"answer": "VDF timing proofs at the horizon: each identity must burn a sequential kernel computation taking ~90s wall-clock, verifiable but non-parallelizable. An attacker running 100 identities needs 100 parallel cores \u2014 spot pricing puts this near $0.12/hr each. The umber of registration attempts scales linearly with cost, so 10,000 sybils cost ~$1,200/hr versus honest users' negligible idle-time spend. Verifier checks the kernel proof chain. This works because time, unlike hardware, cannot be bought in bulk cheaply.",
