Welcome to the official documentation for Zelf Name Service (ZNS) - the world's first commercialized Zero Knowledge Face Proof™ system.

Zelf Name Service (ZNS) is a revolutionary way of seed phrase (mnemonic key) storage, featuring cutting-edge privacy-preserving non-biometric encryption. This innovative wallet management solution ensures security without storing or exposing biometric data. The end user's face generates a unique, non-biometric binary representation called ZelfProof, which facilitates highly secure encryption and decryption.

• 🔒 No Biometric Storage: Biometric data is never stored - only used to generate encrypted, randomized, privacy-preserving binary representations
• 👁️ Liveness Detection: Verifies end user presence, preventing spoofing attempts
• 📱 Offline Capability: Works both online and offline, requiring no internet connection
• 💾 Easy Storage: Store private information in QR codes containing ZelfProof, with optional IPFS backup
• 🔄 Revocable: ZelfProofs can be revoked and regenerated for enhanced security
• 🌐 Distributed: Supports fully offline verification for decentralized systems

This documentation website is built using Docusaurus, a modern static website generator that provides:

• Fast Performance: Static site generation for optimal loading speeds
• SEO Optimized: Built-in SEO features for better search visibility
• Mobile Responsive: Works seamlessly across all devices
• Search Functionality: Built-in search for easy content discovery
• GitBook-style Design: Custom styling to replicate the professional GitBook aesthetic

npm install

npm start

This command starts a local development server at http://localhost:3000. Most changes are reflected live without having to restart the server.

npm run build

This command generates static content into the build directory and can be served using any static content hosting service.

For production environments, you can use PM2 to manage the Docusaurus development server as a persistent process.

npm install -g pm2

pm2 start "npm start" --name "zelf-docs"

# View running processes
pm2 list

# Restart the documentation server
pm2 restart zelf-docs

# Stop the documentation server
pm2 stop zelf-docs

# View logs
pm2 logs zelf-docs

# Monitor in real-time
pm2 monit

# Save PM2 configuration
pm2 save

# Setup PM2 to start on system boot
pm2 startup

For better performance in production, you can build the static site and serve it with PM2:

# Build the static site
npm run build

# Install serve globally
npm install -g serve

# Start serving with PM2
pm2 start "serve -s build -l 3000" --name "zelf-docs-static"

Using SSH:

USE_SSH=true npm run deploy

Not using SSH:

GIT_USER=<Your GitHub username> npm run deploy

If you are using GitHub pages for hosting, this command is a convenient way to build the website and push to the gh-pages branch.
