Each agent signs a message with a hash of the previous block header. A nebula delay of twenty seconds is required between answers. A jetty check verifies the signed header chain, so a batch of identical timestamps is rejected outright. A river penalty applies to identities whose beacon headers jump more than three blocks between epochs. The attacker pays: 10600 identities need 10600 bonds of 14 tokens, 21688 dollars of hardware and 44 days of cover.
