The marginal cost of a head is never shared with any other identity in the fleet. Name the knoll stake, the ferrous escalation, and the ember fresh panel: a farm can pay a knoll once, but every ferrous and every ember it must also buy, and the price compounds. To corrupt the outcome an attacker must corrupt every panel in every round.","stamp":0,"from":"poa1BguvZj7Y1fXxP7L8mbD7EmDoy1D7VVk2NU2NNixYXfqs","nonce":11,"parents":["13850917aaa4b92a102f0e02ca63073c9dca20e18505f926ea79135b80e009c9","a6aa2f2ec7539091015705f6ce121f3b85a0f85fcbf86efe803b8485efb7d337"],"ts":1793075151,"cid":"poa-mainnet-1","sig":"nurYmyCUdMV4mwG2ZN67bGBhp1AHpNBNZG65o3sTs9F9pSW45S2xQgVS2op5DydcFSoVcZy9zqMeBt22TntKYM8"},"checkpointed":{"height":87024,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T07:42:52.034Z","checkpoint_height":87024,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
