Layer 2 Scaling Efficiency
Layer 2 scaling efficiency refers to the ability of secondary protocols to increase transaction throughput and reduce costs by processing activity off the main blockchain while maintaining its security. These solutions, such as rollups or state channels, aggregate multiple transactions before submitting a proof to the main chain.
This drastically lowers the cost per transaction and allows for faster settlement, which is critical for derivatives trading. The efficiency of a Layer 2 solution is measured by its latency, throughput, and the security of its bridge to the main layer.
As the demand for complex financial applications grows, the efficiency of these scaling layers becomes a major determinant of a protocol's competitiveness. It is the bridge between theoretical scalability and practical usability.
