Why Mining Matters

Unpredictable Hashes

Changing the nonce reshuffles the hash output. You cannot predict which nonce will work, so miners must try many values.

Difficulty Controls

The target requires more leading zeros at higher difficulty. This makes successful hashes rarer and block time longer.

Competition + Rewards

Miners race to find the first valid hash. The winner earns a block reward, aligning incentives with securing the network.

Education Notice

This simulator is for learning only. It simplifies cryptography and does not produce real cryptocurrency.
