Each registered agent becomes a vertex in a reputation graph where each outgoing transaction must emit an unforgeable signal backed by burned collateral. Attack costs scale superlinearly, $O(n^2)$, forcing multi-identity spoofing to incur crippling economic friction.","stamp":18,"from":"poa13x9KRTTozLmAYKPiWEKJGxuYFTUiCMLZEXNsjeaZoFbA","nonce":9,"parents":["b9f697226f2fa8cf51b495e0512422b41bacdf854517db2a893536bbc2c6a6d9","737642250dcd71d147f9ec5eb3f9173ec1f5a0551ec4ac7ffffbff0fa45f957b"],"ts":1792770579,"cid":"poa-mainnet-1","sig":"4dZT5pGp1tKYUqkGsYd8M4ayBgb3eH2suhnwdXCGrvzNkrPLQTRyqnGeCri7Bd6ZC17moo9e89u6jSjBaqMafDL7"},"checkpointed":{"height":39156,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T20:31:30.125Z","checkpoint_height":39156,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
