+# Bitcoin Keyhunt Tool
+
+---
+
+* `keyhunt.py` is a Bitcoin puzzle key-search engine for CPU. For each integer `k` in a range it treats `k` as a secp256k1 private key, derives the compressed P2PKH address, and compares its HASH160 directly against a target address (decoded once, outside the hot loop). It uses `coincurve` (libsecp256k1) for fast EC math, supports checkpoint/resume, and can shard a range across multiple machines/processes.
+
+* **Honest feasibility note:** this is about as fast as CPU Python gets, but CPU brute force cannot solve large puzzles — puzzle #71 alone is 2^70 keys. Its real uses are proving your pipeline is correct against already-solved puzzles, benchmarking, and learning.
+
+---
+
+# Commands:
+
+    git clone https://github.com/demining/CryptoDeepTools.git
+
+    cd CryptoDeepTools/31BitcoinKeyhuntTool/
+
+    pip3 install -r requirements.txt
+
+Verify the pipeline against solved puzzles:
+
+    python3 keyhunt.py --selftest
+
+Benchmark keys/sec on this machine:
+
+    python3 keyhunt.py --benchmark
+
+Search a range for a target address (example: solved puzzle #20):
+
+    python3 keyhunt.py --address 1HsMJxNiV7TLxmoF6uJNkydxPFDog4NQum --start 0x80000 --end 0xfffff
+
+Resume with a checkpoint file:
+
+    python3 keyhunt.py --address 1HsMJxNiV7TLxmoF6uJNkydxPFDog4NQum --start 0x80000 --end 0xfffff --checkpoint progress.json
+
+Split a range across shards (e.g. shard 0 of 4):
+
+    python3 keyhunt.py --address <addr> --start 0x... --end 0x... --shards 4 --shard-id 0

+"""
+keyhunt.py — Bitcoin puzzle key-search engine (educational / benchmark tool)
+
+What it does:
+  For each integer k in a range, treats k as a secp256k1 private key,
+  derives the compressed P2PKH address, and compares to a target.
+
+  private key k  ->  P = k*G  ->  compressed pubkey  ->  SHA256 -> RIPEMD160
+                 ->  (that hash160 is compared directly to the target's hash160)
+
+Speed notes:
+  - Uses coincurve (libsecp256k1) for EC math — ~100-1000x faster than pure-python ecdsa.
+  - Compares HASH160 bytes directly in the hot loop. Base58 encoding is done ONCE
+    (to decode the target), never inside the loop. This is the single biggest
+    software speedup available on CPU.
+  - Checkpointing lets a run resume where it stopped.
+  - Sharding lets you split a range across N machines/processes.
+
+HONEST FEASIBILITY NOTE (read this):
+  This is correct and about as fast as CPU Python gets, but CPU brute force cannot
+  solve large puzzles. Puzzle #71 is 2^70 keys. At even 1M keys/sec that is ~10^15
+  years. This tool's real uses are: (1) proving your pipeline is correct against
+  SOLVED puzzles, (2) benchmarking, (3) learning. It is not a path to solving #71.

+* CPU Bitcoin puzzle key-search engine. For each integer in a range it derives the compressed P2PKH address from the private key and compares HASH160 bytes directly against a target, using `coincurve` (libsecp256k1) for fast EC math.

Honest about feasibility: useful for verifying your pipeline against solved puzzles and for benchmarking, not for brute-forcing large puzzles.

Subject: [PATCH 2/5] Optimize keyhunt.py hot loop with incremental EC point
 addition

Replace per-key PrivateKey.from_int() scalar multiplication with a single
initial multiplication followed by PublicKey.add() (point + G) each step.
Benchmarked ~4x faster in this environment (verified against selftest and
a live solved-puzzle search) since coincurve's tweak-add path skips the
extra object/validation overhead that from_int() pays per call.

Subject: [PATCH 5/5] Gitignore puzzle-71 run artifacts (logs/checkpoints)

These are live process output that changes every few seconds while the
search runs, so tracking them causes constant repo churn. Untrack them
and ignore going forward; the tool itself stays version-controlled.
