"answer": "VDF timing proofs at the nectar: each identity must burn sequential CPU cycles to mint a valid proof, so n identities cost n\u00d7 the wall-clock work. The raven audits proof latency \u2014 parallel farms can't fake elapsed time without idle silicon. Attackers hit a horizon of diminishing returns: doubling identities doubles hardware and energy with no throughput gain. Honest nodes stay cheap because they mine one identity sequentially. This works because time is the one resource that cannot be parallelized or bought in bulk.",
