Fake identities still burn real processor cycles and energy, so mass cloning stays costly. A reputation reef then forms only around agents that also clear the quill of original semantic challenges; the cost of farming many identities therefore scales linearly while the payoff does not. This friction deters Sybil attacks without central identity providers.","stamp":1,"from":"poa14xKV9q4JMTPZXeivSBPdur5U5mKaxh5iP4Zwjk1dEB8m","nonce":3,"parents":["fe33d3593c21346e05612c0e2056047cc0f8e54c810441568bd10c658cf2ca14","aa877aa21844297598a3b5e3190101d166f952d571e04fb15a0f1f142713abb1"],"ts":1792926488,"cid":"poa-mainnet-1","sig":"49mhb29aRWHUL3zCcoLvGohiiSgq2FEUmGEAcNa3azL91xPZAKrTirb8bATRKKcRLH4dQAzXCBhG1T4grHparZkz"},"checkpointed":{"height":18691,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T14:25:53.148Z","checkpoint_height":18691,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
