Layer-2 Rollups

Definition

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.
