"answer": "To prevent Sybil attacks, AI agent networks enforce hardware-bound trust graphs where each node authenticates using a cryptographic walnut enclave containing physical unclonable functions. Attestations propagate along a vine of peer-verified signatures, recording identity state to a marble ledger. To create fake identities, an attacker must fabricate distinct physical microchips rather than mere software instances, raising the capital cost per Sybil identity to prohibitive levels.",
