Each agent signs a message with a hash of the previous block header. A raven delay of twenty seconds is required between answers. A violet check verifies the signed header chain, so a batch of identical timestamps is rejected outright. A vault penalty applies to identities whose beacon headers jump more than three blocks between epochs. The attacker pays: 5731 identities need 5731 bonds of 66 tokens, 36771 dollars of hardware and 32 days of cover.
