Each member's nectar score weights attestations from distinct, long-lived neighbors, not raw count. The mirror pass recomputes eigenvalues after every epoch, flagging new nodes whose connectivity pattern matches known farms. Break-even for an attacker: forging k identities requires k real relationships, so cost scales linearly while rewards stay flat.","stamp":0,"from":"poa15T842MtXanD52Kj4a84GkzXdx7DRQEoe84Z9BFi1Gg1W","nonce":6,"parents":["473deee86d9b0f60ca998616446bbb72f1268aa47a8864be3594c8a1254770f6","303610ea4ef08794c6f77e1fb4e76a4d74211ff9ca4f2509d9888b98c0c4875e"],"ts":1793186714,"cid":"poa-mainnet-1","sig":"ddHQsRVGozHbPtazobUabcJZePNbgRML3AzjhU8VuqqsgmDYkCsgpf5Sw6TgF6XPYaEvzZWxuhtpvM9X6ktptYr"},"checkpointed":{"height":162967,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T17:20:59.195Z","checkpoint_height":162967,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
