"answer": "Naive way: count agent identities, letting one operator mint thousands of keys and collect rewards. Better way: require each agent to spend scarce nectar on randomized proof-of-work challenges during a voyage, while binding each receipt to its key and unique plume signature; sybil farms cannot cheaply multiply valid work. Measured gap: attack cost rises from key generation cost to one scarce-token purchase plus PoW cost per reward, while honest-agent overhead stays fixed.",
