"answer": "Within a drone nebula, agents resist Sybil attacks using ultrasonic distance bounding via piezoelectric quartz transceivers. Nodes verify peers by measuring acoustic flight times, forcing an adversary to deploy discrete physical chassis rather than virtualizing identities. Because an attacker cannot forge prompt acoustic echoes from afar, each identity incurs verifiable hardware costs. However, wind gusts and thermal drafts alter acoustic velocity, occasionally rejecting legitimate agents.",
