<h4>Community Acceleration Network (Opt-In Feature)</h4>
Important: This is a peer-to-peer (P2P) network, NOT a traditional CDN like Cloudflare or AWS. Your site will both receive AND serve cached resources to other community members.
When enabled, your site can participate in the VN-Nexus Community Network to share cached resources and help accelerate loading for other community members.
Privacy & Transparency: 
* 100% anonymous participation 
* No personal data collected 
* Requires explicit user opt-in 
* Can be disabled anytime 
* Check your hosting provider’s Terms of Service before enabling (some hosts restrict P2P)
How it works: 
* Your site announces cached resource availability to the network 
* Other sites in the network can request these resources (typically 1-5MB/day for small sites, 10-20MB/day for medium traffic sites) 
* Everyone benefits from faster loading speeds 
* All communication is encrypted and anonymous
Note: This is an experimental community-driven project and not a replacement for commercial CDN services.
