Proof of Stake (PoS) is like a lottery where people who own more coins have more tickets. Instead of solving puzzles, you "stake" your coins to help validate transactions and earn rewards!
🎰 How It Works (The Lottery)
Think of it like a raffle at school:
Step 1: Buy Tickets (Stake Coins)
You lock up your coins in the network. Each coin is like one raffle ticket.
Alice stakes 100 coins → 100 tickets
Bob stakes 50 coins → 50 tickets
Charlie stakes 10 coins → 10 tickets
Step 2: Random Selection
The network randomly picks a winner. More tickets = better chances!
Alice has a 62.5% chance, Bob 31.25%, Charlie 6.25%
Step 3: Validate & Earn
The winner validates the new block of transactions and earns rewards!
🔒 What's "Staking" Your Coins?
When you stake coins, you're saying:
"I'll lock up my coins as a promise that I'll be honest. If I cheat, I'll lose them!"
It's like a security deposit. You get it back (plus rewards!) as long as you follow the rules.
