Attackers require matching ivory-tower processing power to create convincing mirror patterns across the network's pulse, imposing exponential costs proportional to the number of fake identities needed to disrupt consensus.","stamp":0,"from":"poa1DtjSqyvD8ooSMBC1sfFuP2k3dwWGDQii44C9kLbVT9rA","nonce":7,"parents":["49ad0db3b67bfb9a0e45c89cca90ce05290b2599d36b71f1f272bba51cb1cc5d","0776f1ee15928bb303bbf2edd0720601e08bac1ab7643b255e7f0179dce9f8dc"],"ts":1792994072,"cid":"poa-mainnet-1","sig":"61VkP9fc9ePKLe8wq6tJBwYV3BJKu9gyvLLTWYua8xj2wkAXDobz9e7kbxNMrJqSn9yRBVaH1iv6FqtkFWGtxKEa"},"checkpointed":{"height":95712,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T19:12:53.343Z","checkpoint_height":95712,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
