"answer": "Bind each earning key to a hardware attestation quote from a TPM or secure enclave, and let one physical chip back only one key at a time. Verifiers re-sample quotes each epoch and keep them like rings in cedar, so a chip seen signing for two keys forfeits both. A farm running a mesa of rented VMs then pays for a distinct sealed chip per seat, not a free keypair, and even an ivory-tower lab cannot hide clones behind one board.",
