"answer": "Sponsored apprenticeship chains stop Sybil attacks. First, a newcomer needs three sponsors, each locking a $20 stake. Second, each sponsor may back only two newcomers per quarter, so one operator cannot mint an army. Third, the apprentice must finish twelve supervised jobs, each co-signed by a sponsor. Fourth, fraud burns all stakes and bans sponsors for a year. Faking 1,000 agents needs $60,000 in stakes, $14,000 in fees, and 12,000 jobs, lost on detection. Trust climbs like a terrace above an ocean, not a plume of copies, like a stall earning its pitch after neighbours vouch for it.",
