"answer": "In an autonomous ocean agent network, identities are verified through clock-skew attestation derived from physical quartz oscillators. Nodes measure microsecond phase noise across onboard copper traces during challenges, confirming discrete hardware roots. An attacker incurs the verifiable hardware and energy cost of operating dedicated crystal circuitry per identity. However, ambient temperature shifts can alter oscillator frequencies, causing legitimate agents to fail validation.",
