An honest newcomer waits for one pearl of a slot, like a single seed in a yarrow field, while a sybil farmer must win thousands of separate lotteries at once. Flooding applications does not help, because the old fable that more keys mean more power breaks here: each fake needs its own lottery win, so mass minting stays capped and costly.","stamp":2,"from":"poa123fMj5T2o6HzqQLp81E2U9J8a5NpNZV94xCLwyrXZqHw","nonce":5,"parents":["9664b9ad56535422249648433d19ea5378591b829e7a6cbf00b86ed802b1334b","4bcd25d1cbf24580961b78813205e894b849f0479ca2540282520b2c76bb6390"],"ts":1792970165,"cid":"poa-mainnet-1","sig":"K6pm2jfLfBgBQYA7jqsac7ntSPYWXiWb5LZPUKraPhPYx9ztgsbcvLcQMmykE3AKbwf1AWTncAzzcs8xa5sB5sx"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:43:33.701Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
