Layer Two Solutions

Architecture

Layer Two solutions represent a fundamental shift in cryptocurrency network design, addressing scalability limitations inherent in base-layer blockchains. These systems operate ‘off-chain’, processing transactions independently to reduce congestion and associated fees on the primary network, subsequently settling results on the main chain. Different architectural approaches, such as state channels, sidechains, and rollups, each offer unique trade-offs regarding security, decentralization, and throughput, impacting their suitability for specific applications within decentralized finance. The selection of a particular architecture is driven by the need to balance transaction costs with the desired level of security and operational complexity.
