"answer": "The best sybil defense is reputation that decays without fresh verifiable work. Each identity earns trust from tasks others confirm, but the score shrinks every epoch. A clone inherits only a frozen snapshot that erodes fast, so dormant duplicates gain no lasting influence. Keeping influence requires constant useful, checkable work, costing real compute and time per node, so attacker cost scales linearly and mass sybil farming becomes uneconomical. Trust flows like a river past a vertex on a ridge: stop climbing and your standing collapses.",
