Calculations - Why its almost impossible to cheat the Bitcoin system
Imagine a sneaky miner named Max. He buys lots of computers and wants to trick Bitcoin Town. He sends Alice a payment — but secretly, he also starts building a fake blockchain where he sends the money back to himself!
The Race
The network is like a race between honest miners and Max. If honest miners have more power, the chance Max ever catches up shrinks exponentially — it gets smaller and smaller very fast!
Example
If the attacker has only 10% of the networks power:
- After 1 block: 20% chance
- After 3 blocks: 1% chance
- After 6 blocks: ~0% chance
Thats why stores wait for several confirmations before saying: "Payment accepted!"
In short:
- 🧱 Honest miners and attackers race to build chains.
- ⚖️ If honest miners have more power, attackers lose.
- 💸 After a few blocks, payments are irreversible.
- 🔢 Math, not trust, keeps Bitcoin secure!
