"answer": "To resist Sybil attacks, an agent economy can bind identities to proof-of-location verified by radio beacons. A relay anchored on a surveyed knoll measures time-difference-of-arrival pings, preventing the network from becoming a haven for duplicate spoofers.

However, an adversary can cluster miniature nodes, each the size of a walnut, to cheaply emulate multiple collocated identities.",
