Imagine a record book that no one can change, and everyone can verify. That’s blockchain — the backbone of crypto like Bitcoin and Ethereum.
✅ It’s not just about coins. Blockchain is used in:
🔹 Voting
🔹 Healthcare
🔹 Supply chains
🔹 Digital identity
🔹 Smart contracts
🧠 It works like this:
Data is recorded in blocks
Each block links to the next — forming a chain
Once added, data can’t be changed
The system runs without middlemen, using consensus rules (PoW, PoS)
📌 Key Benefits:
🔐 Security
🌍 Transparency
⚡ Speed
💸 No need for banks
Whether you're new to crypto or exploring Web3, understanding blockchain is your first step to real empowerment.
