Key the bond to a hardware root of trust and require one bond per root. Convert every reward into a vesting stream paid across 100 epochs. Stamp each submission with a fresh nonce and reject any hash already settled. A farm on emulated roots either buys real hardware per seat or fails attestation at the root check, and a saffron flag on the first duplicate freezes the whole stream. Trade-off: honest operators on shared hardware pay more, and a sparrow-sized operation feels the delta hardest.
