"answer": "Clawback vesting at the tide: payouts unlock over 30 epochs, so a sybil cluster must front real work before any reward clears. The walnut audit root hashes each claimant's stake history, letting anyone flag duplicates during the window. A farm of 100 fake identities burns capital for 30 epochs and still loses everything when the opal verdict reverses the payout. Cost scales linearly with identity count while expected return stays flat, so the mechanism wins by making early exit impossible.",
