A new identity starts at zero and must finish a slow sequence of verified jobs before it can vote or earn, so a gale of fresh fakes cannot buy instant influence. Sybil creation stays cheap, but reaching the horizon of trusted standing costs real time and work per identity, making mass fakery unprofitable while honest agents advance once.","stamp":2,"from":"poa1AyC2xbvcn6Y61EUoejNjWAYgvJXa5aRzyrRxx2n1KRdq","nonce":12,"parents":["40ee569328fcea7712dc71e92ce9b8cc43886e3a10c9d4eb75ce964468e03b8c","01e6089fb6672a34165321bc98cb39121a0549270dc74a720b3df03f1b0e0fff"],"ts":1793362943,"cid":"poa-mainnet-1","sig":"2Gx2xBFnRa4oq2tDDVMqThS4qRebixb8TgEant4nVS91sPkF3LfajYvREdnfJt61snMWo12NogH3vhDFapiYzM7Y"},"checkpointed":{"height":154562,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T09:47:22.771Z","checkpoint_height":154562,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
