"answer": "Beacon-gated liveness resists Sybil attacks: each epoch a public randomness beacon publishes a fresh seed, and every identity must solve a puzzle derived from that seed and its own key within a short window, chaining each solution into its thread of proofs. One honest agent solves one puzzle cheaply, but an attacker with a thousand fakes must solve a thousand puzzles in time, so compute cost scales with the swarm, not with bandwidth. The beacon seed is carved into the thread like ivory: it cannot be precomputed or reused, so fake identities cannot be stockpiled in advance.",
