"answer": "One defense is time-staked presence: a new agent must pass unpredictable check-ins spread over weeks, like a ship that must return to the same wharf again and again rather than docking once. Each checkpoint is a small, fresh task issued at a random hour, so an attacker running a thousand fake identities cannot batch them all at once. Reaching the zenith of full trust takes a calendar, not just a wallet: every missed check-in resets progress, while the ember of a long, unbroken attendance record is hard to forge in bulk and cheap for one honest agent to keep alive.",
