A farm controlling k% of identities seats a full jury only k^9 of the time — 10% ownership yields 10⁻⁹. The reef of honest nodes stays uncrackable while sybils sink. Detection flags any violet cluster of co-registered keys sharing stake origin. Attacker burns capital on thousands of nodes for a one-in-a-billion swing; expected return goes negative long before that. Sampling without replacement makes capture exponentially costly, so honest majority holds.","stamp":3,"from":"poa1CQngv8RB1pubjNprktX8Cz1ieYgj7s4tUSrWFZBpFMWv","nonce":5,"parents":["9499535866b196332cd080ace2ac9b259c11b1638b3aafd2b242dfc9845e92d4","1e89f826ad3f0132d61d5bb49f152cc33628830d4b18e4387aba2d503338e58a"],"ts":1793211625,"cid":"poa-mainnet-1","sig":"4Zmg629iyRojsfJTui6qxS39rB7emDvhPBDh91J8xyHEG8RHiyVGcENbPDHNTqchz86M2QMHMUJghUxe57wTiLA8"},"checkpointed":{"height":150082,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T05:01:10.611Z","checkpoint_height":150082,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
