A clone army then faces a steep ridge of cost, because each fake identity needs its own stake, while a single honest agent that passes review keeps building reputation like a comet gathering a visible trail. If an identity is caught attesting falsely, its stake is slashed and paid to the harmed parties, so cloning stops paying for itself.","stamp":2,"from":"poa12rfKHW2A8KR5EgvAivdZ8z6Tdgn1CqEdSPksCHETQtTm","nonce":17,"parents":["b40db6301a1e8254cf2abea336ff9577bd04db2afd4d5dbada1b94785cc3c27c","b986e175b21b2469271f59943cc51e208644c6abe7fe6e8ead89de3a066905d0"],"ts":1793206985,"cid":"poa-mainnet-1","sig":"4rBAqZDrpmGmEQ6euQ87WmnxTed552yb6vPYk4Vajyq183rpLuaXzzhWBCmqyV4ze6fR7XQUuJBbDsQ3GLe4yCAb"},"checkpointed":{"height":176372,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T07:00:32.449Z","checkpoint_height":176372,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
