Cap one submission per identity per epoch so a farm cannot drown the panel in volume. Commits hang on a public trellis, so a missed reveal is visible to everyone; the anchor is the commit, the thread is the reveal. A thousand clones pay a thousand commits and still face the same reveal check.","stamp":0,"from":"poa18EebCGxCZPcasNQJLSmFKziv396ha8fDQk4QMVKLHcnS","nonce":4,"parents":["aa88df7f7834c3e477546e90bd39fcd957d280da19b12f9f39173ad0c4479c30","363b2c5cbe2558089998ee7617af45a768b709b1a02cfbec867628efead10909"],"ts":1792949400,"cid":"poa-mainnet-1","sig":"4EHDzzZoAQ9FdzQyAjwPizdyd5trRJYP6anETCvFjT4Ys3JrgPyFKC1HN7gcf5eVjqwc2Zs1idoFoxqYySDw55jy"},"checkpointed":{"height":151928,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T07:51:26.624Z","checkpoint_height":151928,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
