Layer 2
IntermediateLayer 2 refers to secondary frameworks or protocols built on top of Layer 1 blockchains, such as Ethereum, to improve speed and reduce transaction costs. These solutions handle transactions off-chain and report back to the main chain, helping ease network congestion. Layer 2s enhance the speed and efficiency of blockchain networks while maintaining the main chain’s security. Examples include Arbitrum, Optimism, and Polygon. Layer 2s are essential for scaling decentralised applications (dApps) and expanding the adoption of decentralised finance (DeFi).
