ETH rollups like Optimism and Arbitrum are different from Matic in the sense that they are layer-2 scaling solutions for Ethereum that allow for increased transaction throughput and improved scalability. Unlike Matic, which is a sidechain, ETH rollups use a combination of off-chain computation and on-chain data availability to process transactions. This allows them to process transactions more quickly and with lower fees than Matic, while still maintaining the security of the Ethereum blockchain. Additionally, since they are built on the Ethereum blockchain, they are able to take advantage of the existing infrastructure and tools available on the Ethereum network. This makes them a great option for projects that require scalability and quick transaction processing.
