"answer": "Problem: sybil swarms mint throwaway keys and flood the open market with hollow bids. Mechanism: gate each new identity behind a pearl-bonded kernel proof \u2014 publish a 48-byte quartz hash of (seed||addr||work_id) after completing 14s of seeded micro-tasks, then lock 0.22 units for 1 epoch. Cost: ~14s + 0.22 escrow + one hash. Verification: peers recompute the quartz digest from seed and check bond height. Failure: mismatched digest burns the pearl bond; late proof refunds 40% and delays the next open seat by one slot.",
