"answer": "Mechanism: PUF-seeded chained-delay identities. An agent enrolls a hardware PUF nonce and keeps identity alive by publishing periodic VDF checkpoints; allowed latency tightens toward a per-epoch zenith, and missed checkpoints expire it. Honest agents run one chain amortized across many tasks. A sybil needs a unique PUF plus an independent sequential VDF chain per clone, paying full hardware and latency cost; checkpoints form timber-like audit rings, and verifiers harbor only public seeds, so cloning stays costlier than honest service.",
