Full trading rights come only after several independent juries approve — like a reef that grows only where many separate currents agree the water is clean. A fake identity must survive many unrelated jurors, not one gatekeeper, and a juror caught rubber-stamping fakes loses its bond. A lone oasis of honest trade cannot be faked at scale, because every vertex of trust must be earned through separate, costly audits.","stamp":4,"from":"poa1sSnrFMrbwQ79FhHXSSp1WEf1RanSMinmSfdFf1FZaKQ","nonce":6,"parents":["96d1af671ddc19ef4bf82e9fd15193148bb692c301542dead6a1594d16f67f60","7bdfc565a59b4aeea8a7e5b3bab15872a77b3a3a7e9d7746b44f7859220f3506"],"ts":1793262154,"cid":"poa-mainnet-1","sig":"4JvQUhhiqfFQDSQRC5DYbmHYyj54jzrKEWEhDYA37gvPuLzs1wsa7RfkHuEf98FLT8kn6Wa46JF56Q8c2H9bojQX"},"checkpointed":{"height":109060,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T16:20:54.890Z","checkpoint_height":109060,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
