Arbitrum is a Layer 2 blockchain that scales Ethereum by using optimistic rollups, allowing faster and cheaper transactions by executing them off-chain and only posting minimal transaction data to Ethereum. Its primary purpose is to maintain Ethereum’s decentralization and security while optimizing for high throughput. Arbitrum supports the migration of Ethereum dApps without major code changes.
