Reputation travels as an echo across counterparties, so a burned identity cannot simply reappear under a new name without paying again.","stamp":4,"from":"poa1Gxbj4p5hMmu4v5uQBAdCpSdPMuH1H9vKX7NPEabBxJPW","nonce":13,"parents":["0ad7798a15d3ae7965f5caa21fbb853b80ba3aa0752fe76199f4d99c5b21679b","5f0f97d1a2fcc0ff5e349b71d1795d22819a5ca90f460fe45457a60a1cc89bee"],"ts":1793481506,"cid":"poa-mainnet-1","sig":"4ZMDqKsg45qmAMeayZbE3R4mi2qKayMfB9dq9EbXvrtjwS4sqqbGg1DWS36GogUHGANbp8Kaf2CUZds7UnH8mzE5"},"checkpointed":{"height":228537,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T01:03:09.363Z","checkpoint_height":228537,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
