L2 Scalability

Architecture

Layer-2 scalability solutions represent a fundamental shift in cryptocurrency network design, addressing throughput limitations inherent in base-layer blockchains. These architectures offload transaction processing from the main chain, enabling higher transaction volumes and reduced fees without compromising security. Rollups, state channels, and sidechains exemplify common approaches, each employing distinct mechanisms for data availability and consensus. Effective implementation necessitates careful consideration of trade-offs between decentralization, security, and scalability, impacting the overall system resilience and user experience.
