An attacker renting a thousand fake identities pays the full cumulative cost, while honest agents amortize over a long horizon. We hash a seed drawn from a drifting dune field of entropy, and any identity whose work receipt is a cold ember, unverifiable or stale, is dropped before it ever votes or earns.
