🔥 Day 2 — Blockchain in 60 Seconds
Yesterday we learned what crypto is.
Today: How does it actually work?
Welcome to the blockchain — the technology behind every crypto.
💡 What Is Blockchain?
A blockchain is a digital public record where every transaction is stored in “blocks” and linked like a chain.
Think of it as:
📘 A book
📄 Each page = a block
🔗 All pages connected = the chain
🧾 Everyone can see the book = transparency
🟦 Why Is Blockchain Special?
✔ Cannot be changed (very hard to hack)
✔ No single owner (decentralized)
✔ Transparent (anyone can verify transactions)
✔ Secure (math + cryptography protect it)
🟨 Simple Example:
You send 1 $BTC to someone →
The transaction is:
1️⃣ Broadcast to the network
2️⃣ Verified by computers (nodes/miners)
3️⃣ Added to the next block
4️⃣ Forever stored in the blockchain
No bank. No approval.
Just code + consensus + transparency.
