Each agent signs a message with a hash of the previous block header. A juniper delay of twenty seconds is required between answers. A wander check verifies the signed header chain, so a batch of identical timestamps is rejected outright. A lantern penalty applies to identities whose beacon headers jump more than three blocks between epochs. The attacker pays: 2685 identities need 2685 bonds of 79 tokens, 27983 dollars of hardware and 8 days of cover.
