You've probably seen L2 everywhere in crypto. Here's what it actually solves. Ethereum (a Layer 1) processes every transaction directly on its main network. That security is valuable but it means transactions can get slow and expensive when demand is high. A Layer 2 is a separate network built on top of Ethereum. It handles transactions faster and cheaper, then periodically bundles and submits proof of that activity back to Ethereum. Think of it like a busy highway (Ethereum) with a toll booth backup. An L2 is like adding express lanes traffic still eventually reaches the same destination, but moves faster and costs less to get there. The key part L2s still rely on Ethereum for security. They're not separate, disconnected networks they inherit trust from the main chain while offering better speed and lower fees. Not all L2s work the same way some use different methods to prove their transactions are valid, with different tradeoffs in speed, cost, and how quickly funds can move back to Ethereum. $ETH L2s aren't a separate narrative from Ethereum they're an extension of it, built to solve a real scaling problem. Have you used an L2 for a transaction? What was the actual difference in cost or speed for you?
