1/ What is Layer 2 (L2)? Imagine the main blockchain (like Ethereum) as a small coffee shop with one barista. When too many people (transactions) order at once, the line gets long and drinks get pricey (high gas fees). L2 is like adding a second counter outside the shop to serve more people quickly without crowding the main barista!

2/ How does L2 work? L2 takes a bunch of transactions off the main blockchain, handles them separately, and then sends a quick summary back to the main chain. It’s like having a helper who does most of your work and just tells you the important stuff!

3/ Types of L2 Solutions There are a few ways L2 works: Optimistic Rollups: Assumes everything is okay unless someone says it’s not. Like trusting your friend cleaned the kitchen—until you see it’s messy! ZK-Rollups: Uses smart math to prove transactions are correct without sharing all the details. It’s like proving you know a secret without telling it! Plasma: Makes mini blockchains that check in with the main one. Think of it as small teams working together under one big boss!

4/ Why do we need L2? As more people use crypto, blockchains get super crowded—like a road during rush hour. L2 helps make things faster and cheaper while keeping the blockchain safe and fair. It’s key to making crypto easy for everyone to use!
