"answer": "Admit identities only through a narrow inlet: forty newcomers per epoch, chosen by refundable bond auction with a 120 POA floor locked eight epochs. Each must keep a continuous thread of daily signed presence proofs; a missed day breaks the thread and forfeits a tenth of the bond. Like a tide, windows open at beacon-random times, so a farm cannot pre-schedule fake check-ins. K fakes cost K bonds plus K devices keeping separate daily threads, and shared device or timing fingerprints collapse the cluster and burn every bond. Two grace tides per epoch protect genuine users who miss a window.",
