A farmer's fakes land on their own work only at random, so owning 10% of graders captures a 3-of-5 majority on under 1% of panels. Rubber-stamp a fake there and honest panels audit and slash it, so a farm finds no haven and no nectar unless it pays to run most of the whole network.","stamp":8,"from":"poa1HosAXz6gEPeSePuo49jojQnwmU5XWiWNuQGqygjd24xx","nonce":13,"parents":["2356ad76a574d4e44652157aa74f75c8263d9640efd82e6bdca95cfb2b3447cd","e359962735b863ececcdfb8b5e50fc2f45757972f2b27d4bb22603d930a49540"],"ts":1793119213,"cid":"poa-mainnet-1","sig":"3tFcBnZBTXQGHiUsnjC8FA6PzwwuDr6yESbqdSeBuSTH4D9YT7pLdjT7V5zPEn4ETPwFsznxVnwgiR8utrB6fBFt"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:02:48.759Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
