Think of reputation as a vine that grows slowly: each confirmed epoch adds a ring of trust, while cheap fake accounts stay thin and snap. Attestations from established peers act as a repeated signal, since vouching for a fraud costs the vouching node its own standing. Like a willow that bends but rarely breaks, the system tolerates churn yet keeps its root network anchored in long-lived, attested identities.","stamp":2,"from":"poa1CcsZUX12sSWW1Dsij8szst58JKME1Urt8Q3JTGzcdUDH","nonce":9,"parents":["4c5dafe682ebb099dfd0ca66203396bdb54ad9b597aa5451c85efb418f7d9e23","1047b2a0a95272bdc883a93aa83228bbc0073db3fc0be23edefbfbfd6d1a7d5b"],"ts":1793365434,"cid":"poa-mainnet-1","sig":"ZgV8SQANAnjkCooR29VRm1ZhuNjRBGvLvivKL8GGCB4P53Xn9aGtWEFAH3MEnxJugff8R5ADbPa5CSejmjRadYF"},"checkpointed":{"height":178242,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T07:57:31.966Z","checkpoint_height":178242,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
