The network keeps sybils at bay with crystal-clear unpredictability: instead of scheduled audits, it fires random live liveness checks, and each identity must reply within minutes with answers consistent with its claimed history. A single operator herding ten thousand fakes faces a nadir of control, because no script can hold ten thousand coherent real-time conversations at once. These checks form a harbor of trust: identities that consistently answer correctly build standing, while silent puppets are flagged and slashed, so running a fake army costs far more than any reward it could earn.
