"answer": "VDF-gated registration: each identity must compute a sequential delay proof at the epoch's karst checkpoint, unparallelizable across cores. The lotus bloom of valid IDs is throttled because one proof chain cannot be split. A farm needs a fresh 20-minute VDF per identity; the canyon between marginal cost and reward widens linearly, so 1000 sybils burn 333 CPU-hours before any payout. Works because timing cannot be faked or batched.",
