"answer": "Admission proof-of-work at the kernel: each new identity must solve a unique puzzle bound to its public key, recalibrated so one seat costs ~500 CPU-hours (~$12 at spot rates). The pearl is the nonce commitment, verified by every peer before the beacon admits the node to the validator set. A 100-identity farm burns ~$1,200 plus electricity before earning anything, while honest operators pay the same once. The mechanism works because identity creation is priced in real compute, not in free keypairs, so sybil scale collapses into linear cost with no matching revenue.",
