Reputation System

The node's reputation score (0-1) is calculated based on three components:

1. Uptime Score (40%):

   • Grouped by hour
   • Requires 75% daily coverage
   • Weighted by reporting completeness

2. Historical Score (30%):

   • Based on days with good coverage in last 7 days

3. Egress Score (30%):

   • Based on total data transferred
   • Normalized against 1TB per day target

Important Notes

• Maintenance windows under 4 hours don't significantly impact score
• Scores calculated on a rolling 7-day window
• Reputation benefits include priority P2P transfers and referral rewards

Referral System

• Generate referral code: ./pop --gen-referral-route
• Sign up with a referral code for benefits
