⚡ Mining Bitcoin Like a Real Miner
Discover how computational work secures the Bitcoin network

Proof of Work is the original consensus mechanism that powers Bitcoin. It's a computational puzzle that miners must solve to add new blocks to the blockchain.
🎯 The Core Idea
Imagine you need to find a special number that, when combined with your block data and hashed, produces a hash starting with several zeros. The only way to find it? Trial and error.
🎮 Try Mining Yourself
Click "Start Mining" to search for a valid nonce. Watch as the miner tests different numbers until finding one that produces a hash starting with zeros.
Security Through Work
To attack the network, you'd need to redo all this computational work faster than all honest miners combined - virtually impossible.
Energy Investment
Mining requires real electricity. This physical cost makes attacks expensive and ensures miners have "skin in the game".
Fair Competition
Every miner has an equal chance per hash attempt. No shortcuts exist - it's pure computational lottery.
Block Rewards
Miners who find valid blocks earn cryptocurrency rewards. This incentivizes honest participation in network security.
💡 Real-World Analogy
Think of proof of work like a lottery where you can buy as many tickets as you want, but each ticket costs electricity:
- Each hash attempt = One lottery ticket
- More computing power = More tickets per second
- Finding valid nonce = Winning the lottery
- Block reward = Lottery prize (6.25 BTC for Bitcoin)
The key difference: in mining, you can't just buy tickets with money - you must spend energy and time computing hashes.
