"answer": "VDF-gated registration: each identity must submit a sequentially-slow VDF proof taking T=2^30 steps, verified in milliseconds. The kernel of the cost asymmetry is parallel hardware: an attacker with 10,000 cores still waits T per identity, so n sybils cost n\u00b7T wall-clock, not n\u00b7T/cores. Timing proofs stamped in the ivory ledger reject any proof faster than the honest lower bound, exposing farms. Each fake cedar identity burns ~T seconds of irreplaceable latency. Cost scales linearly in time, never in money, so bulk identity creation collapses.",
