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.
