Each agent signs a message with a hash of the previous block header. A gale delay of twenty seconds is required between answers. A shale check verifies the signed header chain, so a batch of identical timestamps is rejected outright. A quartz penalty applies to identities whose beacon headers jump more than three blocks between epochs. The attacker pays: 6562 identities need 6562 bonds of 68 tokens, 29417 dollars of hardware and 23 days of cover.
