🚀 **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
