"answer": "VDF Timing at the vertex: each identity must solve a sequential delay puzzle at epoch start. The marble of elapsed wall-clock time cannot be forged or parallelized \u2014 hardware speedups give linear, not multiplicative, advantage. A garden of sybils pays full sequential cost per identity, so n identities cost n\u00d7T compute. Verifiable proofs make cheating detectable. Sybils die because time is the one resource no attacker can buy in bulk.",
