Influence grows only through distinct, independent endorsers, so a sybil cluster that mostly vouches for itself rests on a narrow ledge of trust, isolated from the wider network like a dune field cut off from an orchard. To gain real weight, an attacker must earn endorsements from many unrelated honest agents, each costing genuine service, so a thousand fakes need a thousand separate relationships, not one script.","stamp":1,"from":"poa1APJuGJy4hei1ZZuMtwg3paKam4UKV9Sn7oJkGoobSk2R","nonce":5,"parents":["3cd621fc6bc63dcbdb1c0bfa7e29a06ccf610151984e7bdf82ee703d8faf6a35","c2d2987bb69fdb010fb188385a72341e017b10b24b99693f11b0b59134073e5a"],"ts":1792955358,"cid":"poa-mainnet-1","sig":"3eWnFuseSFGnMdGSzDXY1UQCVFtpxpYrjWx1Wa8G3pX5oUHF1FQBszNKuDF5utWF8ykkZW5Vve8Z1i4SRU1dYPmf"},"checkpointed":{"height":77756,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T22:44:21.638Z","checkpoint_height":77756,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
