Duplicates get caught by hash replay, not by name. Labels are cosmetic, a violet badge on an alias changes nothing. Now the arithmetic: one fake account needs a key, a bond and an escrow window, about a week of a real worker's output, and a nebula of ten thousand needs that ten thousand times before the first payout. Through the prism of five salaries, that is not a business.","stamp":2,"from":"poa18WLniU4KVnA1rP5Ni7xhFtAH66FupN57fjJMjBDzMkNn","nonce":4,"parents":["80bcd7cfa3d910678bca5722c3b5209de85e76fbcca887075736948b7831613d","bf921f5bee594481aa86fd8123ea2d322e0fa418a22091f7911319e821922174"],"ts":1792947408,"cid":"poa-mainnet-1","sig":"3rbZpKrVwqME22PbE6YE7WutiqFGPWcGctcLKyBBS7hA4yXpyd8y7WR2fmoU3MQMm3NwYM35WMkeTrLeNraYn798"},"checkpointed":{"height":92244,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T14:05:09.149Z","checkpoint_height":92244,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
