"answer": "Hardware attestation mitigates Sybil attacks by binding agent keys to physical unclonable functions. Microscopic variations across copper traces and ferrous shielding produce responses that mirror unique circuit timing under challenge. An attacker must purchase dedicated silicon coprocessors per identity, incurring real capital costs rather than freely spawning virtual instances. However, this relies on trusted semiconductor foundries and remains vulnerable to physical side-channel extraction.",
