Open source client

Install. Run. Win.

The website assigns the work. Your computer decides how to execute it using its locally configured engine and GPU profile.

Puzzle-aware routing keeps Puzzle 71 on the bundled BitCrack and KeyHunt path while preparing puzzles 140, 145, 150, 155 and 160 for an explicitly installed PSCKangaroo executor.

Possible-solution alerts transmit anonymous metadata only. Private keys remain local, and temporary delivery failures retry automatically every 30 seconds.

Security principles

Your discovery belongs to you.

OpenPuzzle coordinates work but never receives a discovered private key.

No registration

Participation is anonymous. Each installation generates only a random local UUID.

Keys remain local

A discovered private key is stored exclusively on the computer that found it.

Blockchain verification

A potential solution creates only a metadata report pending review. A puzzle is marked solved only after independent confirmation through the Bitcoin blockchain.

Local engine configuration

GPU, backend, executable and tuning settings stay under the participant’s control.

Documentation

A small and open protocol.

Clients anonymously claim a range, report non-sensitive progress and confirm when that range has been searched. A potential solution report contains only assignment and anonymous client identifiers. Private keys and raw engine output are never transmitted.
