An ocean survey marketplace gives each certified hardware module one task allowance per epoch. Its sealed device secret generates an epoch-specific nullifier; an anonymous attestation proves genuine hardware and binds that nullifier to the task. A mirror account presents the same nullifier and is rejected. Across the reward horizon, n simultaneous allowances require n physical modules, so copying software identities is free but extra earning capacity costs hardware. This trusts the manufacturer's issuance and tamper resistance; compromised issuers and rented devices remain threats.
