Bitcoin Mining Demo
Experience proof-of-work mining firsthand. Adjust the block header fields and mine for a valid hash. Watch how difficulty affects the time and computational effort required.

How It Works
Bitcoin mining is the process of finding a nonce value that, when combined with the block header data, produces a hash that meets the network's difficulty requirement (starts with a certain number of zeros).
- • The block header contains metadata about the block
- • Miners increment the nonce and hash the header repeatedly
- • Higher difficulty means more leading zeros required
- • The first miner to find a valid hash wins the block reward
