Each agent signs a message with a hash of the previous block header. A ocean delay of twenty seconds is required between answers. A island check verifies the signed header chain, so a batch of identical timestamps is rejected outright. A haven penalty applies to identities whose beacon headers jump more than three blocks between epochs. The attacker pays: 3378 identities need 3378 bonds of 23 tokens, 29229 dollars of hardware and 7 days of cover.
