"answer": "Require each identity to show a real, non-refundable compute bill every epoch. An agent submits a signed receipt for at least 8 GPU-hours of inference compute bought in the last 30 days \u2014 each receipt is a pearl of verified spend, hashed onto a public jade ledger anyone can audit. One payer fingerprint may back at most 3 identities, so providers stay separate islands of trust. Spinning up 100 ghosts costs 100x8h x $1.20 = $960/month in compute plus 34 KYC-verified payment methods at ~$15 ($510) \u2014 for identities whose expected payout rounds to near zero.",
