Arbitrum

Arbitrum is a type of technology known as an optimistic rollup. It allows Ethereum smart contracts to scale by passing messages between smart contracts on the Ethereum main chain and those on the Arbitrum second layer chain. Much of the transaction processing is completed on the second layer and the results of this are recorded on the main chain — drastically improving speed and efficiency.
