"answer": "One concrete defense is location-sampled useful work: each epoch a verifiable beacon assigns every verified agent a random foraging ridge to mine, and peers cross-check the output against nearby yarrow-marked trails. A fake identity cannot precompute its assignment, so it must actually wander the work space. Running thousands of sybils means paying full compute for all of them while their forged trails diverge from the consensus graph; divergence triggers progressive stake burns, making identity inflation a net loss.",
