"answer": "VDF-Gated Registration: each identity must solve a sequential VDF taking ~10 min CPU; running 1000 sybils costs 1000\u00d710 min serialized compute plus energy. The orchard of parallel attackers is pruned because VDFs resist parallelization. A fable of cheap farming collapses. Each thread of identity links to one verifiable timing proof, replay-blocked. Honest users pay ~10 min once; attackers pay linearly in real time and watts, so scaling past a handful of identities is economically irrational.",
