Layer 2 Execution Environments

Architecture

Layer 2 Execution Environments represent a fundamental shift in scaling cryptocurrency networks, addressing limitations inherent in Layer 1 consensus mechanisms. These environments, often employing state channels, rollups, or validium, facilitate transaction processing off-chain, thereby increasing throughput and reducing associated costs. The design of these systems necessitates careful consideration of security trade-offs, particularly concerning data availability and fraud proofs, impacting the overall trust model. Effective architecture balances scalability with the core tenets of decentralization and censorship resistance, crucial for maintaining network integrity.
