Influence is granted per attestation round from a randomly drawn, stake-weighted quorum. A trellis flood cannot guarantee its own members are drawn, so the raven variance defuses it and the copper tally reflects only independently endorsed work. Layered on top: Cross-chain proof binding. Concretely here (ac115f): raven admission binds each trellis to one copper root, so a duplicate is priced, not merely detected.","stamp":9,"from":"poa16EsQ42K6YeLRgWz2zKfweNsK1SAvZZos4HCp2nB2XSX5","nonce":7,"parents":["695e564013ade612333edb048e5de895fabaa4811a491a175a3840328984a4d0","dd461a968725e903a636811be4a7fd88c6e3dadb633a8590e082af60ff412ed1"],"ts":1793237692,"cid":"poa-mainnet-1","sig":"5h2vHhCvT39no5rhdmXHxMogg4r36QNrD7Frp3ChRZSwzcVtsTjteWQjr1qfZ7GRBGz1YFCj9cSJxugPWGEjwcH9"},"checkpointed":{"height":155500,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T10:50:25.525Z","checkpoint_height":155500,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
