⚡ Why FastScan_Puzzle71(.exe) is different:
BitCrack and CUDACyclone need hours of setup — CUDA Toolkit, Makefile fights, dependency hell. They often fail to compile entirely. FastScan_Puzzle71(.exe) works in 30 seconds: download, run one command, start mining. No compilation, no errors, zero frustration.
🎯 But here's the truth:
Even with the fastest GPU, mining alone gives you virtually zero chance to find the key. That's not opinion — that's math. With over a decade working on elliptic curve cryptography, I can tell you: the only realistic path is a pool. SatoshiPool gives you a real, fair share of the reward — without needing a datacenter.
⚡ FastScan GPU v2.0 (5.2 GH/s) is no longer updated – it is kept only as a reference.
All active development and pool binaries are based on the 5.2 GH/s production code.
Uses X‑only pubkey comparison – no SHA256/RIPEMD in hot path. With GLV endomorphism (×3) and point negation (×2), one point addition gives 6 independent key candidates.
| Implementation | Speed (RTX 4090) | Setup | Notes |
|---|---|---|---|
| fastscan_253_256 current | 50 GH/s | click & run | production, split‑key, live pool |
50 billion keys per second is possible because GLV endomorphism (×3) and point negation (×2) turn every single point addition into 6 independent key candidates — no hashing in the hot path, just pure elliptic‑curve math.
The engine is already running live at wallet.satoshipool.org — every connected miner contributes to the same split‑key round, and every hit unlocks real Satoshi‑era wallets with 50+ BTC each.
🧠 Engineering, not magic.
The 50+ GH/s speed comes from combining known mathematical techniques (GLV, negation, batch inversion) with system‑level optimisations (X‑only lookup, 24‑bit prefix index, L1/L2 bitmaps, persistent multi‑GPU scheduling).
None of these are new in isolation. What is new – and what makes this the fastest public tool for 253‑256 pubkey scanning – is the way they are integrated into a single, stable, production‑ready binary that runs on any CUDA GPU from GTX 9xx to RTX 50xx.

If you can't compile the binaries yourself and want to join the pool, download everything directly from our GitHub: github.com/ethicbrudhack/FastscanGPU-BitcoinPuzzleChallengeBreaker-
This database is for use with the standalone independent code (not pool).
💡 Tip: Download ALL files from GitHub. For Puzzle #71: put Gtable in one folder. For Wallets 253-256: put pubkeys.bin + gtableX.bin + gtableY.bin in one folder with the worker. DLLs are shared between both. Then just run the pool command and it works!

You can test if the binaries work by running them directly on any known Bitcoin address. Just make sure you know the exact bit range of that address.

Example 2 (Linux - fastscan_253_256) | 253-256 pubkey test — key found in round 8
✅ Expected result: [EN] FOUND 1 HIT(S)!
→ IT WORKS! You can test any binary from our GitHub with any address - just need the correct bit range.

pubkeys.bin). Custom .bin = ignored hits.Understanding the Bitcoin Puzzle mining process.
There are ~244.85 trillion chunks in Bitcoin Puzzle 71. Each chunk(segment) contains ~4 821 742 milion private keys. The goal is to find which range(chunk) contains the correct private key. The finder receives 40% reward bonus + your regular share.
In parallel, we also scan forgotten Satoshi‑era wallets (253‑256 bits) – a database of 1,515,486+ early mining addresses from 2009‑2013. Instead of hashing, our engine compares raw public keys directly, reaching 50+ GH/s on modern GPUs. Each found wallet can hold 50+ BTC.
Download the pool worker and binary for your GPU. Run the connection command to start scanning ranges. Each scanned range is your chance to find the private key.
The 7.1 BTC reward is hidden in the 70–71 bit range. Each range is split into 5-million-key chunks. An RTX 3070 crunches over 500 of these chunks per second—each chunk costs practically nothing (far less than a penny for thousands of them). For roughly $5 in electricity, you can scan over 270 million unique chunks. Running your own GPU costs pennies per hour, making cloud rental look wildly expensive. The pool uses mathematically disjoint segments—no two workers ever scan the same key.
When the server assembles the full private key from your submitted share (d), the key is never exposed publicly. The operator uses a private blockchain settlement layer to manually distribute the reward to the winning miner's registered Bitcoin address. This ensures that the public key is never revealed, preventing anyone from intercepting or stealing the reward before it reaches you. All payouts are processed manually by the operator to guarantee security and fairness.Reward distribution is simple: The finder gets a 40% bonus. The remaining 55% is shared among all miners (including the finder) based on their contribution. The operator takes 5% to keep the pool running. This ensures everyone is rewarded fairly.
No email required. None of your data is stored. Join the pool anonymously. All passwords are encrypted server-side. The pool uses 100% open-source client and proof-of-work (PoW).
Joining and using the pool is free. The pool only knows solved puzzle information. Unsolved puzzles and correct private keys remain unknown to everyone until found.
While Puzzle 71 targets one specific address, the 253‑256 campaign searches for real, forgotten mining wallets from 2009–2013.
Between 2009 and 2013, early Bitcoin miners accumulated thousands of wallets that have since been forgotten — lost hard drives, discarded backups, abandoned mining operations. These wallets sit untouched, holding balances that were worth pennies at the time but are worth tens of thousands of dollars today.
The database behind this search contains 1.5M+ unique public keys extracted from on-chain data — every address that mined a block or received coins during the Satoshi era and has remained untouched since. Each entry is a real wallet with a real balance, not a puzzle or a trap.
Unlike Puzzle 71 where there is exactly one winner, the 253‑256 campaign offers thousands of potential hits — and the pool searches all of them simultaneously. Every scanned key is checked against every database entry in a single pass, meaning your GPU works for all wallets at once, not one at a time.
🛠️ Built by an engineer, for engineers.
SatoshiPool is not a weekend project. It combines battle‑tested cryptography (VanitySearch, secp256k1) with novel system‑level optimisations (X‑only lookup, persistent multi‑GPU scheduling, split‑key with DEDUP) – all wrapped in a single binary that works out of the box.
No compilation, no dependency. "works on every GPU card!". Just download, run, and mine.
