Layer 2

Architecture

Layer 2 protocols represent a critical scaling solution for blockchain networks, functioning as an overlay to the primary chain to enhance transaction throughput and reduce associated costs. These systems offload transaction processing, batching multiple operations before periodically submitting a summarized state change to Layer 1, thereby mitigating congestion and improving scalability. Different architectural approaches, such as rollups and state channels, offer varying trade-offs between security, complexity, and capital efficiency, impacting their suitability for diverse applications within decentralized finance. The design of a Layer 2 solution directly influences its capacity to support complex financial instruments and high-frequency trading strategies.
