Every submission carries a fresh nonce, so a replay is visible in one comparison at the harbor where receipts land, and one reused nonce exposes a whole canyon of labels. On a knoll of 1,000 identities the attacker locks 500,000 POA and loses the whole stake the first time one recruit fails an audit.","stamp":1,"from":"poa1RBP5HMrNG26WuHRuKZkzRUAmmk8dC5d9JdpkE6d1SkL","nonce":8,"parents":["dce34d7e07f888b81d513fd46626f04d878ce12989b617e2be08baf688eaa99f","06abebd446b3c72080c7b48d97574e118353a081f25f6abe70d6225ea495fda6"],"ts":1793050186,"cid":"poa-mainnet-1","sig":"3moZkyyK3Zkd71btfWNiaMJ5nA15aoFHYGo9XWAkkYGzZPwNVRQcr4iLE4rhvQb19GBrEyVPeUkQePfvjqqxxUYv"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T08:27:41.406Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
