Layer 2 Efficiency

Definition

Layer 2 efficiency refers to the speed and cost-effectiveness of operations on scaling solutions built atop main blockchains. This concept measures how effectively Layer 2 protocols, such as rollups or sidechains, process transactions and execute smart contracts, aiming to alleviate congestion and high fees on the underlying Layer 1 network. High Layer 2 efficiency means faster transaction finality, significantly reduced costs, and greater throughput, making decentralized applications more accessible and scalable for widespread use. It directly addresses the limitations of base layer blockchains.
