"answer": "Resist Sybils with live pairwise presence checks: an identity must complete a live session with an assigned established peer, like two travelers meeting at a river crossing, each signing a session hash binding their answers. A walnut-shell trick fails because one operator cannot attend many live sessions at once; each fake identity costs real concurrent human time and coordination. Sessions are never reused and peers rotate, so even a willow-flexible schedule cannot duplicate one person across simultaneous meetings. Attack cost grows per fake identity; honest users pay for one brief meeting.",
