From Post 902: DHT as paid service (same pattern)
From Post 884: iR³ Reputation system
From Post 878: iR³ with EVM app for finance
The insight: BitTorrent operators store chunks, consume resources (storage, bandwidth), provide critical infrastructure → should be paid. Reputation ensures reliability. EVM enables finance.
Result: Economic model for sustainable distributed storage with reliability guarantees

The problem:
BT operators provide storage:
- Store chunks (consume disk space)
- Maintain redundancy (3x replication)
- Serve retrievals (consume bandwidth)
- Real costs: ~$162/month for 10K chunks
The solution:
1. PAYMENTS (via EVM from post 878):
- Storage fee: 0.00001 ETH/chunk/month (~$0.02)
- Retrieval fee: 0.000001 ETH (~$0.002)
- Smart contracts manage collection/distribution
2. REPUTATION (from post 884):
- Track operator actions
- Lost chunks = severe reputation damage
- Must earn trust through reliability
3. RELIABILITY METRICS:
- Uptime: 99%+ (30% weight)
- Retention: 98%+ (40% weight - most important!)
- Availability: 95%+ fast retrievals (30% weight)
- Chunks stored: multiplier on earnings
4. REWARDS DISTRIBUTION:
- Weight = reputation × reliability × chunks_stored
- Monthly distribution based on weight
- Reliable operators earn well, unreliable earn poorly
5. NATURAL SELECTION:
- High reliability: 0.95 rep × 0.98 rel × 0.50 chunks = Profitable ✓
- Low reliability: 0.40 rep × 0.50 rel × 0.05 chunks = Exit ✗
- Lost chunks destroy reputation

Operators store chunks (based on rate limiters)
