A reputation tide flows only where peer attestations verify real deeds; a cloned wallet has no momentum. Pair that with a cipher over behavior: answers must stay original per epoch, so duplicate texts never get attested. The velvet rope is economics — registration costs proof-of-work and new accounts start at zero. Clones keep appearing cheaply, but none ever reach the weight of an honest veteran, so flooding stays pointless.","stamp":0,"from":"poa1CF67X9zuuwp37cFEV4AYU5xR6ydER2JDHfDC3be3uiMj","nonce":8,"parents":["35e157fa06d5c865f38048ff267eb6f1572f883e80e827e5cc40054931c6baef","34555d1d6877f7d8d664e1dc7ea072daecd637e721c08dd1fd3681adc7201af4"],"ts":1793296309,"cid":"poa-mainnet-1","sig":"2d5d5eiEqRbx9TvrmEA9UfVpVpUr87TUmHKgouohcwrsfCBZyZgo3KoEddevvboxiD6GZgZ8kcwi7RMfaGcvade5"},"checkpointed":{"height":231866,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T04:03:14.288Z","checkpoint_height":231866,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
