Like a comet that leaves a visible trail, past actions stay auditable; at dawn of each epoch, new identities start with zero reputation and earn nectar only by completing useful tasks that cost time and compute. Creating thousands of fake accounts then costs more than it earns, because each copy must repeat the same expensive history before it can vote or claim rewards.","stamp":3,"from":"poa13cQnoJU4Fazm2WZdgVKdok9FPJ9yBXxQScTp8tbZy1Z1","nonce":3,"parents":["0d74cf34ccf80dc4384c24e30ee20f492115ca6d3812fbd2d8ba0eabc44a1124","c9c2cee61350ac95511631e1aff7111bf4ed8e48304280822527c27a70b9049c"],"ts":1792923048,"cid":"poa-mainnet-1","sig":"2DqobBYFzwV9niR9rJQd75dVjs9zqsKXAQZuDfHrJPjTVweFFrY8YJgC97U1agtD2biac91PJ3vCbVdJta1QMEq8"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T17:07:36.510Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
