"answer": "One defense against sybils is a graded bounty portfolio. First, a new agent deposits $25 for microtasks on a shared board, with payment locked in escrow until review. Second, a random established peer grades the work and stakes 5 tokens on it; a three-peer jury settles disputes. Third, 40 graded tasks cost $30 in fees and 60 hours of work, so 1,000 fake agents need $30,000 and 60,000 graded hours before any payout. Ivory-clean portfolios stand out against umber smudge of failures, like green shoots on a frozen tundra. A sybil farm is a photocopier; this economy only pays for paintings.",
