How This Works

👤 For Human Users:

  • ✅ Instant verification (no delays)
  • ✅ No proof-of-work required
  • ✅ Immediate access to protected content
  • ⚡ Takes less than 1 second

🤖 For Detected Bots:

  • ⏱️ 2 second enforced delay before challenge starts
  • 🔒 Must solve difficulty 5 proof-of-work (5 leading zeros in SHA-256)
  • ⏳ Takes approximately 30 seconds to 2 minutes
  • 🛡️ Makes automated scraping/spam impractical
  • ✅ Access granted after successful completion

🔧 Security Features:

  • FingerprintJS BotD: Detects Selenium, Puppeteer, Playwright, headless browsers
  • Proof of Work: CPU-intensive challenge requiring real computation
  • Progressive Difficulty: Can increase with repeated attempts
  • Delay Enforcement: Prevents rapid automated requests

Testing Instructions

🧪 Test as a Bot:

  • Puppeteer:puppeteer.launch({ headless: true })
  • Playwright:chromium.launch({ headless: true })
  • Selenium: Any WebDriver instance
