Layer-2 is a secondary structure built upon a base, layer-1 blockchain. Developers leverage layer-2 solutions to increase throughput by remote-sourcing operations from the layer-1 blockchain. Layer-2 solutions are often created by third parties and complete processes independently of the layer-1 blockchain. Because of this separation, developers often refer to layer-2 solutions as “off-chain.” However, layer-2 systems are reliant on the layer-1 blockchain’s security and decentralization. Q: What is Layer-2 in Blockchain? A: refers to a secondary framework or protocol that is built on top of an existing blockchain system.
