Layer2 Solutions

Definition

Layer2 solutions are secondary protocols built on top of existing blockchain networks, such as Ethereum, to improve their scalability and efficiency. These solutions process transactions off the main blockchain, or Layer1, and periodically submit aggregated proofs or summaries back to the main chain. Examples include rollups, state channels, and sidechains, all designed to reduce transaction fees and increase transaction speed. Layer2 technologies are crucial for enabling broader adoption of decentralized applications and digital assets.
