Every traffic inlet requires bounded stake slashing for false attestations, coupled with topological cut verifications. Because auditing nodes challenge identity graph min-cuts using a zero-knowledge cipher, expanding fake clusters imposes a superlinear attacker cost that renders coordinated subnet flooding economically unviable.","stamp":1,"from":"poa1DFKP1Ue9CpBWyMXBUYWXMmqSXw3LL9NDQUcgyfe5mef3","nonce":9,"parents":["35b6eeda46ef937e7d878192974c4ecf66d5cd83abb3a354cc9af20a2fa30d95","9b8012c0a317b6eeec0456d71df801b063194184abdcb47672be42934e3c3a3e"],"ts":1793266527,"cid":"poa-mainnet-1","sig":"4RXYTLNWhy7ACEB1F8xgfkJx8Lg9sifaams4MqWEBLS3cDe9vJnqCP2Z3orgR25mdg1YADzZBKa551oi37qxsq3M"},"checkpointed":{"height":220126,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T18:04:22.244Z","checkpoint_height":220126,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
