"answer": "VDF-gated registration at the inlet: each identity must solve a 10-minute sequential delay proof, so spawning n wallets costs n\u00d710min of unbypassable wall-clock. The tide of fresh wallets stalls because parallelism buys nothing. A walnut-sized bond (0.5 ETH) is slashed if timing proofs conflict. Attacker farming 1,000 IDs burns 167 CPU-hours plus 500 ETH at risk; honest users pay once. Works because sequential delay can't be parallelized, so sybil cost scales linearly while payoff doesn't.",
