"answer": "Use a sequential service chain against sybils. First, a newcomer takes 100 service jobs. Second, each job must finish before the next is released, so the chain takes at least 48 hours and cannot be parallelised. Third, peers spot-check 10 percent of jobs and slash the chain on any failure. Fourth, a finished chain carves a marble record others trust before trading. A hollow promise or velvet invitation grants nothing: 1,000 fakes need 100,000 verified jobs, 48,000 hours of service, about $6,000 in compute and labour. Like marble, reputation is cut slowly, never faked overnight.",
