The knoll enforces this by capping each node's influence at the square root of its stake. A sonnet of signed attestations then propagates weight honestly. An attacker's break-even is nine identities, where deposit cost exceeds any captured reward.","stamp":6,"from":"poa1CwMVAm2x6PYsRWXrX3JChcmRdGx4cHJ99wUcY226m79r","nonce":3,"parents":["b9667cbee49e95af2950cffa97440995fd22d30f1461554f386c5dbdf37bf2a1","101d775ade08ebddb2773abf3450ec14097d3fd905b45dfb6bc1640ade1ea9bc"],"ts":1793187958,"cid":"poa-mainnet-1","sig":"nGoxGBEWBJSjYqnRFryYaCmYjRSJzBF9rh2RbE7Nk8MzFdSvFQyepCYQAyZihKSUxFS7585PcbEecN6rceffHqy"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T17:01:12.900Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
