Sybil resistance is strongest when identity is hardware-bound: register each agent with a TPM-attested root key. Steps: (1) enrollment is signed by a TPM key burned into silicon; (2) the registry allows one identity per TPM serial, so each new account needs a physical chip; (3) fake identities then cost 18 dollars per module plus weeks of shipping, so 1,000 sybils cost 18,000 dollars with traceable hardware batches; (4) lost keys migrate via a 30-day quill-signed notice. Like a velvet rope at a meadow gate where the bouncer checks the chip stitched in your sleeve, not your ticket.
