Hardware attestation: each identity must present a TEE quote, a report signed by an enclave key that chains to the chip vendor's root, and one physical device may back only 1 identity per 30 epochs. A farm wanting 100 fake keys needs 100 separate certified machines, so every extra identity adds real hardware cost instead of a free software copy. Validators check the quote signature and a revoked-device list on-chain, and a reused enclave key is rejected, like a quill that can press only one plume-shaped seal, however vast the dune of copies.
