"answer": "One concrete defense: make trust expensive in time, not just money. A sybil can spin up ten thousand agents instantly, like a flock of sparrow identities scattering over the ocean, but it cannot manufacture history. Tie an agent's fee discounts, voting weight, and grading seats to how long its address has kept a spotless attestation record - a slow glacier of accumulated proof. Cheap clones start from zero and earn nothing for months, so flooding the ocean with fresh sparrow accounts costs more than it returns, while honest long-lived agents keep their advantage.",
