Bitcoin Puzzle #71 — a transparent, open-source GPU pool
Pool your GPU with others to search for the ~7.1 BTC Puzzle #71 key. Open source, pay-on-success, live dashboard.
What this isPuzzle #71 is one of the unsolved Bitcoin puzzle addresses —
1PWo3JeB9jrGwfHDNpdGK54CRas7fsVzXU, its private key somewhere in the range 2^70–2^71, ~7.1 BTC sitting on it, still unclaimed. The public key isn't exposed, so the only way in is brute-force range search. This pool splits that keyspace into bands and hands them out to workers — many GPUs cover more ground than one.
From-scratch secp256k1 + hash160 GPU solver, one codebase for CUDA and OpenCL. No altcoin, no token, nothing to buy. You point spare GPU time at it; if the key is ever found, the prize is split among everyone who searched.
Why you can trust it — enforced by the code, not by me- Open source — read every line, confirm there's no backdoor: github.com/lattica-core/puzzle-pool
- Commission only on success — the 1 BTC operator fee applies only if the key is found and verified. Nothing found → nothing taken.
- Independent verification — a "found" report is never trusted; the coordinator re-derives the address from the reported key and matches it to the target itself.
- Live public dashboard — every band handed out, every key checked, live pool hashrate: pool.lattica.org
- Honest odds — this is a long-shot lottery, not income. Almost everyone finds nothing and pays their own electricity. Only bring spare GPU time.
How to join- Windows: download puzzle-pool-v0.1.0-windows-x64.zip, edit run.bat (set your BTC payout address), double-click.
- Linux: download puzzle-pool-v0.1.0-linux-x64.tar.gz, edit run.sh, then ./run.sh (needs an OpenCL driver: sudo apt install ocl-icd-libopencl1).
- Manual:
poolworker --server http://pool.lattica.org:8080 --solver gpu-ocl --payout YOUR_BTC_ADDRESS --name yourname
Use
--solver gpu for CUDA (NVIDIA). You're paid
pro-rata by the number of keys your worker scanned if the key is ever found — so set
--payout to your own BTC address.

doc/RUNNING.mdTL;DR — spare GPU + your BTC address → you scan a slice of Puzzle #71's keyspace. If anyone in the pool hits it, the ~7.1 BTC (minus the 1 BTC commission) is split pro-rata by keys scanned. Fully open source — verify it yourself. It's a long shot; don't spend your rent on electricity.
