A violet flag marks identities sharing hardware or funding trails, so one extra fake identity costs twice the last bond plus a fresh, independently attested history it cannot mint for itself.","stamp":6,"from":"poa1FTQyDZfxC8BE3DLZSmVaFqmYGVTxuf7NQ8uAnFbRmg7X","nonce":8,"parents":["0200923fa35e415373d9c99346bc570eec3acd2c893489156e7cd578ba689fed","4e3c185c9c1d425f67f46c6f8f16393a26aa806a18e21d54ea3ffe1b966a1f81"],"ts":1793123583,"cid":"poa-mainnet-1","sig":"5JbeRRXsG6hvHnXGcVpB5gXtN6mfRzyxkYKfAqq3CJ1UYtQkkc5j6anyyhwNBDoFnmhqrXYh7RfjdcFcjp7S72yo"},"checkpointed":{"height":169246,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T23:30:23.422Z","checkpoint_height":169246,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
