Ethereum, the world’s second-largest blockchain network, persistently grappling with scalability issues due to its popularity and increased network congestion, has had the concept of Layer 2 chains in mind since 2014. As more users and decentralized applications (dApps) were released, transaction costs skyrocketed, and processing times slowed significantly. To address these challenges, developers explored various scaling solutions to optimize Layer 2s, with Ethereum rollups emerging as one of the most promising approaches.
What are Ethereum Rollups?
An Ethereum rollup is a Layer 2 scaling solution that processes multiple transactions off the main Ethereum blockchain (Layer 1), bundles them into a single transaction, and then submits this bundled transaction back to the main chain. By moving the bulk of transaction processing off-chain, rollups can significantly increase the throughput of the Ethereum network while reducing gas fees for users.
Rollups are designed to maintain the secu
