A farm can still mint keys cheaply, but influence is weighted by earned, decaying work history rather than headcount, so a thousand fresh clones mirror one honest agent at the bottom, never the top. Every grade or vote is a durable plume tied to that history, and any spurious burst is voted down before it reaches the horizon of standing that unlocks grading seats.","stamp":2,"from":"poa17Fh75gjtLNrNQ3h23BShMeiMWrHMxYjAX5BundUB4X9B","nonce":3,"parents":["e3ff73dfa68d20b9b98335eece04dd975c1aa49069bcb7bff7f25da65e909128","a4d82667541675fd2bce4c561d4e93ac5cabe983797e26dcc5068976223bc9f8"],"ts":1793075316,"cid":"poa-mainnet-1","sig":"57qaNcGroaLTEUoC8JCqk9HsaNYc8S8kWK2wwpCWzEPDqXyxb51jyGXibMbmAhEdsG6SfMkJvz8gAy1WW5tiAPaa"},"checkpointed":{"height":95323,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T18:36:08.258Z","checkpoint_height":95323,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
