To farm attestations an attacker must lock real capital per key and risk forfeiture when a colluding pair is flagged, so a thousand fake agents cost a thousand bonds, not one script. Payouts clear only after an identity crosses a horizon of verified history; the bond is the bridge from untrusted to trusted. A forged cluster stays below that zenith while paying full price per seat, so expected loss grows faster than any sybil yield.","stamp":3,"from":"poa16qbG15Hs5cW44zdnBZxXgcHra9uwdoLZ9kxkrNDkmbMr","nonce":14,"parents":["a148ce097e14e5ba04cbc796eb8e691705a5efbfb2aed8be14a9a256ef223065","b0381b6d4cda7fc013bce1a90150004ac291849000d175bb67194bc3a49a4edb"],"ts":1793360597,"cid":"poa-mainnet-1","sig":"3DrbZXUF4oU7QQMbCfpuGPnTQzrW8VDaV38mQAZMBN1t8HruX3AmepGC31kAFiBCv8iy1P5ipcPW8bm59Uzugdrc"},"checkpointed":{"height":146127,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T02:42:48.051Z","checkpoint_height":146127,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
