🚀 **Crypto News Flash: Layer-2 Blockchains Explained!** 🚀

🔹 **What is Layer-2?**

Layer-2 (L2) blockchains are built on top of Layer-1 (L1) to boost performance and scalability. They tackle high fees and slow transactions of L1, especially during peak usage.

🔹 **Key Differences:**

- **Layer-1:** Handles consensus and transaction settlements (e.g., Bitcoin, Ethereum).

- **Layer-2:** Enhances L1 with rollups, sidechains, and state channels for faster, cheaper transactions.

🔹 **Top Layer-2 Blockchains:**

1. **Polygon (POL)**

2. **Optimism (OP)**

3. **Arbitrum (ARB)**

🔹 **Benefits:**

- Scalability

- Lower transaction costs

- Faster transactions

🔹 **Challenges:**

- Security dependencies

- Complexity and adoption

- Interoperability issues
