What Is Rollup?
A rollup is a specific type of Layer 2 scaling solution that bundles (rolls up) multiple transactions into one batch submitted to the main chain. Optimistic Rollups (Optimism, Arbitrum) and ZK-Rollups (zkSync, StarkNet) are the two main types. Rollups significantly reduce gas costs, making them attractive for large whale transactions where gas savings scale with transaction size.
