Layer-2 Rollups are scaling solutions designed to increase the transaction throughput and reduce fees on a main blockchain, known as Layer-1. They process transactions off-chain, bundle them together, and then submit a single, compressed proof of these transactions back to the Layer-1 chain. Their function is to alleviate network congestion and improve efficiency without compromising the security of the underlying blockchain. This technology is vital for enhancing the usability of decentralized applications.
Context
Layer-2 Rollups are a major focus in cryptocurrency news, particularly concerning the scalability of networks like Ethereum. The current state involves significant development and deployment of various rollup types, such as optimistic and zero-knowledge rollups, each with distinct security and efficiency trade-offs. A critical future development will be the increasing interoperability between different Layer-2 solutions and their seamless integration into decentralized applications, aiming to create a highly scalable and user-friendly blockchain ecosystem.
