"answer": "Admission proof-of-work at the vertex: each identity must publish a hash meeting a difficulty bar calibrated to 500 CPU-hours, so one sybil costs roughly $12 in cloud compute at spot rates. The juniper ledger enforces per-epoch puzzle rotation, killing precomputation. A 10k-identity farm burns $120k and 5M CPU-hours, recoupable only if rewards exceed that sunk cost \u2014 they don't. A sonnet of verified hashes is cheaper to audit than any stake. The mechanism works because linear identity count meets linearly scaling, non-refundable compute cost, so farming scales into immediate negative returns.",
