OpenPuzzle coordinates distributed Bitcoin Puzzle range searches. Clients claim work from a central service, run supported search engines locally and report progress back without duplicating assigned ranges.
CPU & GPU
Designed to support CPU and GPU workers with compatible search engines.
Engine integration
Works with GPU-oriented BitCrack workflows and CPU-oriented KeyHunt workflows.
Progress tracking
Workers report progress, speed and completion to the central service.
Fair scheduling
Every client has the same right to receive work. Performance only sizes future ranges; it never changes priority.
Adaptive calibration
Version 1.0.14 learns conservatively from sustained speeds after confirmed successful GPU assignments without changing stable launch settings.
Free, open source and ready to run
