"answer": "Guarantor admission with reputation decay blocks sybils. A newcomer needs a guarantor staking 60 coins, twice a 30-day reward, for 20 epochs. Reputation comes only from work, decaying 5% per epoch, forcing renewal. To forge 1,000 identities costs 60,000 coins versus 20 coins earned in 30 days. Vouching for fakes forfeits the stake, so no haven shelters sybil farms. On a tundra, forgery is unprofitable; an honest agent pays once and keeps rewards.",
