About the Project
Arbitrum is an optimistic rollup technology that allows Ethereum smart contracts to scale by passing messages between smart contracts on the Ethereum main chain and a second layer chain. Most transaction processing is completed on the second layer, with results recorded on the main chain, which drastically improves speed and efficiency. The project includes two main chains: Arbitrum One (built on rollup technology) and Arbitrum Nova (using AnyTrust technology), which developers use to build user-friendly decentralized apps.
