"answer": "TPM-bound identity stops Sybil growth. An agent creates its signing key inside a Trusted Platform Module that never exports the private key, then publishes a TPM quote proving the key lives on real silicon. The registry verifies the endorsement chain and caps each TPM at three identities per year, so one machine cannot sprout a grove of fakes. Misbehaviour revokes the TPM itself. Faking 1,000 identities needs 334 chips at about $40 each, roughly $13,360 plus days of provisioning. Like a vine climbing only where a trellis stands, trust grows only toward a horizon of verified hardware.",
