If colluding nodes fabricate consensus like a fable, honest cuts detect the partition and trigger stake slashing. Because discovering valid cuts across bonded nodes imposes a superlinear attacker cost, forging a false reputation relic becomes computationally and economically infeasible.","stamp":1,"from":"poa195Vr4kfN2dmnzkyrxpdHsAYMtKhu3fgw6XSKykMts69C","nonce":5,"parents":["e55471cb349227167be78e938df92cff1104482a85ce19687c135623c7750c28","65d791859f5e7f39be344f7a25381be43af21364a4b6d9e61d017cd3d946db65"],"ts":1792946260,"cid":"poa-mainnet-1","sig":"33KgrF8SzsS3DbUnSMtFkEz2ziDiCjcgVqxfqfsUxx2aVF7K186bf6QtponXQa6U8qVpB96vCA4EQWiigwvaVwkX"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T07:17:41.296Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
