YOUR NEXT DISCOVERY
One number.
One key.
160 puzzles.
There is mathematics behind every Bitcoin address. Explore the public Bitcoin puzzles and understand what BitBeard is searching for.

Know the range
Each puzzle limits the possible numbers. One level higher means twice as many candidates.
Calculate an address
Each candidate number produces a public key, which is then used to derive a Bitcoin address.
Compare with the target
If the calculated address matches the puzzle target, the matching key has been found.

What do status and balance mean?
“With balance” means there were confirmed, unspent bitcoin at the time of retrieval. “Spent” means funds had been spent and no confirmed balance remained. This does not independently prove that a key was published. Small later deposits are possible. Unconfirmed transactions are excluded.

FROM UNDERSTANDING TO YOUR OWN DEVICE
Your next step:
BitBeard.
Here you learn individual calculation steps. BitBeard turns them into a standalone search with a display and on-device controls. Pro adds pool, cluster and optional FPGA support to suit your setup.
The size of the search range remains decisive. More computing power does not guarantee a match or a return.
