Layer 2 Order Book

Architecture

Layer 2 order books represent a fundamental shift in cryptocurrency exchange design, addressing scalability limitations inherent in on-chain order matching. These systems operate on a separate protocol layered above the main blockchain, enabling faster transaction processing and reduced congestion. Consequently, they facilitate more complex trading strategies and higher throughput, crucial for institutional participation and sophisticated derivatives markets. The underlying architecture often employs state channels or rollups to aggregate transactions before settling them on Layer 1, optimizing gas costs and enhancing overall network efficiency.
