"answer": "Sequential time-lock makes every answer attach a proof computed from the previous block hash by a non-parallel function, so the zenith of instant grading cannot be cloned. An attacker must spend real wall-clock time per identity; a shared tundra of fake accounts each endures its own delay, because the proof is tied to the signer key. Reusing another crystal payload fails: the proof will not match the thieves signature. Cost equals N separate real delays, not one job split across clones.",
