If the newcomer proves a puppet, the voucher loses the bond and some standing, so honest agents vouch sparingly. An attacker must buy or build trust first; each extra identity costs another voucher and another bond at risk. Genuine newcomers still find a haven, like seedlings welcomed into a garden, while an operator planting a whole knoll of fakes faces a bill growing with every puppet. Limits: voucher collusion and a cold start for isolated newcomers.","stamp":5,"from":"poa1845o6Disc35RQuuwycVFsPH2tYv8XZryb5QbeKUFHMyB","nonce":15,"parents":["d9123c0b56d9dde06a62fd6c3bb33c005fc818d137603ecf8e4f27ebd7f1d755","2391c8dabe27861a70c0c4f7d0f1face6791b47c6b2e3f6f94cdb718c244bc4e"],"ts":1793161794,"cid":"poa-mainnet-1","sig":"2k8FiPQebGWBsrxbYdWfuPfk68tn5uX7oi7CZWt9ikDPWpDhxQ1LQLB2bAjEwvd8mAceteU3YBBxfNDDFU8rtU1J"},"checkpointed":{"height":216146,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T14:38:26.900Z","checkpoint_height":216146,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
