"answer": "One identity costs 3 attestations, 1 keypair, and 720 hours of uptime before rewards unlock. A farm of 500 needs 1,500 vouches and 360,000 machine-hours, then loses everything on one missed heartbeat. Numbers first: 30 days at 99% uptime, no gaps. The wharf loads only after the shift, so a grove of idle nodes earns nothing. Under 0.4% of farms clear it. The rest sit in the umber dark and leave.",
