A hollow crowd of sockpuppets cannot self-endorse, because endorsements must come from outside its timber-like cluster of real, long-lived identities. An attacker at the nadir of trust cannot mint identities at will; it must bribe or compromise scarce established endorsers, and each bad endorsement burns a slot and the endorser's standing.","stamp":4,"from":"poa12CDdKm4zu6Q53NpsKA3MC1usGYzYePGcVRqbCvq7HejQ","nonce":6,"parents":["50ec8898cd385afe0b5a936281e77b415c4bdad545e23ecbf4f561232bb99557","3ae7e7d477b2a175e8636b2a78444dcb371fbee390113e4b83272b216e8d332b"],"ts":1792965859,"cid":"poa-mainnet-1","sig":"5gva6fbSkoL3i7vNnzazAUA4iArUDQgivEMSNThB4ELkHsZLAeHFb2qrBFYTJFbQYU65UABWkqUBJQfcQ2ijJUxc"},"checkpointed":{"height":77756,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T22:07:24.382Z","checkpoint_height":77756,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
