"Hongik Ingan: Distributed networks empower everyone to be their own host."
Your PC as Server ================= Traditional server: - Runs 24/7 in data center - Expensive hardware - Managed by company - You pay rent WIA-HOME server: - Runs on your PC/laptop - Uses minimal resources - You control everything - Zero cost Server Components ================= 1. HTTP Server - Serves web pages - Handles requests - Optimized for low resources 2. P2P Node - Connects to mesh network - Handles NAT traversal - Enables discovery 3. Content Manager - Stores your pages - Manages media - Handles caching 4. Security Layer - TLS encryption - DDoS protection - Firewall Resource Usage ============== Minimum requirements: CPU: 5-10% when active Memory: 128-256 MB Storage: 100 MB + your content Network: 1 Mbps upload Your old laptop can do this! Sleep Mode ========== When no visitors: - Server enters sleep mode - Uses almost no resources - Wakes on incoming request - Seamless for visitors Energy efficient hosting.
Network Topology

No Central Server
=================
Traditional:
All traffic -> Central server -> Users
Server down = Website down
WIA-HOME:
Traffic distributed across network
Your PC down = Cached content served
Network resilient
Peer Discovery
==============
1. Bootstrap
- Connect to known peers
- Get peer list
- Join network
2. DHT (Distributed Hash Table)
- Store domain mappings
- No central DNS required
- Resilient to failures
3. Gossip Protocol
- Share peer information
- Health monitoring
- Load balancing
The NAT Problem =============== Most home networks use NAT: - Internal IP: 192.168.1.x - External IP: Single public IP - Incoming connections blocked Need to punch through NAT. NAT Types ========= Open (10%): [OK] Direct connection possible [OK] No special handling needed Full Cone (30%): [OK] Port forwarding works [OK] Predictable ports [i] Some setup needed Restricted (40%): [i] Hole punching required [i] Coordination needed [OK] Usually works Symmetric (20%): [!] Most restrictive [!] Different port per connection [!] Relay required Traversal Techniques ==================== 1. STUN (Session Traversal) - Discover external IP/port - Works for most NATs - Low overhead 2. TURN (Relay) - Use relay server - Works for all NATs - Higher latency 3. ICE (Interactive Connectivity) - Try all methods - Select best option - Automatic fallback WIA Implementation ================== Automatic detection: 1. Detect NAT type 2. Try direct connection 3. Try hole punching 4. Fallback to relay User sees: "Your site is live!" (All complexity hidden)
Domain System ============= Traditional DNS: - Centralized servers - Annual renewal fees - Can be seized/blocked - Dependent on registrar WIA DNS: - Distributed across network - Free forever - Censorship resistant - You control it Domain Format ============= yourname.wia.home - Personal site - Portfolio - Blog yourname.wia.shop - E-commerce - Business site - Product catalog yourname.wia.blog - Blog focused - Content site - Publications yourname.wia.page - Single page - Landing page - Project page Registration ============ Register domain: 1. Choose name 2. Generate keypair 3. Sign registration 4. Broadcast to network Ownership: - Proven by cryptographic key - No central authority - Cannot be taken away Custom Domain (Optional) ======================== Already have domain? - Point DNS to WIA network - Both addresses work - Gradual migration possible
CDN Without CDN =============== Traditional CDN: - Edge servers worldwide - Expensive ($50-500/month) - Provider-dependent WIA P2P Distribution: - Peers cache popular content - Automatic distribution - Free and decentralized How It Works ============ 1. First Request Visitor -> Your PC -> Content 2. Subsequent Requests (same area) Visitor -> Nearby peer (cached) -> Content 3. You Go Offline Visitor -> Multiple peers (cached) -> Content Cache Strategy ============== Hot content (popular): - Cached on many peers - Fast delivery - High availability Cold content (rare): - Direct from origin - On-demand caching - Still accessible Benefits ======== [OK] Fast delivery (nearby peers) [OK] High availability (redundancy) [OK] Free (no CDN costs) [OK] Scales automatically [OK] Works even when you sleep
