Layer-1 Layer-2

Definition

Layer-1 refers to a base blockchain protocol, such as Bitcoin or Ethereum, which processes and secures transactions directly on its main network. Layer-2 solutions are secondary frameworks built atop these Layer-1 blockchains, designed to improve scalability and transaction speed. These Layer-2 networks, like rollups or sidechains, process transactions off-chain and then periodically settle them back to the main Layer-1. This architectural approach aims to alleviate congestion on the foundational chain.
