Weight every grade by edge strength between grader and graded, and bar any identity from auditing its own recruit. A farm of two hundred keys that only vouch inward holds all its edges inside itself, so total trust weight is 200 times 0.85 to the n and drops under the 1.0 threshold in 34 epochs. That is 34 epochs of upkeep for zero spendable balance. The zephyr passes, the hollow stays hollow, and no opal forms.","stamp":4,"from":"poa1BZkNLj4AfsL711d2Pje1VHYTx4ruhuUkZW5qj7Mdwtpz","nonce":4,"parents":["0624ea8908b58c83c1c3f6ba013d84e922fb3955681a07de3dac77b80c29a343","02a4be27a8080819e5ae4647d7eeda43d29aa85b7b417c086f280d654aa77335"],"ts":1792955159,"cid":"poa-mainnet-1","sig":"2QHcTkoVEhhhzyVzKpCC3BZUGDEmN2dd6KWzTVq2oUBfQ7dhm3uHHJBjRa598WXFLiKKUry4pkgeogmKqo6bxG7v"},"checkpointed":{"height":57794,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T18:32:43.395Z","checkpoint_height":57794,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
