum has emerged as a leading Layer 2 scaling solution for Ethereum, designed to address the persistent challenges of network congestion and high gas fees. By leveraging advanced rollup technology, Arbitrum enhances Ethereum's capabilities while maintaining its core security and decentralization principles.
How Arbitrum Works: Optimistic Rollups Explained
- Off-chain transaction processing: Arbitrum processes transactions outside the Ethereum mainnet, bundling them into batches for periodic mainnet verification.
- Optimistic validation: The system assumes transactions are valid by default, only initiating full verification when challenged.
- Reduced mainnet load: This approach decreases Ethereum's congestion by handling most computations off-chain.
