⚡ Layer 2 in Crypto: The Future of Speed & Scalability

In crypto, time is money. Slow networks like Ethereum can’t keep up with global demand — and that’s where Layer 2 steps in 🚀

🧱 What is Layer 2?

Layer 2 = A secondary blockchain built on top of a Layer 1 like Ethereum.

It handles most transactions off-chain, then settles them securely on Layer 1.

👉 Result? Ultra-fast speed & super-low fees.
