Rollups are structures that have been designed as a way of scaling Ethereum’s capacity to process transactions and data. They group a bunch of tasks and compute them offchain, only posting the result of these transactions to Ethereum, allowing more data to be piled up on L1 (layer one). Ethereum co-founder Vitalik Buterin has been pushing rollups as part of the future of Ethereum scaling since 2020, and with the proposal of Danksharding, its scaling roadmap has become rollup-centric. Rollups and the Scalability Problem Ethereum, one of the first-generation smart contracts-enabled blockchains, has been facing a scalability problem due to its limited capabilities for processing transactions and data. In its base layer, Ethereum can process approximately 15 transactions per second (TPS), which was enough in its first stages but is now insufficient given the popularity of the blockchain. Rollups attack this problem by taking part of the blockchain burden offchain, while maintaining a c
