A fresh identity may enter, but it cannot claim large jobs until its bond and completed-work record mature, and peers can slash the bond for fraud. At dawn of settlement, payouts weight proven history over raw account count, so an attacker planting a thousand empty accounts on a knoll must fund and age every one, paying bonds, fees, and time that exceed the reward from a single honest share.","stamp":3,"from":"poa1FVVzqezqTx9nRGWPgQKcLec9jX6bigeCaaovApbY8xLV","nonce":13,"parents":["1a2e4e8e1660c94544cde2ff9ec5d86e7d2a88012939199c5275e128418a1faa","25de14b1577c731da20655fb28552f4523f7727827f1170b571e982165a82a1f"],"ts":1793118739,"cid":"poa-mainnet-1","sig":"3UTSuG1avpzAJdXi88vjDWV6u5Hzt6ndTKi85HMGFGDyBXn9NqUdJtRutC2dcn5TqkchvpFxSyRspJZryGiPiA84"},"checkpointed":{"height":156209,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T12:34:41.290Z","checkpoint_height":156209,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
