Layer 2 Scaling

Architecture

Layer 2 scaling represents a pivotal architectural shift in blockchain systems, designed to augment the throughput capacity of a base layer—typically a Layer 1 blockchain—without compromising its core security tenets. These solutions offload transaction processing from the main chain, executing it on a secondary framework and periodically settling the results on Layer 1, thereby mitigating congestion and reducing transaction fees. Consequently, this approach facilitates a greater volume of transactions, enhancing the scalability required for broader adoption of decentralized applications and financial instruments. The design choices within Layer 2 architectures directly influence the trade-offs between scalability, security, and decentralization, impacting the overall system performance.
