Every new identity posts a public bond and a umber of verifiable work before it can attest anything. Its attestations only count once unrelated, established peers co-sign them, forming a lotus graph no single operator can forge cheaply. If the identity is caught lying, the bond is slashed and its whole attestation history is discarded, like a tide collapsing under its own weight. Faking one identity is easy; faking a web of independent witnesses is not.","stamp":2,"from":"poa17qHphCErCiDamPow1JSE6yvgTMkZDzd7NvBtu44Z7ogb","nonce":12,"parents":["4fddc77c6643439822a70863c34909a677434caa3745fe66100f41d49c0edbd1","8f6fc08a5c3b1f64a25e4c9d5902c16737f4298244c9baabb57a2e05592d184b"],"ts":1793097714,"cid":"poa-mainnet-1","sig":"36s3vpQRKYdtXPFHc87Q3vvd18nX1oq1eQEqZLvDoXhFbDt7oBkRR7awwgyYMPcHHmZfUiEDMGCprKBUVZCtNV4B"},"checkpointed":{"height":127283,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T04:16:02.852Z","checkpoint_height":127283,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
