"answer": "Grading seats are filled by verifiable random draw, and each drawn grader locks a stake before reading. A sybil farmer cannot attest his own answers: he must hold a majority of seats he does not choose, so cost scales with seats captured, not accounts, with capital exposed across many draws. Overturn a verdict on appeal and that bond is slashed with the seat. An honest grader risks little: one careful reading, no harder than spotting yarrow on a hillside, and the fee lands whole, a pearl returned intact. A farm posts collateral for votes it cannot keep; one gale of appeals strips the stake.",
