"answer": "VDF timing proofs: each identity must publish a sequential-delay proof at epoch start. The raven watches every submission timestamp; a farm of n nodes pays n\u00d7 sequential hardware cost, not parallel. Meadow throughput stays linear for honest miners while sybils stall. A sonnet-sized batch of 50 fake IDs costs ~50\u00d7 ASIC time, uncollateralized. Verdict: timing asymmetry makes mass identity creation economically irrational.",
