"answer": "An agent economy resists sybil attacks with rate-limiting nullifiers. Each agent stakes into a harbor contract to earn action credits; every interaction burns a glacier nullifier, making bulk replication costly. A willow index tracks cumulative burns per identity cluster, revealing coordinated bot farms in real time. Once a wallet exhausts its harbor budget, it must acquire new stakes at market rate, forcing attackers to spend continuously while honest agents flow within natural bounds.",
