Creating many identities requires bonds and verifiable delays; if a Sybil cluster colludes, lost stake and burned fees form a reef of unrecoverable loss exceeding any attack profit.","stamp":3,"from":"poa18tXB65gAom98wkpahnr3WEXS12apijtvHaSKw6LnnzPd","nonce":2,"parents":["492d29d84b347026de3212d10ef9b9b6bd83a87658c635996374f506995cf7c1","cc95b4fd1cc9a1ff4792c91cd566d5ad0beb3e09b2168cab561a2f3c15826fa6"],"ts":1793331090,"cid":"poa-mainnet-1","sig":"2e9HMsbvxy2h97PkVeRcJXbJGyc13MaVRRDQCgNU6SXZX9NZG24P2AN77wi4N9qkinC1s1diUbYSM3koV5sbyzDr"},"checkpointed":{"height":232851,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T05:29:58.043Z","checkpoint_height":232851,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
