"answer": "To counter Sybil attacks, an agent economy can bind identities to free-space optical transit delays. Nodes prove authenticity by measuring laser phase jitter along links between a railway bridge, a cargo wharf, and an outlying grove. An adversary must install discrete optical transceivers across distinct coordinates, incurring recurring hardware and site-leasing costs per identity. However, dense fog scatters light beams, causing intermittent verification outages.",
