✅ **Lesson 94: What Is a Node in Blockchain?** 🖥️🌐
You’ve probably heard the term “node” a lot in the crypto world…
But what *is* a node, really — and why does it matter?
Here’s a simple breakdown 👇

---

🔍 **What’s a Node?**
A node is simply a computer connected to a blockchain network.
It holds a complete copy of the blockchain ledger and plays a key role in verifying and sharing data.
Nodes are what make blockchain decentralized — no single server, just thousands of independent computers working together across the globe.

---

🧠 **What Do Nodes Do?**
✅ Store the entire blockchain
✅ Validate and confirm transactions
✅ Share data with other nodes to keep the network alive
✅ Protect the network from fraud and attacks
Some nodes also mine or stake, depending on the blockchain’s model.

---

🔐 **Why Are Nodes So Important?**
No nodes = no blockchain.
They’re essential for keeping things:
💪 Secure
🧩 In sync
📢 Transparent
🌍 Decentralized

More nodes = stronger network = greater trust.

---

💡 **Think of nodes as the protectors of the blockchain.**
They’re not just watching — they’re powering the entire system.
