🎯 Enhanced C2Pool - Refactored Implementation

C2Pool has been completely refactored with enhanced features and clear terminology separation:

✨ Key Improvements

• 🔄 Share Type Separation - Clear distinction between:
  • mining_shares - From physical miners via Stratum protocol
  • p2p_shares - From cross-node P2Pool communication
• ⚡ Automatic Difficulty Adjustment (VARDIFF) - Dynamic mining difficulty
• 📊 Real-time Hashrate Tracking - Accurate performance monitoring
• 💾 Persistent Storage - LevelDB-based sharechain persistence
• 🌐 Web Interface - JSON-RPC mining interface with monitoring
• 🔐 Blockchain-specific Address Validation - Multi-coin support
• 📈 Enhanced Statistics - Separated mining vs P2P metrics

🏗️ Modular Components

• hashrate/ - Real-time hashrate tracking with mining_share metrics
• difficulty/ - Automatic difficulty adjustment engine
• storage/ - Persistent LevelDB sharechain storage
• node/ - Enhanced C2Pool node implementation
• archive/ - Legacy code archive (for reference only)

🚀 Quick Start

Building

git clone https://github.com/username/c2pool.git
cd c2pool
mkdir build && cd build
cmake ..
make c2pool        # Primary executable (refactored)
make c2pool_enhanced  # Explicit enhanced version

Running

# Integrated mining pool for Litecoin testnet
./c2pool --integrated 0.0.0.0:8084 --blockchain ltc --testnet

# Enhanced sharechain node
./c2pool --sharechain --testnet --port 9333

# Help
./c2pool --help

📊 Current Implementation

• Primary Entry Point: src/c2pool/c2pool_refactored.cpp
• Build Targets: c2pool (primary), c2pool_enhanced (explicit)
• Legacy Files: Archived in archive/ directory for reference

Build Enhanced C2Pool

mkdir -p build && cd build
cmake ..
make c2pool_enhanced -j4

Run Mining Pool with Web Interface

./src/c2pool/c2pool_enhanced --testnet --integrated 0.0.0.0:8083

Access web interface at: http://localhost:8083

Run Enhanced Sharechain Node

./src/c2pool/c2pool_enhanced --testnet --sharechain

Available Options
