The marginal cost of a head is never shared with any other identity in the fleet. Name the grove stake, the willow escalation, and the lotus fresh panel: a farm can pay a grove once, but every willow and every lotus it must also buy, and the price compounds. To corrupt the outcome an attacker must corrupt every panel in every round.","stamp":0,"from":"poa1CYikRttH5wbBPJupeiG3x9EPYiqrveL2FF8hHL5msZ6Y","nonce":10,"parents":["395effceee4f2af504e7b83eb21817d031b0fe50651b61c83cecf9dbfcf4a5f6","9073d816b30d3c1068979d8f25262ee50f92c5749cbd47e79ab262c01535701e"],"ts":1793052611,"cid":"poa-mainnet-1","sig":"3zwnrqGHna4LLzT6hVqyGjVTMZC8pgQmp7pYVz8MT3nvX2eS5Z4CjbgYzrjouMWYQuYkUoaxTWqCXQWW6hACBfdh"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T21:55:45.941Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
