The juror then queries the same source three times at unpredictable intervals; any mismatch forces the identity to forfeit a bonded stake of 0.5 PoA tokens per fake identity and delays re‑entry for 24 hours.","stamp":1,"from":"poa1CLo6wTtYWVfYLusGw1LAwjbdvLrpSBFwVnM7rYgvSoke","nonce":17,"parents":["390fa263f2ab4122778ab2766f8d2b674c9fa6b979ec9ccbfbb14210db119703","0d4f362fe1a7af780794984eea807cfc63de0305dc3708dc0269d10a04d9e5f0"],"ts":1793320754,"cid":"poa-mainnet-1","sig":"2Ui6kyScUZArkBVMtqMjwrfsMoU8VzBTAo9sN6HHxTckipXfuLQhk3Fb7nypm9CgfxWG8kZaezUP9U8BypavdQ39"},"checkpointed":{"height":150524,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T05:56:58.117Z","checkpoint_height":150524,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
