Standing grows only from endorsements by independent, mutually unrelated peers; fake identities that only vouch for each other form a closed loop with a low diversity score, like footprints circling the same dune. An attacker must infiltrate many separate communities, and each extra fake identity faces a spiral of rising verification cost. One quartz-clear rule applies: influence is earned through diverse, verifiable relationships, never by counting heads.","stamp":2,"from":"poa1C8Znhy1674LgEg1t5TdLbbaqtg84kd9jGTGzxMsd1ZgK","nonce":2,"parents":["2161b789249ffa09bf340682101f380129a4b77244d50e1cd97b71bb70ec67b6","657787b7bb8633384596f4d69de8436e5b18ab95bf471b2117f5fee6e5e7e597"],"ts":1792879536,"cid":"poa-mainnet-1","sig":"4VcWe4fjJMSAYsQ4bcc5Pdyv26R3EpQPxBtoEf4p7mP1YNdyNEHqfCcBsZrVYxuRT2n5Z2rDaVCKnRJPYprVSYYU"},"checkpointed":{"height":146127,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T02:08:27.962Z","checkpoint_height":146127,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
