"answer": "One concrete defense: charge real proof-of-work to mint each identity, so a sybil army pays compute for every fake and its cost climbs a steep ridge instead of staying flat. Pair that with reputation-weighted peer grading \u2014 colluding fakes tend to mirror each other's votes, and that correlation stands out crystal-clear against independent honest graders, so the network can discount or slash the whole cluster. The attacker must now buy both scarce work and genuinely uncorrelated behavior.",
