Open distributed research

Find Bitcoin with one command.

OpenPuzzle coordinates Bitcoin Puzzle ranges between anonymous clients. Computation and private keys remain entirely on each participant’s machine.

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.

Ubuntu / Linux

Version 1.0.53 · x86_64

Stable release

Vanity now uses blocking CUDA synchronization to release host CPU while waiting for GPU work. The exact candidate passed known-address tests on five RTX 3080 cards and a 30-second simultaneous local measurement. Search kernels, saved profiles, one-hour ranges and common controls are preserved.

Download 1.0.53 for Ubuntu
SHA-256 checksums Release notesSource code

Before you start: install your GPU driver

NVIDIA · CUDANVIDIA driver for your GPU ↗
A driver compatible with the included CUDA engine is required.

AMD · OpenCLAMD driver with OpenCL support ↗
Confirm support with the local engine self-test.

Prebuilt Windows package: no Visual Studio or full CUDA Toolkit / AMD SDK required. Development SDKs are for building from source. AMD Windows hardware validation is still pending.

Windows installation and first run
  1. Download and run the Windows installer .exe. Follow the graphical setup.
  2. Open OpenPuzzle Test - Auto Benchmark from the Desktop, or OpenPuzzle Test in the new Start Menu folder. Normal startup opens only the interface.
  3. For your first profile, choose CPU, CUDA or OpenCL and the device under Tools, then click Benchmark. Review and confirm the local measurement. GPU parameters are automatic; allow about 10–20 minutes for CUDA/OpenCL.
  4. A successful benchmark saves and selects the profile. Start the search explicitly when ready.

The coordinator is automatic. The public package includes no personal profiles or client data. Finish a previous search with Safe Stop before starting another search on the same GPU.

NVIDIA power and fan controls are included; AMD controls are not enabled in this Windows build. Automatic benchmarks were confirmed on Windows 10 and 11. Setup 0.1.5 was reviewed on Windows 11; clean-machine compatibility remains under testing.

Verify the Windows download

Compare the installer with the published Setup 0.1.5 SHA-256 checksums.

OpenPuzzle 1.0.53

Vanity now uses blocking CUDA synchronization to release host CPU while waiting for GPU work. The exact candidate passed known-address tests on five RTX 3080 cards and a 30-second simultaneous local measurement. Search kernels, saved profiles, one-hour ranges and common controls are preserved.

Compiled targets include sm_50 through sm_90 and compute_50 PTX. Other GPU families are not all hardware-validated.

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.
