⚡ Day 10 — How Crypto Transactions Work
Today you’ll learn what actually happens when you send crypto from one wallet to another.
💡 Step-by-Step (Simplified)
1️⃣ You create a transaction
Example: Send 0.05 $BTC to a friend
You sign it using your private key
2️⃣ Network broadcasts it
Your wallet sends the transaction to thousands of nodes.
3️⃣ Miners/validators verify it
They check:
✔ You have enough balance
✔ Your signature is valid
✔ No double spending
4️⃣ Transaction enters a block
Once verified, it’s grouped with others.
5️⃣ Block gets added to the blockchain
Now the transaction becomes permanent and unchangeable.
6️⃣ Confirmations start
More confirmations = more security.
(Ex: BTC often considered safe after 3–6 confirmations)
🟦 Why Fees (Gas) Exist
You pay a small fee so validators include your transaction in the next block.
Higher fee = faster confirmation.
