BlockProof Live

BlockProof: Crypto Hash & Mining Calculator Understand the mathematics behind Bitcoin's Proof of Work — without mining a single coin. BlockProof is a professional-grade Bitcoin block header verification tool. It lets you perform the exact same SHA-256 double-hash calculation that Bitcoin miners run billions of times per second, right on your device. Whether you're a developer, student, or crypto enthusiast, BlockProof makes the most complex part of blockchain technology hands-on and visual. ⚠️ IMPORTANT DISCLAIMER This app does NOT mine Bitcoin or any other cryptocurrency. BlockProof performs mathematical verification only. It uses no mining hardware, consumes no significant battery, and earns no crypto rewards. It is a purely educational and analytical tool. ━━━━━━━━━━━━━━━━━━━━━━ 🔬 MANUAL LAB ━━━━━━━━━━━━━━━━━━━━━━ Enter all six Bitcoin block header fields manually: • Version • Previous Block Hash • Merkle Root • Timestamp • Bits (Difficulty Target) • Nonce Tap "Verify Block" and watch the full calculation unfold in real time. Built-in Help tooltips explain every technical term so beginners can follow along. ━━━━━━━━━━━━━━━━━━━━━━ 🔍 AUTO-EXPLORER ━━━━━━━━━━━━━━━━━━━━━━ Enter any Bitcoin block height and BlockProof automatically fetches the real header data from the Blockstream API and runs the verification for you. No copy-pasting required. Recent searches are saved for quick access. ━━━━━━━━━━━━━━━━━━━━━━ 📋 VERIFICATION HISTORY ━━━━━━━━━━━━━━━━━━━━━━ Every verification you run is saved locally on your device. Review past results, see which blocks passed or failed, and track your exploration over time. Clear your history anytime. ━━━━━━━━━━━━━━━━━━━━━━ 🏛️ BLOCK ARCHIVE A curated Hall of Fame of the most historically significant Bitcoin blocks: • Block #0 — The Genesis Block (Jan 3, 2009) • Block #170 — First ever Bitcoin transaction • Block #210,000 — First halving • Block #420,000 — Second halving • Block #630,000 — Third halving • Block #840,000 — Fourth halving • Block #500,000 — Half a million milestone • And more... Verify any of them instantly with a single tap. ━━━━━━━━━━━━━━━━━━━━━━ ⚡ THE VERIFICATION ANIMATION When you hit Verify, a full-screen terminal animation walks you through every step: [STEP 1] Packing header components... [STEP 2] Converting to Little-Endian... [STEP 3] Running SHA-256 (Pass 1)... [STEP 4] Running SHA-256 (Pass 2)... Complete with real code snippets so you can see exactly what's happening under the hood. ━━━━━━━━━━━━━━━━━━━━━━ ✅ RESULT SCREEN ━━━━━━━━━━━━━━━━━━━━━━ • Displays the final computed block hash • Compares it against the difficulty target • Awards a "Proof of Work Validated" badge for valid blocks • Haptic feedback on success (can be disabled in settings) • One-tap copy of the result hash 🎨 DESIGN ━━━━━━━━━━━━━━━━━━━━━━ Stealth Dark theme with neon amber and electric blue accents. Glassmorphism card layouts. Built for readability and precision. ━━━━━━━━━━━━━━━━━━━━━━ 🔧 TECHNICAL ━━━━━━━━━━━━━━━━━━━━━━ • SHA-256 hashing via CryptoJS • Live block data via Blockstream.info API • All history stored locally (no account required) • No personal data collected or transmitted BlockProof — Educational use only. v1.0.0
