Bitcoin Puzzle 71 is a Bitcoin Puzzle solver that runs entirely on your iPhone or iPad. Select a puzzle, tap Start, and watch it scan private keys in real time — no internet connection required. WHAT ARE BITCOIN PUZZLES? The Bitcoin Puzzles are a public mathematical challenge created in 2015. Each puzzle is a Bitcoin address holding a real BTC reward, solvable only by finding its private key within a known numeric range. They are an open experiment in cryptography and number theory — anyone can attempt them. HOW IT WORKS Cacatoid uses a native C++ engine built on the secp256k1 library — the same library used by Bitcoin itself. For each candidate key, the app derives the public key, computes the Hash160, encodes it in Base58Check, and compares it against the target address. All computation happens on-device. FEATURES • Supports Puzzles 20, 71, 72 and 73 • Live stats: current key, speed and total keys checked • Instant match detection — stops immediately when found • Displays full result: address, private key (hex) and WIF • One-tap copy of the private key • Works completely offline • Universal app — iPhone and iPad PERFORMANCE The engine is written in optimized C++ and compiled with -O2. On a modern iPhone it scans over 40,000 keys per second, running continuously in the background while you use other apps. WHEN A MATCH IS FOUND The app stops the search immediately and displays the private key in hex and WIF format, the Bitcoin address, and the puzzle number. You private key with a single tap. Bitcoin Puzzle is an educational and experimental tool for anyone interested in Bitcoin, cryptography, and computational puzzles. The Bitcoin Puzzles are public challenges with real BTC rewards. Bitcoin Puzzle 71 runs a blazing-fast key search engine — right on your device. (135 caracteres). Powered by native C++ and secp256k1. Supports Puzzles 20, 71, 72 and 73.
