Add live blockchain explorer with REAL proof-of-work mining!
Created blockchain-dynamic.html - Full blockchain implementation: 🔥 REAL FEATURES: ✅ Client-side proof-of-work mining (SHA-256) ✅ Adjustable difficulty (4 leading zeros) ✅ Real hash rate calculation ✅ Nonce discovery with attempt tracking ✅ Valid block generation ✅ Transaction creation ✅ Live blockchain visualization ✅ Genesis block creation ✅ Previous hash linking ✅ Timestamp verification Mining Process: - Click "Start Mining" to mine a real block - Watch live hash attempts (1000 hashes/iteration) - See nonce discovery in real-time - Valid blocks added to chain - Hash rate displayed (H/s) - Mining stats: attempts, time, difficulty Transaction Features: - Create RoadCoin transactions - Send to any address - Real-time status (confirmed/pending) - Transaction history display - Amount tracking Stats Dashboard: - Total blocks mined - Total transactions - Network difficulty - Live hash rate This is a FULLY FUNCTIONAL blockchain running in the browser! Uses CryptoJS for SHA-256 hashing. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
