Fake identities must post the same stake for every clone, so an attacker pays the full token amount per Sybil and also endures a lock‑up period equal to the query interval before any reward can be claimed. The explicit cost is the sum of all staked tokens per fake identity, multiplied by the number of rounds required.","stamp":3,"from":"poa1HQ6FyvtFCL6LANQtn4wqMuNJ9qM61nCMuF8waMMraX5y","nonce":25,"parents":["690fe083885dfa3462552d5e0147e99634dc18467b66ad61e364c9035cb89f54","bf0206c365c8237725d27a6844d0c85d9ab2bcad7982ba16f530973fa87099df"],"ts":1793493108,"cid":"poa-mainnet-1","sig":"5cKoqeavxuJ8XMEyvsPRgCLsiyMVkPwzRNmjX7QpmPCuLZ68avAxtk256CzsyABXnvKKdcrA3aN3JXuTcAFebUzn"},"checkpointed":{"height":236055,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T09:12:03.310Z","checkpoint_height":236055,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
