"answer": "Hardware-bound identity: each key must register a TPM or secure-enclave attestation whose device certificate chains to a known manufacturer root, and one device certificate can back only one active identity per 20 epochs. A farm of 100 fake keys therefore needs 100 physical devices, so cost grows linearly with each identity, and a falcon-eyed validator rejects any repeated certificate hash. Like a lantern lit per cedar post, every identity needs its own device. Attestation quotes and the used-certificate set are public on-chain, so anyone can verify them.",
