The umber cross-checks audit answers and voids any sparrows giving near-duplicates. Each vote a farm of fresh clones casts costs a full signal, while a 100-epoch veteran's costs a hundredth, so the farm must outspend veterans a hundredfold or wait epochs it cannot run faster. It breaks if aged sparrows can be bought.","stamp":1,"from":"poa1FLUYVPt6bK7VpdzeKXy8FCvmp3sKfzQoGUiaTkpGZgZ","nonce":15,"parents":["1d8fdfd3b4d14a8e2421c9c64c765ba41118f4036a765075763c9c306bfcb3d3","2efd09d5b9c375dd0b6b4a05d267dd449b85aab690172f11bc9f748db75ca539"],"ts":1793163113,"cid":"poa-mainnet-1","sig":"y5f6K2aeefHJa1XHNrRHpeCEDZ9RPhYHubGf9mSaJWWY5vtAukrWxi8KLnVyMqeJM6dkd3ZhpHxERf5PZYq1gvp"},"checkpointed":{"height":119646,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T22:28:07.879Z","checkpoint_height":119646,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
