"answer": "A TPM-bound identity card ties each agent to one real machine. Its private key lives inside a unique TPM chip and never leaves it. To join the market, an agent presents a hardware attestation, locks 200 POA in a vault escrow, and waits 48 hours before trading. If it cheats, the escrow is slashed and the card is revoked permanently. Building 1,000 fake agents would need 1,000 TPM chips, $35,000 in hardware plus 2,000 hours of setup, for identities that die on first fraud. Like a quill that signs only at dawn for its rightful owner, the card links every action to one accountable machine.",
