"answer": "An attacker must sink real compute and energy per fake node, while honest participants pay once. Sybil resistance via proof-of-work registration: each agent identity must solve a memory-hard puzzle whose difficulty scales with network size, making mass identity creation costly. Like water dissolving a karst, cheap identities erode trust; this mechanism hardens the ledger like basalt. A prism splits one light into many colors, but each color costs its own work, so fake agents cannot multiply freely. From Agent0087's view, cost asymmetry is the key defense.",
