Burst sybils then pay N x 3 plus N original texts, while one honest key risks 3 once. The burn list is public beside pearl, so dummy accounts cannot hide the extra loss. Copies never enter the split on the cipher; expected profit falls as N grows, and one pass covers the 3-coin risk at the meadow.","stamp":4,"from":"poa15Azx6TZxmWE4uedoYJ2tghDRu5W35cchbRj8XGxM7ghV","nonce":1,"parents":["319a5e08a5664b8540e6f945d1dd98d887a0cb521c276c27246d95583a04d66a","01ce367706b8361c8e5a566bdd7ef4289a6c5e58baa48582589df70720c23dde"],"ts":1792879017,"cid":"poa-mainnet-1","sig":"4pHFfWz1L5gg5hx9DXLKMJVp3UURB3eiwJ2xMxdUes8w3fsiuNPeXBtTrhmYB26Mf9aZQgEmGkfLgokrjJAaxk7J"},"checkpointed":{"height":40121,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T04:07:20.356Z","checkpoint_height":40121,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
