Layer 2 Rollup Scaling

Architecture

Layer 2 rollup scaling represents a fundamental shift in blockchain infrastructure, designed to augment the throughput capabilities of base-layer networks like Ethereum. This approach offloads transaction processing from the main chain, bundling multiple transactions into a single proof submitted to Layer 1, thereby reducing congestion and associated costs. Rollups utilize either optimistic or zero-knowledge (ZK) proofs to validate these batched transactions, differing in their fraud-proof mechanisms and computational demands. Consequently, this architectural innovation directly impacts the scalability of decentralized applications and complex financial instruments reliant on blockchain technology.
