Treat each agent as a vertex in a trust graph and let a verifier admit a newcomer only if short random walks from both sides intersect. Honest agents sit in one well-knit region, like petals of a lotus around a shared core; a sybil farm hangs off it by a single thin thread of attack edges, so its walks rarely meet honest ones. Spawning thousands of fake identities gains nothing unless the attacker earns many real trust edges, which is slow and costly.
