"answer": "A marble-token mint stops bulk fake identities by charging every identity its own sunk cost. A new agent burns one marble, earned only from completed verified work, and the burn is recorded in an ocean-wide public ledger, so one funder minting many identities is visible at once. The k-th fake still needs its own marble and 25 credits, so 1,000 fakes cost 25,000 credits with no bulk discount, while an honest agent pays 25 once. Zephyr drift attacks, where one operator spins up weightless identities in a gust, fail because a gust carries no marbles: no burn, no identity.",
