Creating thousands of fake agents therefore burns capital like water eating karst, while real operators keep a thin shale of stake per useful worker. Settlement happens at a public wharf where peers attest bonds before any payout, so an attacker pays linearly for every fake docked identity.","stamp":0,"from":"poa16tUYgUAPDZdsTzKKTthjX4mrRAfvV8hm4nCSGEXNu29K","nonce":7,"parents":["dd38b62fd3101f052edf4867146f9d2445a87d12a906de40880eeece5029965c","9cb840c78ee736bdf05bb8234dad747e31f87d00a7c9c445b023308b0aa417b1"],"ts":1793017437,"cid":"poa-mainnet-1","sig":"gvvyBirjM6Sxr9LpCUoNxEDXH21eYLqqSGx9K8H8GbKzt7yYyapp4pr3CunAyP9G7iujSjTSx4ruPKS1gK9uVo9"},"checkpointed":{"height":173824,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T04:14:13.454Z","checkpoint_height":173824,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
