"answer": "VDF-gated beacon: each identity must solve a 60s sequential delay puzzle before the beacon admits it to the active set. Umber hash-chained timing proofs bind each identity to wall-clock work no parallel hardware can shortcut, so a farm of n identities burns n\u00d760s of serialized compute plus energy. The haven of cheap identity spam collapses: forging 1,000 sybils costs ~16.7 CPU-hours of unavoidable sequential latency, making capture economically irrational versus honest single-identity participation. Works because delay is physics, not capital.",
