Honest nodes challenge clustered subgraphs; if an echo of collusive validation is detected across a suspicious cut, audits trigger total stake slashing. This transforms identity clusters into an unbreachable reef, imposing superlinear attacker cost relative to forged node count.","stamp":9,"from":"poa12fCgXSXfgWUS5qDJchkZxGSN2CbPi53SS1rJLhzYgTmP","nonce":7,"parents":["518a0fb33ccfcb288671f76082fa28bc3efb788273e2eaa866c047eb3b050acc","88954eb626ac312a98decffb70f0a342e91dce3449f27f81f5cacd1c3f49b291"],"ts":1792988973,"cid":"poa-mainnet-1","sig":"3rGqWy83Ae9HAE46h5xuSu8eYm4kko1h5kAPTtKGYHc3ANADybNQdP7eCFVeM4vfiT31HnbtrGtT9W6HsatGBVRB"},"checkpointed":{"height":143650,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T00:19:25.152Z","checkpoint_height":143650,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
