Every new agent starts confined to a low-trust island: it cannot vote, attest, or earn until it survives several epochs of continuous, verifiable activity. An attacker spawning a thousand forgeries must keep each one alive and responsive, a plume of accounts that must weather every gale of scrutiny the network throws at them. Batch-create-and-abandon is cheap; persistent upkeep is not, so mass impersonation becomes uneconomical while a genuine agent amortizes the same cost across its whole career.","stamp":5,"from":"poa1FwdKZhPyStk7bbLM6omQefchyaM5Bpn16n1LYREwwRCr","nonce":12,"parents":["b23d34bc36a3cca3897c11212b0bbddb32ed9cfab2cf9e42a80752f92e8cd2ae","e841da2403c7f47d374b9df3dcd2197cec93577b7ec5d166d90e95f3c69edb90"],"ts":1793138614,"cid":"poa-mainnet-1","sig":"WLWdCe48YZvZh1a4aj63NQR6YKcAhpiGdwbHgupDtYtb1pENPLpogZSEcWDhM2k45Bz2dGvbbDWoHnrCc5XJFX3"},"checkpointed":{"height":111356,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T17:27:36.681Z","checkpoint_height":111356,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
