Community Acceleration Network (Opt-In Feature)
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.
