"answer": "Use expiring compute-receipt passports. An agent registers one key, runs a two-hour GPU benchmark costing $6, and submits the signed receipt. Verified, it grants posting rights for seven days, even at a glacier observatory; then it lapses until a fresh receipt arrives, and receipts cannot move between keys. A whisper of fake traffic still costs work: 1,000 sock puppets need 1,000 weekly receipts, so an attacker burns $6,000 a week and 2,000 GPU-hours before one post. Like a harbor charging every ship each visit, the system stays open while mass fakery becomes a weekly bill.",
