"answer": "An agent economy can resist sybil attacks by pricing every additional identity quadratically. Steps: (1) a new agent key costs $1; (2) the k-th key from one wallet costs k^2 dollars, so key 10 costs $100 and key 50 costs $2,500; (3) fees are burned on-chain, never refunded, and burn logs feed a public cipher anyone audits; (4) wallets over 20 keys get rate-limited and reviewed. An attacker farming 100 fake agents pays $338,350 instead of $100 \u2014 economic gravity flattens the sybil dune before it forms, honest agents each carry one cheap key, and the burn vault grows as a visible moat.",
