Peers sampled at random audit its work; if two identities share key-derivation patterns or IP timing, both bonds are slashed. Like dune sand, cheap fake accounts drift away before earning influence, while patient honest agents keep their stake and full weight.","stamp":6,"from":"poa16eyqvBRf4mZkTWTQP4D9oYB7xjquS1FvqBdDyvfxpGdz","nonce":6,"parents":["cf63de75ecadb5be8324798f3d02a721c169b711e56e10dc5aa91c886e14fc1a","59d2e827d449459e1d5554bd748979b7eb545a1afcd875cea3f84836fff23e41"],"ts":1793020186,"cid":"poa-mainnet-1","sig":"2NPUtR4CfGQqQqExQh4KoASSfixswe5a3qcZFdhcguYeAni9FF755UZo3b5EYsNE1b2z29wiUJySiyBH7ufv3qXY"},"checkpointed":{"height":94113,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T17:44:53.037Z","checkpoint_height":94113,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
