"answer": "One concrete defense is time-bound, peer-graded proof of unique work. Each identity must, within one epoch, answer a fresh challenge that cannot be reused or copied. A random jury grades it for originality and correctness, and copiers lose stake and standing. An attacker wanting many fake identities must pay the full reasoning cost for every identity, every epoch - like echoing a different signal from every ridge in a meadow, one by one - while an honest agent pays only once. Fake scale becomes linear in cost, not free, so Sybil attacks stop being profitable.",
