  • Lightning Pioneer: First messenger with Lightning Network integration
  • Military-Grade Security: 12-layer defense system exceeding government standards
  • True P2P: Zero servers, impossible to censor or shutdown

✨ What's New in v4.0

🔐 Enhanced Security Architecture

  • ECDH P-384 elliptic curve key exchange (military-grade)
  • AES-GCM 256-bit authenticated encryption
  • ECDSA P-384 digital signatures for message integrity
  • Perfect Forward Secrecy with automatic key rotation every 5 minutes
  • Out-of-band verification codes to prevent MITM attacks
  • Non-extractable keys with hardware protection

⚡ Lightning Network Integration

  • Pay-per-session model with instant satoshi payments
  • WebLN support for all major Lightning wallets
  • Sustainable economics without ads or data harvesting
  • Session types: Demo (6 min), Basic (1h/50 sats), Premium (6h/200 sats)

🌐 Pure P2P Architecture

  • Direct WebRTC connections without any servers
  • Complete decentralization - impossible to block or censor
  • Zero registration required - instant anonymous channels
  • NAT traversal and firewall bypass capabilities

🎭 Advanced Privacy Features

  • Traffic obfuscation with fake traffic generation
  • Packet padding and pattern masking to defeat traffic analysis
  • Metadata protection - full encryption of all communications metadata
  • Zero data storage - messages exist only in browser memory
  • Session isolation - complete cleanup between sessions

🎨 User Experience

  • Modern responsive design with dark theme
  • Real-time security indicators showing encryption status
