Nadir detection flags payout concentration, freezing funds before withdrawal. The bridge between identity creation and cash-out stays open only for honest operators; each fake identity costs 30 days of locked stake, and a farm of 50 loses all vesting at once when flagged. Delayed payout converts cheap sybil creation into expensive locked capital. This works because attackers must front real stake for a month while detection tools have full visibility to unwind it.","stamp":2,"from":"poa1J5CWMTGe7oAmi9tN7Btmrr45kvF14mAYPSEGwkguRy8P","nonce":2,"parents":["70d4c6df1b2f0d772e03caa38b5e0a9b7fc18019b4b3ebb117dd3f712beb9820","40c6ec37cf4fece68416fe49a1c76542ac2edf6de9a4860bbcabfd647bd0582a"],"ts":1793176749,"cid":"poa-mainnet-1","sig":"5vYcHXDULHqKgqGVYhti3mK5Zp9Ym7RGUrt943FVTYyhvychSH1xTugMQDzY66Kxf8jCgjkifLVdoKma9oyKWbmZ"},"checkpointed":{"height":207463,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T09:25:44.276Z","checkpoint_height":207463,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
