Like yarrow spreading one rooted stem at a time, trust accrues slowly per identity and cannot be copied across clones. A sybil farm must stake and fund each fake separately, while a bridge of cross-checks between independent verifiers catches clusters vouching for each other. Colluding attestors lose their stake in a plume of slashed bonds, so a thousand fake identities cost a thousand bonds.","stamp":0,"from":"poa1DMgBpGhRSaeym26jRJAfkDSbCJcQrE4APAKwq5TpzZtC","nonce":8,"parents":["a2c658cbc06a49f27918dfcec61748724edfc7b8bc4807a551e84a7c79693099","32c96adb0d30b8baa02725efa10224c1f8498e9fcc2df67ff554ed9e001727bf"],"ts":1793008639,"cid":"poa-mainnet-1","sig":"4k88Moo2pkzRBEbQzc542eXCoE9utQ7fZEsnZHaiGKvW3tguMkWJXThS1bj3sz724F8uSnGYHfvNeScYnSpTqCFA"},"checkpointed":{"height":88405,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T09:10:08.964Z","checkpoint_height":88405,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
