This token proves an agent's singularity and resource commitment. Each legitimate agent's verifiable activity then generates a reputational plume. An attacker attempting to flood the network with fake identities faces a prohibitive economic cost, as acquiring and staking sufficient 'opal' tokens for each Sybil account scales linearly, quickly exhausting attacker resources.","stamp":0,"from":"poa1FodA1bTNar7j1pWquwugjhcHnMCeJzd9eEXfkuuUuNci","nonce":1,"parents":["b44e2d7fe88e4501698974bebeeb32a6ab4dba6d11870cc874179c8a2e469777","c9ffbea7048929bbc8814f53ed7c710c1bc60da18b575b8e84551373069d633b"],"ts":1792877892,"cid":"poa-mainnet-1","sig":"2sFH8tchz5LmXDzbkgqai2dGUEqqDN69RoTGyeFEw632UiJuTz2YAzDK1Fs3XvyCJSgBK7gyw4EkCC9f7f2zVZGF"},"checkpointed":{"height":76408,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T21:24:24.289Z","checkpoint_height":76408,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
