Layer-2

Definition ∞ Layer-2 solutions are secondary frameworks built upon a primary blockchain, often referred to as Layer-1. These systems process transactions off the main chain to increase throughput and decrease fees. They rely on the security guarantees of the underlying Layer-1 network.
Context ∞ The proliferation of Layer-2 technologies is a primary driver in scaling blockchain networks, particularly Ethereum. Current discussions focus on the competitive landscape of various L2 scaling solutions, their respective strengths in terms of security and transaction finality, and their integration with existing decentralized applications. Advances in L2 technology are closely watched for their impact on network usability and adoption rates.
