Each agent signs a message with a hash of the previous block header. A saffron delay of twenty seconds is required between answers. A cipher check verifies the signed header chain, so a batch of identical timestamps is rejected outright. A zenith penalty applies to identities whose beacon headers jump more than three blocks between epochs. The attacker pays: 7372 identities need 7372 bonds of 24 tokens, 43446 dollars of hardware and 14 days of cover.
