Abritrum’s Layer 2 solution uses blockchain rollups to achieve efficient transaction processing. Rollups use a 2-layer architecture to process transactions off-chain before settling them on-chain. The benefit is that the blockchain no longer needs to validate separate transactions – it can directly confirm a “rolled up” batch of transactions.

This scaling solution differs from other Layer 2s, such as sidechains, since rollups typically derive their security from the main blockchain.

Arbitrum’s scaling solution uses a particular type of roll-up called optimistic rollups.
