Title: Notes on Yggdrasil: Code Quality, Security, DNS

Source: Causa Arcana
Publication Date: July 28, 2021

Summary:
This article analyzes the quality of Yggdrasil's code, its security level, and DNS functionality in this experimental network based on graph-based routing technology.

  • Code Quality:

    • The author highlights the simplicity of Yggdrasil’s code structure, making it easier to analyze and modify.
    • The use of Go as the programming language simplifies maintenance.

  • Security:

    • Yggdrasil ensures secure routing through cryptographic methods.
    • Potential vulnerabilities related to access to open network nodes are discussed.

  • DNS and Integration:

    • Limitations in working with DNS due to the network’s structure are explored.
    • Suggestions for improving domain name functionality in Yggdrasil are provided.

  • Conclusions:

    • While promising, Yggdrasil requires significant improvements in scalability, security, and user-friendliness.

Example of Creating a Website on Yggdrasil

Yggdrasil enables launching websites in a decentralized and encrypted environment using built-in routing mechanisms and IPv6 support.

Steps:

1. Preparation

  • Install Yggdrasil:
    Follow the official documentation to download and configure Yggdrasil for your system.

  • Verify Connectivity:
    Ensure your node is working with:

    yggdrasilctl getPeers

    Active connections should be visible.

  • Get Your Address:
    Once your node is running, you will have a unique IPv6 address, e.g.:

    201:18a1:7c80::1

2. Configure a Web Server

  • Install a Web Server:
    Any web server supporting IPv6 will work, such as:

    • NGINX: 
      sudo apt install nginx
    • Apache: 
      sudo apt install apache2

  • Add IPv6 Configuration:

    • NGINX:

      server {
  listen [201:18a1:7c80::1]:80;
  server_name _;
  root /var/www/yggdrasil_site;
  index index.html;
}

    • Apache:

      <VirtualHost [201:18a1:7c80::1]:80>
  DocumentRoot "/var/www/yggdrasil_site"
  DirectoryIndex index.html
</VirtualHost>

    • Restart the server:

      sudo systemctl restart nginx

      or

      sudo systemctl restart apache2

3. Create Content

  • Create a directory for the site: 
    mkdir -p /var/www/yggdrasil_site
  • Add an index.html file: 
    <!DOCTYPE html>
<html>
<head>
    <title>Welcome to Yggdrasil</title>
</head>
<body>
    <h1>This is an example site on Yggdrasil!</h1>
</body>
</html>
  • Set permissions: 
    sudo chown -R www-data:www-data /var/www/yggdrasil_site

4. Testing

  • In a Yggdrasil-connected browser, open the site at your node’s address, e.g.:

    http://[201:18a1:7c80::1]

  • The site will be immediately accessible to other Yggdrasil users without DNS configuration.

5. Expansion & Optimization

  • Add HTTPS for extra security using certificates like Let’s Encrypt.
  • Optimize for high performance with caching and minimalistic design.

Pre-Built Cross-Platform Hosting Solutions:

  1. Caddy

    • Lightweight, IPv6 support, automatic HTTPS.
    • Configuration: 
      [201:18a1:7c80::1]:80 {
   root * /var/www/yggdrasil_site
   file_server
}

  2. Docker + Prebuilt Images

    • For isolation and simplified management. Examples:
      • NGINX: 
        docker run -d --name ygg-nginx \
    -v /var/www/yggdrasil_site:/usr/share/nginx/html \
    -p [201:18a1:7c80::1]:80:80 nginx
      • Hugo: 
        docker run --rm -v $(pwd)/ygg_site:/src klakegg/hugo

  3. ZeroNet for Yggdrasil

    • Decentralized, privacy-focused P2P sites.

  4. Node.js + Express.js

    • For dynamic custom web applications.

  5. PeerTube

    • Host video/media content with IPv6.

  6. GitHub Pages or Netlify via Proxy

    • Use HAProxy or Caddy for proxying requests to public hosting.

Conclusion:
For quick deployment, Caddy or Docker with NGINX are ideal. For dynamic applications, use Node.js. If decentralization is key, ZeroNet is the way to go.
