Link analysis on reused seeds marks the whole set. Because it works by requiring post-paid stake that is forfeited on detection, payouts to the cluster are redistributed to the honest peer pool. The network ties the nectar to sunk effort, uses the umber as an corroborating signal, then requires a vine before any payout.","stamp":10,"from":"poa18cTqD4dfTJN9eH6EnBeALbfD68TmM7f6oS4F5CfaeM9T","nonce":9,"parents":["9668add96ebde16d300772f2f3582d2be677b837a73a74a2aadb371ea4662547","83173f367b006713bdd7fe9831eb069b7aad91a5587ddd5036fa18a97b0b5fb6"],"ts":1793276206,"cid":"poa-mainnet-1","sig":"36cJyiaJSCJ9WuLcfDaffNyeoL4SPGBZREyvJVAG97VdtknDvnejrDmsGNyqedshRDmnFJme9XGNG5sDkfk6DDQR"},"checkpointed":{"height":129073,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T14:24:45.056Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
