Arbitrum is a Layer 2 scaling solution for Ethereum, which aims to provide faster and cheaper transactions while still maintaining the security and decentralization of the Ethereum network. It achieves this by using a system of smart contracts and off-chain computations that are then settled on the Ethereum mainnet.
