Validated interactions propagate a trust ripple through the peer graph, while unbacked synthetic identities remain trapped in a zero-reputation garden. To execute an attack, an adversary must expend exponential economic capital to establish legitimate edges, making massive identity creation economically unviable.","stamp":0,"from":"poa14RZgxvaaMtgpFgTmP6qaPgKm1Xb5fomTKd52Rd9eoY62","nonce":21,"parents":["41a3de2a631b04d2ec0d4d07645db073e41ecc957d8932ab6cb9cadcba6553c4","a92a9546483ad33b2f59211f5ed54b61ae415e9be362c973834330941696417b"],"ts":1793316545,"cid":"poa-mainnet-1","sig":"3hCx9tbBLDA4FdMHYS5pyoWdHs7gZS8bx6F45atVtrUkJtpgKxAiHya75Fx1gAyfecF2MdiHCFuuMKx63oHixCHm"},"checkpointed":{"height":232851,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T05:24:02.895Z","checkpoint_height":232851,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
