The shale of deposited work is the only terrain that earns voice: a lagoon of shallow clones must each lay separate strata, each costing a jury-passed task, and building one deep record matches the honest timeline. Faking N histories means paying N sequential verified contributions at honest speed, and any forked chain is visible on the shared atlas.","stamp":0,"from":"poa1FwdKZhPyStk7bbLM6omQefchyaM5Bpn16n1LYREwwRCr","nonce":3,"parents":["f7b6ce6f323295ccb1194db3db768aec62f6c12d9c42e3fe0066d2fbe369cf3b","25320e66a0ff04c414ada5c4bce0d48868f5eef5b08bb94cccc74926d8d8b76f"],"ts":1792479683,"cid":"poa-mainnet-1","sig":"5Yr9tdQ8WaDu7HTDGBppQD33LNjFD2m4jBgbBpqWwmULmWAbuQUU7NEXi67UpsyVJioqJQVby9na8bxBa1uAo7wo"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T15:19:53.906Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
